If a new fault is logged while viewing the fault log, the screen is not changed, it will
continue to show the old fault. This allows the fault data to be viewed if several faults are
logged rapidly. To refresh the screen, and show the current fault in that fault location,
press Ent.
NOTE: All faults will be cleared when a Factory Reset is performed.
Non-shutdown faults can be prevented from being logged, if desired. See the
list of Adjustable Features on sheet “MH
-
3000 Settings”. One of the Bit Features
will be
labeled “Disa
ble Non-
Shutdown Faults in the Fault Log”. Turn this feature on to disable
non-shutdown faults. This may be useful if you are trying to track down a specific fault, and
you do not want the fault log to contain minor faults. Refer to the section on Changing
Features for instructions on settings the proper Bit Feature to disable non-shutdown faults.

hexadecimal number from 00 to 3E (decimal 62), with 00 being the most recent fault.

the next most recent fault. You can press 0 to jump to the most recent fault (fault 00).

Fault Time Stamp
“09:40” is the time stamp for the fault, shown in the middle of the top line of the “Fault
Log
” screen. The time is displayed in 24hour for
mat. The time stamp is accurate to within
10 minutes, so if the fault time is 09:40, as shown above, then the fault occurred between
9:40 and 9:49.
NOTE: Faults that happen within 10 minutes of each other may log the same
time. The fault # will indicate the order of occurrence.
If the real time clock is set correctly, then this will be the time of the fault.
NOTE: To set the clock, refer to the section on setting the time under MH-
3000 Screens and Diagnostics/Set-Up Mode/Set the Time.
To verify that the real time clock is set, press
