2. GENERAL DESCRIPTION
Models XW60LT and XW60LRT, format 38x185mm, are microprocessor based controllers, suitable
for applications on medium or low temperature ventilated refrigerating units. They have 4 relay outputs
to control compressor, fan, defrost, which can be either electrical or reverse cycle (hot gas) and a
fourth configurable output. They could be provided with a Real Time Clock which allows programming
of up to 6 daily defrost cycles, divided into holidays and workdays. A “Day and Night” function with
two different set points is fitted for energy saving. They are also provided with up to four NTC or PTC
probe inputs, the first one for temperature control, the second one, to be located onto the evaporator,
to control the defrost termination temperature and to managed the fan. One of the digital inputs can
operate as third temperature probe. The fourth probe is used to signal the condenser temperature
alarm or to display a temperature. NOTE: the fourth probe is available only for XW60LT models.
The HOT KEY output allows to connect the unit, by 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 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.
Time
Temper.
Compr.
SET
ON
In case of fault in the thermostat probe the start and stop of the compressor are timed through
parameters Con and CoF.
3.2 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 depends 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 hours 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 defrost dripping time is started, its length is set in the Fdt parameter. With Fdt=0 the
dripping time is disabled.
3.3 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;
-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.
After defrost, there is a timed fan delay allowing for drip time, set by means of the Fnd parameter.
An additional parameter 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.
3.3.1 Forced activation of evaporator fans
This function, managed by the FCt parameter, is designed to avoid short cycles of evaporator fans,
which could happen when the controller is switched on or after a defrost (when the room air warms
the evaporator). If the temperature difference between the evaporator and the room probes is higher
than the value set in the FCt parameter the fans are switched on. With FCt=0 this function is
disabled.
3.3.2 Fans cyclic activation with compressor off.
When FnC=C-n or C-Y (fans working in parallel with the compressor), by means of the Fon and FoF
parameters the fans can carry out on and off cycles even if the compressor is switched off. When the
compressor is stopped the fans go on working for the Fon time. With Fon=0 the fans remain always
off, when the compressor is off.
3.4 AUXILIARY OUTPUT CONFIGURATION
The functioning of the auxiliary relay can be set by the oAx parameters according to the kind of
application. In the following paragraph the possible settings are explaided.
3.4.1 Auxiliary thermostat
A possible use is the anti condensing heater, with the possibility of switching it on and off also by
keyboard.
Parameters involved:
-ACH: kind of regulation for the auxiliary relay: Ht: heating; cL: cooling;
-SAA: set point for auxiliary relay;
-SHy: differential for auxiliary relay;
-ArP: probe for auxiliary relay;
-Sdd: auxiliary output off during defrost.
The differential is given by the SHy parameter.
The auxiliary relay can be switched on also by using the AUX button. In this case it remains on till it’s
manually switched off.
NOTE: If oAx=AUS and ArP=nP (no probe for auxiliary output), the AUX relay can be activated only
by pushing the AUX button of the keyboard.
3.4.2 On/off relay – oAx = onF
In this case the relay is activated when the controller is turned on and de-activated when the controller
is turned off.
3.4.3 Neutral zone regulation
With oAx=db the AUX relay can control a heater element to perform a neutral zone action.
-output oAx cut in = SET-HY;
-output oAx cut out = SET.
3.4.4 Second compressor
With oAx=CP2, the AUX relay operates as second compressor: it is activated in parallel with the
relay of the first compressor, with a proper activation delay (set in the AC1 parameter). Both the
compressors are switched off at the same time.
3.4.5 Alarm relay
With oAx=ALr the AUX relay operates as alarm relay. It is activated every time an alarm happens. Its
status depends on the tbA parameter:
-tbA=Y: the relay is silenced by pressing any key;
-tbA=n: the alarm relay remains on until the alarm condition recovers.
3.4.6 Night blind management during energy saving cycles
With oAx=HES the AUX relay operates to manage the night blind: the relay is energised when the
energy saving cycle is activated by digital input, frontal button or RTC (optional).
4. FRONT PANEL COMMANDS

9. DIGITAL INPUTS
The first digital input (XW60LT: terminals 13-14; XW60LRT: terminals 14-15) is enabled if P3P=n.
With P3P=n and i1F=i2F the second digital input will be disabled.
The free voltage digital inputs are programmable by the i1F and i2F parameters.
9.1 GENERIC ALARM (i1F or i2F = 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 de-
activated.
9.2 SERIOUS ALARM MODE (i1F or i2F = 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 de-
activated.
9.3 PRESSURE SWITCH (i1F or i2F = PAL)
If during the interval time set by did parameter, the pressure switch has reached the number of
activation of the nPS parameter; the “CA” pressure alarm message 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.
9.4 DOOR SWITCH INPUT (i1F or i2F = 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 if rtr=YES. The alarm stops as
soon as the external digital input is disabled again. With the door open, the high and low temperature
alarms are disabled.
9.5 START DEFROST (i1F or i2F = dEF)
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 wait until the MdF safety
time is expired.
9.6 SWITCH THE AUXILIARY RELAY (i1F or i2F = AUS)
With oAx=AUS the digital input will change the status of the auxiliary relay.
9.7 INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F or i2F=Htr)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
9.8 ENERGY SAVING (i1F or i2F = 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 ON OFF FUNCTION (i1F or i2F = onF)
To switch the controller on and off.
9.10 DIGITAL INPUTS POLARITY
The digital input polarity depends on the i1P and i2P parameters.
-i1P or i2P =CL: the input is activated by closing the contact.
-i1P or i2P=OP: the input is activated by opening the contact.
10. TTL SERIAL LINE – FOR MONITORING SYSTEMS
The TTL serial line, available through the HOT KEY connector, allows by means of the external
TTL/RS485 converter, XJ485-CX, to connect the instrument to a monitoring system ModBUS-RTU
compatible such as the X-WEB500/3000/300.
11. X-REP OUTPUT – OPTIONAL
As optional, an X-REP can be connected to the instrument, trough the dedicated connector.
To connect the X-REP to the
instrument the following
connectors must be used
CAB/REP1(1m), CAB/REP2
(2m), CAB/REP5 (5m),
12. INSTALLATION AND MOUNTING
The XW60LT shall be mounted on vertical panel, in a 150x31 mm hole, and fixed using the special
brackets supplied with the controllers. The temperature range allowed for correct operation is 0 to
60°C. Avoid places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The
same recommendations apply to probes. Let the air circulate by the cooling holes.
12.1 CUT OUT
13. ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to
2.5 mm2 for the digital and analogue inputs. Relays and power supply have a Faston connection
(6.3mm). Heat-resistant cables have to be used. Before connecting cables make sure the power
supply complies with the instrument’s requirements. Separate the probe cables from the power supply
cables, from the outputs and the power connections. Do not exceed the maximum current allowed on
each relay, in case of heavier loads use a suitable external relay.
N.B. Maximum current allowed for all the loads is 20A.
13.1 PROBE CONNECTION
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.
14. HOW TO USE THE HOT KEY
