Description
Lockout mechanism
The lockout bar can be used to prevent maintenance personnel from being unintentionally locked in the danger zone, for example.
Important: The lockout bar is not a safety function..
This device with lockout bar possesses no auxiliary release.
Guard locking type
CET4 | 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.
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 |
D1 | LED red |
D2 | LED green |
LED function display
- The ASI LED indicates the operating voltage on the bus.
- The State 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.
Escape release
This is used for manual release of guard locking from the danger zone without tools.
