1. Frame Size: 7EA 2. DLN System: DLN-1 Lo NOx 3. Gas Control Valves: Right Angle Fisher Valve EAB. On a side note, this unit always ran at a higher TTRF. We have 2050 (maybe its 2055) combustion parts. But at normal load, we would see 2040 while our other three units would get 2020ish...

The constants for the valve travel is .75 inches (if you need the markV signal name, I can look that up). If the system is thinking that the valve is opening/scaled to .75 inches but really only able to move/scaled to .72 inches, My gas valve is essentially opening more than it should based on...

The problem started showing itself again... Any I finally solved it. We started tracking a 4% error from the LVDT feedback (#1 and #2) to the reference point. It was made evident from an alarm on the HMI that appears when the comparison is 3% or greater from feedback to reference. Since both...

CSA, No problem providing the feedback, this site has helped me out many of times indirectly, it is time to repay the favor with my troubles. I was aware that TBQC on <R> did fan the regulators out to each of the units, however, the only TBQC card I had in stock I used on <S> core. Little...

I replaced TCQA and TCQC card today and it did NOT fix the issues with the auto calibration on Secondary Gas valve. I suspect that it may be an issue within the TCQA Prom Auto calibration program. I did what you said as well with the ribbon cables, that actually worked one time on another unit...

I appreciate the quick feedback. I try to research the best I can prior to posting. The MarkV Application/Maint GEH can only get you so far and after spending countless hours reading on Control.com about auto calibration on my iPhone in the PEECC with terrible service, it was finally time to...
