AMETEK PART 21 REPORT ON TYCO/POTTER & BRUMFIELD RELAYS
The following information was received from AMETEK via facsimile:
"COMPONENT DESCRIPTION: Electro-mechanical 14 pin relays, with AC voltages of 120 and 240, and DC voltages of 12, 24, 48 and 110. The Tyco/[Potter & Brumfield] relays were removed from the Approved Supplier Listing in 2006. The relays can be installed in Ametek Solidstate Controls equipment, or provided as a spare part.
"PROBLEM YOU COULD SEE: Nuisance alarming or erratic operation of the equipment.
"CAUSE: The problem appears to be an age related degradation of unknown cause. A failure analysis performed by First Energy Laboratory Services identified a potential cause as a crinkled appearance on the surface of the moving contact pads resulting in uneven contact with the opposing stationary contact pad. Over time, a layer of oxidation forms on the pads inhibiting electrical contact and increasing resistance.
"EFFECT ON SYSTEM PERFORMANCE: Potential unstable output voltage caused by intermittent high relay resistance. The relays are generally used for alarm functions but can be used in control circuitry as well.
"ACTION REQUIRED: Replace all Tyco/Potter & Brumfield relays listed below remaining in service with the approved Ametek Solidstate Controls equivalent.
"Component: Tyco/Potter & Brumfield Relays
SCI PIN 07-740001 - P&B PIN KHAU-17A18-120
SCI PIN 07-740002 - P&B PIN KHAU-17A18-240
SCI PIN 07-740005 - P&B PIN KHAU-17D18-12
SCI PIN 07-740006 - P&B PIN KHAU-17D18-24
SCI PIN 07-740007 - P&B PIN KHAU-17D18-48
SCI PIN 07-740008 - P&B PIN KHAU-17D18-110"
The faulty relays are a subcomponent of AMETEK battery chargers, inverters, and uninterruptible power supplies. These types of AMETEK equipment are installed at various reactor licensees. There was no information on which licensees are affected. The manufacturer received notification of the faulty relays from Beaver Valley Power Station. The problem was revealed through a malfunction of a battery charger on 12/11/2008. The manufacturer does not believe that there is an immediate safety concern.
