HMI Drill Rig Control Station
The L0WD HMI (Human Machine Interface) Control Station is an integrated graphics display and push-button control unit that is built into a rugged, stand-alone flameproof enclosure.
The product is intended to provide a user-friendly, and robust, user interface control station for mobile mining equipment that must be operated in so-called hazardous areas; where there is a risk of fire and explosion due to methane gas and coal dust.
The complete assembly is built into a self-contained flameproof enclosure (EX d Explosion Protection Certification); making it suitable for use in hazardous environments such as underground coal mining.

Brochure Additional Information
In this application, the HMI includes automation, control and safety functions for control and monitoring of the “E-Box” installed on the drill rig. The HMI communicates with the drill rig via a dedicated, local CAN bus. This communication link allows the HMI to turn on and monitor solenoids in the E-Box that control hydraulic drill rig functions. The HMI also forms part of the machine stop circuit. It monitors the stop circuit and shuts down drill rig if the stop circuit is opened by the machine control system or any hard-wired stop device on the machine. The also HMI contains a set of redundant (wired in series) stop relay contacts. These are opened if the operator pressed the latching stop button on the front face of the HMI station. These are also opened if the HMI detects an unsafe condition in the E-Box; such as a stuck solenoid spool or an illegal pressure feedback.
The HMI station also communicates with the machine host control system via the machine-wide CAN bus. The host control system supervises and monitors the HMI and drill rig control via CAN bus communication. This allows the machine control system to implement machine wide automation and safety functions; which include one or more HMI-based drill rig control sub-systems.
