Oil pressure switch at diesel engine
The combustion engine is equipped with
an oil pressure control switch, which swit-
ches the engine off if the oil pressure
drops under a certain value.

A.1.1 Regulation of the generator voltage by the VCS
The output voltage of the generator is permanently measured by the VCS (approx. 20 times per
second!). As soon as by a consumer the voltage is affected, the speed regulation provides to
adapt to the changed power demand by appropriate change of the engine speed.
Not only by the excitation of the generator it is worked against to the initiating voltage drop, but
also by the raising of the number of revolutions whereby the drive potential improves.
