The controller identified high voltage on the indicated zone.

Scrolling Fault Message
ZONE XX SHORT
OUTPUT SHORT CIRCUIT
The problem may be the result of a defective valve solenoid or a field wiring issue.
As a result...
The zone indicated will be skipped during watering cycles until the problem is fixed. The fault indication can be manually cleared or will be automatically cleared if the short condition goes away and the output turns on successfully.
What to do?
Check the solenoid(s) and wiring. To identify the offending solenoid valve in the field, remove the wiring from that solenoid. Now, run an Outputs Test using your SmartLine Controller.
- If the test presents a zone valve circuit is SHORT (no power), field wiring is likely the issue.
- If the test presents a zone valve circuit is OPEN, the solenoid is likely the issue.
Running an Outputs Test
Your SmartLine® controller can assist you with several diagnostic functions by pressing NEXT when TESTS appears.
- Turn the dial to Advanced Menu. Push NEXT button to access review functions. Use the UP/DOWN buttons to select review functions you wish to view.
- Press NEXT when TESTS appears. Use UP to select OUTPUTS function.
- Use the NEXT and BACK buttons to scroll through Master Valve and Zone Valves to view AC Amp reading for each valve.
- The typical range is 150 to 350 mA per valve with a valve connected. An OPEN or SHORT message will indicate a problem with the zone.
Note: If you have more than one valve on a zone, the SmartLine® controller will measure total current for the combined valves.
During an installation, which involves field wiring, be sure to carefully separate all conductors so not to damage any wire insulation.
Be aware that an electrical “short” (or contact) between the valve wires and another source of power can damage the controller and has the potential to create a fire hazard.
