Description

Approach direction

Horizontal

Can be adjusted in 90° steps

Guard locking principle

Open-circuit current (power on to lock): On a guard with guard locking based on the open-circuit current principle, the guard is locked until the power supply to the guard locking solenoid is interrupted. Unlocking is by spring force. The term electrical guard locking is also used.

Unicode evaluation

Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in.

Only the last actuator taught-in is detected.

Control of the guard locking solenoid

The guard locking solenoid is controlled via AS-Interface bit D0. In order to achieve safe control of the guard locking, the auxiliary voltage must also be switched safely.

Auxiliary voltage

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

AS-Interface inputs

D0, D1

Monitoring of the guard position

D2, D3

Guard lock monitoring

AS-Interface outputs

D0

Control of guard locking

LED indicator

The ASi LED indicates the status of the ASi bus.

The STATE LED indicates the status of the switch.

The LOCK/DIA LED indicates when the door is locked and whether a fault has been detected in the switch.
