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

Feedback Device Scaling
System Scaling: Enter feedback device maximum.
Example: Enter 200 for pressure transducer with a maximum of 200 psi
at 20 mA.
Confirm feedback device scaling.

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
Setpoint
Start Level has to programmed to a negative value in order for the Start
Level to be a delta value from the setpoint.
Example: Start Level P1-04 set to –10 PSI with a system setpoint 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.

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 the 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
the no-flow condition.

Selection
Select what to do when the feedback device (transducer) fails or gets
disconnected.
0: Disabled, continue running no message is displayed.
1: Alarm, show warning on the keypad when the feedback device fails
or is disconnected.
2: Fault, stop pump system when the feedback fails or is disconnected.
Note: Disable parameter b5-12 if no
transducer is installed.
Use to change the sign.
