Maxum edition II Analyzer General Maintenance
Manual, August 2018, A5E42019842001
4.6 Alarm Codes, Descriptions, and Suggested Actions
Description
All PICs: A module temperature greater
than the defined maximum operating
temperature (default 65°C) has been de‐
tected.Overheating must be corrected as
soon as possible to avoid permanent
damage to the analyzer electronics, in‐
cluding reduced module life expectancy
or other board failures.
Note: This alarm can occur together with
alarm 1005 (Temp Diag Error) in which
case the board may not actually be over‐
heating.
This alarm concerns the temperature in
the electronics enclosure. This alarm is
not related to the Overtemp Shutdown
related to heater temperature controls.
All PICs: The state of the DO or the value
of the AO are locked and cannot be
changed. The AO or DO command was
ignored. Some DO and AO are locked
during a board self-test.

General Maintenance and Troubleshooting
Action
If the overheating condition is real, de‐
termine and correct the cause of high
operating temperature.
Possible causes include ambient tem‐
perature higher than specification or an
inoperative fan in the electronics enclo‐
sure (restricted air flow inside the EC).
When performing a board self-test, sus‐
pend all other operations affecting the
board.
