Basic Device SNO 4003K Basic device for single-channel emergency stop and safety gate monitoring Stop category 0 according to EN 60204-1 Applications up to safety category 2 according to EN 954-1

28 Basic Device SNO 4003K Basic device for single-channel emergency stop and safety gate monitoring Stop category 0 according to EN Applications up to safety category 2 according to EN Safety category of the device: 4 according to EN Manual or automatic start 3 enabling current paths, 1 signaling current path Feedback loop for monitoring external contactors Applications Protection of people and machinery For immediate interruption of the power supply stop category 0 Monitoring of emergency stop applications Monitoring of safety gates Protective measures in sections of the safety system Function The device is a single-channel switching device for emergency stop applications with self-monitoring on each ON-OFF cycle. It complies with EN and is equipped with positively driven relays. The device has two reset inputs Y2 (without reset monitoring) or Y3 (with reset monitoring). The relays K1 and K2 are actuated either after the reset button (on Y1-Y3) has been pressed or automatically (bridge Y1-Y2). They become self-locking through their own contacts, if there is an electrical connection between terminal A1 and the supply voltage (emergency stop button, position switches). After this switch-on phase the enabling current paths are closed and the signaling current path is open. If the electrical connections between terminal A1 and the supply voltage are interrupted, the enabling current paths open and the signaling current path closes. The energized state (self-locking) of the two channels is indicated by a green LED K1, K2. The second green LED indicates that supply voltage has been applied. The set-up of an emergency stop facility after stop category 0 (EN ) is possible. The device corresponds to category 4 for safety-related parts of controls (EN 954-1).

It complies with EN and is equipped with positively driven relays. Basic function: With supply voltage applied to terminals A1/A2 and the safety inputs closed, operating of the reset button closes the enabling current paths (manual start). When the safety inputs are opened/de-energized the enabling current paths will open. Operating modes / system functions Single or two-channel control With single-channel control both safety channels CH1 and CH2 are connected in parallel; with two-channel control they are switched separately. Without cross monitoring Both safety channels are switched to the positive potential (S12 and S31 to S11). With cross monitoring Safety channel CH1 is switched to the positive potential (S11 to S12), and safety channel CH2 to the negative potential (S21 to S22). Manual start When the safety inputs are closed, a button is used to open reset input S34 (triggering with falling edge) or to close reset input S35 (triggering with rising edge). Automatic start Reset input S35 is connected to S33. The device starts with the rising edge of the signal on safety input S12. Start inhibit After supply voltage has been applied and the safety inputs closed, the enabling paths will not close. Starting is only possible after the reset button has been operated. For start inhibit the reset inputs have to be controlled with the button, as with manual start mode. Restart inhibit No restart after the safety inputs have been opened and closed. Restarting is only possible after the reset button has been operated. For restart inhibit the reset inputs have to be activated with the button, as in manual start mode. Semiconductor compatible OSSD (output signal switching devices) signals from a light curtain or other safety sensors with semiconductor outputs can be processed. Test pulses <t TP do not influence the device functions. Test pulses >t TP can lock the device. Synchrocheck With two-channel control both safety channels are monitored against one another with the synchronous time t S. Safety channel CH1 must close before CH2 and bridge S33/S35 must be connected. If CH2 closes before CH1, the synchronous time t S = and synchrocheck is switched off. SNO 4062KM The function of this device corresponds to that of the SNO 4062K without synchrocheck. The device is suitable for connecting to light curtains for Si category 4 and connecting to short-circuit forming 4-wire safety mats, switching strips or switching edges (without monitoring resistance). Safety mats The device must be operated with two channels and cross monitoring. If there is resistance < 50 Ω / channel and a short circuit between the channels (S11/S12 and S21/S22) the enabling paths open and the SUPPLY LED flashes. Light curtain for Si category 4 The device will be operated with two channels and without cross monitoring, if the light curtain connected to the OSSD detects a shunt fault on its own. Input debouncing Input debouncing prevents fast consecutive switching of the enabling current paths when the safety inputs are opened for less than t ASP. Safety inputs opened for longer than t ASP lead to opening of the enabling current paths after t R. Restarting is blocked for time t SP.

It complies with EN and is equipped with positively driven relays. Basic function After supply voltage has been applied to terminals A1/A2 and the safety inputs closed, operating of the reset button closes the enabling current paths (manual start). When the safety inputs are opened/de-energized the enabling current paths will open. Operating modes / system functions Single or two-channel control With single-channel control both safety channels CH1 and CH2 are connected in parallel; with two-channel control they are switched separately. Without cross monitoring Both safety channels are switched to the positive potential (S12 and S31 to S11). With cross monitoring Safety channel CH1 is switched to the positive potential (S11 to S12), and safety channel CH2 to the negative potential (S21 to S22). Manual start When the safety inputs are closed, a button is used to open reset input S34 (triggering with falling edge) or to close reset input S35 (triggering with rising edge). Automatic start Reset input S35 is connected to S33. The device starts with the rising edge of the signal on safety input S12. Start inhibit After supply voltage has been applied and the safety inputs closed, the enabling paths will not close. Starting is only possible after the reset button has been operated. For start inhibit the reset inputs have to be controlled with the button, as with manual start mode. Restart inhibit No restart after the safety inputs have been opened and closed. Restarting is only possible after the reset button has been operated. For restart inhibit the reset inputs have to be activated with the button, as in manual start mode. Semiconductor compatible OSSD (output signal switching devices) signals from a light curtain or other safety sensors with semiconductor outputs can be processed. Test pulses <t TP do not influence the device functions. Test pulses >t TP can lock the device. Synchrocheck With two-channel control both safety channels are monitored against one another with the synchronous time t S. Safety channel CH1 must close before CH2 and bridge S33/S35 must be connected. If CH2 closes before CH1, the synchronous time is t S =. NO 4063KM The function of this device corresponds to that of the SNO 4063K without synchrocheck. The device is suitable for connecting to light curtains for Si category 4 and to short-circuit forming 4-wire safety mats, switching strips or switching edges (without monitoring resistance). Safety mats The device must be operated with two channels and cross monitoring. If there is resistance < 50 Ω / channel and a short circuit between the channels (S11/S12 and S21/S22) the enabling paths open and the SUPPLY LED flashes. Light curtain for Si category 4 The device will be operated with two channels and without cross monitoring, if the light curtain connected to the OSSD detects a shunt fault on its own. Input debouncing Input debouncing prevents fast consecutive switching of the enabling current paths when the safety inputs are opened for less than t ASP. Safety inputs opened for longer than t ASP lead to opening of the enabling current paths after t R. Restarting is blocked for time t SP. For applications with tactile operating modes (rapid ON-OFF cycles, for example at manual supply) we recommend the use of SNO 4063KM.

The control logic of relay K1 controls relays K2 and K3. which become self-locking through their own contacts. After this switch-on phase the three enabling current paths defined for the output are closed (terminals 13/14, 23/24, 33/34) and the signaling current path opened (terminals 41/42). This is indicated by 3 LEDs that are assigned to safety channels K2, K3 as well as to the supply voltage. If the emergency stop button is activated, the current supplies for the relays K2 and K3 are interrupted. The enabling current paths on the output are opened or the signaling current path is closed. With a two-channel wiring of the emergency stop button and cross-monitoring wiring of the emergency stop button circuit, additional errors such as shunt fault or ground fault can be detected. An electronic fuse protects the emergency stop relay against damage. After the cause of the malfunction has been removed, the device is operational again after approx. 2 s. Reset button monitoring The emergency stop relay is equipped with/without reset button monitoring. During reset button monitoring (terminal Y13) the device is only enabled with the falling edge of the reset button. This feature only allows a static operation of the device. For starting the reset button must always be pressed and released. It is not possible to perform an automatic start by jumpering the reset button (see function diagram FD W1). Operation without reset button monitoring (terminal Y14) is suitable for dynamic operation (automatic start). The reset button can be jumpered. This function is required for safety gate applications (see function diagram FD W1). Overview of devices / Part numbers Type Rated voltage Terminals Part no. Std.

40 Basic Device SNL 4062K Light barrier evaluation and test device Stop category 0 according to EN Applications up to safety category 3 according to EN Safety category of the device: 3 according to EN For electrosensitive protective equipment type 2 according to EN Cyclic tests, override function, reset button monitoring, cross monitoring 2 input channels, control through single-channel or two-channel contacts or semiconductors 2 enabling current paths, 1 signaling current path Applications Monitoring of one-way safety light barriers with test input Emergency stop and safety gate applications Protection of people, material and machinery in a transfer area; access protection Function The light barrier evaluation and test device SNL 4062K operates as the interface between optoelectronic equipment according to EN /-2 type 2 and the machine control. The device is used to protect hazardous areas around powered machinery and provides the following integrated features: start disable, restart disable, override, self test, cyclic test, time monitoring, feedback loop and output circuit via positively driven relays. With supply voltage applied to terminals A1/A2 a self test is performed after which the device is ready to operate. If the self test fails, the program is aborted and a restart is necessary. Further activation of the device depends on the results of the self test, the selected operating mode and the status of the external connected circuit (see Function flowchart ). Compliance of the light barrier signals at inputs Y12 and Y22 with those at outputs Y41 and Y42 is checked and displayed by the READY LED. Depending on the selected function and with the light barrier inputs actuated, the enabling current paths of the SNL 4062K either switch into the ON position (operation without start inhibit), or they remain in the OFF position until the reset key is pressed and released again (restart inhibit). Two NO contacts and one signaling current path (NC contact) are available as enabling current paths. The state of the outputs is displayed by the multicolored OSSD LED. green light = enabling current paths in ON position red light = enabling current paths in OFF position The enabling current paths are switched off when one of the following events occurs: 1. The light barrier inputs are de-energized in case they have been previously enabled. 2. The override input is also de-energized during the override operation in case the light barrier inputs were previously disabled. 3. A fault has been detected during the cyclic self test. 4. If both light barrier inputs are energized during the override operation. Override: When the safety device is jumpered, it is not guaranteed that relays K1 and K2 (OSSD) are switched off as long as the override signal is applied (operating mode: static input signal). After activation of the safety function the SNL 4062K will switch into the operational state All device-internal tests and starting cycle tests are performed again. If no errors are found during the starting cycle tests, operation can be continued. The device is delivered with jumpered terminals. Operating modes Selectable function features: Test pulse direction (pos./neg. pulse) Restart inhibit (ON/OFF) Override (static/dynamic) The operating mode can be pre-set on the rear of the housing using the DIP switches (see Operating modes ).

It complies with EN and is equipped with positively driven relays. It is intended for monitoring connected switching elements on separating safety devices and generating a safety-oriented signal (enable). Depending on the design, separating safety devices may include sliding safety gates, safety gates, housings, covers, sheetings, screens, etc. Basic function With supply voltage applied to terminals A1/A2 and the safety inputs closed, operating of the reset button closes the enabling current paths (manual start). When the safety inputs are opened the enabling paths will open. Operating modes / system functions Two-channel control The device uses two-channel control. With equivalent control safety channel CH1 is connected via positive potential, safety channel CH2 via negative potential. With non-equivalent control both safety channels are connected to the positive potential. Cross monitoring With equivalent control cross monitoring is achieved by means of the short-circuit principle; with non-equivalent control it is achieved through function diversity. Manual start When the safety inputs are closed, a button is used to close reset input S34 and open it again (triggering with falling edge) or to close reset input S35 (triggering with rising edge). Automatic Start Reset input S35 is connected to S33/S14. The device starts with the rising edge of the signal on safety input S14. Start inhibit After supply voltage has been applied and the safety inputs closed, the enabling paths will not close. Starting is only possible after the reset button has been operated. For start inhibit the reset inputs have to be activated with the button, as during manual start mode. Restart inhibit No restart after the safety inputs have been opened and closed. Restarting is only possible after the reset button has been operated. For restart inhibit the reset inputs have to be activated with the button, as in manual start mode. Synchrocheck Synchrocheck is only possible in automatic start mode (bridge S33/S14 S35). Safety channel CH2 must close (S24) or open (S22) after safety channel CH1 within synchronous time t S.

The safety behavior of the device is designed for applications according to category 4 (EN 954-1). The device is single-fault safe and self-monitoring. Synchronous activation of both actuators (two-hand momentary contact or safety gate contacts) is monitored. Each of the two actuators is connected to the device with a NO contact and a NC contact. The technical design of the input circuit provides cross connection and ground fault monitoring. The output function is designed with 2 NO contacts as an enabling current path and 1 NC contact as signaling current path (all positively driven). With supply voltage applied to terminals A1/A2 and the feedback loop (terminals Y1/Y2) closed, the enabling current paths are closed by simultaneously activating the actuators (S1+S2). Both actuators must be activated within 0.5 s for the output contacts to be enabled. If only one of the two actuators is released, the device is immediately de-energized. The enabling current paths open. The device can be restarted only after both actuators have returned to their initial position (for example when the two-hand momentary contact switches have been released) and the feedback circuit is closed again. The feedback circuit should only be opened again after both actuators are activated. Otherwise the device will remain in the OFF position. The current status of the device is indicated by 3 LEDs: application of the supply voltage with LED SUPPLY, activation of both actuators with LED K1 and additionally with LED K2 in case of synchronous activation.

This controls controls the K1 to K4 relays that become self-locking (when starting through reset button monitoring after the response time). After this switch-on phase the 3 enabling current paths are closed (terminals 13/14, 23/24 and 37/38). Three LEDs display the state of the relays K1/K2, K3/K4 and the supply voltage. If the emergency stop button is activated, the current supplies for the relays K1 to K4 are interrupted. The undelayed enabling current paths (terminals 13/14, 23/24) are opened with release time tr1 while the off-delayed enabling current path (terminals 37/38) is opened after the pre-set OFF-delay time tr2. The OFF-delay time can be adjusted infinitely in the range 0.15 to 3 s or 1.5 to 30 s. With a two-channel control and cross-monitoring wiring of the sensor circuit, additional errors such as shunt fault or ground fault can be detected. An electronic fuse protects the device against damage. After the cause of the malfunction has been removed, the device is operational again after approx. 3 s. Reset button monitoring The device can be started either with the falling edge or with the rising edge (terminals S34 or S35). For emergency stop applications with manual start the button must be connected to terminals S33/S34. The device is enabled only with the falling edge of the reset signal. For starting the reset button must be pressed and released. For safety gate applications in which an automatic start shall be performed it is necessary to jumper terminals S33/S35. The device will react at the rising edge of input S12 that is internally connected to S33. Synchrocheck The use of safety limit switches for single-channel or two-channel circuits in safety gate applications depends on the required safety level. The device offers a two-channel control along with an optional synchrocheck of the limit switches. A synchronous time ts 0.5 s requires limit switches positioned in a way that channel 1, terminals S11/S12, closes before channel 2, terminals S21/S22. If channel 2 closes before channel 1, the synchronous time is ts =.

The device is designed with two channels and redundancy. The enabling current paths are separated from the control circuits and signaling circuits with creepage distances and clearances > 5.5 mm (safe isolation). There is basic insulation to separate the enabling current paths from one another and the control circuits from the signaling current paths. The broad input voltage range of DC 15 V to DC 30 V makes the SNE 4003K ideal for single-channel or two-channel control by semiconductors. Description of functions Input voltage to the SNE 4003K is routed via one or two enabling current paths of a basic device. When the input voltage is applied relays K1 and K2 switch into the ON position. After this switch-on phase, enabling current paths 13/14, 23/24, 33/34 are closed and feedback current path Y1/Y2 and signaling current path 41/42 are opened. This is displayed through two LEDs, K1 and K2, which are assigned to relays K1 and K2. If the enabling current paths of the basic device are opened when the emergency stop button is operated, relays K1 and K2 on the SNE 4003K switch back into the OFF position. The enabling current paths open and the feedback current path closes. Feedback current path Y1/Y2 prevents the basic device from switching on again before K1 or K2 releases. SNE 4003K / K-A 52

When the supply voltage is applied relays K1 and K2 switch into the ON position. After this switch-on phase the four enabling current paths 13/14, 23/24, 33/34, 43/44 (of the SNE 4004K) or 17/18, 27/28, 37/38, 47/48 (of the SNE 4004KV) are closed and the feedback current path Y1/Y2 is open. This is displayed through two LEDs that are assigned to relays K1 and K2. When the enabling current paths of the basic device are opened through the operation of the emergency stop button, relays K1 and K2 on the SNE 4004K switch back into the OFF position. The enabling current paths open and the feedback current path closes. Feedback current path Y1/Y2 prevents the basic device from switching on again before K1 or K2 releases. SNE 4004KV The functions of this device correspond to those of the SNE 4004K. The SNE 4004KV is available with the following four OFF-delay times tr1: 0.5 s; 1 s; 2 s and 3 s. The device has an OFF-delay time that is enabled through capacitors. This causes the OFF-delay time R1 to elapse completely even in case of failure of the power supply (A1/A2). It cannot be deleted before it has elapsed. Upon timing-out the relays K1 and K2 switch into the OFF position. OFF-delay times of > 0 s correspond to stop category 1. SNE 4004K-A and SNE 4004KV-A The functions of these devices correspond to those of the SNE 4004K or SNE 4004KV. Devices with the -A identification in their type designation are equipped with four removable pluggable terminals (see the K4-2 dimension diagram).

It has a feedback current path with a serial NC contact chain of positively driven relays involved in the switching operation for a safe feedback to the basic device. Two serially switched NO contacts (one NO contact for each redundant relay) form an enabling current path. Due to this design it is generally possible to establish a safety circuit with self-monitoring on each ON-OFF cycle (SK4) in conjunction with a suitable basic device. As the device is designed with a single channel, it must be installed in a control cabinet with permanent wiring in order to prevent short circuits of the control lines. A basic isolation separates the enabling current paths from one another as well as from the control circuits and the signaling path. Description of functions Input voltage to the device is routed via one or two enabling current paths of a basic device. When the input voltage is applied relays K1, K2, K3 and K4 switch into the ON position. After this switch-on phase the enabling current paths 13/14, 23/24, 33/34, 43/44 and 63/64, 73/74, 83/84, 93/94 are closed and the feedback current path Y1/Y4 as well as the signaling current paths 51/52, 101/102 and 111/112 are opened. This is displayed through the LEDs K1, K2, K3 and K4 which are assigned to relays K1, K2, K3 and K4. When the enabling current paths of the basic device are opened through the operation of the emergency stop button, relays K1, K2, K3 and K4 switch back into the OFF position. The enabling current paths open and the feedback current path closes. Feedback current path Y1/ Y4prevents the basic device from switching on again before K1, K2, K3 and K4 releases. The feedback current path Y1/Y2 must be wired to the reset or feedback loop of the basic device. SNE 4008S * pre-wired by the manufacturer 56

65 samos samos Diversity of function samos offers input circuit functions for a wide range of typical machine-building and plant engineering functions through to special functions for special sensors. Even a stand-alone base module offers numerous application options and covers the functionality of many types of conventional single safety switching device. The maximum control category (2, 3 or 4; EN 954-1) depends on the sensor, the wiring and the installation. Economical safety With all its advantages samos is more cost-effective than the normal safety switching devices, even with just a few safety channels. Just two samos modules and 45 mm can replace up to 6 dualchannel safety switching devices at the same cost. And for larger configurations the samos system is the clear winner. Another advantage: modular flexibility makes investment mistakes almost impossible. samos 65

66 LG2 FB2 LG1 FB1 SD Zone 0 Zone 1 Zone 2 Field bus Easy Practicability A machining center with two machines, a robot for handling the parts, feed belts a standard setup in industrial manufacturing. Comprehensive safety monitoring is obligatory. What you need is flexibility, so that not every malfunction leads to total shutdown, and, for example, setup mode is still possible. 66

67 samos samos Safety Zones samos offers the flexible solution for this safety task, through its modular design and the possibility of setting up input group hierarchies. This means you can create zones where different safety responses are triggered according to place and type. Operating one of the three emergency stop switches in zone 0 shuts the machining center down completely in zones 0, 1 and 2. If light curtain LG1 is interrupted by a person, the machines, the robot and feed belt FB1 are shut down. If light curtain LG2 is interrupted by a person, all dangerous motions and feed belt FB2 are shut down. Muting sensors bridge the light curtain function briefly to allow normal material transport through the light curtain. samos also monitors the muting sensors. When the safety door SD is opened only zone 2 is shut down. Feed belt FB2 can still transport material to the next machining station. However, personnel can enter the shut-down zone 2 for setup operation after the lockswitch and the enabling button have been operated. Jog mode is used, for example, for movements during setting up. Emergency stop and light curtain monitoring remain active. The settable release delay on the samos outputs means that in all robot and machine shutdowns, stop category 1 is used for controlled stopping. samos The optional field bus connection sends the input/output status, for example to a higher-order PLC. The PLC in turn can reset individual zones via the field bus. 67

The input modules are permanently coded and are always permanently assigned to a likewise coded basic module, which eliminates any confusion during service work, for instance.

71 samos samos Maximum flexibility Intelligently connected modules The modules are connected to a 36-mm standard DIN rail and pushed together. The obligatory basic module is connected on the left side of the rail and any necessary additional basic slave modules, input modules and output module relays are connected in between. The input modules are permanently coded and are always permanently assigned to a likewise coded basic module, which eliminates any confusion during service work, for instance. The relay modules are integrated in the function via external wiring. If necessary such subsystems made up of basic modules, input modules and output modules can be wired together. This allows the implementation of a wide variety of input/output functions with separate or combined effects. Functions with added value The functions of the basic module and the input modules are set either individually or in combination on the front with 10-position rotary switches (e.g. emergency stop and protective door monitoring with controlled shutdown). Additional functions such as automatic reset, startup and re-startup blocking or retriggering of the off-delay are implemented with terminal configuration. samos The clear and simple user interface helps to implement safe solutions. 71
