Safety access control unit

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

The device features an integrated lockout mechanism with optional escape-release handle. The unit can be mounted on frames, grilles or profiles, while 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, enabling it to be used for interlocking, guard locking, escape release and machine functions such as start/stop and emergency stop.

The basic system complies with safety level e or SIL3 for protection against tampering. An LED display provides continuous system status information.

The optional escape release enables persons to exit the danger area quickly. When personnel are working in the restricted area, the bolt tongue can be locked open with up to three padlocks in the integrated lockout bar, preventing unintentional activation of the interlocking/guard locking.
