NOTE:
The maximum loading claimed in the table is at ambient temperature 25°C (77°F).
For linear long runs, center connection to the LED strip is recommended to minimize voltage drop.
Tips
• For optimal light uniformity in halo-lit applications the Tetra
®
LED modules should be mounted on UL recognized plastic and the
light output from the Tetra
®
LED system should be directed back into the sign enclosure. This will allow for uniform backlighting of
the sign and will provide simple mounting for the Tetra
®
LED system.
• A best practice for the supply wire at the point at which it is brought into the sign is to have a drip loop on the inside of the letter to
keep water from collecting on the Tetra
®
LED strip.
• These products are not required to be enclosed or protected from weather.
Troubleshooting
Symptom
Solution
All letters are OFF
•
Check AC input connection and/or check circuit breaker.
•
Check wire connection(s) at the Tetra
®
LED System and power supply for improper termination(s) or short
circuits. Properly terminate or replace the wire connection(s).
•
Check that connections are the red striped wire (+) of the LED strip to the red wire (+) of the power supply and
the white wire (-) of the LED strip to the black or blue wire (-) of the power supply.
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.
•
Ensure the overall length of the Tetra® LED System does not exceed the maximum load.
Some of the letters are
not illuminated
•
Check wire connection(s) at the Tetra
®
LED System and power supply for improper termination(s) or short
circuits. Properly terminate or replace the wire connection(s).
•
Check that connections are the red striped wire (+) of the LED strip to the red wire (+) of the power supply
and the white wire (-) of the LED strip to the black or blue wire (-) of the power supply.
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 on the face of the letter.
