1. PRECAUTIONS AND SAFETY MEASURES6

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 Sensor

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 Sensor

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 Sensor

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

mode 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.

The AT-8000-T Transmitter works on Energized and De-energized circuits up to 600 V AC/DC in Category I through Category IV electrical environments. Figure 2.3: Overview of AT-8000-T Transmitter AT-8000-T TRANSMITTER

2. Off: De-energized

RUBBER OVERMOLDED ENCLOSURE VOLUME ADJUSTMENT BUTTON (+/-) ON/OFF: Short press to turn the Transmitter on. Long press >2s to turn the Transmitter off. Volume adjustment: The volume can be changed by short presses on VOLUME UP/DOWN buttons. In addition to mute, four volume levels are available. The chosen volume level will be shown on LED display for a short time. If sound is muted, the MUTE LED light will be on. The sound pattern is different depending on chosen operating mode. Voltage Warning indicator: The warning light will be ON for Energized circuits (30 to 600 V AC/DC), OFF for De-energized circuits (0 to 30 V AC/DC), and BLINKING if an overvoltage is detected (> 650 V AC/DC). TRANSMISSION MODE INDICATOR: The LEDs will blink with different rhythm depending on the chosen operating mode. Transmitting in HIGH mode – Fast blinking Transmitting in LOW mode – Slow blinking Transmitting in LOOP mode – Alternating blinking High mode: Short press on HI to turn on HIGH transmitting mode. Second short press on HI button to turn off transmitting. Low mode: Short press on LO to turn on LOW transmitting mode. Second short press on LO button to turn off transmitting. Loop mode: Long press (>2s) on HI to turn on Loop mode. Short or long press on HI button to turn off Loop mode.9

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. Figure 2.2a: Generating a signal with HIGH and LOW modes and closed loop

TIP SENSOR Loop mode generates a signal (current flow) in closed loop De-energized circuits only. Loop mode is used to pinpoint the location of a short (because the current will not be able to flow in open branches) and to trace wires that are grounded on the far end (because the loop is closed via ground connection). Figure 2.2b: Generating a signal in Loop mode

TIP SENSOR 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.10

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.11

(included with AT-8030, optional for AT-8020) The Signal Clamp accessory is used for applications when where is no access to the bare conductors. The clamp attachment enables the Transmitter to induce a signal through the insulation into either wires. The clamp works on low impedance closed circuits.

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. 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.

3.1 Tracing Energized Wires

Connecting Transmitter test leads

1. Connect the green and red test leads to the

Transmitter (polarity does not matter).

2. Using provided test leads accessories, connect

the green wire to a separate ground (metal building structure, metal water pipe, or ground wire on a separate 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”

for alternative tracing methods. Figure 3.1a: Proper connection with separate ground AT-8000-T TIP: The Transmitter, with the red test lead, can be directly connected to the live wire of the working electrical equipment under load (motor, electronics, etc). Tracing can be performed without needing to turn off the equipment or switching power off. AT-8000-T Figure 3.1b: Transmitter set up Set up the AT-8000-T Transmitter

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

on for circuits with voltage above 30 V AC/DC. Note: Make sure to use the separate neutral connection as described above.

3. Select HIGH signal mode by pressing HI for most applications. The Transmitter will appear

as shown in Figure 3.1c. The LED display will quickly begin to blink. SMART SENSOR TM14

3. MAIN APPLICATIONS - SMART SENSOR

(Energized) 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 Energized SMART SENSOR

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 Sensor

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 SENSOR

mode by using the directional arrows and pressing the yellow ENTER button.

3. Hold the Receiver with the Smart Sensor

facing the target area. If the screen flashes a “?” in 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 Sensor

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 Sensor

2. Select 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 3.1g). 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.

5. Receiver Positioning: For best results, align groove on Tip Sensor with wire direction.

Signal may be lost if not properly aligned (Figure 3.1h).

6. To verify wire direction, periodically rotate the Receiver 90 degrees. Signal strength will

be highest when wire is aligned with Tip Sensor groove (Figure 3.1i).

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

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. Figure 3.1g: Receiver screen showing signal detected in Energized TIP SENSOR mode 30-600V AC/DC40-400 HZTIP SENSOR ENERGIZED

Transmitter (polarity does not matter).

2. Using provided test leads, connect the green

wire to a separate ground (metal building structure, metal water pipe, or ground wire on a separate circuit) (Figure 3.2a).

3. Connect the red test lead to the wire being

traced. For receptacles, make sure to connect the test lead to the line (hot De-energized) wire. For De-energized systems the signal will be transmitted across all branches of the circuit. Figure 3.2a: Proper connection with separate ground AT-8000-T Set up the AT-8000-T Transmitter

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. AT-8000-T TRANSMITTER

3. MAIN APPLICATIONS - TIP SENSOR (De-Energized)

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.

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

SIGNAL Figure 3.2c: Receiver showing signal detected in De-energized TIP SENSOR 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. TIP SENSOR18

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. AT-8000-T Set up the AT-8000-T Transmitter

1. Press the power button to turn on the Transmitter.

2. Verify that the test leads are properly connected. The red LED voltage status light will

illuminate for Energized circuits with a voltage above 30 V AC/DC. If the voltage is De-energized, the light will be off.

3. Select the HIGH signal mode for breaker/fuse locating.

3. MAIN APPLICATIONS - BREAKERS (Energized and De-Energized)

Energized and De-energized breaker/fuse locating BREAKERS

Receiver Process Overview Tracing breakers/fuses is a two-step process:

SCAN - Scan each breaker/fuse for one second. The Receiver will record tracing signal levels.

LOCATE - The Receiver will indicate the single breaker/fuse with the strongest recorded signal. 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 either Energized BREAKERS mode or De-Energized BREAKERS mode by using the

directional arrows and pressing the yellow ENTER button. Step 1 -

2. Scan each breaker/fuse for a second by touching it with the Tip Sensor. Make sure the

groove on the Tip Sensor is parallel to the breaker/fuse lengthwise (Figure 3.3e).

3. To assure sufficient time between the scans, wait for active green arrow and audible

alert (2 beeps) before moving to the next breaker/fuse.

4. Scan all breakers/fuses – the order of scanning does not matter. You can scan each

breakers/fuses multiple times. The Receiver records the highest detected signal. Usage tip: For best results try to scan at the output of the breaker/fuse. Important note: Differentiation in breaker/fuse designs, height, internal contact structure may affect precision of breaker/fuse identification. For most reliable results, remove the breaker/ fuse panel cover and perform scan on the wires instead of breakers/fuses. Scan the breakers/ fuses always at the same position and alignment of the Tip Sensor. A variation may affect improper results.

3. MAIN APPLICATIONS - BREAKERS (Energized)

1. Select LOCATE mode by using the directional

arrows and pressing the yellow ENTER button (Figure 3.3d).

2. Rescan each breaker/fuse by touching each

with the Tip Sensor for a second. Active red arrow indicates scanning process. Make sure the groove on the Tip Sensor is parallel to the breaker/fuse lengthwise (Figure 3.3e). Usage Tip: Hold receiver in the same position as during scanning step

3. Rescan all breakers/fuses until solid green arrow

and audible alert indicates that the correct breaker/ fuse was found (Figure 3.3f).

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

Figure 3.3d: LOCATE mode – Searching for correct breakers/fuses Usage Tip: The accuracy of breaker/fuse identification results can be verified by switching the Receiver to Energized or De-Energized TIP SENSOR mode and checking that that the signal level of the breaker identified by the Receiver is the highest among all breakers/fuses. Figure 3.3f: LOCATE mode – breaker/fuse identified

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. For precise pinpointing of line/phase wire versus neutral wire, increase or decrease

sensitivity by pressing + or – on the keypad.

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

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

, TIP SENSOR or BREAKER. Method 2 – Do NOT use separate ground to avoid tripping GFCI: (for GFCI-protected outlets and breakers)

• 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).22

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.

TIP SENSOR Figure 4.2: Locating the place of the fault

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.24

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

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

TIP SENSOR Figure 4.6a: Tracing a shielded wire If shielded wire is disconnected from ground at the far-end:

1. Setup the Transmitter in Wire Tracing mode (see section 3.2).

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 a wire tracing mode to trace the shield as described in section 3.2.

TIP SENSOR Figure 4.6b: Tracing a shielded wire disconnected from ground at the far-end25

The AT-8000 can trace wires underground, the same way it can locate wires behind walls or floors. Perform tracing as described in Energized SMART SENSOR

mode or Energized / De-Energized TIP SENSOR modes. You can use a hot sick attachment to make tracing more ergonomic and convenient.

TIP SENSOR Figure 4.7: Tracing underground wires

4.8 Tracing Low Voltage Wires and Data Cables

The AT-8000 can trace data, audio, and thermostat cables (to trace shielded data cables, refer to section 4.6). Trace data, audio, and thermostat cables:

1. Connect the Transmitter using the separate ground method described in section 3.2.

2. Set the Receiver to De-energized TIP SENSOR mode and trace the wire.26

connecting to energized wire, make sure the Transmitter is connected on the load side.

2. Select respectively Energized or De-energized TIP SENSOR mode on the Receiver. Pull

one wire out as far as possible from other wires in the bundle and touch it with the Tip Sensor. The strongest signal indicates the proper wire in the bundle. Note: In some special cases it may be necessary to connect all unused wires on the Transmitter side to ground.

4.10 Mapping a Circuit using Test Leads Connection

Mapping a circuit can be only performed on a De-energized circuit when using test leads connection.

1. Switch the breaker/fuse to the OFF position.

2. Set up the Transmitter and Receiver as described in the De-energized Wire Tracing as

described in section 3.2.

3. Scan face plates of receptacles and wires towards load with the Tip Sensor of the Receiver

4. All the wires, receptacles and loads that have a strong signal as indicated by the

Receiver are connected to this breaker/fuse. AT-8000-T Figure 4.10: Mapping a circuit

4.11 Tracing Breakers/Fuses on Systems with Light Dimmers

Light dimmers can produce a significant amount of electrical “noise” that consists of multi- frequency signals. In some rare situations, the Receiver can misread this noise, often called a “ghost” signal, as a Transmitter - generated signal. Therefore, the Receiver may provide misleading readings. When locating breakers or fuses on systems with light dimmers, the dimmer should be off (the light switch is off). This prevents the Receiver from indicating a wrong breaker/fuse.28

4. SPECIAL APPLICATIONS

4.12 Signal Clamp - Closed Loop Circuits

Closed loop, De-energized and low impedance circuits The clamp accessory is used for applications where there is no access to a bare conductor to connect the test leads. When the clamp is connected to the Transmitter, it enables the Transmitter to induce a signal to the Energized or De-energized wire through the insulation. Typical applications of the Signal Clamp include tracing conduits or shields grounded on both ends. For signal cables and De-energized wires or loads, temporarily ground the circuit on both ends to perform tracing. Connecting the Signal Clamp

1. Connect the CT-400 test leads to the terminals of the Transmitter (polarity does not matter).

2. Clamp the CT-400 Signal Clamp around the conductor. To increase the signal strength,

wind a few turns of the conductor wire around the clamp if possible. AT-8000-T Figure 4.12a: Signal Clamp connection Set up the AT-8000-T Transmitter

1. Press the power button to turn on the

Transmitter. The red LED voltage status indicator should be OFF when the clamp is connected and when working with either Energized or De-energized systems.

2. Press HIGH signal mode and hold button for

>2 seconds to select the Loop mode on the Transmitter. This clamp mode (loop mode) generates a boosted 6 kHz signal in order to provide superior tracing results. AT-8000-T TRANSMITTER

2. Select 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. While tracing, periodically

adjust sensitivity to keep signal strength near 75. Increase or decrease sensitivity by pressing + or – on the keypad.

5. Receiver Positioning: For best results, align groove on Tip Sensor with wire direction as

shown. Signal may be lost if not properly aligned.

6. To verify wire direction, periodically rotate Receiver 90 degrees. Signal strength will be

highest when wire is aligned with Tip Sensor groove.

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