► Read the relevant section in the service manual.
The PCB Camera
► Read the relevant section in the service manual.
Hose on the silencer
► Disconnect the hose on the silencer from the old gantry and fit it onto the new gantry.
CAUTION
Connectors, HCU
► Make sure that the head adapter board is connected to the head interface via a press-fit
connection from below.
► Do not loosen the two screws fastening the HCU.
CAUTION

Fitting the gantry
Fitting the incremental encoder and motor cable
► Fit the incremental encoder. For details, refer to the service manual.
► Pull the protective foil off the scale.
► If there is a corresponding label on the head plate, re-
move this label (1).
► Check the contact surfaces (1) on the new gantry and
trim these if needed with a dressing stone.
► Carefully lift the gantry into the machine and fasten it.
When inactive, one screw at the top (e.g. (9)) is
enough to hold the gantry.
► While doing this, press the gantry downwards, onto
the contact surface of the guide trolley.
► Tighten the screws with a torque of 9.5 Nm. Proceed
as shown, in the order from (1) to (16).
▪ M6x14 screws are used on the top of the gantry.
▪ M6x22 screws are used at the bottom of the gantry.
▪ Replace the threaded bolt with a screw.
CAUTION
Clean the read surface, air gap, cable duct
► Clean the reading surface of the incremental encoder with a cloth and ethanol or with a Q
tip.
► Fit the incremental encoder with a gap of 0.8 mm to the scale.
► Make sure that the axes can be moved without damaging the cables.

Temperature sensor cable
► Fix the cable of the temperature sensor into place. Read the relevant section in the service manual.
Fitting the cable harness and the hoses
► Fit the cable harness and the corresponding hoses to the gantry. For details, refer to the service
manual.
► Connect the cable from the incremental encoder and
temperature control to the gantry interface (1) (see
also "4.1.1 Gantry interface" [ ➙ 69]).
► (2) Connect the motor cable to the gantry interface.
First, use a side cutter to remove the lug (3) on the
connector (2) from the side facing the middle of the
gantry interface . Fasten the cable to the other lug
with a cable tie.
► Continue to secure the cable so that it does not get
caught in the trailing cable running next to it.
CAUTION
Cable routing
► Make sure that the end stops (red buffers) do not rub against the cable of the board.
► Make sure that the cable for the board can not collide with the X axis end stopper.
CAUTION
Always handle the trailing cable with care
► If a vacuum pump is fitted, also observe the relevant assembly instructions [00196845-xx].
► Always handle the new trailing cable with care.
► Make sure that the flat ribbon cable and the pneumatic hoses are not rubbed against any
parts or folded. Look out for sharp edges.
► Clean the trailing cable contact surface on the machine base with a dry cloth.
► Carefully insert the trailing cable into the prescribed position. Make sure you do not twist it.
► Take care of the rubber mat under the holder.
► Check that the power track chain runs parallel to the machine base. Move the gantry back
and forth.
► Secure with screws with Loctite 243.
► If it is difficult to push the hoses onto the tubes, moisten these first with ethanol or isopro-
panol (IPA).
► Fit the board cover. Make sure that you do not cause a short circuit.
