The number of faults, runs and door cycles are in hexadecimal. You can use the table
below to convert the value to decimal.
Match the first hex character in the value to the decimal equivalent in the first two
columns in the table; match the second character to the value in the next two columns; etc.
Then add up the decimal equivalents for all the values to get the decimal value.
In the example shown above, the number of faults is “0014”(hex). Using the table, this is
0 (1st char hex) = 0 (decimal equivalent from 1st two columns)
0 (2nd char hex) = 0 (decimal equivalent from 2nd1st two columns)
1 (3rd char hex) = 16 (decimal equivalent from 3rd two columns)
4 (4th char hex) = 4 (decimal equivalent from 4th two columns)
0014(hex) = 0+0+16+4 = 20(decimal).
The number of ru
ns is “135F”(hex), which is 4096+768+80+15=4959(dec)
The number of door cycles is “1619”(hex), which is 4096+1536+16+9=5657(dec)
After the number of days set in address $0401 (default is 60) the values from the current
Historical Log (addresses $0520-0527) are moved to the Previous Log (addresses $0528-
052F) and the current log is cleared out. The current date is loaded into the start addresses
for the new current historical log.
