•
One or more of the gains are zero
Interpretation: There is an electrical fault.
Refer to the Troubleshooting Manual for the appropriate
troubleshooting procedure.
•
The difference between the “Latest Check” and
“Stored Calibration” is less than 20% of the “Stored
Calibration” value
Interpretation: Bearing calibration was successful.
•
The difference between the “Latest Check” and
“Stored Calibration” is greater than 20% of the
“Stored Calibration” value
Interpretation: Excess carbon obstructing the shaft.
Refer to the Troubleshooting Manual for the appropriate
troubleshooting procedure.
“Offset” Interpretation
Only the difference between the “Latest Check” offset and
the “Stored Calibration” offset is important. The “Latest
Check” offset value or the “Stored Calibration” offset value
by itself has no significance. The change between the offset
values signifies a change in the area of shaft orbit.
