LI-COR 6400-18 Installation And Operational Instructions

6400-18
RGB Light Source
Installation and Operational Instructions
The 6400-18 RGB Light Source is designed to be used with the 6400-17 Whole Plant Arabidopsis
(WPA) Chamber, the 6400-24 Bryophyte Chamber, or with the LI-6400XT and any clear-topped
chamber. The LED calibration is retained in the light source, making it possible to switch from
instrument to instrument without the need to enter calibration constants. The red, green and blue
LEDs can be independently adjusted to allow users to select any desired color combination.
Photosynthetic response differs with illumination wavelength, and is explained in more detail in
Application Note 5.
The assembly requires a Phillips head screwdriver, and takes about 15 minutes to complete.

Follow these steps to install the 6400-18:
1. Install the 6400-17 or 6400-24 Chamber as per the instructions included with the chamber.
2. Remove the 4 Phillips head screws on the bottom of the RGB Light Source. Make sure that
there is a Propafilm covering over the aperture on top of the chamber top plate. With the
Propafilm facing the bottom of the RGB Light Source, attach the chamber top plate to the
bottom of the light source using the 4 Phillips head screws (Figure 1).
3. Connect one end of the gray control cable to the Control connector on the side of the light
source, and the other end to the 37-pin Auxiliary connector on the LI-6400/LI-6400XT console
(Figure 2).
4. Connect one end of the power supply cable to the light source. Connect the power supply to
mains power (Figure 2). When first plugged in, the RGB light source cooling fan may run
momentarily; this is normal. The power supply will automatically adjust for varying voltage
inputs (100-240VAC, 1.4A max., 50-60 Hz). The power supply can be attached to the LI-6400/
LI-6400XT console using the supplied Velcro kit, if desired (Figure 3).

the RGB Light Source using 4 Phillips head screws.
