Limit comparator with start-up suppression :
As before, but the alarm contact is first closed after
initial start-up and opens, if the alarm value has
reached once the good range.
Every alarm contact acts as a common alarm for all
zones. All alarm limit values in the different zones
programmed as A1 switch relay A1 (pins 4 and 5), all
values programmed as A2 switch relay A2 (pins 2 and 3
of the alarm connector).
The previsously described alarm configuration for A1 and
A2 is valid for all active zones.
The different alarm limit values can be set individually for
every zone in the operation level - control parameters
„Alarm A1“ and „Alarm A2“ (see chapter 6.3).
