D.1.1Generator Voltage Fluctuations and Monitoring
ATTENTION! Before working (installation) on the System read the section Safety Instruc-
tions in this Manual.
During periods of high electric loading, the voltage may drop to 190V/50Hz (or 95V/60Hz) or even
lower. Such voltage drops can potentially cause damage to certain electrical devices such as
electric motors, compressors and electronic equipment. In order to ensure that sufficient voltage
is available and to avoid the risk of damage to sensitive electrical devices, the supply voltage
should be monitored with the voltmeter, which is mounted at the operation unit.
The voltmeter must be respectively checked if additional load is switched on. As long as the
voltage remains below the critical level the sensitive devices must be switched off during this
period.
Overvoltage can be caused by the generator under certain circumstances. This occurs, especi-
ally if the speed of the motor changes (increases in speed). Adjustment to the normal motor
speed (rpm) should only be done with the use of a rev counter and/or a voltmeter.
A voltage regulated circuit breaker is installed in the electrical system in order to avoid damage, if
sensitive or valuable equipment is used. (voltage control with circuit breaker).
D.1.2Automatic Voltage Monitoring and Auto-Shut Down
If air conditioning units (compressors) or other such valuable equipment are installed on-board,
an automatic voltage monitoring unit should be installed to protect this equipment from possible
sharp voltage drops. The voltage monitoring system shuts down the entire system (and therefore
all users) through a circuit breaker relay as soon as the voltage falls below a set value (the moni-
tor will also shut down the on board grid automatically when the generator is stopped). The moni-
toring system also switches the grid back on once the required voltage level is again reached.
This ensures no damage is caused to the load and fittings through undervoltage. Such a voltage
relay can be obtained from wholesale dealers or as a complete unit from PANDA dealers.
The circuit is always automatically cut off if the generator is stopped.
D.1.3Adjusting Instructions for the Spindle of the actuator
There are two independent regulation devices for the rev range of the generator. Limited upward
and downward:
a) With the regulation nuts at the spindle of the actuator left and right of the spindle nut.
b) With an adjusting screw directly at the base of the rev regulator lever. (only up)
After all work at the components of the rev regulation is done the adjustment of the limitation must
be checked.
