5.1.2Module Disassembly

The following procedure should be used to remove modules from the 98RK-1 Scanner Interface Rack prior to any scanner maintenance.

(1)Remove the module from the 98RK-1 Scanner Interface Rack by unscrewing the locking rod (turn counterclockwise with a 5/64" Allen-head screwdriver) and slide the entire module chassis out of the rack.

(2)Place the scanner on a flat surface. Remove the six (6) #0 Phillips-head screws that hold each of the side covers on the scanner. Remove one or both side covers (if your maintenance requires removal of both sides). Place the scanner with its front toward you. Notice that the locking rod holes are drilled slightly off-center of the panel and that the rod extends to the side of the tubing cluster. This facilitates removal of the transducer/cal-valve housing when maintenance needs to be performed. Note, DO NOT completely remove the locking rod unless there is an overriding need to do so. The small “c” spring clamp requires a special tool for removal and the clamp itself is easily lost.

(3)If your maintenance requires doing so, unplug the manifold position detector four-pin connector from the PC-299 board at P-12 (see Figure 5.3 below).
