Diagnostic Code - Troubleshoot
The CCM has internal troubleshooting to aid in solving various system problems.
Show/hide table
| CCM Error Codes | ||
| CCM Error Code | Explanation | Action Required |
| E00 (all bits zero) | No fault, normal operating mode | None |
| E01 (bit 1 set) | Setpoint fault | CCM passwords or communication setups are corrupted. Reprogram from Connection and Setup pull-down menus. |
| E02 (bit 2 set) | M50 message error | Check customer generated M50 code |
| E03 (bit 3 set) | Memory backup battery is weak | Change battery. Refer to Operation and Maintenance Manual, SEBU7014, "Battery - Replace" in this manual. |
| E04 (bit 4 set) | RS-232C link short circuit fault | Check RS-232C cable, PC port, and CCM port |
| E05 (bit 5 set) | Internal buffer overflow on RS-232C or Data Link fault | Possibly caused by a slower than acceptable communication rate from the RS-232C port or an open CAT Data Link connection during RS-232C transmission. Increase communication rate and check CAT Data Link wires. |
| E06 (bit 6 set) | Invalid CAT Data Link Message fault | Caused by:
1. Too much traffic on CAT Data Link. 2. CAT Data Link wires too long. |
| E07 (bit 7 set) | Miscellaneous CAT Data Link Fault | Caused by:
1. (+/-) CAT Data Link shorted to (+/-) battery. 2. Internal hardware fault in CCM. Check CAT Data Link wiring and then replace CCM if wiring is good. |
| E08 (bit 8 set) | RS-232C link message fault (parity, data size) | Check RS-232C protocol (communication rate, data bits, stop bits, parity) of CCM and host equipment. |
| E.. (bits 16-9) | - | Set to zero (0). Reserved for future use. |
