Guard locking type
| STA3 | 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. In addition the 24V connection can be switched safely.
AS-Interface inputs
| D0, D1 | Door monitoring contact SK |
| D2, D3 | Solenoid monitoring contact UK |
Evaluation is performed via a safety monitor.
AS-Interface outputs
| D1 | Red LED |
| D2 | Green LED |
LED function display
- The Power LED indicates the operating voltage on the bus.
- The Fault 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 release
Is used for releasing the guard locking with the aid of a tool. To protect against tampering, the auxiliary release is sealed with sealing lacquer.
Escape release (C1993, long actuator shaft)
This is used for manual release of guard locking from within the danger area without tools. With identification of On/Off position.
