CONTROL PANEL OVERVIEW (See Figure 2)
All controls are located on the front panel, except the over temperature safety which is
located in the back and the Door Temperature Controller which is located on the liner of the
outer door. Units with a detachable cord have a fused inlet located at the top rear of the
control panel. This inlet has a recessed male plug, fuse and an EMI filtering system
designed to filter out electrical interference. This inlet also prevents any internally
generated interference from feeding out to the power grid.
4.1 Power Switch: The I/O (ON/OFF) switch controls all of the power for the incubator
and must be in the I/ON position before any systems are operational. Both
temperature and CO
2
displays will illuminate when the power switch is in the ON
position.
4.2 Water Low Light: This pilot lamp is on whenever the internal water jacket float
switch has been tripped to the closed position. When the water drops low enough
the float switch closes the circuit turning on the indicator light.
4.3 Safety Activated Light: This pilot lamp is on whenever the Over Temperature
Safety thermostat has been activated and taken control of the element. During
normal operating conditions this indicator should never be on.
4.4 Main Temperature Control: This controller is marked C° and indicates the actual
temperature within the chamber to .1°C. The UP/DOWN buttons are used for
imputing the set point, calibrating the display, and muting or unmuting the audible
alarm. The HIGH and LOW alarm indicators will light whenever there is an alarm
condition associated with the temperature within the chamber. The MUTE indicator
will light whenever the audible alarm has been deactivated.
4.5 Heating Light: This pilot lamp is on whenever the Temperature Controller is
activating the heating element.
4.6 C02 Control On Water Jacket Incubators: The control sets the rate and the
limit of injection of CO2 into the incubator based on input value and some
variables. The input value is set by the operator. This is set at 5% CO2 in
production. The variables are the amount of humidity in the chamber, and the
amount of time the control has been trying to inject CO2.
At start-up, the incubator must be warmed up to operating temperature. This is
set in production 37°C. During warm up, the water tray for humidity should be
filled and placed inside. This allows the humidity to reach 95% before CO2 is
