Sun Pumps SCB-10-150-120 BL - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps SCB series solar pump system. The SCB 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.
SunPumps SCB series pumps are multi-stage centrifugal, three phase DC powered, surface pumps
constructed of high quality stainless steel. These pumps were designed specifically for water delivery in
remote locations.
The PCC-BLS series controllers are microprocessor based solid state DC power converters designed as the
interface between a solar module array and a three phase sensorless brushless DC pump motor. The
purpose of the controller is to operate the high efficiency, high reliability DC motor and maximize the total
daily water output while providing protection for the pump as well as providing an interface with other
related pumping system equipment.
Although these SCB series pump systems are easy to install, please read this manual to become
familiar with the pump and controller features, functions, connection points and various
configurations. For future reference, keep this manual and other relevant product information in a
safe place.
PRECAUTIONS
• Safety First – Always understand what you are doing when working with any form of
electricity. Guessing at something is not worth the potential of product damage and/or
severe personal injury.
• Shut down all power when working on the system. Do not feed live wires into the PCC-BLS-
M2. Personal injury or other damage may result.
• Do not exceed the voltage rating of the controller.
• Do not run the pump dry.
• Do not splash water on the controller when the cover is open.
• Mount the controller in a shaded, well vented, vertical position.
• Installation of this system should be done by a licensed Pump Contractor.
2.0 Product Overview
The SunPumps PCC-BLS-M2 series controllers were designed specifically for SunPumps sensorless
brushless three phase DC pumps. When properly installed and configured, the unique features incorporated
into this stand-alone system will automatically control and protect your pump system permitting many
years of dependable, trouble free service. SunPumps has produced multipls versions of this controller. The
noteable differences between the two are certain set points and electrical characteristics which are detailed
in the table below.

1 Min Voltage is the minimum voltage which the unit must see in order to start the pump. If this voltage is not obtained,
the unit will not attempt to start the pump. Voltages lower than this will not hurt the unit.
2 Both controller models have the same operating features, functionality and setup. Voltage and power tolerances are
the only differences of concern to the end user. This manual will only differentiate when necessary for clarity.
