PW2000 User Instructions
The purpose of the valve finding test is for locating operational irrigation valves operated by
24 VAC solenoids. Since all valves and installations are not identical, results may vary. It is
recommended that continuity and resistance checks be performed before continuing with the
valve finding test.
1. Turn off the water source to the valves
2. Relieve the water pressure from the system if needed
3. Disconnect the common wire going to the valves from the controller common terminal
4. Connect the black short lead to the controller common terminal
5. Connect the black long lead to the common wire going to the valves
6. Activate the output of the valve to locate
7. Locate the valve by the loud chattering of the solenoid
•
Only one valve can be on the circuit being tested
•
New valves should be electrically cycled to reduce initial internal mechanical friction
•
The water source for the value should be turned off during testing and the water pressure
should be released
•
Maximum total circuit resistance: 75Ω at 24 VAC
•
Minimum voltage: 24 VAC at 75Ω
Note:
The results for each may vary depending on the soil conditions, installation method of the wire,
and proper grounding of the controller and power supplies.
Most tests will not function properly when using latching solenoids. The only tests that will
function properly regardless of the type of solenoid are the input power check at the controller,
the blown fuse test, and the relay coil and wire test. By connecting a 9-Volt battery to the
station wires instead of the controller output terminals, the wire identification and broken wire
check tests can be performed on a system.
