PDS51 Series
- 10 -
solar water pump controller displays the fault type through the display on the front cover of
the controller, and can automatically reset the normal faults.
We have optimized the pumping function of the PDS51 solar water pump system under
the condition of poor solar array input power supply as follows:Internal diagnostics allow
for lower input voltages.Whenever possible, the controller will maximize the output of the
solar array to drive the water pump.Provides users with an easy-to-use interface for
enhanced configurability and remote monitoring of the system.
2.3 Protect Functions
Electronic monitoring enables the controller to monitor the system and automatically
shut down when:
1
The well level is low
2
The water tower
（
or water tank
）
is full of water
3
The pump is blocked or overloading.
4
High voltage surge
5
Low voltage input
6
Motor phase loss
7
Short circuit
⑧
Controller inner overheating
NOTE: This controller provides overload protection for the motor by preventing motor
current from exceeding rated current and limited load operation at low water levels. The
controller does not provide motor overheat detection.
