Frequent Control.com forum member CSA created this check list for people who ask questions on the control.com forum. If you are looking for help to troubleshoot your GE Gas Turbine, give as much of the information asked for below that you can in your forum post. To post to the forum, go to [http://www.control.com Control.com].

=== Information required for troubleshooting GE-design heavy duty gas turbine issues: ===

# '''When did the problem begin?''' After a maintenance outage? After a forced outage (emergency shutdown, trip)? After a download of software or configuration to a Speedtronic panel?
# '''Provide a chronological list''' (including date/time) of all Process- and Diagnostic alarms:
#* That were active any time five (minutes) prior to the event (even alarms that have been active for days/months)
#* That were annunciated during the event
#* That were annunciated within one minute after the event
#:'''Don’t exclude Process or Diagnostic Alarms you believe are irrelevant''', and don’t just list the alarm you believe to be responsible for the trip (sometimes several trip-related alarms will be annunciated at the time of a unit trip, but only one of them—and not usually the LAST one to be annunciated—is the actual cause of the trip); let us make the determination of relevance.
# '''Tell us specifically what have you done to troubleshoot the problem''', including the results of the trouble-shooting (provide actionable information, like actual voltage values measured not just "checked voltages").
# '''What turbine control system is in use on the unit''' (version of Speedtronic (e.g., Mark IV, Mark V, Mark VI; Mark VIe; TMR, DUAL or SIMPLEX)?
# If the unit has a Mark V Speedtronic control system '''tell us which operator interface is in use with the unit''' (<nowiki><I></nowiki>, GE Mark V HMI running MS-Windows and CIMPLICITY, or ???).
# '''Tell us which Frame-size machine''' this problem occurred on (e.g., Frame 5, Frame 6B, Frame 6FA, Frame 9E, etc.).
# '''If the event is related to an emergency trip condition''', what was the load at the time of the event, what fuel was being burned, what was the average exhaust temperature, what were the exhaust temperature spreads, were any exhaust T/Cs failed or jumpered?
# '''Tell us what mode the unit was being operated in''', for example, Pre-selected Load Control, or Part Load, or External Load Control, or Base Load?
# '''If there was an electrical storm (lightning) or a frequency excursion prior to the event, describe it'''; if the unit was being operated at anything more or less than 100% TNH, +/-0.1%, provide the speed the unit was operating at when the event occurred.
# '''If the unit has DLN combustors, tell us the version of DLN combustor''' and what mode the system was operating in when the even occurred.
# '''If the unit has Wet Low NOx emissions reduction''' (Water- or Steam Injection for NOx reduction) '''tell us''', and indicate the actual flow-rate and required flow-rate.
# '''If the unit has Power Augmentation''' (Water- or Steam Injection) '''and it was enabled and in service at the time of the event tell us''', and indicate the actual flow-rate and required flow-rate.
# '''If the issue is related to transferring fuels''', particularly from gas fuel to liquid fuel, tell us when the last time the unit was operated on liquid, if anyone observed the Tell-tale Leak-off during the transfer and observed liquid fuel flowing out of the Leak-off, and what the individual pressures were from all of the positions of the manual selector valve downstream of the Liquid Fuel Flow Divider.
# '''If the issue is related to problems with starting on liquid fuel when the machine normally starts and runs on gas fuel''', tell us when the last time the unit was successfully operated on liquid fuel was, and when the last time the unit was successfully started on liquid fuel. Provide the individual pressures from all of the positions of the manual selector valve downstream of the liquid fuel flow divider during firing approximately 10 seconds after the liquid fuel stop valve, VS1-1, has opened and the Liquid Fuel Bypass Valve was commanded to close.

<big>'''Wiki Basics'''</big>

Wikis provide a way to share information, through articles written by users (that's you), and added to and edited by users (that's also you) over time. This page provides the basics as to how to use a wiki.

<big>'''Finding Stuff'''</big>

The typical way to find information in a wiki is to use the '''search''' box in the left column. If you're looking for, say, PID information, type '''PID''' in the search box and click on Search.

If a page with exactly that name is present, you'll go right to that page. If one or more pages with that term mentioned on the page exist, you'll see a list of relevant pages.

However, if no such page exists, you will see an invitation to create the page yourself. In fact, if you want to create a new page from scratch, searching for it is the way to start.

<big>'''Adding Stuff'''</big>

Anyone can create new pages, or edit existing pages on the wiki. HOWEVER, to do so, you must be logged in, for which you need an account (this is free). To set up your account, just click on the link in the upper right corner of the page labeled '''log in / create account'''. Fill in a username, password, your real name and email, and off you go.

Once you have an account and are logged in, you'll notice that every page (with the possible exception of certain pages which are "locked" by the administrator) will have a tab along the top labeled '''edit'''. If you click on that tab, you'll be able to edit the page and save your edits. Pretty simple.

As mentioned above, you'll also be able to create new pages. If you search for a page that doesn't exist (use the Go button, not the Search button), you'll see a link that will let you create a page on the topic you searched for. You can enter everything you know about it, and maybe try to get others to add their knowledge, too. That's how a wiki grows in usefulness over time.

<big>'''Talking about Stuff'''</big>

Finally, you'll notice another tab along the top of each page labeled '''discussion'''. This is a link to a special page, sometimes called the Talk page, that exists for each article page on the site, where people can talk about the content of the article page. The idea is that if you think the page needs to be changed, or feel that something is unclear, etc., you can post a message on the Talk (discussion) page, and maybe you'll get a response or maybe someone will edit the article to make it better.

The concept here is that there is an article page, and then there is a page to talk about the article, with the goal of making it better.

So, dive in, experiment, and we'll see what evolves. If you have any questions about how to use the wiki, feel free to ask us by using the [http://control.com/contact.php Contact Page on the Control.com forum].

= ControlWiki Article Guidelines =

Note: this page is under development - comments are encouraged on the discussion page.

== Noncommerciality ==

One of the primary principles upon which ControlWiki is based is noncommerciality in the content of the articles. Articles may mention specific products when relevant to the subject matter being discussed (for instance, program examples in the PLC Archive are encouraged to mention the platform for which they've been developed, unless they are purely generic RL or other common language).

Specifically excluded are articles extolling the virtues of a specific product or product line.

== Copyrights ==

No material should be published on ControlWiki except by the original author, or with clear written approval of the original author. We will immediately remove any articles upon learning that they were posted in violation of another's copyright. Refer to the [[ControlWiki:Privacy_policy | Privacy Policy]] for more information about copyrights on ControlWiki.

== External Links ==

Off-site links may be made to material of an instructional nature having direct bearing to the subject matter of an article. Spurious links to pages of a principally commercial nature will be removed. No links are allowed to sites offering pirated materials or to E-Bay or other sales-oriented sites.

== Images and Uploaded Files ==

Currently, only JPG, GIF and PDF files are supported for upload to the site, and must adhere to the content principles embodied on this page.

== Enforcement ==

The operators of ControlWiki reserve the right to be the final arbitrar of what material should appear on this site. Accounts may be removed and/or posting privileges suspended of those who repeatedly or egregiously violate the principles under which the site operates. Illegal activity may be referred to authorities of competent jurisdiction.

__NOTOC__
= Welcome to the ControlWiki! =

The ControlWiki is an encyclopedic store of information relating to industrial automation and control. It is written and maintained by its own users, people like you whose work is the automation of industrial processes. This is a place to share your expertise, contribute to a common body of knowledge, and otherwise strut your stuff.

== Visit the [[:Category:PLC Archive | PLC Archive]] ==
One portion of the ControlWiki we'd like to call to your attention is the [[:Category:PLC Archive | PLC Archive]]. This collection of contributed program examples is an educational resource, both for PLC beginners and for those who have a specific problem for which they would like a fresh approach.

== Disclaimer - Please Read ==
PLEASE NOTE: The maintainers of this site make NO representations about the accuracy of the information posted here. Please read [[ControlWiki:General_disclaimer | our disclaimer]] for more information. Honestly, your five-year-old kid could post something here. Use your head and don't bet your entire plant on something you read on the Internet. Duh.

== How to Use ControlWiki, How to Post Articles ==

The fastest way to get started here is to enter a search term in the box at left.

Posting articles is easy -- not much different from posting articles to any forum. We have a brief tutorial on how to get started on our [[Help:Contents | Help pages]]. Please familiarize yourself with the [[ControlWiki:Guidelines | Posting Guidelines]] before posting new content.

== Call for Authors ==

ControlWiki is inviting automation professionals interesting in contributing substantive articles to ControlWiki to contact us. Our publishing model is somewhat different from Wikipedia, in that a number of our feature articles on major automation-related topics will be attributed, single-author works.

The commitment we ask from a prospective author is to:

#Produce an initial article on the agreed topic in a timely manner.
#Monitor commentary on the article's talk-page.
#Update the article periodically, based on both changes in the state of the art and constructive suggestions made on the talk page.

If you have an interest, please contact us on our sister site, [http://control.com/contact.php Control.com].

{{PLC Archive

| author_name=Allen Smith
| program_filename=XAxisPLC.pdf
| abstract=An X-Axis motion control program for automating paint spraying.

This program controls a motor mounted to a plate which slides along a rail.

To reverse the direction of the motor, we used two pair of PLC relay outputs to swap the polarity of the voltage to the motor.

The speed of the motor is set by a potentiometer and viewed on a digital display.

A motor controller is used to send the motor 0-30VDC from a 30VDC power supply controlled by a 0-10VDC PLC analog
output signal.

Two limit switches(left and right) are used to stop the plate and then send it back the other direction.
