USING 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 GFCI protection device.
In 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 GFCI 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:
If 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:
