Detection 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.

See Note
Acceleration Time 1
Time it takes to accelerate the pump motor from zero to maximum speed.
NOTE: Factory default with Thrust Mode enabled is 12.0 sec, 20.0 sec when disabled.
Adjusted depending on system
performance
C1-02
10.0 sec.
See Note
Deceleration Time 1
Time it takes to decelerate the pump motor from maximum speed to zero.
NOTE: Factory default with Thrust Mode enabled is 5.0 sec, 10.0 sec when disabled.
L5-01 5 Number of Restart Attempts
Determines the number of times iQpump will perform an automatic restart on the faults listed
in the comments column.
iQpump System Protection Faults that can be setup to restart are Low Level Feedback,
High Level Feedback, Transducer Loss, Not Maintaining Setpoint, Loss of Prime,
Pump Over Cycle. Refer to parameters P4-07 and P4-08. The number of restart attempts is
set by L5-01.

x Ground Fault
x Output Phase Loss
x Input Phase Loss
x iQpump Overload
x Motor Overload

L5-03 20 sec. Maximum Restart Time After Fault
If the restart fails (or is not attempted due to a continuing fault condition) iQpump waits the
Maximum Restart Time After Fault, before attempting another restart.
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)
P1-06 should be set to the level
where the pump can produce the
minimum pressure even at zero
flow.
P2-03 5 sec. Sleep Delay Time
Time it takes before the pump system goes to sleep when the selected signal level (P2-01)
falls below the specified sleep level (P2-02)
Adjust according to system
requirements.
P4-12 30.0 Hz Thrust Bearing Frequency Sets the frequency reference used when the thrust bearing function is active. A value of 0
disables this function.
Primarily used for submersible
pumps. Program P4-12 = 0.0 Hz
to disable function when iQpump is
used with a centrifugal pump.
P4-17 0.2 Min Utility Start Delay
When utility power is restored and P4-10 is enabled (1), iQpump waits the time specified in
P4-11 before auto operation becomes active.
Note: Only active when P4-10 is
enabled (1) and operation
(start/stop) is from the
digital operator.
THRUST BEARING - SUBMERSIBLE MOTORS
When u using a submersible motor in combination
with the iQpump, it is recommended to use the
Thrust Bearing function to prevent excess motor
wear. To enable this function, enter the minimum
motor frequency in parameter
P4-11. Example: Minimum motor speed 1800
RPM, 1800 RPM ÷ 3600 RPM x 60.0 Hz = 3

LOW/HIGH FEEDBACK LEVEL DETECTION
AUTO OPERATION – POWER DOWN STORAGE 8
Allows iQpump to automatically start after power failure when operated from keypad / digital operator. This function is
recommended for use when operating the iQpump in remote / unmanned areas. Use parameter P4-10 to enable.
When the iQpump is powered down while running, an internal run
command will automatically be initiated upon power-up.
This function is used when the pump system requires to be pre-charged before normal operation. Upon start the
iQpump will run at a fixed speed for a specified time or until the feedback signal reaches a programmed level after
which it will switch to auto mode operation.

SETPOINT
SET-POINT NOT MET
P1-16 Setpoint-LOP Tim
The iQpump can display a ‘S Setpoint Not Met’ fault when the iQpump is unable to maintain the programmed system
setpoint due a problem with the pump system. Set P1-15 to the maximum allowed difference between setpoint and
feedback level.
P1-11
P1-15 Max Setpoint Diff
iQpump continuously monitors the system feedback signal. To display a ‘L Low Feedback’ fault set the low feedback
level parameter P1-08 to the minimum feedback level allowed for your system and to display a ‘H High Feedback’ fault
set the high feedback level parameter P1-11 to the maximum feedback level allowed.
