7.4.1 Monitoring the Generator Voltage
Notice!:
see “Safety instructions - Safety first!” on Page 14.
Follow the general safety instruction at the front of this manual.
The voltage range of the power stations normally lies between 100V and 130V in the 60Hz version. In some coun-
tries even substantially larger tension deviations are being called "normally". The PANDA generators are aligned
that they keep these default values during normal load.
With high load or overload it can occur that the voltage drops on 95V in the 60Hz version and partly still more deeply.
That can become critical for certain devices (e.g. for electric motors, cooling compressors and possibly for electronic
devices). It must be paid attention that the voltage for such loads are sufficient. This can be supervised by a voltme-
ter.
The voltmeter should be always installed behind the change over switch generator/land power, so that each voltage
source is shown. No further voltmeter is provided for the generator itself.
If additional loads are switched on, the voltage must be controlled in each case at the voltmeter. Sensitive devices
must be switched off so long, until the voltage exceed the critical parameter.
Under certain circumstances the generator provides overvoltage. This arises if the number of revolutions of the
generator is increased. Changing the number of revolutions may be made only with a tachometer and/or a voltmeter.
If sensitive and/or valuable devices are used, which are to be protected against this risk, an automatic overvoltage
protection must be mounted. (voltage control with disconnection).
7.4.2 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 stopped). Such a relay with contactor can be obtained from the installator or as a complete unit from
your Panda dealer.
During any operation at the generator all load 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 acci-
dentally activation of the booster capacitors.
Re-connect the connections if the electrical supply lines in the AC-control box were also be disconnected.
The generator can’t be damaged by an overload because the winding is overload- and short-circuit safety. But
damages are possible in the periphery. Especially connected loads are endangered because a lower voltage can
damage them by order.
7.5 Low Generator-Output Voltage
If the produced alternating voltage is too low, switch the load off, in order to relieve the generator. Mostly the problem
already solved. If the output voltage is still too low, even if all loads are switched off, the generator runs without load,
you can assume one or more condensers are defective.
