ESP-LXME Controller
Wiring Diagnostics
Although nding the exact location of issues in the eld often requires
some amount of in-the-eld troubleshooting, the controller has some
built-in features to help you narrow down the possible issues.
Before beginning diagnostics, it may be helpful to take the following
steps to eliminate possible other causes:
1. Review and Confirm Programs to check station priorities.
If a suspect station isn’t watering as scheduled, the underlying
issue could be programming-related. The ESP-LXME controller
can be congured to operate stations in order of station number
or station priority. If Station Sequencing by Station Priority mode
is enabled and multiple programs are running, higher priority
stations will irrigate prior to medium priority stations, and medium
priority stations will irrigate prior to lower priority stations. See
Conrm Programs in this section for more details.
2. Run a Test All Stations check to ensure valves are working properly.
The Test All Stations manual test will take priority above pre-
programmed irrigation and allow you to determine which stations
are working properly. See Test All Stations for more details.
Raster Wiring Test
The ESP-LXME controller can quickly test to determine if any stations
have shorted or open wires or valve solenoids.
Turn the controller dial to Test All Stations/Check System.
