YCAS0198 Chiller Current Transformer off wye delta locking out on a # 6 code "uncalibrated" Can't find explanation for this lock out. Texas Instruments 2ace-2c1 CAT. Number 1 circuit 164 amp fla 480v. All dip switches in correct position. Can not reset lockout. Never do exceed 104% lockout. Occasionally lock out "Low Current/mp/hp, but definately not a high pressure or motor protection issue. This SOB is driving me crazy! Any responce greatly appreciated. Oh bye the way someone installed a 100 ohm resistor on the +5 c resistor terminal on the CAT, I checked it out and it read 98. ohms. Thank you. If anyone can help me I will buy them a case of a beer!
