Application Preset Displays selected applications, see Step 5.
Comment:
Read-only cannot be modified. Factory set to (0: Pressure control)
E2-01
Drive Size
Dependent
Motor Rated Current Set to the motor nameplate full load amps.
Comment:
For submersible motors use service factor amps (SFA).
E2-04 2
Number of Motor
Poles
Sets the number of motor poles.
Number of motor poles is used to show the correct motor RPM on the display
Enter ’4’ for an 1800 RPM motor and ‘2’ for a 3600 RPM motor.
Comment:
Confirm number of poles: 2 Pole Motor = 3600 RPM, 4 Pole Motor = 1800 RPM, 6 Pole Motor = 1200 RPM, 8 Pole Motor = 900 RPM
P1-03 145.0
Feedback Device
Scaling
Sets the scaling of feedback device in user-set units.
System Scaling: Enter feedback device maximum:
Example: Enter 200 for pressure transducer with a maximum of 200 PSI at 20mA.
Comment:
Confirm feedback device scaling. (See Illustration 1)
Q1-01 0.0
PID Controller Set-
point 1
Sets the PID Setpoint when b1-01 is set to 0.
Comment:
Set to system pressure
Parameter Value Description Reference
P1-04 0.0 PSI
Start / Drawn Down
Level
The system starts when the feedback level drops below the start level for the time set in P1-05
(default 1 sec). This level also specifies the wakeup level when the drive is in Sleep Mode. When
this parameter is set to a negative value, the feedback level must drop that amount below the
setpoint. Setting this parameter to 0.0 disables the function. When P1-01, Pump Mode, is set to
3 (MEMOBUS network), this function is active only on the first drive in the network.
Programming the Start Level as an Absolute
Value. Start / Draw Down Level must be programmed to a positive value for the Start / Draw
Down Level to be an absolute value.
Example: Start / Draw Down Level P1-04 set to 50 PSI and delay time P1-05 set to 5 sec.
Result: Pump system will start when the pressure drops below 50 PSI for 5 sec.
Programming the Start Level as a Delta Level from the System Setpoint
Start / Draw Down Level must be programmed to a negative value for the Start Level to be a
delta value from the setpoint.
Example: Start / Draw Down Level P1-04 set to –10 PSI with a system setpoint of 50 PSI and de-
lay time P1-05 set to 5 sec.
Result: Pump system will start when the pressure drops below 40 PSI (50 - 10) for 5 sec.
Comment:
It is mandatory to program the Start / Draw Down Level in order to use the sleep function. (See Illustration 2 and 3 below)
P1-06 40.0 Hz
Minimum Pump
Speed
Minimum speed (Hz) for pump motor operation.
Example: Base pump motor speed is 3600 RPM, minimum speed is 2400 RPM.
Set minimum pump frequency to 40.0 Hz. (2400 ÷ 3600 x 60 Hz = 40 Hz)
Comment:
Minimum pump frequency should be set to the value at which the pump enters a no-flow condition.
P4-10 0
Disabled
AUTO Mode Opera-
tor Run Power Down
Storage
Stores the run status in the AUTO mode when operating from digital operator (b1-02=0).
0: Disabled
1: Enabled
WARNING! Sudden Movement Hazard. If the drive is powered down while running, it will
automatically initiate an internal Run command upon power-up.
Comment:
Recommended for use when the Start/Stop command is from the digital operator (See Step 9)

Comment:
HAND key on digital operator. (See Step 10)
