7.Place the new cable bundle in the cable track and connect all cables to their
appropriate positions. Close the cable track and wire tie the cables at the end
of it. Route the cable bundle through the hole in the top of the column.
8.Next locate the Laser On light and disconnect it. Remove this cable to the
top of the column cutting any necessary wire ties.
9.Route the new cable to the Laser On light and connect. Replace any wire
ties removed in step 5.
10.From the back of the arm column follow the cables vertically down and cut
all the wire ties holding the upper cable bundle to the other cable assemblies.
11.Carefully pull the upper cable bundle out towards the back of the arm and
down through the holes in the column.
12.Next cut the wire ties that hold the cables down near the bulkhead, these
are located in the lower rear portion of the arm.
13.Make sure the bulkhead connectors are labeled on both sides of the
bulkhead bracket and then disconnect them.
14.Next remove the two (16) pin Molex housing connectors that are attached
to the upper cable assemblies from the bulkhead bracket. Also disconnect the
large RS 232 connector from the bulkhead bracket. Pull the housings and the
Signal cable connectors out to work on them.
15.Use the mini Molex pin extractor tool and remove from bulkhead 1 pin16
and pin8. From bulkhead 2 (the lower connector) remove pin15, pin16, pin6,
pin7, and pin8.
16.Now remove the old cable bundle by pulling the cable out through the back
of the column. The old cable may now be discarded.
17.Next route the new cable bundle through the column wire tieing as you go.
18.Route the taped end of the cable through the hole at the bottom of the
column to the bulkhead area (follow the other cables that go to the bulkhead).
19.Carefully remove the masking tape from the cable exposing the mini Molex
pins and the Lemo connector. Note the orientation of the existing terminals in
the bulkhead connectors and the numeric labels at each hole of the
connector.
20.Replace the wires one at a time removing the wires from the old cable and
replace them with the wires from the new cable.
21.Insert the connectors into the bulkhead bracket the same way they were
removed and fasten the upper cable bundle with wire ties as original.
22.From the wire tie just fastened, the cables going into the arm column must
not have any slack in the cables (pull the cables from the column area to
remove any slack). Make sure that none of the cables hit any of the moving
parts in the narrow area where the cables come from the back of the column
out to the bulkhead.
