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.

No start up Power on indicator does not
light.
1. Inspect the power cord connection.
2. Inspect all cable connections.
3. Inspect the fuse, the fuse holder, and the power
switch.
4. Drive board components have an electrical short.
Replace the drive board.

2. Drive board
No start up Power on indicator lights but
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.

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.

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 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.
