1. GENERAL WARNING

1.1 PLEASE READ BEFORE USING THIS MANUAL• This manual is part of the product and should be kept near the instrument for

easy and quick reference.• The instrument shall not be used for purposes different from those described

hereunder. It cannot be used as a safety device.• Check the application limits before proceeding.

1.2 SAFETY PRECAUTIONS• Check the supply voltage is correct before connecting the instrument.• Do not expose to water or moisture: use the controller only within the operating

limits avoiding sudden temperature changes with high atmospheric humidity toprevent formation of condensation

• Warning: disconnect all electrical connections before any kind of maintenance.• Fit the probe where it is not accessible by the End User. The instrument must

not be opened.• In case of failure or faulty operation send the instrument back to the distributor

or to “Dixell s.r.l.” (see address) with a detailed description of the fault.• Consider the maximum current which can be applied to each relay (see

Technical Data).• Ensure that the wires for probes, loads and the power supply are separated

and far enough from each other, without crossing or intertwining.• In case of applications in industrial environments, the use of mains filters (our

mod. FT1) in parallel with inductive loads could be useful.

2. GENERAL DESCRIPTIONModel XR30C, format 32 x 74 mm, is a digital termostat with off cycle defrostdesigned for refrigeration applications at normal temperature. It provides two relayoutputs, one for the compressor, the other one can be used for alarm signalling oras auxiliary output. The probe input can be selected between PTC or NTC. Theinstrument has a digital input, for alarm signalling, for switching the auxiliary outputor for start a defrost cycle.

3. CONTROLLING LOADS

3.1 COMPRESSORThe regulation is performed according to the temperature measured by thethermostat probe with a positive differential from the set point: if the temperatureincreases and reaches set point plus differential the compressor is started and thenturned off when the temperature reaches the set point value again.

In case of fault in the thermostat probe the start and stop of the compressor aretimed through parameters “COn” and “COF”.

3.2 DEFROSTDefrost is performed through a simple stop of the compressor. Parameter “IdF”controls the interval between defrost cycles, while its length is controlled byparameter “MdF”.

4. FRONT PANEL COMMANDS

7. PARAMETERSNOTE: the parameters preceded by dots are in the Hidden Menu.REGULATIONHy Differential: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point.

Compressor Cut IN is Set Point Plus Differential (Hy). Compressor Cut OUT iswhen the temperature reaches the set point.

• LS Minimum set point: (- 50°C÷SET/-58°F÷SET): Sets the minimumacceptable value for the set point.

• US Maximum set point: (SET÷110°C/ SET÷230°F). Set the maximumacceptable value for set point.

Ot Thermostat probe calibration: (-12.0÷12.0°C;-120÷120°F) allows to adjust possible offset of the thermostat probe.

• OdS Outputs activation delay at start up: (0÷255min) This function isenabled at the initial start up of the instrument and inhibits any output activationfor the period of time set in the parameter.

AC Anti-short cycle delay: (0÷50 min) minimum interval between the compressorstop and the following restart.

• CCt Compressor ON time during continuous cycle: (0.0÷24.0h; res. 10min)Allows to set the length of the continuous cycle: compressor stays on withoutinterruption for the CCt time. Can be used, for instance, when the room is filledwith new products.

• COn Compressor ON time with faulty probe: (0÷255 min) time during whichthe compressor is active in case of faulty thermostat probe. With COn=0compressor is always OFF.

• COF Compressor OFF time with faulty probe: (0÷255 min) time during whichthe compressor is OFF in case of faulty thermostat probe. With COF=0compressor is always active.

CH Type of action: CL = cooling; Ht = heating.DISPLAY• CF Temperature measurement unit:

°C=Celsius; °F=Fahrenheit. WARNING: When the measurement unit ischanged the SET point and the values of the parameters Hy, LS, US, Ot, ALUand ALL have to be checked and modified if necessary).

rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows decimal point display.DEFROSTIdF Interval between defrost cycles: (0÷120h) Determines the time interval

between the beginning of two defrost cycles.MdF (Maximum) length for defrost: (0÷255min) When P2P = n, (not evaporator

probe: timed defrost) it sets the defrost duration, when P2P = y (defrost endbased on temperature) it sets the maximum length for defrost.

• dFd Temperature displayed during defrost: (rt = real temperature; it =temperature at defrost start; SEt = set point; dEF = “dEF” label)

• dAd MAX display delay after defrost: (0÷255min). Sets the maximum timebetween the end of defrost and the restarting of the real room temperaturedisplay.

ALARMS• ALC Temperature alarms configuration: (Ab; rE)

Ab= absolute temperature: alarm temperature is given by the ALL or ALUvalues. rE = temperature alarms are referred to the set point. Temperaturealarm is enabled when the temperature exceeds the “SET+ALU” or “SET-ALL”values.

ALU MAXIMUM temperature alarm: (SET÷110°C; SET÷230°F) when thistemperature is reached the alarm is enabled, after the “ALd” delay time.

ALL Minimum temperature alarm: (-50.0 ÷ SET°C;-58÷230°F when this temperature is reached the alarm is enabled, after the“ALd” delay time.

• ALd Temperature alarm delay: (0÷255 min) time interval between thedetection of an alarm condition and alarm signalling.

SECOND RELAY AND DIGITAL INPUT• tbA Alarm relay silencing (with oAC=ALr):

(n= silencing disabled: alarm relay stays on till alarm condition lasts, y=silencing enabled: alarm relay is switched OFF by pressing a key during analarm).

OA1 Second relay configuration: ALr: alarm; LHt: auxiliary; onF: always on; dEF:do not select it!.; FAn: do not select it!.;

AoPAlarm relay polarity: it set if the alarm relay is open or closed when an alarmhappens. CL= the relay is closed; oP = the relay is open

i1P Digital input polarity: oP: the digital input is activated by opening the contact;CL: the digital input is activated by closing the contact.

i1F Digital input configuration:EAL = external alarm: “EA” message is displayed; bAL = serious alarm “CA”message is displayed. PAL = pressure switch alarm, “CA” message isdisplayed; dor = door switch function; dEF = activation of a defrost cycle; LHt=switch on the second relay if oA1=LHt; Htr = kind of action inversion (cooling– heating).

did: (0÷255 min)with i1F= EAL or i1F = bAL digital input alarm delay: delay between thedetection of the external alarm condition and its signalling.with i1F= dor: door open signalling delaywith i1F = PAL: time for pressure switch function: time interval to calculatethe number of the pressure switch activation.

nPS Pressure switch number: (0 ÷15) Number of activation of the pressureswitch, during the “did” interval, before signalling the alarm event (I2F= PAL).If the nPS activation in the did time is reached, switch off and on theinstrument to restart normal regulation.

• odc Compressor status when open door: no, Fan = normal; CPr, F_C =Compressor OFF

OTHERPbC Type of probe: it allows to set the kind of probe used by the instrument: PbC

= PBC probe, ntC = NTC probe.• rEL Software release for internal use.• Ptb Parameter table code: readable only.

8. DIGITAL INPUTThe free contact digital input is programmable in five different configurations by the“i1F” parameter.

������ �������������� ������������������ ����������

8.1 DOOR SWITCH INPUT (i1F = dor)It signals the door status and the corresponding relay output status through the“odc” parameter:

no, Fan = normal (any change);CPr, F_C = Compressor OFF;

Since the door is opened, after the delay time set through parameter “did”, the dooralarm is enabled, the display shows the message “dA” and the regulation restarts.The alarm stops as soon as the external digital input is disabled again. With thedoor open, the high and low temperature alarms are disabled.

8.2 GENERIC ALARM (i1F = EAL)As soon as the digital input is activated the unit will wait for “did” time delay beforesignalling the “EAL” alarm message. The outputs status don’t change. The alarmstops just after the digital input is de-activated.

8.3 SERIOUS ALARM MODE (i1F = bAL)When the digital input is activated, the unit will wait for “did” delay before signallingthe “CA” alarm message. The relay outputs are switched OFF. The alarm will stopas soon as the digital input is de-activated.

8.4 PRESSURE SWITCH (i1F = PAL)If during the interval time set by “did” parameter, the pressure switch has reachedthe number of activation of the “nPS” parameter, the “CA” pressure alarm messagewill be displayed. The compressor and the regulation are stopped. When the digitalinput is ON the compressor is always OFF.If the nPS activation in the did time is reached, switch off and on theinstrument to restart normal regulation.

8.5 SWITCHING SECOND RELAY ON (i1F = LHt)With oA1= LHt it switches on and off the second relay.

8.6 START DEFROST (i1F = dFr)It starts a defrost if there are the right conditions. After the defrost is finished, thenormal regulation will restart only if the digital input is disabled otherwise theinstrument will wait until the “MdF” safety time is expired.

8.7 INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F = Htr)This function allows to invert the regulation of the controller: from cooling to heatingand viceversa.

8.8 DIGITAL INPUTS POLARITYThe digital input polarity depends on the “i1P” parameter.i1P=CL: the input is activated by closing the contact.i1P=OP: the input is activated by opening the contact

9. INSTALLATION AND MOUNTINGInstrument XR30C shall be mounted on verticalpanel, in a 29x71 mm hole, and fixed using thespecial bracket supplied.To obtain an IP65 protection grade use the frontpanel rubber gasket (mod. RG-C) as shown infigure.

The temperature range allowed for correct operation is 0÷60 °C. Avoid placessubject to strong vibrations, corrosive gases, excessive dirt or humidity. The samerecommendations apply to probes. Let air circulate by the cooling holes.

10. ELECTRICAL CONNECTIONSThe instrument is provided with screw terminal block to connect cables with a crosssection up to 2,5 mm2. Before connecting cables make sure the power supplycomplies with the instrument’s requirements. Separate the probe cables from thepower supply cables, from the outputs and the power connections. Do not exceedthe maximum current allowed on each relay, in case of heavier loads use a suitableexternal relay.

10.1 PROBE CONNECTIONThe probes shall be mounted with the bulb upwards to prevent damages due tocasual liquid infiltration. It is recommended to place the thermostat probe away fromair streams to correctly measure the average room temperature. Place the defrosttermination probe among the evaporator fins in the coldest place, where most ice is

formed, far from heaters or from the warmest place during defrost, to preventpremature defrost termination.

11. HOW TO USE THE HOT KEY

11.1 HOW TO PROGRAM A HOT KEY FROM THEINSTRUMENT (UPLOAD)1. Program one controller with the front keypad.2. When the controller is ON, insert the “Hot key” and push �� key; the "uPL"

message appears followed a by flashing “End”3. Push “SET” key and the End will stop flashing.4. Turn OFF the instrument remove the “Hot Key”, then turn it ON again.

NOTE: the “Err” message is displayed for failed programming. In this case pushagain �� key if you want to restart the upload again or remove the “Hot key” to abortthe operation.

11.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY(DOWNLOAD)1. Turn OFF the instrument.2. Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn

the Controller ON.3. Automatically the parameter list of the “Hot Key” is downloaded into the

Controller memory, the “doL” message is blinking followed a by flashing“End”.

4. After 10 seconds the instrument will restart working with the new parameters.5. Remove the “Hot Key”..

NOTE the message “Err” is displayed for failed programming. In this case turn theunit off and then on if you want to restart the download again or remove the “Hotkey” to abort the operation.

12. ALARM SIGNALSMessage Cause Outputs“P1” Room probe failure Compressor output according

to par. “Con” and “COF”“HA” Maximum temperature alarm Outputs unchanged.“LA” Minimum temperature alarm Outputs unchanged.“dA” Door open Regulation restarts“EA” External alarm Output unchanged.“CA” Serious external alarm (i1F=bAL) All outputs OFF.“CA” Pressure switch alarm (i1F=PAL) All outputs OFF

12.1 ALARM RECOVERYProbe alarm “P1” starts some seconds after the fault in the related probe; itautomatically stops some seconds after the probe restarts normal operation. Checkconnections before replacing the probe.Temperature alarms “HA” and “LA” automatically stop as soon as the thermostattemperature returns to normal values and when defrost starts.Alarms “EA” and “CA” (with i1F=bAL) recover as soon as the digital input isdisabled.Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
