PDS33 Series

1.1 Features

System Diagnostics
The PDS33 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 PDS33
solar pump controller will be operating. Whenever the PDS33 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 Monitoring
The PDS33 solar pump controller can be operated at full power when the ambient
temperature reaches 45 °C. At temperatures above 45 °C, the controller reduces the
carrier frequency and maintains operation as much as possible.
Level Control Switch
The PDS33 solar pump controller can access two water level switch detects
remotely control the pump automatically. Level switch for PDS33 solar pump
controller is optional, not mandatory.
