Steady Flow Selection (Dip Sw3 - Position 1) - Franklin Electric MONODRIVE UTILITY Manuel Du Propriétaire

INSTALLATION AND SETUP
Drive Configuration
Steady Flow Selection (DIP SW3 – Position 1)
The MonoDrive Utility is configured at the factory to ensure quick response to maintain constant
pressure. In some cases, when using a pressure sensor, the drive may offer better control through a
slower response time.
For example, if the system has a water line tapped before the pressure tank or close to the well
head, or where audible speed variations of the pump assembly can be heard through the pipes,
adjusting the pressure control response time by enabling the Steady Flow feature may be helpful.
After enabling this feature, the installer should check flow and pressure changes for possible
overshoot. A larger pressure tank and/or a wider margin between the regulated pressure and the
pressure relief valve pressure may be required because the Steady Flow feature reduces the drive's
reaction time to sudden changes in flow.
To activate the Steady Flow feature, remove power and allow voltage to discharge. Move DIP SW3
Position 1 to the SF (up) position. The new setting will not take effect until the drive is powered up.
Note: The Steady Flow feature will function with a pressure transducer; however, this practice is
not recommended. A more effective approach with a transducer is to adjust the System Response.
Refer to "System Response (DIP SW2 – Positions 2–4)" on page 24.
