Guard locking type
CET4 | Open-circuit current principle guard locking by control of AS-i output 0. Release by spring force. |
Control of the guard locking solenoidThe guard locking solenoid is controlled by the control system via ASInterface 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 | Red LED |
D2 | Green LED |
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.
Auxiliary releaseIs used for releasing the guard locking with the aid of a tool. The auxiliary release must be sealed to prevent tampering (for example with sealing lacquer).
