The pm32 control unit solves all of the control problems in a mining face. The spectrum begins with the simple bidi-control functions through shearer and position dependent automation, to full-face automation. The pm32 is capable of controlling both increment plowing and automated shearer faces, and monitor face alignment and horizon control. The marco system ranges from sensors, cables and connectors to the control unit, which relays its data to the central computer.
Every active component is assembled in low power CMOS technology.
We offer a wide range of software applications which permit the customers to adjust control parameters. These allow the miner to influence the overall behavior of the face. The customer may decide in advance which parameters are to be adjustable. Software may be loaded underground simply by using a 4-inch long flash-eprom face loader, easy to transport and easy to handle.
The compact pm3/sg/c is completed by the mcv/8 valve solenoid control with 2 × 8 switch functions.They communicate with one single standard 4pole cable. Neighbor units and sensors are connected with the standard 4pole conm4 hose cable system.
The system contains a complete program of intrinsically safe sensors for mining applications.

The pm32 system may be quickly and easily extended with peripheral units (one cable) or with software for other functions (incremental plowing), e.g.:
Together with a main control unit the system offers the possibility of mine-wide monitoring, so that one can monitor shearer and plow functions together with functions of the conveyor and of power supplies.
