Hi Control.com team,

We have a number of GE Frame 5 gas turbine and Mark 2 control system schematics and electric drawings. The drawings are typically from late 1970s and 1980s, does anyone know what standard GE used for the drawing symbology or legend?

Trying to confirm what the symbols they used for items like thermal overloads, fuses, and various electrical components, was hoping someone may have a legend or key diagram that shows what the symbols represent please!

Kind Regards,

Byron.

Packager was GE. Any help you can provide would be greatly appreciated.

 

@Byron Mills,

Have you looked through the Operation & Maintenance Manuals provided with the machines?

If I recall correctly GE published something called a Mark*II SpeedTronic Control Diagram Reading Aid that should be very helpful with understanding the Mark* II equipment drawings and the SpeedTronic elementary drawings.

GE also released the "backsheets" *(printed wiring boards (or printed circuit cards) schematic diagrams) for all of the DOM (Direct-O-Matic) cards used in the Mark* II SpeedTronic turbine control panel which were VERY helpful in diagnosing problems and even some minor repairs. If the site has several Mark* II SpeedTronic turbine control panels I would be very surprised if the site never obtained the backsheets for trouobleshooting and maintenance. There were tens of backsheets for all the different DOM cards that were produced and used.

Have a look at the Operation ^Maintenance Manuals (the backsheets won't be there, unfortunately) but the Reading Aid document/publication should be.
