DRIVE CONFIGURATION
Menu Settings
(motor speed) to maintain pressure at or near the target setpoint. For large operations that might require
several drives and pumps, refer to
NOTE: Factory defaults for the Setpoints are 0 PSI. This puts the drive in the Sleep/Stop state, keeping the
drive from turning on the pump while programming takes place. The Drive will run 5 seconds after SET-
POINT 1 is adjusted above 0 PSI and NEXT button is pressed.
Setpoint 1: When using a Pressure Transducer, use this screen to set the desired target pressure the system
will maintain during normal operation. Recommended maximum value is 5% less than sensor max for
proper operation. When programming, this setting scrolls by 1 PSI, then fast scrolls at an increased rate
when holding down the UP or DOWN button. This is true for Setpoint 2 as well.
IMPORTANT: Monitor pressure gauge during initial startup to ensure system does not over-pressurize.
Setpoint 2: When using a Pressure Transducer, an alternate setpoint can be set here and activated by clos-
ing a switch connected to the Dual Setpoint terminal block. If an application has different requirements for
pressure yet one well is being used, then the dual setpoint feature can be used to control the Setpoints
needed for the different application requirements.Refer to
Drawdown: When using a pressure transducer, the "cut-in" pressure offset can be set to allow for more
water to be drawn from the system pressure tank before a sleeping drive will wake up. This will reduce
sleep/wakeup cycles.
For example, a system setpoint pressure of 50 PSI and a drawdown value of 20 PSI would cause the drive to
maintain system pressure at 50 PSI when running; however when the system is idle, the drive will not start
the motor until the system pressure drops below 30 PSI.
System Response: System response time affects how the drive reacts to the pressure transducer/sensor
feedback. Faster response times can improve pressure stability in some systems. However, if the response is
too fast, the system could overshoot, leading to overpressure, rapid cycling, or hydraulic noise. Selections
include SLOW, MEDIUM, FAST, and Custom. These control the following configuration items:
•
Proportional Gain, default = 500
•
Integral Time, default = 25 (2.5 seconds)
•
Ramp Time, default = 10 (1.0 seconds)
•
Acceleration Time, default = 2s for SUB, 20s for CEN
•
Deceleration Time, default = 2s for SUB, 20s for CEN
Underload Sensitivity: The drive is configured to ensure detection of Underload faults in a wide variety of
pumping applications. In rare cases (as with certain pumps in shallow wells), this trip level may result in
unnecessary faults. If the pump is installed in a shallow well, activate the drive and observe system behavior.
Once the system begins to regulate pressure, check operation at several flow rates to make sure the default
sensitivity does not cause false Underload trips.
This setting scrolls by 1%, then fast scrolls with increased rate upon holding down UP or DOWN button.
Shallow Set: If the pump is installed in an extremely shallow well and the system continues to trip, then
•
adjust to a lower sensitivity setting. Check the Underload trip level and repeat as necessary.
Deep Set: In cases where the pump is set very deep, run the system at open discharge to pump the
•
well down and observe carefully that an Underload is detected properly. If the system does not trip as it
should, adjust to a higher sensitivity setting.
Underload Off Time: This setting determines how long the drive will wait before attempting to run after an
Underload event. The default is Smart Reset, but is user-adjustable from 5 minutes to 24 hours. This setting
scrolls by 1 MIN, then fast scrolls with increased rate upon holding down UP or DOWN button.
The default setting is SMART RESET. Smart reset will set the underload off time to 5 minutes for the first
fault. If the drive faults again immediately following the 5 minute off time, the next off time is doubled.
