6.3.11.3 Setting the Air Blast Pressure Values with the Compressed Air Testing Device

Adjust to the values of the table below:

Repeat these adjustments several times, as the pickup / placement circuits are mutually dependent.

6-21: Flow chart determining air pressure values

When setting the air blast value with the

compressed air device and the adjustment valve,

observe the following:

X Press the nozzle upwards during the

measurement process!!

NOTE:

The air blast values which are shown in

the

Measured Air Blast

menu, on the

station computer screen, at

Single

Functions

or in the SITEST program,

do not reflect the air blast values really

set at the nozzle. They are used to

check that the air blast valve is

functioning correctly. Therefore, do not

use the values shown on the screen to

set the air blast. Instead, use only the

values determined with the

compressed air testing device.

Air Pressure Values Set with compressed air testing device

Measured at nozzle:

Displayed on the monitor:

(Only in pickup and placement

circuit)

pickup / placement circuit 150 mbar (100 - 200 mbar) e.g.: 250 mbar

Reject circuit 250 mbar (200 - 300 mbar) Reject circuit does not have a sensor

NOTE:

The two air blast circuits are controlled via a single valve and therefore influence one another

mutually. However, two different adjustment valves (see items 3 and 4 in the diagram above)

can be used to set the various pressures for each circuit.

NOTE:

Make sure the measurement sensor hose is fitted tightly on the nozzle.

C&P12 Performing a Vacuum Test on the C&P 6/12 DLM Heads

234 Service Manual SIPLACE D4

6.3.12 Performing a Vacuum Test on the C&P 6/12 DLM Heads

Damage to the valve plunger, silicone hose, the vacuum plate, in or on the nozzle can lead to leakage

which may then cause malfunctions during the placement process or which may reduce the vacuum

value in the holding circuit.

Vacuum test with normal nozzle

configuration

 The vacuum tests for C&P6/12 in the station

software of the C&P12/6 placement heads

only checks the area from the vacuum

generator to the valve plungers.

 The area visible here (red frame), from the

valve plunger housing via the silicone hose

into the segment housing and through the

sleeve to the nozzle is not covered by the

normal vacuum test.

Equipment required

Closed nozzle tips are required for checking the

complete vacuum circuit.

The special nozzle use for this is marked red and

does not have a nozzle configuration on it:

 SOKO nozzle for vacuum test DLM, Item No.
