•
A tensioning spring is required to ensure compliance with direction-independent actuation of the wire rope and must be
installed on the load bearing structure (for example, machine frame, wall, etc.)
•
Temperature affects rope tension. The wire rope expands (lengthens) when temperature increases, and contracts (shrinks)
when temperature decreases. Significant temperature variations require frequent checks of the tension adjustment
•
Do not exceed the maximum specified total wire rope length. This length may be reduced due to temperature variations as

WARNING:
•
Properly install the device
•
Failure to follow the installation instructions can result in ineffective or non-operation of the Banner
device, which could create an unsafe condition resulting in serious injury or death.
•
Follow all installation instructions.
Installation Procedure
1. Mount the switch securely on a solid, stationary surface that can accommodate the forces of pulling the rope.
on p. 9 for the mounting hole pattern (4 x M5, Max. torque = 2 Nm).
2. At the opposite end of the rope span, fasten an individual eye bolt (such as RPA-EB1-1) or the Tensioning Spring Assembly
(RPA-S4-1 or RPA-S6-1) eye bolt to an anchor that is solid and stationary, and can withstand the constant tension and pull
of the rope. Do not exceed the maximum length for the specific switch.
3. For applications using an
Individual Tensioning Spring
(RPA-S5-1 or RPA-S3-1), assemble the Spring Breakage
Protection Cable (such as RPAK-C2SBP-1) and the thimble/clamp loop at the end of the rope, as shown in
4. Keep the rope’s PVC cover intact along its complete length, except where it attaches to the clamps at either end. Use
Tensioning Spring RPA-S5-1 for the 25 m and the 38 m switches in straight line applications and RPA-S3-1 for 75 m
applications or in any application in which the direction changes.
4. For applications using a
Tensioning Spring Assembly
(such as RPA-S4-1 or RPA-S6-1), install the rope using the
following steps.
See
on p. 5.
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) Using the 4 mm hex wrench, tighten the set screw on the switch fitting.
