Overload Relay Features
Trip Relay
When the CEP7 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 CEP7 Overload Relay provides inputs and
outputs as shown below.

➊ Inputs are rated at 24V only. For 120V AC inputs, add the AC Input Interface Module, Cat. No. CEP7-EIMD.
The status of each input and output can be monitored over the DeviceNet
network through Device Status, Parameter 21, r 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 CEP7 Overload Relays offer added flexibility by providing the
capability to perform control functions with the inputs and outputs through
DeviceLogix™.
Series B or later CEP7 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.
14
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
Product Overview
Chapter 1
ATTENTION: The CEP7 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 CEP7 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. CEP7 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 CEP7 Overload Relay.
See Chapter 12 for detailed information on each status.
Network Status — Illuminated in green or red, this indicates the network
connection status.
Trip/Warning — 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
CEP7 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 CEP7 Overload Relay.
Test/Reset ButtonT
Test — If Test Enable is activated, the trip relay contact will open if the CEP7
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 CEP7 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 CEP7
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.

Installation & Wiring
Introduction
This chapter provides instructions for receiving, unpacking, inspecting, and
storing the CEP7 Overload Relay. Installation and wiring instructions for
common applications are also included.
Receiving
It is the responsibility of the user to thoroughly inspect the equipment before
accepting the shipment from the freight company. Check the item(s) received
against the purchase order. If any items are damaged, it is the responsibility of the
user not to accept delivery until the freight agent has noted the damage on the
freight bill. Should any concealed damage be found during unpacking, it is again
the responsibility of the user to notify the freight agent. The shipping container
must be left intact and the freight agent should be requested to make a visual
inspection of the equipment.
Unpacking/Inspecting
Remove all packing material from around the CEP7 Overload Relay. After
unpacking, check the item’s nameplate catalog number against the purchase
order.
Storing
The CEP7 Overload Relay should remain in its shipping container prior to
installation. If the equipment is not to be used for a period of time, it must be
stored according to the following instructions in order to maintain warranty
coverage:
• Store in a clean, dry location.
• Store within an ambient temperature range of -40 °C…+85 °C
(-40 °F…+185 °F).
• Store within a relative humidity range of 0…95%, non-condensing.
• Do not store where the device could be exposed to a corrosive atmosphere.
• Do not store in a construction area.

General Precautions
In addition to the specific precautions listed throughout this manual, the
following general statements must be observed.
ATTENTION: The CEP7 Overload Relay contains electrostatic discharge
(ESD) sensitive parts and assemblies. Status control precautions are
required when installing, testing, servicing, or repairing this assembly.
Component damage may result if ESD control procedures are not
followed. If you are not familiar with static control procedures, refer to
Allen-Bradley publication 8000-sb001_-en-p, Guarding Against
Electrostatic Damage”, or any other applicable ESD protection handbook.
ATTENTION: An incorrectly applied or installed CEP7 Overload Relay can
result in damage to the components or reduction in product life. Wiring or
application errors (e.g., incorrectly figuring the FLA setting, supplying
incorrect or inadequate DeviceNet supply voltage, connecting an external
supply voltage to the input or thermistor terminals, or operating.storing in
excessive ambient temperatures) may result in malfunction of the CEP7
Overload Relay.
ATTENTION: Only personnel familiar with the CEP7 Overload Relay and
associated machinery should plan to install, start up, and maintain the
system. Failure to comply may result in personal injury or equipment
damage.
ATTENTION: The purpose of this user manual is to serve as a guide for
proper installation. The National Electrical Code (NEC) and any other
governing regional or local code will overrule this information. Rockwell
Automation cannot assume responsibility for the compliance or proper
installation of the CEP7 Overload Relay or associated equipment. A hazard
of personal injury and/or equipment damage exists if codes are ignored
during installation.
ATTENTION: The earth ground terminal of the CEP7 Overload Relay shall
be connected to a solid earth ground via a low-impedance connection.

Installation & Wiring
Typical Motor Connections Three-Phase Direct On-Line (DOL) & Single-Phase Full Voltage
ATTENTION: When working on energized circuits, DO NOT rely on
voltage and current information provided by the CEP7-C1 and CEP7 C2/C3/
C5 Overload Relay for personal safety. Always use a portable voltage or
current measurement device to measure the signal locally.
IMPORTANT
Single/Three Ph, Parameter 27, should be set to single-phase.
IMPORTANT
Traditional single-phase wiring connecting T2 to L3 will result in a vector
imbalance of current flowing through the CEP7 C2/C3/C5 Overload Relay.
This will result in inaccurate ground fault reporting and protection.
The following wiring diagram illustrates the CEP7 Overload Relay typical motor
connections in a three-phase DOL and Single-Phase Full Voltage applications.

Cat. No. CEP7-C_-CT-5000 Overload Relays are designed for use with
separately 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 CEP7-C_-CT-5000 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
32
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
Installation & Wiring
Chapter 2
CEP7 Overload Relay power terminals as shown in Figure 13 on page 34. 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 CEP7 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
of ≤±2% over its normal operating range. Typical CT ratings include:
• ANSI USA
• CSA (Canada)
• IEC (Europe)
• Class C5 BO.1
• Class 10L5
• 5 VA Class SP10
ATTENTION: The improper selection of a current transformer can result
in the CEP7 Overload Relay reporting inaccurate motor operational data
and possible motor damage. The selected current transformer must be
rated for protective relaying applications.
Installation Requirements
• Cat. No. CEP7-C_-CT-5000 Overload Relays are designed to be installed
inCEP7-CPM2 Panel Mount Adapters and connected to separately
mounted current transformers.
• For CEP7-CPM2 Panel Mount Adapter assembly, refer to the instructions
included with the panel mount adapter.
ATTENTION: Placing the CEP7 Overload Relay closer than the
recommended distance, six times the cable diameter (including
insulation), may compromise its current reporting and protection
capabilities.
• The CEP7 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 CEP7 Overload Relay.

Core Balanced Ground Fault Sensor Application
Cat. No. CEP7-C3-_ and CEP7-C5- _ overload relays are intended to provide
ground fault protection when used with the Cat. No. CEP7-CBCT_ external
ground fault (core balance) sensor. The ground fault sensor mounts separately
from the CEP7 and must be placed within three meters of the CEP7. The
customer-supplied power cable for wiring the ground fault sensor to the CEP7
Overload Relay must meet the specifications outlined in Table 7 on page 27.
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 CEP7 C3/

the overload relay’s ratings, an interposing relay must be used.
ATTENTION: When the power is applied to the CEP7 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.
ATTENTION: Do not apply external voltage to 1T1, 1T2, or the input

Protective Trip & Warning Functions
Introduction
The purpose of this chapter is to provide detailed information regarding the
protective trip and warning functions of the CEP7 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
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.
IMPORTANT
The CEP7 Overload Relay requires overload trip protection to be enabled
at all times. The CEP7 C2/C3/C5 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
Warning Enable, Parameter 25, allows the installer to enable or disable the desired
warning functions separately. All warning functions are disabled from the factory.
Overload Protection
The CEP7 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 CEP7 Overload Relay will trip with an overload indication if:
• no trip currently exists,
• overload protection is enabled, and
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
45
Chapter 3
Protective Trip & Warning Functions
• % Therm Utilized reaches 100%.
If the CEP7 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).
IMPORTANT
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 CEP7 C2/C3/C5 Overload Relay units for programming the highspeed FLA values in two-speed motor applications. The FLA Setting ranges and
default values for the various CEP7 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. CEP7-C_-CT-5000)
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.

ATTENTION: Improper configuration of the CT Ratio parameter can result
in the CEP7 Overload Relay reporting inaccurate motor operational data
and possible motor damage.
IMPORTANT
Catalog Numbers Cat. Nos. CEP7-C_-180-_ _ _ , CEP7-C_-420-_ _ _ , and
CEP7-C_-860-_ _ _ are assemblies that contain primary current
transformers. The device nameplate identifies the propter CT ratio to be
programmed and the associated legal FLA setting range.
IMPORTANT
The CEP7 Overload Relay’s TRIP/WARN LED status indicator will flash an
amber configuration warning (13-flash sequence) when the FLA setting is
outside of the legal range of the selected CT Ratio setting (e.g., CT Ratio
set at 300:5 and the FLA Setting at 50 A).
Trip Class
Trip Class is defined as the maximum time (in seconds) for an overload trip to
occur when the motor’s operating current is six times its rated current. The CEP7
Overload Relay offers an adjustable trip class range of 5…30, which can be
programmed in increments of one via Trip Class, Parameter 29.
Trip Curves
The following figures illustrate the CEP7 Overload Relay’s time-current
characteristics for trip classes 5, 10, 20, and 30.

Auto/Manual Reset
OL/PTC ResetMode, Parameter 30, allows the user to select the reset mode for
the CEP7 Overload Relay after an overload or thermistor (PTC) trip. If an
overload trip occurs and automatic reset mode is selected, the CEP7 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 CEP7 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 CEP7 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.

Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
Protective Trip & Warning Functions
Chapter 3
Overload Diagnostics
Time to Trip
When the measured motor current exceeds the trip rating of the CEP7 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 CEP7 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.
Non-Volatile Thermal Memory
The CEP7 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
CEP7 Overload Relay checks the thermal memory circuit voltage to determine
the initial value of % Therm Utilized, Parameter 9.
Phase Loss Protection
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 CEP7 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 CEP7-UM002I-EN-P - December 2011
51
Chapter 3
Protective Trip & Warning Functions
• Current Imbal is equal to or greater than 100% for a time period greater
than the programmed PL Trip Delay.
If the CEP7 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).
IMPORTANT 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.
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.
IMPORTANT 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 CEP7
Overload Relay does not begin monitoring for a phase loss condition until
the PL Inhibit Time expires.
Ground Fault Protection
(CEP7 C2/C3/C5)
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 CEP7 C2/C3/C5 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.

ATTENTION: The CEP7 C2/C3/C5 Overload Relay is not a ground fault
circuit interrupt or for personal protection as defined in Article 100 of the
NEC.
ATTENTION: The CEP7 C2/C3/C5 Overload Relay is not intended to
signal a disconnecting means to open the faulted current. A disconnecting
device must be capable of interrupting the maximum available fault
current of the system on which it is used.
Ground Fault Setting Range
Series A and B CEP7 C2/C3/C5 Overload Relays have one ground fault sensing
range, 1…5 A. CEP7 C2/C3/C5 Overload Relays, Series C and later, using an
CEP7-CBCT external core balance ground fault sensor have four sensing ranges
which are selectable via the GF Sensing Range, Parameter 106. These ranges are:
• 20…100 mA — For resistive loads only. For motor load information,
consult your local Sprecher + Schuh sales office.
• 100…500 mA
• 200 mA …1.0 A
• 1.0…5.0 A
Ground Fault Trip
The CEP7 C2/C3/C5 Overload Relay will trip with a ground fault indication if:
• no trip currently exists,
• ground fault protection is enabled,
• GF Inhibit Time has expired, and
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
53
Chapter 3
Protective Trip & Warning Functions
• GF Current is equal to or greater than the GF Trip Level for a time period
greater than the GF Trip Delay.
If the CEP7 C2/C3/C5 Overload Relay trips on a ground fault, the:
• TRIP/WARN LED will flash a red 4-blink pattern,
• bit 3 in Parameter 14, Trip Status, will set to 1,
• bit 0 of Parameter 21, Device Status, will set to 1,
• trip relay contact will open, and
• outputs will be placed in their Protection Fault state (if so programmed).
IMPORTANT

•
•
OUTA Pr FltState, Parameter 65
OUTA Pr FltValue, Parameter 66
OUTB Pr FltState, Parameter 71
OUTB Pr FltValue, Parameter 72
GF Inhibit Time, Parameter 35, allows the installer to inhibit a ground fault trip
from occurring during the motor starting sequence and is adjustable from 0…250
seconds.
GF Trip Delay, Parameter 36, allows the installer to define the time period a
ground fault condition must be present before a trip occurs and is adjustable from
0.0…25.0 seconds.
Parameter 37, GF Trip Level, allows the installer to define the ground fault
current at which the CEP7 C2/C3/C5 Overload Relay will trip and is adjustable
from:
• 1.0…5.0 A (Cat. No. CEP7 C2_ _)
• 20.0 mA…5.0 A (Cat. No. CEP7 C3_ _ and Cat. No. CEP7 C5_ _ )
IMPORTANT
The ground fault inhibit timer starts after the maximum phase load
current transitions from 0 A to 30% of the device’s minimum FLA Setting
or the GF Current is greater than or equal to 50% of the device’s minimum
GF Current Setting. The CEP7 Overload Relay does not begin monitoring
for 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:
54
The GF Trip Inhibit feature is only available in CEP7 C2/C3/C5 Overload Relays
Series B and later.
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
Protective Trip & Warning Functions
Chapter 3
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 CEP7 C2/C3/C5 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.
When the ground fault warning conditions are satisfied, the
• TRIP/WARN LED status indicator will flash an amber 4-blink pattern,
• bit 3 in Warning Status, Parameter 15, will set to 1, and
• bit 1 of Device Status, Parameter 21, will go to 1.
GF Warn Level, Parameter 38, allows the installer to define the ground fault
current at which the CEP7 C2/C3/C5 Overload Relay will indicate a warning
and is 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.
IMPORTANT
In CEP7 C2/C3/C5 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 CEP7 C2/C3/C5 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.
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
55
Chapter 3
Protective Trip & Warning Functions
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 CEP7 Overload Relay will trip with a stall indication when:
• no trip currently exists,
• stall protection is enabled, and
• the maximum phase current is greater than the Stall Trip Level for a time
period greater than the Stall Enabled Time.
If the CEP7 Overload Relay trips on a stall, the:
• TRIP/WARN LED status indicator will flash a red 5-blink pattern,
• bit 4 in Trip Status, Parameter 14, will set to 1,
• bit 0 in Device Status, Parameter 21, will set to 1
• Trip Relay contacts will open, and
• outputs will be placed in their Protection Fault state (if so programmed).
IMPORTANT
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
Stall Enabled Time, Parameter 39, allows the installer to adjust the time the
CEP7 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.
IMPORTANT
56
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 CEP7 Overload Relay
disables Stall Protection until the next motor starting sequence.
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
Protective Trip & Warning Functions
IMPORTANT
Jam Protection (High
Overload)
Chapter 3
The CEP7 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 greater than the motor’s nameplate rating may indicate a high
overload or stall condition, such as an overloaded conveyor or jammed gear.
These conditions can result in overheating of the motor and equipment damage.
Rapid jam fault detection helps to minimize damage and loss of production.
Jam Trip
The CEP7 Overload Relay will trip with a jam indication if:
• no trip currently exists,
• Jam Protection is enabled,
• Jam Inhibit Time has expired, and
• the maximum phase current is greater than the Jam Trip Level for a time
period greater than the Jam Trip Delay.
If the CEP7 Overload Relay trips on a jam, the:
• no trip currently exists,
• Jam Protection is enabled,
• Jam Inhibit Time has expired,
• maximum phase current is greater than the Jam Trip Level for a time period
greater than the Jam Trip Delay.
If the CEP7 Overload Relay trips on a jam, the:
• TRIP/WARN LED status indicator will flash a red 6-blink pattern,
• bit 5 in Trip Status, Parameter 14, will set to 1,
• bit 0 in Device Status, Parameter 21, will set to 1,
• Trip Relay contact will open, and
• outputs will be placed in their Protection Fault State (if so programmed).
IMPORTANT

•
OUTA Pr FltState, Parameter 65
OUTA Pr FltValue, Parameter 66
OUTB Pr FltState, Parameter 71
OUTB Pr FltValue, Parameter 72
Jam Inhibit Time, Parameter 41, allows the installer to inhibit a jam trip from
occurring during the motor starting sequence. It is adjustable from 0…250
seconds.
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
57
Chapter 3
Protective Trip & Warning Functions
Jam Trip Delay, Parameter 42, allows the installer to define the time period a jam
condition must be present before a trip occurs. It is adjustable from 0.1…25.0
seconds.
Jam Trip Level, Parameter 43, allows the installer to define the current at which
the CEP7 Overload Relay will trip on a jam. It is user-adjustable from 50…600%
of the FLA Setting, Parameter 28.
IMPORTANT
The Jam Inhibitor timer starts after the maximum phase of load current
transitions from 0 A to 30% of the device’s minimum FLA setting. The
CEP7 Overload Relay does not begin monitoring for a jam condition until
the Jam Inhibit Time expires.
Jam Warning
The CEP7 Overload Relay will indicate a Jam warning if:
• no warning currently exists,
• Jam Warning is enabled,
• Jam Inhibit Time has expired, and
• the maximum phase current is equal to or greater than the JamWarn Level.
When the Jam Warning conditions are satisfied, the:
• TRIP/WARN LED will flash an amber 6-blink pattern,
• bit 5 in Parameter 15, Warning Status, will set to “1”, and
• bit 1 in Parameter 21, Device Status, will set to “1”.
Jam Warn Level, Parameter 44, allows the installer to define the current at which
the CEP7 Overload Relay will indicate a warning. It is user-adjustable from
50…600% for the FLA Setting, Parameter 28.
IMPORTANT
Underload Protection
The Jam Warning function does not include a time delay feature. Once
the Jam Inhibit Time has expired, the Jam Warning indication is
instantaneous.
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.
Underload Trip
The CEP7 Overload Relay will trip with an underload indication if:

underload condition must be present before a trip occurs. It is adjustable from
0.1…25.0 seconds.
UL Trip Level, Parameter 47, allows the installer to define the current at which
the CEP7 Overload Relay will trip on an Underload. It is user-adjustable from
10…100% ➊ of the FLA Setting, Parameter 28.
➊ 50…100% for devices with firmware revision (FRN) 1.003 and earlier.
IMPORTANT
The Underload Inhibit Timer starts after the maximum phase of load
current transitions from 0 A to 30% of the device’s minimum FLA setting.
The CEP7 Overload Relay does not begin monitoring for an underload
condition until the UL Inhibit Time expires.
IMPORTANT
For any given application, the practical limit of the UL Trip Level,
Parameter 47, will be dependent on the FLA Setting and the lower limit
of the CEP7 Overload Relay’s current measurement capability. See Table
34 on page 142.
Underload Warning

is instantaneous.
Thermistor/PTC Protection
The CEP7 C2 and C3 Overload Relay models 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 transitions from a
low to high value. Since PTC sensors react to actual temperature, enhanced
motor protection can be provided to address such conditions as obstructed
cooling and high ambient temperatures.
The following table defines the CEP7 C2/C3 Overload Relay’s PTC thermistor
input and response ratings.

Parameter 30, OL/PTC ResetMode, allows the user to select the reset mode for
the CEP7 C2/C3 Overload Relay after an overload or thermistor (PTC) trip. If a
PTC trip occurs and automatic reset mode is selected, the relay will automatically
reset when the PTC resistance drops below the reset resistance. If manual reset
mode is selected, the CEP7 C2/C3 Overload Relay must be manually reset after
the PTC resistance drops below the relay’s reset resistance.

Current Imbalance
Protection
A current imbalance can be caused by an unbalance in the voltage supply, unequal
motor winding impedance, or long and varying wire lengths. When a current
imbalance exists, the motor can experience an additional temperature rise,
resulting in degradation of the motor insulation and reduction of life expectancy.
Rapid Current Imbalance fault detection helps extend motor life expectancy and
minimize potential damage and loss of production.
Current Imbalance can be defined by the following equation:
%CI = 100% * (Id/Ia)
where
%CI = Percent Current Imbalance
Id = Maximum Deviation from the Average Current
Ia = Average Current
Current Imbalance Trip
The CEP7 Overload Relay will trip with a Current Imbalance indication if:

Protective Trip & Warning Functions
Preventive Maintenance
Diagnostics (CEP7 Overload
Relays Series C & Later)
Chapter 3
The purpose of this section is to provide detailed information regarding the
Preventive Maintenance Diagnostic functions of the CEP7 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 CEP7 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).
IMPORTANT
The CEP7 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 CEP7 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 CEP7 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 CEP7 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”,
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
91
Chapter 3
Protective Trip & Warning Functions
• Trip Relay contact will be open, and
• outputs will be placed in their Protection Fault state (if so programmed).
IMPORTANT
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 CEP7 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.
IMPORTANT
The CEP7 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 CEP7 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
92
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
Protective Trip & Warning Functions
Chapter 3
• bit 1 in Device Status, Parameter 21, will set to “1”.
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 CEP7 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 CEP7 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 CEP7
programming and control terminal when modifying the CEP7 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 CEP7 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.
Introduction
CEP7 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 CEP7
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.

Choosing the size and format of the I/O data that is exchanged by the CEP7
Overload Relay is done by selecting Input and Output Assembly instance
numbers. Each assembly has a given size (in bytes). This instance number is
written to the Input Assembly and Output Assembly parameters. The different
instances/formats allow for user programming flexibility and network
optimization.
IMPORTANT
The Output Assembly and Input Assembly parameter values cannot be
changed while the CEP7 Overload Relay is online with a scanner. Any
attempts to change the value of this parameter while online with a
scanner will result in the error message “Object State Conflict”.

Programmable Parameters
Introduction
This chapter describes each programmable parameter and its function.
Programming
Refer to Chapter 4 for instructions in using RS NetWorx for DeviceNet to
modify parameter settings and Input and Output Assemblies.
IMPORTANT
Parameter setting changes downloaded to the CEP7 Overload Relay take
effect immediately, even during a “running” status.
IMPORTANT
Parameter setting changes made in a configuration tool, (e.g.,
RSNetWorx for DeviceNet) do not take effect in the CEP7 Overload Relay
until the installer applies or downloads the new settings to the device.
Program Lock
Program Lock, Parameter 53, provides a degree of security from having parameter
settings unintentionally altered when programmed to the “locked” setting.
Reset to Default Factory Settings
Set to Defaults, Parameter 54, allows the installer to reset all parameter settings
(including trip logs) to the factory default values.
IMPORTANT
Parameter Group Listing
Resetting to factory default values also resets the CEP7 Overload Relay’s
DeviceNet node address (MAC ID) to the default value of 63.
The CEP7 Overload Relay can contain up to 13 parameter groups, depending on
the model number and firmware revision. In this chapter, the following parameter

Output Setup Group
IMPORTANT
The parameters in the Output Setup Group provide great flexibility in
terms of output relay(s) operation under the conditions of Protection
Faults, Comm Fault, and Comm Idle. It is important, therefore, that the
installer fully understands the use of these parameters, their interaction
with Trip Enable, Parameter 24, and the order of priority.
Order of Priority
The Out_Pr FltState parameter settings take priority over the other
settings.
If Comm Fault and Comm Idle are enabled (set to 1) in Trip Enable, the
state that the output(s) assumes is first determined by the settings in the
Out_Pr FltState and Out_PrFltValue parameters.
If Out_Pr FltState is set to 1 = ignore fault, the state of the output(s) will
be determined by the Out_DN FltState and Out_DN FltValue, and
Out_DN IdlState and Out_DN IdlValue settings.
If Comm Fault and Comm Idle are disabled (set to 0) in Trip Enable, the
state that the output(s) assumes will be determined by the Out_DN
FltState and Out_DN Flt Value, and Out_DN IdlState and Out_DN
IdleValue settings.
IMPORTANT
The following information addresses the behavior variation between
Series A and Series B and later products in relation to the Output Setup
parameters.
CEP7 is Normal – No Trip Present
In normal operation, the CEP7 Overload Relay firmware latches Out A and Out
B commands received through Polled I/O and Explicit messaging. The latched
states are applied to the outputs until the next command is received.
Rockwell Automation Publication CEP7-UM002I-EN-P - December 2011
127
Chapter 5
Programmable Parameters
CEP7 is Tripped
In the event of a protection trip, the state of an CEP7 Overload Relay output is
determined by the programmed settings of the corresponding Out_ Pr FltState
and Out_ Pr FltValue parameters.
When Out_ Pr FltState is set to “Ignore Fault”, output operation continues to
respond to message commands. When Out_ Pr FltState is set to “Go to FltValue”,
the output commanded states are determined by the settings of the Out_ Pr
FltValue parameters, regardless of the state of the firmware latch.
Series A product continues to update the firmware latch as new commands are
received while the CEP7 Overload Relay is in a tripped state.
Series B and later product sets the firmware latch to the Out_ Pr FltValue when
Out_ Pr FltState is set to “Go to FltValue” while the CEP7 Overload Relay is in a
tripped state.
CEP7 is Reset from Trip
After an CEP7 Overload Relay is returned to normal following a trip reset,
operation of Out A and Out B is determined by the state of the firmware latch.
The output state matrix below details this.

Monitoring Parameters
Introduction
This chapter provides information for the current monitoring and diagnostic
parameters of the CEP7 Overload Relay.
Phase Current Reporting
Current Range
The CEP7 Overload Relay utilizes a true RMS algorithm to calculate the RMS
value of the current passing through phase L1, L2, and L3. The relay is capable of
sensing currents ranging from 0%…720% of the maximum FLA Setting.
IMPORTANT The CEP7 Overload Relay will report 0 A or 0% FLA if the
current is below 30% of the minimum FLA Setting.
IMPORTANT The CEP7 Overload Relay is capable of reporting values
greater than 720% of the maximum FLA Setting, but the
accuracy of the value may be compromised.
The following chart illustrates the reporting current precision, the minimum and
maximum reporting current values, and the 720% maximum FLA value for each
current range.

Voltage Parameters
Introduction
The CEP7-C5 has the capability to protect against poor voltage quality by
offering voltage based protection. The user can prevent a contactor from
energizing if the voltage is either too high or too low. This model also provides
maintenance personnel with voltage based diagnostic information when
investigating an unplanned shut down. This chapter provides information for the
voltage monitoring and setup parameters for the CEP7-C5 Overload Relay.
Phase Voltage Reporting
Voltage Range
The CEP7-C5 utilizes a true RMS algorithm to calculate the RMS value of the
voltage that exists on L1, L2, and L3. The relay is capable of sensing voltages
ranging from 0V L-L to 690V L-L for frequencies ranging from 20 Hz to 250 Hz.
The relay supports the following voltage systems:
• Single Phase (2 Wire)
• Delta (Direct Connection)
• Wye (Direct Connection or with 3 Potential Transformers)
• Open Delta (with 2 Potential Transformers)
• Delta with PT (with 3 Potential Transformers)
IMPORTANT
The CEP7-C5 will report 0 V if the voltage is below 50V L-L .
IMPORTANT
The CEP7-C5 is capable of reporting values greater than 690V
L-L and for frequencies less than 40 Hz or greater than 80 Hz,
but the accuracy of the value may be compromised.
IMPORTANT
The CEP7-C5 calculates frequency based on the voltage signal
on L1.
The following chart illustrates the reported voltage parameters based on the
chosen voltage mode. Parameters that do not have an "X" will report 0.

Power Parameters
Introduction
The CEP7-C5 offers power based motor protection. This model also provides
maintenance personnel with power based diagnostic information when
investigating an unplanned shut down or performing energy management. This
chapter provides information for the power monitoring and setup parameters for
the CEP7-C5 Overload Relay.
Phase Power Reporting
Power Range
The CEP7-C5 provides power based diagnostic information that includes real
power (kW), reactive power (kVAR), apparent power (kVA), and power factor
(PF). The relay also provides energy based diagnostic information that includes
kWh, kVARh, kVAh, kW Demand, kVAR Demand, and kVA Demand. The relay
is capable of sensing power and energy ranging from 0V L-L to 690V L-L for
frequencies ranging from 20 Hz to 250 Hz. The relay supports the following
voltage systems:
• Single Phase (2 Wire)
• Delta (Direct Connection)
• Wye (Direct Connection)
• Open Delta (with 2 Potential Transformers)
• Delta with PT (with 3 Potential Transformers)
The CEP7-C5 is intended to be used in applications that represent quadrants I
and IV of the power circle shown in Explanation of Power Parameter Signs

IMPORTANT
The CEP7-C5 will report 0 for all power based parameters if the
voltage is below 50V L-L .
IMPORTANT
The CEP7-C5 is capable of reporting power values when the
voltage is greater than 690V L-L and for frequencies less than
40 Hz or greater than 80 Hz; however, the accuracy of the
value may be compromised.
The following chart illustrates the reported power parameters based on the
chosen voltage mode. Parameters that do not have an "X" will report 0.

Logic Controller Communication Examples
Introduction
The CEP7 Overload Relay communicates its diagnostic information through a
DeviceNet network using I/O Messaging or Explicit Messaging. The CEP7
Overload Relay will control its output relays via a DeviceNet network through
the use of I/O Messaging. This chapter will show an example of I/O Messaging
and four examples of Explicit Messaging including the Parameter Object, the
Control Supervisory Object, the Overload Object, and the CEP7 Status Object.
The examples will use a CompactLogix L32E via a 1769-SDN DeviceNet
scanner module named DNET. The applications shown are example-specific.
Some changes by the user may be necessary to apply the concepts of these
examples to a specific application.
Figure 2: Network Example
I/O Messaging
For this example, a CompactLogix L32E will energize OUT A on a CEP7 C3

To have the CompactLogix controller energize OUT A of the CEP7 C3
Overload Relay using I/O Messaging, set Bit 0 in Word 1:O.Data[0] to a 1.
OUT A should be energized.
To verify that OUT A of the CEP7 C3 Overload Relay was energized, the
CompactLogix controller will read the device status of the CEP7 C3 Overload
Relay and place that information at Word 1:I.Data[0] with the L32E. Bit 2
identifies the state of OUT A.

Explicit Messaging
The CEP7 Overload Relay supports Explicit Messaging via DeviceNet. This
allows a controller to read and write various parameters from an CEP7 Overload
Relay using the unused bandwidth of the DeviceNet network. In these examples,
a CompactLogix L32E controller will read a parameter or group of parameters
from the CEP7 C3 located on Node 6 on a DeviceNet network using the
following DeviceNet objects:
• Parameter Object (0x0F)
• Control Supervisor Object (0x29)
• Overload Object (0x2C)
• CEP7 Status Object (0x0375)
Reading Device Status using the Parameter Object Class (0x0F)
In this example a Periodic Task has been configured within the L32E to execute
every 1000 ms in which a message instruction will be used to read the Device
Status of the CEP7 C3 Overload Relay using the Parameter Object Class. The
supporting ladder logic was added to execute a MSG instruction every time this
Periodic Task executes.
The Device Status is located in Parameter 21 within the CEP7 C3 Overload
Relay. Setup the MSG instruction in the Configuration tab to read Parameter 21
using the Parameter Object Class by configuring the following fields:

Using DeviceLogix™
Introduction
DeviceLogix is a stand-alone Boolean program which resides within the CEP7
C2/C3/C5 Overload Relay. RS NetWorx for DeviceNet is required to program
the device; however, since the program is embedded in the CEP7 C2/C3/C5
software, no additional module is required to use this technology. It is important
to note that the DeviceLogix program will only run if the logic has been enabled,
which can be done within the Logic Editor of RSNetWorx for DeviceNet or the
DeviceNet Configuration Terminal (Cat. No. CEP7-DNCT).
In addition to executing specific Boolean logic, DeviceLogix can also be used to
provide specific output performance under specific communication or network
conditions. This can be accomplished by properly configuring Comm Override
and Network Override parameters.
Comm Override. The configuration of the Comm Override parameter
defines whether or not DeviceLogix controls the CEP7 C2/C3/C5
outputs when either a Comm Fault (lack of I/O connection) or Comm
Idle (Master not in Run mode) condition exists. If DeviceLogix is enabled
but Comm Override is disabled (default), the operation of the CEP7
C2/C3/C5 outputs will be controlled by the DeviceNet Fault State, Fault
Value, Idle State, and Idle Value parameters if a Comm Fault or Comm Idle
condition occurs. If DeviceLogix and Comm Override are both enabled,
the CEP7 C2/C3/C5 outputs are controlled by the DeviceLogix program,
regardless of the Comm Fault or Comm Idle state. If DeviceLogix is not
enabled, the outputs will be controlled by the DeviceNet Fault/Idle
State/Value parameters if a Comm Fault or Comm Idle condition occurs –
regardless of the Comm Override configuration. If DeviceLogix is
transitioned from enable to disable, the outputs will immediately go to the
programmed DeviceNet Idle State/Value.
Network Override. The configuration of the Network Override
parameter defines whether or not DeviceLogix controls the CEP7
C2/C3/C5 outputs when a network fault, such as a duplicate Mac ID or
bus off condition, exists. If DeviceLogix is enabled but Network Override is
disabled (default), the operation of the CEP7 C2/C3/C5 outputs will be
controlled by the DeviceNet Fault State and Fault Value parameters if a
network fault occurs. If DeviceLogix and Network Override are both
enabled, the CEP7 C2/C3/C5 outputs are controlled by the DeviceLogix
program, regardless of the network status. If DeviceLogix is not enabled,
the outputs will be controlled by the DeviceNet Fault/Idle State/Value
parameters if a Comm Fault condition occurs – regardless of the Network
Override configuration. If DeviceLogix is transitioned from enable to
disable, the outputs will immediately go to the programmed DeviceNet
Idle State/Value.

Using DeviceLogix™
DeviceLogix Programming
DeviceLogix has many applications and the implementation is typically only
limited to the imagination of the programmer. Keep in mind that the application
of DeviceLogix is only designed to handle simple logic routines.
DeviceLogix is programmed using simple Boolean math operators, such as AND,
OR, NOT, timers, counters, and latches. Decision making is made by combining
these Boolean operations with any of the available I/O. The inputs and outputs
used to interface with the logic can come from the network or from the device
hardware. Hardware I/O is the physical Inputs and Outputs located on the device
such as push buttons and pilot lights that are connected to the CEP7 C2/C3/C5
Overload Relay. There are many reasons to use the DeviceLogix functionality,
but some of the most common are listed below:
• Increased system reliability
• Improved diagnostics and reduced troubleshooting
• Operation independent of PLC or Network status
• Continue to run process in the event of network interruptions
• Critical operations can be safely shutdown through local logic
DeviceLogix can be programmed using function blocks or ladder logic through
RS NetWorx for DeviceNet. After a successful download to the CEP7
C2/C3/C5 overload relay, DeviceLogix can be enabled using RS NetWorx for
DeviceNet or the DeviceNet configuration terminal (Cat. No. CEP7-DNCT).
DeviceLogix Programming Example
The following example shows how to program a simple logic routine to control
the CEP7 C2/C3/C5 Overload Relay’s outputs based on the condition of input
signals. OUT A control is defined by the states of IN1 and IN2 processed
through a Boolean OR gate. OUT B control is defined by the states of IN3 and
IN4 processed through a separate Boolean OR gate. This example is using
RS NetWorx for DeviceNet version 8.00.01 and an CEP7 C3 Series C overload
relay.
IMPORTANT Before programming logic it is important to decide on the
conditions under which the logic run. As defined earlier, the
conditions can be defined by setting parameter 79 (Comm
Override) and parameter 80 (Network Override) to the value
that you want.

Troubleshooting
Introduction
The purpose of this chapter is to assist in troubleshooting the CEP7 Overload
Relay using its advisory LEDs and diagnostic parameters.
ATTENTION: Servicing energized industrial control
equipment can be hazardous. Electrical shock, burns, or
unintentional actuation of controlled industrial
equipment may cause death or serious injury. For safety
of maintenance personnel as well as others who may be
exposed to electrical hazards associated with the
maintenance activities, follow the local safety-related
work practices (for example, the NFPA 70E, Part II,
Electrical Safety for Employee Workplaces, in the United
States) when working on or near energized equipment.
Maintenance personnel must be trained in the safety
practices, procedures, and requirements that pertain to
their respective job assignments. Do not work alone on
energized equipment.
ATTENTION: Do not attempt to defeat or override fault
circuits. The cause of a fault indication must be
determined and corrected before attempting operation.
Failure to correct a control system or mechanical
malfunction may result in personal injury and/or
equipment damage due to uncontrolled machine
system operation.

IMPORTANT Cycling power to the CEP7 Overload Relay will not clear a
“Non-Volatile Fault”. A “Non-Volatile Fault” must be manually
reset. An Overload or PTC Fault can also be automatically
reset.
Network Status LED
This LED provides information on the state of the CEP7 Overload Relay’s
DeviceNet network connection. Refer to the DeviceNet Troubleshooting
Procedure section for descriptions of the various states this LED can take and the
associated recommended corrective action.
OUT A & OUT B LEDs
The amber OUT A or OUT B LED illuminates when the output is commanded
on. However, an illuminated LED does not guarantee that the output is actually
on.
IN 1,2,3 & 4 LEDs
The amber IN1, IN2, IN3, or IN4 LED illuminates when a user-connected
contact is closed.
Power-Up Sequence
After the CEP7 Overload Relay is installed according to the guidelines specified
in Chapter 2, apply power to the overload relay’s DeviceNet connector. After
applying power, the following sequence should occur:
1. The Trip relay should close 2.35 seconds later and the TRIP/WARN LED
will not flash (unless a “Non-Volatile Fault” previously existed or a fault
condition is present).
2. At the same time, the NETWORK STATUS LED should flash green for
approximately 2 seconds, then red for 1/4 second. If autobaud is enabled
and the CEP7 Overload Relay is connected to an active network, the green
LED will continue to flash once the baud rate has been determined. If the
CEP7 Overload Relay is not connected to an active network, this LED will
not continue to flash.
3. Once the CEP7 Overload Relay has been allocated by a Master, the
NETWORK STATUS LED will turn solid green.

Chapter 12
Troubleshooting
DeviceNet Modes of
Operation
The CEP7 Overload Relay has four DeviceNet modes of operation: Power-up
Reset Mode, Run Mode, Recoverable Error Mode, and Unrecoverable Error
Mode.
Power-Up Reset Mode
During Power-Up Reset Mode, the following occurs:
1. The NETWORK STATUS LED should flash green for approximately 2
seconds, then red for 1/4 second. If autobaud is enabled and the CEP7
Overload Relay is connected to an active network, the green LED will
continue to flash once the baud rate has been determined. If the CEP7
Overload Relay is not connected to an active network, this LED will not
continue to flash.
IMPORTANT The CEP7 Overload Relay protection functions are still
operational even without an established network
connection.
2. Once the baud rate is determined, the CEP7 Overload Relay performs a
duplicate node address check to verify another node is not assigned to the
same DeviceNet node address (MAC ID). If a duplicate node is detected
on the network, the NETWORK STATUS LED turns solid red, and the
CEP7 Overload Relay enters the Recoverable Error Mode.
If the power-up or reset is successful, the overload relay will enter Run Mode.
Run Mode
In Run Mode, the CEP7 Overload Relay will operate as a slave device to a master
device. The NETWORK STATUS LED will blink green if there are no network
connections established with a network master. When one or more connections
are in the “established” state, the NETWORK STATUS LED will turn solid
green. When one or more connections are in the “timed-out” state, the
NETWORK STATUS LED will blink red. In the Run Mode, the CEP7
Overload Relay will:
1. Accept messages from a master on the DeviceNet network
2. Send response messages, COS messages, or CYCLIC messages to a master.
If a communication error is detected, the CEP7 Overload Relay will either enter
the Recoverable Error or Unrecoverable Error Mode.

Resetting a Trip
ATTENTION: Resetting a trip will not correct the cause
for the trip. Corrective action should be taken before
resetting the trip.
An CEP7 Overload Relay trip condition can be reset by taking one of the
following actions:
1. Actuating the TRIP/RESET button on the CEP7 Overload Relay.
2. Setting the Fault Reset bit in the CEP7 Overload Relay’s Output Assembly
via the DeviceNet network.
3. Actuating a reset signal
4. Actuating a reset signal to IN1 when Parameter 77, IN1=Trip Reset, in
enabled (Series A, FRN 2.xxx).
5. Actuating a reset signal to one of the inputs when programmed to “Trip
Reset” via one of the corresponding assignment parameters (83…86) (FRN
3.xx and later)

DeviceNet™ Information
Electronic Data Sheets
(EDS)
EDS files are specially formatted ASCII files that provide all of the information
necessary for a configuration tool (e.g., RSNetWorx™ for DeviceNet) to access
and alter the parameters of a device. The EDS file contains all the parameter
information of a device to include:
• number of parameters
• groupings
• parameter name
• minimum, maximum, and default values,
• minimum, maximum, and default units,
• data format, and
• scaling.
EDS files for all CEP7 Overload Relay units are available at
www.rockwellautomation.com/resources/eds. The EDS files may also be built
automatically by some configuration tools since all of the information necessary
for an EDS file may be extracted from the CEP7 Overload Relay.
IMPORTANT
Product Codes
DeviceLogix capability is not available when uploading the EDS from an
CEP7 C2/C3/C5 Overload Relay. The EDS file must be obtained from the
internet.
Since the CEP7 Overload Relay is available in a variety of current ranges, each
model supports a parameter set that is slightly different in terms of min, max, and
default values for parameters that are related to motor current. Therefore, each
model uses an EDS file specific to that model. Configuration tools use “product
codes” to identify which EDS file to use for a given device. The following table
summarizes the various product codes.

CE Compliance
The CEP7 Overload Relay is intended for use in a heavy industrial environment.
It is CE marked for conformity to the Low Voltage Directive 73/23/EEC (as
amended by 93/68/EEC) and the EMC Directive 89/336/EEC (as amended by
92/31/EEC and 93/68/EEC) when installed as described in this manual.
IMPORTANT
The conformity of the CEP7 Overload Relay to these standards does not
guarantee that an entire installation will conform. Many other factors
can influence the entire installation and only direct measurements can
verify total system conformity. It is therefore the responsibility if the
installer to ensure system conformity.

Two-Speed Applications
Introduction
The CEP7 C2/C3/C5 Overload Relay Series B and later provides 2-Speed FLA
Set, Parameter 88, for use in two-speed motor applications. This appendix
provides overview and guidance on various methods that can be employed to
protect two-speed motors.
External Control
Applications
For applications in which the two-speed starter control is accomplished
externally from the CEP7 C2/C3/C5 outputs, an auxiliary contact associated
with the high speed contactor is wired to one of the CEP7 C2/C3/C5 inputs.
The corresponding input assignment Parameter 83…86 is set to “2-Speed”. The
overload function’s thermal capacity utilized (TCU) calculation is based on the
Parameter 88 setting when the two-speed assigned input is asserted.
Output Control Applications
For applications that use the integral outputs of the CEP7 C2/C3/C5, Out A is
used to control the low speed contactor and Out B is used to control the high
speed contactor. Control can be accomplished through commands transmitted
by the network master or internal DeviceLogix function blocks. When 2-Spd Net
Enable, Parameter 87, is set to “1” or “Enable”, the overload function’s TCU
calculation is based on the 2-Speed FLA Set, Parameter 88, setting when Out B is
commanded closed.
