  1. Press the KO\/KC button to drive the valve to the fully closed position.<\/li>
  2. Hold the KS button and then the KC button until L2 is turned on about 3-4 seconds later which means the fully closed position configuration is done.<\/li>

        Turn SA to 1 to start modulation.<\/p>

        • After power-on, the actuator defaults to follow the 4-20mA input signal for modulation.<\/li>
        • Sending commands through modbus enables the actuator to work in communication control mode and automatically return to analog control mode after the actuator is powered off and on again.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

          • The actuator will drive the valve to the specific position as the 4-20mA input signal stands for.<\/li>
          • The 4-20mA output signal will output the valve position in real time.<\/li>
          • The \u201cON\/OFF Output Open\u201d will output an effective signal(connect to COM) when the valve was driven to the fully open position.<\/li>
          • The \u201cON\/OFF Output Shut\u201d will output an effective signal(connect to COM) when the valve was driven to the fully close position.<\/li>
          • The actuator will drive the valve to the Safety position when supply power was broken down or input signal is fault.<\/li>
          • The actuator will return to modulation mode after supply power and input signal is recovered.<\/li><\/ul>

            \u00a0<\/p>

            Note: You can turn SW2 to 3 to activate the reverse operation. In which, 4mA input value will be transferred as 20mA, and 20mA will be transferred as 4mA. So the modulation is just like reversed.<\/em><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
