Test Shorted Paths
The ESP-LXIVM controller can quickly determine if faults are present
on the 2-Wire path.
Although finding the exact location of issues in the field often
requires some amount of in-the-field troubleshooting with a clamp
meter, the controller has some built-in features to help you narrow
down the possible issues.
Before beginning 2-Wire diagnostics, it may be helpful to take the
following steps to eliminate possible other causes:
• Review Station Priorities: The LX-IVM controller can be config-
ured to irrigate based on the station priorities. If multiple pro-
grams are running, higher priority stations will irrigate prior to
medium priority stations, and medium priority stations will irri-
gate prior to lower priority stations. See "Set Priority" on page
29 for more details.
• Run Test All Stations: The Test All Stations manual test will take
priority above pre-programmed irrigation and allow you to deter-
mine which stations are working properly. See "Test All Stations"
on page 101 for more details.
