1-1. Explanation
2-1. Configuration
SPORTS ART INDUSTRIAL CO., LTD.
(1) When the incline is at or above 7%, the walk board slope is steep, and the walk belt
builds up momentum. Walk belt speed increases. The optic sensor detects the speed increase.
(2) Detecting the faster optic sensor speed, the drive board produces resistance, making
the belt speed return to normal.
(3) If the drive board resistance doesn’t take effect, the treadmill belt speeds up, and the
display shows ERR3.

3. Reason for ERR10
1. Turn power on; the motor immediately speeds uncontrolled; ERR 10 appears.
1-1. Explanation
The drive board IGBT short-circuited; The drive board immediately sends full power to the motor;
So the motor speeds uncontrolled; “ERR10” appears.

2. Test Procedure
2-1. Turn on power. Power switch lights. If it doesn’t light, inspect the main fuse.
2-2. If the drive board POWER LED lights, then the board is getting 5VDC on the VCC circuit.
2-3. If the POWER LED is not lit,
(1) Inspect whether power is coming into the board: Put multimeter to the 750 VAC setting.
Place probes on the drive board AC1, AC2 terminals as shown above. The multimeter should show
110V(N. America) or 220V(Europe).
(2) Inspect whether the F1 fuse is broken. Replace the fuse.
(3) Test whether the transformer is putting out voltage.
(4) Remove the 16-PIN cable. If the POWER LED lights, the display board is in question;
inspect the display board.
3. Circumstances of Malfunction
3-1. Turn on power. If the drive board POWER LED doesn’t light, the display board cannot light;
the display will be dark.
