Function monitoring
You can use this parameter to activate function monitoring. You can select
the following options:
Setting Behavior
Off Function monitoring is deactivated.
Only Auto Function monitoring is only active in AVR AUTO oper-
ating mode.
Auto and Manual Function monitoring is active in AVR AUTO and AVR
MANUAL operating mode
Table50: Activate function monitoring
Hysteresis limit value
You can use this parameter to set the hysteresis. You can use this to avoid
the unnecessary generation of messages if the measured value fluctuates
around a threshold value.
Delay time limit value
You can use this parameter to set the delay time in order to delay the issuing
of the event message.

7.8.7 Phase symmetry monitoring
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module, you can set the maximum permitted differences for voltage and
phase angle between the 3 phases. The difference is determined from the
highest and lowest measured value of the 3 phases.
The following parameters are available for configuring phase difference
monitoring:
▪ ∆U-3ph
▪ ∆U-3ph behavior
▪ ∆U-3ph delay
▪ ∆φ-3ph
▪ ∆φ-3ph behavior
▪ ∆φ-3ph delay
