Troubleshooting Manually
If you do not have a millamp clamp meter, you can manually break the two-wire connections in a
systematic manner to isolate a wire segment or device that is generating the Over Current
message.
1. Determine the approximate halfway point of the two-wire path, and then break the
connection at that valve box.
2. Check the controller again. Perform one of the following actions:
 If the Over Current message persists, the problem is in the half of the two-wire that is
still connected to the controller. Find the halfway point of that segment and start at step
1 again.
 If the Over Current message goes away, the problem is in the disconnected half of the
two-wire path. Reconnect the two-wire path, and then disconnect at the halfway point
of the problem section. Start at step 1 again.
3. When you have isolated the device or the stretch of two-wire where the problem seems to be
originating, remove the two-wire path and connect the device directly to the controller. If the
Over Current message returns, the device is faulty and will need to be replaced.
Troubleshooting: Lost Devices | No Response
Begin by walking the two-wire and checking for what has changed that may have caused the
communication errors.
• Is there just one communication error or is there a group of them?
 If there is more than one, are they all on the same wire? The same physical area?
 If this is the case, check the connections and wiring in that area of the two-wire.
• Repeat as necessary
