Indication of maximum light
intensity
Intended use:
The cold light source KL 2500 LCD
is intended for industrial and laboratory
applications.
Cold light sources are used for the
intensive illumination of all types of
objects. The infrared components in
the lamp radiation are filtered out.
High intensity visible light is guided to
the object through flexible or self-
supporting, movable light guides. The
unit is tested and certificated to the
applicable standards on electrical labo-
ratory equipment (DIN EN 61010-1 and
UL 3101-1). The 230 V version also
conforms to the standard on medical
electrical equipment (DIN EN 60601-1).
Safety information:
Please read and obey these instruc-
tions carefully. The instrument's
safety cannot be guaranteed if they
are not obeyed.
Avoid looking directly into the open
clamping sleeve or the light guide exit
when the light source is switched on.

The KL 2500 LCD emits high-intensity
visible light. Because light-absorbing
materials have the physical property
of converting incident light into heat,
damage can occur to heat-sensitive or
flammable light-absorbing materials. To
avoid such thermal damage and
the potential danger of fire or burns,
please obey the following instructions:
Never cover up the open clamping
sleeve or the light guide exit
(danger of fire).
Never cover up the open clamping
sleeve or the light guide exit with
your hand or other part of the body
(danger of burns).
When illuminating heat-sensitive or
flammable light-absorbing objects
(e.g. in microscopy), special care
must be taken to ensure that a suit-
able light guide separation distance
and lamp brightness are chosen so
that no thermal damage occurs.
When the light source is switched
on, all light guide exits not being
used in the working procedure must
always be at a safe distance – at least
10 cm – from heat-sensitive or
flammable light-absorbing materials
(prevention of possible danger of
fire). Therefore take care that each
light guide exit is at the above safe
distance from, for example, dark/
colored textiles and dark/colored
wood or plastics surfaces.
To avoid unnecessary stressing of
biological tissue by illumination with
visible light, reduce the brightness
and duration of illumination
to the absolute minimum required
level.
It is absolutely essential that you
ensure that:
your KL 2500 LCD light source is
operated at the voltage stated on
the model plate (17);
all ventilation openings (13, 14, 15)
are kept free. In the event of insuffi-
cient cooling, a built-in thermostatic
switch switches the instrument off
temporarily (see point 5 "Trouble-
shooting");
the lamp has cooled down before
it is changed; to remind you, a
warning symbol is attached to
the lamp compartment door:
(warning of hot surface);
the filter wheel has cooled down
before being removed. It carries
the warning symbol;
the light source is operated exclu-
sively with the filter wheel inserted.
The filter wheel must always be in
one of the five locking positions.
The light source has been developed
for operation in dry rooms only
(see point 7 "Technical Data").
This instrument is not suitable for
operation in areas where there is
an explosion hazard.
Safe disconnection from the power
supply takes place also by pulling
out the mains plug.
The instrument must not be opened
or dismantled. Technical modifica-
tions to the instrument are
forbidden. Repairs must be carried
out only by the manufacturer or
by its authorised customer
service agencies.
Please ensure that every user of the
instrument has quick access to these
instructions.
The manufacturer is not liable for
damage caused by failure to obey
these instructions.
