Description
Product Description
The DS200PLFMG1A is a General Electric Mark V DS200 Phase Logic Fault Board used to monitor phase-related hardware fault status in compatible GE drive and turbine control equipment. The PLFM board monitors three phases—A, B, and C—with six status LEDs assigned to each phase. The indicators correspond to Upper Gate Drive 1, Upper Gate Drive 2, Lower Gate Drive 1, Lower Gate Drive 2, Overcurrent 1, and Overcurrent 2. A separate green power LED provides board power indication. The related assembly identifier DS200PLFMG1AAA belongs to the same PLFM family and should be matched carefully when replacing an installed board.

Functional Features
- Provides phase-level hardware fault status indication for compatible Mark V DS200 equipment.
- Monitors Phase A, Phase B, and Phase C sections independently.
- Each phase provides six dedicated LED indicators.
- Indicates upper and lower gate-drive fault conditions.
- Provides separate overcurrent status indications for each phase.
- Includes a dedicated green power LED for basic board power verification.
- The PLFM board is designed for maintenance and fault-status monitoring within the Mark V control cabinet.
- The DS200PLFMG1AAA assembly has three visually separated phase sections labeled Phase A, Phase B, and Phase C, with the six red status LEDs in each section.
FAQ
Q: What is the DS200PLFMG1A used for?
A: It is a Mark V Phase Logic Fault Board used to display phase-related gate-drive and overcurrent fault status.
Q: How many phases does the PLFM monitor?
A: The board monitors three phases: A, B, and C.
Q: What does each group of six LEDs indicate?
A: The six indicators correspond to Upper Gate Drive 1, Upper Gate Drive 2, Lower Gate Drive 1, Lower Gate Drive 2, Overcurrent 1, and Overcurrent 2.
Q: What is the difference between DS200PLFMG1A and DS200PLFMG1AAA?
A: They are closely related identifiers within the PLFM family. DS200PLFMG1AAA is identified as a Phase Logic Fault Module assembly associated with the DS200PLFMG1A board. Match the complete marking on the existing hardware before replacement.
Q: Is this board a standalone controller?
A: No. It is a system-level fault monitoring and indication board intended to operate as part of compatible GE Mark V equipment.
Q: Can another PLFM revision be substituted directly?
A: Do not assume direct interchangeability. Verify the complete part number, revision, connector arrangement, and host-system configuration before installation.
Troubleshooting & Safety
- Confirm the complete DS200PLFMG1A / DS200PLFMG1AAA identification before replacement.
- Compare the connector arrangement and PCB markings with the original board.
- If the power LED does not illuminate, verify the associated control power and board connections before replacing the PCB.
- If only one phase shows a fault indication, inspect the corresponding gate-drive and overcurrent circuits before assuming the PLFM itself is defective.
- Record the original wiring and board position before removal.
- Inspect the connector and mating cable for bent pins, contamination, or loose connections.
- Do not treat an illuminated fault LED as proof that the PLFM board itself has failed; the indicator may be reporting a fault originating elsewhere in the drive system.
- Use appropriate ESD protection when handling the exposed PCB.
- De-energize and isolate the associated drive/control cabinet before removing or installing the board.
- DC bus and control circuits may retain hazardous voltage after shutdown. Follow site lockout/tagout procedures and verify safe voltage before servicing.
- Match the replacement revision and system configuration before returning the equipment to service.
