Troubleshooting a two-wire decoder control system is easy – once you know what to look for in the wire path. The process is not intuitive, and that is where this training class can help. We will cover the operation of the two-wire path and the steps required to identify the three main causes of failure on the wire path, and open, a short, and a ground fault.
Unit 1 Decoder system wire path components
Unit 2 Decoder functionality
Unit 3 Troubleshooting an open circuit
Unit 4 Troubleshooting a short circuit
Unit 5 Troubleshooting a ground fault
Upon completion of this course, students will be able to:
1. Explain the functionality of a decoder
2. Troubleshoot and locate an open circuit on a two-wire path
3. Troubleshoot and locate a short circuit on a two-wire path
4. Troubleshoot and locate a ground fault on a two-wire path
