Good day everyone! Can anybody explain how the electronic flow switch with four (4) wires connection in 30XA Chiller works and how it can be troubleshoot to ascertain wether it's defective or still ok? May God bless you all!

Hi Okonedo
With the little info I have, as far as I can make out there should be an input on Terminal 7 of the Master controller.
I cannot make out whether it is volt free or low voltage?
But the switch makes or brakes an input into term 7.

Thank you very much Mr Grizzly. I really appreciate your time and effort. I will check the terminal 7 on the main board.
