CONTROL PANEL OVERVIEW (CONTINUED)
Main Control Panel Continued
Power Switch
The power switch controls all power to each workstation and its systems. Power is supplied when
the switch is in the ( I ) on position and illuminated.
Chamber Gas Light
This light illuminates when anaerobic mixed gas is being injected into the workspace chamber.
Incubator Display and Control
Labeled Set Temperature, this display shows the current air temperature in the incubation chamber
accurate to within 0.1

C. The arrow buttons can be used to adjust the temperature set point, or
place the display in its temperature calibration mode and then enter a display value correction.
The indicator light labeled Heating Activated illuminates whenever the temperature control system
is heating the incubation chamber.
Set Over Temperature
This graduated dial sets the heating cut off point for the OTL temperature limit system. The OTL
system prevents unchecked heating of the chamber in the event of a failure of the main digital
controller. For more details, please see the
Over Temperature Limit System description in the
Theory of Operations (page 35).
The red Over Temp Activated light illuminates when the Over Temperature Limit system cuts off
heating by rerouting power away from the heating elements.
Pass Box Doors Light
The clear Doors pilot light indicates that both pass box doors are closed. This light must be on in
order to cycle the pass box.
Anaerobic Light
This is light activates after the completion of a full auto cycle of the pass box Interior.
Aerobic Light
This light activates when the outer pass box door has been opened, exposing the pass box to
aerobic atmosphere. It remains on until the next completion of a full auto cycle.
Pass Box Pressure Display
This display shows the level of atmospheric pressure in the pass box, in inches of mercury (inHg).
At room pressure, the gauge should read at or close to 0. During cycles, the pressure in the box
should drop to -18inHg three times. At the end of an auto cycle the gauge should show a slight
overpressure in the box (approximately 0.5inHg).
