G-30-1346-en S8 Floor Stand Issue 4.0
Printed on 05. 06. 2001
Halogen illumination system
The stand is equipped with two separate illumination systems for fiber il-
lumination. Each of the two lamp housings contains a backup lamp which
will be automatically activated if the first lamp fails. Only one of the two
illumination systems is required for normal operation of a surgical micro-
scope. The second illumination system can be used, for example, for a
fiber slit lamp or a dual fiber illumination system.
1 Lamp module
2 Ventilation grid
Do not cover the ventilation grid! Make sure that drapes do not cover
the grid. This can lead to overheating of the lamp modules and to lamp
failure.
3 Flap
The flap is the mechanical indicator for the operating status of the hal-
ogen lamps.
– When the flap is closed, the main lamp is operative (green light (9)
is on).
– When the flap is open, the main lamp has failed. The backup lamp
is operative (yellow light (8) is on).
4 Manual activation of the backup lamp
If the automatic activation system fails, press this button to switch on
the backup lamp.
5 Opening the lamp module
When you press this button, the lamp module is slightly ejected. Pull
out the lamp module all the way for lamp change.
