same manner.
Figure 2 (opposite page) shows the Microcontroller
Board, Option Board and Power Supply Board.
To Add or Change Output Modules
The 500 Series units have provisions for four output
modules. The units come factory configured with
specified modules installed in appropriate locations.
You can make field modifications by properly remov-
ing and/or adding the modules into the appropriate
sockets.
Three of the output sockets are located on the Power
Supply Circuit Board. A fourth output socket is
located on the Option Board (refer to Figure 2).

and tie wrap hold
Output modules 1, 2,
and 3 (on the Power
Supply board) firmly
in place. To remove
the retention plate,
snip the tie wrap
with wire cutters
(Photo 5).
6. A disposable tie wrap
holds Output module
4 (on the Option
board) in place. To
remove the module,
snip the tie wrap
(Photo 6).
7. Inspect each module
before installation to
make sure the pins
are straight. Align
the pins with the
socket holes and
carefully insert the
module. Press down on the module to seat it
firmly on the board.

Pry apart these
retention clips gently
with a screwdriver to

from the front face
assembly (Photo 3).
Take care not to

scratch the circuit board.
The Microcontroller Board and Power Supply Board
remain attached to the Operator Interface Assem-
bly by wired connectors.
4. The Microcontroller
and Power Supply
board are attached
to either side of the
Option board by
male/female pin
connectors. Use a
gentle rocking motion
and carefully apply
