INITIAL NOTIFICATION OF POTENTIAL DEFECT CLASS 1E TYPE CV-2 AND CV-22 RELAYS

"This letter is the initial notification of a deviation concerning our Class 1E type CV-2 and CV-22 relays.

"One of our customers notified us that several of the CV-2 relays they had recently received did not have a particular assembly on the moving disc which other CV-2 relays on the same order did have. Discussions with this customer concluded they were speaking of a weight assembly that is used in balancing the moving disc and is required as a part of the completed relay.

"Upon visual examination of the CV-2 relays returned to us for corrective action this deviation was confirmed. A preliminary investigation showed that our manufacturing system allowed for the potential for this deviation to occur.

"Details will be provided in our written notification forthcoming within the next thirty days."
