Notes

Incline

position is

not correct.

Incline position on display

differs from actual position.

1. Inspect all cable connections.

2. Inspect drive board incline VR voltage across red and green

wires. Normal: 0% = 1.20 VDC, 15% = 3.57 VDC. If not,

recalibrate the incline VR.

3. If VR voltage fluctuates greatly, the VR is bad. Replace the VR.

If the VR voltage is correct but the height is incorrect, replace

the display board.

Key

malfunction

Key does not operate or

operates continually.

1. Inspect the soft key connection.

2. If the <program> or <change> key is bad, replace the upper

soft keys on the display.

3. If other keys malfunction, replace the lower soft keys on the

display.

1. Soft keys

ERR 1

Motor does not rotate, ERR

1 appears.

1. There is no power to the motor; the motor cannot operate.

2. Inspect the motor brushes.

3. Measure voltage from the drive board to the motor.

If there is no voltage, replace the drive board. If there is voltage,

inspect the following:

a. transformer voltage.

b. whether the EMG indicator lights.

c. whether IGBTs have an electrical short. Replace the drive

board.

4. Inspect motor brushes or the commutator.

1. Drive board

2. Motor brushes,

ERR 1 Motor operates, ERR 1

appears.

1. The program did not detect the optic sensor signal.

2. Inspect the CLK indicator on the drive board.

a. If the CLK indicator is not lit, clean or replace the optic sensor.

b. If the CLK indicator lights normally, inspect the data cable from

the display to the drive board. Re-install the display IC.

1. Optic sensor

ERR 3 Display speed differs from

actual speed.

1. Inspect KPH/MPH setting.

2. Inspect the optic wheel teeth.

3. Replace the optic sensor.

4. Replace the drive board.

Notes

ERR 7 ERR7 appears at startup. 1. Inspect the incline VR cable connection.

2. Usually ERR7 indicates the display is stuck at either the highest

or lowest position.

3. Inspect whether LED5 and LED6 light on the drive board. If lit,

the display or cable malfunction may be causing a malfunction.

4. Inspect whether the drive board emits voltage to the incline

motor. If not, replace the drive board.

5. Recalibrate the incline set or replace the incline set as a test.

1. Inspect the motor thermal switch wire

connection and the LED4

M-TEMP on the drive board. Feel the motor. Is it hot?

2

. If the motor is hot and the unit has been in use, turn off the unit.

Let the unit rest one half hour or more. Then turn off the unit.

3.The running belt and deck need to lubrication.

4.Inspect the running belt and deck.

5.if necessary , replace the running belt.

6. If steps above do not solve the problem, replace the motor.

1.Running belt
