Shaker Part
Failure Reason analysis Solution
Shaking
starts
immediately
when power
is on
1) Electronic board broken
2) solid state relay breaks.
Disconnect no. 3 or 4 of solid state relay. If the
machine stops shaking, means electronic board
broken. If it's still shaking, means solid state relay
breaks.
No mixing
1) electronic board broken
2) solid state relay broken
3) shaking motor broken
4) Motor capacitance
broken
5) motor wire breaks.
1. Short circuit no. 1 and 2 of solid state relay, and see
if it's shaking.
(1) If it's not shaking, then observe if there is “buzz”
noise when motor is electrified.
- If yes, replace the motor capacitance. And replace
the motor if still not shaking after replacing the motor
capacitance .
- If no, please check wire. If it's normal, then change
motor.
(2). If it's shaking, check D11 light of the electronic
board when LCD shows “mixing”. If D11 light is on,
means no problem of the electronic board. If D11 off,
means electronic board broken.
No display
on LCD
1) LCD broken
2) Flat cable breaks 3)
Electronic board broken
4). Fuse broken
5)Transformer broken
1. Check Led 2 and D5 light on the electronic board
- If Led 2 not twinkle and D5 off, then check the
transformer and fuse.
- If Led 2 twinkle and D5 on, and there’s backlight
on the LCD , then replace the LCD.
- If Led 2 twinkle and D5 on, and there’s no
backlight on the LCD , then replace the flat cable. If
after replacing flat cable, there still no display on LCD,
then replace the electronic board.
2.Please check the transformer with multimeter.
Keyboard
doesn't work
1) Buttons broken
2) Connecting cable breaks
3) Electronic board broken
1. If it's only a certain buttons don't work, then check
if that button is broken.
2. If all buttons don’t work, then check flat cable. If flat
cable no problem, then replace the electronic board.
Shaking is
weak
Belt loose Adjust the belt accordingly.
Clamping
system
failure 1) Clamping motor broken
2) Electronic board broken
3) Synchronous
b elt
broken
4) Parameter incorrect
5) Sensor broken
1. Check the carbon brush of the clamping motor.
2. Replace the electronic board.
3. Replace the synchronous belt.
4. Reset the parameter
5. Replace the sensor
