The introduction.
Since the introduction of our own standard controller I year 2001, the controller has gone through several software
updates. More program variants is developed, new functions is added to existing variants and others is been
improved.
There was a directly access to the menus on the front of our cabinet, which was a great help for the service men
and also for the workers in the factory here in Vojens.
All different settings are categorize and placed in submenus.
The access comes through main menus.
MPC 46 and the menus.
The menus are divided up in two main menus.
A menu for presentations of values in the display and settings for
alarms parameters, and another menu for technical, practical or
physical settings to a normal refrigerator or freezer.
In each main menu there exist smaller submenus.
These submenus are divided up in specific menu for kind of
cycles as defrosting or the settings for running the
evaporator fan.

765042364 Rev.000 4
Make sure the appliance is switched off at the socket before service is performed on electrical
parts. It is not sufficient to switch off the cabinet by the START/STOP key as there will still be
volta
g
e to some electrical parts of the cabinet..
Software version and program variant in start-up sequence
When the cabinet switches ON, the controller shows the software version and program variant.
The version number glows in 2 sec. followed by name on the program variant until the controller is finished with the
start-up sequence. The program variant is like the example here below.
In the example above software ver. 2.1 and program variant M2+ is presented.
Cabinets with compressor (HAV) is given by the symbol ” ”. The
symbol should look like a “+” which means including compressor.
Cabinets without compressor (FAV) is given by the symbol ” ”.
The “-“ symbol means “Compressor not included”.
Because program variants like K and M
is difficult to present in a 7-segment
display, the symbols below is used
instead:
H (Refrigerator).
n (Extended temperature range).
P (Process cabinets).
Other program variants name:
F (freeze).
B (Counter).
V (Varm/hot/swallow cabinets)*.
E (Extreme low temperature).

Error codes in the display during normal operation
- 0 - The door is open. The alarm system is activated, if the door is not closed within a certain time.
The user is reminded that the door is not properly closed.
F1 Cabinet sensor error. In the meantime the cabinet itself will maintain the set temperature by
the memory of the controller. Service assistance is required.
F2 Evaporator sensor error.
The cabinet will keep running until the error has been mended.
Service assistance is required.
F3/F4 Condenser sensor error. The cabinet will keep running, until the error has been mended.
Service assistance is required.
Applies only to cabinets with built-in compressor.
F5 Error on the sensor for temperature controlled chilling. It has no influence on other
programmes, but it should be replaced. Service assistance is required.
F7 Indicates that the condenser temperature is too high. The cause might be a clogged
condenser, or too high ambient temperature.
If the condenser or air filter needs cleaning, the cabinet must be disconnected at the mains
power. Cleaning of the condenser is done with a brush or a vacuum cleaner.
The air filter can be removed and cleaned in a dishwasher at max. 50C.
If the ambient temperature is too high, the placement of the cabinet might be wrong, and an
alternative place should be found. Ventilation might help.
If this does not help, request service assistance.
