Ismertetés

Approach direction

Horizontal

Can be adjusted in 90° steps

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.
