Testing All Devices
Before you begin troubleshooting a problem, run a Test All Devices from the Test menu. This test
checks all the devices on the two-wire and displays a summary screen of the results.
If the test finds errors with the devices, the error count is listed for each device type. This test
verifies communication and valve currents, biSensor readings, and other device readings, but it
does not make any repairs.
1. Press the Test button. The Test menu displays.
2. Press the  or  button to highlight the Test All Devices option, and then press the OK
button. The Test All Devices screen displays and the test begins.
If any zones or programs are running when
the test is activated, watering will pause for
10 minutes.
When the test finishes, the results display. If
any errors are reported, you can view them in
the list of messages. Refer to Viewing
Operator Messages on page 92.
Troubleshooting the Two-Wire: High Current or Shorted
The first step in troubleshooting the two-wire is to isolate what works from what does not work. A
complex system with many branches in the two-wire path can be difficult to troubleshoot while
everything is interconnected. When a short can be isolated to a single segment of the two-wire
system, or to a single component, it becomes much easier to fix the problem.
In order to isolate the short, you must physically disconnect two-wire segments and components
from the system in a logical manner. Then you can add the two-wire segments and components
one at a time in order to isolate the problem.
As you approach problem solving situations, separate problems into the following categories:
• It has never worked.
• It worked before and now it does not.
For problems that fall into the second category, find out what has changed because these factors
might provide some insight or a place to start looking for solutions.
• Begin by disconnecting half of the two-wire.
• Next, determine whether the system is running properly with just half of the two-wire
connected. If it is, you know that the short is in the other half of the two-wire. If the system
does not run properly, you know that the problem is in the half of the two-wire that is
connected.
• After you have isolated the short to a half of the two-wire, you can start breaking
connections, one at a time, in order to isolate exactly where the problem is.
