TROUBLESHOOTING QUICK GUIDE
Problem
Likely Cause
Solution
XFL product does not light up.
Incorrect, inadequate or malfunctioning
power supply.
Make sure power supply is turned on and receiving power.
Use a multimeter to test and ensure that XFL product is
receiving 24V DC power.
Incorrect wiring.
Confirm correct polarity (+ to + and - to -) when joining
tape lights as well as when connecting to the 24V DC
power supply. Check at every connection point to ensure
polarity is not reversed.
Only part of XFL product is lit.
OR
XFL product blinks on and off.
Incorrect wiring or insecure connections.
Power supply is inadequate for the
selected length of XFL product.
Check connections on unlit portion of XFL product.
Ensure terminal screws or metal prongs of splice
connectors are pierced through or contacting solder pads.
Install a higher wattage power supply or reduce wattage
by shortening length of XFL product being used.
Overheated power supply. An
overheated power supply will trip the
internal auto-reset of the power supply
repeatedly, turning the system on / off.
Reduce power supply load by shortening the lengths
XFL product being used. Consider relocating power
supply to a cooler location with increased air flow.
Inconsistent brightness along
XFL product
Voltage drop from wires running between
the power supply and XFL product.
Decrease the length of the 24V DC power feed wires or
use thicker gauge wires between the 24V DC power supply
and the XFL product.
Use shorter lengths of XFL product.
XFL product overheats
Ambient temperature is above
recommended rating.
Ensure installation environment is rated for XFL product.
Voltage input is higher than
recommended voltage.
XFL product exceeds maximum
recommended run length.
Confirm that power supply output is 24V DC.
