Description
NOTICE
Note: If the function is not applicable, the display will read “-----”
Display Only Functions
- Cd01 through Cd26 are display only functions.
Cd01 Capacity Modulation
(%)
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
voltage components. It also measures current draw in compressor motor leg T3.
The compressor leg T3 current is displayed.
Cd04
Cd05
Cd06
Line Current, Phase A
Line Current, 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
control and diagnostic purposes. For control processing, the highest of the Phase
A and B current values is used for current limiting purposes. For diagnostic
processing, the current draws are used to monitor component energization.
Whenever 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
determine 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.
