Module ReĆassembly

Re-assemble the module using the following procedure.

1.

Turn off +5V dc and +15V dc.

2.

Remove the analog and digital circuit boards from the I/O chassis
and disconnect the extender board from the analog board.

3.

Apply pot sealer to the adjusting screws to indicate whether or not
any of the pots had been adjusted between calibrations.

4.

Remove the jumper from the digital board.

5.

Check all programming plug locations on the analog board to ensure
they are returned to their initial positions as recorded earlier in
section titled Installation.

6.

Carefully re-assemble the module. Be sure that the programming
plug locations at E11 and E12, if in the OUT position, do not
interfere with the front cover flange. Also be sure that the three stake
pins mate with their respective sockets on the digital circuit board.
