Battery backup
Model XR30CX, format 32x74mm, is a digital thermostat with off cycle defrosting function designed for
refrigeration applications. It provides two relay outputs, one for the compressor and the other one for
alarm signalling. It is also provided with a PT1000 or PTC probe input for temperature control.
Moreover, the digital input can operate as third temperature probe.
The battery-backup version is also provided with an input for external battery. It is used to supply the
controller in case of main voltage failure.
By using the HOT-KEY input/output port is possible to upload a new parameter map from (program the
controller) or save the actual parameter map to an external memory device (named HOTKEY
memory). Moreover, by using this port is possible to connect the device to a network line (ModBUS-
RTU compatible) such as a dIXEL monitoring units of X-WEB family. In this case, a special adapter
(XJ485-CX) has to be used.
3. CONTROLLING LOADS
3.1 COMPRESSOR
The regulation is performed according to
the temperature measured by the
thermostat probe with a positive
differential (HY) 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
Defrost is performed through a simple stop of the compressor. Parameter idF controls the interval
between defrost cycles, while its length is controlled by using MdF parameter.

8. DIGITAL INPUT
The free voltage digital input is programmable in 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 door alarm is enabled,
the display shows the message “dA” and the regulation restarts is rtr=Y. 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.
8.2 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 de-
activated.
8.3 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 de-
activated.
8.4 PRESSURE SWITCH (i1F = PAL)
If during the interval time set by did parameter the pressure switch reaches the nPS number of
activation, the “CA” pressure alarm message will be displayed and the compressor and the regulation
will be 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.
8.5 START DEFROST (i1F = dFr)
A defrost will start 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 for MdF safety time to
expire.
8.6 INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F = Htr)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
8.7 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.
8.8 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
9. TTL SERIAL LINE – FOR MONITORING SYSTEMS
It is possible to connect the instrument to a ModBUS-RTU compatible monitoring system (e.g.
X-WEB500/3000/300) by using the TTL serial line available on the HOTKEY connector. An external
adapter has to be used to connect the device to the network (e.g. a TTL/RS485 converter XJ485-CX).
10. INSTALLATION AND MOUNTING
Instrument XR30CX shall be mounted on vertical panel, in a 29x71
mm hole, and fixed using the special bracket supplied.
The temperature range allowed for correct operation is 060 °C.
Avoid places subject to strong vibrations, corrosive gases,
excessive dirt or humidity. The same recommendations apply to
probes. Let air circulate by the cooling holes.
11. ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up to
2.5mm2. 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.
11.1 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.
