To observe if the system has experienced errors over a given period of time, you
can go to “View”, highlight “Message Log” and “Click” beside “Visible”. The following
example of the “System Message Log” has been enlarged to show details such as
description, severity and full date/time information. This example shows that an
FS20/25 System ran up to the fully operating condition, error free. If the system
continues to operate error free, there will be no changes made to this window. If
there are errors occurring, they will be displayed, along with an error code,
description of it and the time it occurred. The error checking process is much more
involved with the PC based system than with the previous MKI/MKII Processors. The
errors displayed can be “digital” in nature, which would indicate a fault between the
PC and PWR/TTM unit, or “analog” type faults, which would be a problem between
the PWR/TTM and head(s). The message logs themselves are saved to a file,
which can be downloaded to a floppy disk and forwarded by e-mail to a service
facility while the boat is at sea, to aid in fault diagnosis. This is considered one of
the primary system trouble-shooting tools.
