When detecting standby signal, microcomputer gives structure to relay switch to cutoff the current, then standby power is eliminated so as to realize energy saving.
Temperature relay tests temperature of motor, if it exceeds rating temperature to send a signal, contactor cutoff main circuit to complete protection of motor.
温度继电器检测电动机温度,超过额定温度发出信号,接触器切断主电路,完成电机保护。

Respectively through the various contacts, in order to dial the corresponding limit switches and over current relay normally closed contacts, to see the ability to cutoff the control current.
