Subject:
Interim Notification Report for PotentialPurt2l
Dear Sir or Madam:
This letter is being provided as an interim notification on a failure of a Curtiss Wright (CW) supplied Tyco (Agastat) safety related relay. The relay is identified as Agastat Part Number E7I02PELL004, Mfg serial number 16120301, CW tag # CJ583101, CW SAI02.
Duke Energy (Catawba Plant) notified CW on June 22, 2023 of the failure via letter. The Duke letter and background information is provided with this notification. Per Duke non-conformance details N.C. contacts 4 and 6 were found sticking in the open position. The contacts were cycled several times by Duke and eventually broke free. The relay was returned to CW for evaluation, however CW could not duplicate the failure.
As the relay is questionable for reliable service at this point CW is having the relay returned to Tyco for their evaluation. Once the evaluation is complete this report will be updated. CW anticipates an update to this notification with final results by October 15ft.
Sincerely:
