Page 3: Introduction
1.0 Introduction Thank you for selecting a SunPumps SCS series solar pump system. The SCS series pump and PCC series Sensorless Brushless DC - pump controller are the key components to high quality solar powered pumping systems. Their stand-alone, pollution free and low noise operation makes them an ideal solution for remote homes, irrigation projects, and wildlife and stock watering without violating the environment. -
Page 4: Controller Features
The following sections are outlined in a step-by-step format to guide you through the installation and configuration of an SCP series pump and PCC series controller. The procedure for installing the SCP series pool pump is the same as a standard AC pool pump. Any licensed pump contractor will be familiar with the proper installation procedures. -
Page 5: System Design Basics
Refer to a DC wire loss chart for proper sizing. It is recommended to keep the voltage drop under 3%. Refer to the wire sizing guide on the SunPumps web site under Engineering. Never install the controller in direct sunlight. Direct sunlight on the controller may cause over- heating of the controller. -
Page 6: Pump Strainer Basket
Pump Strainer Basket This pump has a basket strainer, sometimes called a “Hair and Lint Pot” located in the front section of the pump volute. Inside this chamber is a basket which must be kept clean of leaves and debris at all times. View the basket through the “See-Through Lid”... -
Page 7: Wiring
Ensure the wire sizes are of adequate diameter (gauge) to minimize voltage drop. Please refer to a DC voltage loss table or call your SunPumps dealer for assistance. Wire gauge being too small will cause excessive voltage losses to the motor and will reduce the flow rate of the pump. - Page 8 Figure 2 Controller Wiring Diagram...
- Page 9 After mounting the controller, switch the controller to the OFF position. If you are using a remote switch, like a float switch, set dip switch 1 to the correct position for the type of switch being used. (“Normally Open” or “Normally Closed”.) If you are not using a remote switch leave switch 1 off.

This feature is designed for use in the submersible SCS systems with the ground wire installed. For use with the SCB or SCP systems contact SunPumps for assistance. The “LW” terminal of the controller should be attached to a low water sensor electrode which is mounted in your tank or well. -
Page 12: Application
Remote Switch The Remote Switch interface can serve as an automatic system shutdown when used with a water storage tank mounted float switch, a pressure switch or it can also serve as a manual system shutdown with a remote system ON/OFF toggle switch. The remote logic circuit allows the use of standard “Pump-Up or Pump Down”... - Page 13 Output Power Limit Circuit (Motor Speed Control) The Output Power Limit Control circuit is used to control the speed of the pump motor and thus the flow rate of the pump. It is primarily used for low producing wells where the pump output is matched to the production rate of the well.

Using this trouble shooting guide as your first resource when your system is not working properly can save you valuable time in getting your system fully functional. - Page 16 displays “GF FUSE OPEN” the ground fault fuse has been blown. Check your system for ground loops and replace the fuse with a 500 VDC 1A rated fuse. If this does not solve the issue, contact Sun Pumps for further assistance. Check for proper dip switch settings on your controller.
- Page 17 BEFORE CALLING SUNPUMPS If at all possible when calling Sun Pumps for technical support there are a few things which will help to speed up the process and help us determine the cause of and solution to the system failure. The best way to get help is to call while you are physically at the location of your pump, have good sunlight, and have a multimeter and a screwdriver with you.
