CET4Open-circuit current principle guard locking by control of AS-i output 0. Release by spring force.
Control of the guard locking solenoidThe guard locking solenoid is controlled by the control system via ASInterface bus bit D0. AS-Interface inputs
D0, D1Door monitoring
D2, D3Guard lock monitoring
Evaluation is performed via a safety monitor. AS-Interface outputs
D0Guard locking
D1Red LED
D2Green LED
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.
