Proximity sensor “S4” not
reading– Small rounding
cup
o Sensor “S4” broken - replace it;
o Sensor "S4" disconnected from the connector - unscrew
and re-tighten the connecting ring nut;
o Sensor "S4" unscrewed from its seat - Screw it back up
to a distance of 0.5 ÷ 1 mm from the reading references;
o In manual work mode (par. 6.2.7), select page “H” and
press “START” for 10 seconds: the cup conveyor (Figure 1 ref. 6)
must be moving; if not, the “M3” motor is blocked - check for any
obstruction to the movement;
o Check the connection present in board “A1” to wire
number “704” of terminal board “M7”;
o Board “A1” may be faulty;
o Proximity sensor
“S5” not reading– Star
dosing devices stopped;
o "KV1" not
working - probable
breakage.
o Sensor “S5” broken - replace it;
o Sensor "S5" disconnected from the connector - unscrew
and re-tighten the connecting ring nut;
o Sensor "S5" unscrewed from its seat - Screw it back up

o Check the connection present in board “A1” to wire
number “705” of terminal board “M7”;
o Board “A1” may be faulty;
o Check that the cam placed near “S5” is well fixed on the
rotation axis, and if necessary lock it in position. During the work
cycle, the star dosing units must stop with the lower vertex
vertical with respect to its own work axis;
o Replace “KV1”.
Proximity sensor “S6” not
reading– The dough
compression piston has
reached the end of its
travel
o Sensor “S6” broken - replace it;
o Sensor "S6" disconnected from the connector - unscrew
and re-tighten the connecting ring nut;
o Sensor "S" unscrewed from its seat - Screw it back up to
a distance of 0.1 ÷ 0.3 mm from the internal profile of the dough
compression chamber.
o Failed insertion of dough compression piston (Figure 37
Pos. 6) in its working seat - Check the presence of the piston;
check that the metal pin connecting the piston is inserted all the
way in its seat; check that the plastic piston can slide along its
entire travel distance, up to the cylindrical dividing drum placed
on the left end;
o Hydraulic piston drive unit off or unable to function; no oil
