the median / average value from the OWS. The out puts of the transmitter shall be con tinuously monitored for

excessiv deviation, which shall be displayed, logged & alarmed. . Dual measurement scheme for analog inputs employing two independent transmitters,

connect ed to separate tapping points shall be employed for the remaining measur ements used in CLCS and TCS. he

output of the redundant transmi tters shall be continuously moni tored for excessive deviation. In case the deviation is within

limits , the mean value shall be used for the control loop. If the deviation beco mes high, the loop shall be automatically ransferred to manual.
