Product Overview Chapter 1
Diagnostic Parameters
Trip Relay
Inputs and Outputs
The EC4 Current Monitoring Relay allows the user to monitor the following diagnostic information over the DeviceNet network:
Device status
Tri p s tat us
Wa rn in g s ta tu s
Elapsed Time
Operating Hours
History of past 5 trips and warnings
Refer to Chapter 7 — Diagnostic Parameters for detailed information of these parameters.
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.

NETWORK STATUS
TRIP / WARN
OUT A OUT B IN 1 IN 3
IN 2 IN 4
ATTENTION: The state of the outputs during a Protection Fault, DeviceNet Comm Fault, or a DeviceNet Comm Idle may be 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.
OUT A and B: These amber LEDs illuminate when the output contacts are commanded closed.
IN 1…4: These amber LEDs illuminate when the user-connected device contact is closed.
Test/Reset Button
14 Rockwell Automation Publication 193-UM011A-EN-P - September 2010
The Test/Reset button located on the front of the EC4 Current Monitoring Relay allows the user to perform the following:
Product Overview Chapter 1
Te s t : If Tes t E na bl e is enabled, the trip relay contact will open if the EC4 Current Monitoring Relay is in an un-tripped condition and the Test/Reset button is pressed. The Test/Reset button must be pressed for a minimum of 2 seconds to activate the test function.
Reset: The trip relay contact will close if the EC4 Current Monitoring Relay is in a tripped condition, the cause of the trip is no longer present, and the Test/Reset button is pressed.
ATTENTION: The “Test” function associated with the Test/Reset button is enabled by default. Activating it while a motor is operating will cause the starting contactor to drop out and stop motor operation.
Node Address Switches
DeviceNet Compatibility
Flash Memory
The node address switches located on the front of the EC4 Current Monitoring Relay provides physical means for setting the device node address value. Switch settings greater than 63 allow the node address to be software configured.

External Line Current Transformer Application
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

±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.

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.

Protective Trip and Warning Functions

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 2010 36
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.

Overcurrent Warning
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

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
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
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.

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

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 2010 39
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.

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.

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
The EC4 Current Monitoring Relay will trip with a Comm Fault indication if:
No trip currently exists
Comm Fault protection is enabled
The EC4 Current Monitoring Relay experiences a loss of communication
If the relay trips on a Comm Fault, the following will occur:
The Network Status LED will blink red or become solid red
The TRIP/WARN LED will flash a red 10-blink pattern
Bit 9 in Parameter 14, Trip Stat us , will go to “1”

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
communicating to is placed to program mode
If the relay trips on a Comm Idle, the following will occur:
The TRIP/WARN LED will flash a red 11-blink pattern
Bit 10 in Parameter 14, Tri p S tatu s, will go to “1”

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
46 Rockwell Automation Publication 193-UM011A-EN-P - September 2010
Protective Trip and Warning Functions Chapter 3
Starts Counter parameter is equal to or greater than the value set in the PM
- # Starts parameter
Upon a PM - # Starts warning, the following will occur:
The TRIP/WARN LED will flash an amber 14-blink pattern
Bit 13 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 101, PM - # Starts, allows the installer to set a number of starts. It is adjustable from 0…65,535.
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.
54 Rockwell Automation Publication 193-UM011A-EN-P - September 2010

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 AppendixB.

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 2010 58
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.

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 2010 97
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.
98 Rockwell Automation Publication 193-UM011A-EN-P - September 2010
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 2010 99
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:
Message Type: CIP GenericService Type: Parameter ReadService Code: 0x0E (hex)Class: 0x0F (hex)Instance: 21 (dec)Attribute: 0x01 (hex)Destination: Integer_Files[0]
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:
100 Rockwell 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 GenericService Type: Get Attribute SingleService Code: 0x0E (hex)Class: 0x29 (hex)Instance: 0x01 (hex)Attribute: 0x79 (hex)
