X Loosen the three screws on the bracket (1)

and carefully lift off the incremental encoder

X Temporarily fix the incremental encoder to a

suitable place (e.g. with adhesive tape or a

cable tie to the back of the gantry). Make sure

that the gantry can still be moved along the Y

Installation

X Place the new scale on a clean work surface.

X Attach the cover strip to the front side of the scale.

X 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.

X Always move the gantries to the position which gives you the best access to the current working

area.

X Place the scale under the gantries in the machine.

X Pull the transparent cover strip back until you can see the drilling on the scale and have enough room

to feed in the adhesive device. Start from the left side (when viewed in the direction of transport).

4-6: Threading the scale into the adhesive device (cross-section from above)

Legend

X Thread the scale, with its cover strip and adhesive strip, into the adhesive device. To do this, pull the

protective cover on the adhesive strip partly off the scale and wind it around the fixing pin (see

diagram).

NOTE: Cover strip on scale

X There is now a cover strip protecting the front of the scale. Only remove this cover strip during

installation (not before).

To move past a gantry during fixture, you will need to interrupt the procedure. Proceed as follows:

X Before starting work, you should pull the gantries as far as possible to the right.

X Extract the fixing pin from the adhesive device.

X Remove the adhesive device.

X Move the gantry to the left.

X Thread the scale back into the adhesive device.

X Continue fixing the scale.

X Press the last piece of the scale down with your hand and with the help of a tear-resistant cloth.

X You can now press the scale down again firmly, if required. To do this, slide the adhesive device over

the scale.

X Remove the centering pin.

X Clean the scale with a cloth and ethanol.

X Clean the reading surface of the incremental encoder with a cloth and ethanol or with a SIPLACE

cleaning tip.

X Fit the incremental encoder with the three fastening screws so that there is a gap of 0.4 mm between

the incremental encoder and the scale. Use a suitable thickness gauge (plastic).

X Check the track signals.

X Calibrate the machine zero point.

2. Complete adhesive device

3. Scale

Start fixture at the drilling (1), on the left side of the

machine.

X Fit the scale (3) onto the centering pin and

push this into the drilling. At the same time,

place the adhesive device (2) so that the scale

is fixed horizontally onto the adhesive surface.

X Move the adhesive device to the right. While

doing so, press the scale and the adhesive

device firmly against the adhesive surface.

Carefully pull off both strips, piece by piece,

from the scale.

ATTENTION: Make sure that no

blisters or uneven areas are formed.

If this does occur, the scale must be

removed and replaced with a new

scale.

NOTE:

Fasten the scale as far as possible in one go. This prevents unnecessary interruptions to the

fixture process.
