Operating Instructions for Rope Pull Switches

Selection of system components
A tensioner spring must be installed on the thrust bearing in order to ensure proper and safety-compliant
implementation of the pull rope system. This is a precondition for direction-independent tripping at any point
along the rope length. In order to achieve fast and simple compliance with this requirement, we recommend the
use of EUCHNER tensioner springs with integrated overstretch protection (see Table 1). Additional fixing and
installation materials as well as ropes are also optionally available. A detailed overview is provided in the
section Accessories.
