Operating Instructions

Transponder-Coded Safety Switch CTP/CTA-L1/2-BP

12

(translation of the original operating instructions) 2537377-01-05/21

7.1.2.  Actuating auxiliary key release

On devices with auxiliary key release (can be retrofitted), simply turn the key to release. Function as for auxiliary release. 

For mounting, see the auxiliary key release supplement.

7.2. 

Emergency release

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

Important!

 

Ì

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

without tools.

 

Ì

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

cy.

 

Ì

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

 

Ì

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

the control system.

 

Ì

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

 

Ì

The emergency release meets the requirements of Category B according to 

EN ISO 13849-1:2015.

 

Ì

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

 

Ì

Check the release function every time after mounting.

 

Ì

Observe the notes on any enclosed data sheets.

7.2.1.  Actuating emergency release

 

Ì

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

outputs to generate a stop command.
The guard locking signal OL is switched off; the door position signal OD can assume an undefined 

state. Open the guard and close it again after resetting the emergency release. The device will 

then operate normally again.
