8.2. Emergency release (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 release manually from outside the protected area

without tools.

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

cy.

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

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

The emergency release 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.

Observe the notes on any enclosed data sheets.

8.2.1. Actuating emergency release

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 monitoring output OL is switched off; OD/OT indicates the current state of the guard. Open the guard and close it again

after resetting the emergency release. The device will then operate normally again.

8.3. Lockout mechanism

If the lockout mechanism is pivoted out, the bolt tongue cannot be extended. The lockout mechanism can be secured with

padlocks (see

Fig. 8

). This is intended to prevent people from being locked in unintentionally. The lockout mechanism does

not fulfill any safety function.

To pivot out, press the grooved part (possible only with bolt tongue retracted).
