5.1.2  
  Module Disassembly 
 
The following procedure should be used to disassemble any model prior to any maintenance. 
 
(1)  Place the scanner with its external connectors facing up.  With one hand holding the  
module housing,  remove all screws securing the top plate to the module housing.  These are 
located around the outer edge of the top panel of the module housing. The Model 9116 uses 
twelve (12) Phillips head screws around the top plate outside perimeter. 
 
(2)  When all screws have been removed, gently lift the top panel and attached electronics up 
and out of the housing.  All components of the pressure scanner are attached to the top plate 
and will lift out of the module housing when the top plate is removed.  See Figure 5.2.  Carefully 
remove the Viton gasket with the module top plate.  In some cases, it may be easier to hold the 
top plate and turn the module over, lifting the housing off the top panel. 
 
5.1.3  
  Electronic Circuit Board Replacement 
 
 The Model 9116 contains three (3) printed circuit boards (PCB); the PC-322 main board, the 
PC-323 PowerPC Daughter board, and the PC-327 analog board.  However, the PC-322 and 
PC323 boards are normally left attached to each other and are treated as a single assembly.
