Description
Guard locking type
CTP‑L1 | Guard locking actuated by spring force and power-ON released (closed-circuit current principle). |
Control of the guard locking solenoid
The guard locking solenoid can be controlled via AS-Interface bus bit D0 or via the auxiliary power.
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 |
LED function display
- The ASI LED indicates the state of the ASi bus.
- The STATE LED indicates the state of the switch.
- The LOCK/DIA LED indicates if the door is locked and whether a fault has been detected in the switch.
