Peak value alarms
Peak value alarms do not impact the system status alarm dry contact output.
•
Alarm 1 peak #
When the concentration of impurity is greater than the Alarm 1 for the peak.
•
Alarm 2 peak #
When the concentration of impurity is greater than the Alarm 2 for the peak.
•
Overscale peak #
When the concentration of impurity is greater than the actual scale of the
peak.
3) Peripheral alarms:
Some peripherals connected with the analyser may show their alarms/errors
status in the
Historic Alarm
menu. Refer to their User Manuals for more
information.
When a problem arises, a new alarm is generated and the button of the
HISTORIC ALARM
menu
turns red. If the menu is opened and an alarm is
still active, it turns yellow. If another alarm occurs, it turns red again. The
button will turn green when all alarms are resolved.
Every system alarm will activate or deactivate the system status alarm dry
contact output, depending on the settings in the
CONFIGURATION
ALARM
menu. Peak value alarm 1 and 2 each have a separate dry contact
output that is activated or deactivated, depending on the
CONFIGURATION
ALARM
menu, when the alarm thresholds are reached.
Some system functions, such as a real-time chromatogram, are disabled when
alarms are active. Rectify the problems before proceeding with your analysis.
When the problem is resolved, the same alarm message is displayed, but with
an “Ok” message (except for a “Plasma shut down” that is resolved with a
“Starting” and for the “Plasma OFF” that is resolved with a “Plasma ON”).
Example:
• If a “Low carrier flow” occurs, the following message is displayed:
(date) Low carrier flow: (hour)
• When the flow problem is rectified, the following message is displayed:
(date) Low carrier flow: Ok (hour)
