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