Sun Pumps SIJ 2.2-1300P-135 BL - Manual (Page 3)

1.0 Introduction
Thank you for selecting a SunPumps SIJ series solar plunger pump system. The SIJ series pump and PC 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 high pressure and high head pumping applications
such as pumping up high hills or injection water or chemicals into a high pressure system. The operating pressure can be as
high as 2000 PSI, depending on the pump model.
SunPumps SIJ series systems are solar powered, triplex plunger pumps, utilizing a sensorless brushless DC motor. The
brushless DC motors are constructed of high quality, anodized, die-cast aluminum and the controller is mounted in a powder
coated, die cast, NEMA 3R enclosure. These pumps are designed specifically for water delivery in remote locations.
The PCA-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 SIJ 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 PCA-BLS-M2. Personal injury or other damage may result.

Do not exceed the voltage rating of the controller.

Do not start or 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.

Verify wiring connections between the controller and the motor before starting the pump.
2.0 Product Overview
The SunPumps PCA-BLS-M2 and PCC-BLS-M2 series controllers were designed specifically for SunPumps Sensorless
Brushless DC motors. When properly installed and configured, the features incorporated into this stand-alone system will
control and protect your pump system permitting many years of dependable, trouble free service. SunPumps has produced
multiple versions of this controller. The notable differences 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 All controller models have the same basic 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.
