design tolerance.
M. There are additional ERROR messages which may ap-
pear on the display during this operation which were not
covered previously:
Test Not Running! Check test cable connection.
Press ENTER to continue.
The test set has sensed that current is not flowing
properly in the breaker under test and that there is either
an open or short circuit between the TS-31 and the
breaker trip unit.
Function Not Available
Press ENTER to continue.
You will get this error message if you enter a choice that
is not available, such as entering "G" in step F for ground
fault test on a catalog number that does not have ground
fault.
Inconclusive Test, check settings
Press ENTER to continue or A to abort
NOTE: This warning will appear if you attempt to run a short
time test with the instantaneous pickup set equal to or
below the short time pickup. It would also appear if you
tried to run a long time test with short time pickup set to
2. This is only a warning; the test can still be run. However,
passing or failing the test may not be conclusive
Invalid Input
Press Enter to continue
NOTE: This message will appear if you enter a setting value
that does not exist. For example, a SMD69700NGT has
continuous current settings of 20~ 30, 35, 40, 50, 65, 70,
80, 90, and 100 percent. If you were to enter any other
value that those listed, the above message would ap-
pear.
Test exceeds capability of TS-31
Press ENTER to continue
NOTE: This message is not likely to occur. If it does, it means
that a test requires more current to run than the TS-31
can produce.
Unit too hot, please wait
NOTE: Running many successive high-current long time tests
may over-heat the test set. It will protect itself from
damage by preventing further tests until it has had a
chance to cool down. The display will indicate when
testing can resume.
