Automatic Operation
When the Selector Switch is set to "AUTO" the Material Return will
raise and lower automatically as the Ram moves through its cutting
cycle. The Air Cylinder holds the Material Return horizontally,
allowing the work material to rest on it, until the Prox Switch is
activated by the Actuation Flag. The solenoid on the air valve is
then turned on, causing the cylinder to retract, and rotating the
Material Return downward. The cut material is then directed into
the Material Chute.
The Material Return remains angled downward as the Ram moves
upward until the Actuation Flag is raised above the Prox Switch.
The solenoid on the air valve is then turned off, causing the Air
Cylinder to extend, and raising the Material Return back to its
horizontal position. Once the Ram has reached its top position, the
Material Return is ready to support the next piece to be cut.
The "AUTO" mode is designed for use with the Single and Jog
cutting modes of the shear. It is not recommended for use in
Continuous cycle cutting.
Fixed Operation
The position of the Material Return may be fixed in either the
horizontal position or angled downward. When the Selector Switch
is set to "DOWN" the Material Return is lowered downward until
the Air Cylinder is fully retracted. The Material Return remains
angled down at all times during the cutting cycle of the Ram.
When the Ram nears the bottom of its stroke, the Material Return
will rub against the nylon strip mounted on the rear angle connecting

The time to complete a cutting cycle in Continuous mode may not be sufficient for
N O T E
the Material Return to reach its top horizontal position before the next cutting cycle starts.
Keeping the Material Return set to "AUTO" under these conditions may yield unexpected
results.
