IntelliFlo 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: If the pump is not defined as primed within the "Max Priming Time" it will stop and
generate a "Priming Alarm" for 10 minutes, then attempt to prime again. The "Max Priming Time"
is set by the user on the priming menu as discussed on page 14. If the IntelliFlo cannot prime
within five attempts it will generate a permanent alarm that must be manually reset.
• 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.
Note: For IntelliFlo troubleshooting information, see the following manuals: IntelliFlo VF 3050
(P/N 350075), IntelliFlo VS 3050 (P/N 357269) and IntelliFlo VSF+SVRS (P/N 351420).

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.
