5 Adjustment of machine options
5.1 Automatic push-back blocking
The light beam of the photo cell (5) of the automatic
push-back blocking must hit the center of the reflecting
foil (1). This must be 70 mm away from the outer edge
of the table.
The distance between the setting ring (2) of the photo
cell (5) and the bearing shield (3) must be 10 mm. To
adjust it, loosen the fixing screw (4) and push the photo
cell together with the setting ring. Tighten the fixing screw.
To check whether the light beam hits the middle of the
reflecting foil (1) exactly, lay a piece of cloth or paper on
the table and push it from all directions over the reflec-
ting foil. As soon as the photo cell switches, the red di-
ode (6) turns dark. Move the photo cell by moving and
turning of the setting ring until the light beam is adjusted
exactly.
Hint
In the case of a breakdown of the push-back blocking
it can be disabled in the machine control (seam
parameter 36).
5.2 Height of the take off roller
Lower the take off roller (1) (output 23 in the machine
control).
Check whether the screw (2) has a free play of 1 mm. If
not, loosen the counter nut at the screw and move it
correspondingly.
Tighten the counter nut again.
