Possible Cause and Remedy
n/a
No power
Luminaire does not power
up
Circuit not energized...
- verify circuit breaker is turned on.
Not plugged in...
- ensure A/C cable is connected to power source.
Power cable wired incorrectly...
- verify power cable and connector are wired
correctly.
n/a
DMX Data Input

- check for DMX terminator.
n/a
Single LED not operat-
ing
One LED (out of the
seven) is not producing
light or responding to con-
trol.
LED Driver PCB not Powered...
- Check Power to the driver board for that LED.
The driver board has 2 green LEDs on it. Each
LED signifies a different power supply. The outer
green LED (closest to the edge of the board)
signifies that the driver board is getting power
from the 12V supplies in the base (through the
blue wire). The inner green LED signifies that it
is g5V power from the round motherboard
(through the header/pin connector)
LED Driver PCB not Properly Connected...
- Check communication to the driver board for that
LED. The Driver PCB has 2 red LEDs on it. If the
LEDs are:
State 1
: Always on, but alternating brightness
- board is communicating properly
State 2
: Alternating on and off very quickly -
board is downloading software from Main
Control Board. This state should be replaced
by State 1 after programming.
- Check Motherboard for short to ground
