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.
All different settings are categorize and placed in submenus.
The access comes through main menus.
MPC 46 and the new 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.
Service.
Make sure the appliance is switched off at the main socket or the cable is pulled out from the
wall before service is performed on electrical parts. It’s not sufficient to switch off the cabinet by
the
key as there will still be voltage 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 version 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).
Other program variants name:
F (freeze).
B (Counter).
V (Warm/hot/swallow cabinets)*.
P (Process cabinets).
E (Extreme low temperature).
