Installing a new power board:
1) Place the power board over the main PCBA. Align the two external connectors (patient
assist and comm. port) with the two square holes in the side of the upper weldment and
align the 64-pin female connector on the power PCBA with the 64-pin male connector
on the main PCBA (see illustration).
2) Attach the power board to the main PCBA by pressing down directly on the JP12, 64-
pin header. The power board should seat on the main PCBA such that the pins on the
main PCBA are visible through the top of the connector on the power board.
3) Thread two 3/16" pan-head screws (P/N 14372) through the power board into the
standoffs on either side of the 64-pin female connector on the power board. Torque-
tighten to 60 in-oz (0.42 Nm).
4) Insert two 7/16" pan-head screws (P/N 10433), one into the mounting hole closest to
U36 on the power board and one into the mounting hole nearest the sounder location.
Torque-tighten both screws to 60 in-oz (0.42 Nm).
5) If removed, reconnect the flexible tube from the tee and port A of the accumulator, to
port #9 on the front of the solenoid manifold.
