Controller Wiring Lab

CONTROLLER WIRING Service Lab Students: ______________________________ ________________________________ ___________________________________ Controller Type:________________ Model #:______________ Date:_____ Follow the step by step instructions below. Have an Instructor / IA approve your work before dismantling your system. 1. Measure out enough common (white) and control (any color) wire to reach from your designated controller (through the hole in the bottom of the controller) to the furthest control valve, plus 18". 2. Strip the ends of all your wires approx. 1" for double “braids” and .5" for all single connections. 3. Make sure the controller is NOT plugged in. 4. Open the controller and expose the “terminal strip”. Hook up Common (white) wire to “C” terminal. Hook up Control (signal) wires to designated terminals. 5. At Sprinkler/Valve #1, hook together the exposed Common wire leading back to the controller with a short length of Common wire leading to Sprinkler/Valve #2. “Braid” the wires together with one of the solenoid wires from Sprinkler/Valve #1. Connect the other common wire end (of your short length) to the other Sprinkler/Valve solenoid. ( option to attach both valves and common wire together) 6. Connect the #1 control wire to the remaining solenoid wire at Sprinkler/Valve #1. Now connect control wire #2 to the other solenoid wire at Sprinkler/Valve #2. (alternately for Steps 4 and 5 you can attach 1 solenoid wire from each valve to end of the common wire) 7. Put marettes on all exposed connections. For this exercise we are using indoor marettes. DO NOT USE THESE MARETTES IN A REAL INSTALLATION. You will need waterproof marettes. 8. Plug the controller into the 110V power source and install a 9 volt battery. Set Time/Day on the controller, following the instruction booklet. 9. Set Sprinkler/Valve #1 to run for 1 minutes, and Sprinkler/Valve #2 to run for 1 minutes.The valves will vibrate when they’re running. If your program times are every 15 minutes, you can adjust the program time so you don’t have to wait 15 minutes for your valve to turn on. 10. Ask your instructor or IA to check your work before dismantling your system. INSPECTION _______________
