Problem Cause Remedy
Transmitted-light illuminator of
Primo Star iLED cannot be
switched on. Transmitted light / reflected light
changeover switch is in reflected light
(
Fluorescence ) position.
Turn transmitted light / reflected light
changeover switch to transmitted light
(
Brightfield ) position.

Reflected-light illuminator of
Primo Star iLED cannot be
switched on.
Reflected-light illuminator not exactly
enough aligned to microscope stand
or displaced, causing interruption of
power supply by interlock function. Align reflected-light illuminator exactly
to microscope stand and tighten
clamping screw sufficiently.
4.3 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.
