Together with the following peripheral equipment the PMC-R controller forms an individually per customer order designed control system for Longwall automation. ● SolenoidDriver Board (minimumone perRoof Support) ● Pressure Sensor ● Reed Rod ● Proximity Switch ● IR Transmitter and Sensor ● LED Warning Light ● IS Power Supply ● Diverse Data Coupler ● 3D-Tilt Sensor and 3D-Tilt Monitor ● Double Solenoid Valve Such a PMC-R control system consists typically of more than a hundred similar subsystems set up by a PMC-R controller, solenoid driver, sensors, and valves per roof support and one time used hardware at the gate ends as server controllers, IPC, communication modules, chain tensioner, etc. ● Wide range of sensors and multiple solenoid drivers ● Easy diagnosis through communication between PMC-R controls ● Various auto sequences ● Automated conveyor push modes ● Conveyor pullback functions ● Automated water spray functions Main Features PMC-R Control System ● “Distributed Intelligence in each shield”

● Outrigger steering for conveyor steering (mostly plow faces) ● Automation of: – Block anchorage – Flipper – Sliding canopy – Gap shield – Several steering cylinder automation modes depen- dent on roof conditions Via a decentralized visualization and control unit at the face and/or the surface supports MineStar capabili- ties, especially HEALTH for Longwall. The entire PMC-R system provides different global certifications: ● Europe: ATEX ● U.S.: MSHA ● Russia: EAC/Ex ● Australia: IECEx, ANZEx ● China: MA ● More certifications on demand Solenoid Driver Module The PMC-R solenoid driver module is placed at a dis- tance from the PMC-R in accordance with the modular concept. The solenoid driver module can activate up to 22 valve functions, additional lights and sound modules or relays. As well, additional sensors could be read in by the solenoid driver module.
