Therefore, a remote control device was developed to meet the requirements for safe and reliable operation of the equipment. Utility Model Content

[0027] (1) Control Circuit Analysis

[0028] The control circuit is connected to the upper side of the 2P circuit breaker QF4 at 220V. The lower side of the 2P circuit breaker QF4 is connected to the L and N terminals of the PLC, and also to the upper side of the rectifier bridge.

[0029] The PLC input terminal uses a 24V DC power supply. The wiring method is to connect the negative terminal of the rectifier bridge to the PLC terminal 1M, and the positive terminal of the rectifier bridge to the common point L+ of receivers S1, S2, S3, S4, S5, and S6. S1 to S6 are connected to the PLC input terminals I0.0, I0.1, I0.2, I0.3, I0.7, and I1.0.

[0030] In this device, the PLC output terminals 1L, 2L, and 3L are connected to the PLC's L terminal.

[0031] Under the intelligent control of the PLC, the PLC receives signals from the remote controller to realize the movement of the trolley platform and the lifting and lowering of the bridge. When the remote controller sends a forward signal, the S1 contact closes, the PLC contact I0.0 receives the signal, and through the intelligent control of the PLC itself, the contact Q0.2 outputs a signal, the contactor KM1 is energized, the motor rotates, and the trolley platform moves forward.
