During servicing at zoll, the autopulse platform (b)(6) failed initial functional testing due to fault 27 (encoder fault).The root cause for the observed fault was due to a failure of the integrated encoder gearbox, likely attributed to the age of the device.The autopulse platform was manufactured in 2008 and is 16 years old, past its expected service life of 5 years.Upon visual inspection, a cracked /damaged top cover and a hole that affects the watertight seal of the load plate cover were observed.The probable root cause for the observed physical damages was due to mishandling.Also, the brake gap was too wide (out of specification), likely attributed to wear and tear due to the age of the device.The initial functional testing of the ap platform could not be performed due to the displayed fault 27 (encoder fault).The encoder will need to be replaced to remedy the fault code.However, the repair was rejected by the customer and the device will be disposed of by zoll germany.Historical complaints were reviewed for service information related to the reported complaint, and there was no previous history of complaints for autopulse platform with (b)(6).
