Tools User Manual for use instructions.
6. If you can still not connect to the compressor, verify the Backplane and the BMCC.
4.3.2.3 Interlock Verification
1. Ensure the compressor interface cable is properly attached to the Backplane and to the CIM and the
BMCC is properly attached to the Backplane.
2. Remove the J2 connector from the I/O board.
3. Using a multimeter set for DC voltage, measure the voltage between I/LOCK+ and I/LOCK-.
l
The voltage should be 2.2 - 3.7VDC.
4. Install the J2 connector to the CIM.
5. Ensure the circuit connected to I/LOCK+ and I/LOCK- on the CIM (port J2) is closed.
6. Measure the voltage at I/LOCK- to the common ground point.
l
The measured value at I/LOCK- should be 0VDC.
o
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.”
l
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-.
l
Resistance should be < 22.2kΩ; if not, the interlock circuit is damaged and the BMCC needs to be
replaced.
l
Refer to Section 5.5.3 Troubleshooting an Open Interlock on page 273 for further details.
4.3.3 Compressor Interface Module Removal & Installation
• • •DANGER!• • •
Ensure there is no secondary power source connected to the Compressor I/O Board before disconnecting the I/O cable.
4.3.3.1 Compressor Interface Module Removal
1. Isolate compressor power and wait for the D9 LED to turn off on the CIM.
2. Remove all external connections from the CIM.
3. Using a screwdriver, apply leverage toward the left while lifting the right side of the CIM. Refer to
Figure 4-19 Removing the Compressor Interface Module from the DIN Rail on page 64.
4. Repeat the procedure for the other mounting foot to disengage the CIM from the DIN rail.
