CIM-Base Removal and
Installation
Step Procedure
1. Before beginning replacement, if possible, save the current
Maxum .amd database file to be reloaded after the CAC3
board is replaced. Note that if the CAC3 is faulty, backup
may not function. In this case it will be necessary to use the
most recent backup file.
2. Once the database is saved, power off the Maxum.
3. Open electronic enclosure door (using a 4mm (5/32”) Allen
wrench if necessary).
4. Label and disconnect all cables from the CIM-Base and the
CAC3 mounted on the CIM-Base. This includes all cables
running to other devices in the Electronics Enclosure as well
as cables connecting to the CIM Display assembly.
5. Using a 5.5 mm wrench or nut driver, remove the 8 nuts that
secure the CIM-Base to the metal plate. These are located
around the edge of the board. Carefully remove the flat
washers from each stud as well.
6. Remove the CIM board from the plate. Verify that all switch
settings from the old CIM-Base and new CIM-Base match.
7. If the CAC3 is to be moved from the old board to the new
board, do so at this time. Install the CAC3 board on the new
CIM-Base by pressing it firmly into the connectors, taking
care not to touch any components or connections on the
board.
