Commissioning
Observe the transport area of the workpiece and make sure that:
–
Nobody is positioned underneath the workpiece
–
There are no objects within the transporting path of the workpiece (e.g. by means of a protective
screen).
Avoid long tubing and large volumes between the suction grippers and vacuum block.
A large volume leads to long evacuation times and possibly incorrect settings on the pressure
sensor.
Take into account accelerations, external influences, etc. on the work item when setting the re
quired holding force.
Preparing commissioning
In the basic status, the vacuum block is in 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 basic status can be reached from other modes by:
–
pressing EDIT button 3 s or
–
Expiration of a monitoring time (timeout
è
Chapter 13 “ Menu structure”)
1. Switch on the operating voltage.
è
The vacuum block is in RUN mode.
2. Check the settings of the vacuum block.
An overview of the menu structure can be found in chapter 13 “menu structure”.
Building up the vacuum:
1. Charge the vacuum block with operating pressure via the valve terminal.
2. Switch on the operating voltage of the vacuum block.
è
After activation of solenoid coil 12, the valve reverts to the Generate Vacuum setting. The com
pressed air flows through the vacuum block and generates a corresponding vacuum at the vacu
um port

(
è
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.
