2. KIT COMPONENTS

2.1 AT-8000-R Receiver

The AT-8000-R Receiver detects the signal generated by the AT-8000-T Transmitter along wires using either the Tip Sensor or Smart SensorTM and displays this information on the full color TFT LCD display.

Active tracing using a signal generated by the AT-8000-T Transmitter

The Smart SensorTM works with a 6 kHz signal generated along Energized wires (above 30 V AC/DC) and provides an indication of the wire position and direction relative to the Receiver. The Smart SensorTM is not designed to work on De-energized systems; for that application the Tip Sensor should be used in De-energized mode.

The Tip Sensor may be used on either Energized or De-energized wires and can be used for general tracing, tracing in tight spaces, locating breakers/fuses, pinpointing wires in bundles or in junction boxes. The TIP SENSOR mode will pinpoint the wire location with both an audible and visual indication of detected signal strength, but unlike SMART SENSOR it will not provide wire direction or orientation.

Note: The Receiver will NOT detect signals from the wire through metal conduit or shielded cable. Refer to Special Applications, section 4.4 “Tracing Wires In Metal Conduit” for alternative tracing methods.

2. KIT COMPONENTS

Transmitter signal modes:

High Signal (Hi) – The HIGH mode function is recommended for most wire tracing

applications on Energized and De-energized circuits including breaker/fuse location. This function will be used the majority of the time.

Low Signal (Lo) – The LOW mode function is only appropriate for the most demanding and precise wire tracing applications, as it limits the signal level generated by the Transmitter in order to pinpoint the wire location more precisely. A lower signal level reduces coupling to neighboring wires and metal objects, which avoids misreadings due to ghost signals. A lower signal also prevents oversaturating the Receiver with a strong signal that covers too large of an area.

Loop mode – This mode is initiated by pressing and holding the HI button for >2 seconds. It should be used when working with closed loop De-energized circuits, such as shorted wires, shielded cables or De-energized wires that are grounded on the far-end.

How is the Loop function different from the Hi or Lo settings when using test leads?

Both HIGH and LOW modes generate a signal in all open branches of the De-energized

circuit. This is useful when tracing open wires. Hi/Lo modes will NOT work on wires that are shorted (closed loop) or grounded on the far-end because the signal cannot be generated.

Note: Loop mode only works on De-energized circuits. However the receiver needs to be set to Energized sensor mode (the transmitter creates safe low voltage state). It is automatically disabled when the Transmitter is connected to an Energized line with test leads.

2. KIT COMPONENTS

Working with the Transmitter

When the Transmitter is on and connected to the circuit with test leads, it checks for voltage. A red Voltage Warning Indicator will light up if the Transmitter detects dangerous voltage levels above 30 V AC/DC.

IMPORTANT! The Voltage Warning Indicator light will blink when overvoltage (> 650 V AC/DC) is detected. In case of overvoltage immediately disconnect the Transmitter from the circuit.

This Voltage Waning Indicator is not desinged to check for absence of voltage. Please use a voltage tester therefore.

If the High (HI) or Low (LO) Signal button is pressed momentarily, the Transmitter starts generating a tracing signal. Based on the detected voltage, the Transmitter automatically switches to either:

• Energized mode (30 to 600 V AC/DC) generating 6 kHZ frequency

• De-energized mode (0 to 30 V AC/DC) generating 33 kHz frequency

Energized mode uses a lower transmission frequency (6 kHz) than De-energized mode (33 kHz) to reduce signal coupling between wires. De-energized mode requires a higher frequency in order to generate a reliable signal.

Energized mode: In Energized mode, the Transmitter draws a very low current from the Energized circuit and generates a 6 kHz signal. This is a very important feature of the Transmitter, since drawing current does not inject any signal that would harm sensitive equipment connected to the circuit. The signal is also generated in a direct path between the Transmitter and the power source, thus NOT placing a signal onto any branches enabling wiring tracing directly back to the breaker/fuse panel. Please note that due to this feature, the Transmitter has to be connected on the load side of the circuit.

De-energized mode: In De-energized mode, the Transmitter injects a 33 kHz signal onto the circuit. In this mode, the signal will travel though all the circuit branches because it is injected. The high frequency/low energy signal will not harm any sensitive equipment.

2.3 CT-400 Signal Clamp

(included with AT-8030, optional for AT-8020)

3. MAIN APPLICATIONS

� IMPORTANT NOTICE, PLEASE READ BEFORE STARTING TRACING

Avoiding signal cancellation problems with a separate ground connection

The signal generated by the Transmitter creates an electromagnetic ﬁeld around the wire. This ﬁeld is what is detectable by the Receiver. The clearer this signal, the easier it is to trace

the wire. If Transmitter is connected to two adjacent wires on the same circuit (for example, hot and

neutral wires on a Romax cable), the signal travels in one direction through the ﬁrst wire and then returns (in opposite direction) through the second. This causes the creation of two electromagnetic ﬁelds around each wire with opposite direction. These opposing ﬁelds will partially or completely cancel each other out, making wire tracing difﬁcult if not impossible.

AT-8000-T

To avoid the cancellation effect, a separate ground connection method should be used. The red test lead of the Transmitter should be connected to the hot wire of the circuit you wish to trace, and the green lead to a separate ground, such as water pipe, ground stake, metal grounded structure of the building, or outlet ground connection of an outlet on a different circuit. It is important to understand that an acceptable separate ground is NOT the grounding terminal of any receptacle on the same circuit as the wire you wish to trace. If hot wire is Energized and the Transmitter is properly connected to a separate ground, the red LED on the Transmitter will light up. The separate ground connection creates maximum signal strength because the electromagnetic ﬁeld created around the hot wire is not being cancelled by a signal on the return path ﬂowing along an adjacent wire (hot or neutral) in the opposite direction, but rather through the separate ground circuit.

3. Connect the red test lead to the line/phase wire being traced. For Energized systems the signal will ONLY be transmitted between the load-side to which the Transmitter is connected and the source of power (see Figure 3.1a)

*Note: Please note that if working with GFCI protected circuits, this method will trip the GFCI protection. Refer to Special Applications, section 4.1 “GFCI-Protected Circuit Wire Tracing”

Proper connection with separate ground

Using AT-8000-R Receiver in Energized SMART SENSORTM mode

The Smart SensorTM enables easier wire tracing by showing the direction and position of the wire and is the recommended method for tracing Energized wires.

Note: The Smart SensorTM does not work on de-energized circuits; Tip Sensor should be used instead.

Using AT-8000-R Receiver

1. Press power button to turn on the Receiver; home screen may take up to 30 seconds to load.

2. Select SMART SENSORTM mode by using the directional arrows and pressing the yellow ENTER button.

3. Hold the Receiver with the Smart Sensor a red target then either no signal is detected or the signal is not adequate enough to display direction. (Figure 3.1d). Move the Smart SensorTM closer to the target area until the signal is detected and you see a directional arrow. If no signal is detected increase the sensitivity using the “+” button on the Receiver.*

4. Move the Receiver in direction indicated by the arrow on the screen (Figure 3.1e).

5. A green target symbol indicates that the Receiver is directly over the wire (Figure 3.1f). If the Receiver does not lock on the wire, decrease sensitivity using the “-“ on the keypad or set the Transmitter to transmit at LOW level for precision tracing.

6. Press ENTER when complete to return to the home screen.

*Note: For best results, keep the Receiver at least 3 feet from the Transmitter and its test leads to minimize signal interference and improve wire tracing results. Select the “Long” Smart SensorTM Range in the Settings Menu if working with wires that are greater than 3 feet deep.

1. Press power button to turn on the Transmitter.

2. Verify that the test leads are properly connected; the red LED voltage status light should be off for De-energized circuits below 30 V AC/DC.

Note: Make sure to use the separate ground connection as described above.

3. Select HIGH signal mode by pressing HI for most applications. The Transmitter will appear as shown in Figure 3.2b. The LED display will quickly begin to blink.

Note: The LOW signal precision 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 too large an area. The LOW mode function is only used for the most demanding and precise wire tracing applications.

Using AT-8000-R Receiver in De-energized TIP SENSOR mode

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.

1. Press power button to turn on the Receiver; home screen may take up to 30 seconds to load.

2. Select De-Energized TIP SENSOR mode by using the directional arrows and pressing the yellow ENTER button.

3. Hold the Receiver with the Tip Sensor facing the target area.*

4. Scan target area with Tip Sensor to ﬁnd highest signal level (Figure 3.2c). While tracing, periodically adjust sensitivity to keep signal strength near 75. Increase or decrease sensitivity by pressing + or – on the keypad. If signal is too strong for precise locating, change transmitter to LOW mode.

*Note: For best results, keep the Receiver at least 3 feet (1 m) from the Transmitter and its test leads to minimize signal interference and improve wire tracing results.

De-energized mode uses a different antenna in the Tip Sensor than Energized mode. Speciﬁc alignment of the Tip Sensor groove to the wire is not required. De-energized wire tracing results are based only on how close the Tip Sensor is to the wire.

3.3 Identifying Breakers and Fuses

Breaker mode automatically adjusts the sensitivity of the Receiver. As a result, the Receiver will pinpoint and indicate just one correct breaker/fuse. This enhancement helps to remove signal strength analysis from the breaker/fuse identiﬁcation process that is typical for less

advanced wire tracers.

Note: For breaker/fuse locating, a simpliﬁed direct connection to hot and neutral wires can be used because these wires are separated at the breaker/fuse panel. There is no risk of signal cancellation effect if wires are at least a few inches away from each other. However, the separate ground connection (Figure 3.3b) should be used for superior results speciﬁcally if wires need to be traced in addition to breaker identiﬁcation.

The simpliﬁed direct connection to hot and neutral wire will NOT trip the GFCI circuit.

Connecting the test leads

1. Connect the Transmitter using either simpliﬁed direct connection or separate ground connection.

2. If the simpliﬁed direct connection method is used, connect the test leads directly to the hot and neutral wires. While locating a breaker, wires will not be traceable as the signals will cancel each other out.

3. For separate ground connection, ﬁrst connect the green lead to a separate ground, such as a metal building structure, metal water pipe, or ground wire on a separate circuit.

4. Connect the red lead to the Energized hot wire on the load side of the system. The signal will ONLY be transmitted between the outlet to which the Transmitter is connected and the source of power.

3.4 NCV Mode

The NCV (Non-Contact Voltage) mode is used to verify that a wire is Energized. This method does not require the use of the Transmitter. The Receiver will detect and trace an Energized cable if the voltage is between 90 V and 600 V AC and between 40 Hz and 400 Hz. No current ﬂow is necessary.

Note: For safety, before working with wires, always verify that they are De-energized with an additional voltage tester.

�The voltage indication in NCV mode is not sufﬁcient to assure safety. This function is

not suitable to test for absence of voltage. This always requires a two-pole voltage test.

NCV mode operation

1. Press power button to turn on the Receiver; home screen may take up to 30 seconds to load.

2. Press NCV button to select the Non-Contact Voltage mode.

3. Hold the Receiver with the Tip Sensor against the wire.

4.1 GFCI-Protected Circuit Wire Tracing

Connecting AT-8000-T Transmitter to GFCI protected circuits. Connecting the Transmitter to an Energized GFCI protected circuit using separate ground

method will trip the GFCI protection. Use following methods to work with GFCI protected circuits (for De-energized GFCI-protected outlet that is not tripped, you can connect test leads directly to the outlet contacts using De-energized TIP SENSOR mode)

Method 1 – Bypass the GFCI circuitry to avoid tripping GFCI:

(for Energized GFCI-protected outlets only)

• Remove the protective receptacle wall plate.

• Using the alligator clip attach the red test lead to the screw connecting the Energized hot wire to the receptacle.

• Connect the green test lead using separate ground method as described in Energized TIP SENSOR mode.

• Perform tracing as described in one of the Energized modes: SMART SENSOR SENSOR or BREAKER.

• Connect Transmitter test leads to Neutral and Hot wires.

• Perform tracing as described in one of the Energized modes: SMART SENSOR

, TIP

SENSOR or BREAKER.

Note: This type of connection causes signal coupling and reduces signal strength. If the signal is too weak or untraceable, use Method 3.

Method 3 - De-energize the circuit: (for GFCI-protected breakers)

• De-energize the circuit.

• Connect Transmitter directly to the wire as described in De-Energized TIP SENSOR mode.

• Perform tracing as described in the desired De-Energized mode (TIP SENSOR for wire tracing or BREAKER for breaker identiﬁcation).

4. SPECIAL APPLICATIONS

4.2 Finding Breaks/Opens

It is possible to pinpoint the exact location where a wire is broken, even if the wire is located behind walls, ﬂoors or ceilings.

1. Make sure that wire is De-energized.

2. Use the steps described in section 3.2 to connect the Transmitter and perform tracing with the Receiver set to De-energized TIP SENSOR mode.

3. For best results, ground all De-energized wires that run in parallel with the black test lead. (Figure 4.2).

The tracing signal generated by the Transmitter is conducted along the wire as long as there is continuity in the metal conductor. To ﬁnd a fault, trace the wire until the signal stops. To verify the fault’s location, move the Transmitter to the other end of the wire and repeat, tracing from the opposite end. If signal stops at the exact same location, the fault has been located.

Note: If the place of the fault is not found, the result may be a high resistance break (partially open circuit). Such a break would stop higher currents from ﬂowing but will conduct the tracing signal through the break. Such faults will not be detected until the wire is completely open.

4.3 Finding Shorts

Shorted wires will cause a breaker/fuse to trip. To correct this, disconnect the wires and make sure the ends of the wires on both sides of the cable are isolated from each other and other wires or loads and are De-energized.

1. Connect the Transmitter with the test leads to the circuit as shown in Figure 4.3.

2. Turn the Transmitter to Loop mode by pressing HIGH button for two seconds. Verify that the Loop LED is ON.

3. Set the Receiver to Energized TIP SENSOR mode (the Transmitter will generate safe low voltage tracing signal) and perform tracing.

Start tracing the cable until the signal stops. To verify the place of the fault, move the Transmitter to the other end of the wire and repeat tracing from the opposite end. If the signal stops at the exact same location the fault has been located.

Note: This method will be affected by signal cancellation effect. Expect a relatively weak signal.

4.4 Tracing Wires in Metal Conduit: Junction Box Method

The AT-8000-R Receiver will not be able to pick up the signal from the wire through the metal conduit. The metal conduit will completely shield the tracing signal.

Note: The Receiver will be able to detect wires in non-metallic conduit. For these applications follow general tracing guidelines.

In order to trace wires in conduit:

1. Use either Energized or De-energized TIP SENSOR mode as described in sections 3.1 and 3.2.

2. Open junction boxes and use the Receiver’s Tip Sensor to detect which wire in the junction box is carrying the signal.

3. Move from junction box to junction box to follow the path of the wire.

Note: Applying signal directly to the conduit will send signal through all the conduit branches making tracing of one particular conduit path not possible.

4.5 Tracing Non-Metallic Pipes and Conduits

The AT-8000 can indirectly trace plastic conduits and pipes using the following steps:

1. Insert conductive ﬁsh tape or wire inside the conduit.

2. Connect the Transmitter’s red test lead to the ﬁsh tape and the green ground wire to a separate ground as described in section 3.2.

3. Set the Receiver to De-energized TIP SENSOR mode to trace the conduit.

4. The Receiver will pick up the signal conducted by ﬁsh tape or wire through the conduit.

4. SPECIAL APPLICATIONS

4.6 Tracing Shielded Wires

Shielded wires prevent the Receiver from detecting a tracing signal when following the standard user instructions. To effectively trace shielded wire, follow these procedures.

If shielded wire is grounded at the far-end:

1. Setup Transmitter in Loop mode by pressing HIGH button for two seconds. Verify that the Loop LED is ON.

2. Disconnect the ground on the near-end of the shielded wire and connect the shield to one of the terminals of the Transmitter (polarity does not matter) with a test lead.

3. Connect the second output of the Transmitter to a separate ground.

4. Set the Receiver to De-energized TIP SENSOR mode to trace the shield as described in section 3.2.
