S08 ALTERNATOR
ORDINARY MAINTENANCE
Air filter cleaning (if present)
Type of intervention Operator
PPE to wear Periodicity
Every 400 hours of use
Materials and equipments
Cleaning tools
DANGER!
Disconnect the alternator from the power supplies. The
drive motor must be off and unplugged from its power
supplies.
NOTE!
The intervention periodicity indicated refers to critical
environmental conditions. Adapt the periodicity based on
the actual conditions of use.
The air filters are accessories that are assembled on
customer request.
Air filters must be regularly cleaned because they hold
within a net that must be kept clean to guarantee the
efficiency of the filter and the consequent good operation
of the alternator.
The periodicity of intervention on the air filters will depend
on the severity of the conditions at the installation place.
However a regular inspection of these components will
allow you to determine if you should intervene.
1. Remove the grid (1).
2. Remove the filter elements (2) and clean.
3. Reassemble everything according to the initial
configuration.
Visual Inspection
Type of intervention Operator
PPE to wear Periodicity
Every 2500 hours of use
Materials and equipments
Workshop tools.
1. Check for the presence of anomalies such as cracks,
rust, leakages and any other anomalous event.
2. Check the tightening of the power cables and of the
regulator cables.
3. Check the state of the insulations of the power
cables and of the regulator cables (overtemperature,
rubbing).
Verification of winding state
Type of intervention Operator
PPE to wear Periodicity
Every 2500 hours of use
Materials and equipments
“Megger” Tester or similar to 500V in continuous voltage.
DANGER!
Disconnect the alternator from the power supplies. The
drive motor must be off and unplugged from its power
supplies
NOTE!
Before carrying out the verification disconnect the voltage
regulator (fig. A), the radio interference filters (fig. B) and
all the other potential devices electrically connected to
the windings to check.
