Compressor Components
Communication
1. Connect to the CCM using the SMT and enter the User ID and Access Code.
2. Open the Warnings and Faults Tool.
3. Verify that the CIM Compatibility, controller area network (CAN) Communications and VFD
Communications Faults are not active.
Calibration
A calibration should only be saved to EEPROM if there is a known bearing problem or when a new/
dierent Service Electronics Assembly is replaced.
1. Power on the Compressor.
2. Using the SMT, perform a compressor bearing calibration and save to EEPROM.
3. Select validation to test bearing levitation control.
4. Create and save a calibration report for records and review.

• • • CAUTION • • •
When replacing the Service Electronics Assembly, a bearing calibration must be performed and
saved to the EEPROM. The Service Electronics Assembly will then use the new values stored in
EEPROM to operate the compressor. Using default calibration data from a newly installed Service
Electronics Assembly to operate a compressor could cause erratic behavior.
