7.19.4 Installing the "Z-axis down" sensor
Æ Thread the sensor cable from the z-axis into the front part of the collect&place head.
Æ Fix the sensor (item 1 in Fig. 7.19 - 1) in position with the screw provided (item 2 in Fig. 7.19 -
1). Initially only screw loosely into the jaw of the z-axis.
Æ Fix the cable into place with the cable clamps.
Æ Check how the cable is run inside the front part of the collect&place head:
– If the z-axis has been pushed right out, the cable should lie loosely around the housing for
the star drive shaft. The cable must NOT be pulled tight.
– If the z-axis is pushed right in, the cable should run freely inside the front part of the col-
lect&place head, without touching the rotary encoder for the DP axis.
CAUTION
If the radius of the curvature is too small, the z-axis could jam or the light barrier cable may
break. 7
Once the cable is run in line with the required conditions, fix it in place with the angled clips
(item 3 and 4 in Fig. 7.19 - 1
). 7
Æ Insert the plug connector for the cable into socket X11 on the intermediate terminal block.
7.19.5 Adjusting the "Z-axis down" sensor
Æ Use the drill to set the distance between the white sleeve ring and the light barrier to 0.95 -1.25
mm.
Æ Fix the light barrier in place with the two screws.
7.19.6 Installing the star
Æ Fit and adjust the star, as described in Sections 7.16.4 and 7.16.5 from page 306 onwards.
Æ Install the front part of the collect&place head, as described in Section 7.6.3 from page 272
onwards.
7.19.7 Adjustments
Æ Use the SITEST program to check that the sensor is working correctly.
