The connection assignments for the individual relays in the zero-current state can be found
in the routing assignments "Motherboard pin assignments". The relays are preset at delivery.
Press the fifth softkey ("...continue"), to access the next function screen, thus branching to
further relays.

Signaling contact*
When there's a signal,
the relay conducts
current for a short time
e.g. in the case of
AUTOCAL:
actuation of a second
device
Autocal check
