Components located in the positioning range of the slide guide of the ceramic substrate centering
unit may result in incorrect centering or to an error message and stoppage of the placement pro-
cess -> Proximity switch signal for "Centering unit open" is not actuated.
Å Thoroughly vacuum off the slide guide in the front area (see Fig. 2.4 - 1 -> Pos. 3) and in the
area of the end stop, at back (see Pos. 1).
Å Remove the jammed component with tweezers.
Å Push the slide of the centering unit (see Pos. 2) all the way against the back stop and thor-
oughly vacuum off the portion of the slide guide that is now exposed at the front.
Å The make certain that the slide moves smoothly.
Å It must be possible to open the centering unit entirely (as far as the stop on the back) and to
close it entirely.
If you note a problem with the tension spring during this process, resume with the work in Sec-
tion 1.

Å Check to see if there is any damage to the surface (contact area of substrate) of the stationary
roller of the fixed stop (see Fig. 2.4 - 1 -> Pos. 4).
Å If there is an error, unscrew the screw fastening the roller (1 cross-slotted screw M3 x 8 DIN
965).
Å If the circumference of the roller is still in satisfactory condition, turn the roller,
until the satisfactory surface is pointing toward the substrate, then tighten the cross-slotted
screw M3 x 8 to fasten the roller.
Å If the roller no longer has a satisfactory surface, use the cross-slotted screw M3 x 8 to fasten
the new roller ,Item no. 00347284-01, in place.

If the tension spring on the flat cylinder of the mechanical ceramic substrate centering unit is faulty
or is mounted incorrectly, this may result in an error message accompanied by the stoppage of the
placement run -> Proximity switch signal for "Centering unit open" is not issued.
Å Check whether the open ceramic substrate centering unit is still being held securely at the end
stop (= maximum "open" position) by the tension spring (see Fig. 2.4 - 1 -> Pos. 5).
Å If applicable, suspend both ends of the spring correctly or, if the tension spring is damaged,
install a new one as follows:
Å Use the Seeger circlip pliers to remove the grip ring (see Fig. 2.4 - 1 -> Pos. 6) from the
spring suspension pin.
Å Unhook the faulty spring at both ends.
Å Suspend the new tension spring, Item no. 00359769-01 from both ends and install the cir-
clip (new, if applicable), Item no. 00048315-01 on the spring suspension pin.
