Description
Guard locking type
STP4 | Open-circuit current principle, guard locking by control of AS-i output 0. Release by spring force. |
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 ÜK |
Evaluation is performed via a safety monitor.
AS-Interface outputs
D0 | Guard locking solenoid |
D1 | LED red |
D2 | LED green |
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
This 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.
