• ML20028C266 - LER 82-097/03L-0:on 821204,fire detection sys alarm for 4 kV switchgear room received due to pyralarm detector alarming for no apparent reason.Caused by low setpoint.New detector installed. (1 page(s), 12/4/1982)
• ML20028C270 - LER 82-098/03L-0:on 821127,fire detection sys alarm for 4 kV switchgear room received due to pyralarm detector alarming. Caused by low alarm setpoint.Pyralarm replaced. (1 page(s), 12/22/1982)
• ML20028C278 - LER 82-099/03L-0:on 821123,during surveillance test on automatic load sequence timing relays,four ESF timers found to exceed allowed tolerance.Caused by instrument drift. Timers readjusted & solid state relays under review. (1 page(s), 12/22/1982)
• ML20028C282 - LER 82-100/03L-0:on 821130,during surveillance test on diesel generator load shedding relays,six 4 kV loss of voltage relays exceeded allowed tolerance.Caused by instrument drift.Undervoltage relay under study. (1 page(s), 12/22/1982)
• ML20028C286 - LER 82-101/03L-0:on 821124,discovered time delay of two automatic load sequence relay timers not repeatable & timers exceeded allowed tolerance.Caused by toggle switch assemblies being out of alignment.Assemblies replaced. (1 page(s), 12/22/1982)
