NOTE:

Make sure that both ends (2) of the

tension jack lie on the teeth of the

toothed belt (1) .

NOTE: New tension jack

A new tension jack (fitted from 10/

2007) has a profile which engages with

the toothed belt and therefore ensures

a more reliable clamping.

X Loosely screw in the four M3x5 hexagon

socket-head screws (1) on the Z axis drive unit

(2).

X Tension the Z axis toothed belt (7) by pushing

the Z axis drive unit upwards.

X Check the toothed belt tension with the belt

tension measuring device.

X Tighten the two M3x14 hexagon socket-head

screws (6) to fix the motor clamp (5).

X Fix the motor clamp 2 (4) with the two

M2.5x12 hexagon socket-head screws (3).

X Now tighten the hexagon socket-head screws

on the Z axis drive unit and the motor clamp.

X Dismantle the front part of the C&P head.

X Dismantle the star.

X Remove the plug from the slot on the

intermediate distributor.

X Push the Z axis down.

X Loosen the screws holding the sensor (2).

X Remove the cable clamps on the driver arm

and star motor.

X 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.

X Thread the sensor cable from the Z axis into

the front part of the C&P head.

X Fix the sensor (1) in position with the screw

provided (2) and initially screw loosely into the

jaw of the Z axis.

X Fix the cable into place with the cable clamps.

X 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,

without touching the rotary encoder of the DP

axis.

ATTENTION: 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.

X Once the cable is run in line with the required

conditions, fix it in place with the cable clamps.

X Connect the cable plug to the slot on the

intermediate distributor.
