We are constantly endeavoring to improve our instruments and to adapt them to the
requirements of modem research techniques and testing methods. This involves modification
to the mechanical structure and optical design of our instruments.
Therefore, all descriptions and illustrations in this instruction manual, including all
specifications are subject to change without notice.
To ensure proper use, please read this manual carefully before using the MLC-150 cold light
source.

To meet the demands of both international and domestic markets, Motic has developed the new
MLC- l50C cold light source. Besides a switching power supply that ensures a regulated voltage
for the lifetime of the halogen bulb, many other safety precautions have been taken to provide a
safe and reliable cold light source. In addition, an infrared filter and filter assembly have been
incorporated to minimize halogen light heat output in order to achieve cold light illumination and
meet the objectives of many kinds of color temperature light rays.
The MLC-150C can be applied extensively in various fields that require bright light illumination
including' microscopy, medicine, education, and many other areas of scientific research. With a
sturdy construction, practical and aesthetic design, minimal working noise and user friendly
controls' it is a welcome addition to any laboratory. A large selection of additional fiber liehts are
also available to choose from.

3. Usage
1. Confirrn your local power supply rating and then at the back of the unit adjust the voltage
conversion switch accordingly (115V or 230V).

2. Users are able to choose the tight intensity control method as required. Shorl-range control
method: Switch the 'Light control mode switch'to 'LOCAL' (see diagram 1). Place the unit
on your desk and use the light intensity adjustment knob on the front panel of the unit to
adjust the light intensity. Remote control method: Switch the 'Light control mode switch' to
'REMOTE' (see diagram 1). Place the unit anywhere within 1.5 meters (as the cable allows)
of your person, plug the remote control cable into the main unit using the DB9 plug and begin
to adjust light intensity using the remote control.

Diagram 3
Plug the power cable into the AC input socket on the back panel of the unit (see diagram 1).
From the front panel, turn the power on, at which point the LED indicator light will illuminate
indicating the power has been connected and the cold light source has begun working. Adjust
the light intensity dial making sure the outpllt light changes from bright to dark or vice versa.
Install the light-output end of the fiber optic light in the appropriate location on your
microscope or any other location that requires cold light illumination and begin use.
Once the cold light source has been properly assembled and tested it can be placed alongside
(effective within a 1.5 meter range) and used with your microscope or any other device
requiring cold light. Be sure the front panel of the control box is free from obstruction as this
will ensure the user is able to conveniently adjust the light intensity and/or switch fiber lights
as necessary. (see diagram 4 for suggested setup)

4,, Installing the :filter
Users may install filters as required. To install a filter: Loosen the holding screws on the lamp
housing and remove the lamp housing from the main unit. Find the filter installation location (at
the front of the housing, against the fiber optic light socket) and insert the filter (making sure it is
facing the right direction) as shown in diagram 5 below. Generally, a glass filter unit has been
installed at the point of manufacture. If it is required that the glass filter slice be changed, please
note that it must be installed facing the proper direction. The side of the glass with the coated film
must be installed facing the incoming light ray or the glass slice will become damaged.

5. Ghanging the Bulb
If the bulb is used passed its specified lifetime, it may lead to damage and should thus be changed.
To change the bulb: pull out the power cable plug, make sure the lamp housing has cooled
sufficiently, loosen the lamp housing screws and remove the lamp housing from the unit. Next,
push down the steel wire holding the bulb in place, and gently remove the bulb. Replace with a
bulb of the same specifications (21Vl150W), insert the lamp housing back into the main unit and
tighten the holding screws (see diagrams 6 and 7 below).

6, Golor temperatu:re display
An LED indicator is employed to display the current light output color temperature value. When
the light intensity dial is adjusted, the output light intensity and color temperature value will
change in accordance. The value displayed on the LED indicator (the light moves from left to right
with intensity) represents the current light output color temperature value when no filter has been
installed. If a standard filter has already been installed, a value of 500 must be added to the value
displayed on the LED. For example, if the LED is displaying its maximum value of 3200K, add
500 to this value to calculate the real color temperature (3700K). If a different color filter is being
used, the color temperature displayed by a color temperature measurement instrument should be
taken as standard.

7. Maintenance and Care
Use the instrument in an area with good air circulation. Do not place large devices or devices
that emit large amounts of heat near the instrument. When the instrument is in use, make sure
the air intakes at the base and sides and the fan at the back of the unit are kept free from
obstructions as this will ensure proper heat dispersal. As well, do not cover the outer surface of
the instrument with paper, cloth or any other object that will affect heat dispersal.
If the instrument has been used for a period time and suddenly does not illuminate, it is
possible the bulb has reached the end of its life. A new bulb of the same specifications should
be installed. When in use, the instrument should not be frequently turned on and off as this will
shorten the life of the bulb and damage the electronics.
When installing and using the internally housed halogen bulb and filter, protect from oil stains
by avoiding contact with bare hands. If contaminated, use absorbent cotton dipped slightly in
an ethyl-alcohol mixture to wipe clean.
4. Do not position the equipment so that it is difficult to unplug the power supply cord from the
unit.
1.
The instrument should be kept clean and free of dust, moisture and oil to ensure the machine's
proper electrical insulation. When cleaning the outer surface of the instrument, do not use
water or any corrosive cleaning agents. Use a clean piece of silk cloth dipped slightly in
benzene to wipe clean. If the instrument is not to be used for an extended period of time, place
it back into its box and store in a low humidity environment.
When using the fiber optic light, do bend at a right-angle or even slightly less than a
right-angle as this will cause the optic fiber to break. The light's input/output plugs and the
flexible tube's joints are especially susceptible to breakage.
Before using this instrument, ensure the local power supply voltage rating is the same as at
least one of the voltage conversion switch settings on the back panel of the unit. As well, be
sure not to randomly switch the voltage setting at any time as this may damage the instrument.
Users should respect local safety protocol and must bear full responsibility for the safe
operation of this instrument. Should the instrument become damaged, do not attempt to
disassemble and/or repair. Contact the distributor's service department or send the instrument
directly to the manufacturer for repairs.
