NOTE:
All hardware is supplied by the user. The
switch mounting holes are on a mounting
pattern of 30 x 124 millimeters, and
accept M5 (#10) hardware.
Installing Model RP-LS42F-75LE or RP-LS42F-75LF
These models have their own internal turnbuckle and clamp to tension the rope and
to hold it in place. This innovative design provides for quick and easy rope fixing and
tensioning, and means no external turnbuckle is required, nor is any additional clamp
required at the switch end of the rope.
To install the rope at the switch end, strip away several inches of the cable covering, as
shown in Figure 2. Loosen the set screw on the switch fitting, using a 4 mm hex wrench.
Insert the cable into the center hole, and pull the cut end out from the side hole. When
the tension is correct, tighten the set screw to hold the rope firmly in place.
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 indicator window (see Figure 4).
This indicates sufficient rope tension. (Contacts 21/22 and 41/42 will close.)
Model RP-LS42F-75L: Turn the turnbuckle until the arrows are centered.
Models RP-LS42F-75LE
and RP-LS42F-75LF: Turn the shaft of the switch using an 8 mm wrench as shown in
Figure 4, until the arrows are centered.
Pull hard on the rope 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 after such a reset.
