Sun Pumps MTR BLM-SB-103S-120Y - Manual (Page 3)

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.
SunPumps SCS series pumps are multi-stage centrifugal, DC powered, submersibles 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 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 SCS series pump systems are easy to install, please read this manual to become
familiar with the 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 may cause product damage and/or severe personal injury.
• Shut down all power when working on the system.
• Do not attempt to feed live wires into the PC-series controller. Product damage and/or
personal injury may result.
• Do not exceed the voltage rating of the controller.
• Do not set the controller to exceed the power rating of the motor. See 3.6 Controller Settings.
• 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 SCS-series,
Sensorless Brushless DC submersible 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 multiple versions of
this controller. The 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.
