Description

Approach direction

Horizontal and vertical, can be adjusted in 90° steps. Increased overtravel with horizontal approach direction.

If increased play is required when the door is closed, an actuator with overtravel is available. This actuator allows the door to move slightly in the actuating direction when closed. This is important, for example, if safety doors have a rubber buffer as an end stop. An actuator with overtravel can reduce the permanent pressure of the compressed rubber buffer. This reduces the load on both the switch head and the door mechanism.

Guard locking principle

Operating current (power to lock): In the case of a safety guard with guard locking according to the open-circuit current principle, the safety guard is locked until the power supply to the guard locking solenoid is break-before-make. The guard is unlocked by spring force. This is also referred to as electrical guard locking.

Control of the guard locking solenoid

The guard locking solenoid is controlled via AS-Interface bit D0.

Auxiliary voltage

The ASi auxiliary voltage is required to supply the guard locking solenoid.
