•
Section which generates the current for the brake winding: varying the current produces a
proportional variation in the resistance of the brake. The excitation current supplied to the brake
is a function of the effort level selected on the display and the RPM value measured by the speed
sensor (angular velocity of the brake disk).
The board includes the following indicator LEDs:
LED name Color Description
LED1 green
if ON the board is supplying the brake winding.
if BLINKING the brake board is in an error condition.
LED2 yellow
if ON there is the +5 Vdc supply form the circuit
board.
and 2 jumpers:
Jumper Name Setting Description
JP1 open
JP2 open
3.1.7. B
RAKE
This is an eddy current brake, consisting of a flywheel mass and a flat copper disk that rotates in the
air gap of a winding to which it is connected. Variations in the winding current produce a change in
the resulting field, which consequently varies the eddy currents induced within the copper disk and
hence its resistance to movement.
The winding has a resistance of approximately 4.8 Ohm.
3.1.8. S
PEED SENSOR
This consists of a magnetic induction sensor which detects the heads of the brake disk fixing
screws.
3.1.9. P
OWER ENTRY MODULE
This is a block consisting of:
•
power inlet socket;
•
power outlet socket;
•
fuse-holder for protecting line voltage and neutral with two 3.15A fast-blow fuses.
Situated on the side of the rear platform. The Power entry module has a maximum current rating of
10A. This determines the maximum number of machines that can be connected together. Therefore,
do not connect more than 30 Bike Forma machines with a 220 VAC mains supply, or 15 machines
with a 110 VAC mains supply.
