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.
