IntelliFlo VF 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:
•
If the pump is not defi ned 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 25. If the IntelliFlo cannot prime within fi ve attempts it will
generate a permanent alarm that must be manually reset.
Overheat alert:
•
If the drive temperature gets above 54°C, 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. 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 fi lter 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 fl ow to one suction and covering it with a piece of material other than someone’s hand. This alert is
deactivated in Manual mode.
