4. ELECTRICAL CONNECTIONS
4.1 WIRING BEST PRACTICES
The following information describes the wiring guidelines and best practices which should be observed when using the
equipment described in this manual.
DANGER
RISK OF ELECTRIC SHOCK, EXPLOSION OR ELECTRIC ARC
• Only use electrically insulated measuring devices and equipment.
• Do not install the equipment while the power supply is connected.
• Switchoffallequipment,includingconnecteddevices,beforeinstallingoruninstallingthedevice.
• Alwaysuseacorrectlycalibratedvoltmetertocheckthesystemisswitchedoff.
• Do not touch the unshielded components or the terminals while they are live.
• Donotopen,disassemble,repairormodifytheproduct.
• Do not expose the equipment to liquids or chemicals.
• Before applying voltage to the equipment:
• Makesureallprotectiveelements,suchascovers,hatchesandgrilles,arefittedand/orclosed.
• Checkallwiringconnections.
4.1.1 Wiring guidelines
Whenwiringthecontrollers,observethefollowinginstructions:
• TheI/Oandcommunicationwiringmustbekeptseparatefromthepowersupplywiring.Thesetwotypesofwiringmust
be routed in separate ducts.
• Makesuretheoperatingenvironmentandconditionsfallwithinthespeciedvalues.
• Usewireswiththecorrectdiameter,suitedtothevoltageandcurrentrequirements.
• Use copper conductors (compulsory).
• Use shielded twisted pair cables for analogue/digital I/O connections.
Use correctly earthed shielded cables for all analogue inputs or outputs and for communication connections. If shielded cables
arenotusedfortheseconnections,electromagneticinterferencecouldcausethesignaltodeteriorate.Deterioratedsignals
can lead to unpredictable operation of the controller or modules and connected equipment.

6. DEFROST
6.1 INTRODUCTION
Defrosting removes ice from the surface of the evaporator. The defrost cycle consists of 4 phases:
1. Defrost;
2. Pre-dripping;
3. Dripping;
4. Post-dripping.
Attheendofeachphase,thecontrollerstartsupthenextone;whentheentiredefrostcycleisfinished,thecontrollerreturns
to normal operation.
With d0=0,defrostissettomanualoperation.Forautomaticmode,setd0 > 0.
6.1.1 Types of defrost
The controller can operate with two different types of defrost:
• Modular;
• Standard.
6.2 ADAPTIVE DEFROST
Adaptivedefrostissetbythefollowingparameters:
Par. Description MU Range
d0 Automaticdefrostinterval.0= Manual defrost only
N.B.: if d8=3,themaximumintervalisconsidered. h 0... 99
d8
Defrost interval count mode. 0= Hours device ON; 1= Hours compressor ON;
2= Hours evaporator temperature < d9; 3=Adaptive;4= In real time (RTC).
--- 0...4

d19 Adaptivedefrostthreshold(relativetooptimalevaporationtemperature). °C/°F 0.0...40.0
d22 Evaporation threshold for adaptive defrost interval count (relative to optimal evaporation
temperature). °C/°F -10.0...10.0
6.2.1 Defrost with Hours device ON
Defrost with Hours device ON is set with the following parameters:

N.B.: if d8=3,themaximumintervalisconsidered.
h 0... 99

Operation
The controller begins counting the operating hours from when the device is switched on. If d0 >0 and d8=0,oncetimed0 has
elapsed,thedevicecarriesoutdefrostofthedurationofd3.
The d0 count is set to zero (and restarts) every time defrost starts up.

d22 Evaporation threshold for adaptive defrost interval count (relative to optimal evaporation
temperature). °C/°F -10.0...10.0
Operation
Adaptivedefrostworksbydividingtemperatureregulationintotwophases:
• Calibration phase and;
• Normalworkingphase.
Calibration phase
Whentherefrigeratingmachineisswitchedonorafterdefrost,thedevicecalculatestheidealevaporatorworkingtemperature
to reach the setpoint SP.
Normal working phase
Duringthenormalworkingphase,thedeviceaddsupthecompressorONtimeswhilethetemperaturereadbyPb2islower
than the ideal evaporator temperature.
Defrost is activated if:
• The count exceeds the time d18;
• The temperature read by Pb2 goes below the ideal temperature calculated of a threshold d19.
