Vantage 4000
Materials Required
* 4 pigtail cap crimps (wire size 18-12)
* 2 center conductor cap crimps (wire size 22-14)
* Strips of splice wrap
Crimp tool (customer supplied)
Knife (customer supplied)
Pointed tool (customer supplied)
Junction box (customer supplied)
A cable connection kit may be purchased through Eastech Badger that will include the * items above
(Part # 541874).
Trim each of the four cables at the junction box to 9 inches in length. Each of the four cables can now be
prepared as described in the sequence following:
Using a knife, trim two inches of the outer jacket from each cable. The wire braid beneath the outer
jacket must not be cut.
See "A".
Using a pointed tool, carefully comb out the outer braid of each cable as shown in "B". Form the combed
braid into a pigtail dressed to the side of the cable as
shown in "C".
Trim 1 inch of the inner jacket from each of the cables
as shown in "D". Again, use care not to cut the inner
braid beneath the inner jacket.
Using a pointed tool, carefully comb out the inner
braid "E" and form into a pigtail dressed to the same side
of the cable as outer pigtail in "F".
Remove 1/2 inch of insulation from the inner conductor of each cable. Cut the outer pigtail to the same
length as the inner pigtail on each cable. "G" depicts the completed preparation.
Cable Termination
Pull cables approximately 18 inches outside of junction box. Select one sensor cable and one cable from
the electronic enclosure and place them side by side as shown in Fig. 1. Twist each cable's outer pigtails
together, then the inner pigtails together and finally the center
conductors together to form the cable splice. In similar fashion,
connect the remaining sensor cable and the cable from the
electronic enclosure.
Identification of upstream and downstream sensor cables must
now be made. Connect a short wire from the center conductor
splice to the inner shield pigtail splice on the upstream sensor
cable. Using a multimeter determine the upstream sensor cable at
the electronic enclosure end by continuity measurement. Identify the upstream cable for later termination.
Remove the shorting wire and using the cap crimps supplied, crimp the larger caps on each spliced
pigtail and the small cap on the center conductor splice as shown in Fig. 2. Repeat this procedure for the
second cable.
At this point turn power on at the electronics and verify that an OK signal condition appears on the
display.
Turn power "OFF".
Using Splice Strips
1. Remove cover off of strips
2. Totally wrap strips tightly around all of the splice connections.
The finished splices should be coiled inside the junction box. When properly placed, the splices should
be clear of the junction box cover area. Proper sealing of the junction box is necessary for watertight
integrity.
This completes the triax cable splice connection.
