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 p 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 (p) in manual
mode.
