OverviewSLTSeriesIntroductionThe SLT Series system is a dual redundant digit alinfrared point of operation guarding device which willprovide a signal to stop the machine when there is entryinto the guarded area. The system uses invisible infraredlight to detect obstructions protruding through theguarded area. The use of infrared light provides anunobstructed view of the work area and also makes theSLT Series system insensitive to almost all ambient lightconditions.The dual redundant system basical ly incorporates twomic roprocessors, four watchdog timers , and twoseparate captive contact relays to assure fail-safeoperation. If either microprocessor detects a failure inthe system or the other microprocessor , the workingmicroprocessor can shut down the unit. The watchdogtimers assures that if the oscillator on eithermicroprocessor is not running correctly , they can shutthe system down. The special force-guided contactrelays* allow self-checking software to detect a faultyrelay and shut down the unit with the redundant relay .The Diagnostics Display allows the user to betterunderstand the current condition of the light curtain. If afault is discovered by the light curtain, it will be displayed.The display is also used when options like the FloatingBlank or Auto Blank are being used. A brief descriptionof each follows:The Floating Blank option allows work pieces(designated by dimensions) to move throughoutthe guarded area without shutting the machinedown but entry into the protected area by theoperator will still provide a signal to stop themachine. The Floating Blank option does not needto be adjusted for various positions or die heightchanges, only adjusted for the size of the workpiece. Up to three beams at a time are allowedto be obstructed when the Floating Blank optionis in use.The Auto Blank option allows work pieces or fixedobjects to penetrate the guarded area withoutshutting the machine down. The size and locationof the object(s) is automatically programmed intothe computer with a turn of a key, so you do notneed to know the size of the object to programthe unit. Auto Blank must be reprogrammed whenthere is a loss of power. Up to eight beams at atime are allowed to be obstructed when the AutoBlanking option is in use. Force-Guided Contact Relays are mechanically linked togethe rto force both poles to maintain the same position regardless ofwhether the relay is energized or de-energized. This allows awelded contact to be detected by monitoring the other pole.The SLT Series system operates from two pylons. Powermust be supplied separately to both pylons usingstandard wiring procedures. The interface or stop circuitinterconnection is made from the Receiver Pylon.The SL T Series system can only be used on p artrevolution or clutched machines which can be signaledto stop at any part of their cycle by opening an electricalcircuit.Theory of OperationThe SLT Series system is an infrared light curt ainconsisting of two pylons that talk to each other via aninfrared channel called the Sync Channel. The ReceiverPylon transmits to the Emitter Pylon for the purpose ofsynchronizing the two units eliminating the need for athird box with a cable connecting the pylons together .The status of the Sync Channel can be determined bythe Diagnostics Display on the Receiver Pylon whichwill show flashing decimal points to indicate that theEmitter Pylon is not firing.The Receiver Pylon is the controller and the EmitterPylon is slaved to it by the Sync Channel. The internallogic of the Receiver Pylon controls the scanningfunction, the detection, the output control, and theinternal diagnostic functions.When the two pylons are synchronized, the Emitter Pylonbegins to scan from the top down with its infraredemitters called "data channels" or otherwise known asinfrared beams. The Emitter Pylon's beams are scannedmany thousands of times a second and, each time abeam is selected, its infrared emitter is pulsed. Thissequential scan of infrared pulses is picked up by theReceiver Pylon which is synchronized to the scanningEmitter Pylon and recorded. If a beam is blocked by anobstruction, the control logic drops out the Output Relaysand turns on the RED indicator.The Internal Diagnostic Logic runs at the same frequencyas the scan frequency so all operational componentsand timings are checked many thousands of times asecond to insure Fail-Safe operation. The control logicin this unit has no lock-up or failed mode except for hardinternal failures. No matter what conditions prevail, theunit is trying to keep all systems operational.
