Note: If the function is not applicable, the display will read “-----”
Display Only Functions
- Cd01 through Cd26 are display only functions.
Cd01
Digital Unloader
Valve Closed (%)
Displays the DUV percent closed. The right display reads 100% when the valve
is fully closed. The valve will usually be at 10% on start up of the unit except in
very high ambient temperatures.
Cd03
Compressor Motor
Current
The current sensor measures current draw in lines L1 & L2 by all of the high volt
-
age components. It also measures current draw in compressor motor leg T3. The
compressor leg T3 current is displayed.

Phase B
Line Current,
Phase C
The current sensor measures current on two legs. The third unmeasured leg is
calculated based on a current algorithm. The current measured is used for con
-
trol and diagnostic purposes. For control processing, the highest of the Phase A
and B current values is used for current limiting purposes. For diagnostic pro
-
cessing, the current draws are used to monitor component energization.When
-
ever a heater or a motor is turned ON or OFF, the current draw increase/
reduction for that activity is measured. The current draw is then tested to deter
-
mine if it falls within the expected range of values for the component. Failure of
this test will result in a Pre-trip failure or a control alarm indication.
Cd07
Main Power Voltage
The main supply voltage is displayed.
