Termination Connector" on page 13.
Luminaire has detected an over temperature
condition...
- The luminaire will reduce power to all 7 LEDs if it
senses that one LED is operating over the
specified temperature. LED temperature is read
and recorded through a thermistor imbedded in
each LED chip. The two yellow wires carry the
information (on temperature) to the LED's
respective driver PCB.
- Check the thermistor temperatures of each LED
through the fixture's LCD display.
If one LED is much hotter than the others...
- Check to see that the LED's fan is running /
connected to the Driver PCB.
