Replacing the X-Axis Incremental Encoder (Read Head) [03047215S-xx]
Overview
► Unplug the connection cable at the gantry head dis-
tributor and unthread it as far as the PCB camera (1).
Open the cable ties, where necessary.
► Loosen the four screws fastening the PCB camera
mount (2).
► Install the new PCB camera on the mount (2). Tighten
the screws and secure with loctite 241.
► Run the connection cable to the gantry head distribu-
tor and reconnect to the electrical system.

► Move the relevant changeover table out of the ma-
chine.
► Shut down the machine and switch it off.
► Unplug the incremental encoder (3) from the gantry
head distributor (1).

Installation
► Clean the reading surface of the incremental encoder
with a cloth and ethanol or with a Q-tip.
► Loosely fasten the incremental encoder (3) with the
screws (4).
► The incremental encoder must be aligned with a 0.4
mm gap to the scale. Use the corresponding thick-
ness gauge (plastic).
Casting marks on the incremental encoder (X-axis on X-
series machine shown as example)
► You must set the exact height to the scale.
► Align the incremental encoder, using the two casting
marks (arrows), which mark the read area.
