Note:
  • To change the command input signal from 2 VDC to 10 VDC to 4 mA to 20 mA, set the actuator DIP switch nr.3 to ON. Ensure actuator 1 is set to 4 mA to 20 mA.
  • DPT and DPS are optional features.
  • You need an RS485 to USB cable to connect the valve to the UVM Configuration Tool.
  • DIP switch 8 engages the RS485 terminating resistor. Activate one DIP switch per loop.
  • The user wires the power transformer and the UVM1000 module. The other input and output terminations are wired in the factory.

Figure 6. UVM connection process

You can configure actuated Venturi air valves with a factory mounted UVM1000 to meet a wide variety of application parameters. A USB to DB9 cable forms an RS485 connection between the air valve and the UVM configuration tool software. You can download the UVM configuration software from the Licensing Portal. For more information, contact your sales representative.
