7.7 Setting the speed governor of the actuator
The speed of the generator is determined by two independent settings; an upper and lower speed governor:
• By means of the adjusting nuts on the spindle of the servomotor right and left from the spindle nut (Setting of the
normal speed limit).
• By means of an adjusting screw that is located on the base of the speed control lever. (Setting of the maximum
upper speed).
After working on the components of the actuator, the speed must be checked.

During any operation at the generator all consumers have to be switched off to avoid damages at the equipments.
Also the solid state relay, which is installed in the AC control box must be disconnected to avoid an accidentally
activation of the booster capacitors.
7.7.1 Setting the maximum upper speed setting
1. Remove the plug from the electrical input for the actuator.
2. Loosen the counter nuts of the speed governor screws with a combination wrench SW 10.
3. Connect a voltmeter with a range up to 300 Volts AC to the AC Output of the AC Control Box.
4. Ensure that no electrical load has been set.
5. Start generator.
6. Raise the speed of the generator by turning the spindle of the servomotor until the voltmeter reaches 260 Volts
(130 Volts).
7. Turn the governor screw firmly against the stop setting of the speed adjustment lever.
8. Secure the governing screw by means of the counter nut.
9. Once again check whether the generator voltage is governed to 260 Volts (130 Volts).
The upper speed settings serve as an additional safety factor. The value for the maximum voltage is therefore
approx 5 volts above the normal running limit.
