Replacing the X Axis Scale [03003745-xx]
Please also observe the technical information "Overview of Scales and Read Heads" [DE: TI2014-
05D11] [EN: TI2014-05E11].
Special equipment
▪ Scriber to loosen the scale
▪ Ethanol
▪ Protective gloves
▪ Double-sided adhesive strip - Scotch Y-9460 [00343774-xx]
▪ Protective sheet 12mm wide [00378511-xx]
Overview
► Fit the magnetic strip (1).
► Make sure that there is a gap of 0.8 mm between the
two magnetic strips.
► Install the blue covers.
► Install the cover plate for the magnet.
► Install the trailing cable.
► Install the PCB camera.
► Reconnect to the electrical and pneumatic systems.
► Fasten all electrical leads and pneumatic hoses to the
correct points.
► Install all dismantled modules, covers and cover
plates.
1. Head plate
2. X axis scale (fixed with adhesive)
3. Permanent magnets
4. X axis incremental encoder
► Move the head plate (2) to a suitable position so that
you can easily access the X axis scale (1) from all
sides.
WARNING!
STRONG MAGNETIC FIELDS!
Always follow the special safety instructions when work
-
ing in the vicinity of powerful magnetic fields, caused by
the permanent magnets (3).
CAUTION!
Do not dismantle the head plate!
To guarantee accuracy, make sure that you do not dis
-
mantle the head plate (2).
► Dismantle the incremental encoder (4).

Removing the incremental encoder
Removing the scale
► Place the new scale on a clean work surface.
► Attach the double-sided adhesive tape to the back of the new scale. The surface to be fixed down
must be clean and free of grease.
1. Head plate - front view
2. Incremental encoder
3. 3 x fastening screws
► Loosen the three screws (3) fastening the incremen
-
tal encoder (2) of the X axis and carefully lift off the
incremental encoder.
► Temporarily fasten the incremental encoder in a suit
-
able position.

► Mark the original position (1) of the scale (2) with a
scribing iron. This ensures that the new scale can be
fixed in the exact position to the right and left end
stop.
CAUTION!
Do not damage the gantry.
Make sure that the gantry coating is not damaged.
► Carefully lever the scale upwards on one side with
the scriber and then gently extract the scale.
► Remove any adhesive residues with ethanol. The
surface to be fixed down must be clean and free of
grease.

Service Manual (internal version) SIPLACE HF and X Series 53
Installing the scale
► Insert the new scale behind the head plate.
► Attach the new scale exactly to the lay-on edge on the gantry.
► Pull part of the cover strip off the adhesive strip and place the front end of the scale on the marked
position. The scale must be positioned at the lay-on edge.
► Now pull away the cover strip "bit by bit" and firmly fix the scale (to about halfway along the gantry).
► Move the head plate so that you can fix the rest of the scale.
► Press the scale down with a soft, clean cloth.
► Carefully pull off the cover strip.
► Use ethanol to wipe the scale and remove any adhesive residues or dirt.
► Fit the incremental encoder. This procedure is described in Chapter "Replacing the X Axis Incremen
-
tal Encoder".
