Entire sign or leg does not light
after complete installation.
Check connection from power supply lead to first module. Make sure polarity of connections
made at the power supply lead and any jumper wire is correct. Power supply outputs should
be connected red-to-red and white-to-white.
Check output voltage of power supply using a voltmeter. The output voltage should be
12.0VDC ± 0.5VDC. If there is no output voltage, have a licensed electrician check input
voltage. Make sure power supply is connected correctly and getting primary power. Probably
AC input wire is connected to ground terminal of power supply. If power supply is connected
properly and getting primary power and there is still no output voltage, try a different power
supply.
Still does not light.
If power supply is getting primary power and the modules do not light, there may be a short
in the secondary wiring. Check all connections and cap all loose wires.
Still does not light.
The primary cause of a portion of a S-LED leg not lighting or lighting intermittently is a bad
connection or reverse polarity connection between the modules that light and the modules
that don’t light. Check this connection.
Beginning of a leg lights, but the
entire leg does not light or lights
intermittently.
S-LED is designed so if one module fails, it will not cause the entire sign or leg to go out. If one
module does not light, but all others in the leg do, replace this module with a new one.
One module does not light, but
all others in the leg light.
Check each run has no more than maximum number of modules. Also ensure that type of the
extension wire from SMPS to the first module is correct. If wires are not thick enough to
transmit current from SMPS, this will cause voltage drop and will dim the modules at the end.
All modules light, but some of
them are dimmed.
Channel depth is too low, or center distance between modules is too far. Refer to 'LAYOUT
DENSITY GUIDELINES' for more information.
Dark spots or dimmed spots
occur.
Covering acrylic is not intended for LED illumination. Use light diffusing acrylic sheets which
are specially made for LED light source.
Still has spots.
