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 On Point Function
fx Compressor 1 x x Close
fx Compressor 2 x x Close
fx Alarm relay x x NC
fx Main switch x x Close
fx P0 x x AKS 32R 1-6 bar
The connection survey from the controller and any extension
modules are uploaded from the paragraph "Module survey. E.g.

Mind the numbering.
The right-hand part of the
controller module may look like
a separate module. But it isn’t.
- Columns 1, 2, 3 and 5 are used for the programming.
- Columns 2 and 4 are used for the connection diagram.

Note
The safety relays should not be fitted onto a module
with override changeovers, as they can be put out of
operation by an incorrect setting.
