A slow responding controller, erratic station behavior, or an active short circuit/overcurrent alarm can indicate a 2-Wire issue. The first step in troubleshooting a 2-Wire issue is to isolate the problem between the controller and the 2-Wire path.
Note: You will need a small flathead screwdriver & access to the controller for this step
- Disconnect the 2-Wire path at the controller terminals (Line 1A/1B, 2A/2B)
- Observe what happens to the Line Lights/Operation
- If the controller returns to normal operation, your problem is in field (2-Wire path).
- If the controller does not return to normal operation, you may have a compromised controller. Contact Tucor support at (724) 935-6850.
- If the issue has been isolated as a problem in the field, reconnect the 2-Wire path and proceed with Step 2.
