2. GENERAL WARNING
PLEASE READ BEFORE USING THIS MANUAL
1. This manual is part of the product and should be kept near the instrument for easy and quick
reference.
2. The instrument shall not be used for purposes different from those described hereunder. It
cannot be used as a safety device.
3. Check the application limits before proceeding.
4. Dixell Srl reserves the right to change the composition of its products, even without notice,
ensuring the same and unchanged functionality.
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 to prevent 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.
3. GENERAL DESCRIPTION
The XR03CX, in 3274x50mm short format, is microprocessor based controller suitable for applications on
normal temperature refrigerating units. It provides two relay output: one for compressor and the other one for
alarm signalling or as auxiliary output. It provides an NTC probe input and a digital input for alarm signalling,
for switching the auxiliary output or for start defrost. The instrument is fully configurable through special
parameters that can be easily programmed through the keyboard or the by HOTKEY.
The XR04CX, in 3274x50mm short format, is microprocessor based controller suitable for applications on
normal or low temperature refrigerating units. It provides two relay output: one for compressor and the other
one for defrost. It provides two NTC probe inputs, one for room temperature and other one to control defrost
termination. The instrument is fully configurable through special parameters that can be easily programmed
through the keyboard or the by HOTKEY.
4. REGULATION
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 Cy and Cn.
5. DEFROST
XR03CX
Defrost is performed through a simple stop of the compressor. Parameter id
