■ Overview


Automatic transfer control via the 3KC ATC5300

The 3KC ATC5300 transfer control device, equipped with two motor-driven circuit breakers, serves as a transfer system that automatically or manually switches between two power supply systems in low-voltage power distribution applications.

In particular, the 3KC ATC5300 transfer control device is deployed everywhere where a power failure is especially critical, e. g. in hospitals, in conjunction with UPS systems, and for industrial processes.

Mode of operation

The 3KC ATC5300 transfer control device controls the transfer between the main and standby power supplies fully automati-cally, while incorporating set limit values and delay times. It de-tects fluctuations occurring in the main power supply quickly and switches to the standby power supply. The control device only switches to the standby power supply after it has ensured that the standby supply is delivering the required power supply quality. The device switches back to the main power supply, taking into consideration the set parameters, once the required power supply quality is available again. If the standby power supply and/or the main power supply is fed by a generator, the control device also offers a wide range of settings, such as a generator lead time, generator delay time, and generator start test at specified times.

The 3KC ATC5300 transfer control device can control air circuit breakers, compact molded case circuit breakers, switch discon-nectors and contactors. The circuit breakers are controlled via the related motorized operating mechanisms.

Setting parameters and monitoring using SENTRON ATC software

In addition to operation and parameterization on-site, you can also monitor and set the parameters of the controller using the SENTRON ATC software. The software offers a high level of con-venience and quick access to all device settings, e.g. complex settings which occur when connecting generators.

12/9Siemens LV 10.1 · 2012

■ Overview

Plant safety and operating safety are becoming increasingly im-portant alongside the protection of personnel. Shutdowns due to the unexpected tripping of protective devices cause high costs. It is possible to detect residual currents in the electrical installa-tion before the protective device responds.

Residual current monitors (RCM) monitor residual current in electrical installations and issue a signal when the residual cur-rent exceeds a set value.

RCMs are used primarily in plants where a fault should result in a signal but not in disconnection. This enables plant operators to detect faults and eliminate their causes before the protective de-vices disconnect the installation, which increases plant and op-erating safety and cuts costs.

The summation current transformer detects all conductors re-quired to conduct the current, i. e. including the neutral conduc-tor where applicable. In a fault-free system, the magnetizing ef-fects of the conductors through which current is flowing cancel each other out for the summation current transformer, i. e. the sum of all currents is zero. If a residual current is flowing due to an insulation fault, a residual magnetic field is left in the core of the transformer and produces a voltage. This voltage is evalu-ated using the electronics of the RCM. The switched contact can be used e. g. to operate an acoustic/optical signaling device, a higher-level control system or a circuit breaker.

Time characteristic of the rated residual current ΙDn

■ Benefits

• Higher plant availability and operating safety through perma-nent monitoring of residual currents

• Adjustable limit values for residual current and response time enable timely detection and signaling – plant shutdowns are often avoidable

• Devices for every application: The summation current transformers are available in various sizes, the RCMs can be used optionally for signaling and/or switching

• Additional fire protection can be implemented using the monitoring system.

5TT6 priority switches


■ Overview

In the mixed operation of electric hot water and electric storage heaters, the priority switch interrupts the charging procedure of the storage heater if hot water is required during the low-tariff time, thus limiting the connected load in compliance with BTO § 6. The control circuit terminals must be sealable.

■ Benefits

Reduction of the connection fee, which depends on the maxi-mum load to be supplied (BTO, German Federal Regulation on Tariffs § 6 Section 4), when used in systems with continuous-flow heaters and electric storage heaters where the continuous-flow heaters are switched with priority.

■ Overview

Fuse monitors serve to monitor all types and versions of melting fuses that cannot be equipped with a fault signal contact. This enables integration in fault signaling circuits or a central alarm in order to improve plant availability.

■ Benefits

• Increase in plant availability, because fuse failures – which could cause considerable damage to the plant – are detected in plenty of time.

• A fuse failure is detected even if the load is switched off. This ensures the highest level of plant availability.

■ Overview

In areas that conform to Group 2 of DIN VDE 0100-710, any in-terruption to the examination and/or treatment of patients would place those patients at risk.

Limit monitoring

This is prevented through the use of changeover and monitoring units. These monitor the insulation resistance of the non-grounded IT system, the load current and the temperature of the transformer. If the limit value is exceeded, the insulation monitor gives out a warning signal.

Voltage monitoring

In addition, a special voltage relay monitors the voltage of the power supply and switches to a second power supply if it falls below the specified limit values.

■ Benefits

• TÜV-certified switchover device with increased functionality• Plant state signal over contacts – No specific manufacturer's

bus system• Easy operation over potentiometers as the set limit value is al-

ways visible • Easy to integrate in existing plants, including plants from other

manufacturers.

5TT3 fault signaling units


12

■ Overview

Fault signaling units are used in small plants where the installa-tion of complex fault signaling systems would be too labor-inten-sive and too expensive. In the event of a fault, they enable fast fault localization of all monitoring devices and limit monitors from a central location. This increases plant availability. With the cor-rect sensor configuration, they also provide the option of preven-tative maintenance.• 4 fault signal inputs with LED• 1 LED as centralized fault indicator• One unit each for centralized fault indication and acoustic

signaling• With acknowledgment for acoustic indicators• Open-/closed-circuit principle to the 4 inputs can be adjusted

via jumpers X1 - X2• A maximum of 39 5TT3 461 expansion fault signaling units can

be connected to the 5TT3 460 centralized fault signaling unit• The maximum possible cable length between 5TT3 460 cen-

tralized fault signaling units and 5TT3 461 expansion fault sig-naling units is approx. 100 m with a conductor cross-section of 1.5 mm2.

■ Benefits

• Ultra compact device designs that only require the smallest of spaces in distribution boards

• The modular design means that it is easy to add devices as your system expands.

5TT5 EMERGENCY STOP modules


■ Overview

EMERGENCY STOP circuits are common safety measures in all laboratory equipment and industrial plants. The EMERGENCY STOP modules used here must meet the most rigorous demands with regard to functional reliability. Benchmark is the degree of self-monitoring. The Directive 98/37/EC on Safety of Machines, valid from 2-31-1994, only specifies global safety standards. De-tails on how to implement individual safety demands are defined in standards, e. g. by the European Committee for Electrotechni-cal Standardization (CENELEC), which are based on interna-tional standards.

■ Benefits

• The electrical isolation between electric circuit and control meets the requirements of the standard

• An LED for the operating and switching state provides con-stant information on the operating state

• The safety category 4 to EN 954-1 expands the application options in many fields

• Compliance with the regulations according to EC Machine Directive 98/37/EC supports a high safety standard for those working in the plants.

5TT3 level relays

12/30 Siemens LV 10.1 · 2012

12

■ Overview

Level relays are used for the monitoring and control of conduc-tive, non-combustible liquids and powders. They ensure over-flow and dry run protection. Due to their sensor performance, the devices can also be used for general resistance monitoring.

LED displays:• Green LED: lights up when operational voltage is applied• Yellow LED: lights up if MIN output relay is activated• Red LED: lights up if MAX output relay is activated.

■ Benefits

The measuring range up to 450 kΩ enables a differentiation be-tween foam and liquid. It also increases the universal application for resistance measurements.

Due to its low-frequency, electrically isolated measuring circuit, the device has a high immunity to interference against system coupling, which enables cable lengths of up to 1500 m and sup-presses the effects of electrolysis in the liquid• The two outputs for minimum and maximum control can also

be used for the advance warning and tripping of limit values• 3 electrode connections for 1-step and 2-step level control• All standard products can be used as electrodes• High immunity to interference of the measuring circuit isolated

from the system• Programmable for open-circuit principle (with bridge X2 COM)

or closed-circuit principle (without jumper)• Separately adjustable delay times for tv min and tv max,

5TT3 line circuit relays


12

■ Overview

Line circuit relays are used to interrupt circuits and prevent elec-tromagnetic fields in circuits where there are currently no active loads. If the loads are disconnected, and the line circuit relay measures a usage of only 2 to 20 VA - adjustable - it disconnects the cable to the supply voltage and switches over to extra-low voltage. As soon as loads are reconnected, the line circuit relay detects the increase in usage and switches back to the supply voltage. While the line circuit relay switches off any unnecessary system components, it is not a device for ensuring isolation in the sense of safe disconnection.

The line circuit relay is unable to detect consumers with elec-tronic power supply units, e. g. electronically controlled vacuum cleaners. It is expedient to connect such devices to a base load resistor (PTC resistor) so that the line circuit relay is reset to sup-ply voltage.

■ Benefits

• High availability to a wide range of loads, as all resistive, capacitive and inductive loads are detected

• Adjustable from 2 VA to 20 VA• With status display for contact adjustment• With switch continuously ON• With safety information on stickers for socket outlets and

distribution boards.

7LQ2 dusk switches

12/33Siemens LV 10.1 · 2012

12

■ Overview

Dusk switches are used for the demand-oriented switching of lighting installations for shop windows or paths in order to cut operating costs. A light sensor measures the level of daylight. Switching depends on the desired brightness. A time delay and the switching hys-teresis prevent clock-pulse behavior. The sensor must be mounted so that it is not influenced by the lighting feedback.

■ Benefits

• The devices 7LQ2 101 and 7LQ2 103 have 2 switching chan-nels that can be set independently of each other. This requires a light sensor

• 12 dusk switches can be switched parallel to a light sensor. This saves the multiple installation of light sensors in a single system and all dusk switches operate independently of each other and can be adjusted individually.

5TT3 p.f. monitors


■ Overview

The p.f. controllers monitor the phase displacement between current and voltage. Because the phase displacement angle changes with the load of the motor, this measurement method is ideal for the monitoring of asynchronous motors for underload and no-load operation, independent of size. However, in some cases, the p.f. barely changes if the load of the motor changes, e. g. in the case of relatively minor load changes on large-scale motors or single-phase split-pole motors or collector motors.

The p.f. controller monitors single and three-phase asynchro-nous motors up to approx. 5 A (without current transformer) for underload and no-load operation. This is phase-sequence-inde-pendent and increases plant availability. Typical applications are fan monitoring in the case of V-belt breakage, pump monitoring

in the event of valve closure or dry runs. A current transformer is used for higher rated currents.

If the p.f. value set at the p.f. monitor is fallen below for the dura-tion of the set response delay, the output relay switches to the alarm state and the red LED lights up. If it exceeds the p.f. value, the output relay switches back without any significant delay.• Adjustable p.f. response value, from 0 to 0.97• Current range up to 8 A• LED display for operation and alarm• Automatic resetting of alarm.

■ Benefits

• The ultra compact p.f. controller requires only the smallest of spaces and saves costs.

5TT3 motor protection relays


12

■ Overview

Thermistor motor protection relays monitor the thermistors wound in motors. This helps prevent thermal motor overloads, e. g. due to high switching frequency, single-phasing, disabled cooling or excessive ambient temperatures. Up to 6 thermistors in series can be monitored. A conductor break in the sensor con-ductor will immediately trip the device. The device can also be used for monitoring wound quick-break switches - e. g. bimetal thermostats. This offers all-round motor protection.• For the detection of

- Temperature limits being exceeded- Wire breaks in sensor circuits

• 1 input for 1 to 6 thermistors• With 2 LEDs green/red for ready-to-run and fault

• Response value: 3.2 to 3.8 kΩ• Release value: 1.5 to 1.8 kΩ• Max. cable length of sensor supply cable NYM 2 × 1.5

is 100 m• Remote Reset: over A1/A2 (NC contact) or over X1/X2

(NO contact)

LED displays:• Green LED: lights up when operational voltage is applied• Red LED: lights up in the event of overtemperatures or an in-

terruption in the sensor circuit.

■ Benefits

• The test button for the diagnosis of the devices ensures high functional reliability for users

• The ultra compact thermistor motor protection relay requires only the smallest of spaces. This saves costs

• A remote reset enables the device to be switched back on again centrally at any time. This increases plant availability.

CM-100 charging controller acc. to IEC 61851

12/39Siemens LV 10.1 · 2012

■ Overview

IEC 61851 describes the safety requirements which must be met by conductive charging systems for electric vehicles. Standard-compliant AC charging in operating mode 3 requires the SIPLUS ECC1000 CM-100 charging controller, which is perma-nently installed in a charging station in order to communicate with the electric vehicle via the charging cable. It identifies whether the correct charging cable is connected. If yes, the plug interlock will be activated and a feedback signal sent to the charging controller. A further enable signal, e. g. via a key-oper-ated switch, actuates the 5TT5 Insta contactor for the charging current circuit and the charging operation can start.
