b) If the suspected boundary wire is long
(thick black line) then do as follows: Put AL
and G1 back to their original positions. Then
disconnect AR. Connect a new loop wire to
AR. Connect the other end of this new loop
wire at the middle of the suspected wire
section.
AR
If the indicator lamp now is green, then the
break is somewhere in the wire between the
disconnected end to the point where the
new wire is connected (thick black line
below). In that case, move the connection
for the new wire closer to the disconnected
end (roughly at the middle of the suspected
wire section) and check again if the indicator
lamp is green.
48 - Troubleshooting
Continue until only a very short section of
the wire remains which is the difference
between a solid green light and a flashing
blue light. Then follow instruction in step 5
below.
4. If indicator lamp still flashes blue in step 3
above: Put AL and G1 back in their original
positions. Then switch AR and G1. If
indicator lamp now is lit with a solid green
light then disconnect AL and connect a new
boundary wire to AL. Connect the other end
of this new wire at the middle of the
suspected wire section. Follow the same
approach as in 3a) and 3b) above.
5. When the break is found, the damaged
section must be replaced with a new wire.
Always use original couplers.
