Setting the lower speed limit
1. Remove the plug from the electrical input.
2. Loosen the counter nuts against each other by means of two combination spanners SW 10.
3. Connect an electrical voltmeter in the range up to 300 Volt AC to the AC Control Box output.
4. Ensure there is no electrical load.
5. Start generator.
6. By turning the servo meter spindle downwards by hand until the voltmeter shows a value of 225 volts (110V).
7. Tighten both nuts tightly against each other.
8. Once again check whether the lower generator voltage of the generator without load is limited to 225 volts (110
volts).
Setting the upper speed limit:
1. Continue as above and tighten the counter nuts at a voltage of max. 260 volts (130 volts).
2. Once again check whether the upper generator voltage without load is limited to 260 V (130 V)
