5.5.3.3 Adjustments of the Air Pressure Values with the Help of a Compressed Air Testing

Device

fig 5.5 - 4 Flow chart determining air pressure values

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. 5

➠ 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. 5.1.10), it is however possible,

to adjust differing pressure values for each circuit. 5

➠ 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. 5

5.5.4 RSF Digital Rotary Transducer of DP - Axis

5.5.5 RSF Digital Transducer of DP - Axis

➠ Remove sleeve 1 and insert the star zero point gauge, in order to mechanically fix the star.

➠ Now, remove sleeve 4 as well and align the transducer.

➠ 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. 5

5.5.6 Light Barrier, Bottom Position

NOTE

In order to adjust the light barrier, use a parallel pin and adjust it to a distance of 1.33 mm to the

sleeve. 5

5.5.7 Adjustment of Mechanical Position of Valve Drives

➠ Set the motor position of the valve drives "Pick-up / Placement" and "Ejection" according to the

figure below.

➠ Insert the distance gauge (0,2mm) between valve plunger and valve casing.

➠ Turn the valve drive to 90° degrees, opposite to its initial position.

5.5.8 Other Mechanical Adjustments on the Star

➠ Insert the blast air transition tubes so that they will protrude 0.5 mm from the surface of the

circular arc guide.
