7.1. Controller Module (CM)
The controller module, consisting of two PCBs, is fitted with
relays
for indica-
tion of maintenance mode (make contact), single mode (make contact) as well as
system failure (break contact). The relays are only provided for signals of up to
30V DC, 0.1A.
The
rotary switch
allows setting of the various functions for servic-ing. (see
3.4. Maintenance Mode)
By means of the input for external buzzer reset, all buzzer relays can be reset via
an external key button.
In case no emergency power is supplied (with a 24V signal), a bridge connection
between the 24V inputs is to be made.
