Sun Pumps SJT10-120BL - Manual (Page 4)

2.1 Controller Features
1. Current boosting for matching the load requirements of the pump.
2. Voltage regulation of the solar electric array at its maximum power point. (MPPT)
3. Over-current protection via integrated electronic circuit breaker.
4. Reverse polarity protection (10 amperes maximum) on the input terminals.
5. Voltage and current limiting to pump motor.
6. Transient protection and surge suppression.
7. Adjustable output motor power control for precision output flow.
8. System ON/OFF switch.
9. LED indicators; 1. Power In, 2. Motor Run, 3. MPPT, 4. RS Stop, 5. Low Power, 6. Over-Current, 7. Fault Condition.
10. Weather resistant powder coated, die cast aluminum enclosure with a hinged door.
11. Rising clamp screw terminal blocks – no fork terminals required.
12. Remote switch interface – float switch or remote shutdown –Normally Open or Normally Closed, user selectable.
13. Sensor and sensorless “Low Water” circuit
14. Low Power Shut Down circuit
2.2 Application
The only application the PCA-BLS series controllers are designed for is the interface between a solar module array and SunPumps
Sensorless Brushless DC motors.
No other applications or DC power sources are recommended or warranted unless written approval is provided by the
SunPumps factory.
3.0 Installation and Operation
The following sections are outlined in a step-by-step format to guide you through the installation and configuration of an SJT series
pump and PCA series controller. The procedure for installing the SJT shallow well jet pump is the same as any standard AC jet pump.
Any licensed pump contractor will be familiar with the proper installation procedures. The installation and operation should be in
accordance with local regulations, accepted codes of good practice and common sense. This pump should be installed by a licensed
professional pump installer.
Before installing any pump system read all product manuals then review all system components to become familiar with the
physical and electrical layout. Check all equipment for any product damage. Refer to applicable figure(s) as a guide during the
installation. Controller door must be closed during normal operation.
Warning
Reverse polarity on a panel system capable of producing over 10 amps will result in non-warranted product
damage. Please check polarity before connecting power to the controller.
This controller is for SunPumps Sensorless Brushless DC Motors only. Do not use this controller on AC,
Brush-Type or Sensor Type Brushless DC motors. Damage to the controller and/or motor will result.
3.1 Location
As the majority of system installations vary greatly, only general comments can be made as to location. Prior to installing the system, it
is suggested to make a system layout plan. During the system layout, take into consideration any potential shading of the solar electric
modules, wire runs, wire size, conduit runs, trenching, controller accessibility, tank location, pump head etc. Shading even a small
portion of the array can reduce the output of the entire array and thus reduce or completely stop the output of the pump. There is no
substitute for a good plan! Always follow State and Local Building Codes.
The PCA-series controller can either be mounted indoors or outdoors. Locate all system equipment as close as possible to each other.
For top of pole mount racks, the controller is usually mounted on the north side (shaded side) of the mounting pole. The controller must
be mounted in a vertical position for proper cooling and to keep the electronics dry. The pole should be located close to the well (bore
hole). This general physical layout is conducive to clean installation both aesthetically and electrically.
