3.8. SPEED SENSOR
Only for models: POWERED.
This consists of a magnetic induction sensor which detects the heads of the Electromagnetic brake disk
fixing screws.
3.9. POWER ENTRY MODULE
Only for models: POWERED.
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 footboard.
WARNING: The maximum current extractable from the output of power entry
module is 7A. This places an upper limit on the number of machines that can be
connected together: do not connect more than N°8 equipments with a 220Vac mains
supply and N°5 equipments with an 110Vac mains supply. If other types of machines
are connected together, the maximum number is determined by their current draw.
3.10. ALTERNATOR
Only for models: SELF-POWERED.
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 200 VAC for
higher pedalling speeds.
Furthermore, analyzing the frequency of the AC voltage generated, it is possible to deduce the speed
of rotor’s rotation and then to deduce the user speed.
