Description
The value of the main power frequency is displayed in Hertz. The frequency dis-
played will be halved if either fuse F1 or F2 is bad (alarm code AL21).
The ambient sensor reading is displayed.
Evaporator temperature sensor reading is shown on the right display.
Compressor discharge temperature sensor reading, using compressor dome
temperature, is displayed.
Reading for evaporator pressure transducer (EPT) is shown on the left display;
Press the ENTER key at Cd12 to show reading for compressor suction port pres-
sure on right display.
Compressor discharges pressure transducer reading is displayed.
This code displays the compressor motor hours. User can view unit run time by
pressing the ENTER key while in Cd16. Total hours are recorded in increments
of 10 hours (i.e., 3000 hours is displayed as 300).
The Compressor Motor Hour Meter display can be reset to 0 by pressing and
holding the ENTER key for 5 seconds. The Unit Run Time Hour Meter cannot be
reset.
Humidity sensor reading is displayed. This code displays the relative humidity,
as a percent value.
The software revision number is displayed.
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. "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.
This code indicates the dash number of the model for which the Controller is con-
figured (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. Val-
ues in "CFYYMMDD" format are displayed if the controller was configured with
a configuration card or with a valid OEM serial port configuration update; YYM-
MDD represents the publication date of the model configuration database.
The mode of operation is displayed (Unloaded - Standard - Economized).
The status of the compressor is displayed (OFF, On).
Displays the current evaporator fan state (OFF, LOW, HIGH).
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.W
Defrost temperature sensor reading is displayed.
