2 GENERAL DESCRIPTION
Model XW60K is microprocessor based contro ller suitable for applications on medium or low temperature refrigerating units. It has to be connected by me ans of a two-wir e cable ( 1mm) at a distance of up to 30 meters to the keyboard T620T or T620 or V620 or CX620. It is provided with four relay outputs to control compr essor, defrost - which can be either electrical or hot gas - the evaporator fans and light. It is also provided with 4 NTC or PTC probe inputs, one for temperature control, one to control the defrost end temperature of the evaporator and the third and fourth to control condenser temperature or to display another temperature. The HOT KEY output allows to connect the unit, b y means of the external module XJ485-CX, to a network line ModBUS-RTU compatible such as the dIXEL monitoring units of X-WEB family. It allows to program the controller by means the HOT KEY programming keyboard. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard.
3 CONTROLLING LOADS
3.1 THE COMPRESSOR
The regulation is performed according to the temperature measured by the thermostat probe with a positive differential from the set point: if the temperature increases and reaches set point plus differential the compressor is started and then turned 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 are timed through parameters Con and CoF. The relay of the second compressor is activated in parallel with the relay of the first compressor, with a possible delay set in the AC1 parameter. Both the compressors ar e switched off at the same time.
3.2 FAST FREEZING
When defrost is not in progress, it can be activated by holding the UP key pressed for about 3 sec. The compressor operates to maintain the CCS set point for the time set through the CCt parameter. The cycle can be terminated before the end of the set time using the same activation key UP for 3 sec.
3.3 DEFROST
Two defrost modes are available through the tdF parameter: defrost through electrical heater (tdF = EL) and hot gas defrost (tdF = in).
The defrost interval depend s on the presence of the RTC (optional). If the RTC is present is controlled by means of parameter EdF:
- EdF=in: a defrost starts after elapsing the idF time (standard way for controller without RTC). EdF=rtC: defrosts are scheduled by using a real time clock system, depending on the h ours set in the
parameters Ld1..Ld6, during workdays, and in Sd1…Sd6 during holidays. Other parameters are used to control defrost cycles: its maximum length (MdF) and two defrost modes: timed or controlled by the evaporator’s probe (P2P).
At the end of d efrost dripping time is started, its length is set in the Fdt parameter. With Fdt=0 the dripping time is disabled.
3.4 CONTROL OF EVAPORATOR FANS
The fan control mode is selected by means of the FnC parameter: FnC = C_n: fans will switch ON and OFF with the compressor and not run during defrost; FnC = o_n fans will run even if the compressor is off, and not run during defrost; After defrost, there is a timed fan delay allowing for drip time, set by means of the Fnd parameter. FnC = C_Y fans will switch ON and OFF with the compressor and run during defrost; FnC = o_Y fans will run continuously also during defrost.
An additional p arameter FSt provides the setting of temperature, detected by the evaporator probe, above which the fans are always OFF. This is used to make sure circulation of air only if his temperature is lower than set in FSt.
3.4.1 Forced activation for fans
This function, managed by the FCt parameter, is designed to avoid short cycles of fans, that could happen when the controller is switched on or after a defrost, when the room air warms the evaporator. If the difference between the evaporator temperature and the room temperature is higher than t he FCt value, the controller will activate the fans. This function is disabled if FCt=0.
3.4.2 Timed activation of the fans when the compressor is off.
When FnC=C-n or C-Y (fans in para llel to the compressor), the fans will be able to carry out on and off cycles even if the c ompressor is switched off. The on and off interval of time follow the Fon and FoF parameters. When the compressor is stopped the fans will go on working for the Fon time. On the other side, with Fon=0 the fans will stay always off when the compressor is off.
4 SPECIAL FUNCTIONS
By means of the parameter oA3, it’s possible to configure the functions of the light re lay (22-23), as described in the following paragraphs:
4.1 LIGHT RELAY (FACTORY SETTING, OA3 = LIG)
By setting oA3=Lig the relay will work as light relay, it is switched on and off by the light button on the keyboard and is affected by status of the digital input when i1F=dor.
4.2 SECOND COMPRESSOR MANAGEMENT (OA3 = CP2)
By setting oA3=CP2, the relay at terminals 22-23 will operate as “second compressor”. It will b e activated in parallel with the relay of the first compressor, with a possible delay set in the AC1 parameter (seconds). Both the compressors are switched off at the same time.
4.3 ON –OFF RELAY (OA3 = ONF)
By setting oA3=onF, the relay will operate as “on-off” relay: it will be activated when the controller is switched on and it will be switched off when the controller is in stand-by status.
4.4 AUXILIARY RELAY (OA3 = AUS)
By setting oA3=AUS, the relay 22-23 will work as auxiliary thermostat (ex. anti condensing heater). Parameters involved:
- ACH (cL, Ht): Kind of regulation for the auxiliary relay: Ht = heating / CL = cooling;
- SAA (-50÷150) Set point for auxiliary relay
- SHy (0÷25.5°C) Differential for auxiliary output. With ACH = CL: aux relay cut in is SAA+SHy, cut out SAA. With ACH = Ht: aux relay cut in is SAA-SHy, cut out SAA.
- ArP (nP, P1, P2, P3, P4) Probe for auxiliary relay
- Sdd (n, Y) Auxiliary output working during defrost
4.5 ALARM RELAY (OA3 = ALR)
By setting oA3=ALr the relay will work as alarm relay, it is switched on when an alarm happens. Parameters involved:
- tbA (n, y) Alarm relay silencing
- AoP (cL; oP) Alarm relay polarity
4.6 NEUTRAL ZONE (OA3 = DB)
By setting oA3=db the controller will perform a “neutral zone” regulation. The heating e lement has to be connected to the oA3 relay (22-23) If the temperature increases and reaches set point plus differential (HY) the compressor is started and then turned off when the temperature reaches the set point value again. If the temperature decreases and reaches the set point minus differential (HY) the oA3 output (heater) is switched on and then turned OFF when the temperature reaches again the set point.

did Digital input 1 alarm delay: (0 to 255 mi n) delay between the detection of the external
alarm condition and its signalling.
When i1F= PAL, it is the interval of time to calculate the number of pressure switch
nPS Number of pressure switch activation: (0 to 15) Number of activation, during the did or
d2d interval, before signalling an alarm event (i1F, i2F=PAL).
If the nPS activation during did or d2d time is reached, switch off and on the instrument to
restart normal regulation.
odC Compressor status when open door: (no; FAn; CPr;F_C;) no = normal;
FAn = normal; CPr = compressor OFF, F_C = compressor OFF.
rrd Outputs restart after door open alarm: (n; Y) n = outputs follow the odC parameter.
Y = outputs restart with a door open alarm. LES Light off during Energy Saving status: n; Y. HES Delta temperature during an Energy Saving cycle: (-30.0 to 30.0°C; -54 to 54°F) it
sets the increasing value of the set point [SET+HES] during the Energy Saving cycle.

continuous cycle.
rEL Software release for internal use. Ptb Parameter table code: readab le only.
9 DIGITAL INPUT
The free voltage digital input is programmable in different configurations by the i1F parameter.
9.1 DOOR SWITCH INPUT (I1F = DOR)
It signals the door status and the corresponding relay output status through the odC parameter: no = normal (any change); Fan = Fan OFF; CPr = Compressor OFF; F_C = Compressor and fan OFF. Since the door is opened, after the delay time set through parameter did, the door alarm is enabled, the display shows the message “dA” and the regulation restarts is rtr = yES. The alarm stops as soon as the external digital input is d isabled again. With the door open, the high and low temperature alarms are disabled.
9.2 GENERIC ALARM (I1F = EAL)
As soon as the digital input is activated the unit will wait for did time delay before signalling the “EAL” alarm message. The outputs status doesn’t change. The alarm stops just after the digital input is de­activated.
9.3 SERIOUS ALARM MODE (I1F = BAL)
When the digital input is activated, the unit will wait for did delay before signalling the “CA” alarm message. The relay outputs are switched OFF . The alarm will stop as soon as the digital input is de­activated.
9.4 PRESSURE SWITCH (I1F = PAL)
If during the interval time set b y did parameter, the pressure switch has reached the number of activation of the nPS parameter, the “CA” pressure alarm mess age will be displayed. The compressor and the regulation are stopped. When the digital input is ON the compressor is always OFF. If the
nPS activation in the did time is reached, switch off and on the instrument to restart normal regulation.
9.5 AUXILIARY OUTPUT SWITCHING (I1F =AUS)
With oA3=AUS and i1F=AUX it switches the fourth relay (22-23).
9.6 START DEFROST (I1F = DFR)
It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will restart only if the digital input is disabled otherwise the instrument will w ait until the MdF safety time is expired.
9.7 KIND OF ACTION: HEATING OR COOLING (I1F = HTR)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
9.8 ENERGY SAVING (I1F = ES)
The Energy Saving function allows to change the set point value as the result of the SET+HES (parameter) sum. This function is enabled until the digital input is activated.
9.9 DIGITAL INPUTS POLARITY
The 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

11 ELECTRICAL CONNECTIONS
XW60K is provided with screw terminal blocks to connect cables with a cross section up to 2.5 mm2 for
the RS485 (optional) and the keyboard. To connect the other inputs, power supply and relays, XW60K is provided with Faston connections (6.3mm). Heat-resistant cables ha ve to be used. Before connecting cables make sure the power supply comp lies with the instrument’s requirements. Separate the probe c ables from the power supply cables, from the outputs and the power c onnections. Do not exceed the maximum current allowed on e ach relay, in case of heavier loads use a s uitable e xternal relay.
NOTE: the maximum current allowed for all the loads is 20A.
11.1 PROBE CONNECTIONS
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is recommended to place the thermostat probe away from air streams to correctly measure the average room temperature. Place the defrost termination 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 prevent premature defrost termination.
12 TTL/RS485 SERIAL LINE
The TTL connector allows, by m eans of the external module TTL/RS485 (XJ485CX), to connect the unit to a network line ModBUS-RTU compatible as the dIXEL monitoring system. The same TTL connector is used to upload and download the parameter list of the “HOT-KEY”.
13 HOW TO: USE OF THE PROGRAMMING “HOT KEY”
13.1 PROGRAM A HOT-KEY FROM AN INSTRUMENT (UPLOAD)
1. Program one controller with the front ke ypad.
2. When the controller is ON, insert the “HOT-KEY” and push UP button; the “uPL” message appears followed a by a flashing “End” label.
3. Push SET button and the “End” will stop flashing.
4. Turn OFF the instrument, remove the “HOT-KEY” and then turn it ON again.
NOTE: the “Err” message appears in case of a failed programming operation. In this case push again button if you want to restart the upload ag ain or remove the “HOT-KEY” to abort the operation.
13.2 PROGRAM AN INSTRUMENT BY USING A HOT-KEY (DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a pre-programmed HOT-KEY into the 5-PIN receptacle and then turn the Controller ON.
3. The parameter list of the “HOT-KEY” will be automatically downloaded into the Controller memory. The “doL” message will blink followed a by a flashing “End” label.
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 the unit off and then on if you want to restart the download again or remove the “HOT-KEY” to abort the operation.

To reset the “EE” alarm and restart the normal functioning press any key, the “rSt” message is displayed for about 3 sec.
14.1 SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key. Buzzer is mounted in the keyboard and it is an option.
14.2 “EE” ALARM
The dIXEL instruments are provided with an internal check for the data integrity. The “EE” alarm flashes when a failure in the memory data occurs. In such cases the alarm output is enabled.
14.3 ALARM RECOVERY
Probe alarms: “P1” (pro be1 faulty), “P2”, “P3” and “P4”; they automatic ally stop 10 sec after the probe restarts normal operation. Check connections before rep lacing the probe. Temperature alarms “HA”, “LA” “HA2” and “LA2” automatically stop as soon as the temperature returns to normal values. Alarms “EA” and “CA” (with i1F=b AL) recover as soon as the digital input is disabled. Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
