Cleaning the stator, rotor, exciter and diode bridge
The isolating components and the impregnation system are not at risk of damage from
solvents (see the list of authorized products above).
Avoid letting the cleaning product run into the slots.
Apply the product with a brush, sponging frequently to avoid accumulation in the housing. Dry
the winding with a dry cloth. Let any traces evaporate before reassembling the machine.
After cleaning the alternator it is essential to check the isolation of the windings.
Fault detection
If, when first commissioned. the alternator does not work normally, the source of the
malfunction must be identified.
To do this, check that:
-the protective devices are fitted correctly
-all connections comply with the diagrams in the manuals supplied with the machine
-the speed of the unit is correct. Repeat the operations instructions.
Mechanical Servicing
CAUTION
!
Cleaning the machine using a water spray or a high-pressure washer is
strictly prohibited. Any problems arising from such treatment are not
covered by our warranty.
The machine should be cleaned with a degreasing agent, applied using a brush. Check that
the degreasing agent will not affect the paint. Compressed air should be used to remove any
dust. If filters have been added to the machine after manufacturer and do not have thermal
protection, the service personnel should clean the air filters periodically and systematically, as
often as necessary (everyday in very dusty atmospheres). Cleaning can be performed using
water for dry dust or in a bath containing soap or detergent in the case of greasy dust. Petrol
or chloroethylene can also be used. After cleaning the alternator, it is essential to check the
winding insulation.
