3. INTRODUCTION

On delivery inspect the generator to check it has not been
damaged during transport or that no parts are missing.

3.1 Control of ID plate

The generators can be identified by their ID plate. This should
be controlled and compared with the order specifications.

REGULATOR SYSTEM
The generator is equipped with a compound transformer
that regulates and support the generator output voltage. One
of the windings of the compound is connected in series with
the stator auxiliary winding, which has a star connection; it is
also connected to a three-phase rectifier bridge. It provides
for rectifying the current for the rotor, which produce the flux
to induce the voltage in the stator windings. The other one
winding of the compound is connected in series to the main
windings of the generator. Thanks to this regulation system,
the voltage of the main winding is adjusted according to the
current supplied by the generator.

5. GENERAL MECHANICAL AND ELECTRICAL
SPECIFICATIONS FOR COUPLING WITH ENGINE
As an independent unit, designed to be built into a electricity
generating set, it is impossible to apply all the signal decals
on the generator during production. These decals, indicating
a potential hazard or risk due to live components are
supplied loose and have to be applied by the constructor
of the generating set in the positions indicated in the figure,
once assembly of the whole set has been completed.
This generators are designed to operate at a temperature
between -20°C and 40°C and at a maximum altitude of
1000m at s.l.
The nominal performance indicated on the plate refers
to operation within these temperature and altitude limits.
Contact our Technical Office for operate outside these
parameters.
At temperatures over 40°C and/or altitudes above 1000m at
s.l. a derating should be expected (see table).
