4.3.5 Calibration Report
Analysis
1.
Data in Report:
The difference between the
“Latest Calibration” and “Stored Calibration” is less
than 30 percent.
• Interpretation:
Successful calibration.
2.
Data in Report:
Only one of the gain values
equals zero.
• Interpretation:
Bearing or bearing sensor
electrical fault, or one channel of the PWM
Amplifier is faulty.
• Action:
Verify the PWM.
• Action:
Verify the bearings.
• Action:
Verify the bearing sensors.
3.
Data in Report:
More than one of the gain
values is zero.
• Interpretation:
Incorrect calibration procedure
performed, bearing or bearing sensor electrical
fault, or more than one channel of the PWM
Amplifier is faulty.
• Action:
Before beginning the calibration,
verify the Interlock is open and all external
communication is disconnected.
• Action:
Verify the PWM.
• Action:
Verify the bearings.
• Action:
Verify the bearing sensors.
4.
Data in Report:
One or more of the gain values
exceeds 3.0.
• Interpretation:
Bearing electrical fault or shaft
is obstructed.
• Action:
Verify the bearings.
• Action:
Verify the bearing sensors.
See Figure 98 (Bearing Calibration Flow).
5.
Data in Report:
One or more of the bearing
Force Current values exceeds 1.5A in Validation
Results.
• Interpretation:
Bearing electrical fault or shaft
is obstructed.
• Action:
Verify the bearings.
• Action:
Verify the bearing sensors.
See Figure 98 (Bearing Calibration Flow) .
6.
Data in Report:
The difference between the
“Latest Calibration” and “Stored Calibration” is
greater than 30 percent.
• Interpretation:
Bearing/Shaft position has
changed from stored to latest.
• Action:
Save to EEPROM and cycle power; test
run compressor with new values.
• Action:
Verify the bearings.
• Action:
Verify the bearing sensors.
See Figure 98 (Bearing Calibration Flow).
