1. Go to Settings > Parameters > Grid > Voltage monitoring.
2. Select the desired parameter.
3. Set the desired parameter.
4. Press the Accept button to save the modified parameter.
You can set additional parameters for each limit value:
Mode
You can use this parameter to set which limit value you would like to use:
▪ Absolute: The device uses the absolute limit value in V.
▪ Relative: The device uses the relative limit value in %, relative to the de-
sired voltage value.
Behavior
You can use this parameter to set the behavior of the device if the measured
value is higher than the upper limit (> or >>) or lower than the lower limit (<
or <<). You can select the following options:
Setting Behavior
Off No reaction.
High-speed return For U</U<<: The device performs tap-change opera-
tions in the raise voltage direction (U+) until the mea-
sured voltage is back above the limit value.
For U>/U>>: The device performs tap-change opera-
tions in the lower voltage direction (U-) until the mea-
sured voltage is back below the limit value.
With high-speed return, the device ignores the set delay
time of automatic voltage regulation.
Auto blocking Automatic regulation is blocked.
You can continue to perform tap-change operations in
manual mode.
Auto/manual blocking Automatic regulation is blocked.
You cannot perform tap-change operations in manual
mode.
Auto blocking position+ The automatic control does not perform a tap-change
operation in the direction of a higher tap position (posi-
tion+).
You can still perform a tap-change operation in the di-
rection of a higher tap position (position+) in manual
mode.
