ANALYZER OPERATING STATUS
STAND-BY
The analyzer is waiting for a user’s command (for example when the analyzer
is switched on after a shutdown), after single cycle analysis, or when the
operator has forced a stop in stand-by at the end of the current online / single
cycle by pressing the button previously activated a second time.
SINGLE
CYCLE
The analyzer is performing a single analysis cycle. As soon as the cycle is
completed the analyzer will go into the stand-by condition.
ON-LINE The analyzer is performing a continuous cyclic analysis based on the steps
set in the PROGRAM menu (Analysis Cycle) and started when the START
ON LINE button has been pressed. As soon as the analyzer completes an
analysis cycle, it will restart with a new analysis. This condition is identified as
the online condition.
MANUAL
STOP
The analyzer has been forced to stop. A message in the main menu shows
the “manual stop” and the fault alarm is initialized.
