Clearing Last Trip Data
It is very important to clear the Last Trip Data
from the trip unit after testing is complete.
Leaving the Last Trip Data in the trip unit will
later cause confusion for operating personnel.
Follow the Instructions in the AC-PRO or
AC-PRO-II trip unit Instruction Manual.

Error/Fault Conditions
7.1
Current Error
The test set monitors the current level while a
test is in progress. Should the current level be
outside of the expected range, a current error
will occur and the test set will stop current flow
and display “Current Error”.
To clear the current error the Clear (8) button
must be pressed. After this, normal operation
on the test set should be restored after the
reason causing the error is corrected.
The most likely causes for a "Current Error"
are:
1)
The trip unit is not powered up.
2)
There are loose connections in the test
cable.
7.2
Thermal Limit
As a protective feature, the test set will stop
delivering current and display a “Thermal
Limit” message if high levels of test current
remain for a prolonged time period. The
timeout for the thermal limit shutdown begins
when any test current exceeds eight amps.
If a thermal limit occurs it must be cleared by
pressing the Clear (8) button. The test set will
not allow a test to be restarted for about five
seconds. Before restarting the test, verify that
there are no loose connections.
7.3
Unexpected GF Trip
If a GF trip occurs when the Phase Selector
(11) switch is NOT set to GF, the Ground
Fault Type (10) selector switch may be
incorrectly set to "Ground Return" instead
of "Standard GF".
