To improve immuniy o disurbance, use probes wih shielded cables (connec only one end of he shield o he earh on he elecrical panel); 2. program he conroller: as shown in he chapers Commissioning and User inerface ; 3. connec he acuaors: he acuaors should only be conneced afer having programmed he conroller. Carefully check he maximum relay capaciies, as indicaed in he echnical specificaions ; 4. serial nework connecion: all conrollers are fied wih a serial connecor for connecion o he supervisor nework via he serial inerface (IROPZ485*0). The secondary of he ransformers ha supply he conrollers mus no be earhed. If connecion o a ransformer wih earhed secondary winding is required, an insulaing ransformer mus be insalled in beween. Warnings: avoid insalling he conroller in environmens wih he following characerisics: relaive humidiy greaer han 90% non-condensing; srong vibraions or knocks; exposure o coninuous waer sprays; exposure o aggressive and polluing amospheric agens (e.g.: sulphur and ammonia gases, saline mis, smoke) which may cause corrosion and/or oxidaion; srong magneic and/or radio frequency inerference (for example, near ransmiing anennae); exposure o direc sunligh and he elemens in general. The following warnings mus be observed when connecing he conrollers: incorrec connecion of he power supply may seriously damage he conroller; use cable ends suiable for he corresponding erminals. Loosen each screw and inser he cable ends, hen ighen he screws and genly pull he cables o check heir ighness. When ighening he screws, do no use auomaic screwdrivers, raher adjus ool ighening orque o less han 0.5Nm; separae as much as possible (by a leas 3 cm) he probe signal and digial inpu cables from inducive loads and power cables, o avoid any elecromagneic disurbance. Never lay power cables and probe cables in he same cable conduis (including hose for he elecrical panels). Do no insall he probe cables in he immediae viciniy of power devices (conacors, circui breakers or he like). Reduce he lengh of he sensor cables as much as possible, and avoid spirals around power devices; only use IP67 guaraneed probes as end defros probes; place he probes wih he verical bulb upwards, so as o faciliae drainage of any condensae. Remember ha hermisor emperaure probes (NTC) have no polariy, so he order he ends are conneced in is no imporan. Imporan: for 12 Vac and 12/24 Vac versions. When connecing a series of unis o he same imer, insulae all he conacs (digial inpus) galvanically, insering an inermediae relay for each conac. Cleaning he conroller When cleaning he conroller do no use ehanol, hydrocarbons (perol), ammonia and by-producs. Use neural deergens and waer. 2.9 Programming key (copy se-up) Programming key IROPZKEY00/A0 The programming key can load up o 7 differen parameer configuraions ono he conroller (he conroller operaing parameers plus 6 ses of cusomisable defaul parameers). The keys are plugged ino he connecor (4 pin AMP) available on he conrollers. All he operaions can be performed wih he conroller off. Imporan: a separae ransformer mus be used for each conroller, - NEVER connec muliple conrollers o he same ransformer.

When he alarm is acivaed: 1. he following acions occur: a signal is shown on he display ( IA ); he icon flashes; he buzzer is acivaed, if enabled; he alarm relay is acivaed, if seleced; 2. and he acuaors behave as follows: compressor: operaes depending on he values assigned o parameer A6 (sop compressor on exernal alarm). fans: coninue operaing according o he fan parameers ( F ). Noe when he compressor sops, he minimum compressor on ime ( c3 ) is ignored. 2 = Delayed exernal alarm The delayed exernal alarm is equivalen o he immediae exernal alarm, however wih he addiion of a delay A7 before he signal ( da ). Applicaion: his configuraion is especially useful for managing he low pressure alarm. In fac, when saring for he firs ime, he uni ofen deecs a low pressure alarm due o he environmenal condiions raher han a uni malfuncion. Seing a delay for he alarm (par. A7) will avoid false signals. In fac, by suiably calculaing he delay, if he low pressure is due o environmenal condiions (low emperaure), he alarm will be auomaically rese before he delay has elapsed. Noe if A7 =0 acivaion of he alarm does no cause he compressor o operae according o he values assigned o parameer A6 (sop compressor on exernal alarm); on he oher hand, he da signal is displayed, he icon flashes, he buzzer and he alarm relay (if seleced) are acivaed; he delayed exernal alarm is hus signal-only. 3 = Probe shown on he display (IR33M models) On hermomeer-only models, his seing selecion is used o exploi he digial inpu in order o show, on he display, he probe seleced by parameer /I or he firs enabled probe (see parameers /A2, /A3, /A4 ). In pracice, if he conac is open, he probe seleced by parameer /I is shown, whereas, if he conac is closed, he firs enabled probe is shown. Noe: if more han one digial inpu is configured as he probe selecion, he probe seleced by parameer /I is displayed when a leas one of he inpus is open. 3 = Enable defros (all oher models) Applicaion: any defross called when he conac is open remain pending unil he conac closes. The various possibiliies are shown below. A4 = 3 Conac Defros Open No enabled Closed Closed wihou reques from he conroller Closed wih in progress Enabled No performed When he digial inpu opens, he defros is immediaely sopped and he uni resars normal operaion (wihou performing he dripping or pos-dripping sages).

Tab. 5.f Noe his funcion is useful o preven defross on unis accessible o he public during opening imes. 4 = Sar defros from exernal conac Applicaion: his funcion is useful for performing defross in real ime. To perform he defross, connec a cyclical, mechanical or elecronic imer o he seleced digial inpu: a series of unis can be conneced o he same imer, seing differen values for parameer d5 (defros delay from mulifuncion inpu) o avoid simulaneous defross. Imporan: for 12 Vac and 12/24 Vac versions. When connecing a series of unis o he same imer, he bes soluion is o insulae all he conacs galvanically, insering an inermediae relay for each conac.

Parameer d8d is he alarm bypass ime afer he door is opened. If d8d=0, he alarm delay afer door open coincides wih he value of parameer d8. Seing A4 =5 manages he cold room door swich. The behaviour of he door swich depends on he saus of he ligh when he door is opened: 1. ligh off; 2. ligh on. 25
Case 1: ligh off when opening he door If he door is opened wih he ligh : he compressor and he evaporaor fans are swiched off; he ligh is swiched on (only on models fied wih a leas 1 auxiliary relay programmed as a ligh oupu); he reading displayed and he icon flash; he emperaure alarms are disabled. If he door remains open for a ime longer han d8 (d8d), he conroller resumes normal operaion: he compressor and he evaporaor fan are swiched on, if needed; he ligh is swiched off; he reading on he display flashes; he buzzer and he alarm relay are acivaed; he emperaure alarms are enabled wih he delay Ad. To sop he reading from flashing, close he door. When he door closes, he conroller resumes normal operaion, swiching off he ligh and enabling he emperaure alarm afer he delay ime d8. The compressor is re-sared, afer any se proecion imes (see he C parameers). Noe: if he ligh was previously swiched on manually, when he door is closed for he second ime, i is auomaically swiched off; even if he evaporaor fan is managed by he fan conroller (see he F parameers), he fans are forced o sop when he door is open. This algorihm resolves any problems relaing o fauls or malfuncions of he door swich. Door-swich Case 2: ligh on when opening he door The icon is on. If he door is open wih he ligh on, i is assumed he user eners he cold room, urning on he ligh before enering, closing he door behind him, and hen exis he room, closing he door a second ime. When he door is opened he firs ime: he compressor and he evaporaor fans are swiched off; he ligh says on (only on models fied wih a leas 1 auxiliary relay programmed as a ligh oupu); he reading is displayed and he icon flashes; he emperaure alarms are disabled. When he door is closed he firs ime, he conroller mainains he previous siuaion: he compressor and he evaporaor fans say off; he ligh says on; he reading is displayed and he icon flashes; he emperaure alarms are disabled. Door opened he second ime: no change. When he door is closed he second ime, he conroller resumes normal operaion, swiching off he ligh and enabling he emperaure alarm afer he delay ime d8. When he compressor re-sars, any se proecion imes mus elapse firs (see he C parameers). If, afer opening, he door remains open for a ime longer han d8 or d8d, he conroller resumes normal operaion: compressor and evaporaor fan swiched on if needed; ligh off; he reading on he display flashes; he buzzer and he alarm relay are acivaed; he emperaure alarms are enabled wih he delay Ad ; when he door closes, he high emperaure alarm bypass ime afer door open d8 is no se. To sop he reading from flashing, close he door. If, afer being closed for he firs ime, he door remains closed for longer han ime d8 or d8d, he conroller resumes normal operaion: compressor and evaporaor fan swiched on if needed; ligh off; he emperaure alarms are enabled wih he delay d8 ; he high emperaure alarm bypass ime afer door open d8 is se. If, afer he door is closed for he firs ime, he ligh is swiched off manually, he conroller resumes normal operaion: compressor and evaporaor fan swiched on if needed; ligh off; he emperaure alarms are enabled wih he delay d8 ; he high emperaure alarm bypass ime afer door open d8 is se. Fig. 5.c Noe: if more han one digial inpu is configured as a door swich, he door is considered open when a leas one of he inpus is open. 6 = Remoe On/Off The digial inpu may be programmed also as remoe /. When he conrol is in : he emperaure is displayed alernaing wih he message ; he inernal imer for parameer di is updaed. If di expires when he uni is, a defros is performed when he uni is swiched on again; he auxiliary relay se as auxiliary and ligh oupu is acive, he oher auxiliary oupus are off; he buzzer and he alarm relay are deacivaed; he conroller does no perform he conrol funcions, defross, coninuous cycle, signal emperaure alarms and all oher funcions; he compressor proecion imes are observed; When he conroller is swiched back on, all he funcions are re-acivaed, wih he excepion of: defros on sar-up; compressor and fan delay a power on. Noe: he / from exernal digial inpu has prioriy over he keypad and he supervisor; 7 = Curain swich If he inpu is seleced as a curain swich, he conroller modifies he se poin when he conac closes, adding he value of parameer r4 ; he new value is hen used for all he funcions relaing o he se poin (e.g. relaive high and low emperaure alarms, conrol wih dead band, conrol wih wo compressor seps ec.). For example when r4 =3.0 (defaul value), he se poin is increased by 3 degrees from he value used when he curain is open. r4 Auomaic nigh-ime se poin variaion 3-20 20 C/ F Tab. 5.g CMP/FAN S rd DIRECT DI OPEN Sv Fig. 5.d CMP/FAN S r4 rd DI CLOSED Sv 26

Seing A4 =8 manages he low pressure swich. The low pressure alarm LP is signalled when he low pressure swich is acivaed: during normal conrol (c7=0) wih he compressor on, or alernaively wih pump-down funcion configured (c7 >0), if he pump down valve is open and he compressor is on. The low pressure alarm signal is delayed by he ime se for parameer A7.

The defros call a sar-up has prioriy over acivaion of he compressor and he coninuous cycle. Defrosing when swiching conroller on may be useful in special siuaions. Example: here are frequen power failures in he sysem. In he even of a power failure, he insrumen reses he inernal clock ha calculaes he inerval beween wo defross, saring from zero again. If he frequency of he power failure were, in an exreme case, greaer han he defros frequency (e.g. a power failure every 8 hours, agains a defros every 10 hours) he conroller would never perform a defros. In a siuaion of his ype, i is preferable o enable 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. For sysems wih a large number of unis, if selecing defross a sar-up, afer a power failure, all he unis will sar a defros. This may cause volage overloads. 6.10 Evaporaor fans The evaporaor fans can be managed according o he emperaure measured by he defros and conrol probes.

The fan can be swiched off in he following siuaions: when he compressor is off (parameer F2); during he defros (parameer F3). During he dripping period (parameer dd > 0) and he pos-dripping period (parameer Fd > 0) he evaporaor fans are always off. This is useful o allow he evaporaor o reurn o emperaure afer defrosing, hus avoiding blowing warm ho and mois air ino he refrigeraor.

HACCP allows conrol of he operaing emperaure, recording any anomalies due o power failures or an increase in he emperaure due o oher causes (breakages, exreme operaing condiions, user errors, ec.). Two ypes of HACCP even are managed: ype HA alarms, high emperaure during he operaion; ype HF alarms, high emperaure afer power failure (blackou). When an alarm is recorded, he HACCP LED flashes, he display shows he alarm code, he alarm is saved and he alarm relay and buzzer are acivaed. Example: display afer HA error on ir33+ and alarm rese: Noe: o mue he buzzer press Prg/mue. 41

8.5 Alarm parameers Alarm parameers and acivaion AAL (AH) is used o deermine he acivaion hreshold for he low (high) emperaure alarm LO (HI). The value se for AL (AH) is coninuously compared agains he value measured by he conrol probe. Parameer Ad represens he alarm acivaion delay, in minues; he low emperaure alarm (LO) is acivaed only if he emperaure remains below he value of AL for a ime greaer han Ad. The alarm may relaive or absolue, depending on he value of parameer A1. In he former case (A1=0), he value of AL indicaes he deviaion from he se poin and hus he acivaion poin for he low emperaure alarm is: se poin - AL. If he se poin changes, he acivaion poin also changes auomaically. In he laer case (A1=1), he value of AL indicaes he low emperaure alarm hreshold. The low emperaure alarm acive is signalled by he buzzer and LO shown on he display. The same applies o he high emperaure alarm (HI), wih AH insead of AL.

A0 represens he hyseresis beween he alarm acivaion value and deacivaion value; if Prg/mue is pressed when he value measured is above one of he hresholds, he buzzer is immediaely mued, while he alarm code and he alarm oupu, if se, remain acive unil he value measured is ouside of he acivaion hreshold. For delayed alarms from digial inpu (A4=2, code da), he conac mus remain open for a ime greaer han A7. In he case of an alarm even, a couner sars and generaes an alarm when reaching he minimum ime A7. If during he coun he value measured reurns wihin he hreshold or he conac closes, he alarm is no signalled and he coun is rese. When a new alarm condiion occurs, he coun sars from 0 again. Parameer A6 has a similar meaning o parameer c4 (duy seing). If an exernal alarm occurs (immediae or delayed) he compressor works for a ime equal o he value se for A6 and remains off for a fixed ime of 15 minues.
