Oil pressure switch
In order to be able to monitore the lubrica-
ting oil system, an oil pressure switch is
built into the system. The oil pressure
switch is on the back of the engine (below
the oil filter).

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 load 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.
A.1.2 Overloading of engine during longer operation
Please ensure that the genset is not overloaded. Overloading occurs when the electrical load
(demand) induces a load torque in the generator which is higher than that which the diesel drive
motor can provide. Overloading causes the engine to run rough, burn oil, creates excessive
exhaust (environmentally unfriendly) and even to stall. Extra caution should be practised with
multi-power units (single and 3-phase current generation) to avoid overloading the diesel drive
engine.
The generator should only be loaded at the peak
rated power for short periods only! A high peak
current is required to start many electrical
devices, especially electric motors and compres-
sors (from a still stand state
).
The height of the rated output (P) can taken from
the identification plate attached on the housing.
In order to guarantee a long life span, the conti-
nuous load should not exceed 80% of the nominal
load. By continuous output we understand the
continuous operation of the generator over many
hours. It is harmless for the engine to supply for
2-3 hours the full rated output.
