Section 6: Troubleshooting
Listed below are resolutions to common problems experienced with
MTK2000 . Please review this section prior to contacting Eaton with
questions .
Trip Unit keeps indicating the wrong type of trip (i.e. Long Delay
Trip when testing Short Delay Pickup).
Verify that the trip unit is set correctly as indicated on the MTK2000
prior to Starting the test and that the trip unit is reset prior to
Starting a test . Verify that the Zone Interlock plug is installed when
the breaker is removed past the Test Position or is removed from the
cell .
Measured values for a particular Digitrip are not consistent with
settings on the Digitrip.
Press
Cancel
twice to reach the Home Screen . Proceed as normal
and ensure that the MTK2000 performs the self calibration proce-
dure with the new Digitrip . Verify that the thermal memory jumper is
in the correct position or setting (see paragraph 2 .2 .2) . Ensure that
the SD Card provided from the factory is installed in the MTK2000
and still has the original calibration data stored .
Digitrip seems not to respond to input from the MTK2000.
Verify that the Digitrip Cable is plugged correctly into the Digitrip as
well as the rear of the MTK2000 .
Long Delay Times seem to decrease during testing.
Verify that the thermal memory jumper is in the correct position (see
paragraph 2 .2 .2)
The values on the MTK2000 Test Kit and the values on my
metering Digitrip do not match.
It is important to understand that the Digitrip has a tolerance band
within which it is expected to perform . Some difference is accept-
able, although this value should be minimal .
