IntelliFlo Alarms 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.
For IntelliFlo troubleshooting information, see the IntelliFlo 4 Installation and User’s Guide (P/N
350075).
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.
