from Task %3
An attempt to free a block of memory was
unsuccessful because the header was
overwritten. The block of memory was
not returned to the free pool.
1. Save a fresh copy of the database to
your Maxum Workstation.
2. Connect to the SYSCON Debug port
with hyperterminal or equivalent with
‘save to file’ turned on.
3. Type the login and password individ‐
ually when prompted (maxum, maxum)
4. Type each of the diagnostic com‐
mands one at a time from the following

807 + Region 0 Memory Low: %3 The amount of free memory in the SY‐
SCON is low.
Verify the amount of memory installed
in the SYSCON. Contact Customer
Support.
808 + Excessive Network Com‐
munications
The internal network communication buf‐
fers (PNA buffers) are abnormally low.
This indicates that the network traffic to
the analyzer is abnormally high.
Investigate the cause of the high net‐
work traffic.
809 + System is excessively busy This is an overload situation, the process‐
or cannot keep up with the requests.
To reduce processor load:
● Reduce the size of the Modbus
table.
● Reduce the number and poll rate of
AIs and DIs.
● Reduce the number of concurrent
applications running.
● Reduce the communication burden
with Optichrom analyzers.
810 ? Invalid dbdat file The db.dat file, containing the 'cold' da‐
tabase on a Compact flash system, is
missing or invalid. This may happen if
the system was reset or powered down
during a user initiated save to flash (initi‐
ated from the HMI, CIM display, or the
workstation).
Perform a manual save to flash as soon
as possible in order to have a valid
db.dat file.
811 + Excessive Maxum broad‐
casts were dropped
Other analyzers on the network are gen‐
erating network broadcast messages at
an abnormal rate (greater than 200/min).
The excessive traffic is ignored. As a re‐
sult, the status of the analyzers in the an‐
alyzer table may not be up to date.
Investigate the network traffic. Contact
Customer Support for assistance.
812 ? Network communication
overload
The internal network communication buf‐
fers (PNA buffers) are full; the system
may not function normally.
Reset the device. Contact Customer
Support.
813 + SYSCON-SNE Comm De‐
bug: %3
Debugging information, for internal use. No action necessary.
814 ? Invalid CMOS time, check
the battery
The built-in SYSCON clock has an inva‐
lid time.
Check SYSCON clock battery and re‐
place if needed.
