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.
