Technical advantages and functional characteristics1. Integrating the main drive of rubber belt, the control of tensioning winch, the control of brake brake, the control of belt roller and 4.0kva lighting source;2. 8 combination is composed of 2×400A soft starting circuit and 4×120A +2×80A (total current no more than 400A) straight starting circuit, each circuit has independent monitoring and protection unit, 6 combination is composed of 2×400A soft starting circuit and 2×120A reversible +2×80A straight starting circuit, each circuit has independent monitoring and protection unit;3. Eight kinds of protection sensors can realize eight kinds of protection of the transport plane, with the intelligent positioning functions of deviation, pulling wire and longitudinal tearing;4. It has the function of fault alarm, and can realize the starting warning and fault alarm along the line by connecting with the intrinsically safe expanded broadcast telephone.5. PLC is adopted as the control core to facilitate centralized network control and support Profibus and industrial Ethernet communication;6. The embedded human-machine interaction interface can display the operating conditions of each device, motor current and temperature real-time display and fault state display, with the functions of fault record query, current and temperature curve query, etc.;7. The pilot circuit of the equipment is intrinsically safe circuit, which can effectively prevent spontaneous starting accidents caused by short circuit or grounding of the control circuit.
