PUMP SYSTEM FAULT SETUP
The iQpump Micro can display a 'Setpoint Not Met' fault when the iQpump Micro 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.
SETPOINT
10.5
LOW/HIGH FEEDBACK LEVEL DETECTION
The iQpump Micro continuously monitors the system feedback signal. Set the low feedback level parameter P1-08
to the minimum feedback level allowed for your system to display a 'Low Feedback' fault. Set the high feedback
level parameter P1-11 to the maximum feedback level allowed to display a 'High Feedback' fault.
10.6
PRE-CHARGE OPERATION
This function is used when the pump system requires a pre-charge before normal operation. Upon start the iQpump
Micro 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.

THRUST BEARING - SUBMERSIBLE MOTORS
The factory recommends using the Thrust Bearing
function to prevent excess motor wear when using
a submersible motor in combination with the
iQpump Micro. Enter the minimum motor
frequency in parameter P4-11 to enable this
function. Example: Minimum motor speed 1800
RPM, 1800 RPM ÷ 3600 RPM x 60.0 Hz = 30.0 Hz
Thrust Acceleration Time P4-11
(Example 1.0 sec.)
Thrust Bearing Frequency P4-12
(Example 30.0 Hz)
10.8
AUTO OPERATION - POWER DOWN STORAGE
Allows the iQpump Micro to automatically start after power failure when operated from the digital operator. This
function is recommended when operating the iQpump Micro in remote/unmanned areas.
Use parameter P4-10 to enable this function.
WARNING! Stay Clear- Equipment starts automatically. An internal run command will
automatically occur on power-up if the iQpump Micro is powered down while running.
