Guide for troubleshooting for PS2 pump controller
6.2. How to check whether there is a short circuit on the controller board input?
• Write down the input voltage on the
terminal clamps of the PS2 controller
• Disconnect the PV Generator from the
controller
• Check the voltage of the PV Generator
If the voltage of the PV Generator raises to the expected level, replace the Power-Board. If the
voltage is still close to zero, the defective product is not the PS2 controller. Please check the PV
Generator completely (wiring/each module Voc, Isc/…).
