CET3-AR-CRA-AH-50F-SH-C2467-129491 (Order no. 129491)

Description

Approach direction

Horizontal

Can be adjusted in 90° steps

Escape release

This is used for manual release of guard locking from the danger zone without tools.

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.

Safety switch

The device may be operated only in conjunction with the actuator CET-A-....

Important: The actuator must be ordered separately.

Unicode evaluation

Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in. Only the last actuator taught-in is detected.

Solenoid operating voltage

  • DC 24 V +10%, -15%

Guard locking type

CET3

Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid. The door position is also monitored. The door monitoring output OUT D is set to HIGH as soon as the actuator is above the extended plunger (state: door closed, guard locking not active). The output OUT D also remains set when guard locking is active.

Category according to EN ISO 13849-1

Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

  • Category 4 / PL e according to EN ISO 13849-1
  • The stated safety characteristics apply to any installation orientations of the safety switch.

Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.
