I see in LED Panel, Measurements of Input voltage-216 219 217,Measurements of Output voltage-230 229 230 and in Alarm-Bypass Phase Rotation.
SOURCE: alarm: bypass phase rotation, What is it?
it indicates you have a polarity issue on your bypass feed. Most likely L1, L2 or L3 are mixed up (rotated). So you are using L2 as L1 or something like that. You should check (measure) the phase rotation/polarity.
