Symptom
Solution
All letters are OFF
• Recycle AC power, turn it off, then turn on again.
• If still off, check the power supply DC output voltage using a voltmeter. It should be nominally 12V.
»
If there is DC output, inspect and correct all DC wire damage/polarity issues; If no issue is found, replace the
OFF-module string.
»
If there is no DC output, have a licensed electrician check the input AC voltage and if there is correct AC voltage,
replace the power supply.
»
If there is no AC voltage, correct the upstream AC issue.
Some LEDs appear dim
• Ensure the overall length of the Tetra
®
LED System does not exceed the maximum load.
• Ensure the length of supply wire is equal to or below the recommended remote mounting distance.
Some of the letters
are not illuminated
• Inspect and correct the wires of the non-illuminated letters for damage/polarity issues; If no issues are found, see the
troubleshooting solution for “All letters are OFF.”
Shadows
• Re-route supply wire and secure to the back of the can with electrical grade RTV silicone. Adjust wire connector
orientation so that it does not cover any LEDs.
• Adjust LED layout to ensure uniformity of illumination of the face of the letter.
Troubleshooting
