Installation, Operation, & Maintenance
G & L Motion Control Inc. MMC Hardware Manual 11
Plus (MMC-A2 Plus and MMC-A4 Plus), as well as the Standalone Digital
MMC Control (MMC-D32 and MMC-D64), accepts up to four MMC Option
Modules.
Option modules are shipped with a 50-pin square post connector and screws
needed to attach the module to the MMC (or to another option module).
Follow the procedure below to add an option module to the MMC (or to
another option module).
1. Place the MMC and the option module on a static free surface. Ground
yourself using a properly grounded wrist strap before you begin. These
are standard precautions before handling any electronic components.
2. Remove the five screws securing the MMC cover using a #1 Phillips
screwdriver and set them aside. There are two screws on the top, two
screws on the bottom, and one screw on the side of the module.Lift the
side cover off and set aside.
3. Locate the 50-pin square post socket at the top of the MMC board.
Press one side of the 50-pin square post male connector into this socket
ensuring that the pins are aligned and it is firmly seated.
4. Pick up the option module. Line up the socket on the option module
with the male end of the connector extending from the MMC ensuring
that the pins are aligned. Press firmly into place. Be sure to align the
screw tabs on the top and bottom of the option module with the screw
slots on the top and bottom of the MMC module so that the modules
slide together easily.
5. Screw four screws (of the five included in your package) into the screw
tabs to attach the option module to the MMC.
6. Lay the unit on the bench. Place the cover you set aside in Step 3 on the
option module. Be sure to align the screw tabs on the top and bottom of
the cover with the screw slots on the top and bottom of the option mod-
ule.
7. Screw the five screws removed in Step 2 back into place to secure the
cover.
