2.1 The Present Continuous Tense

a Structure

The present continuous describes an action that takes place in the present and

is still going on in the present

+Subject + Verb + ing

Am / Is / Are e.g I/A dog e.g working/going/making

Examples:

Are they having the party on Friday or Saturday?

b Use

We most often use the Present Continuous when we talk about something which

is happening at the time of speaking (now, at the moment):

Examples:

Pamela is sleeping in the bedroom

The telephone is ringing!

Present Continuous is also used to express current trends:

Examples:

Fuel prices are rising constantly because of strong demand

On-line shopping is growing rapidly nowdays

Sometimes we use the Present Continuous to describe a planned action in thenear future:

Examples:

I'm leaving for Vienna tomorrow morning

We are having lunch at 12.30 o'clock

2.2 Exercises

Put the correct verbs

1 It ……….(to rain) right now

12 He ……….(to play)on his computer this afternoon

13 We ………(to eat) chicken wings at the moment: he is very hungry

14 What……….(you /do) ?I'm sleeping

2.3 Write the correct sentences

In most countries, electrical installations shall comply with more than one set ofregulations, issued by National Authorities or by recognized private bodies It isessential to take into account these local constraints before starting the design In so far

as control procedures are respected, quality and safety will be assured only if:

The initial checking of conformity of the electrical installation with the standardand regulation has been achieved

The electrical equipment comply with standards

The periodic checking of the installation recommended by the equipmentmanufacturer is respected

3.2 Equipment used to install

Multi-Satellite Dish Reflector Dish Mounting Hardware LNB Arm/Antenna Back

Assembly

Triple-head, Multi-Satellite

LNB with built-in Multi-Switch

for four Independent Outputs

LNB Mounting Hardware

Fig 1.3: Cable Since most Direct TV (DTV) DVRs and TiVOs have dual tuners, consider running two cables instead of just one In the case of the DTV High Definition DVR

or DTV High Definition TiVO, consider three cables if you wish to connect an “offair” antenna to receive local channels that are not available from DTV If DVRs arenot planned, installing one cable will supply a simple DTV receiver

Fig 1.4: No trees, leaves, buildings can be in the line-of-sight between antenna and

# 22 to # 32

Sat C, 110° with Converted Transponders

# 8, #10, #12

Install a ground block in a convenient location anywhere between the dish and prior to entering the home It is permissible to locate the ground block inside the home, but it should be as close to the point of entry as possible If unable to purchase a

ground block to accept all inputs and outputs, it will be required to add additionalground blocks as needed to accommodate all the connections

Install a #10 copper wire between the house ground point (ground rod, electric meter, etc.) and the grounding terminal screw of the new ground block These two points must be connected together Use a clamp designed for the purpose to connect the #10 wire

to the house’s ground point Do not under any circumstances disconnect or loosen existingground connections to install the new #10 wire Leave enough ground wire to “thread”through each ground block(s) ground terminal Route the cable and secure with staples tothe mounting surface Securely tighten the ground terminal screw to the ground wire

Run coax cables from each of the dish's output terminals into one side of the ground block.

Run a cable from any rooftop UHF/VHF/FM antenna (if desired) to the same side of the ground block as the dish coax.

Run the same number of cables that were run into the ground block, between the ground block and a central location A utility closet, a point near the telephone

distribution block or electrical panel area is ideal Label the coax cables “dish” or othermeaningful manner Be sure to label the coax from a roof top antenna if extended fromthe ground block

Run cables from each tuner to the central location Affix labels to each of the

cables - if two cables are connected to a single set top box, such as the case for a TiVO

or DVR in a living room, label the cables “LR1” and the other “LR2” or some othermeaningful term

Select a multiswitch by determining how many inputs and outputs are needed The number of inputs equals the number of LNBs on the dish plus one A dual LNB

dish would require a three input multiswitch The extra input is to mix in an “off air”antenna or CATV signal The number of outputs of the multiswitch equals the number

of tuners (not the number of receivers or set top boxes) in your system A system of

three set top boxes consisting of two DTV receivers and a DTV DVR or TiVO withtwo tuners would require a four output multiswitch Of course, if you add anotherreceiver later, you'll need a multiswitch that has additional outputs Try to buy amultiswitch with enough extra outputs to allow your system to “grow” Cascadablemultiswitches can be installed “down line” from other multiswitches, but must beidentified for that use

A “3X4” Multiswitch It has two LNB (dish) inputs, a single ANT (antenna orcable) input and four RXn (receiver) outputs Three inputs and four outputs - hence3X4

Fig 1.6:

Multiswitches become more expensive as the number of inputs and outputs increase DTV will install as many as needed free of charge when they add or change

equipment such as receivers or antennas It’s best to let DTV do this, but there is noreason why you can't if the cost is not an issue.

Mount the multiswitch(es) and connect the dish coax cables to the dish input connector, and the antenna or Cable TV coax to the antenna input connector Connect

the coax cables from the receivers to the the multiswitch output connectors Snug theconnectors to “finger tight” for now

At the receiver end, connect coax cables(s) to each tuner input(s) The satellite

cables connect to the satellite inputs - it does not matter which one If you ran only onesatellite cable, connect it to satellite input 1 If this is a location that will need an off airantenna input as well, instead of connecting a cable directly into the tuner, connect it

to a “diplexer” input instead The diplexer will have a diagram indicating satellite andUHF/VHF connections The diplexer “satellite out” connects to the DTV receivertuner, and the UHF/VHF can connect to the “antenna” or “CATV” input of the DTVset top box OR even an FM Stereo receiver

Fig 1.7:

Check picture quality at each location Change channels to test both tuners for

TiVOs and DVRs Alternatively, use the receiver's set up pages to view signalstrengths of each satellite and tuner Check connections and hardware until satisfied

Securely tighten the coax connectors along each cable whereever they appear with a wrench, starting at the TV, receiver, multiswitch and ending at the ground block

or dish Do not over-tighten.

5 Test the voltage of the cable

Disconnect the coaxial cable from the TV or cable box and position it for easyaccess

Set the voltmeter to read AC (alternating current) voltage

Touch one probe of the voltmeter to the center wire At the same time, touchthe other probe to the shielding, which will be the outside area that screws into thecoaxial stud

Read the display on the multimeter to determine the voltage

2 Grammar

2.1 Language study: Making safety rules

We can make safety rules in these ways:

1 Using an imperative

a Wear protective clothing

b Do not wear loose – fitting clothing

2 Always / never are used to emphasize that the rule holds in all cases

a Always wear protective clothing

b Never wear loose – fitting clothing

3 We can use a modal verb for emphasis

a Protective clothing must be worn

b Protective clothing should be worn

4 Study this list of unsafe environmental conditions (hazards) Write safety rules to

limit these hazards using the methods given above For example:

e badly maintained machinery

f carelessly stored dangerous materials

g inadequate ventilation

h damaged tools and equipment

i machinery in poor condition

j equipment used improperly

k equipment operated by untrained personnel

l apprentices working without supervision

2.2 Writing: Ways of linking ideas

Because, because of, in addition, moreover, for example, for instance

Linking words are used to link ideas when writing They enable the writing toflow from one idea to the next in a logical and cohesive way

- Because and because of are both used to introduce reasons Because is followed by a subject and a verb Because of is followed by a noun or noun phrase.

The accident happened because the operator was carelessness.

The accident happened because of the operator’s carelessness.

- In addition and moreover are used to add information to what has already

been said

The accident happened because of the operator’s carelessness In addition/Moreover, the supervisor was not present.

- For example and for instance can be used completely interchangeably to

introduce an example to illustrate what is being discussed

Suitable protection should be worn For example/For instance, safety helmets

should be used where there is a danger of falling objects.

Combine these sentences using appropriate linking words from this unit

a Many accidents happen

Workers’ carelessness

b Safety gloves provide protection for the hands

They prevent burns

They reduce the danger of cuts

c Safety shoes protect the feet against falling objects

They prevent the feet getting caught in machinery

d Respirators should be worn in dusty conditions

Fig 3.16:

Three VFD modules will be installed at Pump Stations 1, 3, 4, and 9 All threewill contain VFDs, while two will also contain switchgear A platform adjacent to themodule will hold a cooling system for the liquid-cooled VFD, a transformer to stepdown the incoming power from 13,800 volts to 6,600 volts, and a station transformer

to provide 480-volt power to the module The VFD controls the frequency of thepower in order to vary the speed of the pump motors The photo below shows a 3-Drendering of the three VFD modules planned for Pump Station 4

Fig 3.17:

The photo above shows part of the ABB

switchgear with the front panels open The

switchgear consists of a series of sections The

frst on the left houses the control wiring for the

switchgear The section at right contains the

circuit breaker and the computer (multifunction

protective relay) that controls that breaker Each

VFD module will have six or seven breakers

The computer can sense the full range of current

and can be programmed from a laptop

computer In addition, a communications

module will interface with the PLC Fig 3.18: Switchgear

3.3 Install and check control panel on Home Security System

1 Survey your home and determine how many windows and doors you want to

be “switched”, or integrated into the home security system

2 Determine possible locations for the

control panel and keypads You might find it

convenient to place a keypad close to the

front door You might also want a keypad

close to the bedrooms The control panel

commands the system, and the keypads

allow you to program the system and turn it,

or its components, on and off

Fig 3.24:

3 Determine how far away windows and doors are

from the control panel so that you know how far

wires will be routed if you choose a wired alarm

system or how far a wireless system needs to

communicate with sensors Keep in mind that it is

difficult to install a hard-wired security system

unless your house is still under construction

Fig 3.25:

4 Decide whether you want a monitored security

system that will be monitored 24 hours a day The

central monitoring station ‘watches’ your home for

a monthly fee A less expensive alternative is a

basic sensor system with a dialer accessory that

connects the system to your phone lines and dials

preselected numbers if the house’s security is

breached

Fig 3.26:

5 Consider your lifestyle Does anyone in the family often get up in the middle of thenight for a snack? Do you have a large pet that roams the house at night? Suchcircumstances will influence the type of motion sensor you select and how it isinstalled It may also call for you or members of your family to take trips to the keypad

to prevent false alarms

A The present participle may often function as an adjective:

That's an interesting book

That tree is a weeping willow

B The present participle can be used as a noun denoting an activity (this form is also called a gerund):

Swimming is good exercise

Traveling is fun

C The present participle can indicate an action that is taking place, although it cannot stand by itself as a verb In these cases it generally modifies a noun (or pronoun), an

adverb, or a past participle:

Thinking myself lost, I gave up all hope

Washing clothes is not my idea of a job

Looking ahead is important

D The present participle may be used with “while” or “by” to express an idea of simultaneity (“while”) or causality (“by”):

He finished dinner while watching television

By using a dictionary he could find all the words

While speaking on the phone, she doodled

By calling the police you saved my life!

E The present participle of the auxiliary “have” may be used with the past participle

to describe a past condition resulting in another action:

Having spent all his money, he returned home

Having told herself that she would be too late, she accelerated

2.2 Exercise

Rewrite the sentences replacing the italic part with a present participle.

1 She was talking to her friend and forgot everything around her.

7 As they didn't have enough money they spent their holidays at home last year.
