Rajesh,

look up MKV diagnostic alarm (F:\Unit*\PROM\HELP_BD or QD) 273 - 277. It provides explanation & instruction for adjusting the IOMA power supply. Follow the instruction and the tolerance for best results.

You didn't mention what processor but having errors on <R> could indicate it's from <R> processor. Try adjusting the P5 pot in the power supply of that processor in slot 5 TCPS. Reset the errors on the processor. You don't use 335 volt sensors on 9E machine.
