a
Manual Start and subsequent entry of the transported material
in the muting area.
b
Muting mode active.
c
Transported material interrupts light curtain.
d
Transported material leaves the light curtain and muting area.
The exit of the transported material ends the muting mode.
e
The subsequent transported material tilts so that the status of
the second muting sensor A2 cannot follow the status change
of the muting sensor A1 within the synchronisation time ST. The
enable at LM01QS is removed and the error is signalled via
LM01ER.
f
Actuating the override key switch (LM01OV) enables the trans-
ported material to be moved through the light curtain. If the
default state is reached again (light curtain and muting sensors
clear), the enable at LS01QS is removed again as MST (Manual
Start) is set.
g
Actuating the Reset button causes the LM01RE coil to pick up
and restarts the LM01 function block. As the light curtain is not
interrupted and there is no error, the enable is issued via
LS01QS.
