8.4.3 Generator Voltage Fluctuations and Monitoring
Notice!: Before working (installation) on the System read the
section Safety Instructions in this Manual.
During periods of high electric loading, the voltage may drop to 190 V/50 Hz (or 95 V/60 Hz) 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.
Over voltage can be caused by the generator under certain circumstances. This occurs, especially 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).
8.4.4 Automatic 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 monitor will also shut down the on board grid automatically when the
generator is stopped). The monitoring 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 under voltage. 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.
8.5 Low Generator-Output Voltage
If the produced alternating voltage is too low, switch the consumers off, in order to relieve the generator. Mostly the
problem already solved. If the output voltage is still too low, even if all consumers are switched off, the generator
runs without load, you can assume one or more condensers are defective.
8.5.1 Discharge the capacitors
ATTENTION! Never work at the electrical cabinet, when the generator is
running! Do not contact the capacitor. Before working on the
system read the section “Safety first!” on Page 12.
