Troubleshooting Open and Shorted Valve Circuits

Open Circuits

An “OPEN” condition reported by the RASTER indicates a
complete break in the current flow between the controller and
the valve.
NOTE: The RASTER will display an “OPEN” condition if
no valve solenoid is connected to the controller
station. This is normal, and the system does not need
service.
Open circuits can be caused by:
Malfunctioning valve solenoids
•
.ield wires that have been cut or pulled loose
•
Loose wire connections on the controller’s terminal strip or
•
at the valve solenoid
Damaged components on the controller’s internal circuit
•
