C.3.2 Effects of a overload to the actuator
If the generator is overloaded the voltage falls on account of a not adequate motor power under
the nominal value. The actuator stays at the upper keystroke and tries to rev up the diesel engine.
An internal regulation limits the current to the actuator, nevertheless a longer overload can
damage the winding of the actuator. (short of the winding). The motor gets not strictly inoperative
but it can happen that the cranking torque of the actuator is getting weak. This has the consecu-
ence that the rev spindle can not be turned to all positions faultless. Therefore the voltage of the
generator is regulated not good or sometimes not at all.
If you notice that the spindle of the actuator doesn´t run faultless, first check if the aggregate was
overloaded for a short time and if thereby the winding of the actuator was damaged. Then the
actuator has to be changed.
Check the electrical fuse (miniature slow-to-blow fuse 1,6A) on the control printed circuit
board if the actuator will not turn at all.
Change this fuse (1,6A slow to blow)
The generator can’t be damaged by an overload because the winding is overload- and short-cir-
cuit safety. But damages are possible in the periphery. Especially connected consumers are
endangered because a lower voltage can damage them by order.
