How can we help you today?
Why does the FFTK screen occasionally display "Failed" when performing the short time test right after the long time test in automatic mode for Micrologic A, P, and H trip units?
Issue:
"Failed" indication during Automatic Trip Curve Test with Full Function Test Kit (FFTK)

Product Line:
FFTK for Micrologic A/P/H trip units

Resolution:
This is normal due to the overlapping short time and long time curves. Wait at least 10 seconds after the long time test before performing the short time test.
