Equalizer Light Feedback:
Although LED’s do not vary in light intensity over time as drastically as other lighting
technologies, the LED light engine will slowly degrade as it ages.
The LLS 3 has a built in photo sensor that monitors the light output and can be used to
maintain a constant light output during the use of the LED. See the RS-232
programming section on how to activate and use the equalizer.
Once activated, the LLS 3 will maintain a constant light output for a given setting for any
of the 4 control modes. The equalizer will automatically obtain new set-points whenever
a new RS-232 or Ethernet intensity is set. If the intensity needs to be changed by the
analog or front intensity knob modes, then the equalizer should be turned off, the
intensity adjusted, then turned on again.
Note that this feature is not intended to be used for startup conditions. LED light output
will drift considerably in the first few minutes of turn on. The use of this feature is to
maintain stabilized light over long periods of time.
Resetting to Factory Defaults:
There are two means of resetting the factory defaults:
• Utilize the factory reset command via RS-232 or Ethernet
• Press and hold the On/Standby button for 10 seconds while power is applied
