Sun Pumps PCC-48BLS-M2 - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps battery powered pump system. Sun Pumps battery pumps and PCC series
Sensorless Brushless DC - pump controller are the key components to high quality battery 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 pumps are multi-stage centrifugal or piston, three phase brushless sensorless DC powered, pumps
constructed of high quality parts. 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 battery bank and a three phase brushless sensorless 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. Three
phase brushless DC motors cannot be run from a battery bank without a controller.
Although these PCC series pump controllers 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 PCC-series controller. Product damage and/or personal
injury may result.

Do not exceed the voltage rating of the controller.

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 DC
motors. 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.
Currently SunPumps has only produced one version of this controller. The default set points and electrical
characteristics 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 but may harm batteries. This voltage can be
adjusted. See Input Voltage Threshold Adjustments.

At 64 volts the controller will turn off in overvoltage. 3 Low Battery Voltage
is the voltage threshold which will cause the controller to turn the pump off after 45 seconds. This voltage can be adjusted. See
Input Voltage Threshold Adjustments.
4 Dead Battery Shutdown is similar to note 2 but will shut down the pump immediately. This voltage can be adjusted. See Input
Voltage Threshold Adjustments.
