CONTROL PANEL OVERVIEW (CONTINUED)
Temperature Control and Display Panel
Labeled Set Temperature °C, this panel comes with a green digital display that shows the air
temperature in the incubation chamber, accurate to 0.1°C. The display can also show the user-
selected temperature set point, as well as display-adjustments during calibrations. The controls
consists of an UP / DOWN arrow pad for inputting a temperature set point, muting active
temperature deviation alarms, and performing calibrations. Red LED alarm indicators marked HIGH
and LOW illuminate whenever temperature deviations of ±1°C or greater from the current set point
are detected. The yellow LED marked Mute illuminates whenever an audible alarm is being muted.
See the
Muting the Audible Temperature Alarm entry on page 28 of the Operations section for
more information.
The green LED indicator labeled HEATING ACTIVATED illuminates whenever the incubator
temperature control system is heating the incubation chamber.
CO
2
Control and Display Panel
Labeled Set CO
2,
the display on this panel shows the concentration of CO
2
in the incubation
chamber as a percentage of the chamber atmosphere, with a range of 0% to 20%. During the
automatic decontamination cycle this display shows messages alerting the user to which stage of
the cycle the unit is in, as well as a timer countdown while in the two-hour heat soak stage. The
panel can also show the CO
2
set point, as well as display-adjustments while in gas calibration
mode.
The UP / DOWN arrow pad on this panel is used to input a CO
2
concentration set point for the
incubation chamber, mute active gas deviation alarms, and to enter calibration corrections. Red
LED alarm indicators marked HIGH and LOW illuminate whenever CO
2
deviations of ±1% or
greater from the set point are detected. The yellow LED marked MUTE illuminates whenever an
audible deviation alarm component is being muted. See the
Muting the Audible CO
2
Alarm entry
on page 32 of the Operations section for more information.
Marked CO
2
INJECTING, this green LED indicator illuminates when the incubator is injecting CO
2
into the incubation chamber.
Decontamination Cycle Panel
This panel is used to initiate or abort the automated decontamination cycle. Its controls also lock
and unlock the door prior to and after the cycle. Unlocking door after completing or aborting the
cycle restores the system to its normal operations mode. The panel is also provided with LED lights
that indicate what stage of the cycle or cycle-abort the incubator is in.
