Help with pH controller and solenoid
 

Hey so I just got this commercial pH controller and solenoid from a friend for my calcium reactor. But I can't figure out how to get it so that it will energize the solenoid and open! I have the low range limit set, but it won't open. Anyone have any suggestions for where to put the wires from the solenoid?
