Circuit breaker Q5 trips when the machine is switched on or during production.
Possible Causes or Resolutions:
- Measure voltages at all phases, even under load. It is possible that one phase did drop down, and this triggered the circuit breaker.
- Measure the current of each phase with a current clamp after Q5. If the measured value is below the value of the circuit breaker and Q5 still keeps tripping, the circuit breaker may be defective. Replace it.
- Maybe the parameter “Low bat voltage” (coming from Pacemaker) is set too low: That means that the contactor in the Pacemaker closes too early with a precharge voltage that is too low and therefore Q5 trips. To check this, please open a ticket to contact CanMan.
