D. Type readlog 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
and what the failure is. Usually it is a sensor problem or a wiring problem that prevents the motor
from resetting. If no problems are displayed, then the system can be placed back into cosmac
mode for further testing.
E. Type loadmode and following the return of the prompt, type cosmacmode . The motors
will reset and within a minute the system will display the status that it is in cosmac mode.
F. Quit the Brewcmd program by typing quit .
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:
J2 top BA-W77/A Lamp Board
J2 bottom BA-W77/B J1 on hv module
J13 top BA-W76/B iris
J13 bottom BA-W76/A zenith
J14 top BA-W76/B fw #1
J14 bottom BA-W76/B fw#2
J15 top BA-W76/A micrometer #2 (MKIII only)
J15 bottom BA-W76/A micrometer #1
J16 bottom BA-W76/C fw#3 (MK IV only}
J17 top BA-W76/B slitmask (shutter)
J17 bottom BA-W76/A azimuth
J12 top BA-W76/A control switch’s
J7 top Communication
J7 bottom humidity sensor
