9.0 Set FVS (Flow Verification System)
Used to monitor pump output. If pump does not dispense fluid when pump
head rotor is turning, pump will go into an alarm mode and stop pump. Blue-
White offers a flow verification sensor that can easily attach to fitting on pump.
Default settings: 000 (off)
Navigate to Set FVS menu by pressing UP and DOWN arrows at the same
time, then select Input Setup, then Set FVS.
Press UP or DOWN arrow to set the FVS delay time in seconds.
Press START to save changes and exit FVS screen.
Flow Verification System (sensor sold separately)
Flex-Pro is equipped with a Flow Verification System which is designed to stop
pump and energize a 6 amp relay in event sensor does not detect chemical
during pump operation. This could indicate a clogged injection fitting, empty
chemical solution tank, worn pump tube, loose tubing connection, etc.
To allow pump to clear any gasses that may have accumulated during stopper
operation (such as with chlorine), an alarm delay time value from 1-255
seconds must be programmed (An alarm delay value of 000 seconds disables
FVS system).
If FVS alarm occurs, pump will stop, send an external signal (if setup), and
screen will flash FVS with an alarm icon.
To clear FVS alarm, you must press START button or re-cycle power (unplug
power to pump, then plug back in).
Install FVS Flow Sensor - Flow Verification Sensor (FVS) should be installed
on the inlet (suction) side of the pump tube. Sensor includes a PVC tubing
insert, located inside sensors female thread connection, that is designed to
seal sensor onto pump tube inlet adapter. Thread sensor onto pump tube until
tubing insert is snug against pump tube inlet fitting - do not over-tighten.
