Å First, adjust the following parts from the retrofitting kit to the substrate size that will be pro-
cessed afterwards, as described in Section 2.4.9:
– Centering unit (slide unit, X-direction)
– Thrust-piece holder
– "Guide rail, RH, assembly"
Å Using 4 countersunk screws M2 x 6, mount the Y-centering unit which consists of the clamping
element with rocker and thrust- piece holder (preassembled) on the rectangular cutout on the
movable conveyor side (see Fig. 2.4.2 -> 3, 4, 5, 6 ).
Å Exchange the compression spring(s) of the pertinent holddown (see Fig. 2.4.1 -> 7), if this is/
they are less than 32 mm long when not subjected to load -> item no. of the compression
spring: see Section 2.3.2.
Å In the reverse order to that described for removal in Section 2.4.3, install the pertinent hold-
down from the retrofitting kit, including the (if necessary, new) compression spring with retain-
ing bracket (support).
Key to Fig. 2.4.2 (RH):
A) Cable proximity switch -> to conversion PCB for PCB conveyor
B) Pneumatic hose -> to the solenoid valve on the back of the compressed air unit

This is installed instead of ball bearing when the substrates are only centered in the Y-direction.
It is fastened to the thrust-piece holder with 2 countersunk screws M3 x 6 (from the bottom)
each with 2 hex nuts.

NOTE:
Do not screw the following substrate guide elements (roller rails) completely tight yet as the align-
ment of the roller rails will have to be adjusted in a later step.

Å Install the (substrate) "Guide, short" and the (substrate) rail on the movable conveyor side (see
Fig. 2.4.3 -> 7, 8, 9):
-> Use the 2 socket hex head cap screws M3 x 8 previously removed to do so.
Å Install the (substrate) "Guide rail, RH" on the stationary conveyor side (see Fig. 2.4.3):
-> Use the 4 socket hex head cap screws M3 x 8 previously removed.
NOTE:
The 2 connecting rails included in the retrofit kit for the holddowns are not installed because they
are only required for reinstallation on the PCB centering unit (see Section 2.5).
Retain all of the parts not currently used as well as the 2 connecting rails, PCB guide rails and
disassembled ball bearings with shaft and screws so that they will be available for reinstallation
on the PCB conveyor or in case of a change in the substrate size.
