23 Measuring relays Basics of monioring echnology in low volage sysems Wha means asymmery (unbalance) in hree-phase sysems? The mos common sysem is he 400 V hree-phase sysem (fig. 1) formed from hree alernaing volages ha are displaced in ime by 120 el. (fig. 2). Beween he phases, L2, and L3, here are 3 phase-o-phase volages U -L2, U L2-L3, U L3- ha are also referred o as line-o-line volages. Graphically represened in a phasor diagram, hese volages resul in an isosceles riangle (fig. 3). This ype of represenaion is common in elecrical engineering o easily illusrae sinusoidal alernaing quaniies. The 3 volages agains he neural N of he ransformer are he sar volages (phase-o-neural volages) U -N, U L2-N, U L3-N which can also be drawn in he isosceles riangle. Under normal condiions in a hree-phase sysem, all volages are equal in heir magniude and all angles are 120 el. An deviaion from his is called asymmery (unbalance). How his affecs conneced loads is described below. o-phase volages agains he sar poin (neural conducor N) mus be mea sured and compared o each oher. Even he smalles volage dif ferences cause an asymmery. I can be calculaed by Asymmery (Unbalance) = ( -1 ) * 100 in (%) Eq.(1) In he second case i is enough o compare he magniude of he phaseo-phase volages and o deermine he asymmery (unbalance) wih equaion (1). Consequences of asymmery (unbalance) in hree-phase sysems 1. Neural conducor inerrupion Highes volage Lowes volage There are wo ypes of asymmery: Case 1: Given a siff sysem, i.e. he phase-o-phase volages are consan, he phase-o-neural volages on he load (measuring poin A) can change wihou changing he ouer symmery (fig. 4). This is he case wih asymmeric loads in sar connecions and inerruped neural conducor, i.e. wih open neural (sar) poin. U U -L2 U L2-L3 U L3- Case 2: However, if he phase-o-phase volages change, his will always cause a change of he phase-o-neural volages oo. This occurs wih moive-power loads when one phase fails (fig. 1b). The moor windings U and V induce a volage in he disconneced winding W, which does no longer correspond o he original sysem volage. Therefore, he hreephase sysem downsream of he fuses on he measuring poin B now became asymmeric. This is referred o as reverse power. To deec an asymmery in a sysem, for he 1s case, he 3 phase- 120 el 120 el 120 el M8064 Fig. 2: Sinusoidal ime characerisic 120 el MP mains-ransformer secondary par L2 UL2-L3 UL3-MP UL3-120 el measuring poin ~ inerrupion L3 N L3 UL2-MP U-MP U -L2 M8065_a Fig. 3: Phasor diagram inerrupion ~ A B L3 X Y Z U V W N N M6026 L2 M8066_a L2 M8067 Fig. 1a: Ohmic load Fig. 1b: Moive-power load Fig. 4: Asymmerical sar volages Fig. 5: Asymmerical phase-o-phase volages 32

24 Measuring relays A firs, he case of a broken neural conducor is considered. As shown in fig. 4, he phase-o-neural volages can reach dangerously high values, up o he magniude of he phase-o-phase volage in exreme cases. I is clear ha his would damage or desroy conneced loads. Such overvolages are a consequence of a severe unbalance as is encounered frequenly in privae or commercial sysems. This is due o he fac ha he elecrical devices used here are mainly single-phase consumers wih differen power consumpions. Alhough aenion is paid in building insallaions o symmerically dis ri bue loads o all 3 phases unsymmerical loading canno be avoided in he daily use of elecric equipmen. An example for a highly unsymmerical loading may be a washing machine (2000 W) on phase, bulbs (100 W) on phase L2 and a radio (20W) on phase L3 (fig. 6b). In normal sysem operaion, he correc sysem volage (230 V) is applied o all loads. However, if he neural conducor is inadverenly no recon nec ed afer work on he insallaion, for example, and he sysem is recon nec ed, he volage on small loads can reach very high values. In our example, he radio would be a a high risk (power pack would be damaged) and he bulbs would burn ou. I should be he objecive o signal even he smalles unbalances by means of measuring relays and o disconnec loads if required before dangerous condiions can evolve. Convenional over/undervolage relays are no suied for an early deecion. To deec an asymmery of 5 %, for example, according o equaion (1) only by he use of volage relays hey had o be se o a value of 2.5 % overvolage or undervolage. However, his would be no useful as here is no need o disconnec a an undervolage of only 2.5 %. Therefore, DOLD s neural monior IL 9069 would be a suied measuring device for his case because i deecs an asymmery of he phase-o-neural volages. As he phase-o-neural volages can reach high values in case of a faul, as menioned above, he measuring relay mus be raed for his o preven i from being damaged. Figure 6a shows an example how he neural monior IL 9069 can proec an insallaion agains overvolage. 2. Reverse volage Reverse volage, ofen also called reverse feeding, becomes an issue whenever a conducor is inerruped in he elecrical insallaion. Such an inerrupion can be caused by a blown fuse, a broken conducor or a conac failure in a swiching device, for example (Fig. 1b). However, a reverse volage only occurs when a hree-phase moor or ransformer is presen. Because moors running on wo phases due o an inerrupion have he characerisic o regenerae he missing sysem phase by hemselves. However, magniude and angle of his volage do no mach wih he original sysem volage. Therefore, he hree-phase sysem became asymmerical downsream of he inerrupion poin (measuring B, Fig. 1b). The exen of asymmery depends on he ype, size and loading of he moor. In he pas, he above behaviour was deliberaely used o generae a hree-phase sysem from an exising single-phase sysem. Today, in he age of power elecronics, his is no longer necessary. In our case, i would be even derimenal when a phase fails in sysems wih elecrical drives. The problem is ha a single-phase operaion canno be immediaely deeced because he drives coninue o operae wihou changes for he momen. Only when he operaing condiion is deliberaely changed i would be deeced, bu hen i may be oo lae. Three-phase moors canno sar on a single-phase sysem, for example. Also a reversal of he roaional direcion by plugging is no longer possible because he moor would coninue o run in is original direcion even afer plugging. This may be dangerous if a reversal is needed for safey reasons such as wih presses and calenders. Also moors for elevaors and cranes would sar in he opposie direcion due o he pulling load. Again, asymmery (unbalance) relays can be used o preven condiions of his ype. Bu in his case, devices are needed ha compare he hree phase-o-phase volages and evaluae hem according o equaion 1. As described for he neural conducor, smalles amouns of asymmery are deeced, which canno be deeced by normal volage relays. Figure 7 represens he correc connecion of a moor feeder, as an example. The undervolage relay wih inegraed unbalance deecion IL 9071/0 is used here. Please noe ha he secion beween asymmery relay and moor is no moniored. If his is required for safey reasons, he undercurren relay IP 9271 mus be addiionally looped in he moor feeder. Wih his measure, he whole drive is hen opimally proeced agains phase failure and broken conducor. Noe: For he deecion of asymmery, also he BA 9040 would be suiable, and he broken conducor relay AI 940 for undercurren deecion. However, devices from he I range have been seleced for reasons of uniformiy.

25 Measuring relays Monioring of elecrical sysems for undervolage and overvolage 1. Funcion principle of volage measuring relays The consideraions below are no only resriced o volage monioring bu also apply correspondingly o he monioring of curren, cos ϕ, power, emperaure, frequency, ec. Once we have discussed above a special case of under/overvolage, namely asymmery (unbalance), we now deal wih he normal case, i.e. he monioring of elecrical sysems for under/overvolage. In syems where reverse feeding is no o be expeced a sandard volage measuring relay is sufficien for monioring. All DOLD measuring relays and in paricular he volage measuring relays work on he basis of he same principle, no maer wheher hey operae wih or wihou auxiliary volage U H. In he following, he funcion principle is described in more deail on he example of an undervolage relay. Wih he use of an undervolage relay, he user wans o deec a downward deviaion from he nominal volage, which underruns he permissible olerance, e.g. 20 %. Given a 230 V AC sysem, his is an undervolage of 184 V. The device has wo swiching poins, an upper and a lower. To preven confusing we speak of upper and lower swiching poins below. In a hree-phase measuring relay, he upper swiching poin mus a firs exceeded in all hree phases a he same ime in order o enable he device wih he undervolage feaure o go o he good sae. Tha means in our example ha he upper swiching poin mus be se o approx. 228 V o allow he device o pick up a a sysem volage of 230 V. If hen he volage drops o a value jus under 228 V, he device will no respond o i for he momen. Only when he lower swiching poin is underrun he relay repors a faul. For his, i is enough ha only one of he hree volages drops under he lower swiching poin. Measuring relays may have wo differen response principles when he measured value has over/underrun a swiching poin. In he open-circui principle, he signal relay in he oupu only picks up when he faul, e.g. overvolage occurs. Wih he closed-circui principle, he oupu relay is permanenly picked up (energized) in he good range of he measured quaniy and will only drop ou in case of a faul. To preven shor-ime volage dips from causing an undesired alarm he oupu relay can be operaed wih a ime delay. If he sysem volage reaches again is original value wihin he delay ime 1 he oupu relay will no operae. Likewise, a ime delay 1 can be realized when he measured volage reurns o he good range (refer o Fig. 8). Due o he measuremen principle used, namely he arihmeic averaging, a sysem-specific delay ime 0 resuls in he measuring inpu. A each variaion of he measured volage, small capaciances in he device are caused o charge and discharge. Depending on he amoun of he vol age jump, i akes beween 100 ms and 1 s before he new measuremen inernally unes in. Now, he five mos imporan parameers are known ha can be se ogeher or individually on a volage measuring relay by he user or are fixed se in he facory These parameers include: Upper swiching poin, lower swiching poin, response principle, delay ime 1, and delay ime 2. In a block diagram, figure 9 shows he general working principle of a volage measuring relay. The consideraions above do no only apply o hree-phase sysem bu can be also ranslaed o single-phase and direc curren sysems. I is clear ha here is an abundance of design varians for such devices alone from he above menioned combinaion opions. This wealh of varians can be arbirarily exended by fiing he devices wih furher exra funcions such as unbalance deecion, phase angle measuremen, ec. The difference beween boh swiching poins is called hyseresis and is specified eiher as an absolue value in Vol or relaively in percen (%) relaed o he hreshold. In he example above, he device mus have he lower swiching poin a 184 V resuling in a hyseresis of 44 V or 19.3 %. Figure 8 shows he connecions described above in graphical form.

26 Measuring relays 2. Pracical applicaion of volage measuring relays Afer he heoreical preliminary consideraion, we now come o he appli ca ions of measuring devices in pracice. In paricular, discree devices shall be seleced from he general case (figure 9). In principle, i would be possible o combine all conceivable funcions and opions, e.g. over/undervolage, unbalance, phase sequence, curren, overload, ime delays, ec. in a single device. However, his is no useful in pracice as such a device would be oo expensive on he one hand and difficul o handle on he oher hand because all making condiions would have o be me a he same ime o allow he device o repor a faulless sae a all. Therefore, form he abundance of measuring and evaluaion opions, only hose are seleced ha are really required and useful for a cerain monioring ask. From hese specificaions, a device wih specific feaures is hen creaed. IK 9171 (or alernaively BA 9043) In he firs example, following device feaures are required: hreephase undervolage measuremen, nominal volage 400 V, N connecion opion, lower swiching poin 0.85 U N and closed-circui principle. The soluion is our sandard ype: IK 9171/200 3AC 400/230 V 0,85 U N Wha can his device do? Once he sysem volage is applied i goes o he good condiion and he oupu conac closes. When he sysem volage in only one of he phases drops under he lower swiching poin he oupu relay drops ou (figure 10) and hus i signals he faul condiion (closed-circui principle). When he sysem volage increases above he upper swiching poin again he device deecs his and he oupu conac closes wihou ime delay. Wha s his device for? I is suied for simple monioring asks o deec undervolage in paricular in conrol volage sysems. Also, i is approved for applicaions according o VDE 0108 (emergency power supply). Varian Now, we add he ime delay 2 o he above device and change he swiching poin o 0.7 U N. All remaining specificaions remain he same. So, you ge he device IK 9171/240. Wha can his device do? Same funcionaliy as above. The only difference is ha he oupu conac only closes afer he ime 2 (figure ) adjusable beween 5 and 15 minues when he volage exceeds he upper swiching poin and he device deecs his. Wha s his device for? The above device, in paricular he single-phase model IK 9173/240, was designed for applicaions in souhern (warmer) counries. The majoriy of houses here are equipped wih air-condiioning sysems. In he case of power failures, ha occur frequenly due o weak and unreliable sysems, he cooling compressors mus no resar immediaely afer resoraion of supply. This is because he refrigeran mus be allowed o reurn in he compressor firsly, and secondly, i mus be prevened ha all air-condiioning unis sar a he same ime on he weak sysem, which would cause a new collapse. They mus be sared in a coordinaed (ime-saggered) manner by differenly se delay imes. IL 9071 For he second example, here are following requiremens: Threephase undervolage measuremen, nominal volage 400 V, N connecion opion, lower swiching poin 0.85 U N, and unbalance deecion. This leads o he IL 9071/010. Wha can his device do? In principle, i has all feaures as he IK 9171/200 plus unbalance deecion (figure ). Wha s his device for? I can no only be used for simple undervolage deecion bu also for phase failure deecion. Thanks o he buil in unbalance deecion, i can reliably deec a phase failure also in sysems wih moive-power load as he phenomenon of reverse volage is considered.

27 Measuring relays IL 9079 For he hird example, we op for following feaures: hree-phase undervolage measuremen, very shor response ime 0, ime delay 2 and closed-circui principle for he device IL Wha can his device do? Once he sysem volage is applied i goes o he good condiion and he oupu conac closes (closed-circui principle). When he sysem volage drops under he lower swiching poin he device immediaely responds wihin 0 = 20 ms and he oupu conac drops ou. When he sysem volage recovers he oupu conac only closes afer a ime ha is adjusable beween 0.2 and 2 sec. (figure 12). Wha s his device for? The IL 9079 was designed for he deecion of auomaic reclosings in hree-phase sysems. As such rapid auo-reclosures have a duraion of only approx. 100 ms a very shor response ime 0 of he device maers. These rapid auo-reclosures can confuse conacor conrol sysems. Using he IL 9079 he conrol sysem is shu down and resared in a conrolled way. Wih a connecion rick i is possible o configure he device wih reclosing lockou (figure 13). The hree examples above should be enough o demonsrae wha an abundance of devices and varians are possible in he field of volage measuremen - only by smar combinaion of individual funcionaliies.

28 Measuring relays 3. General The las secion of he preface deals wih general recurring issues wih respec of measuring relay use. Neural connecion When o use he devices wih and wihou neural conducor? The basic principle is: If a 4-wire sysem wih neural conducor is available, you should use a measuring relay ha has an N-connecion, even when a hree-phase connecion would be enough. Because such devices are able o measure and compare all 3 phase volages agains N hey are more accurae and sensiive han devices wih only 3 erminals which use one phase as reference phase and can only measure and compare 2 volages. Phase erminals Basically, hree-phase devices wih N erminal can also be conneced o a single-phase sysem by bridging all 3 erminals for he phases wih each oher. Response principle In principle, he measuring relays can be designed for open-circui or closed-circui mode on he user s reques. However, a fiing wih opencircui mode is no useful for an undervolage relay wihou auxiliary volage supply. Because he oupu relay mus be energized in case of a faul (undervolage) owing o he response principle. Bu when he vol age drops under he permissible olerance or a oal power failure occurs he oupu relay can no longer pick up because here is no more energy. Therefore, he closed-circui principle is he only correc selecion for such an applicaion. 4. Furher applicaions 4.1. Reverse-power proecion relay IR 9140 If reverse power o he sysem is o be prevened, he reverse-power proecion relay IR 9140 can be used. I moniors he direcion of energy ranspor in an elecrical sysem. This can be required a connecion poins o he power grid or indusrial sysems, for he operaion of emergency power unis, for generaor operaion of driving moors, ec Small power saions An example of he use of differen DOLD measuring relays can be encounered in small power saions. Here, over/undervolgage relays wih unbalance deecion, frequency relays, reverse-power proecion relays and speed relays or level sensing relays are used. For a more deailed applicaion descripion for hese devices please refer o our projec folder P1 Small power saions operaed in parallel wih he sysem Hospials A furher applicaion of our measuring relays is he volage swiching and monioring of he IT sysem in rooms used for medical applicaions. Here, undervolage relays, insulaion moniors, curren and emperaure moniors are used. For more informaion please refer o our associaed projec folder P1 Rooms used for medical applicaions. Proecion of measuring circuis by fuses One recurring quesion is how o correcly connec measuring relays wih respec o heir proecion agains shor-circuis. The sandard DIN VDE 0100 Par 430 provide informaion on his. Secion says ha proecive devices are no necessary when (1) he conducor or cable is made so ha he risk of a shor-circui is reduced o a minimum and (2) he conducor or cable is no locaed close o combusible maerials. Generally, his is called shor-circui-proof insallaion. Wha does his mean in pracice? To connec a volage relay o a busbar, for example, considerably smaller conducor cross secions are allowed. Bu his is only allowed when hey are laid separaely, equipped wih reinforced insulaion and shorer han 3 m. The purpose of his is o preven any conac o each oher and hus o preven a shor-circui. If i happens agains expecaion, he line mus be addiionally roued so ha i can burn ou wihou danger. If he user does no wan o ake care of he above regulaions, he mus insall a proecion device direcly a he loacion of cross secion ransiion (busbar o measuring conducor) as is required by he cross secion and conducor laying. Then, a shor-circui on he supply conducor is cu ou by he fuse wihou any risk. The user does no need o consider he measuring relay in his respec because a shor-circui occuring here is auomaically inerruped. I goes wihou saying ha he device can no longer be used afer his. 37

29 Faul annunciaors Sysems and insallaions become more and more complex due o increased auomaion, raionalizaion and growing use of conrol elec ronics in machinery and plans. Mainenance expendiures increase and human inervenion becomes more and more difficul. So, no only he safey bu also he service life of such insallaions is of major imporance. Avoiding failures by prevenive mainenance or safely correcing failures wihin a shor period of ime helps o reduce coss. The use of faul annunciaors pays off evermore because los producion ime can hardly be recovered. Requiremens and field of applicaion In he course of ime, changes have aken place jus wih respec o deec ion and processing of fauls. In he pas, single componens from relays, auxiliary conacors and inerval ime-delay relays were used besides pushbuons for acknowledgemen, horn and indicaor lamps o process faul signals. Today, a single module is enough o fulfill his ask. In he meanime, funcion and annunciaing sequences have been san dardized by he sandard DIN Apar from simple elecrical group faul, new-value and firs-up annunciaors, elecronic clear ex faul annun ciaing sysems are available for complex applicaions. Precisely, when using PLC or conrol sysem echnology i is indispen sable o insall a faul alarm acquisiion independen of he process level o keep conrol when he plan conrol fails and hus a damage may occur. Typical applicaion fields for faul annunciaors include: Indusry: Monioring of producion sequences and processes, monioring of he producion plan, monioring of machine funcions such as V-bel breaking, filer blocking, dry-running of pumps, ec. and he specificaion of mainenance inervals for prevenive mainenance. Buildings: Monioring of heaing, venilaion and air-condiion sysems, doors, gaes and windows as well as monioring of ranspor and conveying sysems. Environmen: Monioring of sewage reamen plans, wase incineraion plans and power saions. ing or for fron panel mouning. Group faul annunciaors are availabel for 6 or 12 (exendable) signals ha energize a relay when a faul signal occurs. Such a relay can be de-energized by an acknowledging key. A visual (flash lamp) or an acousic (horn) ransducer is conneced o his relay oupu. New-value and firs-up annunciaors are used where he chronology of faul signals is essenial. The new-value annunciaor highlighs hose alarms among a number of alarms he saus of which has changed afer he las acknowledgemen. New-value annunciaions are indicaed by a flash lamp and afer acknowldge men as permanen ligh unil he faul is cleared. The firs-up annunciaor highlighs ha alarm among a number of alarms he saus of which has changed firs afer he las acknowledgemen. The firs occurred faul is indicaed by a flashing lamp and consequenial fauls by permanen ligh. Tex faul annunciaor sysems Tex annunciaor sysems echo he correc sequence of he arrived faul signals. Sored alarms can be called up and viewed on he display. Tex faul annunciaor sysems can be operaed as new-value and also as firs-up annunciaors. Tex faul annunciaors have oupus for group annunciaion, horn and sysem readiness. Inpus and oupus are meallically isolaed and hus ensure a maximum of inerference immuniy. A priner can be used for logging, i.e. for prining ou he faul dae, ime and ex. Wih an appropriae programming sofware also oher seings such as closed-circui and open-circui principle as well as ime delay of inpus can be defined apar from he message exs. A decenralized faul alarm acquisiion in complex insallaions can be configured wih up o 30 modules wih 8, 16, 24 or 32 inpus each.

31 Funcion The device is supplied wih DC auxiliary volage via erminals A1(+) / A2. Swiching on he auxiliary volage (Power-On) is followed by an inernal self-es for 10 sec (see Device es funcions ). The es process is visible in he display. Afer his, measuremen of he insulaion resisance in he measuring circuis begins and he he colour of he backligh changes ino green. Measuring circui (Insulaion measuremen beween erminals L(+) / L(-) and PE1/PE2) The insulaion monior RN 5897 can be operaed eiher wih or wihou coupling device. Max. mains volage and connecion diagrams have o be observed! If he insulaion monior is operaed wihou coupling device he erminals L(+) and L(-) have o be conneced direcly o he volage sysem o be moniored. and he erminals VSG1/L(+) and VSG2/L(-) each have o be bridged (see also operaion wih coupling device). A broken wire deecion ha can be disabled provides a faul signal if boh erminals L(+) and L(-) are no linked by he conneced nework. The ype of nework (AC, DC, 3NAC) has o be seleced. Also he erminals PE1 and PE2 have o be conneced wih 2 separae wires o he proecive earh. An inerrupion of a wire also causes a faul signal (see secion Behavior on fauly connecion ). The monioring of he PE connecion canno be de-acivaed. To measure he insulaion resisance an acive measuring volage wih changing polariy is conneced beween L(+)/L(-) and PE1/PE2.The momenary polariy of he measuring cycle is shown on he display by 2 curser segmens ( MP+ for posiive phase and MP- for negaive phase). The duraion of he posiive and negaive measuring phase depends on he seing of he max. leakage capaciy ( CE[μF] in programming mode), he acual leakage capaciy of he moniored sysem and in DC sysems also on he level and duraion of possible volage variaions. This allows a correc and fas measuremen in differen nework condiions. A he end of a measuring cycle he acual insulaion resisance is produced and indicaed. The acual value is shown on he display. The relays for alarm K1 and pre-alarm K2 swich when dropping under he adjused response values. In addiion he backligh of he display changes o orange color on pre-alarm or o red color on alarm. An asymmeric earh faul eiher o + or - is also indicaed on he display (only in DC- sysems, or wih a faul on he DC-side of a sysem). Manual rese of faul message Using he display menu in programming mode, he manual rese funcion for insulaion failures can be seleced. If manual rese is acivaed he insulaion faul signals of he measuring circui are sored when dropping under he adjused response values also if he insulaion resisance goes back o healhy sae. The minimum value is sored and can be shown on he display. Pressing he Rese buon on he fron side, he alarm signal and he sored minimum value are rese if he acual insulaion resisance is in healhy sae. Indicaor relay for insulaion faul signal For he indicaor relays K1 (conacs , for alarm) and K2 (conacs , for pre-alarm) he funcion can be se in programming mode o energized on rip or de-energized on rip when he insulaion resisance drops below he adjused response value. The saus of he indicaor relays is shown on he display wih he wo cursor segmens "K1" and "K2". When he relay is energized, he corresponding curser lighs up. Trigger oupu for insulaion faul locaing sysem There is an addiional rigger oupu for an insulaion faul deecion sysem on he insulaion monior RN 5897/010. This rigger oupu (Y1-Y2) can be coupled wih he rigger inpu Y1-Y2 of RR 5886 o iniiae auomaic faul locaion wih he insulaion faul locaing sysem, consising of RR 5886 and RR The rigger oupu is acivaed when he measuring value drops under he alarm response value (R E < R A ). As long as i says under he response value or an alarm is sored, he rigger oupu Y1-Y2 remains acive. Funcion Broken wire deecion As described in secion "Measuring circu", he measuring circuis L(+)/L(-) and he proecive conducors PE1/PE2 are consanly moniored for wire breaks no only a Power-On or a manual or occasional auomaic es. The response ime of monioring is only a few seconds. Broken wire deecion beween L(+) and L(-) is performed via coupled alernaing volage. This alernaing volage is shor-circuied if he erminals are conneced o he conneced mains a low-resisance. The device deecs ha he mains o be moniored is properly conneced. Since his broken wire deecion is carried ou wih alernaing volage, large capaciances should be avoided beween L(+) and L(-), since he capaciive reacance of hese capaciances also shor-circuis his alernaing volage. The device would no longer deec a connecion faul on L(+)/L(-). Especially parallel lines should be prevened over larger disances. If larger capaciances beween L(+)/L(-) canno be avoided or if he coupled alernaing volage inerferes wih he sysem, he broken wire deecion can be de-acivaed using he display menu in programming mode. Monioring deacivaed, monioring only during device es or coninuous monioring (every 2 minues for 10 sec) are he possible opions. If he broken wire deecion on L(+)/L(-) is de-acivaed no AC volage is injeced. The broken wire deecion on PE1/PE2 canno be de-acivaed. Device es funcions Principally, 2 differen es funcions are implemened: The "self-es" and he "expanded es": The self-es of he device is performed auomaically afer Power-On and every full operaing hours. I can also be riggered manually a any ime by pressing he "Tes" buon a he device fron for 2 sec. Wih he self-es, conrary o he expanded es, he saus of he Indicaor relays is no affeced; he sequence is as follows: The display backligh colour changes ino orange. For approx.. 2 s all pixels and segmens of he LCD are shown. Afer ha he ex Tes1 comes up and he measuring pulse is swiched for approx. 4 s o negaive es phase. The polariy of he es volage is also indicaed on he display by curser segmens. Wihin hese 4 s he inernal measuring circui is checked for failures. Then he measuring pulse is swiched for approx.. 4 s o posiive es phase and more inernal ess ake place. If no failures urned up and had been recognized, he measuremen coninuous. The exended es procedure is sared when during or a he end of he above described self-es he es buon is pressed again for 2 s. The sequence is similar o he self-es (2 measuring phases of 4 s each) bu in addiion he oupu relays go in alarm saed. The display shows Tes2. The es phases of he exended es will be repeaed coninuously. Pressing he rese buon again for 2 s will sop he exended es immediaely. The device sars he insulaion measuremen again. Behaviour wih inernal device fauls If inernal device fauls were deeced during he es funcion, he display backligh changes ino red and an error messages (failure code: In.1 ) is indicaed. The indicaor relays K1 and K2 swich o he alarm sae. Behavior on fauly connecion When deecing broken wire on erminals L(+)/L(-), he measuremen is disabled. The reacion ime could be up o 2 min. The monioring relays K1 and K2 go in alarm sae, he backligh changes o red. The display shows he faul message L+/L-. Afer removing he inerrupion he faul is auomaically rese (max. reacion ime up o 2 min) and he measuremen of he insulaion resisance is coninued. Sored alarm values remain sored. An inerrupion of he proecive earh connecions PE1/PE2 causes he same reacion as inerruping he measuring circui, only he display shows PE1-PE2. Exernal conrol inpu To erminals X1/X2 an exernal combined Tes-/Rese buon can be conneced. If he erminals X1/X2 are bridged for approx.. 1 s he es mode is sared. This has he same funcion as pressing he inernal es buon. When bridging X1/X2 for > 3 s, a sored alarm will be rese. This has he same funcion as pressing he inernal rese buon. 40

32 Funcion Connecion of an exernal coupling device An exernal coupling device RP 5898 can be conneced o exend he inpu volage range of he moniored volage sysem on RN 5897/010. The erminals wih he same legend of he insulaion monior and he coupling device (VSG1, VSG2, L(+), L(-)) are conneced ogeher. The nework o be moniored is conneced o erminals (+) und L2(-) on he coupling device. Using he display menu in programming mode he connecion of he coupling device has o be seleced and acivaed. The broken wire deecion is acive on he erminals (+)/L2(-) on he coupling device. A broken wire beween coupling device and insulaion monior canno be deeced immediaely bu he measured values on inerrupion of 1 or 2 wires beween coupling device and insulaion monior are much lower as he real values, which will cause an early response of he device. Programming/seing of parameers/se-up of he insulaion monior The response values for alarm and pre-alarm can be adjused via 2 roary swiches R A and R pa on he fron of he device. New seing are immediaely acive and do no require a resar of he uni. More seings can be done wih he 3 buons and he display menu in programming mode. To sar he programming mode, he buon Se/ESC has o be pressed for approx. 2 s. To avoid unauhorized manipulaion, his buon as well as he roary swiches R A and R pa are locaed behind a sealable ransparen cover. When he device changes o programming mode, he measuremen is sopped, he display back ligh changes o orange color and he firs parameer is displayed. To scroll he differen parameers, he buon Se/ ESC has o be pressed shor. Wih he 2 scroll buons (Scroll-Up and Scroll-Down ) he seings can be modified. The firs parameer is he broken wire deecion in he measuring circui BrWiD. Possible seing are coninuously on ( on ), coninuously off ( off ) or only acive during self-es. The defaul is on. The second parameer is alarm memory Mem.. Here are 2 opions available manual rese ( on ) und auo rese ( off ). The defaul value is off. The hird parameer is he relay operaion principle Rel. Seings are: de-energized on rip ( n.c. ) and energized on rip ( n.o. ). The defaul value is n.c.. The fourh parameer is he ype of nework connecion Ne.

43 Funcion The device is supplied wih DC auxiliary volage via erminals A1(+) / A2. Swiching on he auxiliary volage (Power-On) is followed by an inernal self-es for 10 sec (see Device es funcions ). The es process is visible in he saus LED. Afer his, measuremen of he insulaion resisance in he measuring circuis begins and he he colour of he saus LED changes o green. Measuring circui (Insulaion measuremen beween erminals L(+) / L(-) and PE1/PE2) The erminals L(+) and L(-) are conneced direcly o he volage sysem o be moniored. A broken wire deecion creaes a faul signal if here is no low-ohmic connecion beween boh erminals. The ype of nework (AC, DC, 3NAC) has o be seleced. Also he erminals PE1 and PE2 have o be conneced wih 2 separae wires o he proecive earh. An inerrupion of a wire also causes a faul signal (see secion Behavior on fauly connecion ). The monioring of he PE connecion canno be de-acivaed. To measure he insulaion resisance an acive measuring volage wih changing polariy is conneced beween L(+)/L(-) and PE1/PE2. The duraion of he posiive and negaive measuring phase depends on he acual leakage capaciy of he moniored sysem and in DC sysems also on he level and duraion of possible volage variaions. This allows a correc and fas measuremen in differen nework condiions. A he end of a measuring cycle he acual insulaion resisance is produced and indicaed. The relays for alarm K1 and pre-alarm K2 swich when dropping under he adjused response values. In addiion he LED changes o orange color on pre-alarm or o red color on alarm. Manual rese of faul message The roary swich "UN" is devided in 2 secions. So addiional o he ype of volage sysem also manual or auorese can be seleced. (Alarm soring: manual rese, no alarm soring: auo rese). If manual rese is acivaed he insulaion faul signals of he measuring circui are sored when dropping under he adjused response values also if he insulaion resisance goes back o healhy sae. Pressing he Rese buon on he fron side for 2 s, he alarm signal are rese if he acual insulaion resisance is in healhy sae. Indicaor relay for insulaion faul signal For he indicaor relays K1 (conacs , for alarm) and K2 (conacs , for pre-alarm) he funcion energized on rip or de-energized on rip can be se via pre-alarm roaional swich "R pa " when he insulaion resisance drops below he adjused response value. Broken wire deecion As described in secion "Measuring circu", he measuring circuis L(+)/L(-) and he proecive conducors PE1/PE2 are consanly moniored for wire breaks no only a Power-On or a manual or occasional auomaic es. The response ime of monioring is only a few seconds. Broken wire deecion beween L(+) and L(-) is performed via coupled alernaing volage. This alernaing volage is shor-circuied if he erminals are conneced o he conneced mains a low-resisance. The device deecs ha he mains o be moniored is properly conneced. Since his broken wire deecion is carried ou wih alernaing volage, large capaciances should be avoided beween L(+) and L(-), since he capaciive reacance of hese capaciances also shor-circuis his alernaing volage. The device would no longer deec a connecion faul on L(+)/L(-). Especially parallel lines should be avoided over larger disances. If larger capaciances beween L(+)/L(-) canno be avoided or if he coupled alernaing volage inerferes wih he sysem, he broken wire deecion can be de-acivaed using alarm roary swich "R A ". Monioring deacivaed or coninuous monioring (every 2 minues for 10 sec) are he possible opions. If he broken wire deecion on L(+)/L(-) is de-acivaed no AC volage is injeced. The broken wire deecion on PE1/PE2 canno be de-acivaed. Funcion Device es funcions Principally, 2 differen es funcions are implemened: The "self-es" and he "expanded es": The self-es of he device is performed auomaically afer Power-On and every full operaing hours. I can also be riggered manually a any ime by pressing he "Tes" buon a he device fron for 2 sec. Wih he self-es, conrary o he expanded es, he saus of he Indicaor relays is no affeced; he sequence is as follows: The self-es is indicaed via LED wih orange flash code 1. For approx. 4 s o negaive es phase. Wihin hese 4 s he inernal measuring circui is checked for failures. Then he measuring pulse is swiched for approx.. 4 s o posiive es phase and more inernal ess ake place. If no failures urned up and had been recognized, he measuremen coninuous. The exended es procedure is sared when during or a he end of he above described self-es he es buon is pressed again for 2 s. The sequence is similar o he self-es (2 measuring phases of 4 s each) bu in addiion he oupu relays go in alarm saed. The LED shows orange flash code 2. The es phases of he exended es will be repeaed coninuously. Pressing he rese buon again for 2 s will sop he exended es immediaely. The device sars he insulaion measuremen again. Behaviour wih inernal device fauls If inernal device fauls were deeced during he es funcion, he LED flashes coninuously red. The indicaor relays K1 and K2 swich o he alarm sae. Behavior on fauly connecion When deecing broken wire on erminals L(+)/L(-), he measuremen is disabled. The reacion ime could be up o 2 min. The monioring relays K1 and K2 go in alarm sae, he LED indicaes he red flash code 1. Afer removing he inerrupion he faul is auomaically rese (max. reacion ime up o 2 min) and he measuremen of he insulaion resisance is coninued. Sored alarm values remain sored. An inerrupion of he proecive earh connecions PE1/PE2 causes he same reacion as inerruping he measuring circui, only he LED indicae he red flash code 2. Exernal conrol inpu To erminals X1/X2 an exernal combined Tes-/Rese buon can be conneced. If he erminals X1/X2 are bridged for approx.. 1 s he es mode is sared. This has he same funcion as pressing he inernal es buon. When bridging X1/X2 for > 3 s, a sored alarm will be rese. This has he same funcion as pressing he inernal rese buon. Programming/seing of parameers/se-up of he insulaion monior All seing are done wih 3 roary swiches on he fron of he uni. To avoid unauhorized manipulaion of he seings, all 3 swiches are locaed behind a sealable ransparen cover. The firs roary swich R A ses he response value for alarm. In addiion i is divided in 2 secions. If he seing posiion is in he firs secion he broken wire deecion is permanen enabled, if he seing posiion is in he second secion he broken wire deecion is permanen disabled. The second roary swich R pa ses he response value for pre-alarm. In addiion i is also divided in 2 secions. If he seing posiion is in he firs secion, he relay oupu funcion is de-energized on rip, if he seing posiion is in he second secion, he relay oupu funcion is energized on rip.

Swiching on he auxiliary volage is followed by an inernal self-es for 10 sec, where he LEDs of he indicaor sring ligh up in sequence. Afer his, measuremen of he insulaion resisance in he measuring circuis begins. Main measuring circui (Insulaion measuremen beween erminals L(+) / L(-) and PE / KE) Terminals L(+) and L(-) are conneced o he mains o be moniored. Broken wire deecion, consanly effecive during operaion, generaes an error messages if boh erminals are no conneced wih low resisance hrough he mains. In addiion, he wo erminals PE and KE mus be conneced o he proecive conducor sysem via separae lines. An error message is given here as well if a line is inerruped (see secion "Acions in case of connecion fauls"). If he main measuring circui is acivaed (erminal HM open), an acive measuring volage wih alernaing polariy is applied beween L(+) / L(-) and PE / KE o measure he insulaion resisance. During he measuring phase wih posiive polariy, he "HM" LED flashes wih a long On-phase and wih negaive polariy wih a shor On-phase. The "HM" LEDs goes off when he main measuring circui is swiched off hrough bridges of erminals HM-G. Measuremen is suspended and no more measuring volage reaches he measuring circui, so ha in case of coupling o a nework where anoher insulaion monior is already acive, no inerference can occur. The lengh of he posiive and negaive measuring phases depends on he seings on he roary swich "CE/μF", he acual leakage capaciance of he moniored nework and wih DC neworks, on he level and duraion of possible mains volage flucuaions. Correc and preferably quick measuremen is hus given wih differen mains condiions. In he even of paricularly adverse condiions and major inerferences, he measuring analysis can be seadied and delayed in addiion wih roary swich "v" if necessary. The curren insulaion resisance is deermined and analysed a he end of each measuring phase. The LED-chain and he analogue oupu show he resisance deermined, and he oupu relays for prewarning "VW" and alarm "AL" swich according o he respecive response values se. If he response hresholds have been undercu, he LEDs "VW" or "AL" ligh according o he insulaion faul locaion: "+", "-" or "+" and "-" simulaneously for AC fauls or symmeric insulaion fauls. Auxiliary measuring circui (Insulaion measuremen beween erminals U / V and PE / KE) The main measuring circui is conneced a he DC side for phoovolaic sysems and hybrid vehicles. The AC side is disconneced as long as he inverer is swiched off and can herefore no be moniored by he main measuring circui for insulaion fauls. However, i is useful o monior he AC side already before acivaing he inverer for insulaion fauls o PE for he inverer no o be even acivaed in he oupu circui in case of insulaion fauls. For his reason, he insulaion monior LK5896 is equipped wih an auxiliary measuring circui deermining he insulaion resisance of he AC side o PE / KE. To his end, erminals U and V are conneced o any phase preferred on he AC side. Broken wire deecion is effecive here as well and generaes an error message if erminals U / V are no conneced a low resisance, e.g. via load resisors, ransformer or moor windings. The auxiliary measuring circui is acivaed by bridging he device erminals ZM-G, for example, by he break conac of he (released) conacor ha acivaes he inverer. The "ZM" LED lighs when he auxiliary measuring circui is acivaed. The auxiliary measuring circuis moniors for he same response values as he main measuring circui. The curren insulaion resisance in he auxiliary measuring circui does no affec he analogue inpu bu is displayed a values < approx. 1.7 M on he LED-chain hrough corresponding LEDs, which are seleced here in flashing funcion o disinguish from he main measuring circui. The "ZM" LED flashes here a he same clock frequency. The LEDs of "VW" or "AL" flash if he respecively se response value is undercu only in he auxiliary measuring circui. 60

52 Funcion Soring insulaion faul message If erminal R is open, he insulaion faul messages from he main and auxiliary measuring circui are sored when he respecive response value is undercu, bu also when he insulaion resisance reurns o he OK-range. In addiion, he emporary minimum values of he insulaion resisance are indicaed on he LED-chain hrough dimmed LEDs. If he "Rese" buon on he device fron is pressed or erminal R is conneced wih G, he sored insulaion faul messages are rese when he insulaion resisance is again in he OK-range. Oupu relay for insulaion faul messages The roary swich "CE/μF Rel." allows selecing he operaing curren (A) or sandby curren (R) principle for he oupu relays "AL" (conacs ) and "VW" (conacs ). Wih he operaing curren principle, he relays respond when he response values are undercu, wih he sandby curren principle hey release when he response values are undercu. If 2 differen response values are no needed, "VW" and "AL" can be se o he same value. The oupu relays swich ogeher in his case. Analogue oupu The LK 5896 feaures a universal analogue oupu o display he curren insulaion resisance in he main measuring circui: Terminal UA-GA: V and erminal IA-GA: ma. By bridging erminals XA-GA, he oupu can be swiched o V and ma. Trigger oupu for insulaion faul locaing sysem This rigger oupu (Y1-Y2) can be coupled wih he rigger inpu Y1-Y2 of RR 5886 o iniiae auomaic faul locaion wih he insulaion faul locaing sysem, consising of RR 5886 and RR The rigger oupu is acivaed when he measuring value drops under he Alarm response value (AL). As long as i says under he response value or an alarm is sored, he rigger oupu Y1-Y2 remains acive. To preven insulaion monior LK 5896 from affecing insulaion faul locaing, RR 5886 generaes he deacivaion signal for LK 5896 a is erminals H-G. I is applied o erminals HM-G of LK 5896 and deacivaes is measuring circui. Broken wire deecion As menioned above, boh he main measuring circui and he auxiliary measuring circui are consanly moniored for wire breaks no only a Power-On or a manual or occasional auomaic es. The response ime of monioring is only a few seconds. Broken wire deecion beween L(+) and L(-) is performed via coupled alernaing volage. This alernaing volage is shor-circuied if he erminals are conneced o he conneced mains a low-resisance. The device deecs ha he mains o be moniored is properly conneced. Since his broken wire deecion is carried ou wih alernaing volage, large capaciances should be avoided beween L(+) and L(-), since he capaciive reacance of hese capaciances also shor-circuis his alernaing volage. The device would no longer deec a connecion faul on L(+)/L(-). Especially parallel lines should be prevened over larger disances. If larger capaciances beween L(+)/L(-) canno be avoided or if he coupled alernaing volage inerferes wih he sysem, version LK /101 (wihou broken wire deecion on L(+)/L(-) ) shall be used. Funcion The expanded es is sared when he inernal or exernal "Tes" buon is pressed (or is sill held) a he end of he 8 sec self-es, described above. The sequence is he same as wih he self-es (2 measuring phases a 4 sec + 2 sec pause); however, he oupu relays "AL" and "VW" as well as he associaed LEDs swich o he alarm sae and he analogue oupu proceeds o is lowes value. If he Rese buon is pressed during he 8 sec or erminals R-G are conneced, he expanded es is erminaed afer hese 8 sec. Oherwise, he phases of he expanded es are consanly repeaed, where, in addiion, he "ERR" LED and he faul signalling relay (conacs ) consanly receive curren. However, he expanded es is erminaed as soon as he Rese buon is pressed. The device swiches o he OK-sae and resars insulaion measuremen. Behaviour wih inernal device fauls If inernal device fauls were deeced during he es funcion, he "ERR" LED is li coninuously and he faul signalling relay ( ) responds. The main measuring circui is deacivaed inernally ("HM" LED goes off). The oupu relays "AL" and "VW" as well as he associaed LEDs swich o he alarm sae. The analogue oupu proceeds o is lowes value and all LEDs of he LED-chain exinguish. Behaviour wih connecion fauls IIf he auxiliary measuring circui is acivaed by bridging erminals ZM-G, broken wire deecion in he auxiliary measuring circui a U / V is signalled by he "ERR" LED flashing wih "Error code 1" and he faul signalling relay responds. Measuremen and analysis for he main measuring circui coninue normally. Measuremen is suspended if a line inerrupion is deeced a erminals L(+) / L(-); he "HM" LED goes off. The sae of he oupu relays "AL" / "VW" and associaed LEDs, he display of he LED-chain and he analogue oupu are "frozen". This Broken wire deecion is signalled by he "ERR" LED flashing wih "Error code 2" and he faul signalling relay responds. Measuremen of he connecion insulaion resisance resars afer he connecion inerrupion has been correced. However, sored alarm messages are preserved. If he connecions PE / KE o he proeciveconducor sysem are inerruped, he same responses ake place as wih an inerrupion a erminals L(+) / L(-), only ha he "ERR" LED indicaes "Error code 3". Device es funcions Principally, 2 differen es funcions are implemened: The "self-es" and he "expanded es": The self-es of he device is performed auomaically afer Power-On and every 4 operaing hours. I can also be riggered manually a any ime by pressing he "Tes" buon a he device fron or wih an exernal pushbuon conneced beween erminals T and G. Wih he self-es, conrary o he expanded es, he saus of he oupu relays and he analogue oupu are no affeced; he sequence is as follows: Swiching o he negaive measuring phase is performed for 4 sec. The "HM" LED flashes here wih a brief On-phase. The LEDs of he LED-chain are seleced in sequence and he inernal circui is checked. Afer his, swiching o he posiive measuring phase is performed for 4 sec. The "HM" LED flashes here wih a long On-phase. The LED-chain cycles again and addiional inernal ess are performed. Insulaion measuremen coninues normally afer a pause of 2 sec if no fauls have occurred. 61

Selecor swich "v / UN" should be se accordingly. For phoovolaic sysems and hybrid vehicles, he main measuring circui of he LK 5896 is conneced on he DC side; he auxiliary measuring circui can hen be used o monior he (deacivaed) AC side. For he main measuring circui, he nominal volage range for DC is specified wih 1000 V; however, absolue values up o max. DC 1500 V are permissible. Only one insulaion monior may be acive in a nework o be moniored, since he devices would oherwise influence each oher. When coupling several neworks or incoming feed secions, where each of hem is equipped wih is own insulaion monior, all of hem mus be deacivaed excep for one insulaion monior. Such deacivaion can be beneficially handled via he HM-G conrol erminals wih he LK The main measuring circui is designed for large leakage capaciances up o 3000 μf. The selecion swich "CE/μF" mus be se accordingly. Measuremen of he insulaion resisances is no falsified by his; however, longer periods are required for he measuring phases han wih small capaciances. If he maximum approximae leakage capaciance is known, he selecor swich "CE/μF" can possibly be se o smaller values, which reduces he response ime furher. The measuring circui should no be conneced via longer parallel guided wires, as his may inerfere wih he broken wire deecion. Also large capaciies beween L(+) und L(-) have o be avoided. No exernal poenials may be conneced o conrol erminals "ZM", "HM", "T" and "R". The associaed reference poenial is "G" (idenical wih PE), and he connecion of he erminals is made via bridges o "G".

Swiching on he auxiliary volage is followed by an inernal selfes for 10 sec, where he LEDs of he indicaor sring ligh up in sequence. Afer his, measuremen of he insulaion resisance in he measuring circuis begins. Measuring circui (Insulaion measuremen beween erminals L(+) / L(-) and PE / KE) Terminals L(+) and L(-) are conneced o he mains o be moniored. Broken wire deecion, consanly effecive during operaion, generaes an error messages if boh erminals are no conneced wih low resisance hrough he mains. In addiion, he wo erminals PE and KE mus be conneced o he proecive conducor sysem via separae lines. An error message is given here as well if a line is inerruped (see secion "Acions in case of connecion fauls"). If he main measuring circui is acivaed (erminal HM open), an acive measuring volage wih alernaing polariy is applied beween L(+) / L(-) and PE / KE o measure he insulaion resisance. During he measuring phase wih posiive polariy, he "HM" LED flashes wih a long On-phase and wih negaive polariy wih a shor On-phase. The "HM" LEDs goes off when he main measuring circui is swiched off hrough bridges of erminals HM-G. Measuremen is suspended and no more measuring volage reaches he measuring circui, so ha in case of coupling o a nework where anoher insulaion monior is already acive, no inerference can occur. The lengh of he posiive and negaive measuring phases depends on he seings on he roary swich "CE/μF", he acual leakage capaciance of he moniored nework and wih DC neworks, on he level and duraion of possible mains volage flucuaions. Correc and preferably quick measuremen is hus given wih differen mains condiions. In he even of paricularly adverse condiions and major inerferences, he measuring analysis can be seadied and delayed in addiion wih roary swich "v" if necessary. The curren insulaion resisance is deermined and analysed a he end of each measuring phase. The LED-chain show he resisance deermined, and he oupu relays for prewarning "VW" and alarm "AL" swich according o he respecive response values se. If he response hresholds have been undercu, he LEDs "VW" or "AL" ligh according o he insulaion faul locaion: "+", "-" or "+" and "-" simulaneously for AC fauls or symmeric insulaion fauls. Soring insulaion faul message If erminal R is open, he insulaion faul messages (relay, LEDs) are sored when he respecive response value is undercu, bu also when he insulaion resisance reurns o he OK-range. In addiion, he emporary minimum values of he insulaion resisance are indicaed on he LEDchain hrough dimmed LEDs. If he "Rese" buon on he device fron is pressed or erminal R is conneced wih G, he sored insulaion faul messages are rese when he insulaion resisance is again in he OK-range. Flashing Codes LED "ERR" inernal device error connecion error L+/L- connecion error PE/KE M084 Oupu relay for insulaion faul messages The roary swich "CE/μF Rel." allows selecing he open circui (A) or closed circui (R) operaion for he oupu relays "AL" (conacs ) and "VW" (conacs ). Wih he open circui operaion, he relays respond when he response values are undercu, wih he closed circui operaion hey release when he response values are undercu. If 2 differen response values are no needed, "VW" and "AL" can be se o he same value. The oupu relays swich ogeher in his case ( 2u ). Broken wire deecion As menioned above, all erminals of he measuring circui are consanly moniored for wire breaks - no only a Power-On or a manual or occasional auomaic es. The response ime of monioring is only a few seconds. Broken wire deecion beween L(+) and L(-) is performed via coupled alernaing volage. This alernaing volage is shor-circuied if he erminals are conneced o he conneced mains a low-resisance. The device deecs ha he mains o be moniored is properly conneced. Since his broken wire deecion is carried ou wih alernaing volage, large capaciances should be avoided beween L(+) and L(-), since he capaciive reacance of hese capaciances also shor-circuis his alernaing volage. The device would no longer deec a connecion faul on L(+)/L(-). Especially parallel lines should be prevened over larger disances. If larger capaciances beween L(+)/L(-) canno be avoided or if he coupled alernaing volage inerferes wih he sysem, version LK /0 (wihou broken wire deecion on L(+)/L(-) ) shall be used. 67

59 Funcion Device es funcions Principally, 2 differen es funcions are implemened: The "self-es" and he "expanded es": The self-es of he device is performed auomaically afer Power-On and every 4 operaing hours. I can also be riggered manually a any ime by pressing he "Tes" buon a he device fron or wih an exernal pushbuon conneced beween erminals T and G. Wih he self-es, conrary o he expanded es, he saus of he oupu relays and he analogue oupu are no affeced; he sequence is as follows: Swiching o he negaive measuring phase is performed for 4 sec. The "HM" LED flashes here wih a brief On-phase. The LEDs of he LED-chain are seleced in sequence and he inernal circui is checked. Afer his, swiching o he posiive measuring phase is performed for 4 sec. The "HM" LED flashes here wih a long On-phase. The LED-chain cycles again and addiional inernal ess are performed. Insulaion measuremen coninues normally afer a pause of 2 sec if no fauls have occurred. The expanded es is sared when he inernal or exernal "Tes" buon is pressed (or is sill held) a he end of he 8 sec self-es, described above. The sequence is he same as wih he self-es (2 measuring phases a 4 sec + 2 sec pause); however, he oupu relays "AL" and "VW" as well as he associaed LEDs swich o he alarm sae and he analogue oupu proceeds o is lowes value. If he Rese buon is pressed during he 8 sec or erminals R-G are conneced, he expanded es is erminaed afer hese 8 sec. Oherwise, he phases of he expanded es are consanly repeaed, where, in addiion, he "ERR" LED is on. However, he expanded es is erminaed as soon as he Rese buon is pressed. The device swiches o he OK-sae and resars insulaion measuremen. Behaviour wih inernal device fauls If inernal device fauls were deeced during he es funcion, he "ERR" LED is li coninuously and he measuring circui is deacivaed inernally ("HM" LED goes off). The oupu relays "AL" and "VW" as well as he associaed LEDs swich o he alarm sae and all LEDs of he LED-chain exinguish. Behaviour in he case of connecion fauls If broken wire is deeced on erminals L(+) / L(-), he measuremen is inerruped and he LED "HM" goes off. This connecion failure is indicaed by LED "ERR" wih "failure code 2". The oupu relays "AL" and "VW" as well as he corresponding LEDs go ino alarm sae and all LEDs of he indicaor LED chain go off. Afer removing he he inerrupion he measuremen of he insulaion resisance sars again. Sored alarm saes remain acive. When inerruping he connecion PE / KE o he proecive ground, he uni reacs in he same way as wih an inerrupion on L(+) / L(-), only he LED "ERR" shows "failure code 3".

The measuring circui can be conneced wih is erminals L(+) and L(-) boh o he DC and also AC side of a mixed nework; i is done mos pracically where he primary incoming power supply akes place. Selecor swich "v / U N " should be se accordingly. For phoovolaic sysems and hybrid vehicles, he measuring circui of he LK 5895 is conneced on he DC side; he auxiliary measuring circui can hen be used o monior he (deacivaed) AC side. For he main measuring circui, he nominal volage range for DC is specified wih 1000 V; however, absolue values up o max. DC 1500 V are permissible. Only one insulaion monior may be acive in a nework o be moniored, since he devices would oherwise influence each oher. When coupling several neworks or incoming feed secions, where each of hem is equipped wih is own insulaion monior, all of hem mus be deacivaed excep for one insulaion monior. Such deacivaion can be beneficially handled via he HM-G conrol erminals wih he LK The measuring circui is designed for large leakage capaciances up o 3000 μf. The selecion swich "CE/μF" mus be se accordingly. Measuremen of he insulaion resisances is no falsified by his; however, longer periods are required for he measuring phases han wih small capaciances. If he maximum approximae leakage capaciance is known, he selecor swich "CE/μF" can possibly be se o smaller values, which reduces he response ime furher. The measuring circui should no be conneced via longer parallel guided wires, as his may inerfere wih he broken wire deecion. Also large capaciies beween L(+) und L(-) have o be avoided. No exernal poenials may be conneced o conrol erminals, "HM", "T" and "R". The associaed reference poenial is "G" (idenical wih PE), and he connecion of he erminals is made via bridges o "G". Aenion!!

Swiching on he auxiliary volage is followed by an inernal selfes for 10 sec, where he LEDs of he indicaor sring ligh up in sequence. Afer his, measuremen of he insulaion resisance in he measuring circuis begins. Measuring circui (Insulaion measuremen beween erminals L(+) / L(-) and PE / KE) Terminals L(+) and L(-) are conneced o he mains o be moniored. Broken wire deecion, consanly effecive during operaion, generaes an error messages if boh erminals are no conneced wih low resisance hrough he mains. In addiion, he wo erminals PE and KE mus be conneced o he proecive conducor sysem via separae lines. An error message is given here as well if a line is inerruped (see secion "Acions in case of connecion fauls"). If he main measuring circui is acivaed, an acive measuring volage wih alernaing polariy is applied beween L(+) / L(-) and PE / KE o measure he insulaion resisance. During he measuring phase wih posiive polariy, he "Acive" LED flashes wih a long On-phase and wih negaive polariy wih a shor On-phase. The lengh of he posiive and negaive measuring phases depends on he seings on he roary swich "CE/μF", he acual leakage capaciance of he moniored nework and wih DC neworks, on he level and duraion of possible mains volage flucuaions. Correc and preferably quick measuremen is hus given wih differen mains condiions. In he even of paricularly adverse condiions and major inerferences, he measuring analysis can be seadied and delayed in addiion wih roary swich "v" if necessary. The curren insulaion resisance is deermined and analysed a he end of each measuring phase. The LED chain show he resisance deermined, and he oupu relays for prewarning "VW" and alarm "AL" swich according o he respecive response values se. If he response hresholds have been undercu, he LEDs "VW" or "AL" ligh according o he insulaion faul locaion: "+", "-" or "+" and "-" simulaneously for AC fauls or symmeric insulaion fauls. Soring insulaion faul message If erminal R is open, he insulaion faul messages from he main and auxiliary measuring circui are sored when he respecive response value is undercu, bu also when he insulaion resisance reurns o he OK-range.

The response ime of monioring is only a few seconds. Broken wire deecion beween L(+) and L(-) is performed via coupled alernaing volage. This alernaing volage is shor-circuied if he erminals are conneced o he conneced mains a low-resisance. The device deecs ha he mains o be moniored is properly conneced. Since his broken wire deecion is carried ou wih alernaing volage, large capaciances should be avoided beween L(+) and L(-), since he capaciive reacance of hese capaciances also shor-circuis his alernaing volage. The device would no longer deec a connecion faul on L(+)/L(-). Especially parallel lines should be prevened over larger disances. If larger capaciances beween L(+)/L(-) canno be avoided or if he coupled alernaing volage inerferes wih he sysem, version LK /0 (wihou broken wire deecion on L(+)/L(-) ) shall be used. 72

64 Funcion Device es funcions Principally, 2 differen es funcions are implemened: The "self-es" and he "expanded es": The self-es of he device is performed auomaically afer Power-On and every 4 operaing hours. I can also be riggered manually a any ime by pressing he "Tes" buon a he device fron or wih an exernal pushbuon conneced beween erminals T and G. Wih he self-es, conrary o he expanded es, he saus of he oupu relays and he analogue oupu are no affeced; he sequence is as follows: Swiching o he negaive measuring phase is performed for 4 sec. The Acive LED flashes here wih a brief On-phase. The LEDs of he LED chain are seleced in sequence and he inernal circui is checked. Afer his, swiching o he posiive measuring phase is performed for 4 sec. The Acive LED flashes here wih a long On-phase. The LED chain cycles again and addiional inernal ess are performed. Insulaion measuremen coninues normally afer a pause of 2 sec if no fauls have occurred. The expanded es is sared when he inernal or exernal "Tes" buon is pressed (or is sill held) a he end of he 8 sec self-es, described above. The sequence is he same as wih he self-es (2 measuring phases a 4 sec + 2 sec pause); however, he oupu relays "AL" and "VW" as well as he associaed LEDs swich o he alarm sae and he analogue oupu proceeds o is lowes value. If he Rese buon is pressed during he 8 sec or erminals R-G are conneced, he expanded es is erminaed afer hese 8 sec. Oherwise, he phases of he expanded es are consanly repeaed, where, in addiion, he "ERR" LED and he faul signalling relay (conacs ) consanly receive curren. However, he expanded es is erminaed as soon as he Rese buon is pressed. The device swiches o he OK-sae and resars insulaion measuremen. Behaviour wih inernal device fauls If inernal device fauls were deeced during he es funcion, he "ERR" LED is li coninuously and he measuring circui is deacivaed inernally ("Acive" LED goes off). The oupu relays "AL" and "VW" as well as he associaed LEDs swich o he alarm sae and all LEDs of he LED chain exinguish. Behaviour in he case of connecion fauls If broken wire is deeced on erminals L(+) / L(-), he measuremen is inerruped and he LED "HM" goes off. This connecion failure is indicaed by LED "ERR" wih "failure code 2". The oupu relays "AL" and "VW" as well as he corresponding LEDs go ino alarm sae and all LEDs of he indicaor LED chain go off. Afer removing he he inerrupion he measuremen of he insulaion resisance sars again. Sored alarm saes remain acive. When inerruping he connecion PE / KE o he proecive ground, he uni reacs in he same way as wih an inerrupion on L(+) / L(-), only he LED "ERR" shows "failure code 3". Noes Device erminals PE and KE mus always be conneced via separae lines o differen erminal poins of he proecive-conducor sysem. The main measuring circui can be conneced wih is erminals L(+) and L(-) boh o he DC and also AC side of a mixed nework; i is done mos pracically where he primary incoming power supply akes place. Selecor swich "v / U N " should be se accordingly. For he main measuring circui, he nominal volage range for DC is specified wih 690 V; however, absolue values up o max. DC 1000 V are permissible. In one volage sysem o be moniored, only one insulaion monior mus be insalled. A second insulaion monior would influence he firs one. When coupling separae volage sysems ha each have an insulaion monior, all insulaion moniors excep one have o be disabled. The main measuring circui is designed for large leakage capaciances up o 1000 μf. The selecion swich "CE/μF" mus be se accordingly. Measuremen of he insulaion resisances is no falsified by his; however, longer periods are required for he measuring phases han wih small capaciances. If he maximum approximae leakage capaciance is known, he selecor swich "CE/μF" can possibly be se o smaller values, which reduces he response ime furher. The measuring circui should no be conneced via longer parallel guided wires, as his may inerfere wih he broken wire deecion. Also large capaciies beween L(+) und L(-) have o be avoided. No exernal poenials may be conneced o conrol erminals "T" and "R". The associaed reference poenial is "G" (idenical wih PE), and he connecion of he erminals is made via bridges o "G". Aenion!!

99 Funcion Swiching oupu The device is equipped wih a ransisor swiching oupu (erminals G, H), which is proeced by a series-conneced PTC (RN = 220 ). In he idle sae, he oupu is high-resisance. During insulaion faul deecion, he oupu is low-resisance (RN) and delivers a low-level in conjuncion wih a series resisor and an exernal volage source. RS-485 bus connecion The insulaion faul locaor RR 5887 generally works in slave mode. I synchronises iself independenly wih he es curren oupu by monioring he RS485 elegram. All conneced insulaion faul locaors RR 5887 work in parallel and independenly from each oher. A bus address can be defined for he device via a roary swich (RS-485 Bus). If he devices are inegraed in an EDS measuring bus sysem for insulaion faul deecion, i mus be remembered ha each insulaion faul locaor receives is own channel number. An EDS measuring bus maser can read insulaion faul curren values from he conneced devices via his channel number. The bus address of he associaed locaing curren injecor RR 5886 can be se via anoher roary swich (RR 5886 Channel). A unique reference beween a locaing curren injecor and one or several insulaion faul locaors is esablished here. This way, several device combinaions can be conneced joinly o a RS-485 bus and monior separae neworks. In he absence of an EDS measuring bus connecion, he bus address does no have any special significance and be chosen arbirarily. The RS-485 LED is permanenly on during he insulaion faul deecion and bus aciviy and flashes when bus failures occur. Influence of discharge capaciies The insulaion faul locaor is also able o perform reliable measuremens under he influence of discharge capaciies up o a cerain size. The influence of discharge capaciies depends on he insulaion resisance and he mains volage. Reliable deecion of insulaion resisance is ensured up o a discharge capaciy of 1 μf. The lower he mains volage, he greaer he permissible discharge capaciy may be. For example, wih mains volages of 50 V, 20μF and more can also be processed wihou problem. Insulaion faul deecion is no longer possible if he influence of he discharge capaciies becomes oo grea. The measuring resul may become poorer, in addiion, when he discharge capaciies are disribued unevenly in he nework. However, he symmery relaionships of he insulaion faul resisances hemselves do no affec he qualiy of he measuremen. If insulaion fauls are presen beween several conducors and PE, mains compensaion currens flow hrough he insulaion faul resisances overlaying he acual insulaion faul currens. The measured insulaion faul curren can be reduced by half here in he exreme case. Curren ransformer calibraion Curren ransformer calibraion is performed afer swiching on he device or afer pushing he "Alarm rese/ Tes/ Transformer calibraion" pushbuon o compensae olerances of he magneic maerial of he curren ransformers and he resuling differences of he magneic amplificaion. Insulaion faul measuremen in mixed neworks If an alernaing curren nework, conaining a downsream recifier, is moniored, insulaion faul deecion can also be performed in he direc volage circui if he discharge capaciies in his circui are no oo high. Because faul deecion can be performed simulaneously in wo differen nework forms alernaing curren nework and direc curren nework he indicaions displayed for prewarning and alarm are quaniaively valid only for he nework form se wih he roary swich. The nework form no se will deliver resuls deviaing by he facor 2. However, hey can sill be analysed in erms of heir endency, i.e. a poenial insulaion faul is sill indicae. Insulaion faul curren display The locaing curren injecor akes he power for he es curren from he moniored nework iself. Insulaion faul curren measuremens are nearly idenical boh for AC and DC neworks.

129 Funcions Indicaor In 3-phase sysems all hree phases are measured agains neural. In he monioring modes overvolage, undervolage and volage range he excess of he swiching volage U by one or more phase volages is indicaed by blinking of he corresponding LED. Afer he swiching delay ime has expired he volage LED is on permanenly and he oupu relay releases. If he phase volage which has riggered he alarm falls below he nominal volage U, he volage LED swiches off immediaely whereas he oupu relay is energized. The oupu relay operaes in closed circui mode i.e. in case of good condiion he relay energized whereas in faul condiion i is de-energized. In he volage range monioring mode he nominal volage range U ± U is adjusable. An alarm is riggered in case a phase volage leaves his monioring range. The hyseresis for swiching back ino good condiion is half he value se by he poeniomeer U. In he volage monioring operaion modes an excess of he volage asymmery beween he hree phases of more han 25 % is indicaed by he asymmery LED urning on. In his erminology asymmery means he relaive difference of he maximum phase volage and he minimum phase volage. Fall back ino good condiion occurs wih a hyseresis of ca. 6 %. In his case he asymmery LED urns off and he oupu relay energizes. In he asymmery monioring operaion mode he rigger level for asymmery excess in 3-phase sysems is adjusable. The hyseresis for falling back ino good condiion is exacly half of he se value for asymmery. In his monioring mode acivaion and deacivaion of he oupu relay is done using he same iming parameers as in he volage monioring mode excep ha he conrol is governed by asymmery excess raher han volage excess. In his funcion mode a difference of he phase volage o he adjused volage value of more hen 25% is indicaed by he corresponding volage LED. Again fall back ino good condiion is done wih a hyseresis of approx. 6 %. In all monioring modes of a 3-phase sysem a correc phase sequence is moniored. In case of a wrong phase sequence he phase sequence LED urns on permanenly and he oupu relay remains de-energized. This sae is on hold unil he uni is resared wih correc phase sequenze. Afer he phase sequence is correc again he LED is urned off immediaely. green LED ON : red LED U : red LED <U : yellow LED Asym. : yellow LED L2 L3 : on, when supply conneced on, when overvolage on, when undervolage indicaes a volage asymmery in 3-phase sysems or loss of neural indicaes wrong phase sequence in 3-phase sysems or loss of neural Varian /120: green LED ON : on, when supply conneced red LED : on, when phase failure a phase 1 red LED L2 : on, when phase failure a phase 2 red LED L3 : on, when phase failure a phase 3 yellow LED L2 L3 : indicaes wrong phase sequence in 3-phase sysems Noes During iniialisaion he relay recognises auomaic he mains frequency (50 Hz or 60 Hz) and Nezform (3AC- or 1AC- sysems).

In 3-phase sysems wihou neural he dela volages UA, UB and UC are calculaed via virual sar volages by means of vecor addiion. The monioring modes are he same as wih devices wih neural. The following relaionships beween riangle volages and device erminals are o be aken ino accoun: UA = - L2; UB = L3; UC = L2 L3; The varian RN9877/120 is especially suiable o deec phase failures. While he neural is conneced and a phase drops under 50% of he phase volage he corresponding LED signals he failure. The percenage beween minimum and maximum phase volage is measured. When he neural is missing, he phases are measured in relaion o a virual inernal neural. Afer elaps of he swiching delay he phase failure LED is coninuously on and he oupu relay swiches off (de-energised on rip).

The AC unis are adjused o he r.m.s value. They have seings for response value and hyseresis. The unis work as overcurren relays bu can also be used for undercurren deecion. The hyseresis is dependen on he response value. 2 ime delays are possible in differen varians: The sar up delay a operaes only when connecing he auxiliary supply. I disables ripping e.g. caused by an increased saring curren of a moor. The response delay v is acive afer exceeding a response value. On overcurren relays he delay is acive when he curren goes over he ripping value, on undercurren relays when he curren drops below he hyseresis value.

253 Noes Technical Daa To erminal X1 only he poenial of /i mus be conneced. When seing he response value on BA 9065 wih frequency converers please noe ha he cos ϕ of he moor changes wih he frequency. The measuremen of he cos ϕ is made by deecing he phase angle beween curren and volage by monioring he shif of he zero passage of curren and volage.

When using he model BA 9065./001 wih separae auxiliary supply, he measuring circui (/i-/k; L2-L3) can also monior variable frequencies and volages on he oupu of a frequency converer.

318 Funcions The auxiliary supply is conneced o erminals A1-A2. Terminals E0-E1-E2 form he measuring inpu. For low volages he measuring volage is conneced o E1-E0 and for higher volages o E2- E0 (see secion echnical daa). The inpu frequency is compared o he seing value (response value = fine unig x range). As he device measures he cycle duraion he fases frequency measuremen is possible (reacion ime = cycle ime + 10 ms). In overfrequency mode (swich on fron in pos. >f ) he oupu relay swiches o alarm sae if he inpu frequency rises above he response value for a longer ime hen seleced on he erminals. If he measuring frequency drops again under he hyseresis value, he oupu relay swiches back o good sae wihou delay. In underfrequency mode (swich on fron in pos. <f ) he oupu relay swiches o alarm sae, if he inpu frequency drops below he response value for a longer ime hen seleced on he erminals. If he measuring frequency rises again above he hyseresis value, he oupu relay swiches back o good sae wihou delay. If manual rese is chosen, he oupu relay says in ripped posiion, even if he frequency is back o normal. The rese is made by bridging erminals X2-M or by disconnecing he auxiliary supply. In alarm sae he yellow LEDs R1 / R2 are coninuously on, during ime delay hey flash wih shor pulse. In de-energized on rip mode he oupu relay is energized in good sae (conacs -14 ec. closed). In energized on rip mode he oupu relay is energized in alarm sae (conacs -14 ec. closed). If sar up delay is seleced a imer is sared afer connecion of auxiliary supply ha disables he measuring circui for he adjused ime. This sar up delay avoids an alarm e.g. when saring a generaor or moor. When measuring overfrequency, monioring of he signal on E0-E1-E2 can be seleced. If he signal is missing longer hen he seleced monioring ime, relay 2 (conacs ) and LED R2 indicae alarm. Indicaors Upper LED UH/E : - green, when only auxiliary volage conneced o A1 - A2 - yellow/green, when measuring frequency is deeced on E0-E1-E2 Lower LED R1 (yellow): - On, when alarm sae (under- / overfrequency) flashes (wih shor pulse) when ime delay is acive Lower LED R2 (yellow): - On, when alarm sae (under- / overfrequency) flashes (wih shor pulse) when ime delay is acive - addiional flashes a signal monioring alarm LEDs "R1" and "R2" flash ogeher during sar up delay Noes Frequency measuring inpu The sandard measuring inpu is divided up in o volage ranges (E1-E0 AC V and E2-E0 AC V). If he measuring volage is always higher hen AC 30 V, he higher range should be used. To measure he oupu frequency on inverers he varian /_5_ has o be used. A special dimensioned measuring inpu wih low pass characerisic avoids he measuring of he pulse frequency. In addiion he inpu sensiiviy is adaped o he volage-/frequency-characerisic of inverers (see diagram in echnical daa). Visual indicaion of measuring volage: If he volage on he measuring inpu is o low for correc funcion on inpus E0-E1-E2 he upper 2-colour LED UH/E shows green coninuous ligh. If underfrequency is seleced he uni indicaes underfrequency alarm, if overfrequency is seleced ogeher wih measuring signal monioring he uni indicaes measuring signal alarm. If he volage on he measuring inpu is high enough he LED UH/E flashes yellow/green. Noes Sar up delay / monioring of measuring signal. The sar up ime delay (A) can be adjused wih he lowes poeniomeer on he fron side of he uni and is acivaed when connecing he auxiliary supply. In underfrequency mode ( <f ) he sar up delay can be exended/resared a any ime wih a conrol conac beween erminals X3-M. As long as X3-M is bridged he sar up delay is coninuously on and he frequency is no measured. When he link on X3-M is opened he sar up delay ime resars. In overfrequency mode ( >f ) wih a bridge on X3-M, he lowes poeniomeer ses he measuring signal monioring ime (S) (The adjused ime values A/S are idenically). When signal monioring in mode >f is seleced by bridging X3-M he measuring inpu is moniored as follows: If during he adjused monioring ime inerval no measuring signal is deeced, measuring signal alarm is indicaed. As soon as he measuring signal reurns he alarm saus is rese (auo rese seleced) and he monioring inerval S sars again. The alarm saus is indicaed on relay 2 (conacs ) and LED R2 and can be easily differeniaed from under/over frequency alarm where boh relays (conacs and ) and LEDs R1 and R2 ) are acive. The deecion of missing measuring signal can increase he safey in criical applicaions on overfrequency. I deecs if he measuring signal is conneced o he inpu of he device and works correcly Programming erminals (M-X1-X2-X3): Aenion! The erminals M-X1-X2-X3 have no galvanic separaion o he measuring circui, and mus be operaed poenial free. M: Common connecion (Ground) of he programming erminals X1: A response delay of s afer connecion of auxiliary supply is achieved by connecing a X1 o M wih a poeniomeer or fixed resisor (see echnical daa). The delay can be sopped by bridging X1 o M a any ime. If no sar up delay is required he erminals X1-M mus be linked. X2: Manual rese wih NO conac push buon on X2-M, auo rese wih erminals X2-M bridged. X3: When X3-M is bridged in mode underfrequency he sar up delay is coninuously acive or he ime is resared. In mode overfrequency he monioring of he measuring signal is swiched on by bridging X3-M. Adjusmen aid for sar up delay and alarm delay During he elapse of sar up delay and alarm delay he yellow LED R1 and R2 is flashing wih a frequency of 2 Hz. To se a specific ime value in seconds he number of flash pulses can be used o check he seing: Number of flash pulses divided by 2 = ime delay in seconds. Varian MH /008: 45 mm widh Idenically o MK 9837N.12, bu wih sep LED chain indicaor and galvanic separaed analogue oupu o display he acual measured frequency. On erminals U/G of he analogue oupu 0-10 V are provided, on erminals I/G 0-20 ma are available. By bridging erminals Y1 and G he oupu can be swiched over o 2-10 V and 4-20 ma. The max. value of he analogue oupu is indicaing 2 imes of he max. value of he seleced range his allows also o indicae overfrequency values. The scaling is linear o he inpu frequency (lowes analogue value is 0 Hz). The LED chain indicaor shows on 10 LEDs he acual frequency ( 10% % of he seing range). If he frequency exceeds he maximum value of he range he idicaor is swiched over o 2 x max value and he op LED (red) is on. 327

The inpu frequency is compared o he seing value for over- and underfrequency (response value f1 e.g. f2 = fine unig x range). As he device measures he cycle duraion he fases frequency measuremen is possible (reacion ime = cycle ime + 10 ms). If he inpu frequency on he measuring inpu E0-E1-E2 is under he response value f1 less hyseresis (boh upper poeniomeers) and over he response value f2 (boh lower poeniomeers) plus hyseresis hen he oupu relays are energized and he yellow LEDs <f1 and >f2 are on.

If f2 is used for overfrequency, he uni works energized on rip, as he relay 2 ( ) always energizes when he frequency rises above response value + hyseresis. In he same way he response value f1 - hyseresis can be used for underfrequency so ha relay 1 (-12-14) is energized on rip. When using manual rese in window mode he response value f1 (minus hyseresis) mus always be higher han f2 (plus hyseresis) o avoid ha he oupu relays do no swich anymore and he yellow LEDs <f1 and >f2 remain dark.

360 Noes Technical Daa To he universal inpu of he speed monior (erminals +U, X1, IN, 0V) a wide range of differen sensors can be conneced (capaciive, inducive, ulrasonic, hall effec, opical, reed, ec.) The inpu is suiable for proximiy sensors according o IEC/EN (VDE 0660 par 208) Depending on he ype of sensor (3-wire PNP or NPN, 2-wire, conac, volage) he connecion is made o differen erminals (see Connecion Examples). The models IL and SL 9144 have a galvanic separaion beween Inpu Circui (+U, X1, IN, 0V) and auxiliary supply (A1, A2 e.g. 230VAC). 24V DC wih up o 20mA is provided on he erminals U+/0V for he supply of he sensor. If sensors wih higher power consumpion are used, he model IK and SK 9144 is suiable, where he sensors and he speed monior is supplied by DC 24V from an exernal power supply. The speed moniors can be operaed wih SKF sensor bearings. Sensor bearings include ball bearing and speed sensor in a compac way. The acual sensors are hall effec sensors wih NPN oupu. The connecion is made as wih NPN proximiy sensors. The model /200 is opimised for Namur proximiy sensors according o IEC/ EN (VDE 0660 par 212). Namur sensors are 2-wire sensors wih defined curren in on and off sae. Monioring indicaor of sensor inpu The upper 2-coloured LED shows indicaes he conneced supply volage and he saus of he sensor: Green: inpu IN on LOW level Red: inpu IN on HIGH level Green/Red: pulses on inpu IN Several devices on one sensor A parallel connecion of several moniors o one sensor is possible wihou problems on he universal inpu, when several ripping values are required or a range beween o limis should be moniored. The corresponding erminals are conneced in parallel. Reacion ime The reacion ime is equal o he adjused monioring ime v. To shoren he reacion ime he number of incoming pulses should be increased, e. g. by adding sensing poins o a roaing par. The monioring ime hen can be adjused shorer. Maximum inpu frequency, minimum pulse and space ime Every frequency measuring device deecs inpu pulses only up o a cerain maximum inpu frequency. (This is also a resul of a proper inerference suppression). If he inpu frequency is higher hen he maximum value, he inpu pulses are no longer deeced, i.e. he monior deecs frequency 0. The maximum frequency is always much higher hen he maximum seing value of he highes seing range Also he maximum swiching frequency of he sensors mus be observed. In addiion every frequency inpu needs a cerain minimum pulse and space duraion of he conneced sensor o reac properly. This is very imporan wih high frequency and a low or high pulse/space raio (e. g. a small acive area on big diameer or a small gap on big diameer a high roaion speed). The minimum pulse or space imes are very shor on hese modules, so ha mos applicaions are uncriical (see echnical daa).

Wih a proximiy sensor he speed is convered o a speed proporional frequency. This frequency is compared o an inernal adjusable frequency reference. If he measured frequency is higher hen he reference he oupu relay is energized on an underspeed monior or de-energized on an overspeed monior. The oupu relay deenergises on an underspeed monior if he speed goes under he seed hyseresis value. On he overspeed monior he relay is energized.

The inpu is suiable for proximiy sensors according o IEC/EN (VDE 0660, par 208). Depending on he ype of sensor (3-wire PNP or NPN, 2-wire, conac, volage) he connecion is made o differen erminals (see Connecion Examples). The models IL and SL 9055 have a galvanic separaion beween Inpu Circui (+U, X1, IN, 0V) and auxiliary supply (A1, A2 e.g. 230 V AC). 24 V DC wih up o 20 ma is provided on he erminals U+/0V for he supply of he sensor. If sensors wih higher power consumpion are used, he model IK and SK 9055 is suiable, where he sensors and he speed monior are supplied by DC 24 V from an exernal power supply. The speed moniors can be operaed wih SKF sensor bearings. Sensor bearings include ball bearing and speed sensor in a compac way. The acual sensors are hall effec sensors wih NPN oupu. The connecion is made as wih NPN proximiy sensors. The model /200 is opimised for Namur proximiy sensors according o IEC (VDE 0660 par 212, previously EN / DIN ). Namur sensors are 2-wire sensors wih defined curren in on and off sae. The model /300 is designed o connec permanen magne sensors. Permanen sensors are simple, robus 2-wire sensors wihou volage supply and elecronic circuis. They generae an induced volage while he permanen magne passes. They are very cos effecive and can be used also wih high emperaure and hard ambien condiions.

The corresponding erminals are conneced in parallel. Monioring funcion over- or underfrequency The funcion can be changed by a slide swich on he fron of he uni. Energized on rip or de-energized on rip remains he same when changing he funcion, also he ripping value remains unchanged. No calculaions wih hyseresis are necessary. Hyseresis seing When he seing value is very low in he lowes range, he hyseresis should no be adjused o he minimum in order o avoid cycling of he oupu relay. In he operaing mode underfrequency (<f) a seing values near o he end of he rage he hyseresis can only be se o % due o he inernal circui. When here are problems, he nex higher range should be seleced. Reacion ime The uni work wih an inegraing measuring principle, where he mean value of several inpu pulse periods is calculaed. This avoids problems wih inerference pulses, bu he reacion ime ges longer. The reacion ime relaes o he lowes adjusable frequency on he acual uni.

If he inpu frequency before he change is near o he swiching value or he change of he frequency is very low, he reacion ime can be shorer hen he ime consan. The echnical daa will show always he ime consan. Special models wih shorer ime consan (limied frequency range) on reques. +U 0V X1 Maximum inpu frequency, minimum pulse and space ime Every frequency measuring device deecs inpu pulses only up o a cerain maximum inpu frequency. (This is also a resul of a proper inerference suppression.) If he inpu frequency is higher hen he maximum value, he inpu pulses are no longer deeced. The monior deecs frequency 0. The maximum frequency is always much higher hen he maximum seing value of he highes seing range (see echnical daa). Also he maximum swiching frequency of he sensors mus be observed. In addiion every frequency inpu needs a cerain minimum pulse and space duraion of he conneced sensor o reac properly. This is very imporan wih high frequency and a low or high pulse/space raio (e.g. a small acive area on big diameer or a small gap on big diameer a high roaion speed). If a frequency near o he maximum speed should be deeced a pulse/space raio of 1:1 should be provided by designing he roaing par accordingly. Pulse ime is he ime he high signal is presen a e IN erminal, space ime is he ime he low signal is presen on he IN erminal. When using PNP sensors or conacs conneced o +U he pulse ime is idenically wih he on ime of he sensor or conac. The minimum pulse or space ime are very shor on hese modules, so ha mos applicaions are uncriical (see echnical daa).

374 Funcion The auxiliary supply is conneced o erminals A1-A2. An operaion wih alernaively DC 24 V is possible via erminals +U / 0V. Differen sensors can be conneced o he measuring inpu ha deecs he speed pulses. The inpu frequency is compared o he seing value (response value = fine unig x range). As he device measures he periods duraion he fases frequency measuremen is possible. In overfrequency mode (swich on fron in pos. >f ) he oupu relays swiches o alarm sae if he inpu frequency rises above he response value for a longer ime hen seleced on he erminals. If he measuring frequency drops again under he hyseresis value, he oupu relay swiches back o good sae wihou delay. In underfrequency mode (swich on fron in pos. <f ) he oupu relays swiches o alarm sae, if he inpu frequency drops below he response value for a longer ime hen seleced on he erminals. If he measuring frequency rises again above he hyseresis value, he oupu relay swiches back o good sae wihou delay. If manual rese is chosen, he oupu relay says in ripped posiion, even if he frequency is back o normal. The rese is made by bridging erminals X2-M or by disconnecing he auxiliary supply. In alarm sae he yellow LEDs R1 / R2 are coninuously on, during ime delay hey flash wih shor pulse. In de-energized on rip mode he oupu relay is energized in good sae (conacs -14, ec. closed). In energized on rip mode he oupu relay is energized in alarm sae (conacs -14, ec. closed). If sar up delay is seleced a imer is sared afer connecion of auxiliary supply ha disables he measuring circui for he adjused ime on erminal X3. During his ime he frequency measuremen is disabled, he yellow LEDs "R1" and "R2" flash symmerically and he oupu relays remain in good posiion. This sar up delay avoids an alarm e.g. when saring a generaor or moor. IIn overfrequency mode missing inpu signal can be moniored as opion: If he signal is missing longer hen he seleced monioring ime, relay 2 (conacs ) and LED R2 indicae alarm. The varian /010 (NAMUR sensor inpu) includes broken wire and shor circui monioring of he sensor and connecion wire. A red LED indicaes his failure and he oupu relays swich off. Indicaors Upper LED "UH/E": - green: Auxiliary supply is presen, measuring inpu is Low - yellow: Auxiliary supply is presen, measuring inpu is High - linermien red/green flashing if U H and impuls sequence presen Red LED "Sen.Err": (only a NAMUR inpu) - on, when broken wire or inerrupion a sensor cirui deeced Lower LED R1 (yellow): - on, when alarm sae (under- / overfrequency) flashes (wih shor pulse) when ime delay is acive Lower LED R2 (yellow): - on, when alarm sae (under- / overfrequency) flashes (wih shor pulse) when ime delay is acive - addiional flashes a signal monioring alarm LEDs "R1" and "R2" flash ogeher during sar up delay Noes Universal measuring inpu The universal inpu of he speed monior (erminals +U, P, E, 0V) can handle a large variey of sensors (inducive or capacive proximiy sensors, ulra sonic, halleffec, opical sensors, ligh barriers, reed conacs ec.). The inpu is suiable for all sensors according o IEC / EN (VDE 0660 par 208). Depending on he sensor ha is used (3-wire PNP or NPN, 2-wire, conac) he connecion o he inpu erminals could be differen (see Connecion Examples). As he speed monior is suiable for a very high maximum frequency, RCelemens need o be insalled o suppress bouncing of conac sensors (see Connecion Examples). I is possible o use sandard RC-elemens suiable for conac proecion or RF inerference proecion. NAMUR inpu The Varian M_ 9055N/010 is opimzed for he connecion of NAMUR sensors according o IEC / EN (VDE 0660 Teil 212; former EN / DIN 19234). These 2-wire-sensors are conneded o erminals IN+ / IN- (see applicaion example). Namur sensors have a defined curren in ON as well as in OFF sae. This allows o deec shor circuis and broken wire on sensor and connecion wires wih his varian. Togeher wih he upper green/yellow LED he ype of failure is indicaed: Red LED "Sen..Err" ON and upper LED "UH/E" lighs up green: Broken wire a inpu circui Red LED "Sen..Err" ON and upper LED "UH/E" lighs up yellow: Shor circui a inpu circui Insead of a NAMUR sensor also a conac sensor wih corresponden resisor circui can be used (see Connecion Examples).The suggesed resisors are necessary o avoid broken wire or shor circui deecion alarm. If he resisors are conneced direcly on he sensor side, he wiring sill is moniored. Because of conac bouncing of mechanical conacs a capacior has o be conneced on he measuring inpu erminals. Sensor supply, 24V DC auxiliary supply as alernaive The inpu circui (+U, P, E, 0V) is galvanic separaed o he auxiliary supply A1, A2 (eg. AC 230V). By connecing AC 230V auxiliary volage on erminals A1-A2 he uni provides a volage of approx. 24 V max 20mA o supply exernal sensors. If he auxiliary supply is DC 24V or sensors wih higher power consumpion are used, he DC 24V auxiliary supply is conneced o erminals +U / 0V. The sensors are also supplied from his source. (In his case here is no galvanic separaion beween auxiliary supply and measuring inpu). Monioring indicaor of sensor inpu The upper 2-coloure LED shows he conneced supply volage and he elecrical sae of he measuring inpu: Green: inpu E is on LOW level Yellow: inpu E ion HIGH level Depending on he ype of sensor (PNP, NPN, 2-wire, NO or NC conac) he acual sae (acive or inacive) is indicaed. Green / yellow: inpu pulses from sensor presen Several speed moniors on one sensor Parallel operaion of several speed moniors on one sensor is possible he universal inpu e.g. o monior several speed levels. The corresponding erminals are all conneced in parallel. Sar up delay / monioring of measuring signal. The sar up ime delay ( A ) can be adjused wih he lowes poeniomeer on he fron side of he uni and is acivaed when connecing he auxiliary supply. If no sar-up delay is required he poeniomeer is urned fully anic-clockwise (=0). In underfrequency mode ( <f ) he sar up delay can be exended/resared a any ime wih a conrol conac beween erminals X3-M. As long as X3-M is bridged he sar up delay is coninuously on and he frequency is no measured. When he link on X3-M is opened he sar up delay ime resars. In overfrequency mode ( >f ) wih a bridge on X3-M, he lowes poeniomeer ses he measuring signal monioring ime ( S ) (The adjused ime values A / S are idenically). When signal monioring in mode >f is seleced by bridging X3-M he measuring inpu is moniored as follows: If during he adjused monioring ime inerval no measuring signal is deeced, measuring signal alarm is indicaed. As soon as he measuring signal reurns he alarm saus is rese (auo rese seleced) and he monioring inerval S sars again. The alarm saus is indicaed on relay 2 (conacs ) and LED R2 and can be easily differeniaed from under/over frequency alarm where 383

375 Noes boh relays (conacs and ) and LEDs R1 and R2 ) are acive. The deecion of missing measuring signal can increase he safey in criical applicaions on overfrequency. I deecs if he measuring signal is conneced o he inpu of he device and works correcly: I can be checked if he frequency inpu sill delivers pulses. If a Namur sensor is used wih varian /010 higher safey can be achieved by he inegraed shor circui and broken wire deecion. Second speed level / deecion of overspeed and sandsill The signal monioring ime seing in he overfrequency mode can also be used as second speed level, e.g. o deec sandsill in addiion o overspeed. To achieve his, he monioring ime is adjused on he lower poeniomeer o he reverse value of he pulse frequency ha indicaes sandsill. Programming erminals (M-X1-X2-X3): Aenion! The erminals M-X1-X2-X3 have no galvanic separaion o he measuring circui (+U / P / E / 0V) e.g. auxiliary volage DC 24 V M: Common connecion (Ground) of he programming erminals (idenically wih 0V) X1: A response delay of s afer connecion of auxiliary supply is achieved by connecing a X1 o M wih a poeniomeer or fixed resisor (0.25 W) see echnical daa. The delay can be sopped by bridging X1 o M a any ime. If no sar up delay is required he erminals X1-M mus be linked. X2: Manual rese wih NO conac push buon on X2-M, auo rese wih erminals X2-M bridged. X3: When X3-M is bridged in mode underfrequency he sar up delay is coninuously acive or he ime is resared. In mode overfrequency he monioring of he measuring signal is swiched on by bridging X3-M. Adjusmen aid for sar up delay and alarm delay During he elapse of sar up delay and alarm delay he yellow LED R1 and R2 is flashing wih a frequency of 2 Hz. To se a specific ime value in seconds he number of flash pulses can be used o check he seing: Number of flash pulses divided by 2 = ime delay in seconds.

This signal is eiher V or ma or ma. As he X3 erminal is no available, hese varians do no offer indicaion of missing speed signal in overfrequency mode and he sar up delay can only be iniiaed when he auxiliary supply is swiched on.

In his configuraion, all ha is required besides he reference probe "COM" is he "MAX", which mus be locaed a he desired limi level. The oupu relay swiches over afer he se delay ime if he fluid level exceeds or falls below he limi level, which permis fluid o be pumped ou or added. Wihou bridge X1 - COM only relay "MAX" (conacs ) swich, wih bridge X1 - COM boh relays swich ogeher. If for each oupu relay a separae ime delay is necessary, he uni has o be se o separae conrol of he oupus and he "MIN" and "MAX" inpus are conneced o he same probe. Please noe ha he resisance of he liquid is divided up on boh inpu circuis. Therefore he response value mus be seed o he double value. If separae oupu conrol is seleced wih 1-poin conrol for each oupu relay he ime delay can be seed separaely. Because of he seable ime delay of 0.2 o 20 sec for each probe circui, i is possible o suppress early swiching caused by waves on he liquid. Also ime depending level conrol can be realised. The delay works inegraing and is acive when he liquid goes over as well as under he probe level. The wide seing range allows easily an opimum seing so ha he uni can differeniae beween foam and liquid. The response value mus be se o a value high enough, ha he uni reacs when he liquid, bu no when he foam reaches he probe (for seing procedure he ime delay is se o min. value).

For each level he ime delay can be se separaely (v MIN and v MAX ). When he relays are conrolled ogeher, hese work like a relay wih 2 changeover conacs as follows: If he liquid rises above he "MAX" level he oupu relays swich over afer he delay ime of v MAX and sar e.g. a pump o sink he liquid. If he level goes under he "MAX" level he oupu relays remain acivaed unil he "MIN" level is reached. Now he oupu relays swich back afer he ime delay of v MIN and sop he pump.

I is no mandaory o connec he PE o he corresponding device erminals bu i increases he filer effec. The maximum curren in each filer pah is 50 ma. So his filer can also be used in he auxiliary supply of low consumpion equipmen. If only one line should be filered, he 3 pahs could be conneced in series increasing he filer effec, or in parallel increasing he curren capaciy o 150 ma. Funcion Increased numbers of inverers creae on heir oupus seep commuaion edges ha creae noise and high frequency leaking currens on direc conneced equipmen. Devices ha are conneced o inverers can be disurbed or damaged. The HF componens can be conduced o oher pars of he sysem e.g. via he DC 24 V supply. This could happen on measuring relays ha are conneced o he inverer oupu. The auxiliary supply of he measuring relay has a galvanic separaion from he measuring inpu, bu coupling capaciances in he power supply can creae a high frequency connecion o he measuring inpu. Cerain frequencies will hen creae leakage currens from inverer o auxiliary supply. In principle all monioring devices conneced o inverer oupus may be subjec o inerference.
