2G 1,6D/Y
5.5.4.1 Relay card
Scope of suply:
5.5.4.1.1 Operating principle
control electronics.
It has four relays for signalling system states and positions digitally to a higher-level control or for
connecting relays 1 and 2 to local power consumers (pumps, butterfly valves, etc.).
Two buttons are provided for programming two positions. If a position is overtravelled, the
corresponding travel-dependent relay is switched.
The switching states of the travel-dependent relays are indicated by two LEDs.
If a position is programmed for a switched Force switch, e.g. in a final position, the corresponding
relay is only switched if this Force switch is actuated, regardless of the position. This can be the
case if a blockage occurs, for instance. A blockage additionally results in a "Failure" signal because
the desired position cannot be reached.

Failure
Red LED on the motherboard
NOTE !
The Failure relay is
switched (high) in normal operation
.
If a fault occurs, the relay drops out to enable a mains voltage or electronics failure to
be signalled as well.
The relays are not switched if the handwheel is adjusted or an initialization run is
started.
