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 24V.
»
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
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the interference at his own expense.
This Class [A] RFLD complies with the Canadian standard ICES-005. Ce DEFR de la classe [A] est conforme à la NMB-005 du Canada.
