S-305DC Solenoids
- Troubleshooting the S-305DC Solenoids
- Verify that the correct solenoid and adapters are being used for the valve in question.
- Verify that the white and red wires from the solenoid are connected to the white and red wire pair on the controller and that these splices are tight, and corrosion free.
- Verify that no water is leaking externally near the adapter, stem, or bonnet.
- Verify that all "O" rings and/or rubber hoses are in place, if in doubt, check the adaptor and the solenoid.
- To test S-305DC solenoid, remove the solenoid from the valve and disconnect the hot and common wires. Verify the solenoid functions properly using a 9-volt battery by briefly touching the wires to the positive and negative contacts. Reverse polarity if nothing happens. Plunger should retract. Reverse polarity to close, (plunger should extend and a sound of the plunger latching should be heard).
- If the solenoid does not function with a 9-volt battery, check the battery. If the problem with the solenoid continues after using a second battery, it should be replaced.
- If the valve is weeping or not closing completely, the adapter being used with the S-305DC solenoid may be loose, cross-threaded, missing an "O" ring, the adaptor sleeve could be damaged, or the valve diaphragm inside the valve could be in need of cleaning or replacement.
- If the valve is not opening completely, the adapter being used with the S-305DC solenoid may be to tight, the adaptor sleeve could be damaged, or the valve water passage down stream may be plugged and in need of cleaning.
