a) Strip away a minimum of 100 mm to 150 mm (4 in to 6 in) of the red rope sheathing. Additional length of red sheathing
maybe required to be removed depending on total slack in the rope.
b) Using a 4 mm hex wrench, loosen the set screw on the switch fitting.
c) Insert the cable into the center hole in the clamp, pull the excess rope through, and loop the rope back through the
clamp.
d) Pull the cut end of the rope out from the side hole until there is no excess rope in the clamp.
e) Make sure that no red sheathing is within the clamping mechanism.
f) When affixing at the switch (with integral turnbuckle), after the rope has been strung the complete length, pull the cable
so that the approximate tension is achieved.
g) When the tension is correct, tighten the set screw to hold the rope firmly in place.
h) Make sure that the cut ends of the rope do not present a hazard (cutting, scraping, snagging, etc.). Electrical/plastic tape
or plastic tubing can be used to cover any sharp ends of the rope.

Tensioning the Rope
After the rope span components are installed, apply tension to the rope until the arrows in the tensioning indicator are centered on
the line in the tension indicator window. This indicates sufficient rope tension. (Contacts 21/22 and 41/42 will close.) Course
tensioning can be accomplished by pulling excess rope through the clamp until the tension indicator is approximately centered and
then re-tightening the clamp. It is recommended that tensioning be accomplished at a median temperature to accommodate
fluctuations.

:
a. Using a 17 mm wrench, make sure that the locking hex-nut is loose from the base of the switch.
b. Using the thumb wheel, rotate the shaft of the switch until the arrows are centered on the tension indicator.
c. Re-tighten the locking hex nut to the base of the switch (do not over tighten).

2. Reset the latch by pulling on the button until it catches in the armed position.

Approx. 10 mm (3/8 in.)
3. Pull hard on the rope until the switch trips, release, and reset the latch several times. If the arrows in the tensioning indicator
window do not return to the correct position (centered on the line in the window), further tighten or loosen the rope tension
as needed, until proper tension is shown.
4. Check the tension adjustment periodically to ensure proper operation.
