Auxiliary contact
Basic motor control trms
Contact of a switching device in addition to the main circuit contacts and operated by the main contacts.
Line versus wiring diagram The line diagram is a simplified schematic of the circuit to show operation; it’s an ideal means for troubleshooting a circuit. The wiring diagram shows all of the devices in a circuit and their physical relationship to each other. Terminal connections for all components are identified to wire a complete circuit.
Two-wire control
Bimetal Two different metals bonded together provide fast heat transfer to trip contacts by mechanical deflection—used in thermal overload relays.
Contactor A device to repeatedly establish or interrupt an electric power circuit.
Full voltage control
Two-wire control is a control function that uses a maintained-contact type of pilot device to provide low voltage release (LVR).
Also across-the-line—connects equipment directly to line supply on starting.

To the right of the photograph is a wiring diagram of the same starter. Note the close relationship between the terminal connections on the starter and their counterpart in the wiring diagram.
The NO auxiliary contact (interlock) shown in the above wiring diagram is supplied as standard on Eaton Size 0 through 4 open type full voltage magnetic starters. In the diagrams throughout this document, the number and type of interlocks, and their physical location on the device will vary depending upon the equipment being discussed.
The black lines in the wiring diagram represent the power circuit— the incoming power lines, the internal power switching mechanism, and the outgoing motor leads. The red lines indicate the control circuit wiring required to switch power to the magnet coil for operation of the contactor.
In all cases, additional auxiliary contacts can be mounted on the starters when required. For specific information on the number and type of interlocks that can be added to a specific type of st arter, refer to the Eaton’s Control Products Catalog .

Control variations—multipl stations and local/rmot Multiple pushbutton stations operating a single starter
Local control with remote pushbutton station
Figur 13 is an arrangement that finds application where a single motor is to be operated from several different remote locations. The diagram also suggests other circuit possibilities including multiple emergency STOP stations. This type of control could be used in cases where the machine operator works in a location that is not within easy reach of the main pushbutton station.
When the starter must be operated from a remote pushbutton station as well as from local cover control, it can be accomplished as shown in Figur 14. Jumper wire X must be removed from the st arter when a remote pushbutton station is added.

Control variations—multipl startrs opratd from a singl pushbutton station Three starters operated from a single START/STOP station Figur 17 shows three Catalog Number AN16DN0AB starters for operation from a single standard three-wire START/STOP pushbutton station. The starters are wired so that if a maintained overload occurs on any one of the starters, all three will automatically be disconnected from the line. This is accomplished by wiring the holding circuit of each starter through the auxiliary contacts of one of the other two. As the control circuit is common between starters, incoming power lines to all three of the starters must be opened by a disconnect (fusible motor circuit switch, circuit breaker or safety switch) preceding each of the starters in order to completely disconnect the starters from the line.

Control variations—jogging Jogging with a control relay
Jogging with a selector switch
Jogging circuits as shown on this and following pages are primarily used where machines must be operated momentarily for inching, machine tool setup or for maintenance. The jog circuit permits the starter to be energized only as long as the JOG button is depressed, thereby giving the machine operator instantaneous control of the motor drive.
This circuit ( Figur 22) consists of a standard START/STOP pushbutton station and a two-position JOG/RUN selector switch. When the selector switch is in the JOG position, the main contactor coil remains closed only as long as the START button is depressed as the coil holding circuit is open. When the selector switch is in the RUN position, the START/STOP pushbutton station functions just as in a straight three-wire type of control circuit.
The circuit shown in Figur 21 consists of a single Catalog Number AN16DN0AB starter, a standard three element START/JOG/STOP pushbutton station and a control relay. The control or jog relay is used to prevent the main contactor coil from maintaining while the starter is being jogged. When the JOG button is depressed, the control relay is bypassed and the main contactor coil is energized solely through the JOG button. When the button is released, the contactor coil releases immediately. Pushing the START button closes the control relay and it is held in by its own NO contacts. The main contactor coil in turn is closed by another set of NO contacts on the control relay and is held in.

Control variations—jogging (continud) Jogging with “Roto-Push” selector pushbutton and START/STOP pushbutton station
Jogging with “Roto-Push” selector pushbutton and STOP button
The components used in this circuit ( Figur 23) include standard START/STOP pushbuttons and a “Roto-Push” selector pushbutton with a two-position JOG/RUN selector ring. When the selector ring is in the JOG position and the button is depressed, the main contactor coil is energized through the JOG button contacts. Because the auxiliary contacts on the starter are bypassed when the selector ring is in this position, the starter will remain closed only as long as the JOG button is held down. With the selector ring in the RUN position, the START/STOP pushbuttons function as a standard three-wire control station.
Figur 24 is basically the same circuit as in Figur 23 except that the start and jog functions are performed by a single button in the “Roto-Push” selector pushbutton element. When the selector ring is in the JOG position, the “Roto-Push” pushbutton will act as jog station and when the ring is in the RUN position, the button will operate as a standard START pushbutton station.

Control variations—two-wir control Pressure switch controls starter with RUN/OFF/AUTO selector switch for manual control Figur 25 shows a circuit commonly used for two-wire pressure switch control. A represents the low-pressure switch and B represents the optional high-pressure switch. The high-pressure switch is not essential to the operation of the st arter. It is strictly used as a safety precaution in case the low pressure switch fails to cut out when the proper pressure is obtained. The three-position selector switch, which is connected to bypass the low-pressure contacts, is used for manual control of the starter. The circuit illustrated can also be used for thermostat control. For this type of application, switch A is the thermostat and switch B is omitted.
Float switch controls starter Figur 26 shows a common single-pole, double-throw float switch of the type used in sump pump and tank filling applications. The circuit is shown connected (solid lines) for tank operation. For sump pump operation, the float switch should be connected as indicated by the dotted lines and connection A is omitted. In both cases, the float within the sump pump or tank controls the opening and closing of the contacts in the float switch, which in turn controls the motor starter.

Control variations—tim dlay and low voltag protction Two motor starters operated from a single START/STOP pushbutton station—time delay relay prevents them from starting together Incoming power line limitations in some areas prohibit the starting of two or more motors at the same time because of excessive starting loads. Where restrictions of this type occur, a time delay relay can be added between the control circuits of the starters to prevent them from energizing simultaneously. In this circuit ( Figur 27), when the START button is depressed, the M1 starter energizes and starts the M1 motor. At the same time the time delay relay, TR, is energized. After the timing cycle of TR is completed, the T.C. (timed close) contacts will close and energize the M2 starter and st art the M2 motor. If more than two starters are to be operated in this fashion, additional time delay relays, one for each starter, must be added for this type of application.

In locations where line disturbances are frequent, it is often necessary to provide low voltage protection for two-wire control devices. Where this protection is not provided, the starter will have a tendency to chatter when voltage drops occur in the incoming power lines. This chatter will result in subsequent damage to the starter contacts. It can be eliminated by the addition of a control relay as shown in the circuit located in Figur 28. When the starter is connected as indicated, a drop in line voltage will drop out the control relay and because the holding circuit of the main contactor coil of the starter is wired through the NO contacts of the control relay, the starter will also drop out. The starter will then remain open or de-energized until the control relay RESET button is depressed.

Control variations—pump opration Surge and backspin protection provided by a time delay relay
Surge and backspin protection both on starting and stopping
Two common considerations in pump control are surge and backspin protection. Surge protection is required where the column of water supported by the pump is prevented from flowing back through the line by a check valve when the pump is turned off. The closing of this valve can cause momentary surges of sufficient strength to operate the pressure switch and thus cause the starter to chatter. Backspin is the reverse flow of an unchecked column of water through the pump when the pump is turned off. The falling water will turn the pump motor in the opposite direction. Starting the motor under this condition could cause extensive damage to the windings.
This circuit (Figur 30),which includes a control relay and an OFF delay time delay relay in addition to the ON delay relay used in the circuit shown at left, provides surge protection on both starting and stopping, and automatic backspin protection.
Through the addition of a time delay relay as shown in Figur 29, both surge and backspin protection can be provided. When the pressure switch contacts close, the time delay relay is energized and the timing cycle starts. After the relay has timed out, the T.C. (timed close) contacts close and the motor starter is energized. A three-position selector switch has been added to give manual operation of the circuit.

When the pressure switch closes, the control relay, the starter, and the two time delay relays are energized. The instantaneous contact on TR 1 closes and bypasses the pressure switch contacts, preventing the starter from dropping out if the contacts open momentarily because of starting surges. After the timing cycle is completed, TR 1 opens the bypass allowing the pressure switch to stop the pump when the correct pressure is obtained. The OFF delay relay, TR 2, provides surge and backspin protection on stopping. When the pressure switch opens and the starter drops out, it cannot be restarted until TR 2 times out and its NC (normally closed) contact closes.

Control variations—squnc control Two starters arranged for conveyor type control system The two starters shown are arranged so that one cannot be started until the other is running. This type of control is necessary where one machine feeds a second machine, such as in a conveyor system. To prevent the No. 1 machine from piling up material on No. 2, the second machine is started first. This is accomplished simply by interconnecting the pushbutton stations as indicated in Figur 31. The control circuit of Motor No. 1 starter is wired through the auxiliary contact of Motor No. 2 starter, which prevents Motor No. 1 from st arting until after Motor No. 2 starter is energized. When standard Catalog Number AN16DN0AB starters are used, connection X must be removed from one of the starters as shown in Figur 31.

The circuit shown in Figur 32 can be used on applications where a second motor is to run for a short period of time after a controlling motor has stopped. An example would be a cooling fan or pump. Sequence control of this type is accomplished by the addition of an OFF delay relay to the circuit. When the START button is depressed, the M1 starter and the OFF delay relay are energized. The instantaneous NC contacts on the time delay relay, TR, open and prevent M2 from energizing. When the STOP button is depressed, M1 drops out and M2 picks up through the NC instantaneous contact and through the NC–TO (timed open) contacts of the OFF delay relay. M2 will remain energized until the relay times out and the NO–TO (timed open) contacts open the circuit.

Thr-phas magntic—control variations Pushbutton station wired for changing direction without pushing STOP button The pushbutton station when wired as shown, will permit immediate reversal of direction without first pushing the STOP button on the pushbutton station. Shown in Figur 39 is a separately mounted control circuit transformer to provide 120V control circuit voltage. The starter illustrated, Catalog Number ECN0711CAA, is supplied with a 120V magnet coil and is therefore wired for separate control. If limit switches are used, they can be connected as indicated in Figur 35 on Pag 22. Make sure to remove connections A and B from the st arter.
Pushbutton station with indicating lights Figur 40 is the same basic circuit as Figur 39 except that pilot lights have been added to indicate the direction of motor travel. The lights can either be mounted within the pushbutton enclosure or in a separate housing.

Thr-phas magntic—control variations (continud) Selector switch used to determine direction of motor travel
Limit switch used to control direction of motor travel
On applications where the motor and drive unit can not be seen from the control station, a visual indication of the direction of travel can be obtained by using a selector switch. Although indicating lights could be used for this t ype of application, this circuit ( Figur 41), has the advantage of fewer components.
Figur 42 shows a Catalog Number AN56DNV0B reversing starter controlled by a standard START/STOP pushbutton station and limit switch. The internal wiring of the starter is not modified for this control.
The START/STOP pushbutton station operates the same as on single direction motors with the setting of the selector switch determining the direction of the motor. If a standard Catalog Number AN56DNV0B reversing starter is used, the internal wiring must be altered slightly to accommodate this type of control. The two connections A and B must be removed from the starter and connections F and D must be added.
The START/STOP pushbutton station operates as a standard threewire control on a single direction motor. The direction of motor travel is determined by the electrical condition of the limit switch for this type of operation.

Thr-phas magntic—control variations, jogging Jogging with control relays
Jogging with a selector switch
Figur 43 is a st andard Catalog Number AN56DNV0B reversing starter connected for jogging or running in either direction. The circuit includes a five-element pushbutton station and two control relays. Operation is straightforward with the jogging relays used to prevent the main contactor coils from locking in during jogging. This is one of the most widely used control circuits for this particular type of application.
A simpler and more economical method for jogging or running in either direction is accomplished by using a selector switch and a three-element FORWARD/REVERSE/STOP pushbutton station. When the selector switch is in the JOG position, the FORWARD and REVERSE pushbuttons will energize the main contactor coils only as long as they are held depressed. With the selector ring in the RUN position, the FORWARD and REVERSE buttons will operate as a standard pushbutton station.
The internal wiring of the st andard Catalog Number AN56DNV0B starter does not have to be altered when using this type of control.

Thr-phas magntic—control variations, jogging (continud) Jogging with two “Roto-Push” selector pushbuttons and a STOP button This circuit (Figur 45) for jogging or running in either direction consists of t wo “Roto-Push” selector pushbutton elements and a STOP button. Each of the “Roto-Push” elements has a twoposition JOG/RUN selector ring. The operation of the FORWARD and REVERSE “Roto-Push” pushbutton stations is electrically and mechanically the same. With the selector ring in the RUN position, depressing the button energizes the main contactor coil that holds in through its own auxiliary contacts.
The starter is dropped out by depressing the STOP button. With the selector ring in the JOG position, the main contactor coil is energized through the contacts of the JOG button and the holding circuit to the coil is cammed open. The coil will remain energized only as long as the button is held depressed. Mechanical and electrical interlocks between the t wo contactors prevent them from energizing simultaneously.

aC ducd vlg—mgc Part-winding typ—two-point acclration, for part-winding wy connctd motors Part winding type The Catalog Number ECN45 part-winding type reduced voltage starter is a two-step accelerating starter for use with a half-winding wye connected full voltage motor or a six-lead delta connected dual voltage motor used on the lower voltage. It is equipped with two contactors, a time delay NO relay, and t wo three-coil thermal overload relays, one for each connection.
During starting, the “1M” contactor is energized first and power is applied to motor terminals T1, T2, and T3. After the time delay NO auxiliary interlock on “1M” has timed out and the T.C. (timed close) contacts close, the “2M” contactor is energized connecting power to the second winding, motor terminals T7, T8, and T9. The motor is stopped by depressing the STOP button, which drops out both contactors.
The total full load motor current of the wye connected part-winding type motor is divided approximately equally between two sets of windings with each winding handling half or 50% of full power. Each of the two contactors within the starter is connected to one set of these windings.
If motor terminals T4, T5, and T6 are not internally connected, they should be wired together at the terminal box as indicated by the dotted “power” lines at the motor.
