Guard locking type
| STP3 | Closed-circuit current principle, guard locking by spring force. Release by control of AS-i output 0. |
Control of the guard locking solenoidThe guard locking solenoid is controlled by the control system via AS-Interface bus bit D0. It is only supplied from the AS-i bus; an additional supply of auxiliary power is not necessary. The current consumption with solenoid switched on is 400 mA.
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
| D0 | Guard locking solenoid |
| 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 releaseIs used for releasing the guard locking with the aid of a tool. To protect against tampering, the auxiliary release is sealed with sealing lacquer.
