In such cases forced coolng of the unt must be consdered (e.g. by usng a ventlator). The unt s desgned for operaton n an ndustral envronment and must not be used n a household envronment or smlar. 2. GENERAL CHARACTERISTICS The TVU Seres meter s equpped wth one current nput (0-20mA), two voltage nputs (0-10V and mv), one RTD nput (Pt 100/500/1000) and one TC nput (thermocouple: K, S, J, T, N, R, B, E). Temperature of cold ends s compensated automatcally. RTD and TC nputs are fully lnearsed. It s allowed to use only one nput at the same tme. Input ranges are descrbed n the next chapter. Result s showed on 4-dgt LED dsplay. The devce can be equpped wth two or four relay (or OC type) outputs. Optonally TVU Seres can be equpped wth actve current output, passve solated current output or actve voltage output. Devce TVU Seres s equpped wth RS-485 / Modbus RTU communcaton nterface and sensor supply output. The meter can be ordered n two power supply versons. The devce has 4 buttons beng used for man presets programmng. To get hgh protecton level, the keyboard s mounted under transparent cover. To allow user to change presets wthout openng the cover, an IR sensor s mounted. Remote controller keyboard s equvalent to the devce keyboard (Note, that remote controller s not a part of the TVU Seres set t s an addtonal equpment). TVU Seres can be used for controllng and regulaton of processes need proportonal and threshold control lke: temperature processes (heatng or coolng), valves controllng or other. 4

In order to take full advantage of these characterstcs nstallaton of the unt must be conducted correctly and accordng to the local regulatons.! - Read the basc safety requrements on page 3 pror to startng the nstallaton. - Ensure that the power supply network voltage corresponds to the nomnal voltage stated on the unt s dentfcaton label. - The load must correspond to the requrements lsted n the techncal data. - All nstallaton works must be conducted wth a dsconnected power supply. - Protectng the power supply connectons aganst unauthorzed persons must be taken nto consderaton UNPACKING After removng the unt from the protectve packagng, check for transportaton damage. Any transportaton damage must be mmedately reported to the carrer. Also, wrte down the unt seral number located on the housng and report the damage to the manufacturer. Attached wth the unt please fnd: - user s manual, - warranty, 4.2. ASSEMBLY! - Dsconnect the power supply pror to startng assembly. - Check the connectons are wred correctly pror to swtchng the unt on.! To nstall devce on the wall, a pnholes should be made. Fgure 4.1 presents dmensons of the devce and dstances between holes. The back sde of the devce has four mountng holes. Ths part of the case should be mounted to a wall by screws. 8

10 4.3. CONNECTION METHOD Cauton! - Installaton should be conducted by qualfed personnel. Durng nstallaton all avalable safety requrements should be consdered. The ftter s responsble for executng the nstallaton accordng to ths manual, local safety and EMC regulatons. - The unt s not equpped wth an nternal fuse or power supply crcut breaker. Because of ths an external tme-delay cut-out fuse wth a small nomnal current value must be used (recommended bpolar, max. 2A) and a power supply crcutbreaker located near the unt. In the case of usng a monopolar fuse t must be mounted on the phase cable (L). - The power supply network cable dameter must be selected n such a way that n the case of a short crcut of the cable from the sde of the unt the cable shall be protected aganst destructon wth an electrcal nstallaton fuse. - Wrng must meet approprate standards and local regulatons and laws. - In order to secure aganst accdental short crcut the connecton cables must be termnated wth approprate nsulated cable tps. - Tghten the clampng screws. The recommended tghtenng torque s 0.5 Nm. Loose screws can cause fre or defectve operaton. Over tghtenng can lead to damagng the connectons nsde the unts and breakng the thread. - In the case of the unt beng ftted wth separable clamps they should be nserted nto approprate connectors n the unt, even f they are not used for any connectons. - Unused termnals (marked as n.c.) must not be used for connectng any connectng cables (e.g. as brdges), because ths can cause damage to the equpment or electrc shock. - If the unt s equpped wth housng, covers and sealng to, protectng aganst water ntruson, pay specal attenton to ther correct tghtenng or clampng. In the case of any doubt consder usng addtonal preventve measures (covers, roofng, seals, etc.). Carelessly executed assembly can ncrease the rsk of electrc shock. - After the nstallaton s completed do not touch the unt s connectons when t s swtched on, because t carres the rsk of electrcal shock. Due to possble sgnfcant nterference n ndustral nstallatons approprate measures assurng correct operaton of the unt must be appled. To avod the unt of mproper ndcatons keep recommendatons lsted below. Avod runnng sgnal cables and transmsson cables together wth power supply cables and cables controllng nductve loads (e.g. contactors). Such cables should cross at a rght angle. Contactor cols and nductve loads should be equpped wth nterference protecton systems, e.g. RC-type. 10

11 Use of screened sgnal cables s recommended. Sgnal cable screens should be connected to the earthng only at one of the ends of the screened cable. In the case of magnetcally nduced nterference the use of twsted par of sgnal cables s recommended. Twsted par (best f shelded) must be used wth RS-485 seral transmsson connectons. In the case of measurement or control sgnals are longer than 30m or go outsde of the buldng then addtonal safety crcuts are requred. In the case of nterference from the power supply sde the use of approprate nterference flters s recommended. Bear n mnd that the connecton between the flter and the unt should be as short as possble and the metal housng of the flter must be connected to the earth wth the largest possble surface. The cables connected to the flter output must not be run wth cables wth nterference (e.g. crcuts controllng relays or contactors). Connectons of power supply voltage and measurement sgnals are executed usng the screw connectons on the back of the unt s housng. max. 2 mm 6-7 mm! Fgure 4.2.

19 4.4. MAINTENANCE The unt does not have any nternal replaceable or adjustable components avalable to the user. Pay attenton to the ambent temperature n the room where the unt s operatng. Excessvely hgh temperatures cause faster ageng of the nternal components and shorten the fault-free tme of the unt's operaton. In cases where the unt gets drty do not clean wth solvents. For cleanng use warm water wth small amount of detergent or n the case of more sgnfcant contamnaton ethyl or sopropyl alcohol.! Usng any other agents can cause permanent damage to the housng. Product marked wth ths symbol should not be placed n muncpal waste. Please check local regulatons for dsposal of electronc products. 5.

PRINCIPLE OF OPERATION After turnng the power supply on, devce ID and software verson are showed on the dsplay, next the controller goes to the measurement mode MEASUREMENT MODE In the measure mode, the measurement results, converted over selected characterstc, are dsplayed on the LED dsplay. The measurement range equal to the nomnal range s called: nomnal measurement range, and the measurement range equal to the extended nomnal range s called: permssble measurement range (Fgure 6.1, 6.2). For temperature nputs (TC and RTD) there s lnear characterstc avalable only. For ths knd of nputs nomnal measurement range, and permssble measurement range are the same (no range extenson avalable, Fgure 6.3).

Defntons of measurement ranges n mode 4 20mA If the result of measurement exceeds the permssble measurement range, warnng -H- or -Lo- s dsplayed rather than nput sgnal, dependng on exceeded value (see descrpton of Lo r and H r parameters, paragraph npt menu). The warnng can be effect of measurement crcut malfuncton. In that case -Lo- means shortcut and -H- means break of measurement crcut. If sensor falure wll be detected (e.g. broken wres), then S.Err warnng wll be dsplayed. nomnal measurement range H r parameter 0 mv 150 mv permssble measurement range Fgure 6.2.

Defntons of measurement ranges n mode Pt100 In the measurement mode user can check man thresholds values. After pressng [^] or [v] button, name of the threshold (e.g. rel1 ) and hs value wll be dsplayed on the dsplay n alternatng mode. If [^] or [v] wll be pressed n 5 sec agan, the next threshold wll be dsplayed, else the devce comes back to the measurement mode. If a free access s enabled (see descrpton of SECu menu), user can change the value of partcular threshold pressng button [] (see: PARAMETERS EDITION). All accessble parameters can be changed by enterng the menu (see: DEVICE PROGRAMMING). Use the local keyboard or the remote controller to do t. (Note: all parameters can be remote changed va RS-485 nterface). Confguraton of the devce (va menu or RS-485 nterface) does not stop measures DETECTION OF THE PEAK VALUES The TVU Seres controller s equpped wth peaks detecton functon. It can detect a peaks of the nput sgnal and dsplay ther values. Presets connected wth ths functon are placed n HOLd menu (see descrpton of HOLd menu). The detecton of the peak can be done f the measured sgnal rases and drops of value at least equal to parameter PEA. Detected peaks are dsplayed durng the tme defned by parameter tme. If a new peak wll be detected whle one s dsplayed, ths new peak wll be dsplayed and dsplay tme counter wll be cleared (Fgure 6.4). If no peaks are detected whle tme tme elapses, devce starts to show the current value of nput sgnal agan. If HdS = HOLD then settng parameter "tme"=0.0 causes holdng peak value untl [] button s pressed. If HdS = real then value "tme"=0.0 means no holdng. Dsplayng peak value s sgnalzed by flashng most rght decmal pont. The relays/leds and analogue outputs can be controlled depend on the current value of nput sgnal or the peak value (see HOLd menu). 21

CONTROL OF THE RELAY OUTPUTS The control of the object (measured sgnal) s realzed va relay outputs. Front panel LEDs named R ndcates the state of partcular relay output. If devce s not equpped wth one or more relay outputs, menus refer to ths relays are avalable, but apply to LED ndcators only. In such case LEDs ndcates exceedng of partcular thresholds. Modes of the control can be changed depend on the values of parameters SEtP, SEt2, HYSt, mode, t on, toff, unt and AL. Depend on mode parameter, relays can be not used or controlled over one or two thresholds values. If one threshold s used (Fgure 6.5) the relay can be turned on ( mode = on ) or off ( mode = off ) when the nput sgnal value s contaned n zone A. If two thresholds are used (Fgure 6.6) the relay wll be turned on when value of nput sgnal s contaned n zone A ( mode = n ) or zone B ( mode = out ) and turned off f the sgnal s contaned n the second one. state of relay/led SEtP parameter zone B zone A measure HYSt parameter 22 Fgure 6.5.

The relay can change hs state only when nput value exceeds (over or under) border value and ta,tb,tc,td tmes (Fgure 6.7) are bgger than the tme defned by parameters t on, toff and unt. Border values means values equal threshold+hysteress and threshold-hysteress respectvely. If t on and toff parameters are set to 0, then the relay state wll be changed as soon as nput value exceeds any of the border values (see ponts A and C, Fgure 6.7 a, b, c). If values of t on or/and toff are postve, then relay state wll be turned on f the nput value exceeds the border values and stay bgger (or lower) durng at least t on (see ponts B ON, D ON, Fgure 6.7 a, d, e). Smlarly, the relay wll be turned off f tme toff elapse snce the nput sgnal value exceeds any of the border values (see ponts B OFF, D OFF, Fgure 6.7 a, d, e). If ta,tb,tc or td (when nput sgnal stay n zone A or zone B) are lower than parameters t on or toff, the relay wll not change hs state (see ponts A and C, Fgure 6.7 a, d, e). The state of relay output whle the nput value exceeds the border values (ponts A, B, C, D) s descrbed by parameter mode. The relay can be turned on ( mode = on ), or turned off ( mode = off ) when nput sgnal value s contaned n zone A (Fgure 6.7 a). The parameter AL allow user to set the relay output behavour n crtcal stuatons (e. g. nput values exceeds permssble measurement range). User can select that the relays wll be turned on, turned off,or not changed n crtcal stuatons. All parameters connected wth relay outputs are descrbed n paragraph rel1 menu. 24

Prncple of LED/relay output operaton for two thresholds mode Fgure 6.8 presents the prncple of relay outputs operaton for two thresholds mode, and an example values of other parameters. In ths mode parameter SEt2 s accessble n common wth SEtP, ths parameter descrbes a second threshold of the relay output. The parameters HYSt, mode, t on, toff, unt and AL are connected wth both SEtP and SEt2 thresholds. Whle the controllng process, the relay output changes hs state depends of both SEtP and SEt2 thresholds n smlar way as t was descrbed n one threshold mode. If two threshold mode s used, mode parameter defnes state of the relay output when the nput value occurs n a partcular zone defned by border values of both thresholds. The relay can be turned on f the nput value s contaned n zone A ( mode = n ) or zone B ( mode = out ) and turned off f t s contaned n the second one (Fgure 6.8). open closed open toff parameter t on parameter closed t on parameter tme tme tme tme tme 25

26 The sequence of thresholds SEtP and SEt2 can be set n any order, due to the control of relay outputs s done depend on dfference between thresholds values (zone A ) and outsde of threshold values (zone B). 7. DEVICE PROGRAMMING The devce menu allow user to set all parameters connected to operaton of measurement nput, control modes, crtcal stuatons behavour, communcaton va RS-485 and access settngs.

29 rel1 menu Ths menu allows to confgure the operaton mode of relays and LEDs marked R (e.g. R1 ). If there are few relay outputs avalable, then every output has ts own confguraton menu (e.g. menu rel2 for relay (LED) R2 ). Prncple of the relays operaton s descrbed n paragraph CONTROL OF THE RELAY OUTPUTS. SEtP SEt2 HYSt The relay outputs and LEDs (named R) can be controlled depend on both - the current value and the peak value (when peak detecton s actve) of the nput sgnal. If devce s not equpped wth one or more relay outputs, menus refer to ths relays are avalable, but apply to LED ndcators only. In such case LEDs ndcates exceedng of partcular thresholds. - frst threshold of the relay (range ). Negatve values can be nput by selectng a - sgn on frst dgt (to change value use [^] and [v] buttons). Threshold s the medum value of relay hysteress. - second threshold of the relay (range ). Negatve values can be nput by selectng a - sgn on frst dgt ( to change value use [^] and [v] buttons). Ths threshold s accessble when mode parameter s set to n or out value. Threshold s the medum value of relay hysteress. - hysteress of relay (range 0 999). Full hysteress of the relay s equal to 2 tmes HYSt parameter. The relay state can change when an nput sgnal s out of threshold-hysteress to threshold+hysteress zone. Presented parameters should be set to ensure that SEtP + HYSt, SEt2 + HYSt, SEtP - HYSt or SEt2 - HYSt does not exceed the measure range. Addtonally, n two threshold mode ( mode = n or out ), the hysteress for both thresholds must not cover each other (n other case relay can't change hs state). mode - relay operaton mode: noac on off n - the relay s not actve (permanent turned off) - one threshold mode, the relay s turned ON when nput sgnal exceeds SEtP + HYSt value, and s turned off back when the nput sgnal became lower than SEtP HYSt, - one threshold mode, the relay s turned OFF when nput sgnal exceeds SEtP + HYSt value, and s turned on back when the nput sgnal became lower than SEtP HYSt, - two threshold mode, the relay s turned ON when the nput sgnal s bgger than lower threshold + HYSt and lower than bgger threshold HYSt, and turned off when the nput sgnal s contaned n the second zone. The bgger threshold means bgger one of SEtP and SEt2 thresholds, the lower threshold means lower one of SEtP and SEt2 thresholds. 29

30 out - two threshold mode, relay s turned ON when the nput value s bgger than bgger threshold + HYSt and lower than lower threshold HYSt, and turned on when the nput sgnal s contaned n the second zone. The bgger threshold means bgger one of SEtP and SEt2 thresholds, the lower threshold means lower one of SEtP and SEt2 thresholds. modb - the relay s controlled va RS-485 nterface, ndependently on the nput sgnal. LEDs lght when relays are closed, ndependently of relays' mode. When power supply fal, unt do not store relays state selected by RS-485 nterface. t on - turn on delay tme, the relay s turned on wth delay equal t on f the nput value exceeds approprate border value (defned wth threshold and hysteress), at least t on tme. t on range , defned wth 0.1 sec. resoluton. Unt of ths parameter s set by unt parameter. toff unt - turn off delay tme, the relay s turned off wth delay equal toff f the nput value exceeds approprate border value (defned wth threshold and hysteress), at least toff tme. toff range , defned wth 0.1 sec. resoluton. Unt of ths parameter s set by unt parameter. If tme when the nput sgnal exceeds some border value s shorter than t on or toff tme, the relay do not change ts state (see paragraph: CONTROL OF THE RELAY OUTPUTS). - unt of tme for t on and toff parameters. Can be set on one of two values: mn SEC - mnutes, - seconds. AL - ths parameter defnes the relay reacton when some crtcal stuatons occurs: noch on off - relay do not change hs state, - relay wll be turned on, - relay wll be turned off. If parameter mode s set to on, off, n or Out the crtcal stuaton means that allowable measurement range s exceeded. If parameter mode s set to modb, the crtcal stuaton means communcaton delay (when no data s receved) longer than mbto parameter (see descrpton: rs menu). 30

31 If opton noch s selected for AL parameter, behavour of the relay may depend on FLt parameter n some cases. If FLt s set to bg value and the nput sgnal drops, result value of the measure wll change slow, causes of turnng on or off relay due to thresholds values. The crtcal stuaton s slowly detected, so t s mpossble to predct the relay state n that stuatons.

In ths case the converson characterstc s reversed, t means that f nput value rases the output value falls. - ths parameters defne the output value range. If calculated output value Out exceeds defned range then analogue output generates sgnal equal to upper or lower border of the defned range. These parameters defnes the percentage extenson of nomnal analogue range (wth 0,1% resoluton). Parameter Lo r defnes lower border of the range due to formula: Out mn = A - (A Lo r %), where: A lower sgnal value range lmt. Ths parameter can be set from 0 to 99.9% (for actve current output and actve voltage output) or from 0 to 29.9% (for passve current output).

43 8. OVER-CURRENT PROTECTION The current nput of the devce s equpped wth over-current protecton crcut. Ths crcut protects the standard resstor to damage. Maxmum nput current s set to 50mA (typcal). When temperature of the standard resstor falls, the protecton crcut wll turn off hmself automatcally, and the devce wll measure the nput current agan. Due to thermal phenomenon n the standard resstor, precson of the measurement may be lower, durng few mnutes (up to the standard resstor temperature wll falls to the envronment temperature). 9. DISPLAYED VALUES CALCULATION For smplcty of examples t's assumed that current nput s selected, and all calculatons are related to ths nput. When voltage nput s selected calculatons are smlar (be sure of partcular ranges and unts). The frst step to compute the result of measure s the calculaton of the normalzed result (t means result of 0-1 range). To do t, the begn of the nput range (0 ma for 0-20mA range, and 4mA for 4-20mA range) must be subtracted from measured value. Next, receved result must be dvded by the wdth of the nput range ( t means 20mA for 0-20mA range, and 16mA for 4-20mA range). So normalzed result can be expressed by expressons: I n = I np I n = I np. 20 for 4 20mA range for 0 20mA range where I np. Means nput current (n ma), and I n normalzed result. If measured value exceeds the nomnal nput range (0-20mA or 4-20mA), and do not exceed the permssble nput range, then receved normalzed I n result wll exceed 0-1 range, e.g. nput range 4-20 ma, nput current = 3 ma the normalzed result s equal -0,0625, and for nput current = 22 ma, the normalzed result s equal 1,125. In such cases presented expressons are stll correct ADDITIONAL CALCULATIONS (USED CONVERSION CHARACTERISTIC) The manner of the addtonal computaton of the dsplayed result depends on selected converson characterstc. All presented charts are connected wth the nput range 4-20 ma. 43

44 Lnear characterstc The normalzed result s converted by fxed coeffcents determned by Lo C and H C parameters (when the normalzed results s equal 0, then value Lo C s dsplayed, and when the normalzed results s equal 1, then value H C s dsplayed). Expresson presented below shows the manner of result calculaton: where W means the dsplayed value. W =I n "H C" "Lo C" "Lo C", The value of the Lo C parameter can be hgher than the value of H C parameter. In such a case, for an ncreasng value of nput current the dsplayed value decreases. H C Lo C Dsplayed value Dsplayed value Lo C H C Input current [ma] Input current [ma] Fgure. 9.1 Normal ( Lo C < H C) and nverted ( Lo C > H C) characterstc Square characterstc The normalzed result s squared and further converson s done as for lnear characterstc.

45 Square root characterstc The normalzed result s rooted and further converson s done as for lnear characterstc. Converson s made accordngly wth the expresson: where W means the dsplayed value. W = I n "H C" "Lo C" "Lo C", Showed above expresson s not vald when normalzed result s negatve. It s possble for 4-20 mode only. In ths case (I n<0) the dsplayed result s equal Lo C (see graphs below). H C Lo C Dsplayed value Dsplayed value Lo C Input current [ma] H C Input current [ma] Fgure. 9.3 Normal ( Lo C < H C) and nverted ( Lo C > H C) characterstc User defned characterstc User defned characterstc s defned as set of X-Y ponts. Number of the ponts s varable and may be set from 2 to 20 ponts whch make lnear segments (see graph and see Menu npt ). Due to the normalzed result I n, the devce computes specfc segment, e.g. for characterstc from fgure below, and I n = 0,65 the segment between ponts X = and X = wll be chosen. Let's mark those ponts as PL (pont low) and PH (pont hgh) - n ths example PL= 50.0, and PH = 70.0., and the normalzed result I n for the pont PL as I p (n ths example I p = I n(pl) = 0,5). The dsplayed result s calculated accordngly to the expresson: W = I n I p [Y PH Y PL ] 100 Y PL [ X PH X PL ] where Y(PH), X(PH), Y(PL), X(PL) mean values of X and Y coordnates of PH and PL ponts. If the normalzed result exceeds the user defned characterstc values, then specfc utmost segment, defned by two next ponts, s used for calculatons. If characterstc from fgure below s used, and f I n>1 then segment defned by ponts X(PL) = 90.0., X(PH) = wll be used. 45

EXAMPLES OF CALCULATIONS Example 1: Selecton of the permssble nput range ( 4-20 mode) If n 4-20 mode the user sets Lo r = 20,0% and H r = 10,0%, then permssble nput currents range wll be equal: 3,2 ma 22 ma. Lower border of the range s the result of calculatons: 4 ma - 4 ma 20%, and the hgher : 20 ma + 20 ma 10%. Example 2: The normalzed I n result calculaton Let the nput mode = 4-20 ma. The normalzed I n result s calculated accordngly to the expresson on page 43, so f I n = 10 ma then 10 ma - 4 ma = 6 ma, and ths result should be dvded by the wdth of nput range (16 ma). Fnally the normalzed result: I n = 6/16 = 0,375. In case when nput current exceeds nomnal measurement range, calculatons are smlar. For example f nput current s equal 2,5 ma then I n = -0,0938, and f nput current s equal 20,5 ma then I n = 1,0313. Example 3: The lnear characterstc Let the nput mode = 4-20 ma, and parameters Lo C and H C equal to -300 and 1200 respectvely. The calculatons wll be done for three dfferent nput currents from example 2. 46

47 a) I n =10 ma and I n = 0,375 Accordngly to expresson on page 44 for lnear characterstc: 0,375 [1200 -(- 562 and next, the Lo C value s added to the result, so the dsplayed value: (-300) = 262 b) I n = 2,5 ma and I n = -0, c) I n = 20,5 ma and I n = 1, Example 4: The square characterstc Let the nput mode = 4-20 ma, and parameters Lo C and H C equal to -300 and 1200 respectvely. The calculatons wll be done for there dfferent nput currents from example 2. a) I n =10 ma and I n = 0,375 Accordngly to expresson on page 44 for square characterstc: (0,375) 2 [1200 -( and next, the Lo C value s added to the result, so the dsplayed value: (-300) = -89 b) I n = 2,5 ma and I n = -0, c) I n = 20,5 ma and I n = 1, Example 5: The square root characterstc Let the nput mode = 4-20 ma, and parameters Lo C and H C equal to -300 and 1200 respectvely. The calculatons wll be done for there dfferent nput currents from example 2. a) I n =10 ma and I n = 0,375 Accordngly to expresson on page 45 for square root characterstc: 0,375 [1200 -( and next, the Lo C value s added to the result, so the dsplayed value: (-300) = 619 b) I n = 2,5 ma and I n = -0,0938, normalzed result s negatve, so the dsplayed value s equal to Lo C parameter: Lo C = c) I n = 20,5 ma and I n = 1,

48 Example 6: The user defned characterstc Let the nput mode = 4-20 ma, and the user selected the 10 segment characterstc. To do ths t s necessary to enter X and Y coordnates of 11 ponts (see Menu npt ). The calculatons wll be done for three dfferent nput currents from example 2, so n calculatons some of the segments wll be used only. Let the followng ponts wll be gven: X1 = 00.0., Y1 = -50.0, X2= 10.0., Y2 = -30.0,... X6 = 30.0., Y6 = 30.0, X7 = 40.0., Y7 = 80.0,... X10 = 90.0., Y10 = 900.0, X11 = , Y11 = 820.0, Addtonally all other ponts must to be defned and stored n the devce memory. a) I n =10 ma and I n = 0,375 The segment defned by X6 = and X7 = for ths I n wll be selected. Accordngly to expressons gven for user defned characterstc (see page 45) X6(PL) = 30, Y6(PL) = 30, X7(PH) = 40, Y7(PH) = 80 and I p = 0,3, the dsplayed value : W = I n I p [Y PH Y PL ] 100 Y PL = [ X PH X PL ] = 0,375 0,3 [80 30] [ 40 30] b) I n = 2,5 ma and I n = -0,0938, because of the normalzed I n value s lower than 0, the segment defned by X1 and X2 wll be selected. X1(PL) = 0, Y1(PL) = -50, X2(PH) = 10, Y2(PH) = -30 and I p = 0. For these values the dsplayed value -69. c) I n = 20,5 ma and I n = 1,0313., because of the normalzed I n value s hgher than 1, the segment defned by X10 and X11 wll be selected, and X10(PL) = 90, Y10(PL) = 900, X11(PH) = 100, Y11(PH) = 820 and I p = 0,9 for these values the dsplayed value 795. Example 7: Current output value calculaton Lets assume that we have actve current output and ts parameters are: mode = 4-20, OUtL = 100, OUtH = 200, Lo r = 5.0, H r = 5.0 Parameters Lo r and H r defne workng range of current output to ma. Output current wll be calculated for three dsplayed values D : a) D = 17.5 Accordng to formula from page 35: I out = ( ) / ( ) 16 ma + 4 ma = = 16 ma 48

49 Calculated I out do not exceeds the output workng range ( ma). b) D = 20.5 Accordng to formula from page 35: I out = ( ) / ( ) 16 ma + 4 ma = = ma Calculated I out do not exceeds the output workng range ( ma). c) D = 30.0 Accordng to formula from page 35: I out = ( ) / ( ) 16 ma + 4 ma = = 36 ma. Calculated I out exceeds the output workng range (3-21 ma), so current output wll generate current equal to the upper border of range defned by parameter Lo r and H r (t means 21 ma). 10.
