IntelliFlo Installation and User’s Guide

Alerts and Warnings

The IntelliFlo displays all alarms and warnings on the control panel display. When an alarm or warning
condition exists, the corresponding LED will be lit on the display. All control panel buttons are disabled until
the alarm or warning is acknowledged with the Enter button. Press the Reset button to
clear the alarm once the fault condition has been resolved. Note: The IntelliFlo pump will
not start if the impeller is rotating. The alerts and warnings are:

Power out failure:

The incoming supply voltage is less than 170 VAC. The drive

faults to protect itself from over current. The drive contains capacitors that keep
it powered up long enough to save the current run parameters. If power is
restored during this process, approximately 20 seconds, the drive will not restart
until completed.

Priming error:

The incoming supply voltage is less than 170 VAC. The drive

faults to protect itself from over current. The drive contains capacitors that keep
it powered up long enough to save the current run parameters. If power is
restored during this process, approximately 20 seconds, the drive will not restart
until completed.

Overheat alert:

If the drive temperature gets above 130 degrees, the IntelliFlo

will slowly reduce speed until the over temperature condition clears.

Anti-freezing:

When active, the motor will run at 1000 rpm for 60 minutes. Only active in Filter and

Manual modes. Note: The IntelliFlo's internal anti-freeze protection is disabled when connected to
an IntelliTouch system. Freeze protection is provided by selecting YES at the ON WITH FREEZE
portion of the IntelliTouch's appropriate circuit function menu. To re-enable the IntelliFlo's internal
anti-freeze protection, the power to the drive must be cycled off then back on.

Blocked system:

Detects a blocked suction line. This alarm resets automatically after 30 seconds

and the pump restarts.

System service soon:

Alerts the operator that the pump discharge pressure has reached the Clean

Filter Pressure as setup in the Filter Menu. The filter status will be displayed as 100%. The yellow
warning LED will be on until a backwash cycle is operated. The IntelliFlo will automatically reduce
speed as necessary to not exceed the Clean Filter Pressure.

Over current:

Indicated that the drive is overloaded or the motor has an electrical problem. The

drive will restart 20 seconds after the over current condition clears.

Over voltage:

Indicates excessive supply voltage or an external water source is causing the pump

and motor to rotate thereby generating an excessive voltage on the drives internal DC bus. The
drive will restart 20 seconds after the over voltage condition clears.

Suction Blockage

When something blocks the suction or the pump fully it will shut off immediately (within 1 second). It will
also shut off after a few seconds of dead heading with the same alert. The unit will come back on in 30
seconds and ramp up slowly. This function should be tested with all new installations by directing the flow to
one suction and covering it with a piece of material other than someone’s hand. This alert is deactivated in
Manual mode.
