  1. On start, use the arrows to toggle to "Run Constant Pressure Wizard?" - Press the ENTER key to proceed.
  2. "Max Analog Sensor Range" - Set the psi range of the 4-20mA sensor. Default is 150psi. Press ENTER to proceed.
  3. "Analog Setpoint" - Determines the pressure you want to maintain. The factory default is 50 psi. Use the arrow keys to change if desired. Press ENTER to proceed.
  4. "Submersible Pump" - This parameter sets the ramp profile for a submersible pump. "YES" = ramps to 30HZ in the first second to prevent excessive wear on the thrust bearing. "NO" = The frequency will increase in a linear fashion from zero to max frequency. Use the arrow keys to toggle between the two settings. Press ENTER to proceed.
  5. "Disable Manual Mode" – The "Yes" value allows you to disable the MANUAL button run mode. "No" allows you to run the VFD manually on/off at max frequency.
  6. "Overcurrent Limit" – Setting for motor overload protection (service factor amp rating for the motor) using the arrows to toggle. Press ENTER to proceed.
  7. Press the RUN/AUTO button to start the pump.
Additional Notes:
  1. Motor rotation must be verified upon completion of setup.
  2. If the VFD is not going to sleep, first check for leaks. If there are no leaks present in the system, you may need to increase the "Shutoff Frequency" within "Constant Pressure Parameters."
  3. Set pressure tank psi to 70% of VFD psi Setpoint.
  4. Any of these settings can be modified if needed after the initial setup completes. For a full listing of available parameters, please refer to the product manual.
