    • CHAINS can be manually or automatically run in 6 different modes:
      • Run the CHAIN one time and stop
      • Run the CHAINS sequentially
      • Run the CHAIN one time. If a proximity switch is closed at the end, stop.
      • Run as above – At the end, go to the next CHAIN
      • Run a CHAIN 2-99 times and stop
      • Run a CHAIN 2-99 times and go to the next CHAIN
