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.

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).

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 T 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.
