Description
Guard locking type
CTM-I2 | Open-circuit current principle: Guard locking by control of AS-i output 0 and release by spring force. |
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, D2, D3 | Door 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 LOCK LED indicates the state of the guard locking.
- The STATE/DIA LED indicates the state of the switch and possible errors.
Auxiliary release
This is used for releasing the guard locking with the aid of a tool. The auxiliary release must be sealed to prevent tampering (for example with sealing lacquer).
