• Up to PL e, SILCL 3, category 4Correct UseThe ESM-2H2.. 2-hand safety relay is an extremely compact, universal safety two-hand control unit. It complies with EN574, Typ III C, and is intended for use in safety circuits that are designed in accordance with EN 60204-1, e.g. on presses, punches and bending tools. Due to the internal error monitoring, the 2-hand safety relay can be used, despite very compact dimen-sions, for all applications up to the highest safety cate-gory 4 and PL e according to EN ISO 13849-1, SILCL 3 according to EN 62061 or Typ III C according to EN 574.Features• 2 safe, redundant relay outputs• Cyclical monitoring of the output contacts• Feedback loop for monitoring downstream contactors orexpansion modules• Short circuit and earth fault monitoring • Extrem compact housingFunctionThe EUCHNER 2-hand safety relay ESM-2H2.. is suitable for setting up and monitoring two-hand circuits and is used to protect the operators. Dangerous work steps can only be triggered when both two-hand buttons connected are ope-rated simultaneously, i.e. within 0.5 s.It is to be ensured a single fault or a malfunction does not result in the loss of the safety function and every fault is detected by the cyclic self-monitoring at the latest prior to the next actuation.When the operating voltage is applied to A1-A2 and the feedback loop X1-X2 is closed, the ESM-2H2.. is ready for use. To be able to initiate a switching operation, the output relays must be de-energized. The output relays only switch to the energized position when the two-hand buttons T1 and T2 are operated simultaneously, i.e. within 0.5s.Fig. 1 Block diagram ESM-2H2..InstallationAs per DIN EN 60204-1, the device is intended for installa-tion in control cabinets with a minimum degree of protection of IP54. It is mounted on a 35 mm DIN rail according to DIN EN 60715 TH35.Fig. 2 Installation/removalElectrical Connec-tion• When the 24 V version is used, a safety transformeraccording to EN 61558-2-6 or a power supply unit with electrical isolation from the mains must be connected. • External fusing of the safety contacts must be provided. •A maximum length of the control lines of 1000 meters with a line cross section of 0.75 mm 2 must not be excee-ded.•The line cross section must not exceed 2.5 mm2. •If the device does not function after commissioning, it must be returned to the manufacturer unopened. Ope-ning the device will void the warranty.A1: Power supply A2. Power supply S11: Control line T1 S12: Control line T1 S13: Control line T1 S21: Control line T2 S22: Control line T2 S23: Control line T2 X1; X2: Feedback loop 13-14: Safety contact 1 23-24:Safety contact 2The output relays are not switched if:• only one two-hand button is actuated or the time between the actuation of the 2 two-hand buttons is greater than 0.5 s, • the feedback loop is open (fault in the external contactor),• another error (short circuit, cable break, error in the switching device) has occurred.When T1 and/or T2 are/is released, the output relays opens immediately. In order to trigger a new operation, both two-hand buttons must first be released and the feedback loop must be closed.ESM-2H2..The arrangement of the two-hand buttons must be designed in accordance with the standard EN 574 such that accidental actuation or simple bypassing of the safety function is excluded.The ESM-2H2.. unit is provided for the connection of 2-hand push-buttons, with one normally open or one normally colsed contact.Figur 1 shows the wiring of the ESM-2H2.. with a 2-hand push-buttons:ApplicationsFig. 1:Wiring of the ESM-2H2.. with a 2-hand push -buttonsFig. 2: Feedback loopContactors connected to the ESM-2H2.. or the basic devices are monitored via the feedback loop of the basic device. K A and K B are the positively driven contacts of the connected contactor or expansion module.Feedback loopNote: The items listed under “Electrical connection” must be observed during commissioning. Commissioning Procedure1. Wiring ESM-2H2..:Wire the ESM-2H2.. With the 2-hand push button according to your application (see Fig. 1).2. Wiring feedback loop:Wire the feedback loop as shown in Fig. 2.3. Wiring power supply:Connect the power supply to terminals A1 and A2.Warning: Wiring only in de-energized state.4. Starting the device:Switch the operating voltage on.5. Switch to working condition:Press the two buttons T1 and T2 simultaneously, or within 0.5 seconds.The positive-guided relay switches.6. Switch into hibernation:Release the two buttons T1 and T2. The positive-guided relay swiches off.Jumper X1-X2: See descriptionX1 X2InstallationAvoiding unintentional actuation or bypassing of the safety deviceThe arrangement of the two-hand buttons must be designed in accordance with the standard EN 574 such that accidental actuation or simple bypassing of the safety function is excluded.The operation of both buttons using one hand must be prevented by an adequate distance (at least 260 mm) or by a sepa-rating wall. Actuation using forearm, elbow, knee, hip or other parts of the body can be effectively prevented by a further increase in the distance between the two buttons, adequate distance from the floor and/or covers and/or separating walls. Distance from the two-hand buttons to the danger areaIt is necessary to maintain a minimum distance between the buttons for the two-hand circuit and the danger area on themachine or plant so that, after the release of one or both buttons, the machine or plant can only be reached once the dange-rous movement has been interrupted or completed. According to the standard DIN EN ISO 13855, the distance is calculated with the following equation:S = (K · T) + CS : Minimum distance from the nearest pushbutton (two-hand button) to the danger area.K : Parameter in mm/s, derived from data on the approach speeds of the body or parts of the body, for two-hand circuits 1600 mm/s.T : The overtravel of the overall system in seconds, that is the time from releasing the two-hand button to the end of the dan gerous movement.C : Additional distance in mm that based on entry into the danger area prior to the triggering of the safety device. For twohand circuits this is 250 mm, this distance can also be set to 0 mm given an adequate cover on the buttons, however then S must be at least 100 mm.ExampleThe overtravel time for the entire system is 90ms. Then the above equation gives for the minimum distance: S = (1600 mm/s · 0.09 s) + 250 mm S = 144 mm + 250 mm = 394 mmIf a suitable cover is used, S can be reduced to 144mm (see above).MaintenanceWhat to Do in Once per month, the device must be checked for proper function and for signs of tampering and bypassing of the safety function (to do this, check the wiring of the device and activate the emergency stop function. Check the delay time).The device is otherwise maintenance free, provided that it was installed properly.Note:Additional data can be requested from the manufacturer for applications that deviate from these conditions.SafetyCharacteristics According to EN ISO 13849-1The device is certified according to EN ISO 13849-1 up to a Performance Level of PL e.Safety characteristics according to EN ISO 13849-1 for all variants of ESM-2H2..

Single-Function Safety Relays5-30Visit our website: /catalogsPublication S117-CA001A-EN-PMSR142RTPDescriptionThe MSR142RTP is a versatile monitoring safety relay. It can be connected in four different input wiring configurations: one normally closed, two normally closed, two PNP connections from a light curtain, or a four-wire safety mat. When connected in the two normally closed fashion, the MSR142RTP checks for cross faults across the two inputs. When connected to light curtains, the light curtain must perform the cross-fault detection.The MSR142RTP has output monitoring that can accommodate either automatic/manual reset or a monitored manual reset. When configured with automatic/manual reset (jumpers on X1-X2 and X3-X4), the MSR142RTP can have the reset terminals S33-S34 jumpered or can be converted to an unmonitored manual reset by adding a normally open switch in the monitoring loop (S33-S34). When configured to monitored manual reset, the MSR142RTP checks the output monitoring circuit through the manual application of the reset switch.The outputs include seven normally open safety-rated outputs, four normally closed auxiliary outputs, and two solid-state outputs. One solid-state output indicates that the inputs are closed. The second solid-state output indicates that the safety outputs are active. The safety outputs have independent and redundant internal contacts to support the safety function. The auxiliary outputs are nonsafety outputs intended to provide an external signal about the status of the safety outputs.FeaturesCategory 4 per EN 954-1Stop category 0Light curtain, safety mat, E-stop inputsSeven electromechanical N.O. state safety outputsFour electromechanical N.C. auxiliary outputsTwo solid-state auxiliary outputsCross-fault monitoringMonitored or automatic resetRemovable terminalsLED IndicatorsGreen PowerGreen StartGreen CH1 INGreen CH2 INGreen CH1 output energizedGreen CH2 output energized SpecificationsSafety RatingsStandardsEN 954-1, ISO 13849-1, IEC/EN60204-1,IEC60947-5-1, AS4042.1, ISOTR12100,B11.19Safety ClassificationCat. 4 per EN 954-1 (ISO 13849-1), SIL CL3 perEN IEC 62061, PLe per ISO 13849-1Functional Safety Data 1Note: For up-to-dateinformation, visit/Safety/PFH D: < 1.92 x 10-9MTTFd: > 210 yearsSuitable for performance levels Ple (accordingto ISO 13849-1:2006) and for use in SIL3systems (according to IEC 62061) depending onthe architecture and application characteristics CertificationsCE Marked for all applicable directives, cULus,TÜV, and c-TickPower SupplyInput Power Entry24V AC/DC, 115V AC or 230V AC 50/60 Hz Power Consumption 5 WInputsSafety Inputs1 N.C.,2 N.C., Light Curtain or 4-Wire SafetyMatInput Simultaneity InfiniteInput Resistance, Max.45 ohmsReset Auto./Manual or Monitored ManualPower On Delay/Recovery Time1 s/100 msResponse Time15 msOutputsSafety Contacts7 N.O.Auxiliary Contacts 4 N.C., 2 PNPRated Impulse withstandVoltage2500VSwitching Current @Voltage, Min.10 mA @ 10V DCFuses, Output 6 A slow blow or 10 A quick blow (external) Electrical Life (Operations)220V AC/4 A/880VA cosφ= 0.35…0.1 M220V AC/1.7 A/375VA cosφ= 0.6…0.5 M30V DC/2 A/60 W = 1 M10V DC/0.01 A/0.1 W = 2 MMechanical Life2,000,000 operationsUtilization CategoryInductive: Safety & Aux.:AC-156 A/250V ACInductive: AC-13 3 A/24V DCResistive: DC-1320 mA/30V DC short-circuit protectedUL 4 x B300 or 7 x 4 A ResistiveEnvironmental and Physical CharacteristicsEnclosure Type Rating/Terminal ProtectionIP40 (NEMA 1), DIN VDE 0470-1/IP20Operating Temperature[C(F)]-5…+55° (14…131°)Vibration10…55 Hz, 0.35 mmShock10 g, 16 ms, 100 shocksMounting35 mm DIN RailWeight [g (lbs)]24V: 470 (1.04); 115/230V AC: 607 (1.34) Conductor Size, Max.0.2…4 mm2(24…12 AWG)1Usable for ISO 13849-1:2006 and IEC 62061.

The two solenoids in the valve energize and allow air to flow from the Air Supply to the Air Outlet.STOPPING: Pressing the e-stop button de-energizes the safety outputs of the MSR142, which in turn drops out the solenoids of the safety valve. The valve closes the Air Supply and releases the air pressure to the Air Exhaust. Releasing the e-stop button does not cause the valve to turn back on.Fault DetectionUpon successful completion of internal checks on power up, the MSR142 checks the e-stop status. If an open or short circuit is detected, the MSR142 will not energize its outputs. If both input circuits are properly closed, the MSR142 checks the status of the safety valve. If one or both solenoids of the safety valve are energized, the Status contact will be open, and the MSR142 will not energize its outputs. If both solenoids are de-energized, Status contact will be closed and the MSR142 will turn on its Ready LED. Pressing the Reset button energizes the MSR142 safety outputs and opens the safety valve.The safety valve performs its own internal checks. If one of the valves remains actuated, gets stuck or moves too slowly, the Air Outlet flow will be re-directed to the exhaust. To clear the fault condition, both valves must be de-energized and the valve reset button pressed.+24V DCRatingsThe safety function initiated by the 800F e-stop button meets the safety performance requirements of SIL CL 3 per IEC 62061:2005 and has Category 4structure that can be used in systems requiring Performance Levels up to PLe per ISO 13849-1: 2006. The MSR142 has seven safety rated outputs. To maintain the highest safety levels, these outputs must drive redundant actuators which must be monitored for proper performance. This example circuit performs a Stop Category 0 function (coast to stop).Allen-Bradley 440R-G23216。

The SRM provides three normally open (NO) and one normally closed (NC) contactsper alarm input, allowing you to add alarm contacts for your safety processes without specialinstallation or configuration.Relay TerminologyNormal is the term used to describe the “shelf-state” of relay contacts. The contacts of aNormally Open relay are open (infinite resistance) when the relay is not energized. The contactsof a Normally Closed relay are open when the relay is energized (closed when not energized).Note: Sometimes a non-alarm input level is referred to as being in a “normal” condition. Thispractice is intentionally avoided in this manual. Do not confuse the term “normal”, as in NormallyOpen or Normally Closed, with a non-alarm input condition. In this manual, “normal” is anexclusive reference to the shelf state or quiescent state of an alarm’s relay contacts, whetheropen or closed.SRM ApplicationsPlease refer to Section 5: Applications for examples of typical SRM applicationsModel Numbers and OptionsThe following section provides details of the Moore Industries model number and the availableoptions for the SRM.Moore Industries model numbers for SRM are structured as follows:SRM / CC / 3RO / 24DC / [DIN]Unit / Input / Output / Power / - Options [Housing]Refer to Section 8 Ordering Information for a quick reference table of ordering information.

To mount the SRM on a Top-Hat DIN-rail, seat the upper extrusion on the unit back panel over the top lip of the rail and pivot downward until the housing locks into place.When mounting multiple units, like a rack or cabinet, make sure to allow adequate vertical spacing for pivoting the units.Equipment RatingsThe SRM accepts a contact closure input and switches outputs up to 5A at up to 250 Vac or 30 Vdc for NO contacts and 1A at up to 250Vac or 30Vdc for NC contacts. It does not generate hazardous voltages but may switch hazardous voltages (>50Vac) on its output contacts. Products connected to the SRM should be designed to receive this type of input.Warning: If this unit is used in a manner not specified by Moore Industries, the protection provided by the equipment may be impaired.24Vdc Supply WiringAll power connections should be made with 14 or 20 AWG (2.0mm2 or 0.52mm2) wire.The end of each conductor should be stripped no more than 0.25in (7mm). The end of the stripped wire should be tinned with solder, or inserted into a ferrule and crimped before being placed into a terminal block.Tighten the screws on the terminal block to 4.4 - 5.3 lbf•in (0.5 - 0.6 N•m).Input/Output WiringThe Input/Output connections can be made with 14 to 22 AWG (2.0mm2 or 0.33mm2) wire.If high voltage/currents are being switched on the relay contacts then 14 or 16 AWG (2mm2 or 1.3mm2) wire is recommended.The end of each conductor should be stripped no more than 0.25in (7mm).Tighten the screws on the terminal block to 4.4 - 5.3 lbf•in (0.5 - 0.6 N•m).Protective Earth ConductorThe Protective Earth Conductor shall be of equal or larger size wire than the other two power conductors.The Protective Earth Conductor shall be the first conductor connected to the unit when the unit is being wired. It shall be the last conductor removed when the unit is beingun-wired.Note: Some of Moore Industries’ instruments can be classified as receivers (IPT2, IPX2, etc.) and some can be classified as transmitters (TRX, TRY, etc.) while some are both a receiver and a transmitter (SPA2, HIM, etc). Hence, your shield ground connections should be appropriate for the type of signal line being shielded. The shield should be grounded at the receiver and not at the signal source.Contact/Load ProtectionThe supply powering the contact/load shall be protected by a UL approved branch circuit fuse or breaker, rated 250 Vac, 10 Amp.Contact/Load SuppressionThe SRM’s CC (Contact Closure) input circuit includes an internal snubbing diode across it’s relay coil which means there is no need for any external suppression across the input terminals.The SRM does not provide any surge suppression across its relay contacts. When the instrument relays are used to switch an inductive load such as an external relay coil, contactor, solenoid inductive load, large voltage spikes may be created in nearby cable harnesses. When excessive, these voltage spikes can disrupt the operation of all nearby electronics including this product. Inductive loads should have suppression devices installed at the load (for external relays this would be right across the relay coil itself). Usually this is a simple diode for dc circuits. AC circuits routinely use an R-C snubber. Please follow the external load manufacturer instructions for their recommended suppression kits.Caution: If suppression devices are not installed on inductive loads, the SRM unit may be damaged. This damage could include blowing of replaceable fuses on the relay outputs (see Maintenance section for fuse replacement).Please contact Moore Industries’ Customer Service for further technical assistance.CE Certification-related GuidelinesInstallation of any Moore Industries’ products that carry the CE marking must adhere to the guidelines in the Recommended Ground Wiring Practices section in order to meet the EN 61326 requirements set forth in the applicable EMC directive.The Low Voltage Directive also applies to the SRM when connecting any of its output relay con-tacts to voltages greater than 50 vac. In order to comply with EN61010-1 (Low Voltage Directive) all guidelines in this section must be followed.•Input LED – When the SRM Input is open, the Input LED will be red. When the SRM Input isclosed, the Input LED will turn green.•Output LED – When the Normally Open terminals are closed and the Monitor terminal is open, the Output LED will be green. When the Normally Open terminals are open and the Monitor terminal is closed, the Output LED will be red.•Power LED – The Power LED will be green when appropriate power is supplied to SRM. If there is power applied to the unit and the power led is off, the power fuse may be blown and need to be replaced (see Maintenance section).If both input and output LED s are correct but any of the outputs are stuck open, the fuse on the stuck output may be blown and need to be replaced (see Maintenance section).Note: Applications that require wiring the SRM’s CC input to a “wet” contact (24Vdc) instead of voltage free Contact Closure (see Applications Figure 5.3) will either show all green LEDs when the contact/relay output is closed or all LEDs will be off (dark) when the contact/relay output isopen. If there are any red LEDs displayed then this indicates a relay failure or blown fuse.Figure 4.2.

An extinguished Power LED may indicate that the power fuse has been blownand needs replacing, the power input is less than the appropriate amount or that no power is currently applied to the unit.• Input LED – When the SRM Input is open, the Input LED will be red. When the SRM Input is closed, and the Input LED will turn green.• Output LED – When the SRM Input is open, the Output LED will be red. When the SRM Input is closed, the relay becomes energized and the Output LED will turn green.The Input and Output LEDs provide a visual diagnostic for the SRM. Both LED colors should always match unless there is a relay failure such as stuck contacts.Note: Applications that require wiring the SRM’s CC input to a “wet” relay output (24Vdc) instead of voltage free Contact Closure (see Applications Figure 5.3) will either show all green LEDs when the contact/relay output is closed or all LEDs will be off (dark) when the contact/relay output is open. If there are any red LEDs displayed then this indicates a relay failure or blown fuse.Process Safety TimeProcess safety time is the minimum time from the initiation of a hazardous event to the point where the hazardous event is unavoidable. Any safety function designed to either prevent the event or at least mitigate its effect must be capable of performing its specified safety function in a time period very much less than the process safety time.The SRM has a characteristic response time (end-to-end) of <50mSec.Moore Industries-International, Inc.- 21 -User’s Manual 225-765-00GRepair and ReplacementThe SRM has replaceable fuses (see Maintenance section). After replacing any fuses, it is recommended to run the proof test procedure before returning the unit back to service. Except for the fuses, the SRM is not intended to be repaired on site and has no components needing maintenance or regular replacement. On device failure, the SRM should be returned to Moore Industries World Headquarters in North Hills, CA U.S.A. for repair and refurbishment (refer to Returns Procedures at the end of this manual).Warning: Replacement fuses must be exactly the same size, type, voltage and current rating as specified in the Maintenance section. Any deviations could create a safety hazard and will invalidate any remaining warranty.With the exception of fuses, repair or replacement of any component without authorization from Moore Industries will invalidate any remaining warranty.Recording and Reporting of SRM PerformanceIt is the end user’s responsibility to maintain records of all safety components failures, especially those that might be classified as potentially dangerous.This feedback data not only helps the supplier identify and rectify reliability issues but also to provide quantitative data to increase confidence in the FMEDA analysis of dangerous failurerates. Please ensure that any components returned to Moore Industries are returned with a clear report identifying the fault experienced.Safety Relay ModuleSRMUser’s Manual225-765-00GSafety Relay ModuleSRM Moore Industries-International, Inc.- 22 -Moore Industries-International, Inc.- 23 -User’s Manual 225-765-00GSafety Relay ModuleSRMSpecifications and Information subject to change without notice.User’s Manual 225-765-00GPart Number 700-702-35FMEDA Report consistent with IEC 61508-2:2002 providing the information necessary to design a Safety Instrumented System (One copy provided free with each order Upon Request).Safety Relay ModuleSRM Moore Industries-International, Inc.- 24 -Specifications and Information subject to change without notice.© 2015 Moore Industries-International, Inc.。

RT6Safety relayWould you like a single safety relay for all your safetyapplications?Then choose the RT6 universal relay to supervise both yoursafety devices and the internal safety of your machinery. Inaddition you can select the safety level required for eachinstallation. All this is possible because the RT6 has the mostversatile input option arrangement available on the market.Many other relays can therefore be replaced by the RT6.The relay also comes with other options such as manualor automatic reset. Manual supervised reset can be usedfor gates and other safety devices that can be bypassed.Automatic reset can be used for small hatches, if deemedacceptable from risk assessment.The RT6 also has information outputs that follow the in-puts and outputs of the relay. These outputs will for exampleindicate if a gate is open or closed and if the safety relayneeds to be reset.The RT6 is designed with a minimum amount of compo-nents thus keeping both production costs and componentacquisitions to a minimum.Choose the RT6 to simplify your safety circuits and reduceyour costs.Safety relay for:Emergency stopsLight curtainsThree position devicesInterlocked gates/hatchesMagnetic switchesLight beamsFeatures:Five input optionsSingle or dual channel inputManual supervised or auto-matic resetTest input for supervision ofexternal contactorsWidth 45 mmLED indication of supply,inputs, outputs, short-circuitand low voltage level.3 NO / 1 NC relay outputsTwo voltage free transistorinformation outputsSupply 24 VDC, 24, 48,115 or 230 VACQuick release connectorblocks123456789101112InputsThe RT6 can be configured to operate with any of the following input options:1. Single channel, 1 NO contact from +24 V DC, safety cat. 1.2. Dual channel, 2 NO contacts from +24 V DC, safety cat.3.3. Dual channel 1 NO, 1 NC contact from +24 V DC, safety cat. 44. Dual channel, 1 NO contact from 0V and 1 NO contact from +24 V DC, safety cat. 4.5. Safety mats/contact strips 1 ‘contact’ from 0V and 1 ‘contact’ from +24 V DC, safety cat. 1.When the input/inputs are activated and the test/supervised reset is complete, relays 1 and 2 are energized. Simultaneous activation is not required where there are dual channels. The two relays are de-energized when the input/inputs are de-activated in accordance with the input option chosen or in case of a power failure. Relays 1 and 2 must both be de-energized before the outputs can be activated againTransistor output status informationThe RT6 has two voltage free transistor outputs that can be con-nected to a PLC, computer or other monitoring device. These outputs give the input and output status of the relay.Reset and testingThe RT6 has two reset options; manual and automatic. The manual supervised reset is used when the RT6 is monitoring safety devices that can be bypassed, i.e. to ensure that the outputs of the safety relay do not close just because a gate is closed. The automatic reset should only be used if deemed an acceptable risk.In addition, the RT6 can also test (supervise) whether, for ex-ample, contactors and valves etc are de-energized/de-activated before a restart is allowed.Indication of low voltageThe ‘On’ LED will flash if the relay supply voltage falls below an acceptable level. This indication will also be given if a monitored safety mat/contact strip is actuated. See connection option 5.Safety levelThe RT6 has internal dual and supervised safety functions. A short-circuit, internal faulty component or external interference will not present a risk to options with the highest safety level. A manual reset requires that the reset input is closed and opened before the safety relay outputs are activated. A short-circuit or a faulty reset button is consequently supervised.When the RT6 is configured for dual channel input, both the inputs are supervised for correct sequence operation before the unit can be reset.The input options 3 and 4 have the highest safety levels as all short-circuits and power failures are supervised. This in combination with internal current limitation makes the relay ideal for supervision of safety mats and contact strips.Regulations and standardsThe RT6 is designed and approved in accordance with appropri-ate directives and standards. Examples of such are 98/37/EC, EN ISO 12100-1/-2, EN 60204-1and EN 954-1/EN ISO 13849-1.Connection examplesFor examples of how our safety relays can solve various safety problems, see the section “Connection examples”.Technical information - RT6Connection of supply - RT6The RT6 DC option should be supplied with +24 V on A1 and 0 V on A2.The RT6 AC option should be supplied with the approprate supply voltage via connections A1 and A2.The S23/ must be connected to protective earth.NoTeWith both DC and AC modules, if cable shielding is used this must be connected to an earth rail or an equivalent earth point.**Only for AC supplyDC-supply of AC-unitsAll AC-units can also be supplied by +24 VDC to S53 (0VDC to S23).DC supplyAC supplyThe input (contact to S14) must be closed before the outputs can be activated. When the input contact is opened the relay safety output contacts open.*Connection of safety devices - RT6Both input contacts (S14 and S34) must be closed before the relay outputs can be activated. The safety relay contacts will open if one or both of the input contacts are opened. Both the input contacts must be opened and reclosed before the relay can be reset. A short-circuit between inputs S14 and S34 can only be supervised if the device connected to the inputs has short-circuit supervised outputs, e.g. JOKAB Focus light curtains.can be activated. The safety relay contacts will open if one or both of the inputs change state or in case of a short-circuit between S14 and S44. Both inputs must return to their initial positions before the relay outputs can be reactivated.Reset connections - RT6The manual supervised reset contact con-nected to input X1 must be closed and opened in order to activate the relay out-puts.Automatic reset is selected when S53, X1 and X4 are linked. The relay outputs are then activated at the same time as the inputs.*connected to S13 for safety mat/contact stripContactors, relays and valves can be supervised by connecting ‘test’ contacts between S53 and X1. Both manual super-vised and automatic reset can be used.Testing external contactor statusoutput connections - RT6The RT6 has three (3 NO) safety outputs and 1 NC information output.In order to protect the output contacts it is recommended that loads (inductive) are suppressed by fitting correctly chosen VDR’s, diodes etc.Diodes are the best arc suppressors, but will increase the switch off time of the load.The RT6 has two(2) voltage free transistor outputs for information.The transistor outputs are supplied with voltage to Y13, either from S53 (+24V) or an external 5-30 VDC supply. Y14 and Y24 follow the relay inputs and outputs as follows:• Y14 becomes conductive when the relay input conditions are fulfilled.• Y24 becomes conductive when both the output relays are activated.***NoTeThese outputs are only for information purposes and must not be connected to the safety circuits of the machinery.One input contact must be closed (S14) and one opened (S44) before the relay outputs 1. SINGLe CHANNeL, 1 No from +24V 2. DUAL CHANNeL, 2 No from +24V3. DUAL CHANNeL, 1 No, 1 NC from +24V4. DUAL CHANNeL, 1 No from +24V, 1 No to 0VRelay functions as for option 2, but a short-circuit, in this case between inputs S14 and S24, is supervised (safety outputs are opened).Both ‘contact’ inputs from a inactivated safety mat/contact strip must be made in order to allow the RT6 relay outputs to be activated. When the safety mat/contact strip is activated or a short-circuit is detected across S14-S23, the relay will de-energize (safety outputs open) and the ‘ON’ LED will flash. As output S13 has an internal current limit of 70 mA, the RT6 will not be overloaded when the mat/contact strip is activated or a short-circuit is detected.5.
