Routine/Preventative Maintenance
The service intervals listed in this section are recommendations. These service intervals
can be adjusted if necessary due to special considerations. Contact Daktronics
Customer Service for recommendations based upon specific conditions.
Sign Cabinet Inspection
At least once every year:
• Check for evidence of water intrusion in the sign, (i.e., water stain marks).
• Check for any leaks that may have developed. Seal them with a silicone sealant or
another suitable sealer.
• Inspect all module gaskets for tears, missing pieces, etc. Replace as necessary.
• Check the drain holes in the bottom of the cabinet to ensure they are unobstructed.
Sign Controller
At least once every year:
• Ensure all connectors are secure and the cables are not damaged in any way.
• Check the operation of the sign controller.
Structural Inspection
At least once every year:
• Inspect the mounting structure thoroughly for signs of corrosion, loose bolts, and
overall stability.
• Check the connections of the earth-ground wires, if accessible.
Photo Sensor Assembly Inspection
At least once every year:
•
Inspect the light sensor assembly for foreign material that could obstruct airflow
around the photo sensors.
• Clear away any foreign material.
LED Cleaning
If needed, clean the LEDs with a damp cloth or a soft brush. Do not spray cleaner directly
onto the LEDs. The frequency the LEDs need cleaning depends on site conditions.
Ventilation System Inspection
At least once every year check that all the fans run.
To do this, note the setting on the cooling thermostat and then turn it clockwise until the
fans turn on. Make sure all fans are running. Press the black button to test the thermostat.
After opening the intake fan assembly, check the fan blades for dirt and debris. If the fan
blades have a large accumulation of dirt and debris, change the filters more often. Keep
the fan blades clean to maintain fan efficiency and ensure proper cooling. Next, spin
the fan blades with a pen or pencil to ensure the bearings are free and the fan is still in
balance.
Check and clean filter as necessary.
