The Perfect Pressure™ Easy Setup Wizard is a user-friendly tool integrated into our VFDs to simplify the configuration of constant water pressure systems. Upon initial startup, the wizard guides users through a series of prompts to establish the desired pressure settings. This streamlined process allows for quick and efficient setup, often requiring only a few minutes to complete.
Perfect Pressure™ Setup Process
Configure a pump system to deliver constant pressure with just a few button presses. After the setup wizard, validate the system and walk away knowing it will supply constant pressure no matter the demands placed on it.
Variable frequency drives have always been hard to configure. Needing to hunt through a complex manual trying to cross-reference parameters, while trying to configure them on barely readable screen was normal. Phase VFD’s still have all those parameters under the hood if you want to fine-tune a pump system, but our intuitive wizard will have you running in just a few seconds.
Try this interactive Perfect Pressure™ Wizard to see how easy it is!
Run Constant Pressure? STEP 1
On start, use the arrows to toggle to "Run Constant Pressure Wizard?" - Press the ENTER key to proceed.
4-20mA psi RANGE STEP 2
Set the psi range of the 4-20mA sensor. Default is 150psi. Press ENTER to proceed.
psi SETPOINT STEP 3
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.
SUBMERSIBLE PUMP STEP 4
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.
Disable Manual Mode STEP 5
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.
OVERCURRENT LIMIT STEP 6
Setting for motor overload protection (service factor amp rating for the motor) using the arrows to toggle. Press ENTER to proceed.
RUN/AUTO STEP 7
Press the RUN/AUTO button to start the pump.
