Bypass Input Phase Loss
Level
The bypass measures the current unbalance between phases to detect input phase loss.
Sets the current level between phases in Bypass Mode.
Usually it is not necessary to change this parameter.

Bypass Input Phase Loss
Delay
Sets the trip time for an input phase loss condition in Bypass Mode.
Note:
When you set this parameter to 0.0, it will disable bypass phase loss detection.
