Description

Approach direction

Horizontal

Can be adjusted in 90° steps

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.
