SAFETY INFORMATION
30.30.01.00559/05 | 06.2020
1.5 Intended use
The Vacuum-Operation-Center (VOC) is intended to control and maintain a specific vacuum and act as a
liquid separator.
Appropriate safety precautions on systems and units that are used in connection with the VOC must
prevent any risks to individuals, animals or property as a result of a loss of operating vacuum.
A machine or system pursuant to Machinery Directive 2006/42/EC with the relevant safety installations is
required in order to use the VOC.
The VOC is exclusively intended to control and maintain a specific operating vacuum that is used to
fasten certain workpieces to an appropriate clamping device or to handle appropriate workpieces with the
relevant handling system.
The VOC is specifically designed for evacuating media with a liquid content and can be used to generate
a vacuum for machinery in wet machining areas. Chips or other small solids contained in the separated
liquid can be separated from the evacuated medium and do not impair the function of the VOC in small
quantities.
The water content in the liquid may not fall below 70%.
The integration of the VOC into the overall machine is the responsibility of the manufacturer of the overall
machine or the machining centre. The VOC is equipped with supply lines, sensors and actuators.
Before commissioning, the VOC supply lines must be connected in accordance with the descriptions
provided in Chapter 5 and the transmitting electrical lines must be connected to the overall machine
control unit via a multi-pole plug. The manufacturer of the overall machine is responsible for the further
processing of these electrical signals.
For example, the use of the VOC signals must ensure that the machine release to process workpieces is
interrupted when the supplied liquid reaches the critical fill level and if the vacuum level falls below -600
mbar.
Any other use that deviates from the intended use is not permitted and may lead to dangerous situations!
The VOC is:

not intended to suck in body parts and other living creatures and

not designed for mechanical loads of any kind.
The evacuation of items with an implosion risk and unauthorised media is prohibited in any form.
Unauthorised conversions and changes to the VOC are prohibited for reasons of safety!
