    PRODUCT EVENT SUMMARY: TWO CONTROLLER AC ADAPTERS (B)(4) AND FIVE BATTERIES (B)(4) WERE RETURNED FOR EVALUATION. VARIOUS ANALYSES WERE CONDUCTED AND REVIEWED IN ORDER TO EVALUATE THE PERFORMANCE OF THE DEVICES IN RELATION TO THE REPORTED EVENT. FAILURE ANALYSIS OF THE RETURNED ADAPTERS AND BATTERIES REVEALED THAT THE DEVICES PASSED VISUAL INSPECTION AND FUNCTIONAL TESTING. LOG FILE ANALYSIS REVEALED THAT THE CONTROLLER IN USE DURING THE REPORTED EVENT, (B)(4), CONTAINED A FEATURE THAT RECORDS WHETHER A POWER SOURCE EXPERIENCED A COMMUNICATION ERROR OR A DISCONNECTION WITHIN EACH 15 MINUTE INTERVAL. ANALYSIS OF THE DATA LOG FILES REVEALED SEVERAL PREMATURE POWER SWITCHING EVENTS THAT WERE DUE TO MOMENTARY DISCONNECTIONS INVOLVING BATTERIES (B)(4). LOG FILE ANALYSIS ALSO REVEALED TWO CONTROLLER POWER-UP EVENTS, WITH ASSOCIATED MOTOR START EVENTS, ON (B)(6) 2018, INDICATING LOSSES OF POWER TO THE CONTROLLER LEADING TO PUMP STOPS. THE DATA POINT PRIOR TO THE FIRST LOSS OF POWER REVEALED THAT (B)(4) WAS CONNECTED TO POWER PORT ONE WITH 97% RELATIVE STATE OF CHARGE (RSOC) AND (B)(4) WAS CONNECTED TO POWER PORT TWO WITH 35% RSOC. THE DATA POINT RECORDED AFTER THE FIRST LOSS OF POWER REVEALED THAT (B)(4) WAS CONNECTED TO POWER PORT ONE AND (B)(4) WAS CONNECTED TO POWER PORT TWO. THE CONTROLLER WAS WITHOUT POWER FOR 12 SECONDS. THE DATA POINT PRIOR TO THE SECOND LOSS OF POWER REVEALED THAT AN ACTIVE POWER ADAPTER WAS CONNECTED TO POWER PORT ONE AND (B)(4) WAS CONNECTED TO POWER PORT TWO WITH 96% RSOC; THE CONTROLLER DOES NOT LOG THE SERIAL NUMBER OF ATTACHED ADAPTERS. THE DATA POINT RECORDED AFTER THE SECOND LOSS OF POWER REVEALED THAT (B)(4) WAS CONNECTED TO POWER PORT ONE AND (B)(4) WAS CONNECTED TO POWER PORT TWO. THE CONTROLLER WAS WITHOUT POWER FOR 12 SECONDS. SEVERAL MOMENTARY DISCONNECTIONS WERE RECORDED IN THE PERIODS LEADING UP TO THE LOSSES OF POWER. AS A RESULT, THE REPORTED POWER SWITCHING AND PUMP STOP EVENTS WERE CONFIRMED. LOG FILE ANALYSIS DID NOT REVEAL ANY CRITICAL BATTERY ALARMS LOGGED WITHIN THE ANALYZED PERIOD; THEREFORE, THE REPORTED CRITICAL BATTERY ALARM EVENT WAS NOT CONFIRMED. THERE IS NO EVIDENCE THAT THE LUBRICATION SERVICING WAS PERFORMED ON THE REPORTED DEVICES. THE MOST LIKELY ROOT CAUSE OF THE REPORTED POWER SWITCHING EVENT CAN BE ATTRIBUTED TO MOMENTARY DISCONNECTIONS BETWEEN THE CONTROLLER AND BATTERIES. A POSSIBLE ROOT CAUSE OF THE LOSSES OF POWER CAN BE ATTRIBUTED TO DISCONNECTIONS OF BOTH POWER SOURCES AND/OR TO INTERMITTENT DISCONNECTIONS ON ONE OR BOTH POWER SOURCES. AN INTERNAL INVESTIGATION INVESTIGATED MOMENTARY DISCONNECTIONS. AN INTERNAL INVESTIGATION WAS INITIATED TO CAPTURE EVENTS INVOLVING THE CONTROLLER LOSING POWER. ADDITIONAL PRODUCTS: (B)(4).
