Diagnostics and Troubleshooting
7.3 Temperature Sensor Diagnostic
If the display includes a temperature sensor, the temperature sensor
board will also provide diagnostic information. The temperature
sensor board is located inside the temperature sensor housing which
is located near the display. Refer to Figure 3. The sensor board
diagram in Figure 29 shows the red diagnostic LED (DS2) near the
bottom edge of the component. This LED will flash at variable rates
when transmitting temperature information and provides evidence
that the unit has power.
Refer to Appendix B: for temperature sensor mounting and
connections.
7.4 Troubleshooting Display Problems
This section contains general
