Description
Note: If the function is not applicable, the display will read "-----"
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.
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.
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.
The main supply voltage is displayed.
