IntelliFlo VSF Alerts and Warnings
Pressure Limit (Warning): The pump has detected that it has met the
maximum system pressure set in the Min/Max menu. The pump will con-
tinue 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
Power Out/OFF: The incoming supply voltage is less than required. The
drive faults to protect itself from over current. The drive contains capaci-
tors that keep it powered up long enough to save the current run param-
eters. 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 Prim-
ing 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 manu-
ally 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.
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.
