Brochure, System description UH 6900 SAFEMASTER W - Group mode, File: pdf, File size 4 MB

The radio controlled safety module UH 6900 in group mode is an innovative wireless safety system to protect man and machine. A feature of the wireless safety system is its safety-oriented uni-directional radio transmission for transmitting signals between one wireless safety module as group control device and one ore more group receivers so that the two separate safety devices, each of them installed on a different machine part that is not connected to the other by wires (for example, moving machine parts), work together as one system.

Therefore SAFEMASTER W radio controlled safety modules are intended for the wireless remote control of machines and plant parts that used to be controlled by cable. Their usage is only restricted by valid safety instructions that prohibit, for example, staying under suspended loads.

The radio controlled safety module UH 6900 group receiver always works together with a UH 6900 group control device. The safety related output contacts are either controlled via radio from the group controller or by local e-stop systems.

Typical applications are:
• Hazard areas where protective equipment is necessary for the safety of persons but where wiring is impossible or not reasonable, for example in applications with extremely wide-spread, extensive hazard zones;
• Mobile and stationary plants and equipment, for example large machines, assembly halls and scaffolds, conveyor belts, high-rack warehouses, warehouses, forklifts, etc.
• The radio transmission range is up to 800 m
