Guard locking principle

closed-circuit current (power to unlock): In a safety guard with guard locking according to the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with current. The guard is unlocked by means of magnetic force. This is also referred to as mechanical guard locking.

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

AS-Interface outputs

D0

Activating the guard locking

D1

LED red

D2

LED green

LED indicator

The Power LED indicates the operating voltage on the bus.

The Fault LED indicates when an error has been detected on the AS-Interface bus.

The green and red LEDs can be controlled by the control system via the bus as required using bits D1 and D2.

Auxiliary release

The auxiliary release on the front allows access to the machine in the event of a malfunction, e.g. a power failure. It is unlocked using a tool or a key. The auxiliary release must be secured against misuse (sealing, laking).

Required accessories

Actuator is not included in the scope of delivery.
