Drive Size
Dependent
Motor Rated Current Set to the motor nameplate full load amps.
For submersible motors use service
factor amps (SFA).
E2-04 2 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.
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
Feedback Device
Scaling System Scaling: Enter feedback device maximum:
Example: Enter 200 for pressure transducer with a maximum of 200 PSI at 20mA.
Confirm feedback device scaling.
(See Illustration 1)
d1-01 0 Set-Point 1 Set System Set-Point Set to system pressure
P1-04 0.0 PSI Start Level
When the iQpump is turned On and the feedback signal level (transducer) falls below this
level, the pump system will start after the time specified in P1-05 (default 1 sec).
Programming the Start Level as an Absolute Value
Start Level has to programmed to a positive value in order for the Start Level to be an
absolute value. Example: Start Level P1-04 set to 50 PSI and delay time P1-05 set to
5 sec. 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 Set-Point
Start Level has to programmed to a negative value in order for the Start Level to be a
delta value from the set-point.
Example: Start Level P1-04 set to –10 PSI with a system set-point of 50 PSI and a delay
time P1-05 set to 5 sec. Pump system will start when the pressure drops below 40 PSI
(50 - 10) for 5 sec.
It is mandatory to program the Start Level
in order to use the sleep function.
(See Illustration 2 and 3)
P1-06 40.0 Hz
Minimum Pump
Frequency
Minimum speed (Hz) the pump motor has to operate at.
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)
Minimum pump frequency should be set to
a value where the pump enters a no-flow
condition.
