MPORTANT SAFETY NOTES
IMPORTANT! Please read the Operator's Manual thoroughly before operating the unit.
Having a complete understanding of the Feeder Ammeter Clear Test (FACT-1) operation
and issues that may influence its performance is key to obtaining the maximum
effectiveness of this unit.
The FACT-1 outputs 120VAC to the cable under test and therefore extreme caution must
be exercised to prevent electrical shock.
Never obstruct the intake or exhaust grills in the cord storage compartment.
Never attempt to close the cover while the unit is operating or while any cables are
connected.
Do not connect the FACT-1 unit to a GF protected circuit.
Before connecting the FACT to any circuit, test and ground that circuit to verify it is both
de-energized and discharged.
DO NOT use the FACT-1 if any chance of a back feed exists.
The FACT-1 contains sensitive electronic parts. Although the housing is rugged, care
should be taken to prevent any impact to the unit. An impact could damage the internal
circuitry or display. The unit should never be opened except by the manufacturer. No user
serviceable parts are inside.

FACT-1 DESCR PT ON
Alternating Current (AC) Ammeter Clear tests are used to indicate the presence of either
grounds or short circuits on a primary feeder's three phase conductors or either grounds
or short circuits on transformer secondaries.
ntentional grounding of the feeder cables may occur during some types of maintenance.
Failure to remove these grounds at the end of the maintenance procedure is unintentional
but nevertheless could cause potential damage if an attempt is made to put the feeder
back in service.
The Feeder Ammeter Clear Test Set has been specifically designed for utilities that do not
or cannot disconnect their transformers from the primary cable under test. A 120V AC,
60Hz source is used to check for grounds or short circuits. The AC signal is also adequate
to energize the transformers connected to the feeder sufficiently enough to detect
grounds left on the secondary side of a transformer.
n the primary phase-to-ground fault scenario, the LCD ammeter display will indicate a
fault current of approximately 5 Amps with a nominal line voltage of 120V. A maximum of
5 Amps is provided by the Test Set and is limited by an internal 24 ohm power resistor. n
the primary phase-to-phase fault scenario, the LCD ammeter display will also indicate a
fault current of approximately 5 Amps with a nominal line voltage of 120V.
n the secondary side fault scenario, a short circuit fault from a feeder transformer
secondary conductor to ground occurs. This allows more current to flow through the
primary windings of this transformer which current then flows through the primary
feeder. The value of the current flowing will depend on the nominal voltage of the
feeder being tested since the turns ratio of the transformer will vary. For example,
when a 13.8kV primary feeder connected to a transformer with a 120V secondary
is tested, the LCD ammeter display reading would be about four amperes while on
a 27kV feeder with a transformer to 120V, the LCD ammeter display reading would
be about 1.4 amperes. These are only estimates and can vary depending on feeder
voltage and the type of wire (impedance) used to ground the feeder.
Under a "No Fault" condition, the LCD ammeter display will generally indicate a fault
current of less than about O.3A and will indicate that No Fault has occurred. This ammeter
reading would then represent the sum of transformer excitation currents on a given typical
feeder should said transformers not be disconnected from feeder on the primary side.

FACT-1 FRONT PANEL DESCR PT ON
1. TEST CABLE CONNECTOR - 3 binding posts for making connections to the individual
phases of the feeder. Each post is labeled to correspond to a particular phase of the feeder.
2. LCD DISPLA - The Liquid Crystal Display (LCD) for displaying instructions, messages,
and ammeter current.
3. SELECTOR KNOB - This rotary switch selects which phase is being tested at any
given time. When the knob is in the STANDBY position, no phase is selected.
4. SELF-TEST - Pressing this button initiates the Feeder All Clear Test Set the self-test
mode to assure proper operation. The test cable assembly must be removed during
the self test.
5. POWER - This button is the master power switch for the Feeder Ammeter Clear Test
Set. t is a latching pushbutton type. Pressing this button powers up all the electronics
and fan for operation
6. AMMETER CLEAR - Pressing this button provides 120V AC to the selected binding
post (Phase). t is a momentary pushbutton type. The button should not be pressed for
long periods of time since substantial heat can develop in the unit when there is a
ground on the feeder.
7. POWER CORD - Power cord for the unit. Cord must only plug into a 120V AC, 60Hz,
non-GFC 15 ampere outlet.

US NG THE FACT-1
CAUTION: Steps 1 through 6 should he performed with the feeder "grounded".
1. Make sure test cable assembly is NOT connected to the FACT-1.
2. Plug the FACT-1into a 120V, 60Hz, 3-prong outlet. The outlet should be rated for
a minimum of 15 Amps. Press the Red POWER switch to turn on the unit. The
POWER switch should illuminate and the fan located in the cord cavity should start.
IMPORTANT: The FACT-1 is not designed to work with any type of GFC protection device.
n a situation where a ground is left connected to the feeder, the FACT-1 will output current
on the corresponding phase however, the return current will be on the neutral/sheath of
the feeder and/or earth ground. Therefore the GFC device will detect the large differential
in current and open the circuit, prohibiting the unit from operating.
3. Perform a "Self-Test" of the unit prior to normal operation (see "Diagnostics").
IMPORTANT: The test cable assembly should NOT be connected to the FACT-1
during the Self-Test or the results may be incorrect and the test leads will become
energized with 120V.
4. Turn off the power to the unit by pressing the POWER switch again. The POWER switch
should no longer be illuminated and the fan will stop.
CAUTION: Assure that the feeder cable being connected to the FACT-1 is not energized.
The Feeder Ammeter Clear Test Set is not designed to be used or connected in the presence
of voltages greater than 300V.
5. Connect the test cable assembly to the FACT-1. Connect the appropriate test leads to
the A, B and C phase of the cables under test. Connect the ground lead to the neutral.
6. Turn the power on to the unit by pressing the POWER button.
NOTE: f for some reason the 3rd prong safety ground is not connected properly, a
message will be displayed on the LCD to repair the 3rd prong ground before operating.
CAUTION: The Feeder grounds need to be removed at this point. Assure there is no back
feed condition or voltage being applied to the feeder prior to the removal of the grounds.
IMPORTANT: The FACT-1 has been designed to also operate in situations where the polarity
of the 120 VA C outlet is "reversed". When the polarity is reversed, the output post that
becomes "live" when the AMMETER CLEAR button is pressed is also reversed. This will
be indicated on the LCD so that the operator does not have to remember; he simply
rotates the selector knob until the phase he wishes to test is indicated on the display.
The table below describes the internal logic:

6
120V Source Rotary Switch Phase to Ground Test Phase to Phase Test
Polarity Position (Output Phase) (Output Phase/Return Phase)
Correct Standby OFF OFF
Correct A PHASE A PHASE A to PHASE B
Correct B PHASE B PHASE B to PHASE C
Correct C PHASE C PHASE C to PHASE A
Reversed Standby OFF OFF
Reversed A PHASE B PHASE B to PHASE A
Reversed B PHASE C PHASE C to PHASE B
Reversed C PHASE A PHASE A to PHASE C
7. After the unit initializes, rotate the Selector Knob to Position A. The LCD will indicate
which phase the 120V AC voltage will be applied to.
8. Press and hold the AMMETER CLEAR button for several seconds. f there is any significant
current flow, the digital ammeter will display the current flow in 0.25Amp increments. f
there are no grounds connected to the phase either on the primary or secondary of a
transformer, and the phase indicated is not shorted to another, then the "NO FAULT"
message will be displayed:
A-ALIVE
NO FAULT DETECTED
Depending on the number of transformers connected to the network feeder during the
test, some small current (<0.3Amp) could be detectable due to the excitation currents of
the transformers. f the FACT-1 detects maximum current flow in the "live" (selected)
phase only, a phase to ground fault exists and is displayed:
A-ALIVE
PHASE A TO GND FAULT
f the FACT-1 detects maximum equal current in the output phase and the return phase,
then a phase-to-phase fault exists and is displayed:
B-ALIVE
PHASE B TO C FAULT
f the FACT-1 is operating with the transformer primaries connected to a feeder and a
ground is present on the secondary, the FACT-1 will detect its presence and display only
a partial reading. The actual reading obtained for a secondary fault will be dependent on
the windings of the transformer (turns-ratio) and the size (gauge) of the grounding
conductor. The heavier the grounding wire, the higher the current will be for secondary
faults. When secondary faults exist, they will be displayed as a phase-to-phase fault.
B-ALIVE
PHASE B TO C FAULT

9. After the selected phase has been tested and the AMMETER CLEAR button is released,
rotate the select knob to another position to test the other phases and repeat step 7
for each phase. The LCD will always indicate which phase that is being tested.
THERMAL OVERLOAD
The FACT-1 contains several resistors to limit the current supplied to the selected phase.
Since these resistors are required to dissipate several hundred watts, significant heat can
build up inside the case if the AMMETER CLEAR button is pressed for a long time on a
faulted cable. f the internal sensor detects a temperature that is too high, a message will
be displayed to the LCD:
Unit Temperature is Too High. Please Allow to Cool (with power switch on)
f this situation occurs, leave the FACT-1 plugged in with the POWER switch ON. This will
operate the fan and reduce the internal temperature. When the unit temperature' drops to
an operational level, the message will disappear and the unit may be used for testing again.
REVERSED POLARIT OPERATION
The FACT-1 has been designed to not only protect against an incorrectly wired outlet, but
to operate normally if such a situation arises. f the unit detects incorrect polarity, a message
is displayed to the operator to alert him of the situation. The operator must then press the
SELF-TEST button momentarily to clear the notice:
NOTICE: L NE CORD POLAR TY S REVERSED PRESS SELF-TEST TO CONT NUE
DIAGNOSTICS
The FACT-1 has built-in comprehensive diagnostics to assure that the FACT-1 is operating
correctly. The test cable assembly should NOT be connected to the FACT-1 during the Self-
Test. The Self Test mode is entered by pressing the SELF-TEST button. f at any time, you wish
to exit the Self-Test mode, simply press the SELF-TEST button a second time. The FACT-1 will
guide the operator through the Self-Test procedure using messages on the LCD.
Once Self-Test mode is entered, a message will be displayed to rotate the selector knob
to the correct position:
Rotate Switch to Pos A, then Press & Hold Ammeter Clear Button
(Self-Test to Cancel)
f the selector knob was already in that position or if the selector knob is rotated to that
position, the LCD will instruct the operator to press & hold the AMMETER CLEAR button
until a test PASS or test FA L message is displayed. Once the AMMETER CLEAR button
is released, the operator will be instructed to rotate the selector knob to each of the
remaining positions and to press the AMMETER CLEAR button.
At the conclusion of the test, an ALL TESTS PASSED or TEST FA LURE message will be
displayed before returning to normal operation.
The FACT-1 should never be operated outside of its maximum operating temperature
range of -20C to +60C (-4F to +140F). Operating the FACTS outside of its temperature
range may permanently damage the unit.
