About the DS200PLFMG1A
The DS200PLFMG1A model is described as a Phase Logic Fault Model (PLFM). This unit was made to be used with other Mark V DS200 models from General Electric. The Mark V Series that this DS200PLFMG1A printed circuit board belongs to is describable as a Speedtronic Mark Series product, as its Mark V Series exists as one of the final General Electric Mark product series to make use of the company's Speedtronic control system technology first introduced alongside the conception of the Mark I Series in the late 1960s. This DS200PLFMG1A printed circuit board or PCB for short is also considered to exist as a now-obsolete legacy series General Electric product, due to its placement in the Mark V Series which has been discontinued for manufacture in the years following its initial release. This DS200PLFMG1A device is also not considered the original Phase Logic Fault Model introduced to the Mark V Series; that would be the DS200PLFMG1 parent printed circuit board missing this DS200PLFMG1A PCB's A-rated functional product revision.
Hardware Tips and Specifications
As a now-obsolete Mark V Series product with a noted lack of internet-available instructional manual materials, this DS200PLFMG1A PCB benefits well from its possession of a factory-formulated DS200PLFMG1A functional product number that identifies many of its more-basic hardware component inclusions and specifications. The DS200PLFMG1A functional product number begins with the DS200 series tag delegating this DS200PLFMG1A PCB's normal Mark V Series assembly as well as its domestic location of original manufacture. This is followed in the DS200PLFMG1A functional product number by the PLFM functional abbreviation, which itself is followed by another dual-functional naming component in the G1 series grouping tag describing the DS200PLFMG1A board's normal PCB coating style and group one Mark V Series product grouping. The final A digit at the very end of the DS200PLFMG1A functional product number describes this DS200PLFMG1A PCB's A-rated functional product revision.
When operated with the Mark V DS200 drive,the PLFM is used to indicate the status of the phases. There are three phase identifiers named phases A, B, and C. Each of the phases has six LEDs. The six LEDs in each of the sections are as follows:
- Upper Gate Drive 1
- Upper Gate Drive 2
- Lower Gate Drive 1
- Lower Gate Drive 2
- Overcurrent 1
- Overcurrent 2
Each of the LEDs is vital when operating the DS200PLFMG1A model as it will help understand how the remaining boards with the Mark V DS200 cabinet are operating. Unfortunately, due to a lack of documentation for the PLFM model, it is unsure how the LEDs will respond to the model and what they will look like when indicating potential faults. Underneath all of the phase LEDs, there is one small power LED that lights up green when power is connected to the PLFM unit. There is only one connector available on the DS200PLFMG1A model. This connector is located on the short edge of the PLFM unit and is a twenty-pin connector. Once again, due to the lack of documentation, it is unknown what type of connector is used to attach this card to the other Mark V DS200 units or how it will be mounted alongside the drives or boards in the Mark V cabinet.
