    SRV Position in MarkV

    CSA, Thanks for the quick response. Out GT is Hitachi H25 (which is a compact version of Frame6) SRV/GCV is in one assembly similar to GE. Control system is Mark V I will try the procedure in the next shutdown. Meanwhile, as you mentioned, this negative 4.2% is normal and cannot be...

    SRV Position in MarkV

    SRV position at valve full close position was found negative 4.2% and LVDT voltage was 0.625V. we did calibration after adjusting LVDT to 0.7 v and auto calibration showed 0.2 %. After one day operation, when the unit was stopped the valve position again shows negative 4.2%. Actual valve...

    Alarm Printer

    > This sounds like a warranty issue. You should contact the supplier/packager for assistance. Yes CSA. But our system was installed and commissioned by M/S Hitachi (Gas turbines were supplied vy them) not by GE. Hitachis response to these issues are very poor. Can you advice?

    Upgrade from Mark IV to Mark VIe

    Dear CSA and Sanderson, We had the same issue after retrofit with MarkVie. I read your article. I solved the issue by providing rubber packing underneath flow divider legs while unit running on gas. Now the fql_pr1 signal level is almost zero and no more diagnostic alarms. Our flow divider...

    Flame scanner for MKVie control

    Thanks CSA, Honeywell flame detector is fine. But the issue is flame level is different in both scanners. One is 600 Hz and the other only 300 Hz on 75% load. This is the same in other Frame 5 unit also. What could be reason for this? How can we correct this.

    Flame scanner for MKVie control

    Thanks CSA. We have the conventional combustion chamber and Frame5 GT. Now we are retrofiting the control with MarkVie. But the flame scanners are the same. I was wondering does the same scanner will work in MarkVie. We have noticed that the flame detection is good on Natural gas fuel and...

    Flame scanner for MKVie control

    we are using honey well flame scanner P/N261A812P012 for MarkVIE. But this scanner is not good for diesel fuel operation. I believe GE recommends to use Geiger-Mueller scanner. Has anybody knows the Geiger-Mueller Part number for MarkVie flame scanner.

    GT Initial load

    Thanks a lot CSA. You are right. Operator can reduce the load after synchronisation. We did that and found unit is stable at 1.3 mW load. I tried to change LK90SPIN set to 1.5 MW. But setting reduce only to 2.3 MW. Then I reduced LK90PSMN from 2.5 MW to 1.5 MW. Then the setting reduced to 1.5...

    MarkV servo calibration

    CSA, You are right. The SRV must be passing. SRV and GCV are integrated one assembly. Ours is Hitachi H25 machine with MarkV TMR controls. I didn't change the values or adjusted lvdt. when srv is shut and gas valve open, P2 pressure rises. I had to reduce the purge timer, K2VG2Z from 3min...

    MarkV servo calibration

    After replacing the srv servo valve, we checked the LVDT voltages and found as 0.74 V at 0%. Actual valve position is also -0.1 % in HMI. In machine operation, srv passes even when it is in negative position (-2.1%) shown by the HMI value. I tried to put -10% value and got LVDT voltage as...
