Safety key malfunction Put safety key in place.

Display has no reaction.

“Safety key” appears on the

display.

1. Inspect the cable connections on the lower part of

the display and safety key.

2. Inspect the safety key magnet.

3. Inspect the safety key board.

the display does not light.

1. Inspect all cable connections, including connector

cables.

2. Inspect whether drive board LED2 lights:

a. If LED2 lights, inspect and test the transformer

fuse.

3. Inspect whether LED1 on the display lights.

a. If LED1 does not light, inspect the data cable from

the display to the drive board.

b. If LED1 does light, inspect the display program

IC. Re-install the display IC.

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.

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 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.
