conditions. Speci6cally, contacts 12 and 13. designated ' spare' on the drawing are energized with 10 VAC. The wiring diagram esidently had r.ot been updated as part of a modi 6 cation done under Project Assignment 84-63 which had used the contacts.
An additional concern exists in the fact that presentise maintenance actisities base l
been routinely performed in the past with no one reporting soltage at contacts 12 and 13.
r i
Request Please discuss the valicity of the abose assertions. If any de6ciencies are identi6ed m wiring diagrams and or drawings, or in the procedural cor. trol of presentise maintenance activities, please proside us with the corrective actions you hase taken to prevent recurrence. Please provide us with an assessment of the significance with regard to safety of any identi6ed de6ciencies.
