Terminology
WIRING DIAGRAM
A wiring diagram shows, as closely as possible, the actual
location of all component parts of the device. The open
terminals (marked by an open circle) and arrows represent
connections made by the user.
Since wiring connections and terminal markings are
shown, this type of diagram is helpful when wiring the
device or tracing wires when troubleshooting. Bold lines
denote the power circuit and thin lines are used to show the
control circuit. Black wires are conventionally used in
power circuits and red wire in control circuits for AC
magnetic equipment.
A wiring diagram is limited in its ability to completely convey
the controller’s sequence of operation. The elementary
diagram is used where an illustration of the circuit in its
simplest form is desired.
ELEMENTARY DIAGRAM
An elementary diagram is a simplified circuit illustration.
Devices and components are not shown in their actual
positions. All control circuit components are shown as
directly as possible, between a pair of vertical lines
representing the control power supply. Components are
arranged to show the sequence of operation of the devices
and how the device operates. The effect of operating
various auxiliary contacts and control devices can be
readily seen. This helps in troubleshooting, particularly with
the more complex controllers.
This form of electrical diagram is sometimes referred to as
a “schematic” or “line” diagram.

Examples of Control Circuits
2- and 3-Wire Control
Elementary Diagrams
Low Voltage Release and Low Voltage Protection are the basic control circuits encountered in motor control applications. The simplest schemes
are shown below. Other variations shown in this section may appear more complicated, but can always be resolved into these two basic
schemes.
Note: The control circuits shown in this section may not include overcurrent protective devices required by applicable electrical codes. See page
11 for examples of control circuit overcurrent protective devices and their use.

PILOT DEVICE SUCH AS
LIMIT SWITCH,
PRESSURE SWITCH, ETC.
Low voltage release is a 2-wire control scheme using a
maintained contact pilot device in series with the starter coil.
This scheme is used when a starter is required to function
automatically without the attention of an operator. If a power
failure occurs while the contacts of the pilot device are closed,
the starter will drop out. When power is restored, the starter
will automatically pickup through the closed contacts of the
pilot device.
The term “2-wire” control is derived from the fact that in the
basic circuit, only two wires are required to connect the pilot
device to the starter.
Low voltage protection is a 3-wire control scheme using
momentary contact push buttons or similar pilot devices to
energize the starter coil.
This scheme is designed to prevent the unexpected starting of
motors, which could result in injury to machine operators or
damage to the driven machinery. The starter is energized by
pressing the Start button. An auxiliary holding circuit contact on
the starter forms a parallel circuit around the Start button
contacts, holding the starter in after the button is released. If a
power failure occurs, the starter will drop out and will open the
holding circuit contact. When power is restored, the Start button
must be operated again before the motor will restart.
The term “3-wire” control is derived from the fact that in the
basic circuit, at least three wires are required to connect the
pilot devices to the starter.

2-WIRE CONTROL DEVICE
A Hand-Off-Auto selector switch is used on 2-wire control
applications where it is desirable to operate the starter manually
as well as automatically. The starter coil is manually energized
when the switch is turned to the Hand position and is
automatically energized by the pilot device when the switch is
in the Auto position.

When a motor must be started and stopped from more than one
location, any number of Start and Stop push buttons may be
wired together. It is also possible to use only one Start-Stop
station and have several Stop buttons at different locations to
serve as an emergency stop.

A pilot light may be required to indicate when the motor is

illuminates. When the starter picks up, the auxiliary contact
opens, turning off the light.

As an operator safety precaution, a step-down transformer can
be used to provide a control circuit voltage lower than line
voltage. The diagram above shows one way to provide
overcurrent protection for control circuits.
A starter coil with a high VA rating may require a control transformer of considerable size. A control relay and a transformer with a low
VA rating can be connected so the normally-open relay contact
controls the starter coil on the primary or line side. Square D Size 5

FPO 7-1
Jogging, or inching, is defined by NEMA as the momentary
operation of a motor from rest for the purpose of accomplishing
small movements of the driven machine. One method of jogging
is shown above. The selector switch disconnects the holding
circuit contact and jogging may be accomplished by pressing the
Start push button.
A selector push button may be used to obtain jogging, as shown
above. In the Run position, the selector-push button provides
normal 3-wire control. In the Jog position, the holding circuit is
broken and jogging is accomplished by depressing the
push button.
Jogging: Control Relay
Jogging: Control Relay for Reversing Starter
FIG. 3
FIG. 4
FPO 7-4
FPO 7-3
When the Start push button is pressed, the control relay is
energized, which in turn energizes the starter coil. The normallyopen starter auxiliary contact and relay contact then form a
holding circuit around the Start push button. When the Jog push
button is pressed, the starter coil is energized (independent of the
relay) and no holding circuit forms, thus jogging can be obtained.
This control scheme permits jogging the motor either in the
forward or reverse direction, whether the motor is at standstill or
rotating. Pressing the Start-Forward or Start-Reverse push button
energizes the corresponding starter coil, which closes the circuit
to the control relay.The relay picks up and completes the holding
circuit around the Start button. As long as the relay is energized,
either the forward or reverse contactor remains energized.
Pressing either Jog push button will deenergize the relay,
releasing the closed contactor. Further pressing of the Jog button
permits jogging in the desired direction.

When one Start-Stop station is required to control more than one

3-wire control of a reversing starter can be implemented with a
Forward-Reverse-Stop push button station as shown above. Limit
switches may be added to stop the motor at a certain point in either
direction. Jumpers 6 to 3 and 7 to 5 must then be removed.

reverse contactor coils, indicating which contactor is energized
and thus which direction the motor is running.
3-Wire Control: 2-Speed Starter w/ 1 Pilot Light to
Indicate Motor Operation at Each Speed
FIG. 4
FIG. 3
3-wire control of a 2-speed starter with a High-Low-Stop push button
station is shown above. This scheme allows the operator to start the
motor from rest at either speed or to change from low to high speed.
The Stop button must be operated before it is possible to change from
high to low speed. This arrangement is intended to prevent excessive
line current and shock to motor and driven machinery, which results
when motors running at high speed are reconnected for a lower speed.
One pilot light may be used to indicate operation at both low and
high speeds. One extra normally-open auxiliary contact on each
contactor is required. Two pilot lights, one for each speed, may
be used by connecting pilot lights in parallel with high and low
coils (see reversing starter diagram above).
Plugging:
Plugging a Motor to a Stop from 1 Direction Only
Anti-Plugging:
Motor to be Reversed but Must Not be Plugged
FIG. 5
Plugging is defined by NEMA as a braking system in which the motor
connections are reversed so the motor develops a counter torque, thus
exerting a retarding force. In the above scheme, forward rotation of the
motor closes the normally-open plugging switch contact and
energizing control relay CR. When the Stop push button is operated,
the forward contactor drops out, the reverse contactor is energized
through the plugging switch, control relay contact and normally-closed
forward auxiliary contact. This reverses the motor connections and the
motor is braked to a stop. The plugging switch then opens and
disconnects the reverse contactor. The control relay also drops out.
The control relay makes it impossible for the motor to be plugged in
reverse by rotating the motor rotor closing the plugging switch. This
type of control is not used for running in reverse.
FIG. 6
Anti-plugging protection is defined by NEMA as the effect of a
device that operates to prevent application of counter-torque by
the motor until the motor speed has been reduced to an
acceptable value. In the scheme above, with the motor operating
in one direction, a contact on the anti-plugging switch opens the
control circuit of the contactor used for the opposite direction.
This contact will not close until the motor has slowed down, after
which the other contactor can be energized.

Shunting Thermal Units During Starting Period
FIG. 1
Article 430-35 of the NEC describes circumstances under
which it is acceptable to shunt thermal units during
abnormally long accelerating periods.
430-35. Shunting During Starting Period.
(a) Nonautomatically Started. For a nonautomatically
started motor, the overload protection shall be
permitted to be shunted or cut out of the circuit during
the starting period of the motor if the device by which
the overload protection is shunted or cut out cannot be
left in the starting position and if fuses or inverse time
circuit breakers rated or set at not over 400 percent of
the full-load current of the motor are so located in the
circuit as to be operative during the starting period of
the motor.
FPO 9-1
(b) Automatically Started. The motor overload protection
shall not be shunted or cut out during the starting
period if the motor is automatically started.
Exception. The motor overload protection shall be
permitted to be shunted or cut out during the starting period
on an automatically started motor where:
(1) The motor starting period exceeds the time delay
of available motor overload protective devices, and
(2) Listed means are provided to:
a. Sense motor rotation and to automatically
prevent the shunting or cut out in the event
that the motor fails to start, and
b. Limit the time of overload protection shunting
or cut out to less than the locked rotor time
rating of the protected motor, and
c. Provide for shutdown and manual restart if
motor running condition is not reached.
Figures 1 and 2 show possible circuits for use in
conjunction with 3-wire control schemes. Figure 1 complies
with NEC requirements. Figure 2 exceeds NEC
requirements, but the additional safety provided by the zero
speed switch might be desirable.
Figure 3 shows a circuit for use with a 2-wire, automatically
started control scheme that complies with NEC
requirements. UL or other listed devices must be used in
this arrangement.

Auxiliary contacts on contactors, relays and push button contacts
use 2-digit terminal designations, as shown in the diagram above.
The first digit indicates the location of the contact on the device. The
second digit indicates the status of the contacts, N.O. or N.C. “1”
and “2” indicate N.C. contacts. “3” and “4” indicate N.O. contacts.
96 98
With Non-Isolated
N.O. Alarm Contact
Overload contact terminals are marked with two digits. The first
digit is “9”. The second digits are “5” and “6” for a N.C. and “7” and
“8” for a N.O. isolated contact. If the device has a non-isolated
alarm contact (single pole), the second digits of the N.O. terminals
are “5” and “8”.

AC thru-beam emitter has no
output switching capability,
therefore leakage current is not
applicable. Thru-beam emitter is
connected directly across the AC
line and typically draws 15 mA.
Connect load in series. To prevent
damage, all switches except
emitters must have load
connected to switch.
2-Wire AC, Single Device Operation
AC Emitter

DC thru-beam emitter has no
output switching capability,
therefore it requires only a 2-wire
cable connected directly across
the DC. Thru-beam emitter draws
a maximum of 45 mA.
DC switches cannot be wired in
series. To prevent damage, all
switches except emitters must
have load connected to switch.

Average Efficiency and Power Factor Values of Motors:
When actual efficiencies and power factors of the motors to be controlled are not known, the following approximations may be used:
Efficiencies:
DC motors, 35 hp and less:
DC motors, above 35 hp:
Synchronous motors (at 100% PF):
80% to 85%
85% to 90%
92% to 95%
“Apparent” efficiencies (Efficiency x PF):
3-phase induction motors, 25 hp and less:
3-phase induction motors above 25 hp:
Decrease these figures slightly for single phase induction motors.
