During preventative maintenance (pm), the autopulse platform (sn (b)(6)) powered up normally and passed the initial functional test, but the autopulse platform failed the load cell characterization check during further testing.The root cause of the noted issue was failed load cell #1, likely attributed to the age of the platform, failed component(s), or mishandling such as a drop.The autopulse platform was manufactured in october 2016 and is over 7 years old, beyond its expected service life of 5 years.Load cell #1 needs to be replaced to remedy the fault.Visual inspection of the returned autopulse platform showed no physical damage.During the visual brake gap inspection, it was observed that the drivetrain motor brake gap was too wide, out of specification.This issue is unrelated to the noted device failure and is most likely attributed to wear and tear.The brake gap needs to be adjusted to remedy the problem.Zoll is awaiting the customer's approval for repair.Historical complaints were reviewed for service information related to the reported complaint, and there was no previous history of complaints reported for the autopulse platform with serial number (b)(6).
