Setup
CAUTION: The transmitter can produce hazardous voltages. Turn the
transmitter OFF before handling the output leads. Disconnect all wires from
the irrigation controller when fault finding.
Before starting you must ensure that the transmitter is set up properly.
IMPORTANT: To ensure that the transmitter is producing optimum signal,
check that the low battery symbol is not visible. Range may be impaired if
signal is low.
IMPORTANT SAFETY INFORMATION
Electric shock hazard:
• Do not connect the transmitter to any active circuits.
• Live circuits can present a hazards to the user and equipment.
• Tracing signal may present a hazard to connected devices. Disconnect all
electronic devices where possible.
Failure to observe these precautions may result in injury and can damage the
instrument or connected equipment.
Where possible ground the far end
of the cable to be found. You will
need to use higher output levels if
this cannot be achieved.
With the transmitter OFF, connect
the red lead to the wire to be
located and the black lead to a
good earth ground using the stake
provided. Refer to figure 1.
If the clock/controller is indoors,
the earth ground stake should be
placed near the point where the
cables leave the building. It may
require temporarily running a
length of wire to the outside. Never
use a building ground such as a
water pipe or electrical ground.
Now activate the transmitter by pressing the power button for about
one second. Observe the transmitter current indicator and increase the
output level (up button), setting levels 1, 2, 3, 4 or 5 until the gauge reads
somewhere in the middle (approximately 30% to 70% of full scale). If 30%
is not obtainable, you may not have enough of a ground fault or leakage to
ground to locate the entire length of the wire (hence why grounding the far
end is advantageous if it can be done).
