A getinge field service engineer (fse) evaluated the iabp unit and was able to reproduce the reported issue.In an attempt to fix the issue, the fse replaced the power supply board, motor control board, and ran the iabp for 2hrs; however, the issue was not solved.Also, the bulk supply fuse was blown again, so the fse replaced the fuse and removed the motor control board connections and switched on the iabp and observed electrical test code 50.The motor controller board was then replaced, the iabp was under observation for 15 days and there were no further issues reported.The iabp was then released to the customer and cleared for clinical service.
