PUMP SYSTEM FAULT SETUP
The iQpump can display a '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.

LOW/HIGH FEEDBACK LEVEL DETECTION
iQpump continuously monitors the system feedback signal. To display a ' Low Feedback' fault set the low feedback
level parameter P1-08 to the minimum feedback level allowed for your system and to display a 'High Feedback'
fault set the high feedback level parameter P1-11 to the maximum feedback level allowed.
6
PRE-CHARGE OPERATION
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.

P4-01 Pre-Charge Level: Specified feedback level to stop pre-charge operation
P4-02 Pre-Charge Frequency: Set desired pre-charge speed
P4-03 Pre-Charge Time: Specified maximum pre-charge operation time

THRUST BEARING - SUBMERSIBLE MOTORS
When 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 = 30.0 Hz
Thrust Acceleration Time P4-11
(Example 1.0 sec.)
Thrust Bearing Frequency P4-12
(Example 30.0 Hz)

AUTO OPERATION – POWER DOWN STORAGE
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.
