10 Glossary
The following terms are used in this manual. Where possible, definitions are from the U.S. and international product performance
standards that govern the design of the Banner device. For more definitions, visit www.bannerengineering.com.
ANSI (American National Standards Institute)
Acronym for the American National Standards Institute, an association of
industry representatives that develops technical standards (including
safety standards). These standards comprise a consensus from a variety
of industries on good practice and design. ANSI standards relevant to
application of safety products include the ANSI B11 Series, and ANSI/RIA
R15.06. See
Standards and Regulations
CE
Abbreviation for "Conformité Européenne" (French translation of
"European Conformity"). The CE mark on a product or machine
establishes its compliance with all relevant European Union (EU)
Directives and the associated safety standards.
Change of State (COS)
The change of an input signal when it switches from Run-to-Stop or Stop-
to-Run state. Dual-channel input signals, have two possible configurable
COS settings describe the signal disparity limits that can exist between
channels before a fault condition is registered: simultaneous and
concurrent. If simultaneity is a requirement or a concern for the
application, the user has to ensure that he made the right selection
during configuration.
Closed-Open Debounce Time
The time it takes to bridge a jittery input signal or bouncing of the input
contacts to prevent nuisance tripping of the Controller. Adjustable from 6
ms to 100 ms. The default value is 6 ms (50 ms for mute sensors). A
longer closed-open debounce time will also affect and increase the
response time of the system and/or the machine response time.
Code Validation
The configuration code file inspection process automatically performed
by the Controller to verify that the configuration code has not been
corrupted or altered in any way.
Commissioning
The process of operationally checking a Safety Controller installation on a
working machine, in order to verify that the control system is working
properly.
Defined Area
The "screen of light" generated by a safety light screen system, defined
by the height and the safety distance (minimum distance) of the emitter
and receiver. When the defined area is interrupted by an opaque object
of a specified cross section, a Trip or Latch condition results.
Designated Person
A person or persons identified and designated in writing, by the
employer, as being appropriately trained and qualified to perform a
specified checkout procedure.

A
Automatic Reset
The safety input device control operation setting where the assigned
safety output will automatically turn on when all of its associated input
devices are in the Run state. No manual reset operation is required for
the safety output to turn on when controlled only by safety input devices
configured for Automatic Reset. When Automatic Reset is selected, the
input device may be said to be configured to run in Trip mode.
C
Complementary Contacts
Two sets of contacts which are always in opposite states.
Concurrent
The setting that permits an indefinite signal disparity between channels,
without going into a fault condition. A fault condition is created if the
Stop signal changes back to a Run signal before its allied signal changes
to the Stop state. Both signals must change from the STOP state to the
RUN state before the dual-channel device is considered to be in the RUN
state.
Configurable
Describes a control device that has pre-defined and pre-tested
operational parameters that can be selected or enabled, in order to
accommodate a variety of control application requirements.
Configuration
A selected set of pre-defined and pre-tested input and output device
properties and logic relationships that define the operating algorithm
that the Safety Controller uses to control hazardous machine motion.
Confirmation
The two-step process where a new or modified configuration is sent to a
Controller for code validation, and a copy of the validated code is sent
back from the Controller to the PCI for manual parameter (I/O and
System settings) verification.
D
Diverse-Redundancy
The practice of using components, circuitry or operation of different
designs, architectures or functions to achieve redundancy and to reduce
the possibility of common mode failures.
Dual-Channel
Having redundant signal lines for each safety input or safety output.
