Pressure Control Valve (PRV)
1. Energy and data supply
2. Compressed air connection
3. Vacuum/air kiss for pickup/placement
circuit
4. Discharged air for cooling the X linear
motor
5. Mounting for pressure control valve
●
The PRV supplies the pickup/placement circuit with vacuum during the pickup process and
switches over to air kiss during placement.
●
The valve can be replaced during service work.
●
Sensitivity against dirt and dust is reduced (protection diaphragm).
A - Piston in "open" position
B - Piston in "closed" position
1. Venturi nozzle
2. Plunger (iron core)/ piston
3. Plunger drive (inductor)/ driver circuit
4. Discharged air
5. Vacuum/air kiss for pickup/placement
circuit
6. Compressed air inlet
●
During pickup, the piston is always in the "open" position; vacuum is produced and applied to
nozzle for pickup.
●
During placement, the piston is in the "close" position, air kiss is produced and applied to
nozzle for placement.
●
In the placement cycle the time to switch between maximum vacuum (-850 mbar) to maximum
air kiss (+400 mbar) is < 12ms.

5.2.4.3 GUI – How to Perform a Vacuum Check
In the case of vacuum errors the vacuum system can be tested using the station software.
For the pickup/placement circuit the differences between open and closed values are evaluated,
for the holding circuit the absolute value is measured.
1. Check Vacuum values tab
2. Nozzle vacuum detailed results
3. Nozzle vacuum check status
4. Head function menus
5. Click Measure vacuum values to start new check.
When vacuum results are bad the segment/segments affected are highlighted.
Example: Error occur on segment 3
