Perkinelmer JANUS & JANUS G3 Workstations May Display Horizontal Motion Error
Perkinelmer recalls JANUS and JANUS G3 Automated Workstations that may display a Horizontal Motion Error message, causing instrument downtime. Affected units have specific part numbers and were sold in clinical settings.
Lower-risk recall
We have become aware through internal testing that JANUS and Janus G3 Automated Workstations were failing production final acceptance testing due to a Horizontal Motion Error message displayed on the system. Further investigation concluded that two printed circuit boards (PCB) used in MDT models of Janus and Janus G3 were manufactured with the incorrect resistor values. This anomaly affects component part number 7101640 (PCB-Quad Motor Controller MDT) and part number 7101647 (PCB-Quad Motor Controller Gripper). This anomaly could result in the Horizontal Motion Error being displayed and result in instrument down time. Until PerkinElmer s corrective measures are completed, we request you; ¿ Be aware that there is potential for the Horizontal Motion Error message to display which could result in instrument down time. ¿ Follow guidance provided in the Janus Automated Workstation User Manual when the Horizontal Motion Error message displays. ¿ If you have additional questions, contact PerkinElmer Technical Support for further assistance (800) 762-4000.
