Info, impact, causes, and troubleshooting a "Device Valve Decoder Open Circuit" message.

Common Causes

• A failure solenoid or a bad splice of the solenoid.
• Broken wire or there.
• A solenoid attached to the biCoder.

What Happens Now?

• Open circuit on zone 9, which the zone cannot operate.
• Irrigation for zone 9 will not happen.
• The biCoder serial number: E188171.
• Before troubleshooting the message.
  • This ONLY applies to the solenoid side of the biCoder, doesn’t apply to the 2-wire path

Troubleshooting

• Replace solenoid or DBR/Y-6 splices
• If broken zone wire.
  • Use traditional wire repair tools to isolate the short.
• If you have un-used biCoder outputs that would normally go to a solenoid, unassign them
• Controller will check output of wires for biCoders.
  • Conventional wire systems, will check the terminals of a powered biCoder
• Can't find a wire or solenoid?
  • It will create and open circuit message.
• To avoid the messages, go to BaseManager → Device → Assign biCoders.
  • This will help you unassign the unused serial numbers.
