Por-. 1 Problem I
Amerace Corporation has identified a premature time-out condition with Agastat Model 7012D Pneumatic Timing Relays date coded 7740 through 7840. Bechtel's Supplier Quality Information Bulletin (SQIB) 80-5, Revision 1, includes all Model 7000 Series Timers in their surveillance inspection effort. PVNGS jobsite quality assurance conducted a surveillance of Units 1 and 2 Diesel Generator Control l
Panels 1-J-DGA<B01, 1-J-DGB-B01, 2-J-DGA-B01 and 2-J-DGB-B01.
A total of nineteen (19) timing relays with the suspect date codes were recorded. These include Models 7012 and 7022.
Additional surveillance activity so far has indicated this problem is limited to the equipment supplied by Cooper Energy Services as part of the Diesel Generator Purchase Order 13-MH-l 018.
