[. . . ] The manuals "ebq 100 dc ­ Electronic transformer for the N HBO 103 microscope illuminator" and "ebx 75 isolated ­ Electronic transformer for the N XBO 75 microscope illuminator" must be observed. Special regard must be paid to the notes on instrument safety included in this manual. The data sheets from the lamp manufacturers must be observed when the HBO 103 and XBO 75 lamps are operated. To guarantee the safe operation and function of the N HBO 103 and N XBO 75 microscope illuminators, it is necessary under any circumstances to take the precaution measures and observe the warnings contained in the operating instructions.  1. 2 NOTE! Notes which must be observed when using the N HBO 103 and N XBO 75 microscope illuminators. Regulations concerning Instrument Safety and Electromagnetic Compatibility (EMC) The following symbols are used for the warnings: The N HBO 103 and N XBO 75 microscope illuminators have been designed and tested in compliance with EN 61010, Part 1 (VDE 0411). [. . . ] - Clean the housing of the microscope illuminator when it is dirty. To enable the microscope illuminators to function perfectly, it is necessary to use only components and spares marketed or admitted by us. With the exception of the work described in this manual, the user must not perform any repairs or changes himself. We would like to emphasize that all other changes and repairs must be performed by specially authorized personnel. Defective instruments or components may only be repaired and maintained by our service department. Do not use any solvents. Soak a cleaning cloth in a mixture of water and washing-up liquid, remove the dirt and dry the housing using a clean cloth. - After expiry of the average operating time (see data sheets from the lamp manufacturers), the lamps must be exchanged; there is a risk of explosion!The operating time of the HBO 103 and XBO 75 can be checked on the counter of the relevant transformer. 8) The intensity of the lamps decreases when the operating time increases, i. e. homogeneous illumination of the object field can then no longer be guaranteed. - Before each lamp exchange, make sure to allow the N HBO 103 or N XBO 75 microscope illuminator to cool down sufficiently long in order to reduce the pressure; wait at least for 15 minutes! 1. 6 Hints on Disposal Used HBO 103 and XBO 75 lamps and defective microscope illuminators should not be treated like domestic waste; they should be disposed of in their original packaging in accordance with the legal regulations. When in doubt, please contact the Carl Zeiss microscopy service. 1. 7 Hints on Warranty The instrument manufacturer is not liable for damage caused by unauthorized operation, particularly the removal and exchange of components, or the use of accessories from other manufacturers. This forfeits all the claims against warranty. 6 B 40-065 e 08/99 N HBO 103 and N XBO 75 Microscope Illuminating Systems Instrument Description Components, Catalogue Numbers Carl Zeiss 2 2. 1 Instrument Description Components of the Microscope Illuminating Systems The N HBO 103 and N XBO 75 microscope illuminators include the following components (Fig. 2): - Illuminator with: dovetail for attachment to the microscope, reflector, double-lens collector or quartz collector for UV light, heat-protection filter - HBO 103 W/2 mercury vapor short-arc lamp or XBO 75 W/2 xenon short-arc lamp - transformer ebq 100 dc for N HBO 103 or transformer ebx 75 isolated for N XBO 75 - line cable with earth-contact plug or line cable with American flat plug 1 2 3 4 Lamp housing Connecting cable Collector Dovetail 5 Lamp base 6 Transformer ebq dc 7 Line cable Fig. 4 Line spectrum of the XBO 75 xenon short-arc lamp B 40-065 e 08/99 9 Carl Zeiss Start-Up HBO 103 Lamp Insertion/Change N HBO 103 and N XBO 75 Microscope Illuminating Systems 3 3. 1 Start-Up N HBO 103 Microscope Lamp Lamp Insertion/Change - Before inserting the lamp, make sure that no connection to the line is available. - The lamps may only be changed when they are cooled down; allow the microscope illuminator to cool down for 10. . . 15 minutes to avoid the risks of burns and explosion!- The lamp may only be removed from the packaging and inserted in the microscope illuminator if a protection mask and safety gloves are worn (see chapter 1. 3). - All clamping adjustments must be performed carefully; pronounced heat during operation may result in loose contacts. 1 2 3 4 5 6 7 Fig. 5 Insert HBO 103 lamp Fixation screw for lamp housing Control wheel for collector Cooling body Fixation screw for lamp mount in cooling body Spring lever Lamp mount Lamp 10 B 40-065 e 08/99 N HBO 103 and N XBO 75 Microscope Illuminating Systems Start-Up HBO 103 Lamp Insertion/Change Carl Zeiss Procedure: · Switch off the transformer · Disconnect the microscope lamp housing from the transformer · Allow the microscope lamp housing to cool down for 10. . . 15 minutes · Wear protection mask and safety gloves. · Remove microscope lamp housing with cooled-down lamp from the microscope · Move collector in front position by turning the control wheel (5-2) in the direction of the arrow · Loosen fixation screw (5-1) for lamp housing; remove the lamp housing · Press spring lever (5-5) downwards to loosen the lamp locking; remove defective lamp (5-7) with cooling body (5-3) from the mount (5-6) in the lamp base. · Loosen fixation screw (5-4) on the cooling body: remove defective lamp and dispose of it in accordance with the appropriate regulations (see section 1-6 - Notes on disposal) For initial start-up, remove the safety appliance first. · Insert cathode (smaller base) of the new lamp into the cooling body until stop; Do not exert any force when inserting the lamp. · Attach lamp housing to the lamp base; make sure that the contact pin fits into the provided opening; tighten fixation screw for lamp housing. · Insert lamp with cooling body in the relevant mount in the lamp base and make sure that the lateral lead to the cooling body remains accessible; use the spring lever for fixation.
