TROUBLESHOOTING GUIDE
1. For any problem,
check the basics
first.
A. Is controller plugged in and properly programmed?
B. Is master shut off valve open?
C. Is flow control on valve in an "open" or "flow" position? Not all models have this fea-
ture. Check the instructions that came with your valve, or see "How to Operate" section
of this packet.
D. Are water pressure and flow rate adequate for your particular valve model? (Check
the instructions that came with the valve or call us toll free at 1-800-RAIN-BIRD for the
requirements of your particular Rain Bird valve model.) If your pressure is too low, in-
vestigate these causes:
Pressure drain from washing machines, showers, etc. or broken pipe
Master shutoff valve not fully open
Blockage in main supply line; to repair, cut main line, flush line, and repair cut
Too many heads on line; redesign system layout to reduce the number of heads op-
erating at once
Inadequate pressure at the point of connection
E. Is valve in "Manual Off" position? See "How to Operate" section of this packet.
F. If your system is supplied by a pump, is it working?
SYMPTOM CAUSE DIAPHRAGM VALVE REMEDY
A. Check the Basics
as in No. 1 above
If all basics check out, see if the valve will work manually. On some
models you will need to turn the solenoid 1/4 turn counterclockwise. On
other models, turn the screw in the center of the bonnet (water should
spray out of the top of the valve temporarily). Check your valve operat-
ing instructions or refer to section entitled "How to Operate," in this
packet of information. If the valve works manually, go on to step 2-B. If
the valve doesn't work, go on to step 2-D.
2. Valve won't turn on
with controller
B. No power between
controller and valves
Check by pressing the "Manual Start" button of the controller and ad-
vance to the desired station. Attach a circuit tester (voltmeter) to the
common terminal and the station terminal of the controller. If you do not
get a 24-30 volt reading, the problem is in the controller.
Check for shorted or broken wiring. Follow directions as above, except
attach voltmeter to common wire and station wire nearest valve. If you
do not receive a 24-30 volt reading, replace or repair wiring.
C. Solenoid burned
out or clogged
The solenoid should make a distinct "click" when activated. If controller
and wiring check out, try unscrewing the solenoid and swapping it with
a nearby valve of the same model. Using the "Manual Start" on your
controller, check the station again to see if the borrowed solenoid acti-
vates the valve. If so. replace solenoid. If not check 2-D.
