IntelliFlo Pump Alarms and Warnings
®
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 pump menu (and IntelliCenter menu, see
page 62). 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 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.
• Freeze Protection: When set to ON, the pump motor will run at a user defined
speed. Note: The IntelliFlo pump's internal anti-freeze protection is disabled
when connected to the automation control system. To re-enable the IntelliFlo
pump's internal 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 green warning LED will be on until a
backwash cycle is operated. The IntelliFlo pump will automatically reduce
speed as necessary to not exceed the Clean Filter Pressure.
Note: The IntelliFlo VS pump alarm and warnings are indicated by flashing LEDs
on the pump's control panel. For example, if a "Drive Temperature" warning
occurs, the LED will blink two times, then Off, then blink two times. This
sequence is repeated until the condition is cleared.
• Warning condition: If a warning condition occurs the pump will continue to run
but at a reduced speed. The Green LED displays a sequence of blinks to indicate
which alarm or warning has occurred.
• Alarm condition: If an alarm condition occurs the pump will stop running. The
red LED flashes continuously to indicate the presence of an alarm. The alarm
LEDs will reset when the condition clears.
