7.4. Wire front release (optional)
Release via a pull wire. Depending on the type of attachment, the wire front release can be used as emergency release or
escape release.
The following applies to non-latching wire front releases.
If the release is to be used as 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 implemented at the control-system level e.g. by means of
a plausibility check (status of the transmitted code sequence/zero sequence does not
match the guard locking control signal).
The emergency-release specications in chapter 7.2 on Page 12 apply irrespective of this
information.
Important!
Ì The wire front release meets the requirements of Category B accord-
ing to ENISO13849-1:2008.
Ì The correct function depends on the laying of the pull wire and on 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 (100mm) and minimize the number of bends.
Ì The switch is not allowed to be opened.
Ì Observe the notes on the enclosed data sheets.
