Changing the LED module in the reflected-light fluorescence illuminator

ATTENTION
The LED module in the reflected-light fluorescence illuminator has to be changed in any case
by an authorized service technician.
The Primo Star iLED microscope with reflected-light fluorescence illuminator is provided with
an interlock function to switch off the installed LED of the reflected-light illuminator as soon as
the reflected-light illuminator will be turned with regard to the stand or detached or if the lid
of the reflected-light illuminator will be removed.
• Disconnect the reflected-light illuminator from
the power supply.
• Detach the tube (see also section 3.5.1). To this
end, loosen the knurled screw, turn the tube
counterclockwise by approximately 90° and lift
it out of the dovetail mount.
• Loosen the three fastening screws (Fig. 33/1) of
the lid of the reflected-light illuminator (2.5 mm
Allan key).
• Disconnect the plug-in connector of the LED
module connection cable (Fig. 34/3) on the
circuit board. To this end, press the safety hook
against the connector to release it and pull out
the connector.
• Unscrew the two fastening screws of the LED
holder (Fig. 34/1) completely. Remove holder
(Fig. 34/2) and screws.
• Remove the LED module (Fig. 34/4).
• Insert the new LED module. Because of limited
space, the flat side of the LED module must
point to the circuit board.
