This section provides some very basic troubleshooting guide-
lines for the OIS43 console. It is not meant to be all inclusive.
Make certain all the manufacturer’s documentation on non

instruction manuals (Elsag-Bailey) should be on hand;

tion

. Those instruction
numbers are listed in Table
. Many of these documents pro-
vide troubleshooting information. If problems exist which are
not covered in any of the provided documentation, contact
Elsag-Bailey technical services personnel for assistance.
This section contains a general troubleshooting table, diagnos-
tic AC/DC power test procedures, module failure LED codes
and techniques for gathering information on software faults.
Close and secure cabinet doors after troubleshooting and
before returning the system to normal operation.
NOTE: Put circuit boards containing MOS devices into antistatic
bags when stored or shipped back to the factory.
Do not repair
printed circuit boards in the field. All repairs and adjustments should
be performed by qualified personnel.
