PVD control system using special control box to control, by the control box each equipment in the central control system (including the permanent magnet motor, frequency converter and its cooling system), and all the equipment in the system signal collection and processing (including the permanent magnet motor stator and bearing temperature, permanent magnet motor and frequency converter cooling system temperature, pressure, flow, etc.) for real-time protection system. Users only need according to the feedback signal of the control box are given start stop command, control box automatically according to the program start stop corresponding equipment, real time system for monitoring and protection, and the state of the system output. It can greatly facilitate the user to use PVD system, reduce the workload and connect quickly. At the same time, the control box reserves multiple communication interfaces and supports multiple networks, including industrial Ethernet, Modbus, Profibus and remote I/O.
The core component of the control box consists of a touch screen and a programmable controller (hereinafter referred to as PLC). Chain control of PLC is mainly responsible for the whole system, the scene of various protection signal chain and all equipment status signal into the PLC input point, by PLC according to the operating instructions output signal after logic operations for start-stop control field device. System status and parameters are displayed in real time through the touch screen, so that users can know the system status in time.
Control mode of control box
The control box has three control modes: remote control, manual control and locking
A) remote control: this system receives control instructions from remote signals such as the main control of the belt conveyor, and automatically stops all devices according to the procedure.
B) manual: it is mainly used in the debugging stage of equipment. It can also be used as an emergency measure for temporary production.
C) locking: no starting.
