to display past error history, each line displayed will be a possible clue to the
problem that caused the failure. If motor failures have occurred, the status will tell you which motor

11. Run Brewer Software.
Run the Brewer operating program by typing
BREWER  to check the correct operation of the
instrument. Select routines that you are familiar with and ensure that all functions and data appear
normal.
12. Replace Main Electronics Board
If no communications return when running Brewcmd then there may be a problem with the Main
Electronics Board.
Replace the Main Electronics board with a spare board, ensuring that all cables are reconnected to
the original connectors. Normally the spare Main Electronics board is preloaded with the same
parameters as those that came with the instrument. Therefore no reprogramming or uploading of
the configuration parameters are needed. If the configuration parameters have changed, then refer
to the procedure to upload new firmware and configuration data to the board, section 8.
The main board has a number of flat cables attached to it. The following lists the connectors for the
flat cables and the electronics they are connected with. “Top” (at the front) stands for pins 1-16.
“Bottom” (at the back) are pins 17-32:
