DANGER
Observe User Manual
► Please observe the safety instructions in the user manual for all work!
CAUTION
Use the correct blanking plugs
► Only use blanking plugs in the machine which match the manufacturer's compressed
air connection. A tight fit cannot be guaranteed for other blanking plugs.
► We recommend the use of blanking plugs made by Festo.

6.2 Replacing the Gantry
DANGER
Danger of crushing
The attraction force of the magnets is 400Nm.
CAUTION
Do not loosen or remove the screws
The loosening and removing of the fastening screws leads to tension. This has a negative
effect on the product life.

6.3.1 Replacing the X axis incremental encoder
Parts, equipment and tools
●
Select the correct incremental encoder:
Machine Incremental encoder (read head)
SIPLACE X4i S, X4 S, X3 S, X2 S MS22/25 X axis [03094995‑xx]
SIPLACE X4i S micron, X4 S micron MS30 X axis [03102066‑xx]
●
For MS22/25 incremental encoder: test device PG1-I [03102699‑xx]
●
For MS20/30/35 incremental encoder: test device PG-U [03071361‑xx] from FS02 (see also
technical information "Checking the track signals at the X and Y axes" [DE:TI2019‑02D04]
[EN:TI2019‑02E04])
●
Sealing varnish Loctite 241 [02101037-xx]
●
Ethanol
Isopropanol – IPA can be used as an alternative.
●
Stepladder, if required

Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.

NOTICE
Recommendation
► We recommend that you always perform the following tasks from the opposite side,
over the other gantry. You may need to use a stepladder or something similar to help
you.

► Unplug the incremental encoder cable from the head interface. In this case make a note of the
position to make clear assignment easier later on.
► Unthread the connection cable as far as the incremental encoder (2).
► Remove the three screws (3) fastening the incremental encoder (2) of the X axis and carefully
remove the incremental encoder.

Fig.182: Fitting the incremental encoder
► Clean the reading surface of the incre-
mental encoder with a cloth and eth-
anol or with a cleansing tip.
► Loosely fasten the incremental encoder
(2) with three fastening screws (3).
► The incremental encoder must be
aligned with a gap of 0.4mm (golden
scale) or 0.75mm (black-white scale)
to the scale. Use the corresponding
thickness gauge (plastic).
