RAPID STATION TEST ROUTINE — RASTER™
The RASTER is available on indoor and outdoor versions of
Rain Bird’s ESP-LX+ and -LXi+ controllers.
Introduction
Rain Bird’s RA pid S tation TE st R outine (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 valve’s 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 controller’s internal circuitry.
