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
➌
If the “OPEN” or “SHORT” recurs on the original station,
the controller’s internal circuitry may need service.
➍
If the “OPEN” or “SHORT” moves to the new station, check
the valve’s solenoid and field wiring.
•
Loose or corroded wire connections on the controller’s
terminal strip or at the valve solenoid
•
Malfunctioning components on the controller’s internal
circuit board
Troubleshooting Opens and Shorts
To troubleshoot a valve station identified as “OPEN” or
“SHORT:”
➊
Make sure the valve’s station wires are securely connected
to the controller’s terminal strip.
➋
If the wires are securely connected, move the station’s wires
to a station that passed the RASTER. Then re-start the test.
