GENERAL WARNING

1.1

PLEASE READ BEFORE USING THIS MANUAL

•

This manual is part of the product and should be kept near the instrument for easy and quick

reference.

•

The instrument shall not be used for purposes different from those described hereunder. It cannot be

used as a safety device.

•

Check the application limits before proceeding.

1.2

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.

GENERAL DESCRIPTION

Model XW272K is microprocessor based controller suitable for applications on medium or low temperature

refrigerating units. It must be connected by means of a two-wire cable (∅ 1mm) at a distance of up to 30

meters to the keyboard T620. It is provided with six relay outputs to control two compressors, defrost — which

can be either electrical or hot gas — the evaporator fans, the lights and the alarm. It is also provided with

three NTC probe inputs, one for temperature control, one to control the defrost end temperature of the

evaporator and the third, optional, for the display. There are two digital inputs (free contact) for the door

switch and configurable by parameter.

The standard TTL output allows the user to connect, by means of a TTL/RS485 external module, a

ModBUS-RTU compatible monitoring system and to programme the parameter list with the «Hot Key». A

4÷20 mA output to control evaporator or condenser fans and the direct serial output RS485 are available as

options.

CONTROLLING LOADS

3.1

THE COMPRESSOR

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

«COn» and «COF».

3.2

SECOND COMPRESSOR

The second compressor is switched ON after a delay (AC1) of the first compressor activation. Compressors

can be switched ON always with the same sequence or in an alternate way.

CCO = Se : The first compressor is always switched on before the second one.

CCO = Al : The compressors are switched on in an alternate way.

3.3

FAST FREEZING

When defrost is not in progress, it can be activated the keypad by holding the è key pressed for about 3

seconds. The compressor operates in continuous mode for the time set through the «CCt» parameter. The

cycle can be terminated before the end of the set time using the same activation key, è for about 3

seconds.

3.4

DEFROST

Three defrost modes are available through the «tdF» parameter: defrost with electrical heater, hot gas or

thermostatic defrost. The defrost interval is control by means of parameter «EdF»: (EdF=in) the defrost is

made every «IdF» time, (EdF=Sd) the interval «IdF» is calculate through Smart Defrost algorithm (only when

the compressor is ON and the evaporator temperature is bigger than «SdF» parameter).

At the end of defrost the drip time is controlled through the «Fdt» parameter.

3.5

CONTROL OF EVAPORATOR FANS

The fan control mode is selected by means of the «FnC» parameter:

C-n = running with the compressor, OFF during the defrost;

C-y = running with the compressor, ON during the defrost;

O-n = continuous mode, OFF during the defrost;

O-y = continuous mode, ON during the defrost;

It is also provided with three NTC probe inputs, one for temperature control, one to control the defrost end

temperature of the evaporator and the third, optional, for the display. There are two digital inputs (free

contact) for the door switch and configurable by parameter.

The standard TTL output allows the user to connect, by means of a TTL/RS485 external module, a
