Temperature-Span Distance Application Information
Cable Pull Switches featuring broken cable detection require pre-tensioning in order to enable the RUN condition.
The relative expansion or contraction of the steel actuating cable when the ambient temperature increases or decreases must be
taken into account when pre-tensioning a cable pull switch.
The change in cable length with change in temperature can cause significant nuisance shut downs on longer runs.
Install the system when the temperature is at the mid point of the extremes. If a warehouse has a low temperature of 15,6 °C
(60 °F) and a high of 32,2 °C (90 °F), set up the system at the midpoint 23,9 °C (75 °F).
Use an endspring or another CPS at the opposite end of the cable span to double the temperature tolerance and to meet the
requirements of EN 418.
