1. 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.p.A.
(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 XW40LS, 38x185 mm format, is microprocessor based controller suitable for applications on
medium or normal temperature refrigerating units. It is provided with 3 relay outputs to control
compressor , light and fan.
It is also provided with 1 NTC or PTC probe inputs for temperature control.
An output allows the user to programme the parameter list with the “Hot Key”.
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”.

6. INSTALLATION AND MOUNTING
Instruments XW40LS shall be mounted on vertical panel, in a 150x31 mm hole, and fixed using two
screws ∅3 x 2mm. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RG-
LX). The temperature range allowed for correct operation is 0 - 60 °C. Avoid places subject to strong
vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes.
Let the air circulate by the cooling holes.

7. ELECTRICAL CONNECTIONS
The instruments are provided with Faston (2,8mm) to connect the 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.
7.1 PROBE CONNECTIONS
The probe 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.
8. USE OF THE PROGRAMMING “HOT KEY “
The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
“Hot Key” and vice-versa.
8.1 DOWNLOAD (FROM THE “HOT KEY” TO THE INSTRUMENT)
1. Turn OFF the instrument by means of the ON/OFF key, remove the TTL serial cable if present,
insert the “Hot Key” and then turn the Wing ON.

2. Automatically the parameter list of the “Hot Key” is downloaded into the Wing memory, the
“doL” message is blinking. After 10 seconds the instrument will restart working with the new
parameters.
3. Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
“End “ for right programming. The instrument starts regularly with the new programming.
“Err” for failed programming. In this case turn the unit off and then on if you want to restart the
download again or remove the “Hot key” to abort the operation.
8.2 UPLOAD (FROM THE INSTRUMENT TO THE “HOT KEY”)
1. Turn OFF the instrument by means of the ON/OFF key and remove the TTL serial cable if
present; then turn it ON again.
2. When the Wing unit is ON, insert the “Hot key” and push okey; the "uPL" message
appears.
3. Push “SET” key to start the UPLOAD; the “uPL” message is blinking.
4. Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
“end “ for right programming.
“err” for failed programming. In this case push “SET” key if you want to restart the programming again
or remove the not programmed “Hot key”.
9. ALARM SIGNALS
Message Cause Outputs
“P1” Thermostat probe failure
A
larm output ON; Compressor output according to
parameters “COn” and “COF”
“HA” Maximum temperature alarm Alarm output ON; Other outputs unchanged
“LA” Minimum temperature alarm Alarm output ON; Other outputs unchanged
“EE” Data or memory failure Alarm output ON; Other outputs unchanged
The alarm message is displayed until the alarm condition is recovery.
All the alarm messages are showed alternating with the room temperature except for the “P1” which is
flashing. To reset the “EE” alarm and restart the normal functioning press any key, the “rSt” message is
displayed for about 3s.
9.1 SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key.
9.2 “EE” ALARM
The dIXEL instruments are provided with an internal check for the data integrity. Alarm “EE” flashes
when a failure in the memory data occurs. In such cases the alarm output is enabled.
9.3 ALARM RECOVERY
Probe alarm: “P1” (probe1 faulty), automatically stops 10s after the probe restarts normal operation.
Check connections before replacing the probe.
Temperature alarms “HA” and “LA” automatically stop as soon as the thermostat temperature returns
to normal values or when the defrost starts.
