The BUS-3 signaling and control unit is required to integrate the KZEG valve into a third-party gas contamination control system that does not use the RS-485 interface. Bus-3 finds an alternative application in the "Kristall" gas contamination control system, in the case of simultaneous use of two valves with simultaneous shutdown in the event of an accident.
