Flow Switch Wiring Connections - Franklin Electric FHOTON Drive Manual De Instalación

Flow Switch Wiring Connections

The Fhoton™ Drive makes use of a flow switch to protect the centrifugal pump and motor when there is not enough power to generate
proper flow. Use of the flow switch is required for installations to prevent running during deadhead/no flow conditions.
Make sure that the external disconnect switch is off prior to making any connections to the drive.
Connect the cables from the flow switch terminals NO and COM to the Fhoton™ Drive terminal block labeled "FLOW SWITCH" (Figure 5).
If disconnecting flow switch wires, use small flathead screwdriver, or similar tool, to press the orange button above the wire.

CAUTION
Failure to install a flow switch will result in reduced system performance and may result in centrifugal pump and motor damage if
adequate cooling by the surrounding water is not ensured. A flow sleeve is always advised to provide additional cooling in wells larger
!
than 4" (10.16 cm). See the Franklin Electric AIM manual (M1311) for proper cooling flow requirements.
