XR40CX
Model XR40CX is a microprocessor based
controller.
It has three NTC probe inputs, the first one
for temperature control, the second one,
located on the evaporator, to control the
defrost termination temperature, the third
one, located on the condenser discharge
pipe, to signal a condenser temperature alarm.
Since the temperature control probe is located on the return air side of the coil,
(Air On), the measured temperature will be higher than the average air
temperature inside the cabinet.
The HOT KEY output allows one to programme 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.
XR40CX
Compressor
Control
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 a fault in the thermostat probe the start and stop of the compressor
are timed through parameters
COn
and
COF
.
XR40CX
Defrost Control
Parameters are used to control the interval between defrost cycles (IdF), its
maximum length (MdF) and two defrost modes: timed or controlled by the
evaporator’s probe (P2P).
In this cabinet, the start of the defrost cycle is timed, but the cycle will be
terminated as soon as the defrost probe reaches the pre-determined
temperature.
At the end of defrost dripping time is started, its length is set in the FSt
parameter. With FSt =0 the dripping time is disabled
