NOTICE!
Make sure that both ends (2) of the tension jack lie on the
teeth of the toothed belt (1) .
NOTICE!
New tension jack
A new tension jack (fitted from 10/2007) has a profile
which engages with the toothed belt and therefore en-
sures a more reliable clamping.
► Loosely screw in the four M3x5 hexagon socket-head
screws (1) on the Z axis drive unit (2).
► Tension the Z axis toothed belt (7) by pushing the Z
axis drive unit upwards.
► Check the toothed belt tension with the belt tension
measuring device.
► Tighten the two M3x14 hexagon socket-head screws
(6) to fix the motor clamp (5).
► Fix the motor clamp 2 (4) with the two M2.5x12 hex-
agon socket-head screws (3).
► Now tighten the hexagon socket-head screws on the
Z axis drive unit and the motor clamp.
► Check the Z axis top stop with the setting gauge.

Installation
Adjusting the "Z axis down" sensor
► Set the distance between the white sleeve ring and the light barrier to 0.95 -1.15 mm.
⇨ Use a test probe or drill (diameter 1.0 mm) for this.
⇨ Check the distance with a test probe or drill (diameter 1.2 mm). – This drill should not fit!
1. "Z axis down" sensor
2. Fixtures for sensor
3. Plug for intermediate distributor
► Dismantle the front part of the C&P head.
► Dismantle the star.
► Remove the plug from the slot on the intermediate
distributor.
► Push the Z axis down.
► Loosen the screws holding the sensor (2).
► Remove the cable clamps on the driver arm and star
motor.
► Carefully pull the sensor and cable out of the front
part of the C&P head and remove the plug (3) from
the socket on the intermediate distributor.

► Thread the sensor cable from the Z axis into the front
part of the C&P head.
► Fix the sensor (1) in position with the screw provided
(2) and initially screw loosely into the jaw of the Z ax-
is.
► Fix the cable into place with the cable clamps.
► Check how the cable is run inside the front part of the
C&P 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 C&P head, with-
out touching the rotary encoder for the DP axis.
CAUTION!
Check how the cables are run!
If the radius of the curvature is too small, the Z axis could
jam or the light barrier cable could break.
► Once the cable is run in line with the required condi-
tions, fix it in place with the angled clips.
► Connect the cable plug to the slot on the intermediate
distributor.
