B.3.1 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.
1. Counter nut
2. Adjustment screw for upper setting
3. Speed Adjustment Lever
This setting should not be changed
otherwise the guaranty will expire.
