Part-Revolution Clutch
A type of clutch that may be engaged or disengaged during the machine cycle. Part-revolution clutched machines use a
clutch/brake mechanism, which can arrest machine motion at any point in the stroke or cycle.
Pass-Through Hazard
A pass-through hazard is associated with applications where personnel may pass through a safeguard (which issues a
stop command to remove the hazard), and then continues into the guarded area, such as in perimeter guarding. Subse-
quently, their presence is no longer detected, and the related danger becomes the unexpected start or restart of the ma-
chine while personnel are within the guarded area.
Point of Operation
The location of a machine where material or a workpiece is positioned and a machine function is performed upon it.
PSDI (Presence-Sensing Device Initiation)
An application in which a presence-sensing device is used to actually start the cycle of a machine. In a typical situation,
an operator manually positions a part in the machine for the operation. When the operator moves out of the danger area,
the presence sensing device starts the machine (no start switch is used). The machine cycle runs to completion, and the
operator can then insert a new part and start another cycle. The presence sensing device continually guards the ma-
chine. Single-break mode is used when the part is automatically ejected after the machine operation. Double-break mode
is used when the part is both inserted (to begin the operation) and removed (after the operation) by the operator. PSDI is
commonly confused with "Trip Initiate." PSDI is defined in OSHA CFR1910.217. Banner safety light curtain systems may
not be used as PSDI devices on mechanical power presses, per OSHA regulation 29 CFR 1910.217.
Q
Qualified Person
A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowl-
edge, training and experience, has successfully demonstrated the ability to solve problems relating to the subject matter
and work.
R
Receiver
The light-receiving component of a safety light curtain system, consisting of a row of synchronized phototransistors. The
receiver, together with the emitter (placed opposite), creates a "screen of light" called the defined area.
Reduced Resolution
A feature that allows a safety light curtain system to be configured to produce an intentionally disabled light beam(s) with-
in the light curtain, which increases the minimum object sensitivity. The disabled beam(s) appears to move up and down
(float) to allow the feeding of an object through the defined area at any point without tripping the safety outputs (for exam-
ple, OSSDs) and causing a Auto Start/Restart (Trip) or Manual Start/Restart (Latch) condition. Sometimes called Floating
Blanking.
Reset
The use of a manually operated switch to restore the safety outputs to the On state from a lockout or a Manual Start/
Restart (Latch) condition.
Resolution
See Minimum Object Sensitivity .
S
Self-Checking (Circuitry)
A circuit with the capability to electronically verify that all of its own critical circuit components, along with their redundant
backups, are operating properly. Banner safety light curtain systems and safety modules are self-checking.
Safety Distance
The minimum distance required to allow the machine’s hazardous motion to stop completely, before a hand (or other ob-
ject) can reach the nearest hazard point. Measured from the midpoint of the defined area to the nearest hazard point.
Factors that influence minimum separation distance include the machine stop time, the light curtain system response
time, and the light curtain minimum object detection size.
Specified Test Piece
An opaque object of sufficient size used to block a light beam to test the operation of a safety light curtain system. When
inserted into the defined area and placed in front of a beam, the test piece causes the outputs to de-energize.
