EEV open 260%

[W.Miller]

Hi just a quick question, I have come across a chiller that has a electronic expansion valve open at 260% it's on a mcquay chiller, i've not really had much experience with the mcquay, is this valve defective

Is the valve open in percentage terms (%) or is it in pulse steps?

The joys of electronics.
The processor is possibly looking at suction Pressure and coil temperatures and a dozen other things and is indicating % of valve rated capacity, particually on pull down.
