RAPID STATION TEST ROUTINE RASTER
The RASTER is available on indoor and outdoor versions of
Rain Birds ESP-LX+ and -LXi+ controllers.
Introduction
Rain Birds RApid Station TEst Routine (RASTER) lets you
diagnose and troubleshoot field wiring, solenoid, and controller
problems quickly and easily.
The RASTER sends an electric signal to each valve terminal on
the controller and then displays the valves current operating
condition. Results appear in the easy-to-read digital display.
The RASTER checks each station and displays one of three
results:
1. OPEN The circuit between the controller and the valve
is open; i.e., no current is flowing.
2. SHORT The circuit between the controller and the valve
has a short; i.e., current is flowing on an
unintended path.
3. FAIL The controller was unable to send the test signal
to the stations. This indicates a possible
problem with the controllers internal circuitry.
