21.21 UNSPECIFIED PARAGRAPH ROSEMEOUNT 1154 PRESSURE TRANSMITTER CALIBRATION PROBLEM The supplier provided the following information via facsimile:
Pursuant to 10 CFR Part 21, section 21.21(b) Rosemount Nuclear Instruments, Inc. [RNII] is writing to inform NRC that a total of ten (10) Model 1154 and 1154 Series H output range code 4 pressure transmitters whose model code includes special option suffix N0026 or N0079 may not calibrate at all of the published values [9 shipped to 2 utility sites in the United States].
"During evaluation of two returned Model 1154 output range code 4 pressure transmitters with special option suffix N0026, the cause of the customer-reported calibration problem was isolated to the amplifier circuit card assembly (CCA). Upon replacement of the amplifier CCAs the two affected transmitters calibrated and functioned normally.
"During root cause analysis it was observed that a single resistor (R316) on each affected amplifier CCA had an incorrect resistance value. The R316 resistor enables a standard upper range limit (URL) of a transmitter with output range code four to be increased from 150 inches water to 210 inches water in combination with a minimum span of 75 inches water. This R316 resistor allows the transmitter to achieve performance specifications, calibration ranges, and spans as indicated by the special option drawing.
"To meet site specific application requirements transmitters may be field recalibrated to different upper and lower range values and/or spans. Model 1154 and 1154 Series H transmitters with special option suffix N0026 or N0079 and amplifier CCAs whose R316 resistors were not replaced during the sub-assembly process, will have incorrect resistance values and may not calibrate to all upper and lower range values and/or spans published for the applicable special option. However, if an affected transmitter has been successfully calibrated, having the incorrect resistance value will not adversely affect transmitter performance during normal operation or accident conditions.
08/14/2007 U.S. NuclearRegulatory Commission OperationsCenter Event Report Page 2 General Information or Other (PAR) Event# 43566 "The manufacturing records for the two returned Model 1154 transmitters (with amplifier CCAs with part number 01154-0001-0006) were carefully reviewed. The sub-assembly traveler lacked the required material traceability information, indicating that the R316 resistors were not replaced. In an abundance of caution RNII carefully reviewed all sub assembly travelers for part number 01154-0001-0006. No other discrepancies were found.
"The corrective action which has been taken; the name of the individual or organization responsible for that action; and the length of time taken to complete that action:
"(a) RNII verified all transmitters in production and finished goods with applicable special options utilizing 01154-0001-0006 amplifier CCA's contained the correct board and resistor. No discrepancies were found. (Complete:
7/24/2007)
"(b) RNII evaluated all 01154 CCA's in production to ensure they contained the correct resistor. No discrepancies were found. (Complete: 7/20/07)
"(c) RNII examined all manufacturing paperwork for 01154-0001-0006 amplifier CCAs built and shipped prior to 7/24/2007. No additional discrepancies were found. (Complete: 7/25/2007)
"(d) An internal corrective action request was initiated. All corrective actions will be completed by 8/15/07.
"The end user is advised to determine the impact of this potential non-conformance on its plant operations and safety and take action as deemed necessary. RNII can supply replacement 01154-0001-0006 amplifier CCAs which can be installed per section five of the product manual or the transmitter can be returned to RNII for rework.
If it is determined that return of affected transmitter(s) is required, RNII should be contacted to facilitate the return process."

.Attn: Document Control Desk Re: Notification under 10 CFR Part 21 for Certain Model 11514 and Model 1154 Series H Pressure Transmitters Pursuant to 10 CFR Part 21, section 21.21(b), Rosemount Nuclear Instruments, Inc.
(RNII) is writing to inform you that a total of ten (10) Model 1154 and 1154 Series H output range code 4 pressure transmitters whose model code includes special option suffix N0026 or N0079 as listed in the attached Appendix may not calibrate at all of the published values.
1.0 Name and address of the individual providing the information:
Mr. Marc Bumgarner Vice President & General Manager Rosemount Nuclear Instruments, Inc.
8200 Market Blvd Chanhassen, MN 55317 2.0 Identification of items supplied:
Ten (10) Model 1154 and 1154 Series H pressure transmitters (output range code 4) whose model code includes special option suffix N0026 or N0079 as identified in attached Appendix.
3.0 Identification of firm supplying the item:
Rosemount Nuclear Instruments, Inc.
8200 Market Blvd Chanhassen, MN 55317 4.0 Nature of the failure and potential safety hazard; During evaluation of two returned Model 1154 output range code 4 pressure transmitters with special option suffix N0026, the cause of the customer-reported calibration problem was isolated to the amplifier circuit card assembly (CCA). Upon replacement of the amplifier CCAs the two affected transmitters calibrated and functioned normally.
During root cause analysis it was observed that a single resistor (R31 5) on each affected amplifier CCA had an incorrect resistance value. The R316 resistor enables a standard upper range limit (URL) of a transmitter with output range code four to be increased from 150 inH 20 to 210 inH 20, in combination with a minimum span of 75 inH 2 0. This R316 resistor allows the transmitter to achieve performance specifications, calibration ranges, and spans as indicated by the special option drawing.

In the sub-assembly process, the R316 resistor on a standard amplifier CCA is replaced to create a new CCA part number (01154-0001-0006). The new resistor's material traceability information is recorded on the traveler. In final assembly, each transmitter with special option suffix N0026 and N0079 is assembled using one of these 01154-0001-0006 amplifier CCAs, It then receives a factory calibration check at 135 inH 20 to 210 inH 20, to ensure conformance to the minimum span and maximum URL specifications, as defined by the special option drawing. Appropriate manufacturing paperwork is used to document and record each amplifier CCA, as well as each final assembly transmitter.
To meet site specific application requirements, transmitters may be field recalibrated to different upper and lower range values and/or spans. Model 1154 and 1154 Series H transmitters with special option suffix N0026or N0079 and amplifier CCAs whose R316 resistors were not replaced during the sub-assembly process, will have incorrect resistance values and may not calibrate to all upper and lower range values andlor spans published for the applicable special option. However, if an affected transmitter has been successfully calibrated, having the incorrect resistance value will not adversely affect transmitter performance during normal operation or accident conditions.
The manufacturing records for the two returned Model 1154 transmitters (with amplifier CCAs with part number 01154-0001-0006) were carefully reviewed. The sub-assembly traveler lacked the required material traceability information, indicating that the R316 resistors were not replaced. In an abundance of caution, RNII carefully reviewed all sub-assembly travelers for part number 01154-0001-0006. No other discrepancies were found.
5.0 The corrective action which has been taken; the name of the individual or organization responsible for that action; and the length of time taken to complete that action:
(a) RNII verified all transmitters in production and finished goods with applicable special options utilizing 01154-0001-0006 amplifier CCA's contained the correct board and resistor. No discrepancies were found, (Complete: 7/24/2007)
(b) RNII evaluated all 01154-0001-0006 CCA's in production to ensure they contained the correct resistor. No discrepancies were found, (Complete:
7/20/2007)
(c) RNII examined all manufacturing paperwork for 01154-0001-0006 amplifier CCAs built and shipped prior to 7/2412007. No additional discrepancies were found. (Complete: 7/25/2007)
(d) An internal corrective action request was initiated. All corrective actions will be completed by 8/15/07, 6.0 Any advice related to the potential failure of the item:
The end user is advised to determine the impact of this potential non-conformance on its plant operations and safety and take action as deemed necessary. RNII can supply replacement 01154-0001-0006 amplifier CCAs which can be installed per section five of the product manual or the transmitter can be returned to RNII for rework. If it is determined that return of affected transmitter(s) is required, RNII should be contacted to facilitate the return process.
