The signal generated by the T 4000 is present at all points around the circuit The T 4000 connected to a 110V outlet via the C2901 cord set will cause an incoming signal on the neutral wire as well as an outgoing signal on the hot wire The close proximity of these two wires may cause the signals to cancel each other making it difficult to trace the cable in these areas In this case keep the R 4000 in the high sensitivity range Refer to Figure 11 Fig 11 E EH s 1 ke E E ripmpug j J To TrancSormer T 4000 At the panel breakers the hot wire is separated from the neutral wire where it is grounded allowing easy circuit breaker identification In that case use the Low sensi tivity range of the R 4000 So if tracing the branch wiring through the walls is not nec essary use the C2901 for quicker connection Refer to Figure 12 Fig 12 R 4000 Signals Cancel C2901 Cord Sel 10 Easy tracing of wires and buried cable is accomplished by simply separating wire from the return path roundi Instead of using the neutral wire or the conduit as the ground use the C2902 Alligator Clip cord set and attach the grounding test lead to a separate ground such as a water pipe Refer to Figure 13 Fig 13 Tracing Buried Cables T 4000 4 Tracing Buried Cables 4 11 Using the A2202 Clamp On Transmitter Accessory The A2202 will allow non contact signal indication onto energized or non energized
3. This signal can be detected back to the main generator However the signal will not interfere with any sensitive electronic equipment and does not require power interruption The unit is intrinsically safe and has a LOW signal transmission set ting that must be used when tracing GFCI protected circuits When connecting to a circuit as a load the signal will be present anywhere between the T 4000 and the power source Line side or Upstream no signal will be present on wiring on the other side of the transmitter load side or downstream For example a transmitter connected to a circuit breaker will produce no signal on that circuit It will however cause a signal to be generated between that panel and the transformer and beyond When connecting to an unenergized circuit the live indication on the display will remain OFF When the user starts the transmission the transmitter injects a combina tion of signals onto the conductor The signal will travel along the conductor until it ends There is no difference in the functional mode of the unit when tracing energized circuit and unenergized circuits On an open line no current will flow so the injected signal will present itself as a voltage spike along the wire which is detected by the R 4000 in the OPEN mode When the conductor is part of a complete circuit the voltage causes a current to flow which produces a signal that is detected in the SHORT mode The T 4000 contains
4. 14 Tracing Wires in Conduit When seeking a ground fault within metal conduit the ground is the conduit Connect one of the clips to the conduit to complete the circuit Steel conduit will tend to attenuate the signal strength so tracing will require higher sensi tivity levels and access to within a few feet of the conduit Aluminum conduit will severely attenuate the signal and sometimes even blocking all the signal from the wire It may be necessary to periodically access the wire in the conduit to confirm signal presence Locating Circuit Breakers Or Fuses Caution Always check to make sure the line voltage DOES NOT EXCEED the range of the T 4000 9 600V 1 Connect the T 4000 to the circuit as shown in Fig 17 using either the C2901 pigtail Cord set for 110V receptacles or the C2902 Alligator Clip cord set 2 Turn ON the unit 3 Select a signal level by pressing on Signal Level push button 4 Turn ON the R 4000 receiver 5 Select the Short Range and Low sensitivity 6 Move the Receiver in front of the outside of each circuit breaker as shown to determine which one has the strongest signal 7 If two or more breakers produce the same signal strength indication Move the receiver away slowly from each of them and watch the indication level Refer to Figure 17 Fig 17 Identifying Circuit Breakers Tracing Energized Wires 1 Connect the Alligator Clip Cord set to the T 4000 2 Make sure the voltage

H mode only Remove the battery booster to return to normal operation Fig 15 Tracing Open Wire g g Up t Finding Ground Faults A ground fault is a direct connection of the conductor to ground A typical ground fault may cause a tripped circuit breaker or a blown fuse in contrast to an open which passes no current In this situation the B2024 battery can be used as the current source The high voltage from the B2024 will overcome a high resistance fault and will produce a stronger signal Also you can use line voltage as the power source by connecting the T 4000 across the breaker Note When using the battery booster B2024 or B2025 the unit will work in ultra high 7 mode only Remove the bat tery booster to return to normal operation 1 Plug the alligator clip cord set into the T 4000 2 Attach one clip to the faulted wire and the other one to ground 3 Press the signal level push button and select the appropriate level 4 If possible ground all adjacent conductors 5 The R 4000 receiver can then be used to trace the wire The signal should remain relatively constant until you pass the ground fault At the fault the signal from the T 4000 will pass from the wire and disperse into the ground For this reason the signal strength will decrease gradually Watch the LEDs carefully in order to locate the fault within a few inches Refer to Figure16 Fig 16 Finding Ground Faults T 4000

ON by pressing the ON OFF push button and select a signal level transmission by pressing the signal level push button 6 Tum the R 4000 ON by pressing the ON OFF push button 7 Select OPEN mode by pressing the MODE push button the LED must be ON Note If the conductor is buried in moist soil the SHORT mode may give better results 8 o i HIGH sensitivity by pressing the SENSITIVITY push button the LED must e ON 9 Starting from the T 4000 trace the conductor The open will be at the point you begin to lose signal At that point select the MID sensitivity mode the LED must be blinking in order to pinpoint the exact location of the Open 10 Repeat process from the other end of the wire to make sure that you trace the right wire If you end up tracing the entire length of the wire without locating the open you may experiencing capacitive coupling or Signal bleed off onto the adjacent conductors This condition may be alleviated by a grounding all adjacent conductors b minimizing the distance between the point of connection and the open If another conductor is connected to the first conductor somewhere along its length the Signal will split between them causing both conductors to emit half the signal each The B2024 battery or the B2025 converter can be used to increase the signal strength Note When using the battery booster B2024 or B2025 the unit will work in ultra high U
7. conductors On energized lines the signal will propagate downstream to the end of the circuit provided there is a current flowing in the circuit Unenergized lines must be grounded at both ends or made into a complete circuit The signal strength can be boosted significantly by using the B2024 battery Pack Note When using the battery booster B2024 or B2025 the unit will work in ultra high U H mode only Remove the battery booster to return to normal operation One typical application for the A2202 is to access the hot wire at the panel in order to identify the downstream loads 1 Plug A2202 into T 4000 Set signal level to High 2 Clamp the A2202 around the hot wire 3 Set the R 4000 to OPEN mode and trace the downstream wiring To trace buried lines switch to SHORT mode See Locating Outlets From The Breakers Panel on page 17 Fig 14 A2202 Clamp On Transmitter Accessory 12 Finding Opens Opens are dead end conductors that are not connected to anything and therefore do not pass current To find an Open use the T 4000 transmitter R 4000 receiver and the alligator clip cord set Refer to figure 15 1 Plug the two banana plugs into the T 4000 2 Connect one of the alligator clips or the grounding test lead to a separate ground 3 Connect the other alligator clip to the conductor 4 Where possible ground any other conductors sharing the same path as the Open wire 5 Turn the T 4000
