C3 C3
5.4 FVS - Flow Verification System
The C3 is equipped with a Flow Verification System which is designed to stop
the pump and provide a contact closure output in the event the sensor does not
detect flow during pump operation. This could indicate a clogged injection fitting,
empty chemical solution tank, loose tubing connection, etc.
To allow the 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
the FVS system).
- (sensor sold separately)
Install the FVS Flow Sensor - The Flow Verification Sensor (FVS) should be
installed on the outlet (discharge) side of the pump head valve.
Connect the red/white, black, and white wires from the sensor to the red, black,
and yellow wires located in the pump’s junction box.

Contact Closure Alarm Output - A contact closure output (relay) is provided
with the FVS system. The relay can be configured for normally open (factory
default) or normally closed operation by properly positioning the connector plug
on the circuit board .
