PME300 is a controller designed to monitor and prevent slewing machinery moving into a user-defined zone. PME300+ provides the basic functionality of PME300 with the additional ability to work within a user-described complex shape or with a “virtual wall” at one or both sides of the equipment. Both systems are designed to control the machine within the horizontal (slewing) plane and do not control vertical movement. The operator will benefit from Prolec’s easy to use ‘Man Machine Interface’ MMI integrated within the foundation of PME.
