Requirements
– Vacuum suction nozzle mounted
– Pneumatic connection of the vacuum nozzle.
– Compressed air supply switched on.
– Electrical connection of the vacuum suction nozzle.
– Power on.
Procedure
Ensure that in the transport area of the workpiece:
•
No one is under the workpiece
•
there are no foreign objects (eg: through protective grilles)
•
Avoid long hose lines and large volumes between suction pads and vacuum nozzle. A large volume
leads to long evacuation times and possible adjustment errors on the vacuum switch.
•
Consider accelerations, foreign influences etc. on the work piece when adjusting the necessary holding
force.
To construct the vacuum:
•
Apply pressure to the VN -...- P with an operating pressure. This creates a corresponding vacuum at the
vacuum connection. By varying the operating pressure, the vacuum is adjusted. The workpiece must be
held securely against the suction pad by the generated vacuum.
To adjust the vacuum switch:
•
The setting of the vacuum switch for monitoring the vacuum depends on the application.
•
Switch on the operating voltage. The VN -...- P is in the basic state.
•
Definition
Switching pressure SP
Vacuum at which the VN -...- P switches.
Teach pressure TP
Vacuum at the time of programming
Set the switching pressure in the EDIT mode as follows:
1.
Apply pressure to the VN -...- P using a teach pressure (eg: TP1). The sequence of the teach pressure is
irrelevant.
2. Press the Edit button until the LED starts flashing. When released, the VN -...- P stores the first teach
pressure. The LED continues to flash.
3. Apply VN -...- P to the other teach pressure (eg: TP2).
4. Press the Edit button until the LED stops flashing. When released, the VN -...- P stores the second teach
pressure and terminates the EDIT mode. The relationship between teach pressure, switching pressure
and hysteresis is shown in the following table. For the VN -...- O1-P, the switching pressure is formed
from the mean value at the teach pressure (SP = ½ (TP1 + TP2)). With VN -...- O2-P the higher Teach
pressure becomes the switching pressure.
Check the VN -...- P as desired in a test run with alternating pressure. The LED is illuminated parallel to the
programmed switching behavior
