D.1.9Checking the Generator Voltage
In order to check the generator for faults, stop the generator and disconnect the connection
cables between generator and system. Remove the cables at the connection terminal of the
generator or, if installed, at the system distribution box. Make sure, there is no voltage on the
cables before disconnecting. The capacitors also are to be discharged.
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 Instructions"
in this manual.
Capacitors for
1. excitation (6x60µF)
2. booster (3x40µF)
After that, the generator should be restarted and the voltage checked at the terminals with a volt-
meter.
If the generator still does not supply sufficient voltage, the following steps must be undertaken:
1. Check the rev-speed of the motor. If the rev-speed is too low, the generator may not be able to
achieve full magnetic excitation and thus the required output voltage. If the engine rotational
speed is too high, the generator excitation will improve, but the generated voltage can also be
too high.
2. If the rev-speed is normal and the output voltage is still outside the acceptable range, the
capacitors should be inspected. Do not contact the capacitor terminals! Normally, however, it
is highly unlikely that more capacitors than one are faulty. In the event that one or more of the
capacitors are indeed faulty, the generated voltage will always be too low.
With the system (electrical load) disconnected, and with the generator motor running, a weak
generator voltage is a sure sign that at least one of the capacitors is faulty.
An unusually warm capacitor is also a sign that it is faulty or near the end of its life span.
