Automatic transfer switch ATS021 ATS021: Analyzing the voltage, frequency, and phase balance. Includes the generator START / STOP command. ATS021 has two sensors to monitor two three-phase power lines, both able to also work with single phase. Figure 2.4 ATS021 have the capability to monitor two three-phase power lines, both able to also work with single phase. - Page 9 Installation and operating instructions, ATS021 2. Product overview With DIP switches, it can be chosen whether or not the N-line is connected. If ATS021 is used without the N-line, the external transformer must be used. Figure 2.5 If ATS021 is used without the N-line, the external transformer must be used.
