2.1.3 Compressed Air Supply
Even small amounts of water in the compressed air can lead to a corrosion of the carrier.
Other contaminations can also result in malfunctions. Use only compressed air fulfilling
the following standards.
 The air must be absolutely free of water, oil, and any particles.
 When air is compressed, the humidity in the air is concentrated into a smaller area, frequently
condensing inside the air hoses. Use a water separator to remove water from the air. The
provided water separator is not suitable to establish the necessary conditions; it serves only
as a control device. If you regularly observe an accumulation of water in the provided water
separator, the compressed air does not fulfill the required standards.
Warning: Water in the system leads to corrosion and destroys the device!
This is extremely important!
 Use a filter with 5 μm pores or smaller to remove any particles from the air.
 Set the external air pressure at least to 5 bar, the maximum pressure of 10 bar must not be
exceeded. Adjust the provided pressure regulator to 3 bar, too high or too low pressure can
lead to malfunction and can severely damage the device. Check the pressure at the end of the
pressure line, directly before it is lead into the Roboinject. The Roboinject needs a minimum
flow rate of 20 l/min.
 Do not use other compressed air hoses than those provided, that is, ID 4 mm OD 6 mm from
compressor to water separator, and ID 2.5 OD 4 mm from water separator to the Roboinject.
The use of other hoses could lead to a decrease of pressure.
2.1.4 Handling of the Carrier
 Do not try to lift the carrier off the x/y table. You may move the carrier carefully sideways
by hand if necessary but not during operation. For cleaning or alignment purposes use the
appropriate software control, please read chapter "Maintenance" and "Alignment".
 If it happens that any liquid spills over the x/y table, please remove it as soon as possible
in order to prevent a corrosion of the carrier.
2.1.5 Handling of the Injector Mount ( = z-Axis)
 Do not move the z-axis by hand. Breakage may occur. Always use the software controls
to move an axis up and down, please see chapter “Manual Mode".
 Change the injection needle with great care. The injection needle is sharp and may lead
to injuries. Stay at a safe distance during operation and protect your eyes. Especially take
care not to move your hands in the range of the z-axis.
2.1.6 Handling of Injection Needles
 The injection needles are sharp and break easily. Always handle them with care.
 In rare cases, a needle may splinter when inserting the plunger into the needle and fitting it.
Stay at a safe distance and protect your eyes.
 Dispose the used injection needles into an appropriate container.
2.1.7 Regular Backups
 You (or the administrator) should perform backups of the Roboinject plate files (*.rpf files) and
template files (*.rit files) at regular intervals and to appropriate media for preventing data loss.
Data loss may be caused by power failure, system and software errors.
