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.
Dixell Srl reserves the right to change the composition of its products, even without notice, ensuring the
same and unchanged functionality.
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.
2. GENERAL DESCRIPTION
Model XW220L, 38x185 mm format, is microprocessor based controller suitable for applications on normal
temperature refrigerating units. It is provided with two relay outputs to control compressor, and the lights
They are also provided with two NTC probe inputs, one for temperature control, one 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”.
An optional output for remote display “XW-REP” is available.
3. 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 FAST FREEZING
When defrost is not in progress, it can be activated the keypad by holding the okey 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, ofor about 3 seconds.
3.3 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).
Defrost is performed through a simple stop of the compressor. Parameter “IdF” controls the interval between
defrost cycles, while its length is controlled by parameter “MdF”.
4. KEYBOARD

6. DIGITAL INPUTS
The Wing series can support up to 2 free contact digital inputs. One is always configured as door switch, the
second is programmable in seven different configurations by the “I2F” parameter.
6.1 DOOR SWITCH INPUT
It signals the door status and the corresponding relay output status through the “odc” parameter:
no = normal;
Fan = normal;
CPr = Compressor OFF;
F_C = Compressor OFF.
Since the door is opened, after the delay time set through parameter “dOA”, the alarm output is enabled and the
display shows the message “dA”. The alarm stops as soon as the external digital input is disabled again. During
this time and then for the delay “dot” after closing the door, the high and low temperature alarms are disabled.
6.2 CONFIGURABLE INPUT - GENERIC ALARM (EAL)
As soon as the digital input is activated the unit will wait for “did” time delay before signalling the “EAL” alarm
message. The outputs status don’t change. The alarm stops just after the digital input is de-activated.

1592009000 XW220L GB r1.2 03.08.2015 XW220L 3/4
6.3 CONFIGURABLE INPUT - SERIOUS ALARM MODE (BAL)
When the digital input is activated, the unit will wait for “did” delay before signalling the “BAL” alarm message.
The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-activated.
6.4 CONFIGURABLE INPUT - PRESSURE SWITCH (PAL)
If during the interval time set by “did” parameter, the pressure switch has reached the number of activation of
the “nPS” parameter, the “PAL” pressure alarm message will be displayed. The compressor and the regulation
are stopped. When the digital input is ON the compressor is always OFF.
6.5 CONFIGURABLE INPUT - START DEFROST (DFR)
It executes a defrost if there are the right conditions. After the defrost is finished, the normal regulation will
restart only if the digital input is disabled otherwise the instrument will wait until the “Mdf” safety time is expired.
6.6 CONFIGURABLE INPUT - ENERGY SAVING (ES)
The Energy Saving function allows to change the set point value as the result of the SET+ HES (parmeter) sum.
This function is enabled until the digital input is activated.
6.7 CONFIGURABLE INPUT - REMOTE ON/OFF (ONF)
This function allows to switch ON and OFF the instrument.
6.8 DIGITAL INPUTS POLARITY
The digital inputs polarity depends on “I1P” and “I2P” parameters.
CL : the digital input is activated by closing the contact.
OP : the digital input is activated by opening the contact
7. INSTALLATION AND MOUNTING

8. ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5 mm2 for
the digital and analogue inputs. Relays and power supply have a Faston connection (6,3mm). Heat-resistant
cables have to be used. Before connecting cables make sure the power supply complies with the instrument’s
requirements. Separate the probe cables from the power supply cables, from the outputs and the power
connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads use a suitable
external relay.
N.B. Maximum current allowed for all the loads is 20A.
8.1 PROBE CONNECTIONS
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is
recommended to place the thermostat probe away from air streams to correctly measure the average room
temperature.
