Limit Switches on Compressor Bleed Valve
dannys, Typically, the logic signals associated with 33CB-1 and 33CB-2 are l33cb1o and l33cb2o. The limit switches are usually wired to the normally open contacts, and the switches are actuated when the valves are closed--which means the contacts will be closed when the valves are closed. The...

Exhaust Thermocouples Flagging Red and Yellow
A LOT of sites never check their T/C wiring all the way from the exhaust JB to the Mark VI terminals. There are VERY specific ways T/Cs have to be connected to T/C extension wire, and if the unit weas provided by GE then special T/Bs are used and there are VERY specific ways T/C and T/C...

MOOG IGV actuator replacement
Have you contacted Moog directly? I just read Moog have opened an office/facility in India. It's not clear from your post if you're looking for a "rebuild kit" for the servo or the hydraulic actuator (double-acting cylinder) I've never heard of a "rebuild kit" for a servo, and certainly I...

Exhaust Thermocouples Flagging Red and Yellow
Basically, you're saying you believe that the Mark VI should be tripping the GE-design Frame 6 heavy duty gas turbine because the individual exhaust T/C bargraphs are turning red and yellow when the unit is at Base Load. GE, in their (not so) infinite wisdom (mistakenly) thought it would be a...

Hello Friend, Good Day. You haven't told what kind of turbine you are working on, and which Trip Card (TCTG; TCTS; or TCTL) is installed in Loc. 4 of the <P> core. You need to look at Appendix D, Signal Flow Diagrams, in GEH-6195, and find the drawing titled: "Emergency Trip Pushbutton...

MarkV Timers and Counters Inaccurate
sms, Sorry; I missed your last post. Thanks for the feedback! Congratulations for getting the download done. However, can you tell if the accumulators are incrementing properly now--even if the data values might not be correct? TOTD_Q.DAT is the Totalizer Data file. It is in Intel...

iffi08, As I know, it's impossible for us to know what, or how long, your experience is. I'm keenly aware of the language barrier, as well. In my advanced age, I'm also coming to realize that discussing something with one's staff is all well and good, but at some point in the process a...

GE Frame 9E Turning Mode Maximum Hours
glenmorangie, Once people get these ideas in their head about absolutely having to have the unit on cooldown for some minimum period of time before starting the unit (with flame and accelerating it to FSNL for synch and loading), it's just about impossible to get them to reconsider. Granted...
