| Title | Part 21 Report - Flow Scanner 6.6 Code Error |
| Event Description | The following information was received via e-mail:
Fisher Information Notice: FIN 2017-04: Erroneous Rotary Seating Torque Calculation in FlowScanner Software This Fisher Information Notice (FIN) applies only to the equipment identified in Appendix A, which lists serial numbers and order numbers that were delivered to customers. Specifically, it applies to FlowScanner 6.6 (build 6.6.000.29) and 6.6 SP1 (build 6.6.000.67). Appendix B of this document includes a decision tree to help customers further determine if this FIN applies to any work performed. The purpose of this FIN is to alert affected customers that, as of 29 June 2017, Fisher Controls International LLC (Fisher) became aware of a situation which may affect the performance of the aforementioned equipment. Fisher is informing affected customers of this circumstance in accordance with Section 21.21 (b) of 10 CFR 21. In the process of updating a customer's older FlowScanner software version to 6.6.000.67 (SP1), the customer performed additional software acceptance validation and discovered a discrepancy between the two software versions when calculating Seating Torque values for Rotary Valve assemblies with Lever Arm linkage type. An equation in 6.6.000.67 is the cause for the discrepancy. This equation was incorrectly written in code with a lack of an additional set of parentheses to order the execution of mathematical functions correctly. In code writing, this is considered a typographical error. When FlowScanner 6.6 was in development, there was a need to incorporate a new actuator design into the FlowScanner torque calculations. Because of the design of this actuator, the torque equations and configuration database in FlowScanner required modification. This code was modified on 7 November 2012. FlowScanner 6.6 (build 6.6.000.29) and 6.6 SP1 (build 6.6.000.67) were released subsequent this date and contained the erroneous calculation. Shipments of software were stopped on 30 July 2017 and no shipments took place between 29 June 2017 and 30 July 2017. This code was not transferred to the QUIKLOOK FS software utilized on the QUIKLOOK 3-FS diagnostic system. Thus, this error does not extend into QUIKLOOK FS software. The equation has been corrected and full-installation CDs will be ready for distribution to affected customers by 1 December 2017. In addition, a Corrective Action Request (CAR 2017-009) has been initiated by Fisher to prevent reoccurrence of this issue. Additionally, Software Error Notice SEN17-01 was created and released to affected customers on 2 August 2017. Fisher requests that the recipient of this FlN review it and take appropriate action in accordance with 10 CFR 21.

If 'YES', do you use FlowScanner 6.6 or 6.6 SP1 to complete a 'Dynamic Scan' test on rotary valves with lever arm linkages? Such as any TAG configured with 'LEVER ARM' in the 'Linkage Type' field for example Fisher Types 1052, 2052, and 1061 If 'YES', do you manually select the significant points for Seating Torque and Break Out Torque from the 'Dynamic Scan' test? If 'YES', do you use the Seating Torque result value provided by FlowScanner for any qualification, validation, or acceptance activities? If you answered 'NO' to ALL of these questions, this software error does not affect your usage of the FlowScanner 6.6 or 6.6 SP1 software. If you answered 'YES' to ANY of the questions, further evaluation of the affected Seating Torque test results may be necessary. A workaround has been issued to affected customers. |
