Setting Behavior
Auto blocking ▪ The Reversal of power flow event is issued.
▪ If Z compensation is activated, this function is deacti-
vated.
▪ Automatic regulation is blocked.
Auto/manual blocking ▪ The Reversal of power flow event is issued.
▪ If Z compensation is activated, this function is deacti-
vated.
▪ Automatic regulation is blocked.
▪ You cannot perform tap-change operations in manual
mode.
Target tap position ▪ The Reversal of power flow event is issued.
▪ If Z compensation is activated, this function is deacti-
vated.
▪ The device triggers a tap-change operation to the tap
position you defined in the "Target tap position" pa-
rameter.
▪ The device blocks further tap-change operations.
▪ The target-tap-position operation is ignored if there is
no tap-position capture. Automatic regulation is
blocked.

8.10.5 Bandwidth monitoring
The following limit values are monitored via bandwidth monitoring. The set
bandwidth [
► Section 8.4.2, Page 75] is used for this purpose.
▪ Upper bandwidth
▪ Lower bandwidth
You can set the following parameters for each limit value:
▪ Hysteresis limit value: Specification as a percentage relative to the de-
sired voltage value.
▪ Delay time limit value
Behavior If the measured value is higher than the upper limit or lower than the lower
limit, the device triggers the
Upper bandwidth limit value / Lower bandwidth
limit value message.
The "Function monitoring" function is used to detect long periods when val-
ues exceed or fall below the bandwidth. Long periods when values exceed
or fall below the bandwidth indicate a problem with the device function be-
cause the device is not able to correct the control deviation.
Behavior If the value falls below or exceeds the set bandwidth [ ► Section 8.4.2, Page
75], the Function monitoring event is displayed after the set delay time for
function monitoring has elapsed. The event is automatically acknowledged
as soon as the measured value returns to within the set bandwidth.
