Troubleshooting, Cont.
E. Controller Indicates Valve Opening Failure
• Verify that the 3-Way Selector is in the “Auto” position. If it is not, turn the switch to the
“Auto” position and then check to see if the controller indicates that the valve is open.
• Verify that the controller and your software are functioning properly. If not, restart the
controller and make certain that your software is properly configured.
• Verify if there is water flow downstream from the hydrometer. If there is not, this indicates
that the valve is indeed closed.
• Check the electrical connections as described on page 8.
• Check the register as described in the first step on page 5.
• Remove the 3-Way Selector. Clean or replace as necessary.
• Verify solenoid operation. Repair or replace as necessary.
• Disassemble the hydrometer as described in the Maintenance section, pages 23-38.
• Clean or replace the strainer (1½” and 2” models only).
• Inspect the diaphragm and o-rings. Replace as necessary.
F. Controller Indicates Valve Closure Failure
• Verify that the 3-Way Selector is in the “Auto” position. If it is not, turn the switch to the
“Auto” position and then check to see if the controller indicates that the valve is open.
• Verify that the controller and your software are functioning properly. If not, restart the
controller and make certain that your software is properly configured.
• Move the 3-Way Selector to the “Close” position. Check to see if the controller indicates
that the valve is closed. If so, this indicates that the solenoid is not functioning properly.
Repair or replace as necessary.
• Verify if there is water flow downstream from the hydrometer. If there is, this indicates that
the valve is indeed open.
• Check the electrical connections as described on page 7.
• Check the register as described in the first step on page 4.
• Remove the 3-Way Selector. Clean or replace as necessary.
• Remove and clean the finger strainer. Replace if necessary.
• Disassemble the hydrometer as described in the Maintenance section, pages 22-37.
• Inspect the diaphragm, valve cover and o-rings. Replace as necessary.
G. Leakage from Valves or Connectors
• Inspect the control hoses, connectors, shuttle valves and adapters. Tighten and replace as
necessary.
H. Constant Drainage from Pilot Valve
• Repair or replace the pilot valve.
