Mains voltage unbalance detection
The formula for mains voltage unbalance is:
(Most deviating line-to-line voltage - average voltage)*100/average voltage (nominal value in %)
Phase sequence error
Prior to closing a breaker, the unit checks that the phase sequence is correct, depending on the
chosen phase direction in parameter 2280: “phase rotation”. If it is incorrect (reversed), an alarm
will be issued and the breaker in question (generator or option B3 mains breaker) will not be
closed and the breaker’s LED will flash red.
Utility software input configuration
It is possible to configure the inputs indicated in the table. The unit has a number of passive
binary inputs (input terminals 10 to 15).
