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.
See chapter 7.3.8 "Limit value monitoring", Page 54
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.
