VISAIR  CABINETS    -  SERVICING 

 

Temperature 
Regulator 
XR40CX   

 

Model XR40CX is a microprocessor based 
controller.  
It is provided with 
three NTC probes. 
The first one for 
temperature 
control (air off), 

the second one, located on the evaporator coil, to 
control the defrost termination, the third one, connected 
to the HOT KEY terminals indicates the cabinet 
temperature (air on).  

The indicated set-point temperature will be lower than 
the air temperature inside the cabinet, because the 
refrigeration compressor is controlled in response to the 
exit air (air off) temperature from the evaporator cooling coils. 

After unplugging Pr4, from the HOT KEY terminals, one can programme the 
controller by means of a HOT KEY. 

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
