●
The upper and lower limits of the output bin are detected by three area sensors (PS981, PS982,
and PS983) on the output-bin-1- and output-bin-2-shift area sensor PCA.
●
The stacker controller PCA stops driving the output-bin-1-shift motor (M107) and output-bin-2-
shift motor (M108) when it detects the upper or lower limit of the output bin. Also, the on/off
combinations of the area sensors (PS981, PS982, PS983) are used to detect over-stacking
according to the stack height for large-size and mixed stacking.
●
The stacker controller PCA stops supplying +24 Vdc to the output-bin-1-shift motor (M107) and
stops the stacker operation when the output-bin-1 switch (MSW103) turns on.
