Overload Relay Features
Trip Relay
When the E3 Overload Relay is in the unpowered state, the trip relay contact is
open. The trip relay contact closes approximately 2 to 35 seconds after power is
applied if no trip condition exists.
Inputs & Outputs
In addition to the trip relay, the E3 Overload Relay provides inputs and outputs as
shown below.
Table 1 - Inputs & Outputs
ModelInputs ➊Outputs
EC121
EC2, EC342
EC5 62
➊ Inputs are rated at 24V only. For 120V AC inputs, add the AC Input Interface Module, Cat. No. 193-EIMD.
The status of each input and output can be monitored over the DeviceNet
network through Device Status, Parameter 21, or one of the input assemblies.
Additionally, the outputs can be controlled over the network using one of the
output assemblies. Refer to Appendix B for listings of the available input and
output assemblies.
Series B and later E3 Plus Overload Relays offer added flexibility by providing the
capability to perform control functions with the inputs and outputs through
DeviceLogix™.
Series B or later E3 Overload Relay inputs are independently configurable for trip
reset, remote trip, two-speed, and normal operation.
ATTENTION: If the outputs are being commanded via an explicit
message, ensure that there is no established I/O connection that is
actively controlling the outputs and that the explicit message connection
has a non-zero expected packet rate (EPR) setting.
ATTENTION: The state of the outputs during a protection fault,
DeviceNet communication fault, or a DeviceNet communication idle may
be dependent on the following OUT A or OUT B parameters: PrFltState, Pr
FltValue, Dn FltState, Dn FltValue, Dn IdlState, and Dn IdlValue. For
details, refer to the Output Setup Group section in Chapter 5.
14Rockwell Automation Publication 193-UM002I-EN-P - December 2011
Product Overview Chapter 1
ATTENTION: The E3 Overload Relay’s output control firmware latches
OUT A and OUT B closed upon receipt of a network close command. The
outputs will maintain the commanded closed state until receipt of a
network open command. Parameters OutX Pr FltState and OutX Pr
FltValue, found in the E3 Overload Relay’s output setup group, allows
flexibility concerning the operation of the outputs in the event of a trip.
Factory default settings cause the outputs to open upon
occurrence of a trip. E3 outputs that were closed prior to a trip
will reclose upon trip reset, provided that a network open
command is not received first.
User Interface
Refer to Figure 1 on page 11 for the location of LED status indication, Test/Reset
button, and node address switches.
LED Status Indication
The following LED status indicators are provided on the E3 Overload Relay. See
Chapter 12 for detailed information on each status.
Network Status — Illuminated in green or red, this indicates the network
connection status.
Tr ip / Wa rn i ng — Under a warning condition, the LED status flashes a sequence
of red and/or amber. Under the trip condition, the LED status flashes a sequence
of red. In either condition, the flash pattern followed by a pause identifies the
specific trip or warning. The meaning of the flash pattern can be found on the E3
Overload Relay’s side label or Table XX on page XX.
OUT A and OUT B — When the output contacts are commanded closed, the
LED illuminates amber.
IN 1…IN 4 —When the user-connected device contact is closed, the LED status
illuminates in amber.
NOTE: IN 3, IN 4, and OUT B are available only on the E3 Plus Overload Relay.
Test/Reset ButtonT
Tes t — If Test Enable is activated, the trip relay contact will open if the E3
Overload Relay is in an untripped condition and the Test/Reset button is
pressed. For devices with firmware revision number (FRN) 2.000 and later, the
Test/Reset button must be pressed for a minimum of two seconds to activate the
test function.
Reset — If the E3 Overload Relay (a) is in a tripped condition, (b) the cause of

the trip is no longer present, and (c) the test/reset button is pressed, the trip relay
contact will close.
ATTENTION: The Test function associated with the Test/Reset button is
enabled by default. Activating the Test function while a motor is operating
will cause the starting contactor to drop out and stop motor operation.
Node Address Switches
The node address switches, located on the front of the Series B and later E3
Overload Relays, provide a physical means for setting the device node address
value. Switch settings greater than 63 allow the node address to be software
configured.

ATTENTION: When working on energized circuits, DO NOT rely on
voltage and current information provided by the E3 and E3 Plus Overload
Relay for personal safety. Always use a portable voltage or current
measurement device to measure the signal locally.
Single/Three Ph, Parameter 27, should be set to single-phase.
Traditional single-phase wiring connecting T2 to L3 will result in a vector
imbalance of current flowing through the E3 Plus Overload Relay. This
will result in inaccurate ground fault reporting and protection.

mounted, customer-supplied, line current transformers (CTs) as required in
higher-current applications. The FLA setting range is 9…5000 A for these units
with a legal setting range per current transformer. CT Ratio, Parameter 78, is
provided for setting the current transformer ratio to be installed.
Specifications
The 193-EC_ZZ Overload Relays are intended for use with CTs having a
secondary current rating of 5 A. The installer shall (1) provide one CT for each
motor phase and shall (2) connect the CT’s secondary leads to the appropriate E3
Installation & Wiring Chapter 2
Overload Relay power terminals as shown in Figure 14 on page 36. The CTs shall
have an appropriate ratio rating as detailed in Table 18.
Additionally, the CT shall be selected to be capable of providing the required VA
to the secondary load, which includes the E3 Overload Relay burden of 0.1 VA at
the rated secondary current and the wiring burden.
Finally, the CT shall (1) be rated for Protective Relaying to accommodate the
high inrush currents associated with motor startup and shall (2) have an accuracy
≤±2% over its normal operating range. Typical CT ratings include:
of
• ANSI USA
• CSA (Canada)
• IEC (Europe)
ATTENTION: The improper selection of a current transformer can result
in the E3 Overload Relay reporting inaccurate motor operational data and
possible motor damage. The selected current transformer must be rated
for protective relaying applications.
• Class C5 BO.1
• Class 10L5
• 5 VA Class SP10
Installation Requirements
• The 193-EC_ZZ Overload Relays are designed to be installed in193ECPM2 Panel Mount Adapters and connected to separately mounted
current transformers.
• For 193-ECPM2 Panel Mount Adapter assembly, refer to the instructions
included with the panel mount adapter.
ATTENTION: Placing the E3 Overload Relay closer than the
recommended distance, six times the cable diameter (including
insulation), may compromise its current reporting and protection
capabilities.
• The E3 Overload Relay must be mounted a distance equal to or greater
than six times the cable diameter (including insulation) from the nearest
current-carrying conductor or current transformer.
• For applications employing multiple conductors per phase, the diameter of
each cable should be added and multiplied by six to determine the proper
placement distance for the E3 Overload Relay.

The 193-EC3_ _ E3 Plus Overload Relays are intended to provide ground fault
protection when used with the external 193-CBCT_ Core Balanced Ground
Fault Sensor. The ground fault sensor mounts separately from the E3 Plus
Overload Relay and must be placed within three meters of the E3 Plus Overload
Relay. The customer-supplied power cable for wiring the ground fault sensor to
the E3 Plus Overload Relay must meet the specifications outlined in Ta bl e 7 o n
page 28.
Power Cable Installation Requirements
• All power cables (including the neutral when used) must pass through the
sensor window. The equipment ground conductor (the conductor used to
carry the non-current-carrying metal parts of equipment, as defined by
Article 100 of the NEC) must not pass through the sensor window.
• The power cables through the sensor window should be straight, tightly
bundled, centered in the window, and perpendicular to the sensor for a
length equal to or greater than six times the cable diameter (including
insulation) from the sensor.
• All other conductors with available fault currents in excess of 1,000 A
should be placed a distance equal to or greater than six times the cable
diameter (including insulation) from the sensor.
• The power cables of the branch circuit to be protected by the E3 Plus
Overload Relay must not be grounded on the load side of the ground fault
sensor.

• If the power cables are enclosed in a conducting jacket, the jacket must be
grounded on the line side of the sensor. The jacket must not pass through
the sensor window, but must be cut at the window and joined with a
conductor that passes outside the sensor window.
• The power system may be solidly grounded or grounded through an
impedance at its source as long as the impedance allows a magnitude of
current to flow that is within the 20 mA…5 A operational range of the E3

ATTENTION: Do not exceed the ratings of the E3 Overload Relay’s
output and trip relay. If the coil current or voltage of the contactor exceeds
the overload relay’s ratings, an interposing relay must be used.
ATTENTION: When the power is applied to the E3 Overload Relay,
DeviceNet terminals V+ and V-, the N.O. trip relay contact across
terminals 95 and 96 will close after approximately 2.35 seconds if no trip
condition exists.
ATTENTION: Additional control circuit protection may be required. Refer
to the applicable electrical codes.

Introduction
Trip Enable
The purpose of this chapter is to provide detailed information regarding the
protective trip and warning functions of the E3 Overload Relay. In this chapter,
you will find considerable mention given to programming parameters as they
relate to these functions. For complete descriptions of the programming
parameters, refer to Chapter 5—Programmable Parameters.
Trip Enable, Parameter 24, allows the installer to enable or disable the desired
protective functions separately. The overload, phase loss, and communication
fault trip functions are enabled from the factory.
The E3 Overload Relay requires overload trip protection to be enabled at
all times. The E3 Plus Overload Relay requires either overload or PTC trip
protection to be enabled at all times.
ATTENTION: To avoid unexpected behavior of the outputs, the Trip
Enable settings should not be altered during the machine operation.
Doing so may result in an unintended actuation of controlled industrial
equipment with potential for machine damage or serious injury to
personnel.
Warning Enable
Overload Protection
Warning Enable, Parameter 25, allows the installer to enable or disable the desired
warning functions separately. All warning functions are disabled from the factory.
The E3 Overload Relay provides overload protection through true RMS current
measurement of the individual phase currents of the connected motor. Based on
the maximum current measured and the programmed FLA Setting and Trip
Class, a thermal model that simulates the actual heating of the motor is
calculated. The percent thermal capacity utilized, Parameter 9, reports this
calculated value and can be read via the DeviceNet network.
Overload Trip
The E3 Overload Relay will trip with an overload indication if:
• no trip currently exists,
• overload protection is enabled, and
Rockwell Automation Publication 193-UM002I-EN-P - December 201145
Chapter 3 Protective Trip & Warning Functions
IMPORTANT
• % Therm Utilized reaches 100%.
If the E3 Overload Relay trips on an overload, the following will occur:
• the TRIP/WARN LED will flash a red two-blink pattern,
• Bit 1 in Trip Status, Parameter 14, will go to “1”,
• Bit 0 in Device Status, Parameter 21, will go to “1”,
• the Trip Relay contact will open, and
• the outputs will be placed in their Protection Fault state (if so
programmed).
The Protection Fault State of OUT A and OUT B is defined by:
• OUTA Pr FltState, Parameter 65
• OUTA Or FltValue, Parameter 66
• OUTB Pr FltState, Parameter 71
• OUTB Pr FltValue, Parameter 72
FLA Setting
The FLA Setting, Parameter 28, is provided for the installer to enter the motor’s
full-load current rating. The 2-SpdFLA Set, Parameter 88, is provided in series B
and later E3 Plus Overload Relay units for programming the high-speed FLA
values in two-speed motor applications. The FLA Setting ranges and default
values for the various E3 Overload Relays can be found in Chapter 5—Programmable Parameters. Below are setting guidelines regarding service
factor, maximum continuous rated (MCR) motors, and wye-delta (star-delta)
motors.
USA & Canada Guidelines
• Motor Service Factor ≥ 1.15: For motors with a service factor rating of
1.15 or greater, program the FLA setting to the printed nameplate’s fullload current rating.
• Motor Service Factor < 1.15: For motors with a service factor rating less
than 1.15, program the FLA setting to 90% of the printed nameplate’s fullload current rating.
• Wye-Delta (Y-Δ) Applications: Follow the application’s service factor
instructions, except divide the printed nameplate’s full-load current rating
by 1.73.
Outside USA & Canada Guidelines
• Maximum Continuous Rated (MCR) Motors: Program the FLA setting
to the printed nameplate’s full-load current rating.
• Star-Delta (Y-Δ) Applications: Follow the MCR instructions, except
divide the printed nameplate’s full-load current rating by 1.73.

CT Ratio
Devices with the FLA setting range of 9…5000 A (Cat. No. 193-EC_ZZ) are
intended for use with primary current transformers. CT Ratio, Parameter 78,
allows the installer to identify the turns ratio of the transformers(s) in use. Each
CT Ratio selection has a corresponding valid FLA setting range, as described in
the following table.

Auto/Manual Reset
OL/PTC ResetMode, Parameter 30, allows the user to select the reset mode for
the E3 Overload Relay after an overload or thermistor (PTC) trip. If an overload
trip occurs and automatic reset mode is selected, the E3 Overload Relay will
automatically reset when the value stored in % Therm Utilized, Parameter 9, falls
below the value stored in OL Reset Level, Parameter 31. If manual reset mode is
selected, the E3 Overload Relay can be manually reset after the % Therm Utilized
is less than the OL Reset Level.
OL Reset Level, Parameter 31, is adjustable from 1 to 100% TCU. The following
table illustrates the typical overload reset time delay when OL Reset Level is set to
75% TCU.

Overload Warning
The E3 Overload Relay will indicate an overload warning if:
• no warning currently exists,
• overload warning is enabled, and
• % Therm Utilized is equal to or greater than OL Warn Level.
When the overload warning conditions are satisfied, the:
• TRIP/WARN LED status indicator will flash an amber 2-blink pattern,
• Warning Status, Parameter 15, will set to 1, and
• Device Status, Parameter 21, will set to 1.
OL Warn Level, Parameter 32, can be used as an alert for impending overload trip
and is adjustable from 0…100% TCU.

Protective Trip & Warning Functions Chapter 3
Overload Diagnostics
Time to Trip
When the measured motor current exceeds the trip rating of the E3 Overload
Relay, the Time to Trip, Parameter 12, indicates the estimated time remaining
before an overload trip occurs. When the measured current is below the trip
rating, the Time to Trip value is reported as 9,999 seconds.
Time To Reset
After an overload trip, the E3 Overload Relay will report the time remaining until
the device can be reset through Time to Reset, Parameter 13. Once the % Therm
Utilized value falls to or below the OL Reset Level, the Time to Reset value will
indicate zero until the overload trip is reset. After an overload trip is reset, the
Time to Reset value is reported as 9,999 seconds.
Phase Loss Protection
Non-Volatile Thermal Memory
The E3 Overload Relay includes a non-volatile circuit to provide thermal
memory. The time constant of the circuit corresponds to a Trip Class 30 setting.
During normal operation, the thermal memory circuit is continually monitored
and updated to accurately reflect the thermal utilization of the connected motor.
If power is removed, the thermal memory of the circuit decays at a rate equivalent
to the cooling of a Trip Class 30 application. When the power is re-applied, the
E3 Overload Relay checks the thermal memory circuit voltage to determine the
initial value of % Therm Utilized, Parameter 9.
A high current imbalance, or phase failure, can be caused by defective contacts in
a contactor or circuit breaker, loose terminals, blown fuses, sliced wires, or faults
in the motor. When a phase failure exists, the motor can experience an additional
temperature rise or excessive mechanical vibration. This may result in a
degradation of the motor insulation or increased stress on the motor bearings.
Rapid phase loss detection helps to minimize the potential damage and loss of
production.
Phase Loss Trip
The E3 Overload Relay will trip with a phase loss indication if:
• no trip currently exists,
• Phase Loss Protection is enabled,
• PL Inhibit Time has expired, and
Rockwell Automation Publication 193-UM002I-EN-P - December 201151

IMPORTANT
IMPORTANT
• Current Imbal is equal to or greater than 100% for a time period greater
than the programmed PL Trip Delay.
If the E3 Overload Relay trips on a phase loss, the:
• TRIP/WARN LED status indicator will flash a red 3-blink pattern,
• bit 2 in Trip Status, Parameter 14 will set to 1,
• bit 0 of Device Status, Parameter 21, will set to 1,
• trip relay contact will be open, and
• outputs will be placed in their Protective Fault state (if so programmed).
The Protection Fault State of OUT A and OUT B is defined by:
• OUTA Pr FltState, Parameter 65,
• OUTA PrFltValue, Parameter 66,
• OUTB Pr FltState, Parameter 71, and
• OUTB Pr FltValue, Parameter 72.
PL Inhibit Time, Parameter 33, allows the installer to inhibit a phase loss trip
from occurring during the motor starting sequence. It is adjustable from 0…250
seconds.
Ground Fault Protection (E3
Plus)
PL Trip Delay, Parameter 34, allows the installer to define the time period for
which a phase loss condition must be present before a trip occurs. It is adjustable
from 0.1…25.0 seconds.
The phase loss inhibit timer starts after the maximum phase of load current
transitions from 0 A to 30% of the device’s minimum FLA Setting. The E3
Overload Relay does not begin monitoring for a phase loss condition until
the PL Inhibit Time expires.
In isolated or high impedance-grounded systems, core-balanced current sensors
are typically used to detect low level ground faults caused by insulation
breakdowns or entry of foreign objects. Detection of such ground faults can be
used to interrupt the system to prevent further damage or to alert the appropriate
personnel to perform timely maintenance.
The E3 Plus Overload Relay provides core-balanced ground fault detection
capability, with the option of enabling Ground Fault Trip, Ground Fault
Warning, or both. The ground fault detection method and range depends upon
the catalog number of the relay ordered.

a ground fault condition until the GF Inhibit Time expires.
Ground Fault Trip Inhibit
Ground faults can quickly rise from low-level arcing levels to short circuit
magnitudes. A motor starting contactor may not have the necessary rating to
interrupt a high magnitude ground fault. In these circumstances it is desirable for
an upstream circuit breaker with the proper rating to interrupt the ground fault.
NOTE:The GF Trip Inhibit feature is only available in E3 Plus Overload Relays Series
B and later.

IMPORTANT
When enabled, GF Trip Inhibit, Parameter 89, inhibits a ground fault trip from
occurring when the ground fault current exceeds the maximum range of the core
balance sensor (approximately 10 A).
Ground Fault Warning
The E3 Plus Overload Relay will indicate a ground fault warning if:
• no warning currently exists,
• ground fault warning is enabled,
• GF Inhibit Time has expired, and
• GF Current is equal to or greater than the GF Warn Level (Series C and
later devices) for a time period greater than the GF Warn Delay.

adjustable from 1.0…5.0 A.
In Series C and later, GF Warn Delay, Parameter 105, allows the installer to
define the time period (adjustable from 0.0…25.0 s) for which a ground fault
condition must be present before a warning occurs.
In E3 Plus Overload Relay Series A and B, the ground fault warning
function does not include a time delay feature. Once the GF Inhibit Time
has expired, the ground fault warning indication is instantaneous.
Ground Fault Filter
An E3 Plus Overload Relay with firmware revision 5.00 and higher has the
capability to filter ground fault currents for High Resistance Grounded (HRG)
systems from its current-based protection trip and warning functions. These
filters include: Thermal Overload, Phase Imbalance, Jam, and Stall.
The Ground Fault Filter is useful for smaller-sized motors that trip unexpectedly
due to a controlled ground fault current that is significant relative to the current
draw of the electric motor. GF Filter Enable, Parameter 131, allows the user to
enable this filter.
This filter only disables the effects of the ground fault current from the currentbased motor protection trip and warning functions. Current-based diagnostic
data will be reported unfiltered when this feature is enabled.

Stall Protection
When a motor stalls during its starting sequence, the motor heats up very rapidly.
After the permissible stalling time, the motor reaches the temperature limit of its
insulation. Rapid stall detection during the starting sequence can extend the
motor’s life, as well as minimize potential damage and loss of production.
Stall Time
The E3 Overload Relay will trip with a stall indication when:

• OUTA Pr FltState, Parameter 65
• OUTA Pr FltValue, Parameter 66
• OUTB Pr FltState, Parameter 71
• OUTB Pr FltValue, Parameter 72
Stall Enabled Time, Parameter 39, allows the installer to adjust the time the E3
Overload Relay monitors for a stall condition during the motor starting sequence
and is adjustable from 0…250 seconds.
Stall Trip Level, Parameter 40, allows the installer to define the locked rotor
current and is adjustable from 100…600% of the FLA Setting, Parameter 28.
Stall Protection is only enabled during the motor starting sequence. If the
maximum phase of load current falls below the programmed Stall Trip
Level before the Stall Enabled Time elapses, the E3 Overload Relay
disables Stall Protection until the next motor starting sequence.
The E3 Overload Relay considers a motor to have begun its starting
sequence if the maximum phase of motor current transitions from 0 A to
approximately 30% of the minimum FLA Setting.

Motor current less than a specific level may indicate a mechanical malfunction in
the installation, such as a torn conveyor belt, damaged fan blade, broken shaft, or
worn tool. Such conditions may not harm the motor, but they can lead to loss of
production. Rapid underload fault detection helps to minimize damage and loss
of production.

Thermistor/PTC Protection
The E3 Plus Overload Relay models -EC2 and -EC3 provide terminals IT1 and
IT2 for the connection of positive temperature coefficient (PTC) thermistor
sensors. PTC sensors are commonly embedded in motor stator windings to
monitor the motor winding temperature. When the motor winding temperature
reaches the PTC sensor’s temperature rating, the PTC sensor’s resistance

Protective Trip & Warning Functions Chapter 3
IMPORTANT
Preventive Maintenance
Diagnostics (E3 Overload
Relays Series C & Later)
The purpose of this section is to provide detailed information regarding the
Preventive Maintenance Diagnostic functions of the E3 Overload Relays Series C
and Later. In this section programming and monitoring parameters as they relate
to these functions will be discussed. For complete descriptions of the
programming parameters, Refer to Programmable Parameters on page 105.
Monitoring
Elapsed Time, Parameter 95, logs the hours of motor operation — the time
period that the E3 Overload Relay is sensing motor current present (must be
greater than 30% of the minimum Full Load Current (FLA) setting).
Starts Counter, Parameter 96, logs the number of starts — the number of times
motor current transitions from zero to a reported non-zero value (motor current
must be greater than 30% of the minimum Full Load Current (FLA) setting).
The E3 Overload Relay will report 0 A or 0% FLA if the current is below
30% of the minimum FLA setting.
Start Inhibit
This protective function allows the installer to limit the number of starts in a
given time period. A start is defined as the E3 Overload Relay sensing a transition
in current from zero to a reported non-zero value (motor current must be greater
than 30% of the minimum Full Load Current (FLA) setting). The Start Inhibit
protective function can be set by: Starts/Hour and/or Starts Interval.
Start Inhibit Trip
The E3 Overload Relay will trip with a Blocked Start indication upon motor
stopping when:
• no trip currently exists,
• Start Inhibit is enabled,
• the number of starts count within the past hour period equals the value set
in the Starts/Hour parameter, or
• the time expired since the most recent start is less than the value set in the
Starts Interval parameter.
If the E3 Overload Relay trips on a Blocked Start, the:
• TRIP/WARN LED will flash a red 16-blink pattern,
• bit 15 in Trip Status, Parameter 14, will set to “1”,
• bit 0 in Device Status, Parameter 21, will set to “1”,
• Trip Relay contact will be open, and

• outputs will be placed in their Protection Fault state (if so programmed).
The Protection Fault State of OUT A and OUT B is defined by:
• OUTA Pr FltState, Parameter 65
• OUTA Pr FltValue, Parameter 66
• OUTB Pr FltState, Parameter 71
• OUTB Pr FltValue, Parameter 72
Starts/Hour, Parameter 99, allows the installer to limit the number of starts per
hour. It is adjustable from 1…120.
Starts Interval, Parameter 100, allows the installer to limit the time between
starts. It is adjustable from 0…3600 seconds.
Starts Available, Parameter 97, reports the number of starts currently available
based on the Start Inhibit settings and the actual motor starting events.
Time to Start, Parameter 98, reports the amount of the time remaining until a
new start can be effected. If the Time to Start time has elapsed, it will report zero
until the next Blocked Start trip occurs.
Preventive Maintenance Flags
The E3 Overload Relay offers preventive maintenance flags in the Warning Status
parameter based on the number of start cycles or the number of operating hours
(motor current must be greater than 30% of the minimum Full Load Current
(FLA) setting). These can be used to send the user a warning message that the
number of starts or number of operating hours has been reached and that it is
time to perform preventive maintenance. The preventive maintenance warning
function can be set by PM - # Starts and/or PM – Oper. Hours.
The E3 Overload Relay will report 0 A or 0% FLA if the current is below
30% of the minimum FLA setting.
PM - # Starts, Parameter 101, allows the installer to set a number of starts. It is
adjustable from 0…65,535.
The E3 Overload Relay will give a PM - # Starts warning indication when:
• PM - # Starts warning is enabled and
• Starts Counter parameter is equal to or greater than the value set in the PM
- # Starts parameter.
Upon a PM - # Starts warning, the:
• TRIP/WARN LED will flash an amber 14-blink pattern,
• bit 13 in Warning Status, Parameter 15, will set to “1”, and
• bit 1 in Device Status, Parameter 21, will set to “1”.

Protective Trip & Warning Functions Chapter 3
PM – Oper. Hours, Parameter 102, allows the installer to set a number of hours
of operation. It is adjustable from 0…65,565 hours.
The E3 Overload Relay will give a PM – Oper. Hours warning indication when:
• PM – Oper. Hours warning is enabled, and
• Elapsed Time parameter is equal to or greater than the value set in the PM
– Oper. Hours parameter.
Upon a PM – Oper. Hours warning, the:
• TRIP/WARN LED will flash an amber 15-blink pattern,
• bit 14 in Warning Status, Parameter 15, will set to “1”, and
• bit 1 in Device Status, Parameter 21, will set to “1”.
Queue Clearing
Using the Clear Queue, Parameter 104, the E3 Overload Relay provides the
capability to simultaneously clear/reset the:
• Trip Logs, Parameters 16…20,
• Warning Logs, Parameters 90…94,
• Starts Counter, Parameter 96, and the
• Elapsed Time Parameter 95.
If using the Preventative Maintenance Flags, the user will want to reset the Starts
Count and Elapsed Time after preventative maintenance has been performed.

DeviceNet™ Node Commissioning
IMPORTANT
The following recommendations are intended to ensure a trouble-free
startup and operation:
• Use the node commissioning tool in RSNetWorx™ or the E3
programming and control terminal when modifying the E3 Overload
Relay’s node address. Do not use the “General” tab found in the
product window in RSNetWorx. The node commissioning tool ensures
that the device goes through a hard reset and requires the user to
upload the most current parameter information from the device prior
to making configuration changes.
• Ensure that you have the most current configuration information prior
to saving a RSNetWorx configuration file.
• If you intend to employ the automatic device recovery (ADR) function
of the DeviceNet scanner, ensure that the device configuration is as
you intend it before saving to memory.
• Be aware that the “Restore Device Defaults” button in RSNetWorx
will reset the E3 Overload Relay’s node address setting to 63. For
Series B and later devices, the hardware node address switches take
precedence over the software node address setting.
Chapter

Introduction
E3 Overload Relays are shipped with a default software node address (MAC ID)
setting of 63 and the data rate set to Autobaud. Each device on a DeviceNet
network must have a unique node address which can be set to a value from 0 to
63. Keep in mind that most DeviceNet systems use address 0 for the master
device (Scanner) and node address 63 should be left vacant for introduction of
new slave devices. The node address and data rate for Series B and later E3
Overload Relays can be changed using software or by setting the hardware
switches that reside on the front of each unit. While both methods yield the same
result, it is a good practice to choose one method and deploy it throughout the
system.
Setting the Hardware Switches (Series B & Later)
Use the following steps to commission the card.
1. Set the node address switches. Use the table below to assist you.
