NOTE
When Start Command is available, it is possible to avoid the switching off and on
of the generator, resetting the following protections by commutating OFF and ON
the start command switch:
- Overload, - Over temperature,
- Output under voltage (not severe), - Output under voltage (severe).
In case of more than a fault condition at the same time, the priority of
signalization will be as per the following:
1.
BUS Overvoltage
2.
Overload condition
3.
Over temperature.
