HV FSD Card in SL01
In the event of an IOC communications error, the operations crew had no way of knowing if the BLMs were powered on.
To eliminate this deficiency, a BLM HV monitor was needed. We built and tested these FSD cards for our BLM HV mainframes.
These cards are now installed. The FSD screens have been updated to reflect these new inputs.
If HV is lost or turned off, we will now generate an FSD trip.
All of the BLM HV mainframes (mainframes SL01, W201, and BS04) are now part of the FSD system.
