IntelliFlo VS 3050 and IntelliFlo VSF+SVRS
Warning and Alarm Conditions
The IntelliFlo VS 3050, IntelliFlo VS+SVRS and IntelliFlo VSF+SVRS alarms and warnings are
indicated by flashing LEDs on the 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 be continue to run but at a
reduced speed. The Green LED executes a sequence of blinks to indicate which alarm or
warning has occurred.
• Alarm condition: If an alarm condition occurs the pump will drive stop running. The red LED
flashes continuously to indicate the presence of an alarm. The alarm LEDs will reset when the
condition clears.
