Description
Manufacturer General Electric (GE)
Manufacturing Location Salem, VA, USA
Part Number DS200TCEAG1A
Series Mark V
Product Type Emergency Overspeed Board
Instruction Manual GEH-6153
Board Location Protective Core <P1>
Features Signal Scaling, Protection
The DS200TCEAG1A is an Emergency Overspeed Board produced by General Electric Multilin for the Mark V series. Also called a Protective Processor, the board primarily works to safeguard the Mark V by making efficient use of the high speed protection circuitry.The Emergency Overspeed Board is also capable of bringing in signals for automatic synchronization, flame detection, low shaft speed, and high shaft speed. The aforementioned signals are scaled and conditioned, and then written to the STCA board over the IONET. TCEA boards can also send emergency trip signals to the TCTG (Turbine Trip Board); if enough relays “vote” to trip the unit, the TCTG board can handle this process.
The hardware configuration is straightforward when referencing the GEH-6153 user manual. Jumpers J31 and J1 located on the TCEA board are both used for testing purposes. The TCEA’s jumpers J4-J6 establish IONET addresses for the board. Jumpers J2-J3 provide for IONET termination resistors. J12-J21 jumpers help assign overspeed trip frequency settings, specifcally for the high pressure shaft. Meanwhile, jumpers J8-J11 and J22-J27 provide the same functions for the low pressure shaft. The hardware jumper screen and Appendix A both contain more information on hardware jumper settings. The user manual also has detailed information on the various other jumpers located on the board.
Frequently Asked Questions about DS200TCEAG1A
What is the DS200TCEAG1A? What is DS200TCEAG1A responsible for?
General Electric Multilin’s DS200TCEAG1A is an Emergency Overspeed Board (also called a Protective Processor) used for the high speed protection circuitry. DS200TCEAG1A is responsible for processing the overspeed and flame detection trip signals. DS200TCEAG1A works with <P>, the independent protective module.
What type of microprocessor does DS200TCEAG1A have?
DS200TCEAG1A has an 80196 microprocessor.
How is DS200TCEAG1A connected to the module?
DS200TCEAG1A is connected to the < P > core through a series of berg jumpers that program DS200TCEAG1A to the location in which it resides.
Users can assign the overspeed values and base speed for low and high pressure shafts through the IO Configuration Editor. After doing so, the IO Configuration Editor is able to automatically calculate the hardware jumper settings for trip frequency and select pulse rate information from the UV flame detectors. The tool can also choose auto-synchronization permissive values, reducing the amount of work for the user.
