• The measured value at I/LOCK- should be 0VDC.
– If the measured value is not 0VDC, locate and remove the source of the voltage.
7. Open the SMT
Compressor Monitor
tool.
8. With the system interlock circuit remaining closed, verify the
Compressor Interlock Status
states
“Closed.”
• If the
Compressor Interlock Status
states “Open,” the interlock circuit is damaged and the
BMCC needs to be replaced.
9. Isolate compressor power.
10. Remove the J2 connector from the CIM.
11. Using a multimeter for resistance measurement. Place the meter probes on I/LOCK+ and I/
LOCK-.
• Resistance should be < 22.2kΩ; if not, the interlock circuit is damaged and the BMCC needs
to be replaced.
• Refer to "5.5.3 Troubleshooting an Open Interlock" on page 259 for further details.
4.4.3 Compressor Interface Module Removal & Installation
4.4.3.1 Compressor Interface Module Removal

4.4.3.2 Compressor I/O Board Installation
1. Install the left foot of the replacement board into the rail and press the right side of the board
down until it engages the rail.
2. Reconnect all external connections and wiring on the CIM.
3. Return the compressor to normal operation.
4.5 Compressor Interface Cable
The Compressor Interface Cable connects the compressor to the CIM. Refer to "Figure 4-20
Compressor Interface Cable" on page 67 for an overall view of the cable installation.
• • • DANGER • • •
Ensure there is no secondary power source connected to the Compressor I/O Board before disconnecting the I/O cable.
