Function block faults

12.1

Function block overview

The task of function block "Faults" is to collect and evaluate all fault status messages,
and to trigger appropriate actions to prevent damage to the building and plant.
The function block is always active for internal fault status messages. In the extra con-
figuration – in addition to the fault inputs of the boiler sequence manager, the fault in-
puts of boilers 1 through 6 and pumps – up to 4 inputs can be activated as fault inputs
for external signal sources.
It is also possible to monitor inputs that have already been configured (e.g. the main
flow sensor).
To signal faults, 2 relays can be configured as fault outputs.

In the extra configuration, a maximum of 4 universal fault inputs and 2 fault relays can
be configured.
The inputs can be configured to free inputs, or analog inputs that are already used can
be monitored for limit value crossings.
