Module Assembly
Carefully align the main processor and I/O processor boards
on their metal frame, guiding the four 96-pin DIN connectors
through the slots in the metal frame.
Slide the three cylindrical metal spacers through the holes in
the two boards. Slide the two medium length panhead screws
into the screw holes and partially tighten (do not fully tighten
the screws yet).
Check the alignment of the three cylindrical metal spacers.
The spacers should be positioned straight up and down (and
not tilted at an angle). The spacers and the circuit boards
must be correctly aligned or the module may not insert
smoothly into the controller chassis
If you insert the long screws from the underside of the module
and through the holes and spacers, the circuit boards should
be easier to align. When the circuit boards are aligned
correctly the screws should slide freely within the cylindrical
metal spacers.
Tighten the two screws holding the printed circuit boards to
the metal frame.
Place the circuit board assembly on top of the rest of the
module. The two screw holes in the circuit board assembly
should align with the two threaded screw holes in the module’s
face plate.
The three metal spacers may tend to slide out during this
step. It this occurs, you may find it easier to lay the circuit
board assembly on the table and place the power supply half
of the processor module on top of it. Then turn the two halves
over together and align the screw holes. Also, make sure the
ribbon cable connector ejectors are closed.
Hand tighten the five assembly mounting screws. The two
shorter screws are screwed into the face plate. The three
longer screws are screwed into the cylindrical metal spacers.
Using a screwdriver, fully tighten the assembly mounting
screws.
From the top of the processor module, reconnect the ribbon
and power cables to their connectors on the main processor
