∆U-3ph
You can use this parameter to specify a limit value for the voltage difference
in V (in relation to the secondary value of the voltage transformer) or in kV
(in relation to the primary value of the voltage transformer).
∆φ-3ph
You can use this parameter to specify a limit value for the phase angle differ-
ence.
∆U-3ph/∆φ-3ph delay time
You can use this parameter to set the delay time in order to delay the issuing
of the event message.
∆U-3ph/∆φ-3ph behavior
You can use this parameter to set the behavior of the device when the event
message is issued. You can select the following options:
Setting
Off
Auto blocking
Auto/manual blocking
Table 40: Behavior when an event message is issued
You can set 2 limit values for tap position monitoring:
▪ Pos<
▪ Pos>
You can set the following parameters for each limit value. A detailed descrip-
tion of the limit value concept and parameters can be found in the Limit val-
ues [►Section 8.10.7, Page 118] section.
▪ Behavior limit value
▪ Delay time (optional)
Operations counter
The device's operations counter is automatically increased with every tap-
change operation. You can use this parameter to set the number of tap-
change operations, such as for a comparison with the operations counter of
the motor-drive unit.
