Operating principle
When the device is switched on, a xenon lamp is ignited. The xenon lamp
is operated under output control.
The xenon lamp generates free-burning discharge arcs between two elec-
trodes in pure xenon gas. The small gap between the electrodes allows for
creation of a source of illumination closely resembling that of a spotlight.
The light is filtered through the cold light reflector, propagated through
the optical cable and directed to the field of view (operative field).
Monitoring the operating time of the xenon lamps
The xenon light source OP930 is fitted with an operating time counter that
registers the number of hours the lamp has been in operation. During
operation, the xenon lamp OK display 4 is illuminated. If a lamp operating
period of 500 hours is exceeded, the change lamp indicator 8 comes on.
Monitoring temperature
In order to safeguard the xenon light source against overheating, the
operating temperature of the power supply unit and xenon lamp are con-
tinuously monitored. If the limiting temperature is exceeded, the xenon
lamp switches off. The fan is activated during the cooling phase. The
xenon light source can be used again after a brief period.
Brightness control
The desired brightness can be continuously adjusted with the brightness
control 5.

Preparation and setup
Danger of explosion from a device that is improp-
erly set up!
►
Do not use the device in explosion-hazard areas.
DANGER
►
Make certain that the power plug is connected
to the power supply outside of any areas where
there is a risk of explosion.
Non-compliance with the following instructions will preclude all respon-
sibility and liability in this respect on the part of Aesculap.
►
When setting up and operating the product, adhere to
– national regulations for installation and operation,
– national regulations on fire and explosion protection.
Note
For the safety of patients and users it is essential that the mains power cord
and, especially, the protective earth connection are intact. In many cases
defective or missing protective earth connections are not registered imme-
diately.
►
Connect the device via the potential equalization terminal at the rear
panel of the device to the potential equalization system of the room
used for medical purposes.
Note
The potential equalization lead can be ordered from the manufacturer as
art. no. GK535 (4 m length) or TA008205 (0.8 m length).
3.1
First use
