Description
Guard locking type
CET3 | Closed-circuit current principle, guard locking by spring force. Release by control of AS-i output 0. |
Control of the guard locking solenoid
The guard locking solenoid is controlled by the control system via AS-Interface bus bit D0.
AS-Interface inputs
D0, D1 | Door monitoring |
D2, D3 | Guard lock monitoring |
Evaluation is performed via a safety monitor.
AS-Interface outputs
D0 | Guard locking |
D1 | LED red |
D2 | LED green |
LED function display
- The ASI LED indicates the operating voltage on the bus.
- The State LED indicates if a fault has been detected on the AS-Interface bus.
- The green and the red LEDs can be controlled as required by the control system via the bus using bits D1 and D2.
Wire front release (bowden)
The wire front release permits remote unlocking of the guard locking via a pull wire. Flexible routing of the pull wire permits release of the guard locking in inaccessible installation situations.
Important: The wire front release (bowden) is not a safety function.
