tHe eCo28 alternator operators' Handbook
Important
The starting, running and maintenance
and repair operations must be carried
out by skilled personnel who have read,
and understood, the safety instructions
earlier in this handbook.
Particular attention must be given to
the description of these two symbols in
"Section 02. Safety Precautions".
danGer
It is important to ensure that all the
necessary precautions to prevent
an inadvertent starting of the set
during maintenance, fault finding
and repair operations have been
taken.
5.1 CleanInG tHe alternator
Prior to approaching or touching the
alternator, ensure that it is not live and
it is at room temperature; at this stage
it is possible to clean it on the outside
using compressed air.
The inside of the alternator must not
be cleaned with compressed air as this
process could lead to short circuits or
other damage.
The standard protection degree of
the alternator is IP21, therefore the
use of fluids for cleaning could have
a detrimental effect, or cause short
circuits.
5. routIne maIntenanCe
danGer
Under no circumstances must
hydro-cleaners or detergent fluids
be used for cleaning purposes.
5.2 bearInG lubrICatIon
The alternator is fitted with sealed
bearings which have been packed with
SKF28, or similar, grease on assembly.
No maintenance is necessary for their
entire working life.
5.3 unusual noIses
The operator should check for any
anomalous noises which can be
detected. If such a noise is heard, stop
the set immediately and investigate
the noise.
noise and Vibration
It is recommend that users regularly
check for the correct functioning of
the alternator, and to verify that there
are no anomalous noises or vibrations;
their presence might indicate bearing
damage or wear.
The alternator itself has no particular
vibration since the rotating parts are
perfectly balanced. Provided that
the rotor balancing has not been
altered and that the rotor bearings
have not been damaged, vibrations
in the generator set may occur due to
alignment of couplings, due to stress
upon the engine, or to vibration mounts.
5.4 WIndInG resIstanCe
Assessment of the windings condition
after long periods of storage or
inactivity.
