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
above 30V AC/DC.
IMPORTANT!
The Voltage Warning Indicator light will blink when overvoltage (>650V AC/DC) is detected.
In case of overvoltage immediately disconnect Transmitter from the circuit!
This Voltage Waning Indicator is not desinged to check for absence of voltage. Please use a
voltage tester therefore.
If High (Hi) or Low (Lo) Signal button is pressed momentarily, the transmitter starts
generating a tracing signal. Based on detected voltage, the transmitter automatically
switches to either:
• Energized mode (30 to 600V AC/DC) generating 6kHZ frequency or
• De-energized mode (0 to 30V AC/DC) generating 33kHz frequency
The Energized Mode uses a lower transmission frequency (6kHz) than de-energized mode
(33 kHz) to reduce signal coupling between wires. De-energized mode requires higher
frequency (33 kHz) 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
AT-6000-TE, 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, since the signal is injected, it will travel through all the circuit branches.
It is a high frequency, very low energy signal that will not harm any sensitive equipment.
