Transponder-Coded Safety Switch CET.-AP-…

(Translation of the original operating instructions) 2122242-04-05/18

7.2.

Emergency unlocking (can be retrofitted)

Permits opening of a locked guard from outside the danger zone without tools. For mounting, see the mounting supplement.

Important!

It must be possible to operate the emergency unlocking manually from outside the protected area

without tools.

The emergency unlocking must possess a marking indicating that it may be used only in an emer-

gency.

The actuator must not be under tensile stress during manual release.

The emergency unlocking must be sealed or the misuse of the release function must be prevented

in the control system.

The unlocking function meets all other requirements from EN ISO 14119.

The emergency unlocking meets the requirements of Category B according to

EN ISO 13849-1:2015.

Loss of the release function due to mounting errors or damage during mounting.

Check the release function every time after mounting.

Please observe the notes on any enclosed data sheets.

7.2.1. Actuating emergency unlocking

Turn emergency unlocking clockwise until it clicks into place.

Guard locking is released.

To reset, press the snap-in bolt inward using a small screwdriver or similar tool and turn

the emergency unlocking back.
The safety outputs are switched off when the emergency unlocking is actuated. Use the

safety outputs

to generate a stop command.

The monitoring output OUT is switched off; OUT D can assume an undefined state. Open

the guard and close it again after resetting the emergency unlocking. The device will then

operate normally again.

7.3.

Escape release (optional)

Permits opening of a locked guard from the danger zone without tools (see chapter

13.2. Di‑

mension drawing for safety switch CET.‑AP‑… on page 29

Important!

It must be possible to actuate the escape release manually from in-

side the protected area without tools.

It must not be possible to reach the escape release from the outside.

The actuator must not be under tensile stress during manual release.

The escape release meets the requirements of Category B according

to EN ISO 13849-1:2015.

7.3.1. Actuating escape release

Press the red release knob to the stop.

Guard locking is released.

Pull the knob out again to reset.
The safety outputs are switched off when the escape release is actuated. Use the safety outputs

to generate a stop

command.
The monitoring output OUT is switched off; OUT D can assume an undefined state. Open the guard and close it again after

resetting the escape release. The device will then operate normally again.
