ATS Automatic Transfer Switch System

                             ATS control module

                             Automatic Transfer Switch Control Module. The module features 8-Bit microprocessor
                             control. The module is used to monitor two 3-phase AC supply. Once I# AC supply
                             failure is detected (under voltage,over voltage,miss phase), The module Automatically
                             transfer the switch to II# AC supply,  and control generator to start.

           IC-NT Synchronizing controller

          ● Essential load is fed by two mains feeders during normal
            operation  to  achieve  maximum  reliability  of  the  power
            delivery. Bus-tie breaker (BTB) is closed.
          ● Complex switching algorithm running in external PLC defines
            which  breakers  are  opened  and  which  are  closed
            independent on availability of two mains and gen-sets.
          ●  Reverse  synchronizing  on  both  feeders  and  on  bus-tie
            breaker  is  accomplished  by  5  InteliMainsNT  modules
            controlled by external PLC.
          ● Active and reactive load-sharing can operate in two modes:
                  ⚶ Sharing the load between all running gen-sets      ⚶ if BTB is closed
                  ⚶ Sharing the load in two independent groups           ⚶ if BTB is opened
          ● Automatic power dependant start/stop can operate in two modes as well:
                  ⚶ Running on all gen-sets    ⚶ if BTB is closed
                  ⚶ Running in two independent groups   ⚶ if BTB is opened
          ● All controllers are interconnected by one CAN bus all the time, disregarded if BTB is closed or open, no
            need for relays reconnecting the CAN bus.
          ● Complete system is remotely controlled and supervised from Control room connected via company LAN
            and IG-IB to all controllers.
