Stage 5 - The CPU Module
!
IMPORTANT: Observe Static Safe handling procedure.
To remove the CPU Module:
1 Disconnect the three ribbon cable
connectors (at the controller board
end) that link the CPU module with
the controller board.
2 Using a flat blade screwdriver,
remove the four screws from the
CPU module. Each screw has a
washer, ensure that the washers
are not mislaid.
3 Grasp the CPU module either side
of its circuit board adjacent to the
main connector at the top. Free the
board from the long connector with
small pulls on each side of the board.
When the connector becomes free,
remove the CPU module from its
mounting.
Note: The CPU Module and Controller
Board should be kept- and exchanged
together as a pair.
To fit the CPU Module:
1 Orient the CPU board so that its two
long edge connectors are at the top.
Place the CPU board close to the
controller board on the Starboard
side of the sensor.
2 Locate the three short ribbon cables
that lead from the middle section of
the controller board. In turn, attach
each of these cables to the corre-
sponding connectors on the CPU
module with their respective red-
marked wires uppermost.
Note:
ensure that the orientations of the
three short ribbon cables are correct
as it is possible to connect them the
wrong way round.
3 Ensure that the two long edge
connectors of the CPU board line up
with those on the controller board
and push the two boards together
so that they fully mate.
4 Insert four screws (each with a
washer) into the four holes of the
CPU board and into the correspond-
ing threaded mounting posts on the
controller board. Using a flat blade
screwdriver, tighten all four screws
to reasonable hand tightness.
