3.1.9. SPEED SENSOR
Only for 500, 700 and 700WTVversions.
This consists of a magnetic induction sensor which detects the heads of the brake disk fixing screws.
On the self-powered machine, the speed sensor is directly built-in on the alternator (see paragraph
3.1.11. “Alternator”).
3.1.10. POWER ENTRY MODULE
This is a module consisting of:
• power inlet socket;
• power outlet socket;
• fuse-holder for protecting line voltage and neutral with two 3.15A fast-blow fuses.
It is situated on the side of the rear platform.
WARNING: The power entry module has a maximum current rating of 10 A. This places an
upper limit on the number of machines that can be connected together. Therefore, do not
connect more than 6 equipments with a 220 VAC mains supply, or 3 equipments with a 110
VAC mains supply. If other types of machines are connected together, the maximum number is
determined by their current draw.
3.1.11. ALTERNATOR
Only for 500SP and 700SP versions.
The alternator consists of a stator winding whose rotor is put into rotation by the movement of the
pedals, generating the voltage necessary for the machine’s operation.
Depending on the rate of pedalling and the resulting speed of rotation, it generates an alternating
voltage which ranges from approximately 15-17 VAC at about 30-35 RPM to over 40 VAC for
higher pedalling speeds.
The alternator has a built-in speed sensor which provides to the Brake Board the speed signal.
