Function
For the AF1 to AF6 alarm functions, the final limit value depends on the setpoint value – the entered limit value is
added to or subtracted from the setpoint value. The AF7 and AF8 alarm functions work with a fixed limit value which
corresponds to the limit value entered.

chapter 9.12.1 „Alarm functions and switching behavior"
Startup alarm suppression
Function of the startup alarm suppression:
•
After power on, the alarm signals for the limit value monitoring function remains inactive, even if the actual value is
in the alarm range.
•
If the limit value or setpoint value is changed so that the actual value is then within the alarm range, while the actual
value is outside of the alarm range, the alarm signal remains inactive.
•
The limit value monitoring only starts to operate according to its alarm function again once the actual value has left
the alarm range. This means that the alarm signal remains inactive until the actual val ue returns to the alarm range.
Behaviour after power on
The output signal status is not saved via power off. Limit value monitoring starts after completion of ini tialization ac-
cording to its configuration.
