P.0 Mains Contactor control (KM).
If the Mains Failure persists for more than [P.0]
(seconds or minutes), the Mains contactor will open and the [P.1] timer will start to
count. The Mains contactor will close only after the [P.2] timing.

P.1 Mains Failure time.
After the [P.0] timing (see above), the engine will start if the
Mains Failure persists for the [P.1] time.

P.2 Mains Restore time.
The Be42 transfers the Load to the Mains once the MAINS is
stable for at least [P.2] (seconds, minutes or hours) . During [P.2] , the engine will
