Removal
► Disconnect the cooling tubes (4) from the Y motor.
► 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).

3.5.5 Replacing the Trailing Cable Gantries
Service Manual SIPLACE SX4/DX4 83
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). You will need a "white Edding paint marker pen"
for this.
► Disconnect the cooling tubes for the Y motor from the
connection piece (4) (machine base).
CAUTION
Before cutting the pneumatic hoses
► Label the order of pneumatic hoses as shown on the gauge (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.
► Loosen the outer 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
"Vacuum pump SX4/DX4 assembly instructions"
[00196845-xx].
► Secure the end of the trailing cable (with cable ties) in
the machine to prevent it hanging loosely and damag-
ing other machine components.

► Remove the hoses from the pneumatic distributor (7).
► Undo the 4 screws (6) fastening the trailing cable console and carefully remove the complete trailing
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.
Gantry (using example of X series)
► Disconnect the flat ribbon cable (1) from the head
board (2).
► Disconnect the camera cable (3) from the head board
(2).
► Undo the outer 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].
