A hardware alert occurs when the controller is not detecting all of the user-defined Max Active Stations. Irrigation will not occur on those stations, because the controller cannot irrigate stations that are not detected.

Possible causes

• The user-defined Max Active Stations exceeds the number of stations detected by the controller
  
  
• One or more Station Keys are missing or improperly installed
  
  
• The ribbon cable between station input/output boards is defective or connecting pins are bent
  
  
• A station output board has been damaged

To View a Hardware Alert

1.  Press ALERTS.

2.  Press à until the VIEW HARDWARE STATUS screen displays.

3.  Press SELECT to view the alert.

Possible Fixes

• Verify Max Active Stations in SETUP menu
  
  
• Confirm ribbon cables are seated properly
  
  
• Verify the number of Station Keys is adequate for the required stations
  
  
• Use another ribbon cable or unbend the connector pins
  
  
• Look for scorch marks on the board or a strong odor of burnt components. Replace as needed.

How to Clear a Hardware Alert

Approximately 30 seconds after the situation is remedied, the controller automatically clears this alert.
