ASSEMBLY INSTRUCTIONS
CAUTION:
THE FA2100 CIRCUIT BOARDS ARE SUSCEPTIBLE TO ELECTRO–
STATIC DESTRUCTION (ESD). PRIOR TO HANDLING PWAs, ENSURE
PROPER PERSONNEL GROUNDING TECHNIQUES ARE USED.
ENSURE THAT CARDS ARE PLACED INTO STATIC SHIELDING
CONDUCTIVE BAGS WHEN HANDLING OR STORING.
A.
General Assembly Techniques
The Model FA2100CVR circuit board components are mounted using Surface Mount
Technology (SMT) and also incorporate extensive software programming to function-
ally configure the logic circuits. Thus, Level-3 repair of these circuit boards requires
specialized factory equipment, diagnostic software, training, and techniques; there-
fore, such boards are not field-repairable while the unit is under warranty. Conse-
quently, in accordance with the accepted Level-2 repair philosophy for the FA2100
CVR, a known defective circuit board assembly shall be returned to the factory for
repair or replacement.
NOTE:
Numbers shown in parentheses in the following text are the
Illustrated Parts List (IPL) figure number followed by the IPL
item number for a particular part; e.g., (1-115) for IPL Figure 1,
Item 115. For items listed in the parts list but not illustrated, the
item number is preceded by a “-”.
The Assembly procedures begin with the Acquisition Processor PWA installation
then continue with the Audio Compressor and Aircraft Interface PWA installation,
CSMU installation, and Underwater Acoustic Beacon installation.
B.
Acquisition Processor (AP) PWA Installation
(See Figure 701 or IPL Figure 1, Item 175)
This procedure assumes that the Crash Survivable Memory Unit (CSMU) is removed
from the chassis and that the rear panel chassis assembly with the Aircraft Interface
PWA and Audio Compressor PWA attached is also removed from the recorder chas-
sis. The Model FA2100’s Acquisition Processor (AP) PWA (1-175) is mounted in the
bottom of the recorder chassis just below the CSMU.
