2.1 AT-6010-R Receiver

The AT-6010-R Receiver detects the signal in wires and cables. The signal is generated by the AT-

6010-T Transmitter, which is connected to the wire.

The main advantage of this method is the ability to trace the path of the particular wire using

the Receiver. Since the signal is not present in any neighboring wires, the Receiver will

detect only the wire that is connected to the Transmitter.

Note: The Receiver will NOT detect signals from a wire through metal conduit or shielded cable. Refer

to Special Applications, section 4.4 “Tracing Wires In Metal Conduit” for alternative tracing methods.

2.2 AT-6010-T Transmitter

The AT-6010-T Transmitter works on Energized and De-energized circuits up to 600 V AC/DC in

Category I through Category III electrical environments.

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 location. This function will be used

majority of the time.

Loop mode – This mode is initiated by short pressing On/Off button. Loop LED is On when this

mode is activated. 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 setting when using test leads?

HIGH mode (Hi) generates a signal in all open branches of the De-energized circuit. This is useful

when tracing open wires. Hi mode will NOT work on wires that are grounded on the far-end

because the signal cannot be generated.

Figure 2.2a: Generating a signal with HIGH mode

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).

2. KIT COMPONENTS

7

Figure 2.2b: Generating a signal in Loop mode

Note: Loop mode only works on De-energized circuits. It is automatically disabled when the

Transmitter is connected to an Energized line with test leads.

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 designed to check for absence of voltage. Please use a

voltage tester instead.

The Transmitter starts generating a tracing signal as soon as it is turned on. 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.

2. KIT COMPONENTS

8

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 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.

X� 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. MAIN APPLICATIONS

11

3.1 Tracing – Energized and De-energized Wires

Connecting test leads to the Transmitter

1. Connect the green and red test leads to the

Transmitter (polarity does not matter).

2. Using provided test leads accessories, connect the

red test lead to the wire being traced, Energized or

De-energized. For receptacles, make sure to connect

the test lead to the line (hot) wire. 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).

3. Connect the green wire to a separate ground

(metal building structure, metal water pipe, or

ground wire on a separate circuit).

*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.

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.

Figure 3.1b: Connecting Transmitter to Energized working system

Setting up the AT-6010-T Transmitter

1. Press ON/OFF key 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, and it 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. HIGH signal mode is automatically activated when the

Transmitter is turned on. The LED on the Transmitter

should appear as in Figure 3.1c.

Using the AT-6010-R Receiver in Tracing Mode

Use Receiver to precisely pinpoint the wire location or the place of the fault. The Receiver will

indicate detected signal strength using a two digit readout, bar graph and sound.

1. Turn the Receiver on. Tracing mode is automatically activated.

2. Scan target area with the Tip Sensor to ﬁnd the highest signal level. While tracing,

periodically adjust sensitivity to keep the signal strength near 50. Increase or decrease

sensitivity by pressing + or - on the keypad.

3. For best results while tracing Energized wires, align groove on the Tip Sensor with wire

direction as shown in Figure 3.1d. Signal may be not detected if not properly aligned. To

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

highest when wire is aligned with the Tip Sensor groove.

Depending on the detected signal, the Receiver automatically switches to either Energized

or

De-energized mode, and displays this information on the LCD. No manual setup is necessary.

Note: For best results, keep the Receiver at least 3 feet from the Transmitter and test leads to

minimize signal interference.

3. MAIN APPLICATIONS - TRACING ENERGIZED AND DE-ENERGIZED WIRES

13

3.2 Identifying Breakers and Fuses (Energized and De-energized)

Note: For breaker locating, a simpliﬁed direct connection to hot and neutral wires can be used

because these wires are separated at the breaker 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 (section 3.1) 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.

Figure 3.2b: Separate ground connection

(Preferred)

Figure 3.2a: Simpliﬁed direct connection

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, connect the red lead to the line (hot) wire on the load side of the

system. The wire can be energized or de-energized. Connect the green lead to a separate ground,

such as a metal building structure, metal water pipe, or ground wire on a separate circuit.

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.

Figure 3.2c: Connecting Transmitter to Energized working system

Setting up the AT-6010-T Transmitter

1. Press the ON/OFF key 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. HIGH signal mode is automatically activated when Transmitter is turned on.

Using the AT-6010-R Receiver

1. Turn the Receiver on. Tracing mode is automatically activated.

2. Align the groove on the Tip Sensor with the breaker lengthwise (See Figure 3.2d).

3. Scan all breakers in any order to ﬁnd a breaker with the highest signal. Adjust sensitivity by

pressing + or - on the keypad to show the signal strength near 50 for the breaker with the

highest signal. After any sensitivity adjustment rescan all breakers to ﬁnd the one with the

highest signal level.

Important note: Differentiation in breaker designs, height and internal contact structure may

affect the precision of breaker identiﬁcation. For most reliable results, remove the breaker panel

cover and perform a scan on the wires instead of the breakers.

Depending on the detected signal, the Receiver automatically switches to either Energized

or

De-energized mode, and displays this information on the LCD

.

4.1 GFCI-Protected Circuit Wire Tracing: Connecting the AT-6010-T Transmitter to GFCI

Protected Circuits

Connecting the Transmitter to an Energized GFCI protected circuit using a separate ground

method will trip the GFCI protection. Use the following methods to work with GFCI protected

circuits. For a De-energized GFCI-protected outlet that is not tripped, you can connect test leads

directly to the outlet contacts using the 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 to connect the Energized hot

wire to the receptacle.

• Connect the green test lead using a separate ground method.

• Perform tracing as described in sections 3.1 or 3.2.

Method 2 – Do NOT use separate ground to avoid tripping GFCI:

(for GFCI-protected outlets and breakers)

• Connect the Transmitter with the test leads to the Neutral and Hot wires.

• Perform tracing as described in sections 3.1 or 3.2.

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)

• Connect the Transmitter directly to the wire as described in section 3.1.

• Perform tracing as described in sections 3.1 or 3.2.

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 3.1 to connect the Transmitter and perform tracing.

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

Figure 4.2: Locating a break or open

4. SPECIAL APPLICATIONS

16

4. SPECIAL APPLICATIONS

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 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.

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

2. Switch the Transmitter to Loop mode by short press of On/Off button. Verify that the Loop LED is ON.

3. Turn on the Receiver. Tracing mode is automatically activated.

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.

Figure 4.3: Tracing a cable to ﬁnd shorts

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

4.4 Tracing Wires in Metal Conduit

The Receiver is unable to pick up the signal from a wire through a metal conduit. The metal

conduit will completely shield the tracing signal.

Note: The Receiver will be able to detect wires in a non-metallic conduit. For these applications

follow general tracing guidelines.

To trace wires in a metal conduit:

1. Turn on the Receiver. Tracing mode is automatically activated.

2. Open junction boxes and use the Receiver 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 a signal directly to the conduit will send the signal through all the conduit

branches, making tracing a particular conduit path impossible.
