Installation

1. Z axis drive

2. Z axis toothed belt

3. 2 x deflection wheel / DLM3

4. Tension jack (Z axis clamping device)

► Switch off the machine and secure it to prevent unau-

thorized reactivation.

► Loosen the two screws fastening the tension jack (3).

► Loosen the two M2.5x12 hexagon socket-head

screws (3) on the motor clamp fitting (4).

► Loosen the two M3x14 hexagon socket-head screws

(6) on the motor clamp fitting (5).

► Slightly loosen the four M3x5 hexagon socket-head

screws (1).

► Remove the toothed belt (7).

► Place the new toothed belt over the pinion of the Z

axis drive and the deflection wheels.

NOTICE!

Make sure that the teeth of the toothed belts engage in

the teeth of the pinion and deflection pulleys.

► Fit the tension jack (4) with the two fastening screws,

to the toothed belt.

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.
