Introduction
Before installing Mark 2 sensor cable (PN C6FG0902)
you MUST stabilize the cable. Prior to stabilization, the
center conductor may be bunched up in places, or
misaligned with the dielectric. Stabilizing the sensor
cable eliminates any bunching, and aligns the center
conductor with the dielectric. The result is uniform
detection sensitivity over the full length of the sensor
cable.
Intelli-FLEX Mark 2 sensor cable includes a solid center
conductor. You must handle the cable carefully to prevent any
twisting, bending, kinking or stretching of the cable.
Mishandling the cable will adversely affect the center
conductor, resulting in reduced sensitivity in the affected area.
Cable stabilization procedure
This procedure requires three people to complete (2 grippers
and 1 stabilizer).
1.
Carefully, unspool the sensor cable alongside the
fence in a long straight line (recommended).
Otherwise, unspool the cable in as long and
straight a line as site conditions allow, and then
form a gentle bend (with a large turn radius)
doubling the cable back toward the starting point.
Or, unspool the cable around a fence corner (with
a large turn radius). Ensure that the cable is NOT
pulled tightly against a fence post, or bent, as it
goes around the corner.
2.
Once the sensor cable is fully dispensed, check the
ends of the cable to verify that the center
conductor is free to retract or extend (i.e., the
cable end is not pinched, flattened, twisted, bent,
or distorted). If an end is damaged enough to
prevent the free movement of the center
conductor, you must cut off the damaged section.
There must be at least 30 cm (12 in.) of exposed center
conductor at each end of the sensor cable.
3.
Carefully remove 30 cm (12 in.) of the outer jacket,
shield and dielectric to expose 30 cm of the center
conductor at both ends of the cable.
DO NOT nick the center conductor.
Keep the sensor cable taut and in-line with the person who is
doing the waving and tapping during the stabilization
procedure.
4.
At each end of the sensor cable, one gripper firmly
holds the sensor cable by the black jacket with one
hand, while gripping the center conductor near
the end with a pair of pliers, with their other hand.
5.
Both grippers simultaneously apply 2.2 kg (5 lb) of
pulling tension to the center conductor while
maintaining a firm grip on the cable’s black jacket.
Both grippers must maintain the firm grip and equal pulling
tension for the duration of the stabilization procedure.
6.
The stabilizer picks up the sensor cable near one
end and gently waves it up and down a few times
(creating small waves, which travel approximately
3 to 5 m in both directions along the cable).
