6.3.10 Setting the Mechanical Position of the Valve Positioning Drives
Set the motor position of the valve positioning drives "pickup/placement" and "reject" as shown in the
following diagram.
If the new valve plungers are used (s. diag. below) proceed as follows: Take out one valve plunger
and remove the sleeve (2).
Insert the plunger without bushing and carry out the following steps on this segment:
Insert the distance gauge (0.2 mm) between valve plunger and valve casing.
Rotate the valve positioning drive 90 degrees from its initial position. The eccentric of the valve
adjustment drive will just touch the inner side (1) of the valve plunger.
Fix the motor of the valve drive in this position.
Remember to replace the tube on the valve plunger.
6-18: Setting the mechanical position of the valve drive
Set the motor position of the valve positioning
drives "pickup/placement" and "reject" as shown in
the diagram.

X If the new valve plungers are used (s. diag. on
left) proceed as follows:
Take out one valve plunger and remove the
sleeve (2).
Insert the plunger without bushing and carry
out the following steps on this segment:
X Insert the distance gauge (0.2 mm) between
valve plunger and valve casing.
X Rotate the valve positioning drive 90 degrees
from its initial position. The eccentric of the
valve adjustment drive will just touch the inner
side (1) of the valve plunger.
X Fix the motor of the valve drive in this position.
X Remember to replace the tube on the valve
plunger.

NOTE:
Use a nozzle of type 914 to set the air
blast. Press in the spring from the
nozzle interface during the
measurement and read the value from
the display.

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.
