The 3RU11 thermal overload relays come with screw terminals. The electronic overload relays 3RB20 and 3RB21 are available with screw terminals (box terminals) or spring-type terminals on the auxiliary current side; the same applies for the evaluation modules of the 3RB22 to 3RB24 electronic overload relays for High-Feature applications. 3/7 Siemens Industry, Inc. Industrial Controls Catalog 7/78 Siemens IC 10 · 2012 Overload Relays SIRIUS Thermal Overload Relays 3RU11, 3RU21 up to 100 A, CLASS 10 Description The 3RU thermal overload relays can protect your loads from overload and phase failure. You must implement short-circuit protection (see "Short-circuit protection") by means of a fuse or circuit-breaker. The 3RU thermal overload relays are environmentally friendly 3/8 (see "Environmental considerations") and comply with all the main international standards and approvals (see "Specifications" and "Increased safety type of protection EEx"). The accessories for the 3RU thermal overload relays have been designed on the principle that all requirements are covered by a small number of variants. Application The 3RU thermal overload relays are designed for the protection of three-phase and singlephase AC and DC motors. If single-phase AC or DC loads are to be protected using 3RU thermal overload relays, all three bimetal strips should be heated. Therefore all main circuits of the relay must be connected in series. NSB0_02075a The 3RU thermal overload relays up to 100 A are designed for current-dependent protection of applications with normal start-up conditions (see "Trip classes") against impermissibly high rises in temperature as a result of overload or phase failure (see "Phase failure protection"). An overload or phase failure causes the motor current to rise above the set rated motor current (see "Setting"). This current rise heats up the bimetal strips within the relay via heating elements which, in turn, operate the auxiliary contacts via a tripping mechanism due to their deflection (see "Auxiliary contacts"). These switch the load off via a contactor. The switch-off time is dependent on the ratio of tripping current to operational current Ie and is stored in the form of a tripping characteristic with long-term stability (see "Tripping characteristics"). The "Tripped" state is signalled by means of a switching position indicator (see "Indication of status"). Resetting takes place manually or automatically (see "Manual and automatic resetting") after a recovery time has elapsed (see "Recovery time"). The 3RU thermal overload relays are electrically and mechanically optimised to the 3RT contactors such that, in addition to individual mounting, they can also be directly mounted onto the contactors to save space (see "Design and mounting"). The main and auxiliary circuits can be connected in various ways (see "Connection"), including the use of Cage Clamp terminals. When the overload relay has been connected, it can be tested for correct functioning using a TEST slide (see "TEST function"). In addition to the TEST function, the 3RU thermal overload relay is equipped with a STOP function (see "STOP function"). For a wide variety of application possibilities for the 3RU thermal overload relay, please refer to the sections "Application", "Ambient conditions", “Overload relays in WYE-delta combinations" and "Operation with frequency converters". Connection for mounting onto contactors: Optimally adapted in electrical, mechanical and design terms to the contactors. The overload relay can be connected directly to these contactor using these pins. Stand-alone installation is possible as an alternative (in conjunction with a terminal bracket for stand-alone installation). Overload relays in WYE-delta combinations When overload relays are used in WYE-delta combinations, it is important to note that only 1/√3 of the motor current flows through the mains contactor. An overload relay mounted on the main contactor must be set to 0.58 times the motor current. A second overload relay must be mounted on the star contactor if your load is also to be optimally protected in WYE operation. The WYE current is 1/3 of the rated motor current. The relevant relay must be set to this current. Selector switch for manual/automatic RESET and RESET button: Control circuit An additional power supply is not required for operation of the 3RU thermal overload relays. A sealable transparent cover can be optionally mounted (accessory). It secures the motor current setting against adjustment. Ambient conditions The 3RU thermal overload relays are temperature compensating according to IEC 60 9474-1/DIN VDE 0660 Part 102 in the temperature range –20 °C to +60 °C. For temperatures from +60 °C to +80 °C, the upper setting value of the setting range must be reduced by a specific factor as given in the table below. Ambient temperature in °C Reduction factor for the upper setting value +60 1.0 +65 0.94 +70 0.87 +75 0.81 +80 0.73 With this switch you can choose between manual and automatic RESET. A device set to manual RESET can be reset locally by pressing the RESET button. A remote RESET is possible using the RESET modules (accessories), which are independent of size. Switch position indicator and TEST function of the wiring: Indicates a trip and enables the wiring test. Motor current setting: Setting the device to the rated motor current is easy with the large rotary knob. STOP button: If the STOP button is pressed, the NC contact is opened. This switches off the contactor downstream. The NC contact is closed again when the button is released. Supply terminals: Depending on the device version, the terminals for screw, spring-type or ring lug terminal connection are configured for the main and auxiliary circuit. 3RU21 26-4FB00 thermal overload relays Trip classes The 3RU thermal overload relay is available for normal startup conditions in CLASS 10. For further details about trip classes, see "Tripping characteristics". Tripping characteristics The tripping characteristics show the relationship between the tripping time and the tripping current as a multiple of the operational current Ie and are specified for symmetrical three-pole and two-pole loading from cold. The smallest current at which tripping occurs is called the limiting tripping current. In accordance with IEC 60 947-4-1/ DIN VDE 0660 Part 102, this must lie within certain specified limits. The limits of the limiting tripping current lie, in the case of the 3RU11 thermal overload re- lay for symmetrical three-pole loading between 105 % and 120 % of the operational current. Starting from the limiting tripping current, the tripping characteristic moves on to larger tripping currents based on the characteristics of the so-called trip classes (CLASS 10, CLASS 20 etc.). The trip classes describe time-intervals within which the overload relay must trip with 7.2 times the operational current Ie for symmetrical three-pole loading from cold. The tripping times are: CLASS Tripping times 10A 2 s to 10 s 10 4 s to 10 s 20 6 s to 20 s 30 9 s to 30 s Siemens Industry, Inc. Industrial Controls Catalog Overload Relays SIRIUS Thermal Overload Relays 3RU11, 3RU21 up to 100 A, CLASS 10 Description TEST function Correct functioning of the ready 3RU thermal overload relay can be tested with the TEST slide. The slide is operated to simulate tripping of the relay. During this simulation, the NC contact (95-96) is opened and the NO contact (9798) is closed whereby the overload relay checks that the auxiliary circuit is wired correctly. When the 3RU thermal overload relay is set to Automatic RESET, an automatic reset takes place when the TEST slide is released. The relay must be reset using the RESET button when it is set to Manual RESET. This is the schematic representation of a characteristic. The characteristics of the individual 3RU thermal overload relays can be requested from Technical Assistance at the e-mail address: [email protected] Tripping time 10 000 100 min 60 40 ANSB00288 5000 s 2000 1000 10 500 5 200 2 1 100 3-pole loading 50 20 10 2-pole loading 5 2 1 0,6 0,8 1 2 3 4 The tripping characteristic of a three-pole 3RU thermal overload relay (see characteristic for symmetrical three-pole loading from cold) is valid when all three bimetal strips are loaded with the same current simultaneously. If, however, only two bimetal strips are heated as a result of phase failure, these two strips would have to provide the force necessary for operating the release mechanism and, if no additional measures were implemented, they would require a longer tripping time or a higher current. These increased current levels over long periods usually result in damage to the consumer. To prevent damage, the 3RU thermal overload relay features phase failure sensitivity which, thanks to an appropriate mechanical mechanism, results in accelerated tripping according to the characteristic for two-pole loading from cold. In contrast to a load in the cold state, a load at operating temperature has a lower heat reserve. This fact affects the 3RU thermal overload relay in that following an extended period of loading at operational current Ie, the tripping time reduces by about a quarter. Phase failure protection The 3RU thermal overload relays feature phase failure protection (see "Tripping characteristics") for the purpose of minimizing the heating of the load during single-phase operation as a result of phase failure. Siemens Industry, Inc. Industrial Controls Catalog 6 8 10 15 20 30 40 A 60 80 x Current n Setting The 3RU thermal overload relay is adjusted to the rated motor current using a rotary knob. The scale of the rotary knob is calibrated in Amperes. Manual and automatic resetting It is possible to switch between manual resetting and automatic resetting by depressing and rotating the blue button (RESET button). When manual resetting is selected, a reset can be performed directly on the device by pressing the RESET button. Remote resetting can be implemented by using the mechanical and electrical RESET modules from the range of accessories (see "Accessories"). When the blue button is set to Automatic RESET, the relay will be reset automatically. A reset is not possible until the recovery time has elapsed (see "Recovery time"). Recovery time After tripping due to an overload, it takes a certain length of time for the bimetal strips of the 3RU thermal overload relays to cool down. The relay can only be reset once it has cooled down. This time (recovery time) is dependent on the tripping characteristic and the level of the tripping current. After tripping due to overload, the recovery time allows the load to cool down. STOP function When the STOP button is pressed, the NC contact is opened and the series-connected contactor and therefore the load is switched Off. The load is reconnected via the contactor when the STOP button is released. Status indication The current status of the 3RU thermal overload relay is indicated by the position of the marking on the "TEST function/switching position indicator" slide. The marking on the slide is on the left at the "O" mark following a trip due to overload or phase failure and at the "I" mark otherwise. Auxiliary contacts The 3RU thermal overload relay is equipped with an NO contact for the tripped signal and an NC contact for switching off the contactor. Connection All the 3RU thermal overload relays have screw terminals for the main and auxiliary circuits. Once the box terminals have been removed from the main conductor connections of the overload relays of size S3, it is possible to connect busbars. Alternatively the devices are available with either spring loaded or with ring lug terminals on both the control and the main terminals. For details of various connection possibilities, see the "Technical data" and "Selection and ordering data". Design and mounting The 3RU thermal overload relays are suitable for direct mounting on the 3RT contactors. They can also be mounted as single units if the appropriate adapters are used. For details of the mounting possibilities, see the "Selection and ordering data" and the "Technical data". Operation with frequency converters The 3RU thermal overload relays are suitable for operation with frequency converters. Depending on the frequency of the converter, a current higher than the motor current may have to be set due to the occurrence of eddy currents and skin effects. Environmental considerations The devices are manufactured taking environmental considerations into account and comprise environmentally-friendly and recyclable materials. Specifications The 3RU thermal overload relays comply with the requirements of: • IEC 60 947-1/ DIN VDE 0660 Part 100 • IEC 60 947-4-1/ DIN VDE 0660 Part 102 • IEC 60 947-5-1/ DIN VDE 0660 Part 200 • IEC 60801-2, -3, -4, -5 and • UL 508/CSA C 22.2.

Siemens Industry, Inc. Industrial Controls Catalog 3/17 Overload Relays • Revised • 04/20/15 3RB2 / 3RB3 Solid-State Overload Relays 3RB20, 3RB21, 3RB30, 3RB31 up to 630A for standard applications SIRIUS Overview The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable materials. They comply with important worldwide standards and approvals. Application Industries The 3RB2 / 3RB3 solid-state over load relays are suitable for customers from all industries who want to provide optimum inverse-time delayed protection of their electrical loads (e.g. motors) under normal and heavy starting conditions (CLASS 5 to CLASS 30), minimize project completion times, inventories and power consumption, and optimize plant availability and maintenance management. Application Connection for mounting onto contactors: Optimally adapted in electrical, mechanical and design terms to the contactors. The overload relay can be connected directly to these contactor using these pins. Stand-alone installation is possible as an alternative (in conjunction with a terminal bracket for stand-alone installation). Selector switch for manual/automatic RESET and RESET button: With this switch you can choose between manual and automatic RESET. A device set to manual RESET can be reset locally by pressing the RESET button. On the 3RB21 a solid-state remote is integrated into the unit. Switch position indicator and TEST function of the wiring: Indicates a trip and enables the wiring test. Solid state test: Enables a test of all important device components and functions. Motor current setting: Setting the device to the rated motor current is easy with the large rotary knob. Trip class setting/internal ground-fault detection (3RB21 only): Using the rotary switch you can set the required trip class and activate the internal ground-fault detection dependent on the starting conditions. Connecting terminals (removable terminal block for auxiliary circuits): The generously sized terminals permit connection of two conductors auxiliary circuit can be connected with screw-type terminals or with spring-loaded terminals. The 3RB and 3RB solid-state overload relays up to 630 A with internal power supply have been designed for inverse-time delayed protection of loads with normal and heavy starting (see Function) against excessive temperature rise due to overload, phase unbalance or phase failure. An overload, phase unbalance or phase failure result in an increase of the motor current beyond the set motor rated current. This current rise is detected by the current transformers integrated into the devices and evaluated by corresponding solid-state circuits which then output a pulse to the auxiliary contacts. The auxiliary contacts then switch off the load by means of the contactors control circuit. The break time depends on the ratio between the tripping current and set current Ie and is stored in the form of a long-term stable tripping characteristic (see Characteristic Curves). In addition to inverse-time delayed protection of loads against excessive temperature rise due to overload, phase unbalance and phase failure, the 3RB21/31 solid-state overload relays also allow internal ground-fault detection (not possible in conjunction with wye-delta assemblies). This provides protection of loads against high-resistance short-circuits due to damage to the insulation material, moisture, condensed water etc. The "tripped" status is signaled by means of a switch position indicator (see Function). Resetting takes place either manually or automatically after the recovery time has elapsed (see Function). 3/18 The 3RB2 / 3RB3 solid-state overload relays have been designed for the protection of three-phase motors in sinusoidal 50/60 Hz voltage networks. The relays are not suitable for the protection of single-phase AC or DC loads. The 3RU thermal overload relay or the 3RB22/3RB23 solidstate overload relay can be used for single-phase AC loads. For DC loads the 3RU thermal overload relays are available. Ambient conditions The devices are insensitive to external influences such as shocks, corrosive environments, ageing and temperature changes. For the temperature range from –25 C to +60 °C, the 3RB2 / 3RB3 solid-state overload relays compensate the temperature according to IEC 60947-4-1. The 3RB2 / 3RB3 solid-state overload relays are suitable for the overload protection of explosion-proof motors with "increased safety" type of protection EEx e according to ATEX guideline 94/9/EC. The relays meet the requirements of EN 60079-7 (Electrical apparatus for potentially explosive atmospheres – Increased safety "e").

Mounting options The 3RB2 / 3RB3 solid-state overload relays are suitable for direct and space-saving mounting onto 3RT1 / 3RT2 contactors and 3RW30/3RW31 soft starters as well as for stand-alone installation. For more information on the mounting options, please see Technical Specifications and Selection and . Ordering Data Connection technique Main circuit All sizes of the 3RB2 / 3RB3 solid-state overload relays can be connected with screw-type terminals. As an alternative for sizes S3 to S10/S12, the main circuits can be connected via the Busbar. Sizes S2 to S6 of the 3RB20/3RB21 relays are also available with a straight-through transformer. In this case, the cables of the main circuit are routed directly through the feed-through openings of the relay to the contactor terminals. Overload relays in contactor assemblies for Wye-Delta starting When overload relays are used in combination with contactor assemblies for Wye-Delta starting it must be noted that only 0.58 times the motor current flows through the line contactor. An overload relay mounted onto the line contactor must be set to 0.58 times the motor current. When 3RB21 / 31 solid-state overload relays are used in combination with contactor assemblies for Wye-Delta starting, the internal ground-fault detection must not be activated. Operation with frequency converter The 3RB2 / 3RB3 solid-state overload relays are suitable for frequencies of 50/60 Hz and the associated harmonics. This permits the 3RB2 / 3RB3 overload relays to be used on the incoming side of the frequency converter. If motor protection is required on the outgoing side of the frequency converter, the 3RN thermistor motor protection devices or the 3RU thermal overload relays are available for this purpose. Auxiliary circuit Connection of the auxiliary circuit (removable terminal block) is possible with either screw terminals or spring-loaded terminals. For more information on the connection options, see Technical Specifications and Selection and Ordering Data. Siemens Industry, Inc. Industrial Controls Catalog 3/19 Overload Relays SIRIUS 3RB2 / 3RB3 Solid-State Overload Relays 3RB20, 3RB21, 3RB30, 3RB31 up to 630A for standard applications Function Basic functions Recovery time The 3RB2 / 3RB3 solid-state overload relays are designed for: • Inverse-time delayed protection of loads from overloading • Inverse-time delayed protection of loads from phase unbalance • Inverse-time delayed protection of loads from phase failure • Protection of loads from high-resistance short-circuits (internal ground-fault detection only with 3RB21 / 31). With the 3RB2 / 3RB3 solid-state overload relays the recovery time after inverse-time delayed tripping is between 0.5 and 3 minutes depending on the preloading when automatic RESET is set. These recovery times allow the load (e.g. motor) to cool down. Control circuit The 3RB2 / 3RB3 solid-state overload relays have an internal power supply, i.e. no additional supply voltage is required. Short-circuit protection Fuses or motor starter protectors must be used for short-circuit protection. For assignments of the corresponding short-circuit protection devices to the 3RB2 / 3RB3 solid-state overload relays with/without contactor see Technical Specifications and Selection and Ordering Data. If the button is set to manual RESET, the 3RB2 / 3RB3 devices can be reset immediately after inverse-time delayed tripping. After a ground fault trip the 3RB21 / 31 solid-state overload relays (with ground-fault detection activated) can be reset immediately without a recovery time regardless of the reset mode set. TEST function With motor current flowing, the TEST button can be used to check whether the relay is working correctly (device/solid-state TEST). Current measurement, motor model and trip unit are tested. If these components are OK, the device is tripped in accordance with the table below. If there is an error, no tripping takes place. Trip classes Trip class The 3RB20 / 30 solid-state overload relays are available for normal starting conditions with trip CLASS 10 or for heavy starting conditions with trip CLASS 20 (fixed setting in each case). Required loading with the Tripping within rated current prior to pressing the test button CLASS 5 2 min 8s CLASS 10 4 min 15 s 30 s The 3RB21 / 31 solid-state overload relays are suitable for normal CLASS 20 8 min and heavy starting. The required trip class (CLASS 5, 10, 20 or 12 min 45 s CLASS 30 30) can be adjusted by means of a rotary knob depending on the Note: The test button must be kept pressed throughout the test. current starting condition. For details of the trip classes see Characteristic Curves. Phase failure protection The 3RB2 / 3RB3 solid-state overload relays are fitted with phase failure protection (see Characteristic Curves) in order to minimize temperature rise of the load during single-phase operation. Phase failure protection is not effective for loads with starconnection and a grounded neutral point or a neutral point which is connected to a neutral conductor. Setting The 3RB2 / 3RB3 solid-state overload relays are set to the motor rated current by means of a rotary knob. The scale of the rotary knob is shown in amps. Testing of the auxiliary contacts and the control current wiring is possible with the switch position indicator slide. Actuating the slide simulates tripping of the relay. During this simulation the NC contact (95-96) is opened and the NO contact (97-98) is closed. This tests whether the auxiliary circuit has been correctly wired. After a test trip the relay is reset by pressing the RESET button. Self-monitoring The 3RB2 / 3RB3 solid-state overload relays have a self-monitoring feature, i.e. the devices constantly monitor their own basic functions and trip if an internal fault is detected. Display of operating status With the 3RB21 / 31 solid-state overload relay it is also possible to select the trip class (CLASS 5, 10, 20 or 30) using a second rotary knob and to switch the internal ground-fault detection on and off. The respective operating status of the 3RB2 / 3RB3 solid-state overload relays is displayed by means of the position of the marking on the switch position indicator slide. After tripping due to overload, phase failure, phase unbalance or ground fault (ground fault detection possible only with 3RB21 / 31) the marking on the slide is to the left on the "O" mark, otherwise it is on the "I" mark. Manual and automatic reset Auxiliary contacts In the case of the 3RB2 / 3RB3 solid-state overload relays, a slide switch can be used to choose between automatic and manual resetting. The 3RB2 / 3RB3 solid-state overload relays are fitted with an NO contact for the "tripped" signal, and an NC contact for switching off the contactor. If manual reset is set, a reset can be carried out directly on the device after a trip by pressing the blue RESET button. Resetting is possible in combination with the mechanical reset options from the accessories range (see Accessories). As an alternative to the mechanical RESET options, the 3RB21 / 31 solid-state overload relays are equipped with an electrical remote RESET which may be utilized by applying a voltage of 24 V DC to the terminals A3 and A4. If the slide switch is set to automatic RESET, the relay is reset automatically. The time between tripping and resetting is determined by the recovery time. 3/20 Siemens Industry, Inc.

Industrial Controls Catalog Overload Relays SIRIUS 3RB2 / 3RB3 Solid-State Overload Relays 3RB20, 3RB21, 3RB30, 3RB31 up to 630A for standard applications Characteristic curves The smallest current used for tripping is called the minimum tripping current. According to IEC 60947-4-1, this current must be within specified limits. The limits of the total tripping current for the 3RB20/3RB21 solid-state overload relays for symmetrical three-pole loads are between 105 % and 120 % of the set current. Tripping characteristics for 3-pole loads 1000 800 600 Tripping time The tripping characteristics show the relationship between the tripping time and tripping current as multiples of the set current Ie and are given for symmetrical three-pole and two-pole loads from the cold state. 3…5s CLASS 10 5 … 10 s CLASS 20 10 … 20 s CLASS 30 20 … 30 s The tripping characteristic for a three-pole overload relay from the cold state (see illustration 1) only apply if all three phases are simultaneously loaded with the same current. In the event of a phase failure the 3RB20/3RB21 solid-state overload relays switch off the contactor more quickly in order to minimize heating of the load in accordance with the tripping characteristic for twopole loads from the cold state (see illustration 2). With phase unbalance the devices switch off depending on the reason for the unbalance between the two characteristic curves. Compared with a cold load, a load at operating temperature obviously has a lower temperature reserve. The tripping time of the 3RB2/3RB3 solid-state overload relays is reduced therefore to about 30 % when loaded with the set current Ie for an extended period. 20 CLASS 30 10 8 6 CLASS 20 CLASS 10 4 CLASS 5 2 1 0,6 1 2 4 6 Tripping current 8 10× e Illustration 1 Tripping characteristics for 2-pole loads 1000 800 600 Tripping time Tripping time 200 40 The tripping times according to IEC 60947-4-1, tolerance band E, are as follows for: CLASS 5 400 s 100 80 60 The tripping characteristic starts with the minimum tripping current and continues with higher tripping currents based on the characteristics of the so-called trip classes (CLASS 10, CLASS 20 etc.).

Industrial Controls Catalog 3/31 Overload Relays 3RB2 Solid-State Overload Relays 3RB22, 3RB23 for high-feature applications Overview The modular, solid-state overload relays with external power supply type 3RB22 (with monostable auxiliary contacts) and type 3RB23 (with bistable auxiliary contacts) up to 630 A (up to 820 A possible with a series transformer) have been designed for inverse-time delayed protection of loads with normal and heavy starting (see Function) against excessive temperature rises due to overload, phase unbalance or phase failure. An overload, phase unbalance or phase failure result in an increase of the motor current beyond the set motor rated current. This current rise is detected by means of a current measuring module and electronically evaluated by a special evaluation module which is connected to it. The evaluation electronics sends a signal to the auxiliary contacts. The auxiliary contacts then switch off the load by means of the contactors control circuit. The break time depends on the ratio between the tripping current and set current Ie and is stored in the form of a long-term stable tripping characteristic (see Characteristic Curves). The "tripped" status is signaled by means of a continuous red "Overload" LED. 3RB22/3RB23 evaluation module (1)Green "Ready" LED: A continuous green light signals that the device is working correctly. (2)Red "Ground Fault" LED: A continuous red light signals a ground fault. (3)Red "Thermistor" LED: A continuous red light signals an active thermistor trip. (4)Red "Overload" LED: A continuous red light signals an active overload trip; a flickering red light signals an imminent trip (overload warning). (5)Motor current and trip class adjustment: Setting the device to the motor current and to the required trip class dependent on the starting conditions is easy with the two rotary knobs. (6)Selector switch for manual/automatic RESET: With this switch you can choose between manual and automatic RESET. (7)Test/RESET button: Enables testing of all important device components and functions, plus resetting of the device after a trip when manual RESET is selected. (8)Connecting terminals (removable terminal block): The generously sized terminals permit connection of two conductors with different cross-sections for the auxiliary, control and sensor circuits. Connection is possible with screw-type terminals and alternatively with spring-loaded terminals. (9)3RB29 85 function expansion module: Enables more functions to be added, e.g. internal ground fault detection and/or an analog output with corresponding signals. The LED indicates imminent tripping of the relay due to overload, phase unbalance or phase failure by flickering when the limit current has been violated. This warning can also be used as a signal through auxiliary contacts. In addition to the described inverse-time delayed protection of loads against excessive temperature rise, the 3RB22/3RB23 solid-state overload relays also allow direct temperature monitoring of the motor windings (full motor protection) by failsafe connection of a PTC sensor circuit. With this temperature-dependent protection, the loads can be protected against overheating caused indirectly by reduced coolant flow, for example, which cannot be detected by means of the current alone. In the event of overheating, the devices signal the contactor to switch off, and thus the load, by means of the auxiliary contacts. The "tripped" status is signaled by means of a continuous red "Thermistor" LED. To also protect the loads against high-resistance short-circuits due to damage to the insulation, humidity, condensed water, etc., the 3RB22/3RB23 solid-state overload relays offer the possibility of internal ground fault monitoring in conjunction with a function expansion module; not possible in conjunction with a contactor assembly for Wye-Delta starting). In the event of a ground fault the 3RB22/3RB23 relays trip instantaneously. The "tripped" status is signaled by means of a red "Ground Fault" LED. Signaling through auxiliary contacts is also possible. After tripping due to overload, phase unbalance, phase failure, thermistor tripping or ground fault, the relay may be reset manually or automatically after the recovery time has elapsed (see Function). In conjunction with a function expansion module the motor current measured by the microprocessor can be output in the form of an analog signal 4 ... 20 mA DC for operating rotary coil instruments or for feeding into analog inputs of programmable logic controllers. With an additional AS-Interface analog module the current values can also be transferred over the AS-i bus system. The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable materials. They comply with important worldwide standards and approvals. 3RB29 06 current measuring module 3/32 Siemens Industry, Inc.

Industrial Controls Catalog 3/35 Overload Relays 3RB2 Solid-State Overload Relays 3RB22, 3RB23 for high-feature applications Design Function Device concept Basic functions The 3RB22/3RB23 solid-state overload relays are based on a modular device concept. Each device always comprises an evaluation module, which is independent of the motor current, and a current measuring module, which is dependent on the motor current. The two modules are electrically interconnected by a connection cable through the system interface. The 3RB22/3RB23 solid-state overload relays are designed for: • Inverse-time delayed protection of loads from overloading • Inverse-time delayed protection of loads from phase unbalance • Inverse-time delayed protection of loads from phase failure • Temperature-dependent protection of loads by connecting a PTC sensor circuit • Protection of loads from high-resistance short-circuits (internal ground-fault detection; detection of fault currents > 30 % of the set current Ie) • Output of an overload warning • Output of an analog signal 4 to 20 mA DC as image of the flowing motor current The basic functionality of the evaluation module can be optionally expanded with corresponding function expansion modules. The function expansion modules are integrated in the evaluation module for this purpose through a simple plug connection. Mounting options Current measuring modules The current measuring modules size S00/S0 and S2/S3 are designed for stand-alone installation. By contrast, the current measuring modules size S6 and S10/S12 are suitable for stand-alone installation or direct mounting. The basic functions of the evaluation modules in conjunction with function expansion modules are listed in the following table: Function expansion module Basic functions The evaluation modules can be mounted either on the current measuring module (only sizes S00/S0 and S2/S3) or separately.

In this case, the cables of the main circuit are routed directly through the feed-through openings of the relay to the contactor terminals. For sizes S6 and S10/S12, the main circuit can be connected with the help of the Busbar. In conjunction with the corresponding box terminals, screw terminals are also available. Auxiliary circuit (evaluation module) Connection of the auxiliary circuit (removable terminal block) is possible with either screw terminals or spring-loaded terminals. Overload relays in contactor assemblies for Wye-Delta starting When overload relays are used in combination with contactor assemblies for Wye-Delta starting it must be noted that only 0.58 times the motor current flows through the line contactor. An overload relay mounted onto the line contactor must be set to 0.58 times the motor current. When 3RB22/3RB23 solid-state overload relays are used in combination with contactor assemblies for Wye-Delta starting, the function expansion modules for internal ground-fault detection must not be used. Operation with frequency converter The 3RB22/3RB23 solid-state overload relays are suitable for frequencies of 50/60 Hz and the associated harmonics. This permits the 3RB22/3RB23 overload relays to be used on the incoming side of the frequency converter. If motor protection is required on the outgoing side of the frequency converter, the 3RN thermistor motor protection devices or the 3RU11 thermal overload relays are available for this purpose. Control circuit The 3RB22/3RB23 solid-state overload relays require an external power supply (24–240 V AC/DC), i.e. an additional supply voltage is necessary. Short-circuit protection Fuses or motor starter protectors must be used for short-circuit protection. For assignments of the corresponding short-circuit protection devices to the 3RB22/3RB23 solid-state overload relays with/without contactor see Technical Specifications and Selection and Ordering Data. Trip classes The 3RB22/3RB23 solid-state overload relays are suitable for normal and heavy starting. The required trip class (CLASS 5, 10, 20 or 30) can be adjusted by means of a rotary knob depending on the current starting condition. For details of the trip classes see Characteristic Curves. 3/36 Siemens Industry, Inc. Industrial Controls Catalog Overload Relays 3RB2 Solid-State Overload Relays 3RB22, 3RB23 for high-feature applications Phase failure protection TEST function The 3RB22/3RB23 solid-state overload relays are fitted with phase failure protection (see Characteristic Curves) in order to minimize temperature rises of the load during single-phase operation. The combined TEST/RESET button can be used to check whether the relay is working correctly. The test can be aborted at any time by letting go of the TEST/RESET button. Setting The 3RB22/3RB23 solid-state overload relays are set to the motor rated current by means of two rotary knobs. • The upper rotary knob (CLASS/Iemax) is divided into 4 ranges: 1 A, 10 A, 100 A and 1000 A. The zone must be selected which corresponds to the rated motor current and the current measuring module to be used with it. With the range selected the required trip class (CLASS 5, 10, 20 or 30) can be determined. • The lower rotary knob with percent scale (10 % ... 100 %) is then used to set the rated motor current in percent of the range selected with the upper rotary button. LEDs, the device configuration (this depends on which expansion module is plugged in) and the device hardware are tested while the button is kept pressed for 6 seconds. Simultaneously and for another 18 seconds a direct current proportional in size to the maximum phase of the main current is fed in at the terminals I(+) and I(-). By comparing the analog signal, which is to be measured, with the main current, the accuracy of the current measurement can be determined. In this case 4 mA corresponds to 0 % and 20 mA to 125 % of the set current. After 24 seconds the auxiliary contacts are switched and the feeder switch off as the result, bringing the test to an end. After a test trip a faultless relay is reset by pressing the TEST/RESET button. If a hardware fault is detected, the device trips and cannot be reset. Example • Rating of induction motor = 45 kW (50 Hz, 400 V AC) • Rated motor current = 80 A • Required trip class = CLASS 20 • Selected transformer: 10 to 100 A Self-monitoring Solution • Step 1: Use the upper rotary knob (CLASS) to select the 100 A range • Step 2: Within the 100 A range set the trip class CLASS 20 • Step 3: Set the lower rotary knob to 80 % (= 0.8) of 100 A × 0.8 = 80 A. The particular operating status of the 3RB22/3RB23 solid-state overload relays is displayed by means of four LEDs: • Green "Ready" LED: A continuous green light signals that the overload relay is ready for operation. The 3RB22/3RB23 overload relays are not ready (LED "OFF") if there is no control supply voltage or if the function test was negative. • Red "Ground fault" LED: A continuous red light signals a ground fault. • Red "Thermistor" LED: A continuous red light signals a temperature-dependent trip. • Red "Overload" LED: A continuous red light signals an inversetime delayed trip; a flickering red light signals an imminent inverse-time delayed trip (overload warning). If the current which is set on the evaluation module does not correspond to the current range of the connected current transformer, an error will result. Manual and automatic reset In the case of the 3RB22/3RB23 solid-state overload relays, a slide switch can be used to choose between automatic and manual resetting. If manual reset is set, a reset can be carried out directly on the device after a trip by pressing the blue TEST/RESET button. A remote RESET can be carried out electrically by jumpering the terminals Y1 and Y2. If the slide switch is set to automatic RESET, the relay is reset automatically. The time between tripping and resetting is determined by the recovery time. Recovery time With the 3RB22/3RB23 solid-state overload relays the recovery time after inverse-time delayed tripping is approx. 3 minutes regardless of the selected reset mode. The recovery time allows the load to cool down. However, in the event of temperature-dependent tripping by means of a connected PTC thermistor sensor circuit, the device can only be manually or automatically reset once the winding temperature at the installation location of the PTC thermistor has fallen 5 Kelvin below its response temperature. After a ground fault trip the 3RB22/3RB23 solid-state overload relay trips can be reset immediately without a recovery time. Siemens Industry, Inc. Industrial Controls Catalog The 3RB22/3RB23 solid-state overload relays have a self-monitoring feature, i.e. the devices constantly monitor their own basic functions and trip if an internal fault is detected. Display of the operating status Auxiliary contacts The 3RB22/3RB23 solid-state overload relays have two outputs, each with one NO contact and one NC contact. Their basic assignment/function may be influenced by function expansion modules. The 3RB22 and 3RB23 differ with respect to the tripping characteristics of their auxiliary contacts – monostable or bistable: The monostable 3RB22 solid-state overload relays will enter the "tripped" state if the control supply voltage fails (> 200 ms), and return to the original state they were in before the control supply voltage failed when the voltage returns. These devices are therefore especially suited for plants in which the control voltage is not strictly monitored. The bistable 3RB23 overload relays do not change their "tripped" or "not tripped" status if the control voltage fails. The auxiliary contacts only switch over in the event of an overload and if the supply voltage is present. These devices are therefore especially suited for plants in which the control voltage is monitored separately. Response if the control supply voltage fails If the control supply voltage fails for more than 0.2 s, the output relays respond differently depending on the version: Monostable or bistable. 3/37 Overload Relays 3RB2 Solid-State Overload Relays 3RB22, 3RB23 for high-feature applications Response of the output relays in the event of Monostable Bistable 3RB22 3RB23 Failure of the control supply voltage The device trips No change of the switching status of the auxiliary contacts Return of the control The device resets supply voltage without previous tripping No change of the switching status of the auxiliary contacts Return of the control supply voltage after previous tripping The device remains tripped The device remains tripped Reset: • For overload tripping, after 3 minutes • For thermistor tripping, after the temperature has fallen 5 K below the response temperature • For ground-fault tripping, immediately Reset: • For overload tripping, after 3 minutes • For thermistor tripping, after the temperature has fallen 5 K below the response temperature • For ground-fault tripping, immediately Monostable and bistable responses of the output relays 3/38 Siemens Industry, Inc.

Siemens Industry, Inc. Industrial Controls Catalog 3/43 Overload Relays 3RB2 Solid-State Overload Relays 3RB22, 3RB23 for standard applications Characteristic curves The smallest current used for tripping is called the minimum tripping current. According to IEC 60947-4-1, this current must be within specified limits. The limits of the minimum tripping current for the 3RB22/3RB23 solid-state overload relays for symmetrical three-pole loads are between 105 % and 120 % of the set current. Tripping characteristics for 3-pole loads 1000 800 600 Tripping time The tripping characteristics show the relationship between the tripping time and tripping current as multiples of the set current Ie and are given for symmetrical three-pole and two-pole loads from the cold state. 3…5s CLASS 10 5 … 10 s CLASS 20 10 … 20 s CLASS 30 20 … 30 s The tripping characteristic for a three-pole overload relay from the cold state (see illustration 1) only apply if all three phases are simultaneously loaded with the same current. In the event of a phase failure or a current unbalance of more than 40 %, the 3RB22/3RB23 solid-state overload relays switch off the contactor more quickly in order to minimize heating of the load in accordance with the tripping characteristic for two-pole loads from the cold state (see illustration 2). Compared with a cold load, a load at operating temperature obviously has a lower temperature reserve. The tripping time of the 3RB22/3RB23 solid-state overload relays are reduced therefore to about 30 % when loaded with the set current Ie for an extended period. 20 CLASS 30 10 8 6 CLASS 20 CLASS 10 4 CLASS 5 2 1 0,6 1 2 4 6 Tripping current 8 10× e Illustration 1 Tripping characteristics for 2-pole loads 1000 800 600 Tripping time Tripping time 200 40 The tripping times according to IEC 60947-4-1, tolerance band E, are as follows for: CLASS 5 400 s 100 80 60 The tripping characteristic starts with the minimum tripping current and continues with higher tripping currents based on the characteristics of the so-called trip classes (CLASS 10, CLASS 20 etc.). The trip classes describe time intervals within which the overload relays have to trip with 7.2 times the set current Ie from the cold state for symmetrical three-pole loads.

The "tripped" status is signaled by means of a continuously illuminated red "OVERLOAD" LED and also reported as a group fault via IO-Link. The LED indicates imminent tripping of the relay due to overload, phase unbalance or phase failure by flickering when the limit current has been violated. This warning can also be reported to the higher-level PLC via IO-Link at the 3RB24 overload relay. Green LED "DEVICE/IO-Link: A continuous green light signals that the device is working correctly, a green flickering light signals the communication through IO-Link. Red LED "GND FAULT": A continuous red light signals an active ground-fault trip. 7 Red LED "THERMISTOR": A continuous red light signals an active thermistor trip. Red LED "OVERLOAD": A continuous red light signals an active overload trip; a flickering red light signals an imminent trip (overload warning). Motor current and trip class setting: Setting the device to the motor current and to the required trip class dependent on the start-up conditions is easy with the two rotary switches. Selector switch for manual/automatic RESET: With this switch you can choose between manual and automatic RESET. Test/RESET button: Enables testing of all important device components and functions, plus resetting of the device after a trip when manual RESET is selected. Connecting terminals (removable terminal block): The generously sized terminals permit connection of two conductors with different cross-sections for the auxiliary, control and sensor circuits. Connection is possible with screw connection and alternatively with spring-type connection. Plug-in point for operator panel: enables connection of the 3RA69 35-0A operator panel. SIRIUS 3RB24 evaluation module The modular electronic overload relay 3RB24, which is powered via IO-Link (with monostable auxiliary contacts) up to 630 A (up to 820 A possible with a series transformer) have been designed for inverse-time delayed protection of loads with normal and heavy starting ("Function" see "Manual for SIRIUS 3RB24 SolidState Overload Relay for IO-Link",) against excessive temperature rises due to overload, phase unbalance or phase failure. It comprises an evaluation unit, a current measuring module and a connecting cable. The evaluation module 3RB24 also offers an motor starter function: The contactors, which are connected via the auxiliary contacts, can also be actuated for operation via IO-Link. In this way, direct, reversing and star-delta starters up to 630 A (or 830 A) can be connected to the controller wirelessly via the IO-Link controller. An overload, phase unbalance or phase failure result in an increase of the motor current beyond the set rated motor current. This current rise is detected by means of the current measuring module (see page 7/134) and electronically evaluated by the evaluation module which is connected to it. The evaluation electronics sends a signal to the auxiliary contacts. The auxiliary contacts then switch off the load by means of a contactor. The 3/52 7/128 Siemens IC 10 · 2012 In addition to the described inverse-time delayed protection of loads against excessive temperature rises, the 3RB24 solidstate overload relays also allow direct temperature monitoring of the motor windings (full motor protection) by connection with broken-wire interlock of a PTC sensor circuit. With this temperature-dependent protection, the loads can be protected against overheating caused indirectly by reduced coolant flow, for example, which cannot be detected by means of the current alone. In the event of overheating, the devices switch off the contactor, and thus the load, by means of the auxiliary contacts. The "tripped" status is signaled by means of a continuously illuminated "THERMISTOR" LED and also reported as a group fault via IO-Link. To the loads against incomplete ground faults due to damage to the insulation, humidity, condensation, etc., to protect the electronic overload relay 3RB24 offer the possibility of internal ground-fault detection (for details see "Manual for SIRIUS 3RB24 Solid-State Overload Relay for IO-Link",, not possible in conjunction with contactor assembly for wye-delta starting). In the event of a ground fault, the 3RB24 relays trip instantaneously. The "tripped" status is signaled by means of a flashing red LED "Ground Fault" and reported at the overload relay 3RB24 as a group fault via IO-Link. The reset after overload, phase unbalance, phase failure, thermistor or ground-fault tripping is performed manually by key on site, via IO-Link or by electrical remote RESET or automatically after the cooling time (motor model) or for thermistor protection after sufficient cooling. Power cuts in devices due to function monitoring (broken wire or short circuit on the thermistor) can only be reset on-site ("Function" see "Manual for SIRIUS 3RB24 Solid-State Overload Relay for IO-Link",). In conjunction with a function expansion module, the motor current measured by the microprocessor can be output in the form of an analog signal DC 4 to 20 mA for operating rotary coil instruments or for feeding into analog inputs of programmable logic controllers. The current values can be transmitted to the higher-level controller via IO-Link. The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable materials. They comply with all important worldwide standards and approvals. Type of protection "increased safety EEx e and explosionproof enclosure EEx d" in accordance with ATEX Directive 94/9/EC The electronic overload relay 3RB24 (monostable) are suitable for the overload protection of explosion-proof motors of types of protection EEx e and EEx d.

Benefits Advantages through energy efficiency y f ic i e n cy c on E ne rg ef according to EN 16001 Realization ation alu g ltin nt ifi n su Id e tio Ev ca IC01_00135 Overview of the energy management process We offer you a unique portfolio for industrial energy management, using an energy management system that helps to optimally define your energy needs. We split up our industrial energy management into three phases – Identification, Evaluation and Realization – and we support you with the appropriate hardware and software solutions in every process phase. The innovative products of the SIRIUS industrial controls portfolio can also make a substantial contribution to a plant's energy efficiency (see www.siemens.com/sirius/energysaving). 3RB24 solid-state overload relays for IO-Link contribute to energy efficiency throughout the plant as follows: • Transmission of current values • Reduced inherent power loss • Less heating of the control cabinet • Smaller control cabinet air conditioners can be used Application Industries The 3RB24 solid-state overload relays are suitable for customers from all industries who want to guarantee optimum inverse-time delayed and temperature-dependent protection of their electrical loads (e.g. motors) under normal and heavy starting conditions (CLASS 5 to 30), minimize project completion times, inventories and energy consumption, and optimize plant availability and maintenance management. If single-phase AC motors are to be protected by the 3RB24 solid-state overload relays, the main current paths of the current measuring modules must be series-connected ("Schematics" see "Manual for SIRIUS 3RB24 Solid-State Overload Relay for IO-Link",). Ambient conditions Application The devices are insensitive to external influences such as shocks, corrosive ambient conditions, ageing and temperature fluctuations. The 3RB24 solid-state overload relays have been designed for the protection of three-phase asynchronous and single-phase AC motors. For the temperature range from –25 C to +60 °C, the 3RB24 solid-state overload relays compensate the temperature in accordance with IEC 60947-4-1. In addition to protection function, these devices can be used together with contactors as direct or reversing starters (star-delta (wye-delta) start also possible), which are controlled via IO-Link. This makes it possible to directly control drives via IO-Link from a higher-level controller or on site via the optional hand-held device lamps and also, for example, to return current values directly via IO-Link.

It optimizes the connection between the PLC and the motor starter, increases plant availability and allows significant savings to be made during startup, operation and maintenance of a system. • Ground-fault modules • Temperature modules — 1 2 Two series SIMOCODE pro is structured into two functionally tiered series: • SIMOCODE pro C, as a compact system for direct-on-line starters and reversing starters or the actuation of a circuit breaker • SIMOCODE pro V, as a variable system with all control functions and with the possibility of expanding the inputs, outputs and functions of the system at will using expansion modules Siemens Industry, Inc. Industrial Controls Catalog Available Not available 1)When an operator panel with display and/or a decoupling module is used, more restrictions on the number of expansion modules connectable per basic unit must be observed, see page 3/68. 2)The fail-safe digital module can be used instead of one of the two digital modules. Per feeder each system always comprises one basic unit and one separate current measuring module. The two modules are connected together electrically through the system interface with a connection cable and can be mounted mechanically connected as a unit (one behind the other) or separately (side by side). The motor current to be monitored is decisive only for the choice of the current measuring module. An operator panel for mounting in the control cabinet door is optionally connectable through a second system interface on the basic unit. Both the current measuring module and the operator panel are electrically supplied by the basic unit through the connection cable. More inputs, outputs and functions can be added to basic unit 2 and basic unit 3 by means of optional expansion modules, thus supplementing the inputs and outputs already existing on the basic unit. With the DM-F Local and DM-F PROFIsafe fail-safe digital modules it is also possible to integrate the fail-safe disconnection of motors in the SIMOCODE pro V motor management system. All modules are connected by connection cables. The connection cables are available in various lengths. The maximum distance between the modules (e.g. between the basic unit and the current measuring module) must not exceed 2.5 m. The total length of all the connection cables in a single system may be up to 3 m with basic unit 1. With basic units 2 and 3 the total length for each system interface may be up to 3 m. 3/63 Siemens IC 10 N · 12/2012 10/5 10 When SIMOCODE pro is installed in the control panel, it is the intelligent interface between the higher-level automation system and the motor feeder and includes the following: • Multi-functional, electronic full motor protection which is independent of the automation system • Integrated control functions instead of hardware for the motor control • Detailed operating, service and diagnostics data • Open communication through PROFIBUS DP, PROFINET and OPC UA • Safety relay function for the fail-safe disconnection of motors up to SIL 3 (IEC 61508, IEC 62061) or PL e with Category 4 (EN ISO 13849-1) • SIMOCODE ES is the software package for SIMOCODE pro parameterization, start-up and diagnostics. — SIMOCODE 3UF Motor Management and Control Devices SIMOCODE 3UF Motor Management and Control Devices SIMOCODE pro 3UF7 SIMOCODE pro 3UF7 motor management and control devices General data Order No. scheme Digit of the Order No. 1st - 4th 5th 6th 7th @@@@ @ @ @ SIMOCODE pro motor management system 3UF7 @ @ Type of unit/module 8th – 1 Connection type of the current transformer Example @ @ 13th 0 0 – 0 0 0 – 0 @ Functional version of the unit/module Voltage version 9th 10th 11th 12th @ @ 3UF7 0 1 0 – 1 A B Note: The Order No. scheme is presented here merely for information purposes and for better understanding of the logic behind the order numbers.

Flexible motor control implemented with integrated control functions (instead of comprehensive hardware interlocks) Many predefined motor control functions have already been integrated into SIMOCODE pro, including all necessary logic operations and interlocks: • Overload relays • Direct-on-line and reversing starters • Wye/delta starters (also with direction reversal) • Two speeds, motors with separate windings (pole-changing switch); also with direction reversal • Two speeds, motors with separate Dahlander windings (also with direction reversal) • Positioner actuation • Solenoid valve actuation • Actuation of a circuit breaker • Soft starter actuation (also with direction reversal) These control functions are predefined in SIMOCODE pro and can be freely assigned to the inputs and outputs of the device (including PROFIBUS/PROFINET). These predefined control functions can also be flexibly adapted to each customized configuration of a motor feeder by means of freely configurable logic modules (truth tables, counters, timers, edge evaluation, etc.) and with the help of standard functions (power failure monitoring, emergency start, external faults, etc.), without additional auxiliary relays being necessary in the control circuit. SIMOCODE pro eliminates the need for additional hardware and wiring in the control circuit which results in a high level of standardization of the motor feeder in terms of its design and circuit diagrams.

In the event of a malfunction, a fault can be diagnosed, localized and rectified very quickly – there are no or very short downtimes. SIMOCODE pro has either an integrated PROFIBUS DP interface (SUB-D or terminal connection) or a PROFINET interface (2 x RJ45). Service data • Motor operating hours • Motor stop times • Number of motor starts • Number of overload trips • Interval for mandatory testing of the enabling circuits • Energy consumed • Internal comments stored in the device etc. Diagnostics data • Numerous detailed early warning and fault messages • Internal device fault logging with time stamp • Time stamping of freely selectable status, alarm or fault messages etc. Easy operation and diagnostics Operator panels The operator panel is used to control the motor feeder and can replace all conventional pushbuttons and indicator lights to save space. It makes SIMOCODE pro or the feeder directly operable in the control cabinet. It features all the status LEDs available on the basic unit and externalizes the system interface for simple parameterization or diagnosis on a PC/PG. Operator panels with display As an alternative to the 3UF7 20 standard operator panel for SIMOCODE pro V there is also an operator panel with display: the 3UF7 21 is thus able in addition to indicate current measured values, operational and diagnostics data or status information of the motor feeder at the control cabinet. The pushbuttons of the operator panel can be used to control the motor. Also, when SIMOCODE pro V PROFINET is used it is possible to set parameters such as rated motor current, limit values, etc. directly using the operator panel with display. SIMOCODE pro for PROFIBUS SIMOCODE pro for PROFIBUS supports for example: • Cyclic services (DPV0) and acyclic services (DPV1) • Extensive diagnostics and process alarms • Time stamp with high timing precision (SIMATIC S7) for SIMOCODE pro V • DPV1 communication after the Y-Link SIMOCODE pro for PROFINET SIMOCODE pro for PROFINET supports for example: • Line and ring bus topology thanks to an integrated switch • Media redundancy via MRP protocol • Operating, service and diagnostics data via standard web browser • OPC UA server for open communication with visualization and control system • NTP-synchronized time • Interval function and measured values for energy management via PROFIenergy • Module exchange without PC memory module through proximity detection • Extensive diagnostics and maintenance alarms Notes on safety For connection of an internal system to an external system, suitable protective measures must be taken to ensure safe operation of the plant (including IT security, e. g. network segmentation). More information see www.siemens.com/industrialsecurity. For SIMOCODE pro motor management and control devices with communication function see page 3/69 onwards. Accessories see page 3/73 onwards. Autonomous operation An essential feature of SIMOCODE pro is independent execution of all protection and control functions even if communication with the I&C system breaks down. If the bus or automation system fails, the full functionality of the feeder is ensured or a predefined response can be initiated, e.g. the feeder can be shut down in a controlled manner or certain configured control mechanisms can be performed (e.g. the direction of rotation can be reversed). 3/65 Siemens Industry, Inc.

Applications Protection and control of motors in hazardous areas for types of protection EEx e/d according to ATEX guideline 94/9/EC • With heavy starting (paper, cement, metal and water industries) • In high-availability plants (chemical, oil, raw material processing industries, power plants) Siemens Industry, Inc. Industrial Controls Catalog Safety technology for SIMOCODE pro The safe disconnection of motors, in the process industry in particular, is becoming increasingly important as a result of new and revised standards and requirements in the safety technology field. With the DM-F Local and DM-F PROFIsafe fail-safe expansion modules it is easy to integrate functions for fail-safe disconnection into the SIMOCODE pro V motor management system while retaining service-proven concepts. The strict separation of safety functions and operational functions proves particularly advantageous for planning, configuring and construction. Seamless integration in the motor management system leads to greater transparency for diagnostics and during operation of the system. Suitable components for this purpose are the DM-F Local and DM-F PROFIsafe fail-safe expansion modules, depending on the requirements: • the DM-F Local fail-safe digital module for when direct assignment between a fail-safe hardware shutdown signal and a motor feeder is required, or • the DM-F PROFIsafe fail-safe digital module for when a failsafe controller (F-CPU) creates the signal for the disconnection and transmits it in a fail-safe manner through PROFIBUS/PROFIsafe or PROFINET/PROFIsafe to the motor management system 3/67 Siemens IC 10 N · 12/2012 10/9 10 SIMOCODE pro is often used for automated processes where plant downtimes are very expensive (e.g. steel or cement industry) and where it is important to prevent plant downtimes through detailed operating, service and diagnostics data or to localize the fault very quickly in the event of a fault.
