Additional Manufacturer Narrative

THE OLYMPUS FIELD SERVICE ENGINEER (FSE) WAS ONSITE AT THE TIME OF THE EVENT AND WAS NOTIFIED OF THE EVENT. THE FSE NOTICED SMELL OF SMOKE COMING FROM THE UPS DEVICE BUT SAW NO PHYSICAL SIGNS OF DAMAGE. THE FSE NOTED THAT THE ONLY DEVICE ATTACHED TO THIS UPS WAS THE ENDOWORKS COMPUTER. ALL OTHER DEVICES (MONITOR, VIDEO PROCESSOR., LIGHT SOURCE, ETC) WERE ALL POWERED BY THE TRANSFORMER ON THE ENDOSCOPY CART. THE FSE RE-APPLIED POWER TO THE ENDOSCOPY CART, TURNED ON ALL EQUIPMENT ON THE ENDOSCOPY CART, AND OBSERVED NO MALFUNCTIONS OF ANY DEVICE NOR ANY SMOKE COMING FROM THE UPS DEVICE. THE FSE WAS ASKED TO REMOVE THE UPS FROM THE ENDOSCOPY CART. THE UPS WAS RETURNED FOR EVALUATION. IT WAS CONFIRMED THAT THE UPS WAS MALFUNCTIONING. THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE UPS WAS REPLACED.

Description of Event or Problem

THEREAFTER, SMOKE WAS OBSERVED COMING FROM THE UNINTERRUPTIBLE POWER SUPPLY (UPS) USED IN THE ENDOSCOPY CART.

THE SECONDARY CART WAS USED WITHOUT ANY FURTHER ISSUES. THIS CASE STUDY WAS COMPLETED.
