Situation
• Mains becomes normal when all of the parameters below are inside their working
ranges:
◦ »Overvoltage«
◦ »Undervoltage«
◦ »Overfrequency«
◦ »Underfrequency«
◦ »Mains voltage asymmetry«
◦ »Mains phase rotation fail«
The AUTO Stop procedure is going through sub procedures with own timers.
If the mains becomes abnormal during the process, remaining with generator load has
priority.
The remaining time of each of the timers initiated displays.
When started via “Remote Stop (off Load)” input, the starting procedure is the same as
shown below but the generator close relay is deactivated.
