DESCRIPTION TITLE
Inapplicable Functions Display ----------
Cd13 Condenser Pressure
(CPC)
Condenser pressure is displayed using a pressure transducer. Pressure is
displayed in units of psig when code 28 is set to _F and units of bars when
function code Cd28 is set to _C. “P” is displayed after the value to indicate psig,
“b” appears after the value to indicate bars and “i” appears after the value for
inches of mercury.
Cd14
Compressor
Discharge Pressure
(Optional)
Compressor discharge pressure is displayed using a pressure transducer.
Pressure is displayed in units of psig when function code Cd28 is set to _F and
units of bars when Cd28 is set to _C. “P” is displayed after the value to indicate
psig, “b” appears after the value to indicate bars and “i” appears after the value
for inches of mercury.
Cd15 Unloader Valve
(On--Off)
The status of the unloader valve (if present) is displayed (on or off).
Cd16 Compressor Motor
Hour Meter
Records total hours of compressor run time. Total hours are recorded in
increments of 10 hours (i.e., 3000 hours displayed as 300).
Cd17 Relative Humidity
(%) (Optional)
This code is only applicable to units with a humidity sensor (HS). This code
displays, as a percent value, the relative humidity at that time.
Cd18 Software Revision # The software revision number is displayed.
Cd19 Battery Check
This code checks the Controller/DataCORDER battery pack. 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 and for alkaline batteries
with voltages greater than 7.5 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.
Cd20 Config/Model #
This code indicates the dash number of the model for which the Controller is
configured (i.e., if the unit is a 69NT40-511-105, the display will show 11105).
Cd21 Future Expansion This code is for future expansion, and is not in use at this time.
Cd22 Compressor Speed
(High--Low--Off)
The status of the compressor is displayed (high, low or off).
Cd23
Evaporator Fan
Speed
(High--Low--Off)
Displays the current evaporator fan state (high, low or off).
Cd24
Controlled
Atmosphere State
(On--Off) (Optional)
This code shows the state of Controlled Atmosphere (enabled or disabled), if
equipped.
Cd25
Compressor Run
Time Remaining
Until Defrost
This code displays the time remaining until the unit goes into defrost (in tenths of
an hour). This value is based on the actual accumulated compressor running
time.
Cd26 Defrost Termination
Sensor Temperature
The defrost termination sensor (DTS) is located immediately above the
evaporator coil. It is used by the Controller for defrost initiation and termination.
