10 GlossaryThe following terms are used in this manual. Where possible, definitions are from the U.S. and international productperformance standards that govern the design of the Banner device. For more definitions, visit Banner Website.AANSI (American National Standards Institute)Acronym for the American National Standards Institute, anassociation of industry representatives that develops technicalstandards (including safety standards). These standards comprisea consensus from a variety of industries on good practice anddesign. ANSI standards relevant to application of safety productsinclude the ANSI B11 Series, and ANSI/RIA R15.06. SeeStandards and Regulations on page 56.Automatic ResetThe safety input device control operation setting where theassigned safety output will automatically turn on when all of itsassociated input devices are in the Run state. No manual resetoperation is required for the safety output to turn on whencontrolled only by safety input devices configured for AutomaticReset. When Automatic Reset is selected, the input device may besaid to be configured to run in Trip mode.CCEAbbreviation for "Conformité Européenne" (French translation of"European Conformity"). The CE mark on a product or machineestablishes 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-Stopor Stop-to-Run state. Dual-channel input signals, have twopossible configurable COS settings describe the signal disparitylimits that can exist between channels before a fault condition isregistered: simultaneous and concurrent. If simultaneity is arequirement or a concern for the application, the user has toensure that he made the right selection during configuration.Closed-Open Debounce TimeThe time it takes to bridge a jittery input signal or bouncing of theinput contacts to prevent nuisance tripping of the Controller.Adjustable from 6 ms to 100 ms. The default value is 6 ms (50 msfor mute sensors). A longer closed-open debounce time will alsoaffect and increase the response time of the system and/or themachine response time.Code ValidationThe configuration code file inspection process automaticallyperformed by the Controller to verify that the configuration codehas not been corrupted or altered in any way.CommissioningThe process of operationally checking a Safety Controllerinstallation on a working machine, in order to verify that thecontrol system is working properly.Complementary ContactsTwo sets of contacts which are always in opposite states.ConcurrentThe setting that permits an indefinite signal disparity betweenchannels, without going into a fault condition. A fault condition iscreated if the Stop signal changes back to a Run signal before itsallied signal changes to the Stop state. Both signals must changefrom the STOP state to the RUN state before the dual-channeldevice is considered to be in the RUN state.ConfigurableDescribes a control device that has pre-defined and pre-testedoperational parameters that can be selected or enabled, in orderto accommodate a variety of control application requirements.ConfigurationA selected set of pre-defined and pre-tested input and outputdevice properties and logic relationships that define the operatingalgorithm that the Safety Controller uses to control hazardousmachine motion.ConfirmationThe two-step process where a new or modified configuration issent to a Controller for code validation, and a copy of thevalidated code is sent back from the Controller to the PCI formanual parameter (I/O and System settings) verification.DDefined AreaThe "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 interruptedby an opaque object of a specified cross section, a Trip or Latchcondition results.Designated PersonA person or persons identified and designated in writing, by theemployer, as being appropriately trained and qualified to performa specified checkout procedure.Diverse-RedundancyThe practice of using components, circuitry or operation ofdifferent designs, architectures or functions to achieveredundancy and to reduce the possibility of common modefailures.Dual-ChannelHaving redundant signal lines for each safety input or safetyoutput.EEmitterThe light-emitting component of a safety light screen system,consisting of a row of synchronized modulated LEDs. The emitter,together with the receiver (placed opposite), creates a "screen oflight" called the defined area.Enable a Mute Time LimitAs soon as a mute sensor is mapped to a safety input device, adefault time limit of 30s will show up in the properties window.This time limit can be disabled by unchecking the ‘Enable TimeLimit’ box. This extends the time for the mutable safety device tobe muted to infinite.External Device Monitoring (EDM)A means by which a safety device (such as a safety light screen)actively monitors the state (or status) of external devices thatmay be controlled by the safety device. A lockout of the safetydevice will result if an unsafe state is detected in the externaldevice. External device(s) may include, but are not limited to:MPCEs, captive contact relays/contactors, and safety modules.EZ-SCREEN® Type 2 Light ScreenPhone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
