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 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 specications in chapter 7.2 on Page 13 apply irrespective of this infor-
mation.
Important!
Ì The wire front release meets the requirements of Category B according to ENISO13849-1:2015.
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 (100mm) and minimize the number of bends.
Ì The switch is not allowed to be opened.
Ì Please observe the notes on the enclosed data sheets.
8. Changing the approach direction
1. Remove the screws from the safety switch and take the head off the safety switch.
