When the EC4 Current Monitoring Relay is in the unpowered state, the trip relay
contact is open. The trip relay contact closes approximately 2.35 seconds after
power is applied if no trip condition exists.
In addition to the trip relay, the EC4 Current Monitoring Relay provides 4 inputs
and 2 outputs. the inputs are rated 24V DC only. For 120V AC inputs, add the
AC input interface module, Cat. No. 193-EIMD
The status of each can be monitored over the DeviceNet network through
parameter 21, Device Status, or one of the input assemblies. Additionally, the
outputs can be controlled over the network by using one of the output assemblies.
Refer to Appendix B — DeviceNet Information for listings of the available input
and output assemblies.
The EC4 Current Monitoring Relay offers added flexibility by providing the
capability to perform control functions with the inputs and outputs through
DeviceLogix.
The EC4 Current Monitoring Relay inputs are independently configurable for
Trip Reset, Remote Trip, L1 Loss Arm, L2 Loss Arm, L3 Loss Arm, L1L2 Loss
Arm, L2L3 Loss Arm, L1L3 Loss Arm, L1L2L3 Loss Arm, 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 them, and that the explicit
message connection has a non-zero expected packet rate (EPR)
setting.

dependent on the OUTA or OUTB Pr FltState, Pr FltValue, Dn
FltState, Dn FltValue, Dn IdlState, and Dn IdlValue
programmable parameters. For details refer to the Output Setup
Group section of Chapter 5 – Programmable Parameters.
ATTENTION: The EC4 Current Monitoring 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 EC4 Current Monitoring Relay’s Output
Setup group, allow 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. EC4 outputs
that were closed prior to a trip will re-close upon trip
reset, provided that a network “open” command is not
received first.
Status Indication
The EC4 Current Monitoring Relay provides the following LED indicators:
NETWORK STATUS: This green/red LED indicates the status of the network
connection. See Chapter 11 — Troubleshooting for the possible LED
indications and the associated definitions.
TRIP / WARN: This red/amber LED flashes an amber code under a warning
condition and a red code when tripped. The warning or trip code is indicated by
the number of flashes in sequence. Refer to the side label on the product for
trip/warning codes or Chapter 11 — Troubleshooting.

Parameter 27, Single/Three Ph, 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 EC4 Current Monitoring
Relay. This will result in inaccurate ground fault reporting and protection.
EC4 Current Monitoring 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. Parameter 78, CT Ratio, is provided for
setting the current transformer ratio to be installed.
Current Transformer Specifications
The 193-EC_ZZ current monitoring relays are intended for use with CTs with a
secondary current rating of 5 A. The installer shall provide one CT for each
motor phase and shall connect the CT’s secondary leads to the appropriate EC4
Current Monitoring Relay power terminals as shown in . The CTs shall have an
appropriate ratio rating as detailed in Table 3.1. Additionally, the CT shall be
selected to be capable of providing the required VA to the secondary load, which
includes the EC4 Current Monitoring Relay burden of 0.1 VA at the rated

secondary current and the wiring burden. Finally, the CT shall be rated for
protective relaying to accommodate the high inrush currents associated with
motor startup and shall have an accuracy of
≤±2% over its normal operating
range. Typical CT ratings include:
ANSI (USA)Class C5 B0.1
CSA (Canada)Class 10L5
IEC (Europe)5 VA Class 5P10
ATTENTION: The improper selection of a current transformer can
result in the EC4 Current Monitoring Relay reporting inaccurate
motor operational data, and possible motor damage. The selected
current transformer must be rated for protective relaying
applications.
Installation Instructions
Cat. No. 193-EC_ZZ current monitoring relays are designed to be installed in
cat. no. 193-ECPM2 panel mount adapters and connected to separately mounted
current transformers. For panel mount adapter assembly, refer to the instructions
included with the panel mount adapter.The EC4 Current Monitoring 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 EC4 Current Monitoring Relay.
ATTENTION: Placement of the EC4 Current Monitoring Relay
closer than the recommended distance of six times the cable
diameter may compromise its current reporting and protection
capabilities.

EC4 Current Monitoring Relays are intended to provide ground fault protection
when used with the Cat. No. 193-CBCT_ external ground fault (core balance)
sensor. The ground fault sensor mounts separately from the EC4 current
monotoring relay and must be placed within three meters of it. The
customer-supplied cable for wiring the ground fault sensor to the EC4 should
meet the specifications outlined in Table 5.
Power Cable Installation Instructions
1. 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.
2. 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.
3. 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.
4. The power cables of the branch circuit to be protected by the EC4 Current
Monitoring Relay must not be grounded on the load side of the ground
fault sensor.
5. 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.

Introduction
Trip Enable
The purpose of this chapter is to provide detailed information regarding the
protective trip and warning functions of the EC4 Current Monitoring 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.
Parameter 24, Tri p E nable, allows the installer to enable or disable the desired
protective functions separately. The overcurrent, undercurrent, and
communication fault trip functions are enabled from the factory.
The EC4 Current Monitoring Relay requires undercurrent
(UC)/overcurrent (OC) to be enabled at all times. The EC4 Current
Monitoring Relay requires either UC/OC to be enabled at all times.
ATTENTION: The Trip Enable settings should not be altered during
machine operation, as unexpected behavior of the outputs could
occur. This may result in an unintended actuation of controlled
industrial equipment, with the potential for machine damage or
serious injury to personnel.
Warning Enable
Overcurrent Protection
Rockwell Automation Publication 193-UM011A-EN-P - September 201036
Parameter 25, Wa r ni n g E n a bl e , allows the installer to enable or disable the desired
warning functions separately. All warning functions are disabled from the factory.
The EC4 Current Monitoring Relay provides UC/OC protection through true
RMS current measurement of the individual phase currents of the connected
loads. For Undercurrent & Overcurrent Trip and Warning Level parameters, a
warning or trip will occur when the programmed conditions are satisfied.
The EC4 Current Monitoring Relay will issue a warning with an overcurrent
condition if:
• The current in any of the phases exceeds the current specified for the
corresponding OC Warn Level parameter (Parameter 120 for L1,
parameter 123 for L2, & parameter 126 for L3)
• No warning condition already exists
If an overcurrent warning parameter is satisfied, the following will occur:
• The TRIP/WARN LED will flash a yellow blinking pattern depending on
which phase encountered the overcurrent warning condition
– 5 blinks for L1 overcurrent
– 6 blinks for L2 overcurrent
– 7 blinks for L3 overcurrent
• Parameter 15, Warning Status, will change
– Bit 4 will go to "1" for L1 overcurrent
– Bit 5 will go to "1" for L2 overcurrent
– Bit 6 will go to "1" for L3 overcurrent
• Bit _ in Parameter 21, Device Status, will go to "1"
Overcurrent Trip
The EC4 Current Monitoring Relay will trip with an overcurrent indication if:
• The current in any of the phases exceeds the current specified for the
corresponding OC Trip Level parameter (Parameter 118 for L1, parameter
121 for L2, & parameter 124 for L3)
• No trip currently exists
If the EC4 Current Monitoring Relay trips on an overcurrent condition, the
following will occur:
Rockwell Automation Publication 193-UM011A-EN-P - September 201037
Chapter 3 Protective Trip and Warning Functions
• The TRIP/WARN LED will flash a red blinking pattern depending on
which phase encountered the overcurrent
– 5 red blinks for L1 overcurrent
– 6 red blinks for L2 overcurrent
– 7 red blinks for L3 overcurrent
• Parameter 14, Trip Status, will change
– Bit 4 will go to "1" for L1 overcurrent
– Bit 5 will go to "1" for L2 overcurrent
– Bit 6 will go to "1" for L3 overcurrent
• Bit 0 in Parameter 21, Device Status, will go to "1"
• The outputs will be placed in their Protection Fault state (if so
programmed)
Ground Fault Protection
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 EC4 Current Monitoring 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. The EC4 can measure from
20 mA…5 A of ground fault current
➊ Must use one of the followign ground fault sensors:
Cat. No. 193-CBCT1 — 20 mm diameer window
Cat. No. 193-CBCT2 — 40 mm diameer window
Cat. No. 193-CBCT3 — 65 mm diameer window
Cat. No. 193-CBCT4 — 85 mm diameer window
➋ 20…100 mA for resistive loads only. For motor load information, please consult your local Allen-Bradley
distributor.
ATTENTION: The EC4 Current Monitoring Relay is not a ground
fault circuit interruptor for personnel protection as defined in
Article 100 of the NEC.
➊➋.
ATTENTION: The EC4 Current Monitoring 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
EC4 Current Monitoring Relays using the external ground fault sensor (Cat. no.
193-CBCT_) have four sensing ranges, which are selectable via the GF Sensing Range parameter.
Parameter 106, GF Sensing Range (Series C and later)
• 20…100 mA (For resistive loads only. For motor load information, please
consult your local Rockwell Automation sales office or Allen-Bradley
distributor.)
• 100…500 mA
• 200 mA …1.0 A
• 1.0…5.0 A
Ground Fault Trip
The EC4 Current Monitoring Relay will trip with a ground fault indication if:
• No trip currently exists
• Ground fault protection is enabled
• GF Inhibit Time has expired
• GF Current is equal to or greater than the GF Trip Level for a time period
greater than the GF Trip Delay
If the EC4 Current Monitoring Relay trips on a ground fault, the following will
occur:
• The TRIP/WARN LED will flash a red 4-blink pattern
• Bit 3 in Parameter 14, Trip Stat us , will go to “1”
• Bit 0 of Parameter 21, Device Status, will go to “1”
• The Trip Relay contact will open
• 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 Parameter
65 (OUTA Pr FltState), Parameter 66 (OUTA Pr FltValue), Parameter 71
(OUTB Pr FltState), and Parameter 72 (OUTB Pr FltValue).
Parameter 35, GF Inhibit Time, allows the installer to inhibit a ground fault trip
from occurring during the motor starting sequence and is adjustable from 0…250
seconds.
Parameter 36, GF Trip Delay, allows the installer to define the time period a
ground fault condition must be present before a trip occurs. It is adjustable from
0.0…25.0 seconds.
Rockwell Automation Publication 193-UM011A-EN-P - September 201039
Chapter 3 Protective Trip and Warning Functions
IMPORTANT
Parameter 37, GF Trip Level, allows the installer to define the ground fault
current at which the EC4 Current Monitoring Relay will trip. It is adjustable
from 20.0 mA…5.0 A
The ground fault inhibit timer starts after the maximum phase of 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 EC4 Current Monitoring 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.
When enabled, Parameter 89, GF Trip Inhibit, inhibits a ground fault trip from
occurring when the ground fault current exceeds the maximum range of the core
balance sensor (approximately 10 A). Note: This feature is only available in series
B and later devices.
Ground Fault Warning
The EC4 Current Monitoring Relay will indicate a Ground Fault warning if:
• No warning currently exists
• Ground fault warning is enabled
• GF Inhibit Time has expired
• 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 following will
occur:
• The TRIP/WARN LED will flash an amber 4-blink pattern
• Bit 3 in Parameter 15, War n in g S ta t us , will go to “1”
• Bit 1 of Parameter 21, Device Status, will go to “1”
Parameter 38, GF Warn Level, allows the installer to define the ground fault
current at which the EC4 Current Monitoring Relay will indicate a warning and
is adjustable from 20 mA…5.0 A.
Parameter 105, GF Warn Delay (Series C and later), 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.
40Rockwell Automation Publication 193-UM011A-EN-P - September 2010
Protective Trip and Warning Functions Chapter 3
IMPORTANT
In EC4 Current monitoring relays, 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.
Undercurrent Protection
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 undercurrent fault detection helps to minimize damage and
loss of production.
The EC4 Current Monitoring Relay will issue a warning with an undercurrent
condition if:
• The current in an of the phases is lower than the current specified for the
corresponding UC Trip Level parameter (Parameter 110 for L1, parameter
113 for L2, & parameter 116 for L3)
• No warning condition already exists
If an undercurrent warning parameter is satisfied, the following will occur:
• The TRIP/WARN LED will flash a yellow blinking pattern depending on
which phase encountered the undercurrent warning condition
– 2 blinks for L1 undercurrent
– 3 blinks for L2 undercurrent
– 4 blinks for L3 undercurrent
• Parameter 15, War n in g St a tu s , will change
– Bit 1 will go to "1" for L1 undercurrent
– Bit 2 will go to "1" for L2 undercurrent
– Bit 3 will go to "1" for L3 undercurrent
• Bit 1 in Parameter 21, Device Status, will go to "1"

Parameter 48, UL Warn Level, allows the installer to define the current at which
the EC4 Current Monitoring Relay will indicate a warning.
The Underload Warning function does not include a time delay feature.
Once the UL Inhibit Time has expired, the Underload warning indication
is instantaneous.
For any given application, the practical limit of UL Warn Level (Parameter
48) will be dependent upon the FLA setting and the lower limit of the EC4
Current Monitoring Relay’s current measurement capability. See Table 20

Undercurrent Trip
The EC4 Current Monitoring Relay will trip with an undercurrent indication if:
• The current in any of the phases is lower than the current specified for the
corresponding UC Trip Level parameter (Parameter 108 for L1, parameter
111 for L2, & parameter 114 for L3)
• No trip currently exists
If the EC4 Current Monitoring Relay trips on an undercurrent condition, the
following will occur:
• The TRIP/WARN LED will flash a red blinking pattern depending on
which phase encountered the undercurrent condition
– 2 blinks for L1 undercurrent
– 3 blinks for L2 undercurrent
– 4 blinks for L3 undercurrent
• Parameter 14, Tri p S tat us , will change
– Bit 1 will go to "1" for L1 undercurrent
– Bit 2 will go to "1" for L2 undercurrent
– Bit 3 will go to "1" for L3 undercurrent
• Bit 0 in Parameter 21, Device Status, will go to "1"
• 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 Parameter
65 (OUTA Pr FltState), Parameter 66 (OUTA Pr FltValue), Parameter 71
(OUTB Pr FltState), and Parameter 72 (OUTB Pr Flt Value).
Parameter 45, UL Inhibit Time, allows the installer to inhibit an underload trip
from occurring during the motor starting sequence and is adjustable from 0…250
seconds.

Parameter 47, UL Trip Level, allows the installer to define the current at which
the EC4 Current Monitoring Relay will trip on an Underload.
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 EC4 Current Monitoring Relay does not begin monitoring for an
underload condition until the UL Inhibit Time expires.
For any given application, the practical limit of ULTrip Level (Parameter
47) will be dependent on the FLA setting and the lower limit of the EC4
Current Monitoring Relay’s current measurement capability. See Table 20

Communication Fault
Protection
A disruption of the communication link between the EC4 Current Monitoring
Relay and a DeviceNet network can result in the loss of application control
and/or critical process diagnostic data. Rapid communication fault detection
helps minimize potential damage due to uncontrolled or unmonitored
applications.
Comm Fault Trip

Communication Idle
Protection
If a communication fault occurs and either Comm Fault Trip is not enabled or
the Pr FltState parameters are set to “Ignore”, the following will occur:
• The Network Status LED will blink red or become solid red
• The outputs will be placed in their Comm Fault
When a programmable controller is placed into the program mode, the execution
of its ladder program is suspended, and any connected networks go to an idle
state. If inadvertent, this can result in the loss of application control and/or
critical process diagnostic data. Rapid communication idle detection helps
minimize the potential damage due to uncontrolled or unmonitored
applications.
Comm Idle Trip
The EC4 Current Monitoring Relay will trip with a Comm Idle indication if:
• No trip currently exists
• Comm Idle protection is enabled
• The network controller that the EC4 Current Monitoring Relay is

Preventive Maintenance
Diagnostics
The purpose of this section is to provide detailed information regarding the
Preventive Maintenance Diagnostic functions of the EC4 Current Monitoring
Relays. 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 5-58.
Monitoring
Parameter 95, Elapsed Time, logs the hours of motor operation — the time
period that the EC4 Current Monitoring Relay is sensing motor current present
(must be greater than 30% of the minimum Full Load Current (FLA) setting).
Parameter 96, Starts Counter, logs the number of starts, defined as 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 EC4 Current Monitoring Relay will report 0 A or 0% FLA if the
current is below 30% of the minimum FLA setting.
Preventive Maintenance Flags
The EC4 Current Monitoring Relay offers preventive maintenance flags in the Wa r n i n g
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 EC4 Current Monitoring Relay will report 0 A or 0% FLA if the current
is below 30% of the minimum FLA setting.
The EC4 Current Monitoring Relay will give a PM - # Starts warning indication
when:
• PM - # Starts warning is enabled

The EC4 Current Monitoring Relay will give a PM – Oper. Hours warning
indication when:
• PM – Oper. Hours warning is enabled
• 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 following will occur:
• The TRIP/WARN LED will flash an amber 15-blink pattern
• Bit 14 in Parameter 15, War n in g S ta t us , will go to “1”
• Bit 1 in Parameter 21, Device Status, will go to “1”
Parameter 102, PM – Oper. Hours, allows the installer to set a number of hours of
operation. It is adjustable from 0…65,565 hours.
Queue Clearing
The EC4 Current Monitoring Relay provides the capability to clear the Tri p L o gs ,
Warning Logs, Starts Counter, and the Elapsed Time using the Clear Queue parameter. If using the Preventative Maintenance Flags, the user will want to reset the Starts Count and
Elapsed Time after preventative maintenance has been performed.
Parameter 104, Clear Queue, allows the user to clear the Trip Logs (parameters 16…20),
Warning Logs (parameters 90…94), Starts Counter (parameter 96), and the Elapsed Time
(parameter 95). The Clear Queue parameter will clear/reset all of these parameters at the
same time.

DeviceNet Node Commissioning
IMPORTANT
The following recommendations are intended to ensure a trouble-free
startup and operation:
1. Use the node commissioning tool in RSNetWorx or the E3 programming and
control terminal when modifying the E3’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.
2. Ensure that you have the most current configuration information prior to saving an
RSNetWorx configuration file.
3. If you intend to employ the ADR function of the DeviceNet scanner, ensure that
the device configuration is as you intend it BEFORE saving to memory.
4. Be aware that the “Restore Device Defaults” button in RSNetWorx will reset the
EC4 Current Monitoring 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
4
Introduction
EC4 Current Monitoring 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 the EC4
Current Monitoring Relay 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 and later)
Use the following steps to commission the card.
1. Set the node address switches.

Produced and Consumed Assembly Configuration
The Input and Output Assembly format for the EC4 Current Monitoring Relay
is identified by the value in parameter 59 (Output Assembly) and parameter 60
(Input Assembly). These values determine the amount and arrangement of the
information communicated to the master scanner.
54Rockwell Automation Publication 193-UM011A-EN-P - September 2010
Figure 30 - I/O Assembly Settings
DeviceNet Node Commissioning Chapter 4
Selection of Input and Output Assemblies (also referred to as Produced and
Consumed Assemblies) define the format of I/O message data that is exchanged
between the EC4 Current Monitoring Relay and other devices on the network.
The consumed information is generally used to command the state of the slave
device’s outputs, and produced information typically contains the state of the
inputs and the current fault status of the slave device.
The default Consumed and Produced Assemblies are shown in Table 14 and
Table 15; for additional formats refer to AppendixB.

Rockwell Automation Publication 193-UM011A-EN-P - September 201055
Choosing the size and format of the I/O data that is exchanged by the EC4
Current Monitoring 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.
The Output Assembly and Input Assembly parameter values cannot be
changed while the EC4 Current Monitoring 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”.
Mapping to the Scanner’s Scan List
The Automap feature available in all Rockwell Automation scanners
automatically maps the information. If the default I/O Assemblies are not used,
the values must be changed in the scanner’s Scan List.
Do this by selecting “Edit I/O Parameters” on the Scan List tab of the scanner.
The following screen (see Figure 31 -) then appears.

Introduction
Parameter Programming
Program Lock
This chapter describes each programmable parameter and its function.
Refer to Chapter 4 — DeviceNet Node Commissioning for instructions in
using RSNetworx for DeviceNet to modify parameter settings. The section,
Device Parameter Programming — Input and Output Assemblies, shows an
example of modifying Parameters 59 and 60.
Parameter setting changes downloaded to the EC4 Current Monitoring
Relay take effect immediately, even during a “running” status.
Parameter setting changes made in a configuration tool such as
RSNetWorx for DeviceNet do not take effect in the EC4 Current
Monitoring Relay until the installer applies or downloads the new
settings to the device.
Parameter 53, Program Lock, provides a degree of security from having parameter
settings unintentionally altered when programmed to the “locked” setting.
Resetting to the Factory
Default Values
Parameter Group Listing
Rockwell Automation Publication 193-UM011A-EN-P - September 201058
Parameter 54, Set to Defaults, allows the installer to reset all parameter settings
(including trip logs) to the factory default values.
Resetting to factory default values also resets the EC4 Current
Monitoring Relay’s DeviceNet node address (MAC ID) to the default
value of 63.
The EC4 Current Monitoring Relay contains six parameter groups. The
parameters shown in the Advanced Setup, DeviceNet Setup, Output Setup, and
Reset/Lock groups will be discussed in this chapter. The parameters in the
Monitor group will be discussed in Chapter 6 — Current Monitoring Parameters and Chapter 7 — Diagnostic Parameters. The parameters in the
Trip History and Snapshot groups will be discussed in Chapter 9 — Logic Controller Application Example with Explicit Messaging.

Chapter 5 Programmable Parameters
IMPORTANT
Output Setup Group
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 Parameter 24, Trip Enable, 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.
EC4 is normal – no trip present
In normal operation, the EC4 Current Monitoring 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.
EC4 is tripped
In the event of a protection trip, the state of an EC4 Current Monitoring 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.
The EC4 current monitoring relay sets the firmware latch to the Out_ Pr FltValue
when Out_ Pr FltState is set to “Go to FltValue” while the EC4 Current
Monitoring Relay is in a tripped state.
EC4 is reset from trip
After an EC4 Current Monitoring 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.Table 19 provides further illustration.
76Rockwell Automation Publication 193-UM011A-EN-P - September 2010
Table 19 - Output State Matrix for Output Setup Parameters
This parameter, in conjunction with

respond when a trip occurs. When set to “1”,
Output A will continue to operate as
commanded via the network. When set to

Introduction
Phase Current Reporting
This chapter provides information for the current monitoring parameters of the
EC4 Current Monitoring Relay.
Current Range
The EC4 Current Monitoring 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 and reporting currents ranging from 0% to 720% of the
maximum current rating.
The EC4 Current Monitoring Relay will report 0 A if the current is
below 30% of the minimum current rating.
The EC4 Current Monitoring Relay is capable of reporting values
greater than 720% of the maximum current rating, 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 current rating value
for each current range.

Logic Controller Application Example with
Explicit Messaging
Introduction
I/O Mapping
This example demonstrates discrete control of the EC4 Current Monitoring
Relay’s output relay and the use of the explicit messaging function for transferring
parameter data to a CompactLogix L32E via a 1769-SDN DeviceNet scanner
module named DNET. The selections shown are example-specific. Some changes
by the user may be necessary to apply the concepts of this example to a specific
application.
Figure 32 - Network Example
For this example, a CompactLogix L32E will energize OUT A on an EC4
Current Monitoring Relay using DeviceNet I/O Messaging. The EC4 is
configured as Node 6 on the DeviceNet network. Its Output Assembly is
configured to use Output Assembly 103, and its Input Assembly is configured to
use Input Assembly 100 as shown:
The 1769-SDN was configured to scan I/O from various devices, including the
EC4, and store this information to the following memory locations within the
CompactLogix L32E as shown:
Rockwell Automation Publication 193-UM011A-EN-P - September 201097
Chapter 9 Logic Controller Application Example with Explicit Messaging
To have the CompactLogix controller energize OUT A of the EC4 Current
Monitoring 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 EC4 Current Monitoring Relay was energized, the
CompactLogix controller will read the device status of the EC4 Current
Monitoring Relay and place that information at Word 1:I.Data[0] with the
L32E. Bit 2 identifies the state of OUT A.

Logic Controller Application Example with Explicit Messaging Chapter 9
For more information on configuring the scanlist of a DeviceNet Scanner, refer
to DeviceNet Node Commissioning on page 4-48.
Explicit Messaging
The EC4 Current Monitoring Relay supports Explicit Messaging via DeviceNet.
This allows a controller to read and write various parameters from an EC4
Current Monitoring Relay. In this example, a CompactLogix L32E controller
will read three parameters from the EC4 located on Node 6 on a DeviceNet via
Explicit Messaging using various Object Classes and storing the information in an
array of Integer_Files.
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 msec in which a message instruction will be used to read the Device
Status of the EC4 Current Monitoring Relay using the Parameter Object Class.
The supporting ladder logic was added to execute a MSG instruction every time
this Periodic Task executes
.
Rockwell Automation Publication 193-UM011A-EN-P - September 201099
Chapter 9 Logic Controller Application Example with Explicit Messaging
The Device Status is located in Parameter 21 within the EC4 Current
Monitoring Relay. Setup the MSG instruction in the Configuration tab to read
Parameter 21 using the Parameter Object Class by configuring the following
fields:
Next, set up the communications path in the Communication tab to read data
from the EC4 Current Monitoring Relay located at Node 6 by configuring the
communication Path as “DNET, 2, 6”
DNET - the name of the 1769-SDN DeviceNet Scanner
2 – The port number of the 1769-SDN DeviceNet Scanner
6 – The node address of the EC4 Current Monitoring Relay
When finished, the MSG instruction will read the Device Status from the EC4
Current Monitoring Relay and place the results in Integer_Files[0] as shown:
100Rockwell Automation Publication 193-UM011A-EN-P - September 2010
Logic Controller Application Example with Explicit Messaging Chapter 9
Currently OUT A of the EC4 Current Monitoring Relay is energized as shown
in Bit 2 in Integer_Files[0].
Reading Device Status using the Control Supervisor Object Class
(0x29)
In this example, a Periodic Task has been configured within the L32E to execute
every 1000 msec in which a message instruction will be used to read the Device
Status of the EC4 Current Monitoring Relay using the Control Supervisor
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 EC4 Current
Monitoring Relay. Set up the MSG instruction in the Configuration tab to read
Parameter 21 using the Parameter Object Class by configuring the following
fields:
– Message Type:CIP Generic
– Service Type: Get Attribute Single
– Service Code: 0x0E (hex)
– Class:0x29 (hex)
– Instance:0x01 (hex)
– Attribute:0x79 (hex)
