Page 5: Overview
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 pages 20 &... -
Page 6: How It Works
A leading cause of pump motor failure is the stress applied to the motor during a full voltage start-up. The Fhoton™ Drive variable speed operation ramps up the speed smoothly, which reduces starting stress. -
Page 7: Features
Level Control Switch(es) Level control switch(es) can be wired into the Fhoton™ Drive for water level control. This is optional and is not required to run the Fhoton™ Drive. The controller can be used with none, one, or two control switches. This provides the user maximum adjustability when using the Fhoton™... - Page 8 35 Hz (rotor speed) and above, the electronic dry well protection algorithm is active. If the motor load falls below the built-in, dry well trip level while the rotor speed exceeds 35 Hz for a period of 3 seconds, the Fhoton™ drive will halt the motor. The red LED will begin a 1 flash sequence and continue this flash sequence for a duration of 10 minutes.
- Page 9 Open Phase (Open Circuit) The Fhoton™ Drive monitors each phase current to the motor. If one of the phases is near zero amps for a duration of 1 second, the Fhoton™ drive will halt the motor. The red LED will begin a 5 flash sequence and continue this flash sequence for a duration of 3 cycles.

2. The electronics inside the Fhoton™ Drive are air-cooled. As a result, there should be at least 18" (45.7 cm) both above and below to allow for air flow and proper cooling. If the Fhoton™ Drive is mounted under the PV solar array, make sure that it is at least 18"... -
Page 12: Mounting Procedure
ALLOW FIVE MINUTES FOR DANGEROUS INTERNAL VOLTAGE TO DISCHARGE BEFORE REMOVING FHOTON™ DRIVE COVER. The Fhoton™ Drive is not protected against a “bolted” short to ground at the motor cable terminals. Ensure that the motor leads have been checked for a possible short to ground BEFORE operating the drive. -

Figure 4: DC Wiring Connection CAUTION Only connect a photovoltaic solar array to the DC input of the Fhoton™ Drive. This controller is suitable for use on a circuit capable of delivering not more than 5,000 RMS symmetrical amps, 850 V DC maximum. -
Page 14: Flow Switch Wiring Connections
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. -
Page 15: Flow Switch Plumbing Installation
Flow Switch Plumbing Installation WARNING Hazardous Pressure Present: Pressure at the flow switch must be limited according to the water temperature that the flow switch will see in service. Note that this includes the temperature that the water could reach due to heating by the surrounding environment. -
Page 16: Pump/Motor Wiring Connections
Control Switch Wiring Connections (Optional) The Fhoton™ Drive can be operated with control switches to control the ON/OFF pumping range. Use a normally closed low-voltage control switch with a contact rating suitable for instrumentation use (i.e. Max: 24 V 15mA): 1. -
Page 17: Control Switch Operation
Zero Control Switch Operation Lastly, the Fhoton™ Drive may be configured to not use a control switch. In this configuration the Fhoton™ Drive will always try to run the motor and pump water as long as there is sufficient power from the solar array, leave the jumper (on “J8”) in place, located immediately... -
Page 18: Start-Up And Operation
After all appropriate connections have been made, place the cover on the Fhoton™ Drive, then apply power to the controller. A steady green light in the center of the cover indicates that the Fhoton™ Drive has DC power connected. No light can indicate that the polarity is reversed, assuming sufficient DC voltage is available. -

* Maximum cable length from the drive to the motor is 1000 ft (305 m). External filtering is required for motor cable lengths exceeding this maximum distance or nuisance tripping might occur. Contact Franklin Electric for additional assistance with external filtering for distances larger than 1000 ft (305 m). -
