Short Circuits - Rain Bird ESP-6LX+ Installation, Programming, And Operation Manual

Short Circuits

A “SHORT” condition reported by the RASTER indicates an
unintended re-routing of current flow somewhere between the
controller and the valve.
Short circuits can be caused by:
Shorted valve solenoids
•
Nicked or “skinned” field wires
•
Troubleshooting Opens and Shorts
To troubleshoot a valve station identified as “OPEN” or
“SHORT:”
Make sure the valve’s station wires are securely connected
to the controller’s terminal strip.
If the wires are securely connected, move the station’s wires
to a station that passed the RASTER. Then re-start the test.

Malfunctioning components on the controller’s internal
•
circuit board
If the “OPEN” or “SHORT” recurs on the original station,
the controller’s internal circuitry may need service.
If the “OPEN” or “SHORT” moves to the new station, check
the valve’s solenoid and field wiring.
