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. If 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)
If 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 POLARITY 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. If 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:
LINE CORD POLARITY IS REVERSED PRESS SELF-TEST TO CONTINUE
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. If 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)
If 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 FAIL 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 FAILURE 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.
