MJB4 - Warnings and Safety Rev02 01-06

To begin operating the machine again, the main
switch must be turned to ON and the machine must
be restarted.
1.5. Dangers
1.5.1. Physical Dangers
Moving machine parts such as the alignment station,
microscopes and their manipulators, the mirror
housing and others can cause injury to the operator.
You should take particular care of the movements of
the microscscope if your machine is equipped with
the direct microscope viewfinder.
Moving machine parts can injure the
fingers or face.
Do not remove any materials from the
machine until all machine movements
have stopped!
With a machine equipped with a vibra-
tion-damped underframe, the base
plate can sink without warning in the
event of a drop in pressure in the com-
pressed air supply.
Never place the hands between the
base plate and the vibration-damped
underframe of the machine!
The movement of a direct viewfinder
can cause injury to the eyes or face.
Stop looking into the microscope view-
finder before you start the microscope
movement!
A particular danger results from the
fragments thrown out in the event of a
lamp explosion!
Situations which can lead to a lamp ex-
plosion are described in a separate
section.
You should also be aware of the risk of
poisoning with Hg following a lamp ex-
plosion; this is also described in a sep-
arate section.
1.5.2. Thermal Dangers
The upper side of the lamp house gets very hot dur-
ing operation.
Operating temperatures of several hundred °C occur
on the lamp itself.
The lamp cooling must be correctly adjusted accord-
ing to the lamp type!
There is a risk of lamp explosion if the
lamp house is opened prematurely
while the lamp is hot.
The exposure lamp has to cool down
for at least 20 minutes before the lamp
house door is opened!
The controlled cooling required for
more powerful lamp types must also be
left in operation during the cooling
phase!
1.5.3. Electrical Dangers
Live parts may be exposed when the machine cover
is removed.
High wattages and currents of up to 50 A can occur
in the lamp and lamp power supply.
The lamp starting voltage can be up to 30 kV.
Do not open the machine until the
whole machine has been isolated from
the power supply!
Pay attention to this warning symbol on
covers!
Where applicable, observe local "log
out - tag out" regulations!
The individual electrical assemblies, especially bal-
lasts CIC1200, CPC200 and CPC350, contain no
parts which the user could repair or adjust.
1.5.4. Radiation Danger
The high luminous density of the exposure lamp can
cause eye damage.
In particular, the invisible ultraviolet component of the
light can lead to permanent eye damage or skin
burns.
UV light can acutely or permanently
damage your eyes.
Covers over the ray path may not be re-
moved while the UV lamp is switched
on!
Lamp adjustment work may only be
carried out with UV-protective goggles
- also with skin protection in the case of
intensive radiation!
