Summary

In the event of an isolated No Connect (2-wire decoder communication failure), where a single device alert is present over a large section of 2-wire, read what's below for added information and resolution steps. 

Problematic Splices

The splices on the decoder could be corroded, the result of water intrusion due to improper splice hardware or otherwise. The correct splice hardware is the 3M DBR/Y-6 connector, in the provided waterproof capsule. This is the only splice hardware that meets specifications, and is included with every decoder set. They CANNOT be reused, so ensure to bring a new set if you need to replace the splice.

Malfunctioning Decoder

The decoder may be faulty, which can be seen by looking for the LEDs on the top of the decoder. If none are present when the decoder is in operation or when running a test of that device from the controller, or the WeatherTRAK mobile application, take the decoder to the controller. Plug it directly into the controller without the 2-wire path, and verify if the decoder is the issue via test from the controller menu.

Required Tools

#2 Phillips screwdriver

Wire stripper

2 NEW 3M DBR/Y-6 connectors

Process Steps

Check the Alert

Check that the alert is for a specific 2-wire device.

• @Jonathan to fill out the steps for 7x and 8x to check the alert.

Check the Controller

• @Jonathan to fill out the steps to verify the controller in a 2-wire no connect process.

Check the Decoder

• @Jonathan to verify these steps and update as needed.

1. Pull 2-wire device from the wire path and valve box and bring to controller.
2. Disconnect all other 2-wire from controller, connect 2-wire device and perform a device test from the controller menu.
   1. If test returns a communication failure, 2-wire device must be replaced. 
   2. If test returns on okay status (Or open circuit solenoid if testing a valve decoder with no connected solenoid), re-splice 2-wire device into original field location. Before re-splicing, confirm you are using new DBR/Y-6 connectors. While re-splicing, ensure the wires are not loose in the wire nut, the wire nut is pushed to the rounded base of the grease cap. Before closing the valve box, ensure that the rounded base of the grease caps are pointing up. See WeatherTRAK Install Valve Decoders onto the 2-Wire Path on page 25 of WeatherTRAK 2-Wire Installation Guide.
