Troubleshooting Open and
Shorted Valve Circuits
Open Circuits
When the RASTER
TM
shows an “OPEN” valve circuit,
it indicates a complete break in the current flow
between the controller and the valve.
NOTE: The RASTER
TM
will display an “OPEN”
indicator if no valve solenoid is connected to the
controller station. This is normal and the system
does
not need service.
These are the most common causes of open circuits:
• A malfunctioning valve solenoid
• Field wires that have been cut or pulled loose
• Loose wire connections on the controller’s
terminal strip or at the valve solenoid
• A damaged component on the controller’s
internal circuit board
