NOTE
Air pressure values, displayed on the screen of the station computer, under option "Measure air
pressure" of the "Single functions", or in the SITEST program, do not correspond to the air
pressure values actually set at the nozzles.
They solely serve to check that the forced air valve is functioning correctly.
Therefore, the air pressure may not be adjusted with the values displayed on the screen.
Instead, use only the values determined with the compressed air testing device.

Å Adjust to the values of the table below:
NOTE
Both forced air circuits are controlled by a single valve and therefore are mutually dependent.
Using two different restrictor valves (compare item 3 and 4 in fig 7.3 - 3), it is however possible, to
adjust differing pressure values for each circuit.
Å Repeat these adjustments several times, as the pick - up / placement circuit are mutually
dependent.
NOTE
Make sure that the test sensor tube is attached air - tight on the nozzle.

Å Remove sleeve 1 and insert the star zero point gauge, in order to mechanically fix the star.
Å Now, remove sleeve 4 as well and align the transducer.
Å With the help of a parallel pin, set the digital transducer of the dp - axis to 1.5 mm, parallel to
the glass pane of the segment.
NOTE
A parallel pin of 1.4 mm must easily fit through the gap, a parallel pin of 1.6 mm must be too big
to fit.

Å Set the motor position of the valve drives "Pick-up / Placement" and "Ejection" according to the
figure below.
Å Insert the distance gauge between valve plunger and valve casing.
Å Turn the valve drive to 90° degrees, opposite to its initial position.
