4.6.2 Audio Alarm
To turn off, enable, or disable the audio alarm, display the Alarm Panel,
Tab to the Audio Alarm field, then Enter to toggle the option.
Note:
Even when the audible alarm is turned off, the back panel alarm output
will remain active.
Here is a list of the alarms and their meanings:
4-12
•
Overheat (not in Ambient version) is triggered if the read head ever
exceeds 220°C
•
•
•
Vapor: Vapor sensor detected a leak.
•
•
External: Back panel external alarm input is activated.
•
N2 pressure (not in Ambient version) is triggered when the temperature is set to less than 20°C, but the nitrogen pressure is less than
20psi. In this case, the alarm activates and resets the system temperature to 20.5°C. This prevents condensation from damaging the optics if
the nitrogen connection is not made, or if the tank runs empty.
•
Flow Cell temperature lock shows if the flow cell temperature is
locked
Leak: Liquid sensor detected a leak.
Recycle Open: Back panel recycle valve input requested the recycle
valve be actuated
Comet failed to actuate. This can occur when the cable is disconnected, or if the transducer needs replacement.
