![CTP-L1-AS1B-U-HA-AE-SJ-126644 (Order no. 126644)](https://assets2.euchner.de/files/58/98/ast_735898_xl.png)
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.
Escape release
This is used for manual release of guard locking from the danger zone without tools.
