Table 6-0: Main CPU Faults
Faults
Description
Possible Cause/Suggested Fix
FVARS Tbl
Chksum Err
Field Variables Table
Checksum Error. The
verification checksum
for the main field
variable table has
failed. During power
outages or brown-
outs, enough noise
can be generated on
the 5V DC supply to
cause an error in
reading the field
variables table on
power up. For this
reason, we keep the
data in two separate
tables. If only one
table checksum error
occurs, then valid data
will be restored.
• No action is required.
