MODEL 5081-T SECTION 11.0
MAINTENANCE
FIGURE 11-2. Exploded View of Model 5081-T Transmitter
Three screws (part 13 in the drawing) hold the three circuit boards in place. Removing the screws allows the display board (part 2) and the
CPU board (part 3) to be easily removed. A ribbon cable connects the boards. The cable plugs into the CPU board and is permanently
attached to the display board. A 16 pin and socket connector holds the CPU and analog (part 4) boards together. Five screws hold the ter-
minal block (part 5) to the center housing (part 7), and the 16 pins on the terminal block mate with 16 sockets on the back side of the ana-
log board. Use caution when separating the terminal block from the analog board. The pin and socket connection is tight.
