MODULE 3-REVIEW QUESTIONS AND CASE STUDIES
SCENARIO 1
During an ci8200
®
System installation the following error occurred during STARTUP.
The following troubleshooting STEPs were performed and the issues was unresolved:
• Reseated and checked cables at SIB and transport
• Swapped Indexer Boards
What checks, measurements, procedures, etc. would you use to help isolate the root cause of the
failure? What would you do to try and resolve this error? What is the most likely cause of the
failure?
Since this error is from the Carrier Transport and the actual reading is a 0 compared to the
expected reading of 72; the most likely cause is a failed Section Align Sensor. A zero reading
indicates there was no data collected, or reported, from the Section Align Sensor as it is the sensor
reading the notches for the actual data.
Other potential causes such as a damaged flex cable or RSH extrusion not properly assembled
could cause this error, but would most likely not report a zero for the actual reading.
SCENARIO 2 Intermittent Carrier Rail Guide Sensor errors.
The following troubleshooting STEPs were performed, but the errors remain unresolved:
• Rail Guide Sensor Board was replaced
• Cables on SIB and transport were reseated
• Indexer Board was replaced
What checks, measurements, procedures, etc. would you use to help isolate the root cause of the
failure? What would you do to try and resolve this error? What do you think may be causing the
failure?
The most likely cause of this error would be due to one or more Carriers in use are too short for
the Transport Rail Guide Sensor.
