3.3 Tracing De-energized Wires

TIP SENSOR
De-energized TIP SENSOR mode is used for general
wire tracing, pinpointing wires in bundles, tracing
in tight corners and confined spaces such as
junction boxes or inside enclosures.
Connecting transmitter test leads
1. Connect green and red test leads to the
transmitter (polarity does not matter)
2. Connect red lead to de-energized Line wire
(on the load side of the system).
In de-energized mode the signal will be
injected to ALL branches of the circuit, not
just between the outlet and the breaker as in
energized modes.
3. Connect green lead to a separate ground
(metal building structure, metal water pipe,
or ground wire / Protective Ground (PE) on a
separate circuit).
ATTENTION: Due to safety reasons this is only
allowed in de-energized circuits. (see figure
3.3a) Do not use a ground wire that runs in
parallel to the wire you are going to trace, as
it will reduce or cancel tracing signal.
NOTE:If circuit is energized you will trip RCD.
Set up the AT-7000-TE Transmitter:
1. Press ON/OFF key to turn on the transmitter.
2. The red LED voltage status indicator should be off, indicating that the circuit is de-
energized. If LED is on, disconnect power to the circuit.
3. Select HIGH signal mode for most applications. Screen will appear as shown in Figure 3.3b
Note: The LOW signal mode can be used to limit the signal level generated by the
transmitter in order to more precisely pinpoint wire location. A lower signal level reduces
coupling to neighboring wires and metal objects and helps to avoid misreading due to
ghost signals. A lower signal also helps to prevent oversaturating the receiver with a
strong signal that covers a large area. The LOW signal mode function is rarely used, only for
most demanding precise wire tracing applications.
