Brake Board - Technogym FORMA LINE BIKE FORMA DDC5 Series Technical Assistance Manual

3.4. BRAKE BOARD

Every Brake Board is divided up into:
Power supply section which generates the low voltages used by the equipment: +5Vdc (used
1.
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.
Section that communicates with the Display Board (high kit) on the RS-485 serial line in
2.
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..)

Section that generates the current for the winding of the Electromagnetic Brake: when the
3.
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:

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".

Colour
If ON, the board is supplying power to the winding of the brake.
GREEN If it is FLASHING, there is a fault on the Brake Board and
there is no current on the brake.
RED If ON, the Brake Board is on.
