7.4.
Wire front release (bowden)
Release via a pull wire. Depending on the type of attachment, the wire front release can be
used as an emergency release or escape release.
The following applies to non-latching wire front releases:
If the release is to be used as an emergency release, one of the following measures must be
taken (see EN ISO 14119:2013, section 5.7.5.3):
Ì
Install the release so that it can be reset only with the aid of a tool.
Ì
Alternatively, resetting can be realized at the control-system level by means of a plausibility
check (status of the safety outputs does not match the guard locking control signal), for
example.
The emergency-release specifications in chapter
apply irrespective of this
information.
Important!
Ì
The wire front release meets the requirements of Category B accord-
ing to EN ISO 13849-1:2015.
Ì
The correct function depends on the laying of the pull wire and the
attachment of the pull handle, and this is the responsibility of the plant
manufacturer.
Ì
The actuator must not be under tensile stress during manual release.
7.4.1. Laying 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.
