OPERATION.01

6300/6310 Treadmill Electronics Repair Manual – Operation

6300/6310 Power/Signal Flow Explanation

1. AC voltage travels through the power cord, fuse, on/off switch, EMI filter, into the drive board.

2. AC voltage travels from the drive board to the transformer. The t ransformer outputs lower levels of AC voltage.

3. The drive board processes the AC voltage into DC voltage for use by the display, drive motor, and incline motor.

4. When the user presses a key, a signal travels from the keypad to the main program in the display, where it is
processed.

5. The display board sends a command via the ribbon cable to the drive board.

6. The drive board provides DC voltage to motors as directed by the display. For example, when you press
the Speed Up key, the signal travels from the display to the drive board via the ribbon cable; the drive board
emits voltage for drive motor operation. Similarly, when you press the Incline Up key, the drive board emits
voltage for incline motor operation.

7. On both the drive motor and incline motor are sens ors which tell the display about motor operation. Thei r signals
travel to the drive board, up the ribbon cable, to the display.

8. On the drive motor is an optic sensor. As the drive motor rotates, the opt ic sensor wheel rotates. The sensor
detects the difference between optic wheel teeth and spaces, thus indicating speed.

9. On the incline motor is a variable resistor (VR). As the incline motor turns, the VR turns, and its output voltage
changes, thus indicating the incline position.

10. The display uses sensor signals to determine whether to command the drive board to continue providing or
shut off power to the motors.

The Role of Other Parts

1. The inductor ensures steady current to the drive motor.

2. The thermal fuse on the drive motor is activated if the motor becomes too hot. When the thermal fuse is
activated (the circuit stops conducting), the “service required” indicator on the display lights.

3. The Electro Magnetic Irradiation (EMI) filter prevents interference to other products.
