NRR111621260(Letter Item 9) - This item will be corrected by a design change based on the following:The Unit 1/Unit 2 Eagle 21 configuration has a sufficient number of spare Narrow Range (NR) and Wide Range (WR) RTD inputs available on the installed ERI-01 and ERI-02 boards to wire these spare inputs to the active channels. The spare input will provide the parallel resistance to resolve the problem. The WR RTD inputs provide the same input impedance as the NR RTD inputs. Jumpers will be installed at the Eagle 21 termination frame to provide a parallel connection from each existing NR RTD input to an existing spare input, thus simulating the hardware connection for shared RTDs. Therefore, as configured, the Rack 2 Loop Calculation Processor (LCP) will provide the correct temperature calculation for the NR RTDs.
