Cd20 Config / Model Number This code indicates the dash number of the model for which the Controller is
configured (i.e., if the unit is a 69NT40-551-100, the display will show “51100”).
To display controller configuration database information, press the ENTER key.
Values in “CFYYMMDD” format are displayed if the controller was configured
with a configuration card or with a valid OEM serial port configuration update;
YYMMDD represents the publication date of the model configuration database.
Cd21 Capacity Mode The mode of operation is displayed (Standard - Economized).
Cd22 Compressor State The status of the compressor is displayed (OFF, On).
Cd23 Evaporator Fan State Displays the current evaporator fan state (OFF, LOW, HIGH).
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 Temperature
Sensor Reading
Defrost temperature sensor reading is displayed.
Configurable Functions - Cd27 through Cd37 are user-selectable functions. The operator can change the value
of these functions to meet the operational needs of the container.
Cd27 Defrost Interval (Hours
or Automatic)
This is the desired period of time between defrost cycles. Factory default is
“AUTO”. See Section 4.3.20 for information on Defrost Interval.
CnF11 determines whether the operator will be allowed to chose “OFF” as a
defrost interval option.
After a new Defrost Interval is selected, the previously selected Interval is used
until the next defrost termination, the next time the DTT contacts are OPEN, or
the next time power to the control is interrupted. If the previous value or the new
value is “OFF”, the newly selected value will be used immediately.
If any Auto Pre-trip sequence is initiated, Cd27 will be set to ‘AUTO’ unless
CnF49 (OEM Reset) is set to “Custom”.
Cd28 Temperature Units
(Degrees C or Degrees
F)
This code determines the temperature units (C or F) that will be used for all
temperature displays. The user selects C or F by selecting function code Cd28
and press the ENTER key. The factory default value is Celsius units. This
function code will display “-----” if CnF34 is set to F.
Cd29 Failure Action (Mode) If all of the control sensors are out of range (alarm code AL026) or there is a
probe circuit calibration failure (alarm code AL027), the unit will enter the
shutdown state defined by this setting. The user selects one of four possible
actions as follows:
A - Full Cooling (Compressor is on, economized operation.)
b - Partial Cooling (Compressor is on, standard operation.)
C - Evaporator Fan Only (Evaporator fans on high speed, not applicable with
frozen setpoints.)
d - Full System Shutdown - Factory Default (Shut down every component in unit.)
