17. SAFETY PROTECTIONS AND TROUBLE SHOOTING
17.1 SAFETY PROTECTION
1. When operating, if the machine does not operate normally, press the STOP key. The rotating wheel
will stop immediately.
2. If the protection hood is not laid down when you press START, the wheel will not rotate.
3. If the protection hood is lifted while the machine is rotating, the rotating wheel will stop
immediately.
17.2 TROUBLE SHOOTING
1. If the shaft does not rotate after pressing START and the LED display shows “Err-1-”: check the
motor, power supply board, computer board and cable connections.
2. If the main shaft continues rotating for a long time without stopping after the balance test
finishes: check brake resistance, power supply board, computer board and cable connections.
3. If balance test already end, balancer still rotates for a long time, does not brake, check brake
resistance, power supply board, computer board and cable connections.
4. There is no display when the machine is turned on or the machine displays Figure 17-1:
Check whether power switch indicating light is flashing. If not, there is a problem with the power.
Otherwise, please check the power supply board, computer board and the cable connections. Self-
calibrate the machine or adjust the a-value sensor, or replace the sensor.
5. After measuring the rim, the display shows a difference in rim data. Self-calibrate the machine.
6. Usually a precision problem is not caused by the balancer machine. It is probably because of
incorrect wheel installation, or inaccurate counterweights, or inaccurate counterweight of 100
gram for balance self-calibration. Please store the original equipped 100 gram counterweight
properly, it is for self-calibration only.
7. Instability and poor repeatability of data are not usually caused by the balancer machine. It is
probably because of wrong wheel installation, or not firm or unleveled ground. Please secure the
machine with anchor bolts.
