Scope Of This Service Manual; Introduction To This Manual - Gram COMPACT 220 Service Manual

Scope of this service manual

This service manual is made in order to aid service technicians when servicing and troubleshooting
on the Gram Compact product range, and in particular related to the electrical controller (GCC).
The service manual is not intended to be handed to end-users, since unintended changes of
settings potentially can cause situations where the temperature inside the cabinet cannot be kept as
intended, (high foodstuff temperatures can occur if wrong adjustments are made).
Another side effect of making unintended changes of the controller settings, is potentially causing
damage to the refrigeration system.
Changing service level parameter settings to differ from the factory default, will void the
warranty!
This service manual does explain how to access the different additional controller levels related to
service. These levels are:

Entering / adjusting factory default parameter settings (adjustable if necessary)

Entering and using the I/O test area

How to boot the correct software on a spare part controller

How to change the controller and what to take care of while doing so
Furthermore, this manual does explain:

The layout of the controller and the different connections including the specifications of these.

EC declaration of conformity

Wiring diagrams for:
o K – Models (Refrigerators with solid door)
o F – Models (Freezers with solid door)
o KG/FG – Models (Refrigerators and freezers with glass door)
