G-2 Glossary
IBI Stands for Individual Beam Indicator, a red LED located next to each
phototransistor on the receiver. IBIs indicate beams that are
misaligned, beams that are interrupted during a light curtain
penetration, and the area occupied by a programmed blanking
fixture. IBIs on the Main Receiver also display fault codes.
LED Stands for light-emitting diode, a type of indicator whose state (i.e.,
lit or unlit) provides information about the status of the light curtain.
ninety-degree stop
time test A test required to set the proper safety distance for personnel-
guarding devices, including light curtains, two-hand controls, and
type-B movable barriers. This test checks the stopping time of the
press at its most critical stopping point, normally the midpoint of the
downstroke (i.e., 90°), while the press is running in Continuous
mode (or Single-stroke if the press does not have a selector setting
for Continuous). Stopping time is a value required in the ANSI
formula for calculating the safety distance.
object sensitivity A value required in deriving the depth penetration factor for a light
curtain. Object sensitivity specifies the smallest diameter object that
a light curtain can detect anywhere in its field.
OSHA Stands for Occupational Safety and Health Administration, a
government agency that has established regulations for mechanical
power presses, including presence-sensing devices for point-of-
operation guarding.
OSSD Stands for Output Signal Switching Device, a type of safety output.
Shadow 8 has two OSSD outputs that can be connected to the
guarded machine’s emergency stop circuit to stop the machine
whenever the light curtain is obstructed.
pinch point The hazardous area between the upper and lower die from which
OSHA mandates that the operator should be protected by installation
of safety equipment such as light curtains, two-hand controls, and
other barriers.
response time The time it takes a machine control to activate the machine’s brake.
safety distance The distance from the pinch point that OSHA requires safety
equipment such as light curtains, two-hand controls, and type-B
movable barriers to be installed to assure the safety of the operator.
The safety distance is calculated using a precise formula set by
OSHA regulations and/or ANSI standards.
