I feaures 7 analogue inpus for probes and 5 digial inpus, configurable by parameer. The following probes can be used: sauraed evaporaion pressure and superheaed gas emperaure probe, required for superhea conrol, oule, inake and defros probe for showcase emperaure conrol, defros probe for he second evaporaor, wo auxiliary monioring probes, ambien emperaure probe, glass emperaure sensor and humidiy probe o preven he showcase windows from mising. In he laer case he PWM oupus can be used eiher o conrol he glass heaers or he evaporaor fans for air circulaion. If he sepper expansion valve is no used, a second defros probe can be insalled o manage he defros on a second evaporaor. The 5 digial oupus (relays) can conrol he compressor/ solenoid valve, evaporaor fans, defros, ligh and alarm. The digial inpus can be used for swiching beween day and nigh, including from ligh sensor, for he defros calls, for he door or curain swich or o acivae alarms. By creaing a Maser/Slave nework, a series of funcions can be coordinaed, such as defross, nework solenoid valve managemen, sharing of he pressure probe, and sharing of conrol saus.

Analogue inpus S4, S5, S6, S7 can also be configured as digial inpus, called DI1, DI2, DI3, DI4, by seing parameers A4, A5, A10, A11. Inpu DI5 can only be used as a digial inpu, and is configured by parameer A12. See he descripion of he erminals in paragraph 2.2. The probes (emperaure NTC, PTC, PT1000, NTCL243, 0 o 5 Vdc raiomeric and acive probes) can be conneced o he analogue inpus, and have been divided ino 5 groups, wih he same ype of probe for each group. See he able of parameers. Types of probes ha can be conneced o each group Group 1 Group 2 Group 3 Group 4 Group 5 Composiion S1, S2, S3 S4, S5 S6 S7 S8,S9, S10,S11 Parameer for ype of probe /P1 /P2 /P3 /P4 /P5 0 = NTC Sandard - Range 50T90 C 1 = PTC Sandard - Range 50T150 C 2 = PT1000 Sandard - Range 50T150 C 3 = NTC L243 Sandard - Range 50T90 C 4 = 0 o 5V raiomeric probe 5 = 0 o 10 V inpu = 4 o 20 ma inpu Serial probes Tab. 5.a Inpus S6, S7 can be conneced o 0 o 5 V raiomeric pressure probes, remembering however ha can only supply one raiomeric probe. Inpu S7 can noneheless also be conneced o acive probes wih a 4 o 20 ma or 0 o 10 V oupu, which canno be powered direcly by. All hese probes require he range of measuremen o be defined, se by parameers /L6, /U6, /L7, /U7. See he able of parameers. Probe 6 Probe 7 Minimum value Maximum value Minimum value Maximum value /L6 /U6 /L7 /U7 Tab. 5.b can adjus he values read by he probes. In paricular, /c1 o c7 are used o increase or decrease he physical values read by he probes, if configured as emperaure probes. Parameer /ce, on he oher hand, correcs he value of he sauraed evaporaion emperaure calculaed direcly based on he evaporaion pressure. The serial probes canno be calibraed, while he probes shared wih he Maser (such as he pressure probe) are calibraed by he Maser. To assign he funcions o each physical or serial probe, se parameers /FA,/Fb, /Fn. See he able of parameers.

This mus be conneced o he Maser. On he Maser, simply correcly configure he using he parameers /FE, /U6, /L6, while on he Slaves, se /FE=0 (funcion disabled). In his way, he Slaves auomaically search for he pressure value shared by he Maser and used for calculaing he local superhea. This is used o save on he insallaion coss of a pressure probe for each evaporaor, assuming ha he pressure drop in ha secion of he line is negligible. Probe posiioning and purchase codes The following probes are recommended by CAREL: evaporaor oule emperaure probe: NTC***HF01; evaporaion pressure probe: SPKT0013R0: raiomeric -1 o 9.3 bars; SPKT0053R0: raiomeric -1 o 4.2 bars; SPKT0033R0: raiomeric -1 o 34.5 bars.

The emperaure and humidiy probes mus no be posiioned oo far from he showcases hey are measuring. A imes i is beer o insall more han one if he supermarke is divided ino secions wih grealy differing emperaure and humidiy values (frozen secion, mea secion, frui and vegeable secion, ec.) glass emperaure probe: NTC060WG00. The glass emperaure probe is conneced a he coldes poin of he glass on he showcase, so as o opimise operaion of he ani-swea device (heaers or fans). See insrucion shee ligh sensor: PSOPZLHT00. This mus be insalled where i can see he lighs in he supermarke, and no he showcase, so as o auomae day/nigh changeover.

The defaul configuraion for he assignmen of he conrol probes is as follows: S1 = Oule probe (Sm); S2 = Defros probe (Sd); S3 = Inake probe (Sr). The defaul configuraion also involves hese hree probes being sandard CAREL NTC. However, oher ypes of probes can be conneced by seing parameer /P1, if he produc code allows ha. On he defaul seings can be changed o choose he funcion associaed wih any of he probes conneced. There are also cases where he characerisics of he applicaions require differen seings. Examples: Conrol inside a cold room is normally performed using jus wo emperaure probes, in paricular he inake emperaure is no read. In his case, he possible configuraion may be: /FA=1: oule emperaure on probe S1 (Sm=S1); /Fb=2: defros emperaure on probe S2 (Sd=S2); /Fc=0: no inake emperaure; Alernaively: /FA=1: oule emperaure on probe S1 (Sm=S1); /Fb=3: defros emperaure on probe S3 (Sd=S3); /Fc=0: no inake emperaure. Noe: acivaion of he coninuous cycle on he Maser means all he dependen Slave observe he compressor managemen imes of he Maser conroller (only parameer cc on he Maser has an effec, while he values se on he Slaves are ignored). This operaing mode is only highlighed on he Maser user erminal, as he Slave conrollers ignore he Maser conrol mode. This means ha a Slave conroller serving he Maser, even in he coninuous cycle, manages he user inerface as if i were in normal conrol (compressor icon on during cooling reques and off when no reques). Aemps o acivae coninuous cycle on a Slave serving he Maser are ignored, boh local and sen from he Maser. Noe: if he Maser conroller eners duy seing mode, he relaed Slave conrollers follow as regards he compressor managemen imes and he user inerface does no show he icon flashing when he compressor is off, due o he fac ha hey ignore he Maser conrol mode. On he oher hand, if he Slaves ener duy seing mode due o lack of communicaion wih he Maser; in his case hey manage he user inerface correcly. Calibraion (parameers /c1, /c2, /c3) can adjus he values read by he probes and some of he inernal variables. In paricular, /c1 o /c3 are used o increase or decrease he values read by he physical probes conneced o he inpus S1, S2, S3, if configured as emperaure probes. Parameer /ce, on he oher hand, correcs he value of he sauraed evaporaion emperaure calculaed direcly based on he evaporaion pressure. The serial probes canno be calibraed, while he probes shared wih he Maser are calibraed by he Maser. T2 Share conrol saus This funcion is used o saisfy he needs of cold rooms or showcases wih muliple evaporaors, where he Slaves are essenially used as expansions for he managemen of differen elecronic valves. This funcion shares he Maser conrol saus across he LAN nework. In his way, he Maser deermines he conrol saus, and each Slave operaes as a consequence, wihou consider he parameers se locally. This means Slave conrollers can be used wihou oule and inake probes. If he Slave conroller is no accessible from he Maser, duy seing operaing mode mus be acivaed, seing he corresponding parameer c4 >0. Acivaion: o acivae sharing of he conrol saus, se /FA = 0 and /Fc = 0 on he conrollers Slave. Noe: Key T1 T2 A min, max A min Fig. 5.b Temperaure read by he probe Value calibraed by T1 Offse Range of measuremen max T1 he configuraion /FA = 0 and /Fc = 0 on a Maser conroller causes he alarm re ; if he Slave conroller is no accessible from he Maser, alarm MA is displayed. The funcion manages he conrol saus (acivaion and deacivaion of he cooling reques) on he Slave conrollers from he Maser via he LAN nework. This means ha only he Maser parameers (se poin, differenial, nigh-ime se poin variaion, conrol offse in he even of probe error) affec he conrol algorihm. The value of he Slave parameers has absoluely no influence. If he Slave conroller is no accessible from he Maser (he user inerface shows alarm MA ), duy seing mode is acivaed based on he local seing of parameer c4, and he corresponding managemen (duy seing sars in he saus found prior o he insan i is acivaed, i.e. i sars wih compressor on if his was on, and wih compressor off if i was off ).

32 5.2 Digial inpus Inroducion manages up o 5 physical digial inpus and one virual digial inpu. Of hese, as already menioned, DI1, DI2, DI3, DI4 are analogue/ digial inpus, configured as digial inpus by heir respecive parameers A4, A5, A10, A11, while DI5 is only a digial inpu and can be configured using parameer A12. See he general connecion diagram in paragraph 2.8. The virual digial inpu is a funcion whereby he saus of a digial inpu is propagaed via LAN from Maser o Slave. This is useful, for example, for a curain swich, allowing swiching from day o nigh saus and viceversa wihou having o connec addiional wiring from he Maser o he Slaves. The virual digial inpu can be configured from he supervisor or he Maser, based on he seing of parameer A9 (only seable on he Maser). A physical inpu on he Maser can be associaed wih he virual digial inpu on he Maser, o be propagaed o he Slaves. This is some using a parameer, eiher A4, A5, A10, A11 or A12 (based on he seing of A9) se on he Maser, and parameer A8 se on he Slave. See he advanced parameers explained in paragraph 6.2. Noe: if needed, parameer A8 can have differen seings on he Slaves, so as o acivae differen funcions. The able below liss he various funcions ha can be acivaed by digial inpu, when closing or opening he corresponding conac. Digial inpus S4/DI1 S5/DI2 S6/DI3 S7/DI4 DI5 Parameer A4 A5 A10 A11 A12 Funcions of he digial inpus (Parameers A4, A5, A10, A11, A12) Selecion Conac open closed 0 = inpu no acive = immediae exernal alarm acive no acive 2 = delayed exernal alarm acive no acive 3 = enable defros no enabled enabled 4 = defros call no acive acive 5 = door swich door open door closed 6 = remoe / 7 = curain swich/ligh day saus nigh saus 8 = sar/sop coninuous cycle no acive acive 9 = ligh sensor - - Tab. 5.f 1 = Immediae exernal alarm Acivaion of he alarm causes: message IA shown on he display and alarm icon (riangle) flashing; acivaion of he buzzer (o configure his funcion, see parameer H4); acivaion of he alarm relay (if configured, see parameers H1, H5, H7); deacivaion of he compressor/solenoid oupu (o configure his funcion, see parameer A6). Noe: acivaion of he exernal alarm shus down he evaporaor fans only if hese follow he saus of he compressor oupu, as se for parameer F2. When he compressor is shu down due o an exernal alarm he compressor ime is ignored (parameer c3). 2 = Delayed exernal alarm The operaion of his alarm depends on he seing of parameer A7 (delay ime for delayed exernal alarm): A7=0: signal only alarm on he display, normal operaion of he conroller is no affeced (defaul); A7 0: alarm similar o he immediae exernal alarm, acivaion is delayed by he ime se for A7. 3 = Enable defros Used o disable any defros calls. When he conac is open, all defros calls are ignored. Parameer d5 can be used o delay acivaion. Noe: if he conac is open while a defros is in progress, his is immediaely sopped, he defros icon flashes on he display indicaing he defros call is acive (his sars again when he conac closes); his funcion may be useful o preven defross on conrollers exposed o he public during sore opening hours, and o be able o perform special ho gas defross. 4 = Defros call The closing of he digial conac sars he defros, if enabled. In he even of Maser Slave nework connecion, if he conroller is he Maser, he defros will be a nework defros, while if i is a Slave, i will only be a local defros. The defros digial inpu can be used effecively o perform real ime defross. Simply connec a imer o he mulifuncion digial inpu on he Maser and use d5 o delay he defross on he various Slaves and hus avoid curren overloads. Noe: if he defros is inhibied by anoher digial inpu configured as enable defros, he defros calls are ignored. 5 = Door swich Door open: sop conrol (shudown compressor/solenoid and evaporaor fans); swich ligh on (if configured, see parameers H1, H5, H7); alarm icon (riangle) flashing on he display; disable emperaure alarm. Door closed: resume conrol; swich ligh off (if configured, see parameers H1, H5, H7); riangle icon sops flashing on he display; enable emperaure alarm afer bypass ime defined by parameer d8.
