Glossary
checksum
A numeric value calculated when a tool is stored in memory and
when it is loaded. The two values must match or SmartPAC 2
displays a fault message.
crank angle clock
A graphical indicator on the SmartPAC 2 display that shows the
angle of rotation of the press’s crankshaft.
communications
Data sent by SmartPAC 2 to one of its installed options (e.g.,
WPC, SFI, etc.) or received from an installed option.
counter
A SmartPAC 2 feature that maintains a count of the number of
strokes made by the press, the number of good parts produced, or
the number of strokes that must occur before a programmed
output is actuated. See batch counter.
control reliability
A regulation defined in ANSI B11.1-2009 and OSHA 1910.217
requiring that a single component failure in a clutch/brake control
circuit not prevent the normal stopping action of the press, not
create an unintended stroke, and not allow initiation of a
subsequent stroke until the failure has been corrected.
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.
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.
error message
A message appearing on the SmartPAC 2 LCD that indicates a
fault condition, identifies the problem, and may suggest how to
correct it.
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.
manual enable
A die protection mode in which sensors are manually enabled or
disabled by the operator.
