Brian, Could you tell us how you can access the zoom feature? Many sites don't have the CIMPLICITY toolbar at the top of the display, and lots of people don't know how to make the Toolbar visible. Is there a hot-key sequence that can be used to zoom in--and out? Is this a CIMPLICITY...

sherif elzoghby, As has been said many times on control.com: It's virtually impossible to say for certain precisely how your machine would respond to specific conditions without being able to see the application code running in the Speedtronic panel at your site. Further, if the turbine...

Prasad, Most GE HMIs were shipping with a back-up utility called Acronis True Image (or some version of Acronis)--which works very well. It can be used to entirely back-up the hard drive to removable media (CD, DVD, etc.) even spanning multiple discs for a single hard drive. This is the...

Have you asked the installer? I believe the only method is to change display resolution, unless you manually edit every display. So, you would have to use the MS-Windows Control Panel Display applet, or the display card driver utility on the HMI CPU to decrease the resolution. Just be...

To Brian's point, we could tell you the typical things to force and do, but we don't understand what you're trying to do (what is the purpose of the IGV test?) and we don't know enough about your machine (does it have an Aux. Hyd. Pump, or does it have to be CRANKed to develop hydraulic...

Brian Hall, Adjusting the null bias spring on the servo-valve is just <b>begging</b> for trouble. The Control Specification has procedures for calculating the null bias current setting--but in my experience it's almost never required to adjust the null bias from 2.67% (per processor in a...

Brian Hall, I completely missed your response; sorry. For ABB to do what they're saying, they would have to have an EGD to OPC "converter"--and while that's possible for data points, it won't get you alarms and events which are handled in a completely different scheme (by WorkstationST...

Neo, You are reading the Longname description for LCRPERR very literally--and that can be a mistake sometimes. As we've learned. If that logic signal has a rung, can you post it? Your sentence for L3STCK3 is correct. And you are also right: L4T is VERY important (we're headed there...

Bruce Durdle, Dear, oh dear, oh dear, my mistakes were: 1) I did (do) consider MVA to be "power"--specifically "total power", since that's the amount of "power" being produced (both real and reactive). I keep forgetting about the "apparent power" thing. In my mind if I operate a...

Neo, Sorry, I missed your post. I also believe that the unit you are operating may be burning more than one gas fuel, based on some of the logic signals in the post (_IP--Inert Purge, for one). You didn't tell us about that. Give me some more time to review your post.

chudy, Have you used the Trip History Display to determine what the cause of the trip was? It was most likely the transformer lockout, NOT the cooling water pump motor. MOST everything that trips the turbine does so through the L4T rung, and it's various sub-rungs (L4PRET, L4POST, L4PST...

csa, The indicated position (from the calibrated LVDT feedback) when the turbine is running seems to be reasonable (presuming the turbine is not 100% loaded). The SRV should not be 100% open (because it's trying to control P2 pressure upstream of the GCV) and the GCV should, typically, be at...

csa, (interesting choice of moniker) Diagnostic Alarms can be seen for various cards (the VSVO in this case) using Toolbox. The feedback can be seen from the LVDTs using Toolbox (it's not always easy to find, but it's there). If you are referring to the problem of the SRV LVDT feedback...

Bruce Durdle, Thanks; once again I was hoping for your input and clarification. It's greatly appreciated--and respected.

ABDI, Because, the transfer passages/nozzles are part of the secondary fuel nozzles. If the DLN-I combustion system on the turbine at your site uses a Gas Transfer Valve, if you follow the fuel line from the Gas Transfer Valve to the manifold around the axial compressor casing and then...

ABDI, The transfer pipes and internal "holes" of the secondary fuel nozzles can be called "passages" because they pass gas (no pun intended).

Phil Corso, I'm sure I would flunk your class, or more likely be expelled. Thank your student for the tutoring option--if he/she actually offered. My understanding of electricity is adequate for my needs--and those of my Customers/colleagues, even though it doesn't meet your standards or...

I agree with d; this isn't all that uncommon. I doubt that it's caused by the wires inside of the shield, unless they are constantly carrying a fair amount of current. Where is the shield drain wire grounded? It should be grounded at only one end of the cable--and by default, that is usually...

Kurt Lammrish/Mike West, Yes, this problem does seem to be on-going for some sites, and a PROM upgrade does seem to solve the problem for some sites but not for others. The DENET connects <C> to <R>, <S>, and <T> and when this problem occurs it does, for some odd reason, seem to affect <R>...

Phil Corso, Why is it so hard to just answer a question with an answer? Even if you have to provide more information than requested because the original poster didn't provide enough information. You seem so eager to use unexplained terms, inconsistent significant figures, and now semantics.
