3.4. BRAKE BOARD
Every Brake Board is divided up into:
1.
Power supply section which generates the low voltages used by the equipment: +5Vdc (used
only by high kits of the LED type) and +12Vdc (used by all types of high kits). Depending on
the equipment version, these voltage levels are originally generated from mains voltage (both
110Vac and 220Vac) or by a battery-generator.
2.
Section that communicates with the Display Board (high kit) on the RS-485 serial line in
order to manage:

the signals for controlling the resistance which needs to be supplied to the
Electromagnetic Brake;

the error messages relating to the Electromagnetic Brake;

the signals modifying the board's configuration parameters;

the signals displaying the memory of errors detected by the board;

the signals relating to use of the equipment (RPM, WATT, distance etc..)
3.
Section that generates the current for the winding of the Electromagnetic Brake: when the
current varies, the resistance supplied to the Brake itself also varies proportionately. The
excitation current supplied to the Brake varies according to the user power/torque requested
by the display and the number of revolutions detected by the speed sensor (RPM).
On the Brake Board there are some signal LEDs:
LED Name Colour Description
LED1 GREEN
If ON, the board is supplying power to the winding of the brake.
If it is FLASHING, there is a fault on the Brake Board and
there is no current on the brake.
LED2
YELLOW
(if board has
supplier code
EFI F10549)
If ON, the Brake Board is on.
RED
(if board has
supplier code
LASER
F04010)
During movement, the Brake Board is capable of detecting possible faults. Any possible errors are
detailed in paragraph: 6.4. “The Brake Board has detected an error”.
