Generator Failure

Page 48 Panda_12mini_PMS_Digital_s00865_Installation manual.V02 - Chapter C: Generator Failure

23.1.07

C.5 Generator provides no Voltage

C.5.1 Rotor Magnetism Loss and "Re-magnetizing"

.ATTENTION! See “Safety Precautions” on Page vii.

With asynchronous generators it can be the fact that the generator can not build up indepen-
dently voltage after longer service lives, or, if it were switched off under full load. The cause lies in
the fact that the rotor lost its remainder magnetism.

This remainder magnetism can be restored in a simple manner by a DC battery.
In addition the „shore power“ must be switched off and any connection to a AC-
source must be interrupted.

Likewise the genset must be switched off, i.e. also the starter may not be opera-
ted. The power source selector is switched to "generator". Only the plug socket
must be connected with the generator.

Now the two poles of a 9V battery are connected with the plug socket or held to

the appropriate contacts in the on-board current distribution. Use not a battery bank or the gene-
rator starter battery, this could damage the coil. The DC voltage may be applied only for a short
time (1-2 seconds). In the coil the remainder magnetism is restored by the short current pulse,
and the generator can be normally started.

C.6 Starting Problems

C.6.1 Fuel Solenoid Valve

The fuel solenoid valve is located in front of the injection pump. It opens automatically, if the
„START“-button is pressed on remote control panel. If the generator is switched to "OFF", the
solenoid valve closes. It takes some seconds, before the generator stops.

If the generator fails to start, runs rough, does not reach the proper RPM, or does not stop pro-
perly, the first item to suspect in most cases is the fuel solenoid valve and should be inspected
first.

A check of the fuel solenoid valve by removing the plug from the fuel solenoid valve for a short
period whilst in operation (first remove the small retention screw) and replace it immediately. The
motor should "react immediately" by revving high. If the motor does not react sharply to the
reconnection of the solenoid wire, it is a sign that the solenoid valve could be faulty.
