ACTS See Auto-compensated Top Stop.
actuation A change in the state or condition of a sensor.
actuation angle See dwell.
actuation block A graphical indicator on the Sensor Status screen in Run mode,
showing whether a sensor is actuated.
ANSI Stands for American National Standards Institute, a U.S.
clearinghouse and coordinating body for voluntary standards
activity on the national level.
auto advance A ProCamPAC feature that allows cam channels to be
programmed for speed-sensitive functions (e.g., feed advance,
pilot release, etc.) on variable speed presses. A channel
programmed as Auto Advance automatically advances cam
timing as the speed of the press increases and delays timing as
speed decreases. The rate of advance or delay is controlled by an
advance constant, a specified number of degrees of advance for
each 100 SPM increase in press speed.
auto carry-up A signal that causes the press to automatically complete the
stroke, stopping at TDC, when the operator releases his hands
from the palm buttons after the Auto Carry-up Angle has been
reached. Also called “Operator Station mute.”
auto carry-up angle The crank angle at which the pinch point has closed to less than
1/4 in. (6 mm), an opening determined by OSHA to be too small
to pose a hazard to the operator.
auto enable by sensor A die protection mode in which an individual sensor is
automatically actuated after a specified number of strokes.
auto enable by tool A die protection mode in which all sensors in a tool are
automatically actuated after a specified number of strokes.
Auto-compensated Top
Stop (ACTS)
A WPC 2000 feature, designed specifically for variable-speed
presses, that adjusts the top-stop angle automatically as press
speed changes or the brake wears.
