3.3.1 Replacing the Trailing Cable Gantries

Service Manual (internal version) SIPLACE HF and X Series 41

Removal

► Loosen the flat ribbon cable on the trailing cable interface gantry (1). Take care not to lose the brack

ets for the press-fit connections. They could fall out and be lost.

► Remove cable ties where necessary.

► Remove the necessary cable ties at the gantry interface (4) and disconnect the flat ribbon cable.

► Disconnect the motor, proximity switches, incremental encoder and temperature sensor cables from

the gantry interface (4).

1. Trailing unit interface gantry

2. Pneumatic for vacuum pump (option)

3. Mount for trailing cable

4. Gantry Interface

CAUTION

Note the order in which the terminal connections are arranged.

► Label the press-fit connections to the flat ribbon cables, for easier reconnection later.

NOTICE

Refitting the gantry interface board.

The gantry interface board is installed on the mount of the new trailing cable.

To sever the pneumatic hoses, which lead to the pneu

matic distributor inside the machine base, proceed as fol

lows:

► Place the gauge (1) on the mount (3).

► Use the gauge to label the hoses at the Y hose mark

(2).

CAUTION

Before cutting the pneumatic hoses

► Label the order of pneumatic hoses (from 1 to 7 – inside to outside). This is important to

ensure that the hoses are then correctly connected again after cutting.

► During cutting, make sure that the pneumatic hoses do not fall into the machine base. Se

cure them accordingly.

Gantries 3.3.1 Replacing the Trailing Cable

42 Service Manual (internal version) SIPLACE HF and X Series

► Disconnect the hoses from the pneumatic distributor (7).

► Undo the four screws (6) fastening the trailing cable console and carefully remove the complete trail

ing cable from the machine. The fastening screws have been secured with Loctite.

► When you replace an old trailing cable with a new one, you also need to remove the hotlink card

(including fixtures) and the Vision board spread spectrum.

► Loosen the screws fastening the trailing cable mount

(3) .

► If the option "Vacuum pump" is available, loosen the

pneumatic hoses (2) and follow the instructions in the

Retrofit Guide Vacuum Pump[00195089

01].

► Secure the end of the trailing cable (with cable ties) in

the machine to prevent it hanging loosely and damag

ing other machine components.

► Disconnect the flat ribbon cable (1) from the head

board (2).

► Disconnect the camera cable (3) from the head board

(2).

► Undo the screws fastening the X trailing cable clamp

(4) and the two clamps (5) on the back of the gantry.

NOTICE!

Clamp remains intact

Only loosen the fastening screws. The clamps for the flat

ribbon cable remain in place.

Mark the installation position of the contact disks and

spacer bolts and take care not to lose them. These will

need to be correctly replaced later.

WARNING

Risk of injury to hands

► Use the hose unlocking tool to remove the hoses [03047090-xx].

3.3.1 Replacing the Trailing Cable Gantries

Service Manual (internal version) SIPLACE HF and X Series 43

Installation

► If you replace a trailing cable which is of

version 1 from B-079-B

with a trailing cable which is of

ver

sion 2 after B-079-B

, first replace the new "Vision hotlink adapter VHA assembly" [03054633-xx] and

the "Vision board spread spectrum (VBSX) assembly." [03054634-xx].

► Carefully insert the new trailing cable (1) into the prescribed position. Make sure you do not twist it.

► Temporarily fasten the ends to the machine base (e.g. by tying them).

► Fit the gantry interface board (5) onto the holder (4) of the new trailing cable.

► Reconnect all compressed air connections at the pneumatic distributor. Observe the correct con

nector assignment.

► The pneumatic hoses need to be shortened to the optimum length, with the help of the gauge. See

also "3.3.1.7.2 Preparing the Trailing Cable" [ ➙ 37]. They must engage firmly but should not be fold

ed over.

► Loosely screw in the clamps (8) and (9).

► Check that the power track chain can run along the top of the machine base without obstruction.

Move the Y axis back and forth to check this.

► If necessary, correct at the trailing cable console (7) and at the clamps (8) and (9).

CAUTION

Handling

Handle the new trailing cable with care and enlist the help of a second person.

Make sure that the flat ribbon cable and the pneumatic hoses are not rubbed against any parts

or folded. Look out for sharp edges.

1. Complete trailing cable unit

2. Mount

3. Pneumatic hoses (shorten to optimum length with

gauge)

4. Gantry interface bracket

5. Gantry interface

6. Connection piece for cooling tubes to Y motor

7. Trailing cable console

8. Clamp at back of gantry

9. X trailing cable clamp

► Loosely fasten the trailing cable console (7) with a

screw.

► Clean the trailing cable contact surface on the ma

chine base with a dry cloth.

► Starting from the trailing cable console (7), run all ca

bles and hoses to the appropriate connections:

► Reconnect all electrical connections at the head

board. Observe the correct connector assignment.

► Reestablish all connections to the hotlink card and

the Vision board spread spectrum.
