The mode display, on the ‘Main’ screen, is used to identify the mode of chamber operation: either standby or run.
In general, there is no need for operator interaction in "run" mode. However, operator interaction is required when
the incubator is first turned on then to perform calibration functions and address abnormal conditions status. If an
abnormal condition has, or does, exist for a particular parameter, an alarm becomes active and the ‘Alarm Status’
button will appear. This could be a catastrophic alarm condition, which could harm the tissue culture cells. It does
indicate an operational abnormality and should be checked. To acknowledge the abnormality, simply press the
“Alarm Status’ button to view the alarm, to dismiss it press the corresponding alarm’s button. The audio and visual
alarms will then extinguish. If the abnormality still exists, the return after waiting the specified alarm time.
Let the Incubator run normally, and if the alarm doesn't come back on, then everything is normal. If the alarm does
come back on, use the troubleshooting guide to correct the abnormality (see Section 11.0).
8.8 Standby Mode Operator Interactions
The NuAire incubator automatically enters the standby mode when necessary.
There is no action required by the user to enter this mode.
All functions that put the incubator in standby mode automatically start a 10 minute timer.
If the function is not interfaced through the screen on the NuTouch display, the incubator then returns to the MAIN SCREEN
and switches to RUN mode.
