Troubleshooting; Alerts And Warnings - Pentair INTELLIFLO VSF Installation And User Manual

Always disconnect power to the IntelliFlo VSF Variable Speed and Flow Pump at the circuit breaker and disconnect the communication
cable before servicing the pump. Failure to do so could result in death or serious injury to serviceman, pool users or others due to
electric shock. DO NOT attempt to adjust or service without consulting your dealer or a qualified pool technician. Read the entire
Installation & User's Guide before attempting to use, service, or adjust the pool filtering system or heater.

Alerts and Warnings

The IntelliFlo VSF Variable Speed and Flow Pump displays all alarms and warnings on the control panel display.
®
When an alarm or warning condition exists, the corresponding light will be lit on the display.
In the event of an alarm: The alarm light " " will illuminate and all control panel buttons will be disabled until the
alarm is cleared. Pressing the Reset button will clear the alarm once the fault condition has been resolved.
In the event of a warning: The warning light " " will illuminate, but the pump will continue to run. The speed, flow
or pressure limit that is causing the warning must be adjusted in order to correct the warning.
Note: The pump will not start if the impeller is rotating.
Power Out/OFF
The incoming supply voltage is less than required. 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 Failure
If the pump is not defined as primed within the "Max Priming Duration" it will stop and generate a "Priming Alarm"
for 10 minutes, then attempt to prime again. The "Max Priming Duration" is set by the user on the priming menu
as discussed on page 19. If the pump cannot prime within five attempts it will generate a permanent alarm that
must be manually reset.
Overheat
If the drive temperature gets above 54.4° C (130° F) the pump will slowly reduce speed until the over temperature
condition clears.
Thermal Mode
When active, the motor will run at the preset RPM until the drive internal temperature increases above the
minimum. The pump's internal thermal protection is disabled when connected to an automation system.
Thermal protection is provided by selecting YES at the ON WITH FREEZE portion of the circuit function menu
in the IntelliTouch ® Control System. To re-enable the internal thermal protection, the power to the drive must
be cycled off then back on. IMPORTANT: See explanation of Thermal Mode on page 20.
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 buss. The drive will restart 20 seconds after the over
voltage condition clears.
Internal Error
Indicates that the self-monitoring motor control software has encountered an error. Clear the alarm and restart the
pump. If this alarm persists, contact Pentair Technical Service at 1-800-831-7133.
Speed Limit (Warning)
The pump has detected that it has met the maximum allowed speed set in the Min/Max menu. The pump will
continue to run, but it will not achieve the desired speed.
Pressure Limit (Warning)
The pump has detected that it has met the maximum system pressure set in the Min/Max menu. The pump will
continue to run, but it is not achieving the desired flow rate or speed because of the pressure limit. The feature
is enabled by default while running a program at a constant flow rate, but must be enabled manually if the user
wants the drive to monitor maximum pressure while running a constant speed program.
Flow Limit (Warning)
The pump has detected that it has met the maximum flow rate set in the Min/Max menu. The pump will continue
to run, but it is not achieving the desired speed because it is running at the maximum flow rate. The Maximum
Flow can be set in the Max/Min menu. This feature must be enabled in the Min/Max menu to be active while
running a speed program.
