Emerson Process Management Rosemount Nuclear Instruments, Inc.
820D Market Blvd Chanhassen, MN 55317 4.0 Nature of the failure and potential safety hazard:
For every RNII Model 1153 and Model 1154 transmitter, four diodes are used on a circuit card assembly which is installed and sealed within the sensor module sub-assembly.
The primary function of these diodes is to convert an AC oscillator signal to a DC current that is proportional to the capacitance of the sensor. The diodes (P/N D2911218A) are manufactured by Microsemi Corp. (MSC).
Recently during standard receiving inspection, it was noted that the glass packaging on several of the diodes exhibited an unusual "cloudy' appearance. Upon supplier analysis it was determined that the cloudy appearance was due to interaction between cleaning solution and metallic components of the diode. Cleaning solution was able to penetrate the glass diode package because of a poor hermetic seal. Over time, this condition could degrade the performance and reliability of the diode, particularly at elevated temperatures. The resultant effect on the transmitter might include degraded temperature effect performance and increased drift between calibration cycles, Through further internal investigation MSC was able to bound the potential problem to two lot codes. These lot codes were traced from MSC through our circuit card supplier anci to RNII to identify the shipped transmitters affected by this notification.
RNII built up several test transmitters using diodes having a cloudy appearance and performed thermal aging on the transmitters to simulate typical operating conditions, followed by high temperature testing. Test results suggest that potentially affected transmitters would operate within published performance specifications, including the Nuclear Steam Pressure/Temperature specification. Nonetheless, RNII and MSC were unable to demonstrate the long term reliability of the suspect diodes over the full qualified life of the transmitter.
Therefore, based on analysis of the test results, RNII has established the following qualified life limits for transmitters affected by this .notification. This specification supersedes the published qualified life for all pressure transmitters affected by this notification:
Interim Quallfied Life = 5.1 years @ 120 0 F Operating Temperature RNII does not have sufficient information relative to each end user's specific applications to determine the potential safety-related impact of this notification to each end user's plant. Each end user must determine the impact on its plant operations and plant safety and take action as deemed necessary.

tooln 1c~cs ON :M/1,] CC:T SQL 9OZ/Z/CO 5.0 The corrective action which is taken, the name of the individual or organization responsible for that action, and the length of time taken to complete that action; (a) RNII held shipments of completed Model 1153 and Model 1154 transmitters while a determination was made as to which units were assembled with diodes from the suspect lot codes.
(b) RNII quarantined all Model 1153 and Model 1154 transmitters and module sub-assemblies in manufacturing while a determination was made as to which units were being assembled wIth diodes from the suspect lot codes.
(c) RNII issued a corrective action request to the diode supplier (MSC). MSC determined root cause, identified the suspect diode lots, and implemented corrective action. RNII verified the suppliers corrective actions during an on-site visit.
(d) RNII has reworked all pressure transmitters that were completed or in production that contained diodes from the suspect lot.
(e) RNII completed analysis and testing of pressure transmitters built with affected diodes to assess the impact of the non-conforming hermetic seal on performance and reliability of the pressure transmitter.
(f) RNII established an interim qualified life for pressure transmitters affected by this notification as noted in Section 4.0.
(g) Since no visual inspection of the diode is possible on shipped transmitters, RNII will rework any potentially affected pressure transmitter by replacing the module sub-assembly at the end user's request. Completion: As required.
6.0 Any advice related to the potential failure of the item:
The end user must determine the impact of this potential non-conformance upon its plant's operation and safety, and take action as deemed necessary. RNII recommends that potentially affected transmitters be returned to RNII for replacement of the module at the end user's earliest opportunity and consistent with the abbreviated interim qualified life specification noted in section 4.0. Please contact RNII to facilitate the transmitter return process as necessary.
