TROUBLESHOOTING INFORMATION
General
This system is designed for ease in troubleshooting and repair. The various indicators,
as described in Chapter 3. System Operating Procedures, are designed to isolate a
failure to a specific element. Once the faulty element has been identified, refer to the
next sections, “Replacement Information” and "Replacement Procedures".
The procedures listed in Chapter 5. System Maintenance, can also be used by servicing
personnel in identification and/or prevention of trouble symptoms in the system.
Adjustments
If the suspected cause of a trouble symptom is an out of adjustment condition, that
particular adjustment setting should be checked or reset using the appropriate
adjustment procedure detailed in Chapter 4. MCA System Adjustments. If a failed
Rectifier or circuit card is suspected, the adjustment procedures can also be used to
verify the setpoints as well as the operation of the Rectifier or circuit card.
MCA Messages
An MCA Menu Tree (Section 5886) is provided in the separate INSTALLATION MANUAL
and the CD CARRIER MANUAL (it is also provided on the CD). Each line in the MCA
Menu Tree contains a number. This number is referenced in a chart provided in Chapter
2. Navigating the MCA. This chart provides a description of each line listed on the MCA
Menu Tree.
If the MCA displays an alarm message, find the line in the MCA Menu Tree showing this
message. For an explanation of this alarm, locate the corresponding MCA Menu Tree
Line Number in the chart provided in Chapter 2. Navigating the MCA.
Note: If the MCA is replaced with an MCA previously used in another power system, the
MCA may reflect inventory items not in the current power system and may display
alarms. In this case, update the inventory as detailed in this chapter. Also, if you
remove an inventory item (a component) from the power system, you must update
the inventory to clear alarms.
Note: If you remove a Battery Charge Digital Temperature Compensation Probe, alarms
are displayed. Manually set the Battery Charge Digital Temperature
Compensation feature to off as described in "Chapter 4. MCA System
Adjustments" to clear the alarms.
