Relay Protection and Safeguards System BF Relay BFD Relay BFD slave relays NBFD slave relays MG-6 Master Relay For the 7100 and 7300 Process Protection System printed circuit cards for RTS and ESFAS functions, the FMEA was performed, and testing was done to confirm the FMEA was accurate. In the case of the 7100 Process Protection System, the modules whicn were actually tested were the m V/l Amplifier, Summator, Function Generator, Comparator Module, Power Supply, and Multiplier / Divider. The Relay Module, isolator, and Signal l

Selector were not subjected to component replacement and test. For the 7300 Promss Protection System, the modules selected for test were the Multiplier / Divider, RTD Amplifier, Summing Amplifier, Function Generator, Loop Power Supply, and Comparator.

The modules not subjected to test were the Solid State Relay, Potentiometer, ChannLl Test i

module. Temperature Channel Test, Computer Input, Relay Card, and the Test Point.
