As a temperature controller (TR) according to EN 14597 the devices are used in heat-generating plants to control the temperature of liquids or gases (mode of action: 1B).The high-contrast, multicolor LC display for process value, setpoint and operator prompting contains two four-digit 7-segment displays, two single-character 16-segment displays, display of the active setpoints, six switch position indicators, and displays for the dimensional unit,ramp function and manual operation.Simple operation through 4 keys. The instruments can be used as 2-state, 3-state, modulating or continuous controllers. The controller software includes a program or ramp function,parameter set changeover, two autotuning (self-optimization) procedures, a math and logic module, as well as 4 limit comparators.Linearizations for the usual transducers are stored, and a customer-specific linearization table can be programmed.A setup program is available for user-friendly configuration from a PC.A serial interface for RS422/485 or Profibus-DP can be used to integrate the instruments into a data network.The electrical connection is made at the back, via screw terminals.The possible input and output configurations are shown in the following block diagram. The option boards are universally applicable for all instruments in the series.JUMO dTRON 304Type 703044/...JUMO dTRON 308Q Type 703043/...JUMO dTRON 308H Type 703042/...JUMO dTRON 316Type 703041/...Key features+Up to two programmable analog inputs +Four programmable setpoints,two parameter sets+Program function with 8 segments, or ramp function +Math and logic module + 4 limit comparators +Two timers+Two self-optimization procedures +Fast, user-friendly configuration through the setup program with program editor +RS422/485 interface or PROFIBUS-DP interfaceApprovals/marks of conformity (see technical data)Self-optimizationStandard features include the tried and tested self-optimization, which makes it possible for the controller to be matched to the control loop by a user who is not a control technology expert.This functions by evaluating the response of the control loop to specific changes in the manipulating variable. Either an oscillatory method or a step-response test can be selected. The step-response test is used, for example, in the plastics industry or in processes where the oscillatory method cannot be employed. The controller parameters that are calculated are: proportional band, reset time, derivative time, cycle time and filter time constant.Customer-specific linearizationIn addition to the linearizations for the usual transducers, a customer-specific linearization can also be created. The programming is carried out in the setup program, in the form of a table of values or a formula.User dataParameters which are frequently changed by the user can be combined at the operating level under “User data” (only through the setup program).Math and logic moduleOrder details: Extra code 214The math module makes it possible to combine values such as the setpoints, output levels and measurements from the analog inputs into a mathematical formula.The logic module can be used, for instance, to make a logical combination of logic inputs and limit comparator states.Up to two math or logic formulae can be entered through the setup program, and the results of the calculations can be presented at the outputs or used for internal purposes. Special types of controller Order details: Extra codes 217, 218 and 219 The instrument can be operated as a differential, humidity or ratio controller.Logic functions–Start/cancel self-optimization–Change to manual mode–Hold/cancel ramp–Controller off–Setpoint changeover–Parameter set switching–Key/level inhibit–Text display–Display off–Acknowledge limit comparators–Program start/hold/cancel–Timer start/stopThe logic functions can be combined with one another (only through the setup program).Functions of the outputs–Analog input variables–Math–Process value–Setpoint–Ramp end value–Control deviation–Output level–Controller outputs–Limit comparators–Control contacts–Logic inputs–Logic formula–Program end–Timer signals–Program/automatic signalRamp functionEither a rising or a falling ramp function can beused (increase or decrease in the setpoint).The change in setpoint value SP at t0 is thefinal value for the ramp. The ramp starts withthe setpoint at time t0. The slope of the rampcan be programmed; the sign (direction) of theslope is given by the relationship between thesetpoint at time t0 and the SP value. When thesupply voltage is switched on, the rampfunction starts with the momentary processDisplays and controls(1)7-segment display (factory setting: process value)four-digit, red; decimal place is configurable (automatic adjustment on display overflow) (2)Active setpoint (factory setting: SP1)SP1, SP2, SP3, SP4 (SP=setpoint); green;(3)7-segment display (factory setting: setpoint)four-digit, green; decimal place is configurable,also used for operator prompting (display of parameter and level symbols)(4)Keys(5)Indicationyellow, for- switch status of logic outputs 1—6 (display lights up = ON)- ramp/program function is active- active manual operation(6)16-segment display for the unit °C/°F and texttwo-digit, green; with symbols for h, min, %additional display options through the setup programTimersTwo timers are available for time-dependentcontrol. The status of the timers can beswitched through to the logic outputs orinternally processed for the activation or de-activation of time-dependent processes.Setup program (accessory)The setup program for configuring theinstrument is available in English, French andGerman. Using a PC, you can create and editsets of data, and transfer them to thecontroller or read them out from theinstrument. The data sets are stored andmanaged.Program editorFor the easy creation of programs.Startup functionTo check the control-loop behavior.A setpoint profile can be implemented with a maximum of 8 program segments. The settings for the segment setpoints (SPP1—SPP8) and segment times (tP1—tP8) are carried out at the user level. The time scale can be configured as mm:ss or hh:mm (s = seconds, h = hours). A program-end signal can be generated, and the program can be halted or canceled.Further functions can be defined through the setup program (start at process value, cyclical program handling, segment-by-segment assignment of parameter sets and four control contacts). The program profile can also be visualized.Parameter levelAll the parameters and their meanings are included in the table. Some parameters may be missing or meaningless for a particular type of controller. Two parameter sets can be stored, to handle special applications.Parameter Value range Factory setting MeaningProportional band 0 to 9999 digits 0 digits Size of the proportional band0 means that the controller structure is out of action!Derivative time 0 to 9999 sec 80 sec Influences the differential component of the controller output signalReset time 0 to 9999 sec 350 sec Influences the integral component of the controller output signalCycle time0 to 999.9 sec20.0 secWhen using a switched output, the cycle time should be chosen so that the energy flow to the process is ascontinuous as is practicable without overloading the switching elements.Contact spacing 0 to 999.9 digits 0.0 digits The spacing between the two control contacts for 3-state or modulating controllersSwitching differential 0 to 999.9 digits 1.0 digits Hysteresis for switching controllers with proportional band = 0Actuator time 5 to 3000 sec 60 sec Actuator time range used by the control valve for modulating controllersWorking point -100 to +100%0%The output level for P and PD controllers (if x = w then y = Y0)Output level limiting0 to 100%100%The maximum limit for the output level -100 to +100 %-100%The minimum limit for the output levelInterfacesRS422/RS485 interfaceThe serial interface is used for communication with higher-level (supervisory) systems.The Modbus protocol is used for transmission.PROFIBUS-DPThe Profibus-DP interface can be used to integrate the controller into a fieldbus system operating according to the Profibus-DP standard. This Profibus version is especially designed for communication between automation systems and decentralized peripheral devices at the field level, and optimized for speed.Data transmission is made serially, using the RS485 standard.GSD generator, the project-planning tool that is supplied with the package (G SD =Gerätestammdaten, i.e. device data), is used to make a selection of device characteristics for the controller to create a standardized GSD file that is used to integrate the controller into the fieldbus system.Technical dataThermocouple inputInput for resistance thermometerInput for standard signalsLogic inputsMeasuring circuit monitoringIn the event of a fault, the outputs move to a defined (configurable) status.Designation Measuring range Measuring accuracyAmbienttemperature error Fe-Con L Fe-Con J Fe-Con U Cu-Con T NiCr-Ni K NiCr-Con E NiCrSi-NiSi N Pt10Rh-Pt S Pt13Rh-Pt R Pt30Rh-Pt6Rh B W5Re-W26Re C W3Re-W25Re D W3Re-W26Re EN 60584EN 60584EN 60584EN 60584EN 60584EN 60584EN 60584EN 60584-200to +900°C -200to +1200°C -200to +600°C -200to +400°C -200to +1372°C -200to +1000°C -100to +1300°C 0to 1768°C 0to 1768°C 0to 1820°C 0to 2320 °C 0to 2495 °C 0to 2400 °C≤0.25%≤0.25%≤0.25%≤0.25%≤0.25%≤0.25%≤0.25%≤0.25%≤0.25%≤0.25% in the range 300 to 1820°C ≤0.25%≤0.25%≤0.25%100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°C 100 ppm /°CCold junctionPt100, internalDesignationConnectionMeasuring rangeMeasuring accuracy Ambienttemperature error3-/4-wire2-wire Pt100EN 60751 (factory setting)2-wire / 3-wire / 4-wire -200to +850°C ≤0.05%≤0.4%50 ppm / °C Pt500EN 607512-wire / 3-wire / 4-wire -200 to +850°C ≤0.2%≤0.4%100 ppm /°C Pt1000EN 607512-wire / 3-wire / 4-wire -200 to +850°C ≤0.1%≤0.2%50 ppm /°C KTY11-62-wire -50 to +150°C≤2.0%50 ppm /°C Sensor lead resistance max. 30Ω per lead for 3-wire or 4-wire circuitMeasuring current approx. 250µALead compensationNot required for 3-wire or 4-wire circuit.

B1U3 Keys to ExercisesWarm-up1.1) stressed 2) identity 3) involved with 4) belong 5) coping with6) feel 7) bind 8) defined 9) supporting 10) beautyScript:The philosopher Plato once said, “Music gives a soul to the universe, wings to the mind, flight to the imagination and life to everything.” Music has always been a big part of my life. To create and to perform music connects you to people countries and lifetimes away. It connects you to the people you are playing with, to your audience, and to yourself. When I’m happy, when I’m sad, when I’m bored, when I’m stressed, I listen to and I create music.When I was younger, I played piano; later, I took up guitar. And as I started high school, music became a part of my identity. I was in every band, I was involved with every musical fine arts event. Music surrounded me. It made me who I was, and it gave me a place to belong.When I first arrived at university, I felt lost. It’s like I had been taken out of my natural environment, and put somewhere new, where the rhythms and the harmonies and the form had gone away. And there was just me, silence, and my melody. But then the next moment — I could hear it. And I could feel it. And it was me. And I was here. Music is my way of coping with the changes in my life.There’s a beautiful connection between music and life. It can bind us to reality, at the same time it allows us to escape it. So you see, everything is music. When I look at the world, I see music all around us. When I look at myself, I see music. And my life has been defined by music. I found myself through music. Music is everywhere, and it is in everything. And it changes and it builds and it diminishes. But it’s always there, supporting us, connecting us to each other, and showing us the beauty of the universe. So if you ever feel lost, stop and listen for your song. 2.

Just a waste of time.Q:What is the man’s attitude to the play?Keys1 C2 A3 A4 A5 B6 BNews reportScriptsA growing number of comics are finding their way into medical classes. Experts say that comics can be a great way of explaining complex or scary medical processes in an easy and entertaining manner. Medical teachers use comics a lot. Alex Thomas is one of them. He said, “We are trying to present scientific information with pictures so that medical students are excited to learn about it without realizing they are learning.” Besides, comics are a powerful medium for telling personal stories as the use of pictures can create a sense of emotion. In this way, medical students canunderstand the patients’ experience of illness emotionally.Keys1 C2 D3 CConversationScriptsTom: Mark, do you want to play basketball with me?Mark:I’d love to, but I have no time. I’ve got lots of homework to do.Tom: Oh, what a pity! Why are you so busy? You look stressed out.Mark: I always have so much to do.

What’s your college life like?Daughter: Mom, I guess college life is not as good as I expected. Actually, it’s a little bit disappointing.Mother: What makes you think so?Daughter: The food in the cafeteria doesn’t taste good. The teaching facilities are poor and there’re not many after-class activities to take part in. It’s not what I had in mind.Mother: Dear, I know how you feel. You just need some time to get used to your new college life. Daughter: Thank you for your understanding. I guess you’re right. Maybe it is not that bad. At leastI have got many new friends.Mother:I’m glad you’re thinking that way.Situation 2Lisa: Good morning, Mary. How was the movie you saw yesterday?Mary:Well, I don’t really like it.

That’s what friends are for.PassageScriptsHere is a true story regarding exams at Cambridge University. During an exam one day a bright student raised his hand and asked the teacher for cakes and beer, but was refused.“Sir, I really must insist. I request and require that you bring me cakes and beer”, the boy protested.Then the student took out a copy of the 400-year-old Laws of Cambridge still nominally in effect, and pointed to the part which said “Gentlemen sitting exams may request and require cakes and beer”.The surprised teacher had thus to meet his request and the student sat there, happily enjoying the treat while writing on the exam paper.Three weeks later, the student was fined five pounds for the reason that he was supposed to wear a sword to the exam according to the 400-year-old Laws of Cambridge.Keys11 F2 T3 T21 A2 C3 B31The truth is that without rules, life would be disordered; without rules, the world as we know it today would have been plunged into total anarchy. For instance, if we do whatever we want to do while driving, terrible accidents will become a common thing.Rules are the fabric upon which a society gets built. Also, the quality of life people enjoy is subject to the quality of rules.2Garbage classification refers to the separation of different categories in accordance with the environmental impact of garbage components and the requirements of existing treatment methods.Garbage classification is necessary and significant:·It reduces the mutual pollution between different garbage, which is beneficial to the recycling of materials.·It is conducive to the separation of ecological waste and non-ecological waste, reducing the difficulty of waste disposal.·It reduces the risk of secondary pollution of water, air, and soil.·It is conducive to reducing the final waste disposal volume.·It is conducive to developing social civilization.ReadingPassage ALanguage points1.Thanks to expanded licensing that brought more series to the international market, Chinese animation is getting more and more popular worldwide. (Para. 1)thanks to: used for saying that sb. or sth. is responsible for sth. good that happened 多亏；幸亏；归功于thanks to通常用于好的方面，多用于表达正面的意思，其引导的短语可以置于句首或句末。

Passing anti-trust laws.ScriptsToday we’re talking about the origins of modern business enterprises.The first examples of modern corporations began in the 1600s, with the British East India Company and the Dutch East India Company. What makes them modern is that for the first time the owners were not the managers. Decisions were made by appointed directors, but other people could own a “share”of the company. Being free of a single owner or manager, companies could grow bigger and last longer.The next major change began in the 1830s, with American railroad companies. They became the first truly modern management organizations, with middle managers employed to oversee workers. As the railroad companies grew, they absorbed smaller related companies and businesses. The smaller companies “trusted”the bigger company to manage them, which encouraged these bigger companies to grow into huge “trusts”.By the 1870s, these trusts controlled every aspect of the railroads, and had expanded into, and taken over, other sectors like banking and insurance. This created monopolies, not just in the railroads, but in almost every industry. They pushed out all their competitors, which led to high prices and corruption. Eventually anti-trust laws were passed in the 1920s, breaking up these trusts into smaller professionally managed corporations. This allowed competition, and with it innovation, to return.With the world of business changing so rapidly, enterprise is sure to adapt again, but for now this ends our lecture on the origins of the modern business enterprise.V IEWING2.Answers1) cherish2) implement3) promote4) intelligent5) best practices6) cultivate3. Answers1. more talents; competitive advantage2. constructive criticism3. assess4. positive change5. core functions6. implement7. systems thinkingScriptsThe Learning Organization: Characteristics of a Modern EnterpriseA learning organization encourages personal mastery and cultivates open feedback to see problems and opportunities on all levels. Some argue that learning organizations attract and retain more talents. Others say that there is a competitive advantage for an organization whose people learn faster than the people of other organizations. Here are 6 characteristics most have in common.They cherish an open culture. Learning organizations encourage everyone to share information, admit to mistakes and practice giving and taking constructive criticism. Once the problem is found, they try to understand its root cause and fix it. To achieve such a culture: walls are removed, information is shared and leaders show their human sides.They design and implement feedback loops. Some establish 360-degree surveys, in which people assess themselves, their peers and their bosses. Employees at 5-star hotels ask guests for their opinions. Top schools may videotape teachers so they can later study themselves. Some even make feedback a team effort. Before any new project, they all get together to kick things off. After the project they meet again to share and reflect on what has happened.They promote personal mastery. Employees try to achieve personal mastery in their fields. Once they become experts, they feel proud of their work, they are motivated intrinsically and they can create positive change wherever they are. For example, a cleaner might come up with an idea on how to save water and an accountant on how to save bank fees. The job of the boss is to connect all experts and give directions.They plan for intelligent fast failure. When they build something new, they don’t spend time to make assumptions on paper. Instead, they create what’s called Minimum Viable Product, a simple prototype with only the core functions. This is then presented to users as early as possible to test what they think. Because itis imperfect, even friends give their honest opinions. The goal: fail fast, but collect intelligent information so you can improve while going forward.They steal best practices. Picasso apparently said that good artists borrow, great artists steal. Learning organizations study others, steal best practices and then implement them fast. The newspaper The Economists took advice from George Orwell; its editors never use jargon if everyday English works. Printing manufacturers stole the razor-and-blades business model from Gillette, selling printers cheap but ink expensive.They cultivate a common vision. A learning organization prospers when all members share a common vision. That way employees can understand the importance of their role, connect the dots and develop systems thinking. When goals are clear, regulations can be reduced and people can create their own personal benchmarks of success. This reduces bureaucracy, authority and corruption. Salesman and author Zig Ziglar once wrote: “The only thing worse than training people and having them leave, is not training them and having them stay.”At a learning organization, education happens as a side-product of working together, as everybody learns from each other to adapt to whatever the future might bring.L ISTENING 2V OICE OF C HINA2. Answers33. Answers1) modern management2) clients3) water4) harmony5) multinational6) resources7) competitionScriptsIt is often said that Chinese wisdom, such as Confucianism, Daoism, and the works of thinkers like Sunzi, is a huge contributing factor to modern corporate success.The values of Confucian philosophy, such as trustworthiness, compassion, harmony and tolerance, are important in modern management. They are particularly useful in the context of interpersonal relations and human resource management, as well as general business networking and client relationships.In addition, Daoist philosophy advises leaders to be like water: able to adapt to different shapes and circumstances. It advises them to find balance and harmony between the many different perspectives, rather than simply impose orders. This has been shown to be particularly useful for managers working in multinational settings, where leaders need to understand and balance the cultural differences across countries.For leaders seeking a more strategic approach, there is Sunzi’s The Art of War. Sunzi’s book was originally a reflection on the art of military combat, but we can adapt his principles to businesses that face competition and have to know how to best apply their resources. For example, the great strategist said, “Know your enemy and know yourself, and you can fight a hundred battles with no danger of defeat”. Likewise, knowing your competitors, your market, and your own company’s strengths is vital for success.In this way, Confucianism, Daoism, and Sunzi’s The Art of War are important components of modern business studies and business strategy worldwide.F URTHER LISTENINGC ONVERSATION1.Answers1. C2. B3. C4. BScriptsInterviewer: Welcome, Mr. Timpson. Thank you for joining us today.

I always make time to relax. I have a family, so when it gets to 7 p.m., I sit back, switch off my laptop and phone, and spend time with my wife and kids. Sometimes I reada novel or listen to music.

What does the man say about his private life?P ASSAGE 12. Answers1. D2. C3. A4. AScriptsGood evening and welcome to this week’s culture report. A new run of the famous play, The Lehman Trilogy, was staged in London’s West End this week.The play is adapted from the three-act drama by Italian novelist Stefano Massini, and explores the change in fortunes over the 164-year history of the financial services firm, Lehman Brothers.Founded in 1850, the firm was the fourth largest investment bank in the United States with over 25,000 staff members worldwide. However, during the subprime mortgage crisis in 2007, it quickly lost clients and public confidence, which led to its bankruptcy in 2008.As the largest firm ever to file for bankruptcy in the U.S., it caused significant problems for the economy, which in turn led to the global financial crisis of the same year.Massini’s play amounts to a full 5-hour masterpiece of the theatre, exploring the fir m’s development, history and its collapse. British film director Sam Mendes, working with writer Ben Power, managed to reduce the original play into a 3-hour show for English-speaking audience. Due to its popularity, it is expected to enjoy future re-runs worldwide.Well, that’s all we’ve got time for. Enjoy your evening!Questions:Question 1. What is The Lehman Trilogy about?Question 2. What was notable about Lehman Brothers?Question 3. What is the speaker’s opinion of the play?Question 4. Which of the following is true about the Italian and English versions of the play?P ASSAGE 23. Answers1. A2. D3. AScriptsEnterprise resource allocation is the process by which companies decide which resources need to be invested in, maintained, replaced or removed as the company grows. These resources include labor and machinery, technology and materials, or even goods and services to provide.For example, the supermarket industry has invested in expensive new self-service technology, and the use of such technology has risen dramatically worldwide in the past decade. The enterprise resource allocationstrategy hopes that the high setup costs will be outweighed by the long-term benefits of reduced staffing costs and increased in-store efficiency.Australia is a good case study for this topic, being the country that led the way in adopting this new technology. As a result, in 2015 and 2016, staff numbers in Australian supermarkets were reduced, and were projected to remain flat for a number of years. However, since then, the number of staff has slightly risen again, due to the need of supervising the checkouts to prevent theft and the associated loss of revenue.Considering younger people’s familiarity with self-checkouts, plus the new developments in surveillance technology, greater automation is likely to be the future for supermarket retail. But it is worth noting that only larger firms have the space and can absorb those high setup costs, as well as possible losses due to theft.Questions:Question 1. What can we learn about self-service technology from the talk?Question 2. Why did the number of staff at supermarkets in Australia increase after 2016?Question 3. Which is a possible reason for smaller firms to avoid using self-checkouts?P ASSAGE 34.Answers1) Less decisive.2) (They dislike) changes.3) Law or accounting firms.4) The “Jellyfish” leader.5) Switch between leadership styles.ScriptsWelcome to Management for You. Today we’re talking about different leadership styles, all based on fish.First, there are “Dolphin” leaders. These people are enthusiastic, open-minded and friendly. They thrive on new tasks and take a positive approach to other people. This makes them ideal in PR, or as leaders in industries that require interpersonal interactions with new people and new problems. “Dolphin” leaders are great, but having too many of them in one organization might make operations less decisive. Sometimes you need a bit more firmness.This brings us to “Shark” leaders. “Shark” leaders like stability and dislike changes, but this isn’t always a bad thing. They can protect and defend the organization and its brand identity. “Shark” leaders are grounded, good at assessing risks, and can introduce changes in a structured way. This makes them ideal in law or accounting firms.But where neither the “Dolphin” nor the “Shark” leader is appropriate, you may find the “Jellyfish” leader. Jellyfish are relaxed, peaceful, and tend to go with the flow. This type of leader might be best suited to an industry where there is a lot of change in the external environment, like a charity.

Learn more about Hardware Mode on our web site or contact our Technical Support Department(**************).Identifying the KeysSelect appropriate icons or use the blank side of the legend sheet to create your own key legends. The keycaps snap off with a fingernail or small screwdriver. Apply the label under the keycap, and replace it. The key caps hold a legend 0.575" wide and 0.5" high (14.6mm x 12.7mm). Other options are available for printing legends for multiple units. Contact our Sales Department(***************)formoreinformation.Tall and Wide Double-keysThe included double-keys replace two single keys on the X-keys. To install a double key cap, remove two adjacent keys with the provided key-puller. Press the double-key in place over the two exposed switch stems and configure it in MW3.1 by selecting both keys, right-clicking, and selecting “Apply Large Key”. BacklightingAll keys on the XK-60 have two backlighting colors (red and blue) and advanced programming functions in MW3 allow the user to manipulate them. By default, when MW3 recognizes the X-keys, blue backlighting indicates the unit is ready for operation or programming. If you program a red layer shift or toggle key, the backlighting will also indicate the active layer.FeetThe included angled feet may be snapped in to the bottom of the XK-60 to give it a slight tilt in either portrait or landscape orientation.Compatible AccessoriesPlease visit the Accessories page on our website for details on the following.X-keys USB Extender – up to 150 feet via CAT 5 cableTall and wide keycapsColored and transparent key capsBlank key blockersOther Products from P.I.

It is reported that to build a road, a well-known historical and cultural city has recently torn down one of its ancient city walls (dating from the Tang Dynasty). Our class have had a debate on whether cultural relics like ancient walls should be torn down or not. About 10% of the students support this action, saying building a road is necessary for the development of society. In their opinion, cultural relics should give way to the development of society if necessary. However, about 90% have the opposite opinion . They believe such an ancient city wall is very valuable and it is one of the symbols of the city. There is no doubt that cultural relics play an important part in communication between China and the rest of the world. Personally, I think cultural relics are so valuable that we should protect them.
