Wire front release (optional)
Important:
Ì The wire front release is not a safety function.
Ì The wire front release is non-latching and therefore must not be used as an
escape release unless the machine manufacturer itself provides a detent
mechanism. The machine manufacturer must select and use a suitable re-
lease (escape release, emergency unlocking, etc.) for a specific application.
A risk assessment appraisal is required for this purpose. It may be neces-
sary to take specifications from a product standard into account.
Ì Loss of the release function due to tension on the actuator. The door must
not be under tension during release.
Ì The correct function must be checked at regular intervals.
The wire front release permits remote release of the guard locking via a pull rope.
Flexible routing of the pull rope permits release of the guard locking in inaccessible
installation situations.
On devices with monitoring output OUT, this is switched off; OUT D can assume an
undefined state. Open the safety door and close it again after resetting the wire
front release. The device will then operate normally again.
Mounting the wire front release
Important:
Ì Loss of the release function due to mounting errors, damage or wear.
Ì Check the release function every time after mounting.
Ì When routing the wire front release, ensure that it operates smoothly.
Ì Observe the min. bending radius (100 mm) and minimize the number of
bends.
Ì The switch is not allowed to be opened.
Ì Observe the notes on the enclosed data sheets.
