4.3.3 After Calibration is
Complete
The message “Calibration Complete” appears
when all SMT calibration steps are complete,
regardless of the results. There will be three
options available after the calibration has
completed.
• Validate
• Save to EEPROM (If the Save to RAM & EEPROM
radio button is selected on the Connection
Manager Window)
• Create Report
Each of these are described in separate sections
below.
4.3.3.1 Validate
4.3.3.2 Save to EEPROM
By validating the calibration, you are levitating
the shaft using the current stored calibration
data. If you validate before Saving to EEPROM,
the latest calibration data has no impact on the
shaft position.
A bearing calibration is not required to have
been performed in order to validate (levitate) the
shaft. Using the validation process in this manner
will allow the technician to know if the shaft can
levitate freely using the current stored calibration
data.
When saving to the EEPROM, the “latest”
calibration values overwrite “stored” values.
There is no requirement to save calibrations to
EEPROM after performing a bearing calibration.
Comparing original factory calibration values
stored in EEPROM to the latest calibration allows
determination of long term changes.
Saving to EEPROM permanently overwrites
existing stored calibration values. “Stored” values
are used for startup check at the next power
cycle. The previous values cannot be recovered
once the new values are saved to EEPROM.
Original calibration values should only be
overwritten when replacing a BMCC in the field,
or when required for troubleshooting a bearing
issue with a compressor.
NOTE
If the latest calibration values differ from the stored values outside of the tolerances set in the SMT, a warning message will appear
when saving to the EEPROM.
This compares changes from the stored calibration to the latest and may be an indicator of shaft/bearing alignment changes over
time.
4.3.4 Create a Calibration
Report
The calibration report compares current bearing
calibration values to stored values. There is no
requirement to perform a bearing calibration
before creating a calibration report. There is also
no requirement for saving a bearing calibration
(if performed) to EEPROM before creating a
calibration report.
Perform the following steps to create a report:
1. Click the Calibration Report button.
2. Select a location to save the report. The report
will be generated as a Portable Document Format
(PDF) document.
