64 ESP-LX+ & LXi+ Installation, Programming, & Operation Guide
Diagnostic Circuit Breaker
If the ESP-LX+ or ESP-LXi+ controller detects an electrical
short circuit on one of the sprinkler system’s station wires or
valve solenoids, the controller automatically shuts off the
station with the fault. After shutting off the shorted station, the
controller advances to the next working station in the program.
Every three seconds, the LCD displays the problem station’s
number and the message “FAULT.” The Fault LED will also flash,
indicating a station short circuit.
The controller will continue to run each operable station in the
program. As each station is running, the controller (at an
alternate 3-second interval) displays the working station’s
number and run time remaining (when the programming dial is
set to the AUTO position).
When the controller finishes the program, it will continue to
display the problem station’s number and the “FAULT” message
and the Fault LED will continue to flash.
After the program finishes, you should isolate and repair the
short circuit. Short circuits occur most frequently in the valve
solenoid (the plastic-encapsulated coil on the valve with the two
wire leads), or in the wire connectors to the valve leads.
After you find and repair the short circuit, press the “Clear
Fault” button to clear the “FAULT” message from the display
and stop the flashing Fault LED. Then you may wish to operate
the station manually to make sure it works properly. (See “Run
Station(s) Manually” on p. 35).
The LCD display shown below indicates that the controller has
detected a short circuit on station 2.
