THE "MT" SERIES REQUIRES POWER TO DEPLOY THE LOCK. 

When the proper voltage is applied to the A1 and A2 coil terminals the solenoid is activated and the pin is pushed into the actuator opening.

It is available in two models, the first being the "S11" which has a normally open cover switch contact that closes when the cover is opened or the "S02" model that has the opposite and the cover contact is open when the cover is open.

THE "FT" SERIES REQUIRES POWER TO RELEASE THE LOCK.  When the proper voltage is applied to the A1 and A2 coil terminals the solenoid is activated and the locking pin is pulled back from the actuator opening, therefore releasing the lock from it's fail safe spring return locked position. Even with a power failure the door or cover will remain locked. A manual release is also  provided. It is available in two models, the first being the "S11" which has a normally open cover switch contact that closes when the cover is opened or the "S02" model that has the opposite and the cover contact is open when the cover is open.

By reliable securing and interlocking of protective doors, the LS-ZBZ increases the safety standards for the protection of personnel and processes The LS-ZBZ operates according to one of two principles: on the basis of magnet-powered or spring-powered interlocking.

Using the magnet-powered design, the protective cover is interlocked when operational voltage is applied, and can therefore be opened directly in the event of power failure.

The spring-powered scheme ensures that the door or protective guard remains safely locked even in the event of power failure. The interlock is released when power is applied to the LS-ZBZ. This means that personnel are protected from overrunning machines. This variety of the LS-ZBZ only opens once the potentially dangerous movement has ceased. In an emergency, the protective guard can be opened using an auxiliary release mechanism.

Via a second switching contact, dangerous processes can be monitored from the control station.
