Alarm function
For alarm function AF1 to AF6, the resulting limit value depends on the setpoint value – the
entered limit value is added to the setpoint value or subtracted from the setpoint value. Alarm
functions AF7 and AF8 work with a fixed limit value that corresponds to the entered limit value.

Hysteresis function
The designations "Asymmetric left" and "Asymmetric right" typically relate to alarm functions
AF3/AF4 and AF7/AF8. The designation is not conclusive for alarm functions AF1/AF2 and
AF5/AF6.

Start-up alarm suppression
An active start-up alarm suppression means:
•
After power on, the output signal 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 output signal remains inac-
tive.
• 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 output signal remains inactive
until the actual value returns to the alarm range.
Signal at O-o-R Output signal if measurement range is exceeded or not met
OFF Output signal inactive
ON Output signal active
