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
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 o 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, o for 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
To display and modify target set point; in programming mode it selects a parameter or
confirm an operation.
By holding it pressed for 3s when max or min temperature is displayed it will be erased.
To see the max. stored temperature; in programming mode it browses the parameter
codes or increases the displayed value. By holding it pressed for 3s the fast freezing cycle
is started.
To see the min stored temperature; in programming mode it browses the parameter codes
or decreases the displayed value.
By holding it pressed for 3s the defrost is started.

4.2 HOW TO SEE THE MIN TEMPERATURE
1.
Press and release the n key.
2.
The "Lo" message will be displayed followed by the minimum temperature recorded.
3.
By pressing the n key or waiting for 5s the normal display will be restored.
4.3 HOW TO SEE THE MAX TEMPERATURE
1.
Press and release the o key.
2.
The "Hi" message will be displayed followed by the maximum temperature recorded.
3.
By pressing the o key or waiting for 5s the normal display will be restored.
4.4 HOW TO RESET THE MAX AND MIN TEMPERATURE RECORDED
To reset the stored temperature, when max or min temperature is displayed :
1.
Press SET key until "rST" label starts blinking.
N.B. After the installation RESET the temperature stored .
4.5 HOW TO SEE AND MODIFY THE SET POINT
1.
Push and immediately release the SET key: the display will show the Set point value;
2.
The SET LED start blinking;
To change the Set value push the o or n arrows within 10s.
3.
4.
To memorise the new set point value push the SET key again or wait 10s.
4.6 TO START A MANUAL DEFROST
1.
Push the DEF key for more than 2 seconds and a manual defrost will start.
4.7 TO ENTER IN PARAMETERS LIST "PR1"
To enter the parameter list "Pr1" (user accessible parameters) operate as follows:
+
4.8 TO ENTER IN PARAMETERS LIST "PR2"
To access parameters in "Pr2":
1.
Enter the "Pr1" level.
2.
Select "Pr2" parameter and press the "SET" key.
3.
The "PAS" flashing message is displayed, shortly followed by "0 - -" with a flashing zero.
4.
Use o or n to input the security code in the flashing digit; confirm the figure by pressing "SET".
The security code is "321".
5.
If the security code is correct the access to "Pr2" is enabled by pressing "SET" on the last digit.
Another possibility is the following: after switching ON the instrument the user can push Set and DOWN
keys within 30 seconds.
NOTE: each parameter in "Pr2" can be removed or put into "Pr1" (user level) by pressing "SET" + n.
When a parameter is present in "Pr1" LED
