Page 6: How It Works
How It Works The Franklin Electric SubDrive300 is designed to be part of a system that consists of only four components: A. Standard Pump and Franklin Electric Motor. B. SubDrive Controller. C. Small Pressure Tank (for tank size, see Table 3). - Page 7 Motor Soft Start Normally, when there is a demand for water, the SubDrive300 will be operating to accurately maintain system pressure. Whenever the SubDrive300 detects that water is being used, the controller always “ramps up” the motor speed while gradually increasing voltage, resulting in a cooler motor and lower start-up current compared to conventional water systems.

Page 8: Pump Sizing And Drive Confi Guration
Flow GPM Drive Confi guration The SubDrive300 can also be set up to run a 5 Hp pump if desired, but the larger pump will still produce to the 5 Hp curve and may only be operated with a 5 Hp motor. To operate a different pump size, a DIP switch must be positioned to select the correct pump rating. -
Page 9: Underload Sensitivity For Shallow Wells
Underload Sensitivity for Shallow Wells The SubDrive300 controller is confi gured at the factory to ensure detection of Underload faults in a wide variety of pumping applications. In rare cases (as with certain pumps in shallow wells) this trip level may result in nuisance faults. -
Page 10: Before Getting Started
Use SubDrive300 only with Franklin Electric 4-inch submersible motors as specifi ed in this manual (see Table 1). Use of this unit with any other Franklin Electric motor or with motors from other manufacturers may result in dam- age to both motor and electronics. -
Page 11: Controller Location Selection
Controller Location Selection The SubDrive controller is intended for operation in ambient temperatures up to 125°F (51°C) at 230 VAC input. The following recommendations will help in selection of the proper location of the SubDrive unit: 1. A tank tee is recommended for mounting the tank, pressure sensor, pressure gauge, and pressure relief valve at one junction. - Page 12 CORRECT INCORRECT 4. For indoor or outdoor installations. 5. The SubDrive300 should only be mounted with the wiring end oriented downward. The controller should not be placed in direct sunlight or other locations subject to direct rain or snow. 6. The mounting location should have access to 230 VAC electrical supply and to the submersible motor wiring.

Page 17: Installation Procedure
Installation Procedure 1. Disconnect electrical power at the main breaker. 2. Drain the system (if applicable). 3. Install the pressure sensor and pressure shut-off sensor at the pressure tank tee downstream of the pressure tank (the pressure tank should be between the pressure sensor and the pump). The sensors have a ¼-18 National Pipe Thread (NPT) connection. -
Page 18: Wiring Connections
WARNING Serious or fatal electrical shock may result from failure to connect the motor, the SubDrive300, metal plumbing and all other metal near the motor, or cable to the power supply ground terminal, using wire no smaller than motor cable wires. To reduce risk of electrical shock, disconnect power before working on or around the water system. -

Page 20: Pressure Sensor
12. The pressure sensor communicates the system pressure to the SubDrive300 controller. The sensor is preset at the factory to 50 psi, but can be adjusted by the installer using the following procedure: a. Remove the rubber end-cap (Figure 4A). -
Page 21: Start-Up And Operation
NOTE: Conventional private water systems intermittently fi ll a pressure tank as commanded by a standard pressure switch (e.g. 30 - 50 psi). The SubDrive300 maintains a constant pressure at the pressure sensor up to the maximum capability of the motor and pump. -

Page 26: Underload Smart Reset
Underload Smart Reset If a motor Underload fault condition occurs, the most likely cause is an overpumped or dry well. To allow the well to recover, the SubDrive300 controller will wait 30 seconds to 5 minutes, determined by duration of the previous run time, before restarting the motor. - Page 27 TOLL-FREE HELP FROM A FRIEND Franklin Electric Submersible Service Hotline 800-348-2420...
