When Replacing the New Controller Board (GDI)
There is no removable NV-RAM on the CTL board. When the controller board is replaced, it is
necessary to re-enter the information manually.
1. Do SP5-990-002 (SP) and SP5-990-003 (User Program) before you replace the controller
board.
2. After replacing the controller board, enter all the SP/UP data manually.
If you cannot print the SMC data lists, refer to the factory SMC lists, and enter the
values.
