5.3 - Accessories
• 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.
• 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.
