Glossary GL-3
crank angle clock A graphical indicator on the SmartPAC 2 display that shows the
angle of rotation of the press’s crankshaft.
critical angle The point in the crankshaft rotation after which a stop signal to
the press cannot prevent the die from closing.
depth penetration factor A value used in the ANSI formula for calculating the
safety
distance
. The depth penetration factor is a measure of how far an
object, like an operator’s hand, can move through the light
curtain before the light curtain reacts.
diode A component that reduces or eliminates electrical noise.
dual diverse redundancy A WPC 2000 feature in which both microprocessor systems
belong to different architectures, are programmed using different
programming languages, function independently of one other,
have separate power supplies, and provide different information
to the operator. Dual diverse redundancy provides optimum
clutch/brake control and operator safety.
Dual Safety Valve The control-reliable device on the press that controls the flow of
air to the press’s clutch.
dwell The range of angles during which a sensor or cam is actuated, or
“on.” Also called
actuation angle
.
emergency stop A signal sent to the press in response to a malfunction that stops
the press immediately.
fault (error) messages Messages appearing on the SmartPAC 2 LCD that indicate a fault
condition.
hand-speed constant A value used in the ANSI formula for calculating the
safety
distance
. The hand-speed constant is the distance one can
theoretically move one’s hand and arm in one second. OSHA
recommends a hand-speed constant of 63 inches-per-second.
interrupted stroke A condition that occurs when the press has been Emergency-
stopped before the completion of the stroke by either the operator
or an automatic device for personnel or equipment protection.
During an interrupted stroke condition, the message “Interrupted
Stroke” flashes in the status box at the top of the SmartPAC 2
screen.
