This setpoints determines the delay for mains under- (defined by
) protections.

:
Although the resolution of this setpoint is 0.01s, in fact the adjusted delay is
rounded to the next higher multiple of the period of the generator voltage.
The period is either 0.02s for 50Hz systems or 0.0166s for 60Hz systems.
E.g. if the delay is set to 0.03s at 50Hz system the real delay will be 0.04s.
