ON BRAKE BOARD
This code indicates a low voltage error: this condition occurs when the +12 Vdc voltage drops
below 9.7 Vdc.
This error is caused by drops in the voltage output by the power supply section of the brake board,
as a result of defective components. If the error persists or recurs frequently, replace the brake
board.

ON THE BRAKE BOARD
This code indicates an overvoltage error: this condition occurs when the +12 Vdc voltage exceeds
13.7 Vdc.
This error is caused by surges in the voltage output by the power supply section of the brake board,
as a result of defective components. If the error persists or recurs frequently, replace the brake
board.

ON THE BRAKE BOARD
This code indicates an error in the EPROM of the brake board or a watch dog error: this condition
occurs when the board is unable to read the memory.
If the error persists or recurs frequently, replace the brake board.
6.4.6. E

ON BRAKE BOARD
This code indicates an error in the calibration of the brake board: this condition occurs when the
value of the calibration parameter read by the board is incorrect. In these conditions, the board
continues to function but will not necessarily produce the correct value of exercise resistance.
When this error occurs, replace the brake board.
