1.1 Features
System Diagnostics
The PDS23 solar pump controller continuously monitors system performance and
detects a variety of abnormal conditions. In many cases, the controller will
compensate as needed to maintain continuous system operation; however, if there
is high risk of equipment damage, the controller will protect the system and display
the fault condition. If possible, the controller will try to restart itself when the fault
condition subsides. See Diagnostics and Troubleshooting section for a list of Fault
Codes and corrective actions.
Motor Soft-Start
Normally, when there is a demand for water and power is available, the PDS23
solar pump controller will be operating. Whenever the PDS23 solar pump
controller detects a need for water, the controller always “ramps up” the motor
speed while gradually increasing motor voltage, resulting in a cooler motor and
lower start-up current compared to conventional water systems. Due to the
controller’s soft-start feature this will not harm the motor.
Over Temperature Foldback
The PDS23 solar pump controller is designed for full power operation from a solar
array in ambient temperatures up to 45 °C. In excess of 45

，
the controller will reduce output power in an attempt to avoid shutdown.
Full pump output is restored when the controller temperature cools to a safe level.
Level Control Switch
The PDS23 solar pump controller can access two water level switch detects
remotely control the pump automatically. Level switch for PDS23 solar pump
controller is optional, not mandatory.
