5.3.2 Supply / Exhaust damper
Air and exhaust air dampers are enabled and preconfigured in configuration 1, con-
figuration 2 and configuration I/Os.
Per settings outside and exhaust air damper open at plant start and close at plant
stop. Damper opening times can be defined separately. A common default period
can be set if no damper feedback exists. The damper command can still be kept at
pending for a feedback alarm.
Only the output for the outside air damper is enabled if two dampers are enabled
as combined. This is also true for triggering feedback alarms for the exhaust air
damper, if a separate feedback per damper is enabled.
Outside damper is forced by the supply fan. Exhaust damper is forced by the
exhaust fan. If combined damper is selected, then the output for ouside damper is
forced by both supply fan or exhaust fan. Take care if for example Firemode
RunExh is used.

fault: 5 s).
Determines, in the event of a feedback fault,
whether a damper command is still pending or
whether to switch off the command.
Defines the period after an open command without
feedback before a feedback alarm is triggered. Jit-
ter time is enabled exclusively if the feedback is
pending after this period.
