Figure 4-249 BMCC Removal
4.27.4.2 BMCC Installation
• • • CAUTION • • •
When installing a new BMCC or moving one from a different compressor, a bearing calibration must be performed and saved to electrically
erasable programmable read-only memory (EEPROM). The BMCC will then use the new values stored in EEPROM to operate the
compressor. Using default calibration data from a newly installed BMCC to operate a compressor could cause unexpected behavior.
Additionally, new compressors and BMCCs by default, are set to the lowest amperage limits and must be configured to meet the system
requirements.
1. Align the two (2) lower insertion guides of the BMCC so that they are on the inside of the two (2) upper
insertion guides on the Bearing PWM Amplifier. Refer to Figure 4-250 BMCC Insertion Guides.
Figure 4-250 BMCC Insertion Guides
2. Slide the BMCC straight into the connector until firmly seated in the Backplane connector.
3. Install the Serial Driver. Refer to Section 4.26.4 Serial Driver Removal and Installation on page 218.
4. Install Service Side Cover. Refer to Section 4.1.3 Service Side Cover on page 54.
5. Return the compressor to normal operation.
