Stage Ugenerated for alarm purposes, the Start/Alarm indicator LED is lit and the fault is
indicated as an alarm instead of a trip.
When stage U* Start signal of stage is not generated
* Trip signal of stage is generated, but it is indicated as an alarm
* Stage cannot be used for triggering CBFP
* Number of starts is increased instead of number of trips
When the conventional protection mode is selected and the voltages fall below the
set start value of the high-set stage, U<<, the stage generates a start signal after a ~
50 ms’ start time. When the set operate time at definite-time characteristic or the
calculated operate time at IDMT characteristic elapses, the stage generates a trip
signal. The stage is reset in 70 ms after the phase-to-phase voltages have exceeded
the set start value of the stage.
The undervoltage stages have a settable drop-off/pick-up ratio, which is adjustable
between 1.01...1.05, the default being 1.03.
