Carrier CA Function Code


Code No Type Title Description
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 O2 Sensor Value (OS) Displays the percentage of oxygen in the gas flowing
through the oxygen sensor.
Cd09 Display CO2 Sensor Value (COS) Displays the percentage of carbon dioxide in the gas flowing through the carbon dioxide sensor.
Code No Type Title Description
Cd10 Display/
Cal
Time Elapsed Since Last Successful O2 Air Cal Displays the time that has elapsed since the last successful oxygen (O2) span calibration in hours/minutes (HHMM) format. Will also initiate an O2 air calibration when accessed, when the ENTER key is pressed and held for five seconds.
Cd11 Display/
Cal
Last O2 Gas Cal Date Displays the date of the last successful oxygen (O2) zero calibration in month/day (MMDD) format. Will also initiate a O2 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 O2 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.
Cd16 Display/
Reset
Hours Since Compressor Service Records total hours of air compressor run time. Hold the ENTER key for five seconds to reset to “0”.
Cd17 Display/
Reset
Hours Since Filter Change Displays the number of hours that have elapsed since the membrane air filters were changed. Records actual hours (ie. 100 hours is displayed as 100). Hold ENTER key for five seconds to reset to “0”.
Cd18 Display Total Run Hours Records the total number of operational hours for the air compressor of the CA system. Records total hours in increments of 10 hours. (i.e. 3000 hours is displayed as 300)
Code No Type Title Description
Cd19 Display Air Compressor State (AC) Displays the current operating status of the air
compressor (ON or OFF).
Cd20 Display Air Heater State (AH) Displays the current operating status of the air heater (ON
or OFF).
Cd21 Display Air Heater SSR PWM Valve (AT) Displays the current operating status of the PWM (Pulse Width Modulation) signal that is driving the air heater. The number displayed is a percentage of 100.
Cd22 Display Sample Air Solenoid Valve State (SAV) Displays the current operating status of the sample air solenoid valve (OPEN or CLOSED).
Cd23 Display Air Calibration Solenoid Valve
State (ASV)
Displays the current operating status of the air calibration solenoid valve (OPEN or CLOSED).
Cd24 Display Gas Calibration Solenoid Valve State (GSV) Displays the current operating status of the gas calibration solenoid valve (OPEN or CLOSED).
Cd25 Display N2 Sample Solenoid Valve State (NSV) Displays the current operating status of the nitrogen sample solenoid valve (OPEN or CLOSED).
Cd26 Display Oxygen Solenoid Valve State (OSV) Displays the current operating status of the oxygen solenoid valve (OPEN or CLOSED).
Cd27 Display Nitrogen Purity Valve State (NPV) Displays the current operating status of the drain solenoid valve -- #1 & #2 (OPEN or CLOSED).
Cd28 Display Drain Valve Solenoid State (DS1 and DS2) Displays the current operating status of the drain solenoid
valve -- #1 & #2 (OPEN or CLOSED).
Cd29 Display CO2 Input Solenoid Valve State (CSV) Displays the current operating status of the carbon
dioxide solenoid valve (OPEN or CLOSED).
Cd30 Display Door Lock Solenoid State (DIS) Displays the current operating status of the door interlock
solenoid (OPEN or CLOSED).
Cd31 Display/
Select
CO2 Concentration in Calibration Gas This feature gives the operator the ability to select the purity level of the CO2 gas being used for calibration. (5%, 20%, OFF)
Cd32 Display/
Select
CA Monitor Mode Monitor mode provides the ability to monitor CO2 and O2 levels while the atmosphere inside the container is not controlled. CO2 Zero and O2 Air Calibrations will be prohibited. (IN/OUT)
