GENERATOR PROGRAMMING
GENERATOR UNDERVOLTAGE.
The protection device is activated when the generator voltage steadily stays higher than the
programmed value for 10 seconds. The preset threshold is 335V with intervention delay of 3 seconds.
GENERATOR VOLTAGE PRESENT.
The generator contactor closes when the voltage steadily
remains above the programmed threshold for the entire generator connection to power user delay time.
GENERATOR UNDERFREQUENCY.
By factory default, the protection device is switched off. To activate it, you must program an intervention frequency
different from 0 Hz. The protection device is activated when the generator frequency steadily stays higher than the
programmed value for 10 seconds.
GENERATOR OVERFREQUENCY.
The factory set threshold is 60 Hz, suitable for 50 Hz systems. In the event of
OVERFREQUENCY, the engine is stopped. The stop is not programmable.
GENERATOR OVERVOLTAGE.
It is factory programmed to stop.
