9.1.4 CA Controller Function and Data Codes
There are functions which the operator may access to
examine the operating status of the unit. To access
these functions, perform the following steps: Press the
CODE SELECT key, then press an ARROW key until
the left window displays the desired code number (see
Table 21). For the display-only function codes, the right
window will display the value of this item for five seconds
before returning to the normal display mode. If a longer
display time is desired, pressing the ENTER key will
extend the time to 30 seconds after the last pressing of
the ENTER key. Below is an explanation of all Function
codes.
Table 22. CA Controller Function Code Assignments
CODE TYPE TITLE DESCRIPTION
Input Codes
Cd01 Display Membrane Temperature Setpoint
Displays the temperature set point for the nitrogen
membrane separator that was set during configuration.
Cd02 Display
Membrane Input Temperature
(MTS)
Displays the temperature of the air entering the nitrogen
membrane separator.
Cd03 −−−−− Future Expansion
This code is for future expansion, and is not in use at this
time.
Cd04
Display/
Select
Temperature Units
This code determines the temperature units (_C or _ F)
which will be used for the CA display module. The user
selects _C or _F by selecting code 04 and pushing the
ENTER key. The factory default value is _C. This code
also effects pressure units, i.e., bars or psig.
Cd05 Display Software Revision The software revision number is displayed.
Cd06 −−−−− Future Expansion
This code is for future expansion, and is not in use at this
time.
Cd07 Display
Nitrogen Supply Pressure
(MPT)
Displays the pressure of the nitrogen membrane
separator.
Cd08 Display O
2
Sensor Value (OS)
Displays the percentage of oxygen in the gas flowing
through the oxygen sensor.
Cd09 Display CO
2
Sensor Value (COS)
Displays the percentage of carbon dioxide in the gas
flowing through the carbon dioxide sensor.
Service Codes
Cd10
Display/
Cal
Time Elapsed Since Last
Successful O
2
Air Cal
Displays the time that has elapsed since the last
successful oxygen (O
2
) span calibration in hours/minutes
(HHMM) format. Will also initiate an O
2
air calibration
when accessed, when the ENTER key is pressed and
held for five seconds.
Cd11
Display/
Cal
Last O
2
Gas Cal Date
Displays the date of the last successful oxygen (O
2
) zero
calibration in month/day (MMDD) format. Will also initiate
a O
2
gas calibration when accessed, and the ENTER key
is pressed and held for five seconds.
Cd12 Display CA Locked Out By Reefer
Will display a “YES” or “nO”, indicating if the Temperature
(refrigeration) Controller is causing the CA Controller to
not operate.
Cd13 Display
Last O
2
Span Calibration
Voltage in mV
Displays the last oxygen span calibration voltage in
millivolts.
Cd14 Display Oxygen Sensor Life
Displays the current operating status of the oxygen
sensor (OS), “good” or “bAd”.
Cd15
Display/
Test
Battery Test
This code checks the internal battery. While the test is
running, “btest” will flash on the right display, followed by
the result. “PASS” will be displayed for battery voltages
greater than 7.0 volts, “FAIL” will be displayed for battery
voltages between 4.5 and 7.0 volts, and “−−−−−” will be
displayed for battery voltages less than 4.5 volts. After the
result is displayed for four seconds, “btest” will again be
displayed, and the user may continue to scroll through the
various codes.
