8.5 Rear Panel Detail
The rear control panel contains the following functions BCD-09440.
8.5.1 Power Cord
The power cord is 8-foot (2m) in length, type “SVT” molded plug, allowing for long life and easy
cleanability.
8.5.2 Circuit Breaker
All control electronics are protected with a circuit breaker that may trip at 110% of load rating,
but will trip at 145% of load rating in less than 2 seconds. Should the circuit breaker open pop-
out button will appear, merely depress to reset.
8.5.3 CO
2
Inlet
The CO
2
inlet provides a fitting for vinyl tubing. Be sure to follow the recommended inlet
pressure to insure proper flow rates and consistent CO
2
percentage readings.
8.5.4 Power Switch
The power switch, located at the top of the rear panel, controls all power to the incubator.
8.5.5 Internal Tank Switch Option
The internal tank switch is an option, which is customer installed in the field, or at the time of
manufacture. The tank switch performs the critical back-up function of switching tank 1 and tank
2 and back again when each depleted tank is replaced.
8.5.6 Communication Interface/Alarm
Two receptacle connectors are provided for direct field connection of a computer/printer and a
remote alarm indicator.
8.6 Run Mode Operator Interactions
The mode switch is used to select the mode of chamber operation: setup or run.
The chamber operation mode is changed by pressing the run/setup key for three seconds. The mode
switch LED will display a green light when in run mode.
In general, there is no need for operator interaction in "run" mode. However, operator interaction is
required to perform calibration functions and abnormal condition status. If an abnormal condition has, or
does, exist for a particular parameter, a blinking green LED next to the parameter will be lit. 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 mode
switch to setup and back to run to clear the system. The blinking green LED will then extinguish. If the
abnormality still exists, the blinking green LED will again be lit.
Let run normally, if the blinking green LED doesn't come back on, everything is normal. If the blinking
green LED does come back on, use the troubleshooting guide to correct the abnormality see Section 11.0.
8.7 Setup Mode Operator Interactions
The chamber operation mode is changed by pressing the RUN/SETUP key for three seconds. The mode
switch LED will display a green and blinking light when in setup.
