Our technical support service will be pleased
to provide any additional information you
may require.
When ordering spare parts, you should
indicate the complete machine type, its
serial number and the information given on
the nameplate.
Address your enquiry to your usual contact.
Part numbers should be identified from the
exploded views and their description from
the parts list.
Our extensive network of service centres
can dispatch the necessary parts without

5.3 - Accessories
5.3.1 - Space heater for use when
stopped
The space heater must run as soon as the
alternator stops. It is installed at the rear of
the machine. Its standard power is 250W
with 220V or 250W with 110V on request.
Warning: the power supply is present
when the machine has stopped.
5.3.2 - Temperature sensors with
thermistors (PTC)
These are thermistor triplets with a positive
temperature coefficient installed in the
stator winding (1 per phase). There can be a
maximum of 2 triplets in the winding (at 2
levels: warning and trip) and 1 or 2
thermistors in the shields.
These sensors must be linked to adapted
sensing relays (supplied optionally).
Cold resistance of cold thermistor sensors:
100 to 250 Ω
per sensor.
5.3.3 - Connection accessories
- 6-wire machines : coupling (F)
3 flexible SHUNTS
- 12-wire machines : coupling (F)
3 flexible SHUNTS
After operational testing, it is essential to
