6 HANDLING WARNINGS
When a system warning occurs, a warning message is displayed and the FAULT LED blinks. A
warning indicates that something in the system needs to be checked or adjusted. Failure by the
operator to respond to a warning may result in poor system performance and/or less accurate
data acquisition. Warnings should be taken seriously. See Section 4.13 for the gas alarms.
When a warning is displayed, the MSG and CLR buttons will appear on the menu line (when
not in setup mode). Pressing MSG will scroll through the warning messages if there is more than
one. CLR will clear the currently displayed warning message, and if there are no more warning
messages remaining, the MSG and CLR buttons will disappear and the FAULT LED will be
turned OFF. If after pressing CLR, warning messages still exist, the FAULT LED will continue
to blink and the MSG and CLR buttons will remain on the menu line.
If after clearing a message, the warning condition for that message still exists, the message will
reappear after a period of time which depends on how frequently the condition is checked by the
CPU (usually every few seconds). If a warning message reappears every time after CLR is
pressed, the problem should be solved and the analyzer restarted. Some problems may be
temporary and may not reappear after CLR is pressed (e.g. temperature too high, too low, etc.).
To ignore the warning messages and display the test measurement again, simply press TEST.
The warning messages will remain active and may be viewed again by pressing MSG.
