When he digial inpu opens, he dripping ime se for parameer dd mus hen elapse. Noe: if following he sar of he defros, he digial inpu does no open before he ime dp elapses, he defros will erminae by ime and alarm Ed will be displayed (defros ended by imeou). opening of he digial inpu does no sar he defros only if he defros probe (e.g. B2) emperaure is greaer han d (end defros emperaure on main evaporaor). if a separae defros is configured on wo evaporaors (d3=) and sar/sop defros from exernal conac is se, boh evaporaors are defrosed a he same ime. 7 = Serious alarm Applicaion: exernal alarm ha causes he immediae deacivaion of he oupus on UlraCella (excep hose configured as a ligh/alarm) so as o preven a dangerous siuaion. This can be used, for example, o sop he compressor following acivaion of he Cold room occupied alarm or o deacivae he heaers if an exernal proecion device is acivaed. When he alarm is acivaed: a signal is shown on he display ( SA ); he buzzer is acivaed, if enabled he alarm relay is acivaed, if seleced; 36 The following acions occur on he acuaors: immediae deacivaion of all he oupus (relays), excep for hose configured as lighs and/or alarms. Noe: when shuing down he compressor, he minimum compressor on ime (c3) and he running ime relaing o parameer A6 (sop compressor from exernal alarm) are ignored. if more han one digial inpu is configured as a serious alarm, he alarm is generaed when jus one of he inpus is open Type of defros UlraCella allows you o manage he following ypes of defros, depending on parameer d0: 0. elecric heaer defros by emperaure;. ho gas defros by emperaure; 2. elecric heaer defros by ime; 3 ho gas defros by ime.

UlraCella sofware release.7 feaures new EVDice driver managemen funcions: Possibiliy o configure he EVDice parameers on he UlraCella user inerface (buil-in LED display or UlraCella Service erminal) and/or on he local EVDice LED display user inerface. EVDice cusom configuraion proecion by signaure: as soon as communicaion is esablished, UlraCella signs EVDice by wriing a random number beween and o a regiser on he driver. This allows unique idenificaion of: - EVDice drivers ha have been previously configured - new EVDice drivers (e.g. replaced due o a faul) There are hree possible cases: New insallaion / New sysem / EVDice insalled following insallaion: in his case, he signaure on UlraCella will iniially be 0 -> he acive parameers will be hose se on EVDice, and UlraCella will generae a new signaure. Proceed as follows:. Confirm ha he EVDice is presen by seing IPE= (communicaion wih EVDice enabled), or by answering yes o a specific quesion in he wizard on he UlraCella Service erminal; UlraCella will sign he EVDice so as o creae he conroller-driver combinaion; 2. The IEC (EVDice configuraion error) alarm will be acivaed and he conroller (and he compressor) will sop (UlraCella forces parameer ICG=0, EVDice no enabled for conrol). Configure he EVDice parameers based on he applicaion, eiher using he wizard, or parameer-by-parameer on he LED display inerface; 3. Once all of he required EVDice parameers have been configured, se ICG= o acivae conrol. Seing ICG= also reses he IEC alarm. Replacing EVDice due o a faul / oher causes:. UlraCella will have a signaure oher han 0 (as i has been previously configured o manage an EVDice driver), while he EVDice will have a differen signaure from he one saved on UlraCella (eiher 0 if new, or a number oher han 0 if originaing from anoher insallaion). In his case, he iniially acive parameers will be hose se on UlraCella (he parameers on UlraCella corresponding o he EVDice driver will be copied o he EVDice). Proceed as follows: The IEM alarm (EVDice error mismach) is acive o warn he user ha an elemen in he sysem has been changed. If necessary, modify he EVDice parameers based on he applicaion, eiher using he wizard, or parameer-by-parameer on he LED display inerface; The conroller is will acive even when he IEM alarm is acive; o disable he alarm, press on he UlraCella LED display. 2. The signaure on UlraCella will be equal o 0 (as i is new or has no been previously configured o communicae wih an EVDice driver), while EVDice will have a signaure (signaure oher han 0). In his case, he iniially acive parameers will be hose se on EVDice (he parameers corresponding o he EVDice driver will be copied o UlraCella). The case is idenical o a new insallaion / new sysem: Confirm ha he EVDice is presen by seing IPE= (communicaion wih EVDice enabled), or by answering yes o a specific quesion in he wizard on he UlraCella Service erminal; UlraCella will sign he EVDice so as o creae he conroller-driver combinaion; The IEC (EVDice configuraion error) alarm will be acivaed and he conroller (and he compressor) will sop (UlraCella forces parameer ICG=0, EVDice no enabled for conrol). Configure he EVDice parameers based on he applicaion, eiher using he wizard, or parameer-byparameer on he LED display inerface; Once all of he required EVDice parameers have been configured, se ICG= o acivae conrol. Seing ICG= also reses he IEC alarm. Replacing UlraCella due o a faul / oher causes: The signaure on UlraCella will be equal o 0 (as i is new or has no been previously configured o communicae wih an EVDice driver), while EVDice will have a signaure (signaure oher han 0). In his case, he iniially acive parameers will be hose se on EVDice (he parameers corresponding o he EVDice driver will be copied o UlraCella). The case is idenical o a new insallaion / new sysem. IPE Enable EVDice communicaion 0 0-0/ = disabled / enabled ICG Enable EVDice conrol 0/ = disabled / enabled Noe: when IPE=0 (communicaion wih EVDice disabled), he only parameers visible on he UlraCella buil-in LED display are: IPE, IrE (EVDice operaing mode), IP3 (superhea se poin), PH (ype of refrigeran) and In (EVDice serial address from UlraCella) Noe: he signaure on EVDice can be se o zero using he rese procedure on he buil-in LED inerface (see EVDice manual EN) Noe: he above are valid for EVDice firmware release.4; UlraCella sofware release.7 in any case mainains compaibiliy wih EVDice drivers feauring previous firmware releases. In paricular, he IEC and IEM alarms will be always disabled, parameers IPE and ICG will have always he same value and UlraCella will no generae any signaure Noe: in UlraCella sofware release.7, he EVDice firmware release is read-only when parameer IPE= (communicaion wih EVDice enabled) EVD ICE parameer able The following parameers correspond o he EVD ICE driver, and are configured on UlraCella. 40

In he ho gas defros, he delay d3 is useful for ensuring a sufficien amoun of ho gas before acivaion of he ho gas valve; d4 deermines wheher o acivae or no he defros a he conroller sar-up. The defros a sar-up reques has prioriy over he acivaion of he compressor and he coninuous cycle. Force a defros a conroller sar-up may be useful in special siuaions. Example: frequen power drops inside he plan. In case of lack of volage he ool reses he inner clock ha calculaes he period of ime beween wo defross, saring from zero. If, in an exreme case, he frequency of he power failure were greaer han he defros frequency (e.g. a power failure every 8 hours, agains a defros every 0 hours) he conroller would never perform a defros. In a siuaion of his ype, i is preferable o acivae defros on sar-up, above all if he defros is conrolled by emperaure (probe on he evaporaor), herefore avoiding unnecessary defross or a leas reducing he running imes.
