B.2.2 Automatic Voltage Monitoring and Auto-Shut Down
If air conditioning units (compressors) or other such valuable equipment is installed on-board, it is
recommend that an automatic voltage monitoring unit be installed to protect this equipment from
possible sharp voltage drops. The voltage monitoring system shuts down the entire system (and
therefore all users) by means of a circuit breaker relay as soon as the voltage falls below a set
value (the monitor will also shut down the on-board grid automatically when the generator is stop-
ped). Such a relay with contactor can be obtained from the installator or as a complete unit from
your Fischer Panda dealer.
B.3 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.
1. Servo motor
2. Trapezoidal Thread Spindle
3. Adjusting nuts for max. speed
4. Spindle nut with speed adjusting lever
5. Adjusting nuts for the lower setting

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 discon-
nected to avoid an accidentally activation of the booster capacitors.
