m WIRING DIAGRAMSwSOME COMMON and IMPORTANT TERMS

In this booklet, and wherever motor control is discussed, there are several terms which are used repeatedly but whosemeanings are often not completely understood by the reader. These terms represent things which are actually quitesimple and everyone should become familiar with them as standard motor control jargon.UNDERVOLTAGE RELEASE

Also Called: Low-Voltage ReleaseTwo-Wire ControlThese terms mean that the starter will drop out whenthere is a voltage failure and will pick up again as soonas voltage returns. Reference to the diagram below willshow how this occurs. The pilot device is unaffected bythe loss of voltage and its contact remains closed, readyto carry current as soon as line voltage returns tonormal.

Two wres lead from the plot devrce to the starter. Undervol tage releaseandtwo-wwe control should brrng to mrnd an automatrc p/lot devrc e such as alrmrt swrtch or float switch whose functron IS openmg and closrng the controlcrrcurt by means of a smgle contact.

UNDERVOLTAGE PROTECTIONAlso Called: Low-Voltage ProtectionThree-Wire Control

These terms mean that the starter will drop out whenthere is a voltage failure but will not pick up automat-ically when voltage returns. The control circuit iscompleted through the STOP button and also througha holding contact (2-3) on the starter. When thestarter drops out, this contact opens, breaking thecontrol circuit until the START button is pressed onceagain.

%

t3Three Wires

Three wjfes lead from the p/lot devtce to thestarter. Undervoltage protectionand three-wrre control should brmg to mrnd a START-STOP push buttonstat/on whrch IS the most common means of provrdrng this type of control.

The main distinction between the above two types of control is that with undervoltage release the coil circuit ismaintained through the pilot switch contact, and with undervoltage protection it is maintained through a stopcontact on the push button station and also an auxiliary contact on the starter. The designations two-wire andthree-wire are used only because they describe the simplest applications of the two types. Actually, in othersystems, there might be more wires leading from pilot device to starter but the principle of two-wire or three-wirecontrol would still be present.

WIRING DIAGRAMS vs LINE DIAGRAMSMost of the diagrams in this book are shown in twoways. There is a wiring diagram and adjacent to it aline diagram. Line diagrams are included becausetheir use is becoming more widespread and we believeit is advantageous to learn to use them.

Wiring diagrams or connection diagrams include allof the devices in the system and show their physicalrelation to each other. All poles, terminals, coils, etc.are shown in their proper place on each device. Thesediagrams are helpful in wiring-up systems, becauseconnections can be made exactly as they are shown onthe diagram. In following the electrical sequence of anycircuit, however, the wiring diagram does not show theconnections in a manner that can be easily followed.For this reason a rearrangement of the circuit elementsto form a line diagram is desirable.

The line diagram (sometimes referred to as anelementary diagram or a schematic diagram) is arepresentation of the system showing it in the simplest

way. No attempt is made to show the various devices intheir actual relative positions. All control devices areshown between vertical lines which represent thesource of control power, and circuits are shownconnected as directly as possible from one of theselines to the other. All connections are made in such away that the functioning of the various devices can beeasily traced. Note: In this publication the line diagramsshow the control circuits only - power circuits areomitted for clarity, since they can be traced readily onthe wiring diagrams (heavy lines).

A wiring diagram gives the necessary information foractually wiring-up a group of control devices or forphysically tracing wires when trouble-shooting isnecessary. A line diagram gives the necessary informa-tion for easily following the operation of the variousdevices in the circuit. It is a great aid in trouble-shooting as it shows, in a simple way, the effect thatopening or closing various contacts has on otherdevices in the circuit.

Comparison of the picture and drawing shown above should help the reader becomefamiliar with the Allen-Bradley Bulletin 509 starter as it is represented in wiring diagramform. Principal corresponding parts are labeled so that the wiring diagram can be comparedwith the actual starter. This should aid in visualizing the starter when studying a wiringdiagram and will help in making connections when it is actually wired up. Note that thewiring diagram shows as many parts as possible in their proper relative positions. It is notnecessary to show the armature and crossbar or the overload reset mechanism in the wiringdiagram since these parts need not be considered from the wiring standpoint.The Size 1 starter is shown here because all of the special wiring diagrams in this booklet useSize 1 starters as examples. The other sizes of starters have a similar appearance as the Size1 and their principle of operation is the same. Wiring of the other sizes of starters is the sameas for Size I although some of the connections are not physically located in the same placesas on the Size 1.

A maintained overload on any motor, trippingout the overload relays on its respective starter, will drop out all three starters disconnectingall motors from the line.Assuming that standard Bulletin 509, Form 2 starters are to be used, then in order to obtainthe desired operation, the wiring connection Y must be removed from each starter. Thecontrol circuits of the several starters are interconnected. It is therefore necessary todisconnect the power to the line terminals of all the starters in order to completelydisconnect the equipment from line voltage.

However, a maintained overload, tripping a relayon any one of the starters, will automatically drop out all of the starters. A master STOPstation wired into the circuit as illustrated will trip out all starters when pushed.To obtain the desired operation using standard Bulletin 509 Form 2starters, wireX must beremoved from all but one of the starters.

System Provides Backspin Protection andSurge Protection on Stopping.- Time DelayBetween Pressure Switch Closing and MotorStartingThe pressure switch energizes the timer (TR),but the motor cannot start until the time delaycontact has closed. The timer can thus be setfor a time long enough to allow all surges andbackspin to stop.The dotted lines show how a selector switchcan be added to by-pass the pressure switch ifnecessary. This is often used for motor testingpurposes. It does not eliminate the time delayhowever. If the selector switch is added, thewire A must be removed.

Backspin ProtectionAutomatically IncludedTwo timing relays are used here, one toprovide surge protection on starting and oneto provide surge protection on stopping andbackspin protection. TRl is an on-delaytimer used for surge protection on starting.When the pressure switch contact closes,relay CR, the starter and the two timers areenergized. The instantaneous contact on TRlcloses, by-passing the pressure switch con-tact and preventing the pump motor starterfrom dropping out even though starting surgesopen the pressure contact. After the timingperiod, the time delay contact TRl opens theby-pass and PS can then stop the pump at theproper pressure. TR2 is an off-delay timerfor surge protection on stopping and back-spin protection. Once turned off, the systemcannot be operated again until timer TR2 hastimed out and its normally closed contact isclosed.When a standard Bulletin 509 starter withoutpush buttons is used, connection Y must beremoved. 34

Sequence Control of Two Motors- Oneto Start and Run for a Short Time After theOther Stops

In this system it is desired to have asecond motor started automatically whenthe first is stopped. The second motor isto run only for a given length of time.Such an application might be foundwhere the second motor is needed to runa cooling fan or a pump.To accomplish this an off-delay timer(TR) is used. When the start button ispressed, it energizes both Ml and TR.The operation of TR closes its time delaycontact but the circuit to M2 is kept openby the opening of the instantaneouscontact. As soon as the stop button ispressed, both Ml and TR are droppedout. This closes the instantaneous con-tact on TR and starts M2. M2 will continueto run until TR times out and the timedelay contact opens.

35

Starters Arranged for Sequence Controlof a Conveyor SystemThe two starters are wired so that M2cannot be started until Ml is running.This is necessary if Ml is driving aconveyor fed by another conveyor drivenby M2. Material from the M2 conveyorwould pile up if the Ml conveyor couldnot move and carry it away.If a series of conveyors is involved, thecontrol circuits of the additional starterscan be interlocked in the same way. Thatis, M3 would be connected to M2 in thesame step arrangement that M2 is nowconnected to Ml, and so on.The Ml stop button or an overload on Mlwill stop both conveyors. The M2 stopbutton or an overload on M2 will stop onlyM2.If standard Bul. 509 starters are used, wireX must be removed from M2.

Operation of Any One of Several Starters Causes a Pump or Fan Motor to StartSeveral motors are to be run independent of each other, with some of the starters actuated by two-wire andsome by three-wire pilot devices. Whenever any one of these motors is running, a pump or fan motor must alsorun.A master start and stop push button station with a control relay is used to shut down the entire system in anemergency. Control relay (CR) provides three-wire control for Ml which is controlled by a two wire controldevice such as a pressure switch. Motors M2 and M3 are controlled by START-STOP push button stations.Auxiliary contacts on Ml, M2, and M3 control M4. These auxiliary contacts are all wired in parallel so that anyone of them may start M4. Bulletin 595 auxiliary contacts have been added to M2 and M3 for this purpose. Thestandard hold-in contact on Ml may be used as an auxiliary if wire Y is removed. Hold-in contacts are notrequired when a two-wire control device is used.The Bulletin 595 auxiliary contacts are designed as A and B on the wiring diagram. These contacts are easilyadded to any Allen-Bradley Bulletin 500 starter sizes 0 through 4.When this system is used, the phase connections on all of the starters must be the same. That is, Ll of eachstarter must be connected to the same incoming phase line, L2 and L3 of each starter must besimilarly phasedout.

Push Button Wired so Starter Can Be Switched from One Direction to the OtherWithout Pushing STOP ButtonThis scheme allows immediate reversal of the motor when i t is running in either direction. It is notnecessary to depress the STOP button when changing direction. A standard Bulletin 505 reversingswitch can be used if wire W is removed.The diagram shows the control circuit set up for reduced voltage control, although this may not benecessary in many cases. Notice that wire X must be removed when reduced voltage control is used. Thepush button station can be a Catalog Number 800S-3SA (standard duty), 800H-3HA (heavy duty) or aCatalog Number 800T-3TA (oiltight).

Once again, standard Bulle-tin 505 reversing switch can beused if wire W is removed. Thepilot lights can either be separate-ly mounted or mounted in thepush button station. If they are tobe mounted in the station a Cata-log Number 800H-3HA2P can beused.

3 Phase Lines The Motor Runs in a PreselectedDirection Which is Determined byThe Setting of a Selector SwitchThe motor can be run in eitherdirection, but the desired direc-tion must be set on a selectorswitch before starting. The motoris then operated from a START-STOP station as a single direc-tion motor.The wiring of the standard Bulle-tin 505 reversing starter must bemodified slightly to fill this re-quirement. Note that the connec-tions which normally lead fromthe electrical interlock contactsto points 3 and 5 have beenremoved and that different con-nections have been made to theelectrical interlocks and points 3and 5.It is usually most convenient toinclude theselector switch as partof the push button station. Thiscan be done with either a Bulletin800H heavy duty station or aBulletin 800T oiltight station.

Limit Switch ControlsReversing

Here the direction of the motoris determined by the positionof a limit switch. A START-STOP push button station isused to energize the systemand the motor will start ac-cording to the position of thelimit switch. The wiring of thestandard Bulletin 505 need notbe modified for this type ofoperation. Limit switch con-nections are made directly tothe electrical interlocks.It is necessary to use a controlrelay in this system such as aCatalog Number 700-C200. Thelimit switch can be any ofseveral in the Bulletin 802Tline having one NO and oneNC contact.

Jogging With RelaysIn this arrangement for jog-ging and running in eitherdirection jogging relays areused to provide proper jog-ging. These relays guardagainst either the forward orreverse contactor locking induring jogging.The push button station canbe a Bulletin 800H, heavy duty,or a Bulletin 800T oiltight.Catalog Number 700-C200 re-lays may be used.

Starting, Stopping and Jogging in Either Direction. Jogging Controlled Through a Jogging Selector Switchi Here, the motor can run normally in either direction or can be jogged in either direction. With theselector in theRUN position, the motor can be started in either direction and will stop when the STOP button is pressed. It is

not necessary to press the STOP button before changing from forward to reverse.With the selector in the JOG position, the FORWARD and REVERSE buttons act as jogging buttons. Themotor will run in the indicated direction when one of them is pressed but will stop as soon as the button isreleased.

? The wiring of the standard Bulletin 505 must be modified for this type of operation. Note that the wires shownwith dotted lines must be removed from the standard starter. The push button station can be either a Bulletin800H heavy duty, or a Bulletin 800T, oiltight.

Plugging a Motor to a Stop from Either Direction- Lockout Solenoid Provided4 With the system wired as shown, the motor can be started in either direction by pressing the proper button.: Pressing the STOP button will plug the motor to a stop from either direction, A standard Bulletin 505 reversingswitch is used for this application.

The lockout solenoid is a built-in part of the Bulletin 808 Speed Switch and it guards against an accidental turnof the motor shaft closing the speed switch contacts and starting the motor. This protective feature is optionaland the speed switch can be furnished without lockout solenoid if desired.The control relay necessary with this system is a Catalog Number 700-8300 and the push button station can bea Catalog Number 800H-3HA or a Catalog Number 800T-3TA.

ANTI-PLUGGING- Motor Is to Be Reversed, but It Must Not Be PluggedA Bulletin 808 Speed Switch with normally closed contacts is used for anti-plugging. The schematic diagramshows that with the motor operating in one direction, a contact on the Speed Switch opens the control circuit ofthe starter used for the opposite direction. The open contact will not close until the motor has slowed down, andthus, the reversing switch cannot be energized to change the direction of the motor until the motor is movingslowly.A standard Bulletin 505 reversing switch can be used with this application. The push button station can be aCatalog Number 800S-3SA, or a Catalog Number 800H-3HA, or a Catalog Number 800T-3TA.
