5.4.9.9 Fitting the front part of the collect&place head
➠ Remove the gauge for the star.
➠ Insert the power cable plug connector for the star drive into socket X5 on the intermediate
terminal block. The plug connector is an anti-rotation connector.
➠ Fit the front part of the collect&place head on the back part of the collect&place head (see
section 5.4.3.3
, page 5 - 39).
5.4.9.10 Fitting the intermediate distribution board
➠ Restore connections X1 ... X12 as described in Table 5.4 - 2.
➠ Push the hose onto the pressure sensor tube (see item 4 in Fig. 5.4 - 17).
➠ Fix the intermediate distribution board in place (see item 2 and 3 in Fig. 5.4 - 17).
➠ Fix the protective cover to the head.
➠ Switch the placement system on and start it up.

5.4.10.4 Fitting the rotary encoder
– Insert the new rotary encoder and initially fix in place loosely with the two M2.5x8 hexagon
socket head screws (item 3 in Fig. 5.4 - 22
).
– Insert a sleeve into the star and turn the star with the sleeve until it reaches the rotary encoder.
– Fix the star in this position using the gauge for the star.
– Adjust the rotary encoder so that the distance between the rotary encoder window and the
incremental disk on the sleeve is 1.5 mm (see Fig. 5.4 - 23
).
The procedure is as follows:
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
RISK OF BREAKING THE INCREMENTAL DISK 5
➠ Carefully push the pointed end of the test probe between the window of the incremental
encoder (item 1 in Fig. 5.4 - 23
) and the incremental disk (item 2 in Fig. 5.4 - 23).
➠ Loosen the fixing screws for the incremental encoder if you cannot push the test probe in
easily.
PLEASE NOTE:
The test probe has a blunt end and a pointed end. Only push the pointed end of the test probe
between the incremental encoder and incremental disk of the sleeve to avoid scratching the
disk, and thus causing counting errors. 5
➠ Carefully push the rotary encoder towards the incremental disk and along the stop edge (item
A in Fig. 5.4 - 23
) until the test probe lies flat against the incremental disk (item 2 in Fig. 5.4 -
23) and the window of the rotary encoder (item 1 in Fig. 5.4 - 23).
➠ Fix the rotary encoder in place using the two M2.5x8 hexagon socket head screws.
➠ Carefully pull the test probe out of the gap.
