Chapter1General DescriptionGuardmaster TLSZ GuardLocking Switch OverviewThis Guardmaster TLSZ guard locking switch functions by locking itactuator, which prohibits the opening of a guard.The TLSZ guard locking switch uses radio frequency identification, RFID,coding to detect the appropriate target.This version of the Guardmaster TLSZ guard locking switch features OSSDoutputs. These outputs are enabled only when the actuator is locked and the RFtarget is sensed.This device is intended to be part of the safety-related control system of amachine. Perform a risk assessment before installation to determine whetherthe specifications of this device are suitable for all operational andenvironmental characteristics of the machine. See Specifications on page 49for certification information and ratings.Use nonremovable screws, bolts, or nuts to mount the switch and actuators.Do not over torque the mounting hardware.TLSZ guard locking switches are classified according to ISO 14119 as Type 4switching devices. The RFID targets are classified as having a high level ofcoding.Take measures to minimize the need to defeat and to manage the use andavailability of spare RFID targets.Catalog NumberExplanation440aCode440CodeZCodePTG bTcZdS21eUfbDescriptionGuard locking switchPgRhHiaDescriptionSafeguards the productCodeGdLock TypeDescriptionPLe rated, cascadablesafety signalseConnection TypeCodeDescriptionSolid-stateoutputs, 2S21safety (OSSD), 1 auxfSpecial FeaturesCodeDescriptiongLock TypeDescriptionAux signal shows lockstatusAux signal shows doorstatushConnection TypeCodeDescriptioniSpecial FeaturesCodeDescriptionRPower to ReleaseLPower to LockRockwell Automation Publication 440G-UM002C-EN-P - June 2022CodeTUHcDescriptionTitan locking switchUnique coded RFID target8-pin M12 QD connector7
Chapter 1General DescriptionATTENTION: Guard locking switches that use the Power to Lock principle canonly be used after a risk assessment shows that the Power to Releaseprinciple is inappropriate for the application. If a power supply loss occurswith Power to Lock switches, the switches immediately unlock and you canaccess the hazards.Packaging ContentsFigure 1 shows the contents in the shipping package.

Chapter2InstallationGeneral ConsiderationsThe TLSZ guard locking switch is designed for use on guards that areengineered to be rigid and without sag. The TLSZ guard locking switch usesradio frequency identification (RFID) coding to detect the appropriate target.Actuator/Target MountingFigure 2 shows the correct and incorrect ways to mount the target with theactuator.The TLSZ guard locking switch must only be used with the fully flexibleactuator. The replacement part number for the actuator is catalog number440G-A27143.Figure 2 - Target/Actuator MountingTargetActuator Allowable ApproachDirections The actuator and target must be always mounted as “close coupled” and canapproach the switch in any of the three entry slot positions that are shown inFigure 3. Approach from the underside is not allowed, as the distance from thetarget to the internal RF sensor is too far for proper operation.Figure 3 - Allowable Approach DirectionThis approach requiresguide repositioning, seepage 11.Rockwell Automation Publication 440G-UM002C-EN-P - June 20229
Chapter 2InstallationMinimum Operating RadiusFigure 4 shows the minimum operating distances along the length andperpendicular when applied to hinged doors.Figure 4 - Minimum Operating Distance [mm (in.)]80 (3.19)80 (3.19)80 (3.19)80 (3.19)Figure 5 shows the location of the two 1.5 mm (0.06 in.) set screws that can beadjusted to preset the actuator to an optimal angle, if needed.Figure 5 - Actuator Set Screw1.5 mm (0.06 in.)Manual ReleaseThe manual release feature only applies to TLSZR (Power to Release) switch. Insome cases, you must manually release the locked actuator.Figure 6 shows the two locations from which the actuator can be manuallyreleased.1. Remove the T20 Torx screw.2. To release the actuator, insert a small screwdriver or rod in the hole.If power is applied to the switch when the actuator is released, the OSSD safetyoutputs turn off and the switch goes to a faulted state with the status indicatorflashing red at 4 Hz. Power then must be cycled to the switch to return it to anoperational state.Figure 6 - Manual Release31T2022 2.5 (0.10) Ø10Rockwell Automation Publication 440G-UM002C-EN-P - June 2022
Chapter 2Manual Override CoverInstallationFigure 7 shows an optional cover that is available only for the TLSZR (Power toRelease) switch. This cover has a lever that allows you to unlock the actuatormanually at any time. Rotate the lever 90 to unlock the actuator.If power is applied to the switch when the actuator is released, the OSSD safetyoutputs turn off, and the switch goes to a faulted state with the status indicatorflashing red at 4 Hz. Power is then cycled to the switch to return it to anoperational state.Figure 7 - Manual Override Cover121.2 N m (10.62 lb in)90 90 Pair ProximityIf a pair of TLSZ guard locking switches are mounted too close to each other,the two RF fields could interact causing crosstalk. Cross talk results innuisance faults.A minimum of 200 mm (8 in.) must be used to help achieve correct operation.The restriction also applies if a TLSZ guard locking switch is mounted close tothe 440G-LZ guard locking and the 440N-Z SensaGuard switches.Guide RepositioningThe actuator guide can be repositioned to facilitate alignment of the actuator.In steps 8 11 (Figure 8), rotate the metal guide to allow the switch body to befastened flush to the mounting surface.Figure 8 - Guide Repositioning27315648180 10119Rockwell Automation Publication 440G-UM002C-EN-P - June 202211
Chapter 2InstallationSteel Locking BoltsThe TLSZ guard locking switch is assembled in the factory with plastic pinsthat secure the actuator guide. The plastic pins are rated for a holding force of1500 N (337 lb). The plastic pins must be replaced with the steel bolts to achievea holding force of 2000 N (585 lb). Figure 9 shows how to remove the cover toreplace the blue plastic pins with steel bolts.Figure 9 - Steel Bolt Installation1.2 N m (10.62 lb in.)5 (0.20)dia.15 (0.59)2 x M51.4 N m(12.39 lb in.)1.2 N m (10.62 lb in.)2 x M51.4 N m (12.39 lb in.)Plastic pinsFzh 1500 N (337 lb)Actuator ClearanceSteel boltsFzh 2000 N (450 lb)Figure 10 shows the clearance requirements for the TLSZ guard locking switch.The switch must not be used as a guard stop. You must provide a mechanicalstop at least 1 mm (0.04 in.) away from the actuator guide. The actuator mustbe inserted within 4 mm (0.16 in.) or less from the actuator guide to be sure itlocks.Figure 10 - Clearance and Insertion Distance1 41 4(0.04 0.16)(0.04 0.16)As shown in Figure 11 on page 13, the TLSZ guard locking switch has twoslotted holes to facilitate installation. The slots allow up to 8 mm (0.31 in.) ofmovement of the switch body to achieve the proper clearance with theactuator.1. Use the slotted holes for initial installation.2. After alignment with the actuator, secure the switch body in place byadding mounting hardware in the circular holes.12Rockwell Automation Publication 440G-UM002C-EN-P - June 2022

The OSSD inputs allow the TLSZ guardlocking switches to be connected in-series while maintaining a high level ofsafety performance.OSSD OutputsThe OSSD outputs are Safety A and Safety B. These outputs are 24V signalsthat contain test pulses. The test pulses are used to detect short circuits to 24V,to 0V and cross faults (from Safety A to Safety B). This description of the testpulses is provided for informational purposes; you cannot modify them.Figure 15 on page 16 shows the safety output test pulses when connected to a 1Kresistive load for hardware (HW) revisions A and B, and for firmware (FW)revisions A through C. The pulses are 25 μs wide and repeat every 20 ms. Theexact shape of the pulses depends on the nature of the load. The capacitive andresistive effects of the load are determined with the combination of cabling,cable routing, and connected devices.Rockwell Automation Publication 440G-UM002C-EN-P - June 202215

The auxiliary output is a 24V DClogic signal, whose function is dependent on the catalog number selected. Theauxiliary signal responds independently of the OSSD safety outputs. Theauxiliary output is not a safety-rated signal and must only be used to indicatethe status of the switch.Table 3 - Auxiliary Output FunctionCat.

The lock command is a 24V logicsignal, with a current of less than 5 mA. The function of the logic signal isdependent on the catalog number. The 24V power supply connection providesthe power to operate the locking solenoid.Table 4 - Lock Command FunctionCat.

Chapter4CommissioningBefore use, the guard locking switch must first learn a new RFID target. Thisstep is not done at the factory.The guard locking switch can learn up to eight targets consecutively. Use thisprocess if there is a potential for the target to become damaged, inoperable, orlost. When a new target is learned, the guard locking switch no longerrecognizes the old target.PreparationWire the guard locking switch with at minimum the functionality shown inFigure 16. Power — connect the brown wire to 24V. Gnd — connect the blue wire to 0V. Lock — Leave the green wire open when learning the first target.Connect the green wire to 24V to teach a TLSZR guard locking switchsubsequent targets. The TLSZL guard locking switch ignores the Lockcommand during learning. Safety A and Safety B — connect red and yellow wires to 24V duringcommissioning. If 24V is not applied to the A and B inputs, then theindicator flashes green after commissioning if the guard locking switchis locked. Safety A and Safety B — optional, no connection required forcommissioning. Aux — optional, no connection required for commissioning.Figure 16 - Commissioning Wiring 24V DCTLSZ-GD2Status Diag889D-F8NB-xor889D-F8AB-xBrown ( 24)Red (OSSD A )Yellow (OSSD B )Green (Lock)Gray (OSSD A)Pink (OSSD B)White (Aux)Blue (Gnd)Rockwell Automation Publication 440G-UM002C-EN-P - June 2022LockNCNCNC24V DC Com17
Chapter 4CommissioningFirst Time Power-upTurn on the 24V DC power without the actuator and target.The Status/Diagnostic indicator blinks green three times, pauses 2 seconds,and then blinks green eight times. Eight is the number of times a new targetcan be learned. The guard locking switch continuously repeats the two-secondpause followed by the eight blink sequence.Learn First TargetTable 5 shows the events that take place when the first target is learned. Thelock command is ignored until after the guard locking switch learns its firsttarget, therefore, the lock command can be 24V or 0V during the first-timelearning sequence.Table 5 - First Target Learning EventsStep123456789Learn Additional TargetsEventApply power to guard locking switchPresent actuator/targetDetect targetVerifying targetReport commissioning error (seeTable 7 on page 19) or continueProgramming switchFinalizingNumber of learns remainingLearn completedPTRPTLIndicator ColorRedRedRedGreen/RedBlink RateSolidSolidSolid1 HzDuration——2 25 s15 s———Green/RedRedGreen4 HzSolid# of learns15 s2s15 sGreenRedSolidContinuousTable 6 shows the steps that take place when teaching the guard locking switchto recognize an
