Q: the detection method of power regulator is:

Answer: 1) connect the load light bulb to terminals M1 and M2, connect the power cord to terminals L and N.

2) electricity test, automatic state to observe the brightness of tungsten filament and the voltage at terminals L and N vary with the change of 0-10V.

3) electricity test, manual state to observe the brightness of tungsten filament and whether the voltage at terminals L and N varies with the rotation of knobs.

Q: how to determine whether a circuit breaker is malfunctioning?

Answer: 1). The fast identification method of multimeter: press the red button of the thermal relay and measure a pair of relative normal opening and closing ends with the access files. The normally closed points show infinity, indicating that the circuit breaker is good.

2). Press the green button of the thermal relay, and put the multimeter on the measuring path stop, and measure a pair of relative normal opening and exit ends. If the beep sound is issued and there is a fixed resistance, it means that the circuit breaker is good.

3) when the load current exceeds the rated current of the motor protection circuit breaker, it will automatically disconnect, so that the load contactor coil will be disconnected from the power to protect the load.
