Changing the LED modules in the Colibri 3 illumination system
How to change an LED module, i.e. the LED module for LED slot 1 (Fig. 3-38/
):
•
Remove the Colibri 3 from the stand: Follow the instructions of section 3.1.22.1 in reverse order.
•
Loosen the four captive clamping screws (Fig. 3-38/

) on the front side with an Allen wrench (AF3).
•
Remove the back cover (Fig. 3-38/
7
).
•
Disconnect the LED module power cable connector (Fig. 3-38/
1.1
) from the PCBA (Fig. 3-38/
1.6
).
•
Loosen the knurled knob (Fig. 3-38/
1.3
) by hand and remove the old LED module (Fig. 3-38/
1.4
).
•
Select the right LED module with matched LED-specific labels (Fig. 3-38/
1.2
and
1.5
) and insert it in
the correct slot (Fig. 3-38/
).
NOTE
One label on the LED slot (Fig. 3-38/
1.5
) indicates the wavelength range for this position; the
other label on the LED module housing (Fig. 3-38/
1.2
) indicates the wavelength of the LED
module. See the table below as well.
•
Tighten the knurled knob (Fig. 3-38/
1.3

•
Push the LED module power cable connector (Fig. 3-38/
1.1
) back to the PCBA (Fig. 3-38/
1.6
).
•
If required, replace the LED modules of LED slots 2, 3 and 4 (Fig. 3-38/
,
and

way.
•
Mount the back cover (Fig. 3-38/
7
) and fasten the four anti-loss clamping screws (Fig. 3-38/
