Ground Fault Locator
Operating Instructions
Warning –Read the entire instruction booklet before operation.
Failure to do so could result in injury or death.

Product Description
The GFL 6000 is designed to locate cable faults that result in an
electrical path to ground. This is accomplished by the unit detecting
the ground radiant bleed out that is produced from the faulted cable.
You will need a separate cable locator to locate the path of the entire
cable for correct operation.
The GFL 6000 comes with:
-GFL 6000 A-frame
-GFL 6000 Receiver
-GFL 6000 dual power transmitter
(rechargeable battery included)
-Ground Stake
-Wall charger
-Operating Manual

Unit Overview
The GFL 6000 Transmits a voltage charge repeatedly every 4-5
seconds. The charge is transmitted to the faulted cable through the
output leads. Once the voltage charge reaches the fault in the cable, a
portion of the electrical current will leak out to the earth ground
surrounding the cable. The amount of current leaked to ground will
depend on resistance of the fault and path to the ground stake vs the
other available paths for the current to flow.
The A-frame (with receiver mounted to it) is then inserted into
the ground along the path of the cable. As the voltage charges is
pulsed down the cable, some of the current will leak out in to ground
and travel back to the ground stake. As it does so, some of the
current will travel up the A-frame to the receiver and cause the
needle on the receiver to kick in the direction of the fault. The needle
with bounce back and forth after a current spike is detected so only
the initial kick will indicate the direction of the fault.
The receiver determines which probe on the A-frame receives
the current first and cause the initial movement of the needle to kick
in the direction of the fault.
The Transmitter is powered by an internal 12v rechargeable
SLA battery. The battery is charged with a 110VAC wall adapter that is
provided with the unit. To recharge the battery just simply plug the
wall adapter into any 110v AC wall socket and then insert the other
end into the 5.5mm charging socket located next to the power switch
on the front of the unit.
The receiver is powered by 1 9v battery (included). The
battery is changed by removing the 4 outside screws on the back of
the receiver. The old battery can then be easily removed and a new
one installed.

Operation Instructions
1. Ensure that the cable that is to be tested is free from any
power and then isolate it by disconnecting it at both ends.
2. Assemble the A-frame and receiver by sliding the bracket
attached to the bottom of the receiver into the bracket
located on the top of the A-frame and then lock into place.
3. With the transmitter off, connect the black output lead to
the provided ground stake and then insert the stake into
the ground as far as possible.
4. With the transmitter off, connect the red output lead to
the cable to be tested.
5. Once the transmitter is correctly connected and ensuring
that no on is touching the cable, select the voltage to be
applied by switching the output rocker switch to either
4800 volts or 6400 volts. Once the desired voltage is
selected lift the red toggle switch guard up and flip the
toggle switch to the on position. A green light should come
on indicating the presence of high voltage and machine
operation. The speaker should then beep every time the
transmitter pulses (about every 4-5 seconds). Do not
touch any component, cable, or stake while the
Transmitter is operating.
6. Turn the receiver on and place the A-frame probes in the
ground parallel to the path of the cable. Insert the probes
into the ground adequately to ensure proper signal
reception. When one of the probes on the A-frame
receives a signal, the needle will then kick in the direction
of the fault. Remember that only the initial kick of the
needle is important.
7. Continue to move the A-frame along the cable path
following the initial needle kicks of the receiver.

Comments/Notes

Warranty - Innovative Utility Products offers a 12-month warranty
on all manufacture defects from the manufacture date on the unit.
IUP will replace or repair any unit within a 12-month period unless it
has shown signs of abuse or misuse. The unit must be returned to
Innovative Utility Products for evaluation before any warranty
repairs will be considered
8. Once you pass the fault in the cable the initial kick of the
meter will kick in the reverse direction indicating that you
have passed the fault. This indicates that the fault is
between the last 2 A-frame insertion points.
9. Continue moving the A-frame along the path in the
direction of the initial kick. Once the A-frame is located
directly over the fault the needle should cease to move.
Verify this by moving the A-frame in a circle shape around
the fault watching the initial kick of the needle to verify
the location of the fault. Mark the spot for repair.
10. Before repair, turn the transmitter off and disconnect it
from the cable. Never touch the transmitter, leads,
ground stake, or cable while the transmitter is turned on.

Tips:
If there is more than one fault in the cable there could be
some confusion as all faults will result in needle kicks in their
direction. The sensitivity can be adjusted to look for weaker or
stronger signals that can indicate different faults.
It is possible for the needle to kick toward the transmitter if
the A-frame is placed too close to it. Continue to move down the
cable to gain access to signals from fault. It is also possible for the
needle kicks to cease between the transmitter and the fault. If this
happens, continue to move along the cable and the meter will begin
moving again when signal is received.
If the A-frame cannot be inserted in the ground (concrete or
asphalt) try using wet sponges. This can increase the conductivity of
the A-frame.
