Ismertetés
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
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 | Positively driven contact 1 |
D2, D3 | Positively driven contact 2 |
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.
