7. Connection and configuration of the modules
7.1. Controller module (CM)
The CM, consisting of two PCBs, is fitted with relays for indication of service
mode (make contact), single mode (make contact) as well as system failure
(break contact). The relays are only provided for signals of up to 30 V DC, 0.1
A.
The rotary switch allows setting of the various functions for servicing (see
chapter 3.4).
At the External Reset input all relevant relays and latching alarms can be reset
with an external key connected.
In case no emergency power is supplied (24 V), a bridge connection between the
24 V inputs has to be made.
