Chapter 9 Troubleshoot the System
Isolate the Problem
This section provides general troubleshooting information to assist
you when trying to isolate problems.
Check for Adequate Power
A terminal that does not receive adequate power could result in
unpredictable behavior. Verify the power requirements in Appendix A
of this manual.
Check Indicators at Startup
After a successful startup, both LED indicators on the terminal are off
and controlled by the application running on the terminal.
When the terminal starts, the fault (red) indicator should be off except
for a few brief flashes, and the comm (green) indicator on.
• If the indicators on the 700 to 1500 terminals remain off, the
power supply or logic module has failed. Check the power
cable. If the power is not within range, replace the power
supply. If the power is within range, replace the logic module.
• If the indicators on the 400 and 600 terminals remain off, check
the power cable.
