1 Important information Symbols used: Warning of danger (caution, obey documentation) Warning of a hot surface Instrument of Protection Class II Off (disconnected from mains) On (connected to mains) 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 selfsupporting, movable light guides. The unit is tested and certificated to the applicable standards on electrical laboratory equipment (DIN EN 61010-1 and UL 3101-1) and to the standard on medical electrical equipment (EN 60601-1 and UL 2601-1).

➧ 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 suitable light guide separation distance and lamp brightness are chosen so that no thermal damage occurs.

➧ the lamp has cooled down before it is changed; to remind you, a warning symbol is attached to the lamp compartment door:

➧ the filter wheel has cooled down before being removed. It carries the warning symbol;

➧ the light source is operated exclusively with the filter wheel inserted. The filter wheel must always be in one of the five locking positions. ■ The light source has been developed

➧ 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.

for operation in dry rooms only (see point 7 “Technical Data”). ■ Contact with cleaning solvents and

desinfectants as well as oils and oil/air mixtures can induce tension cracks in the light source body. Therefore direct contact with these substances must be absolutley avoided. ■ 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

Safety information: Please read and obey these instructions 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:

2 Operation 2.1 Light guide connection

2.2 Start-up procedure

2.3.1 Electronic adjustment

First open the light guide socket (2) by turning the outer black ring in a counter-clockwise direction. To connect light guides with an 18 mm sleeve diameter, remove the socket adapter. Push the light guide in as far as the stop and close the light guide socket.

Switch on/off by operating the mains switch (1).

The brightness can be adjusted steplessly by turning the light intensity setting knob (3). There are four distinct notched positions between the two end positions of the adjusting knob. These fixed positions, thus ensure the reproducibility of pre-selected brightness settings.

Position : The instrument is switched off. Position I : The instrument is switched on. To protect the halogen lamp the KL 2500 LCD is fitted with a gentle start-up device that reduces the high switch-on current that would otherwise occur. In addition, electronic stabilisation of the lamp voltage ensures stable light power regardless of fluctuations in the mains voltage.

▼

▼

▼

Caution: When inserting light guides with a location pin, care must be taken to ensure that the latter fits into one of the four clamping clip slots.

Position 1 gives the lowest light intensity, and maximum brightness is attained in position 6. The two barriers at positions 4 and 5 are bypassed by pressing in the adjustment knob.

The socket adapter becomes hot during operation. Please ensure that it has cooled down before removal.

2.3 Light intensity setting

The adjustment knob cannot be turned beyond the end stops 1 and 6 respectively.

The KL 2500 LCD is fitted with two independent alternative means to adjust the light intensity.

The lamp lifetime in position 4 is about 1500 hours and in position 5 it is about 150 hours.

The stepless electronic adjustment enables you to optimise the lamp lifetime - by precisely setting the brightness you require, you will achieve the longest halogen lamp lifetime that is possible for your application. This also varies the color temperature of the emitted light.

In position 6 the halogen lamp is operated at its nominal voltage and the lamp will achieve approximately the rated lifetime stated by the lamp manufacturer (depends upon the type).

▼

To remove the adapter, first of all completely unscrew the black ring. Then slightly press the adapter together at the positions marked and remove it. Insertion of the adapter takes place in the reverse sequence.

The mechanical adjustment enables stepless variation of the light intensity at a constant color temperature.

15

The approximate color temperature of the light emitted by the halogen lamp (18) is indicated on the LCD display (5). The color temperature of the light can be set by turning the light intensity adjustment (3) (step width 50 K). After bypassing the barrier at position 5, a lamp symbol (20) appears in the LCD display and flashes for the first few seconds. This acts as a maximum light indication and gives a warning that the expected lamp lifetime will be reduced compared to position 5.

2.3.2 Mechanical aperture

2.4 Supplementary optics

The light intensity can be altered steplessly while retaining the color temperature by turning the adjustment knob of the mechanical aperture (4). Two fixed end-stops and three additional retention points (marked with the letters A to E) enable defined aperture settings to be selected reproducibly.

Use of the supplementary optics ensures that uniform, high-intensity illumination is achieved even when using light-guides with a smaller bundle diameter.

▼

GB

If the illumination is carried out with imaging or focussing optical systems at the light guide exit, optimally uniform illumination is achieved by moving the supplementary optics out of the optical path. Position - Supplementary optics in optical path: uniform illumination with no optical systems at the light guide exit.

▼

Position - Supplementary optics out of optical path: uniform illumination with optical systems at the light guide exit. The supplementary optics must always be positioned at the end stop.

Position A gives the lowest brightness, and maximum brightness is achieved in position E (aperture completely open). Turning the adjustment knob from one retention point to the next approximately doubles or halves the light intensity respectively each time.

▼

The adjustment knob cannot be turned beyond the end-stops A and E respectively.

2.5 Filter wheel

2.5.1 Fitting the Filter

2.6 Remote control connection

The KL 2500 LCD has a filter wheel (7) which can be fitted with a maximum of 5 filters.

Please ensure the light care to ensure that the light source is switched off and has cooled down before removing the filter wheel. There is a warning symbol to remind you.

A remote control and/or inclination angle switch (accessories) can be connected to the light source via the connection socket (8).

Different color and fluorescence excitation filters (available as accessories) can be brought into the optical path by turning the ridged edge of the filter wheel. Please ensure that the filter wheel is always engaged in one of the predefined rest positions. Operating the light source with the filter wheel in an intermediate position can cause the wheel to overheat. The ridged edge of the filter wheel has position markings (the corresponding number of raised marks identifies positions 0 to 4).

▼

▼

To remove the filter wheel, take hold in the depression on the underside of the carrier, pull it out to the stop, lift slightly and then carefully remove. To fit filters into the wheel, remove the cross-head screw and remove the plate holding the filter in place. Insert the filter into the wheel. Push on the plate and tighten the screw. Insert the filter wheel into the guide and push it into the cold light source until it engages. Please ensure that your KL 2500 LCD is operated exclusively with the existing filter wheel. This is the only way to guarantee optimum air cooling of the light source.

The indication “REMOTE” (22) appears in the LCD display when the remote control is plugged in. The remote control can electronically set the light intensity, thus putting the light intensity control knob (3) temporarily out of operation. Both the remote control and the inclination angle switch provide a facility to put the light source into “STAND-BY” mode to protect the halogen lamp. A corresponding indication (21) appears in the display.

▼

Please note the following:

17

In “STAND-BY” mode the appliance is not disconnected from the mains electricity supply. The remote control (or the inclination angle switch) should only be connected and disconnected when the appliance is switched off.

3 Replacing the lamp

4 Maintenance

5 Troubleshooting

Please ensure that the lamp and lampholder have cooled down before replacement. The corresponding warning symbol is attached to remind you.

Your KL 2500 LCD is maintenance-free.

The display has a fault status indicator (19). Any possible breakdowns can be recognized quickly and easily.

▼

To clean the outside of the instrument, use a soft dry cloth or commercially available plastic cleaning cloths. Contact with cleaning solvents and desinfectants as well as oils and oil/air mixtures can induce tension cracks in the light source body. Therefore direct contact with these substances must be absolutley avoided.
