  • Page 92 CGC 400 DRH 4189340786 UK Additional functions In order to prevent some battery low voltage alarm to occur during the voltage decrease curve, when unplug- ging the unit, the range of timer for this alarm will be changed. It will not be possible to set a timer below 10 seconds for alarm.

    CGC 400 DRH 4189340786 UK Protections 8.2 Voltage-dependent (restraint) overcurrent This protection is used when the generator must be tripped due to a fault situation that creates a reduced generator voltage, e.g. a voltage collapse. During the voltage collapse, the generator can only produce part of its usual rating.
