Safety upgrade to pallet system. The upgrade provided CAT3 protection to the process and integrated with the existing plc / hmi to provide simple failsafe operation.
Safety plc – A safety system was already implemented but did not provide adequate fail-safe protection, it was possible to enter the area without the safety system operating. The system was upgraded to provide CAT3 protection via the existing light curtains. A new programmable safety plc was integrated and changes were made to the drive supplies, plc software and hmi.
