Potential Free Signal Output
10.1
Base Relay and Signal Relay PCB
The contact load is 250V/5A.
10.1.1
Base Relay and Collective Fault
The base relay (on the PCB) delivers a potentialfree two-way contact
(load: 250V/8A) to terminals 28, 29 and 30.
It is triggered when a specified operational condition is present. The
preset operational condition is “Collective Fault.”
It is possible, but not advisable, to assign another operational condition
to the base relay / relay circuit (also see Summary Table of Parame-
ters, Parameter E5).
If the steam generator C01 or C02 is equipped with the "option 230V
supply fan for C01 and C02" or "option 230V exhaust fan for C01 and
C02", the switching message „Collective Fault” is not available.
Humidification:
The message

can be directly accessed from the main
contactor as indicated in the wiring diagram.

Signal Relay PCB and Steam Bath Operation*
The signal relay PCB is optinal attached to the main PCB of the DS-
Comfort / Plus Control or the Basic-DS. The signal relay PCB provides
four additional signal relays. Each relay is designed to control a speci-
fied steam bath component. Below are the factory settings for the relay
switching functions:
