We set up the controller's digital outputs by keying in which module
and point on this module each one of these has been connected to.
We furthermore select for each output whether the load is to be active
when the output is in pos. ON or OFF.
Attention! Relay outputs must not be inverted at unloader valves. The
controller inverts the function itself.
There will be no voltage at the bypass valves when the compressor is not
in operation. Power is connected immediately before the compressor is
started.

We set up the controller's digital input functions by keying in which
module and point on this module each one of these has been connected
to.
We furthermore select for each output whether the function is to be ac-
tive when the output is in pos. Closed or Open.
Open has been selected here for all the safety circuits. This means that
the controller will receive signal under normal operation and register it
as a fault if the signal is interrupted.
