injection rate and limit values to that which was input by the operator.
4.7 Injection Light: This pilot lamp is on whenever the CO
2
controller is injecting CO
2
into the chamber.
4.8 Humidity Display: This digital display is marked %RH and indicates the relative humidity in the
chamber.
4.9 Datalog Communications Interface: This controller provides six (6) parameters to externally log
data of all the front panel displays. The MODE button is used to select the parameter, and the
UP/DOWN buttons are used to change the parameter's value.
4.10 Over Temperature Safety Control (OTP): Located front left of the control panel, this is a hydraulic
thermostat that is wired between the Main Temperature Controller and the heating element and
functions as an override control. If at any time the Main Temperature Control fails in the ON position
and the temperature in the chamber rises above its set point, the OTP is activated and maintains
temperature at its own set point. Note that the HEATING indicator will continue to function under the
control of the OTP.
4.11 Interface Ports: Located on the front left of the control panel opposite the Over Temperature Safety,
these three (3) ports are where the logged data can be externally accessed through serial and parallel
functions.
4.12 CO
2
Sample Port: This is located on the front left side of control panel. A sample can be drawn to
measure the CO
2
content in the chamber at this port.
