Overview; Descriptions And Features - Franklin Electric Fhoton Drive Guide D'installation

Overview

The Fhoton™ Drive is a variable speed motor drive designed to run a Franklin Electric three-phase submersible induction motor. The
Fhoton™ Drive provides water to remote locations by converting high voltage, direct current from a solar array into alternating current to
run a standard AC submersible motor. The controller provides fault detection, motor soft start, and speed control. The Fhoton™ Drive is
designed to provide these features with the plug and play ease of installation similar to a single-phase control box.
The Fhoton™ Drive is designed with the high standard of reliability expected of Franklin Electric products. The controller drives the pump
and motor to deliver water even under adverse conditions, reducing output as necessary to protect the system components from damage,
and only shutting down in extreme cases. Full operation is restored automatically whenever abnormal conditions subside.
Inspection
Before you begin, receive and inspect the Fhoton™ Drive unit. Verify that the part number matches what was ordered and that no damage
has occurred during transit.

Descriptions and Features

The Fhoton™ Drive system controller controls a Franklin Electric 4-inch three-phase motor driving a 4-inch submersible centrifugal pump
powered by a DC solar array.
The Fhoton™ Drive continuously monitors system performance and incorporates a number of features for pump system protection. In the
event of a fault, the Fhoton™ Drive will indicate the type of fault by a flashing red LED. (See Fault Codes and Troubleshooting on page 21).
The Fhoton™ Drive system is optimized for pumping under adverse input power conditions unique to solar arrays.
• Internal diagnostics will tolerate a lower input voltage.
• Whenever possible, the controller attempts to regulate the pump load in an optimized manner for maximum power transfer from the
solar array.
The controller construction is ruggedized for hostile environmental conditions.
• The case is constructed of heavy-gauge aluminum to resist rain and animal intrusion.
• The seals are designed for NEMA 4 (IEC rating IP66), (dust tight, withstands directed jets of water).
• For maximum protection against dust, there is no external cooling fan or other external moving parts.
