Handle alarms
The [Alarm monitor] screen displays up to four alarms.
When more than four messages are generated, press <Alarm Trace> on the
[Tools] screen to print the alarm codes and the times at which they occurred.
When the analyzer is switched on and in Stand-by status, any displayed alarm
must be checked, solved and cleared before next samples are processed.
If any errors have occurred during the setting of parameters, the message does
not appear until <Start> is pressed.
If the analyzer comes to an emergency stop due to an error, execute the reset
function on the [Maintenance] screen after resolving the alarm cause.
Alarm levels
The main alarm levels are WARNING, S.STOP, STOP, and E.STOP.
WARNING Although this warning is issued, the analyzer continues to measure samples.
After completion of the current sampling, check the alarm condition, and take
the action outlined.
S.STOP Only the sampling sequence is stopped. For samples in process, measurement
continues and the result data are generated. Check the alarm condition, take
the action outlined, and restart the operation.

samples in process, measurement, result data printing and host
communication stop immediately. Check the alarm condition, and take the
action outlined. Check the results for the last samples that were processed
before the alarm message appeared. Reset all samples that were processed but
not measured/ printed/ sent to host and repeat the processing of these
samples.
E.STOP The analyzer stops instantly (15-second instrument cycle is NOT finished).
For samples in process, measurement, result data printing and host
communication stop immediately. Check the alarm condition and take the
action outlined. Execute the reset function on the [Maintenance] screen after
resolving the alarm cause. Check the results for the last samples that were
processed before the alarm message appeared. Reset all samples that were
processed but not measured/ printed/ sent to host and repeat processing of
these samples.
