When a failed contactor brought attention to an aging control system, a plastics manufacturer used the opportunity to modernize its 50HP granulator. A phased retrofit replaced hardwired relays and a wye-delta starter with a Productivity1000 PLC, C-more HMI, and Stellar soft starter. Adding current monitoring now allows the PLC to stop the infeed before jams occur, helping eliminate cleanouts that once caused up to 45 minutes of downtime.
