Maintenance and Troubleshooting
Important Notes:
•
Disconnect power before any repair or maintenance is done on the display.
•
Qualified service personnel must make any access to internal display electronics.
•
Disconnect power when the display is not in use.
6.1 Component Location and Access
All internal electronic components and digits can be reached by opening the hinged access
doors on the front of the display. Figure 15 demonstrates the internal display component
layouts. Component placement varies slightly with each Fuelight
™
model.
Visual Structural Inspection
At least once a year, check the display to ensure the structure and components are in good
condition. Inspect the paint and cabinet for corrosion. Make sure fasteners are tight. Tighten
or replace as required.
Note: Disconnect power before servicing the display. Also disconnect power when the
display is not in use. Prolonged power-on may shorten the life of some electronic
components.
