Description
Model number IS200ECTBG1ABB is one of the Excitation Contact Terminal Boards produced by General Electric as part of the Mark VI series. This model is one of the units within the first group of ECTB models. The two groups are ECTBG1 and ECTBG2. The IS200ECTBG1ABB model, as part of the ECTBG1 group, can only be used in redundant mode. Each board, no matter if in the first or second group of ECTB models, the board will contain two trip contact outputs, which will drive a customer lockout, as well as four Form-C relay contact outputs, controlled by an attached EMIO board. There are also auxiliary contact inputs, six in total, which will be wetted (powered) with 70 volts of direct current from the ECTB board. When being used redundantly, as this model will, the power will come from M1 and M2 power supplies.
Applications
Large power plants: GE EX2100/EX2100e excitation control cabinets in thermal, hydro, and nuclear power plants.
Heavy industrial energy centers: Self-contained power plants in steel mills and chemical plants.
Critical facility power supplies: Used to ensure stable excitation control of synchronous generators during grid connection.
Common Troubleshooting
Signal Feedback Error (52G/86G Loss):
Troubleshooting: Check the LED indicators on the terminal board to confirm whether there is a signal input when the external contacts are physically closed.
Cause: Mostly due to loose external wiring or a faulty fuse in the 70VDC wet voltage circuit.
Relay Not Operating:
Troubleshooting: Use a multimeter to measure the output terminals.
Solution: Confirm that the logic output in the control software (such as Toolbox) has issued commands. If the logic is normal but the relay does not operate, the onboard miniature relay contacts may be burnt or faulty.
False Alarm/Electromagnetic Interference:
Cause: High-voltage cables in the industrial field are too close to the terminal board.
Solution: Check the grounding status of the shielding cable to ensure that the signal line and power line are physically isolated.
Frequently Asked Questions
Q: What specific modules is the IS200ECTBG1ABB board used with?
A: The IS200ECTBG1ABB board can be used alongside EPCT, EXTB, and EACF Input-Output (I/O) terminal boards. It is managed by the EMIO board in conjunction with these modules.
Q: What are the 52G and 86G contact inputs on this IS200ECTBG1ABB model of PCB used for?
A: The 52G and 86G contact inputs are powered and monitored by the IS200ECTBG1ABB board with 70 VDC. The 86G input serves as a lockout input during normal operation, while the 52G input provides the proper online status of the attached generator.
Q: What are the four general-purpose Form-C contact outputs on the IS200ECTBG1ABB model utilized for?
A: The Form-C contact outputs are used for outputs such as 94EX and 30EX, among others. Each relay associated with these outputs requires a coil current, and the status of a relay auxiliary contact is also monitored.
