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 NU-Touch display the incubator the returns to the MAIN SCREEN and switches
to RUN mode.
8.9 Diagnostic and Checkout Procedures
The Incubator controller provides general diagnostic facilities:
• Diagnostic mode is intended for factory and field technicians.
It allows them to turn the controller's output signals (heaters, valves, safety devices etc.) on and off.
•
Diagnostics are located in the “Service Settings” menu categorized by the control systems (i.e. Temperature, CO2,
RH and O2) plus a general category for diagnostics not directly related to the control systems.
Press the “Diag” button to access them.
