Interlocking guard system

The Eichner MGB (multifunctional gate box) is an interlocking guard system for the protection of safety doors on machines and systems. Linked to machine controls, the opening of the access door via the MGB will be prevented until the machine has safely stopped.

The MGB features an integrated lockout mechanism with optional escape release handle and optional buttons and indicators can be integrated directly into the housing. The unit is easily mounted on frames, grilles or profiles and the handle can be mounted level or rotated 90, 180, 270° without disassembly.

Start, enable, emergency stop and other functions can be added to the basic handle/lock module to turn it into a small control terminal. This enables the unit to be used for interlocking, guard locking, escape release and machine functions such as start/stop, emergency stop, etc. The modular design means that additional features can be easily added at a later date.

Even the basic system complies with safety Level e in accordance with EN ISO 13849-1, or SIL3 in accordance with EN 62061, and EN 1088 for protection against tampering. An LED display provides continuous information on system status.

The optional escape release is intuitive to operate and enables persons to exit the danger area quickly and easily.
