1.0 Introduction With your purchase of the EUROMEX cold light source LE.5210 you have chosen a quality product. The LE.5210 cold light source is developed for use in education, laboratories and industry. The LE.5210 is extremely usefull for photo-micrography The maintenance requirement is limited when using the LE.5210 in a decent manner. This manual describes the construction of the cold light source, how to use the cold light source and maintenance of the cold light source.

5.0 Preparing the cold light source LE.5210 for use Place a light conductor in the connector (D) so that the flat side is pointing upwards in the direction of the set screw (C). The light conductor always has to be placed completely into the inlet. Now tighten the set screw to secure the light conductor. At this stage the EUROMEX LE.5210 is ready to be used. Connect the power cable to the mains supply and switch on the LE.5210 by turning the knob (E) clockwise. The lamp will light up and the fan starts running. By turning the light adjustment knob (E) with scale from 1 - 10 clockwise, one can increase the light intensity, this results in an increase of the colour temperature of the outcoming light (maximum 3200° K). Please note that use in position 9 is recommended rather than position 10, for in such case the life of the bulb is extremely longer.
When using the LE.5210 for photomicrography position 10 is recommended, for in position 10 the colour temperature is 3200° K. For a good balance in colour, one should use a daylight film together with conversion filters LE.5231, mounted in focusing heads LE.5222 and aspherical condensorlenses LE.5224. Now turn the potentiometer knob at position 0. When the EK-1 is to be transported immediately, leave it at position 1 for a minute. The bulb will be cooled.
4 6.0 Using the light conductors The self-sustaining and flexible light conductors are equipped with glass-fibres for maximum conductivity of light, and should be treated as follows: Carefully point the conductor towards the object and only bend the conductor in one direction. The bending radius "R" of the light conductor should never be lower as 50 mm. because otherwise the metal construction of the light conductor can be damaged. This can cause instability and inflexibility.
7.0 Maintenance and cleaning After use the instrument should be cooled down. The instrument can be easily cleaned with a soft cloth.
7.1 Exchanging the halogen bulb Always pull the plug from the mains socket first and let the instrument cool down for a few minutes.
Warning:
Remove the 4 Phillips screws (F) on both sides of the LE.5210 and take of the cover. Take the reflector and fitting out of the holder vertically. Remove the bulb out of the fitting and replace it with a fresh one. Put the reflector back into the holder in the right way.
