Dixell Digital Ccontroller XR03CX–XR04CX With Sensor For Coldroom And Freezer Temperature Control

GENERAL DESCRIPTION -DIGITAL CONTROLLER XR03CX, XR04CX

The XR03CX, in 32×74x50mm 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 32×74x50mm 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.

DEFROST

Two defrost modes are available through the “td” parameter:

• td=EL → defrost through electrical heater (compressor OFF)

• td=in → hot gas defrost (compressor ON).

Other parameters are used to control the interval between defrost cycles (id) ), its maximum length (Md) and two defrost modes: timed or controlled by the evaporator’s probe. At the end of defrost dripping time is started, its length is set in the dt parameter. With dt=0 the dripping time is disabled

FANS

With FC parameter it can be selected the fans functioning:

• FC=cn → will switch ON and OFF with the compressor and not run during defrost

• FC=on → fans will run even if the compressor is off, and not run during defrost

After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fd” parameter.

• FC=cy → fans will switch ON and OFF with the compressor and run during defrost

• FC=oY → fans will run continuously also during defrost.

An additional parameter “FS” 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 “FS”

FANS AND DIGITAL INPUT

When the digital input is configured as door switch iF=do, fans and compressor status depends on the dC parameter value:

• dC=no → normal regulation;

• dC=Fn → fans OFF;

• dC=cP → compressor OFF;

• dC=Fc → compressor and fans OFF.

When rd=y, the regulation restart with door open alarm.
