Overload control unit
All generators are fitted with an overload control unit. This equipment consists
of an optical display on the front side of the generator (fault display) and a
corresponding signal to the ready / fault message socket [changeover con-
tact].
Function:
If the generator rated power, i.e. more than 100%, is exceeded, the
frequency search process function is triggered automatically. This means
that no continuous power output is guaranteed from this point onwards. The
fault LED starts to
flash
when this overload threshold is reached.
Simultaneously, the fault indicator relay is set. In this way, an electrical control
is possible as well as the optical control. The overload display is automatically
reset with the subsequent start impulse or by pressing the test button
(optional).
However, if the fault LED is lit with a
steady
light, this can be caused by
several things (defective secondary fuse, generator fault, incorrect
adjustment). For this, also see
Table 7.7.1:
faults and fault resolution and 7.7.2
fault diagnosis diagram.
The generator fault can be reset by switching off
and then switching the ERW generator on again.
