Determine The Connection Points - Danfoss AK-CC 750 series Manual

Determine the connection points

All connections must be programmed with module and point, so
in principle it does not matter where the connections are made, as
long as it takes place on a correct type of input or output.
• The controller is the first module, the next one is 2, etc.
• A point is the two or three terminals belonging to an input or
output (e.g. two terminals for a sensor and three terminals for a
relay).
The preparation of the connection diagram and the subsequent
programming (configuration) should take place at the present
time. It is most easily accomplished by filling in the connection
survey for the relevant modules.
Principle:
Name On module
fx Compressor 1
fx Compressor 2
fx Alarm relay
fx Main switch
fx P0
The connection survey from the controller and any extension
modules are uploaded from the paragraph "Module survey. E.g.

- Columns 1, 2, 3 and 5 are used for the programming.
- Columns 2 and 4 are used for the connection diagram.
