6 Commissioning
• Observe the transport area of the workpiece and make sure that:
– nobody is positioned underneath the workpiece
– there are no foreign objects (e.g.: by providing a protective screen).
• Avoid long tubing sections and large volumes between the suction grippers and the vacuum
module.
• A large volume leads to long exhausting times and possibly incorrect settings on the pressure
sensor.
• Take into account accelerations, external influences, etc. on the work item when setting the
required holding force.
Preparing commissioning
In the base state, the vacuum module is in the RUN mode. The current measurement values are
displayed.
Note
The EDIT button is often used during commissioning to select and confirm values.
In order to avoid damaging the EDIT button please press it using a blunt object.
The base state can be reached from other modes by:
– Pressing the EDIT button for 3 seconds
– Expiration of a monitoring time (timeout section 13 “ Menu structure”)
1. Switch on the operating voltage.
The vacuum module is in the RUN mode.
2. Check the settings of the vacuum module.
Note
An overview of the menu structure can be found in section 13 “ Menu structure”.
Building up the vacuum:
1. Charge the vacuum module with operating pressure via the valve terminal.
2. Switch on the operating voltage for the vacuum module.
After activation of solenoid coil 12 the valve reverts to the “generate vacuum” setting. The
compressed air flows through the vacuum module and generates a corresponding vacuum at the
vacuum connection 3 ( Fig. 5 “Installation”). The maximum vacuum that can be generated
depends on the operating pressure.
Note
The required vacuum may not be generated if there is an insufficient supply of air to the
valve terminal.
