At the ends of the target cables opposite the Remotes, connect
the
WireMaster Mapper
, in succession, to each cable, noting the
ID number of the LED that lights.
If upon connecting the
WireMaster Mapper
to a cable, the OPEN
LED remains lit, the cable may not have a Remote at its opposite
end, an open fault may be present in the cable, or a splitter or
some other device may be present in the cable. The
WireMaster
Mapper
will not work through splitters, amplifiers, or any other
DC blocking devices.
If the SHORT / CONTINUITY LED lights and the beeper sounds,
the cable may be shorted, or some device is connected to the
cable that appears as a short to the
WireMaster Mapper.
If the OVERLOAD / VOLTAGE LED lights and the beeper sounds,
at any time, the cable being tested has voltage on it and cannot be
ID’ed.
If a number of ID LEDs light simultaneously, a stray voltage may
be present that will prevent the cable from being ID’ed.
Most non-faulted cables containing 2 conductors or more can be
mapped. Even single conductors can be mapped if a low resis-
tance ground or return path is available.
