Updated: evaluation codes.The reported complaint was confirmed.Per data log analysis, this roller pump was not configured to the perfusion screen and was used as a stand alone pump.The pump logs show the pump was stopped but from local control, no problems are observed.The service repair technician (srt) could not duplicate the reported issue.As a precautionary measure the srt replaced the membrane display.No additional action will be taken at this time.
