Country of Origin
This control board is engineered and manufactured by General Electric (GE) in the USA, specifically for the Speedtronic and Excitation system product lines.
Application Fields
The DS200LDCCH1AGA is a critical component in large-scale GE power conversion systems:
- Gas & Steam Turbine Control: Part of the Mark V Speedtronic system for regulating turbine auxiliaries.
- Industrial DC Drives: Managing high-horsepower motor controllers in steel and paper mills.
- Excitation Systems: Functioning within the EX2000 series for generator field control in power plants.
- Pulp & Paper: Synchronizing sectional drives for large-scale paper machines.
- Marine Propulsion: Integrated into electric ship propulsion drive cabinets.
Product Usage Instructions
- Safety Precautions: Ensure the drive or excitation cabinet is completely powered down. Warning: High-voltage DC capacitors may still hold a charge; verify with a voltmeter before proceeding.
- Configuration Check: Before installation, verify the EPROM version. The “H1AGA” version indicates specific firmware and hardware revisions. Ensure they match the existing system setup.
- Jumper Settings: Consult the GE hardware manual to set the onboard jumpers (e.g., JP1, JP2) for the correct LAN addressing and signal scaling.
- Board Replacement: Slide the board into the designated rack slot and secure it with the mounting screws. Use a grounded anti-static wrist strap to avoid damaging the CMOS components.
- Initial Power-Up: Upon powering up, monitor the 16-character LCD. If the board is functioning correctly, it will cycle through a self-test and display the “READY” or “RUN” status code.
Product Technical Description
The DS200LDCCH1AGA is essentially the “gateway” board for the drive. It uses a dual-microprocessor design to handle high-speed tasks simultaneously: one processor manages the local drive control loops (speed, torque, voltage), while the other handles high-level communication with the ARCNET or DLAN networks. This separation ensures that communication traffic does not interfere with the stability of the motor control. The board is “Enhanced,” meaning it features improved diagnostic capabilities and is capable of storing fault logs in its non-volatile EEPROM, which can be retrieved even after a power cycle for troubleshooting.
Q&A (Common Questions)
Q: What does the “H1AGA” suffix mean? A: This is a revision code. “H1” denotes the hardware group, and “AGA” refers to specific factory-installed firmware and minor hardware enhancements. It is vital to match these codes exactly for redundant systems.
Q: Can I update the firmware on this board? A: Yes, the firmware is stored in socketed EPROMs. If a system-wide update is required, the physical chips must be replaced.
Q: Why is the LCD display blank? A: This usually indicates a power supply failure on the board or an improperly seated EPROM chip. Verify the +5V and ±15V DC test points on the board.
Q: Does this board support Ethernet? A: No. This legacy board uses ARCNET or DLAN. For Ethernet connectivity, a separate gateway or bridge module would be required.
