1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR
The GE Universal Relay (UR) series is a new generation of digital, modular, and multifunction equipment that is easily
incorporated into automation systems, at both the station and enterprise levels.
1.2.2 HARDWARE ARCHITECTURE
a) UR BASIC DESIGN
The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output
signals. The UR device can communicate over a local area network (LAN) with an operator interface, a programming
device, or another UR device.
1
Figure 1–2: UR BLOCK DIAGRAM
The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as programmable logic gates, timers, and latches for control features.
Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into
logic signals used by the relay.
Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used
to control field devices.
The software and unit are backwards-compatible with UR devices.
b) UR SIGNAL TYPES
The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’
contacts are supported.
The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.
The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec-
tors (RTDs).
The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines.
The UR-series relays support 1 A and 5 A CTs.
The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series
devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic operands inserted into IEC 61850 GSSE and GOOSE messages.

Set outputs
The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over
dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are con-
1
nected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilotaided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.
c) UR SCAN OPERATION
The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the
logic program (FlexLogic equation), and then sets each output to the appropriate state in an output status table. Any resulting task execution is priority interrupt-driven.

1 GETTING STARTED 1.2 UR OVERVIEW
1.2.3 SOFTWARE ARCHITECTURE
Firmware is the software embedded in the relay and is designed in functional modules that can be installed in any relay as
required. This is achieved with object-oriented design and programming (OOD/OOP) techniques.
Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains
both data and code that manipulates that data”. A class is the generalized form of similar objects. By using this concept,
one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instantaneous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent
completely self-contained software modules. The same object-class concept can be used for metering, input/output control,
software interface, communications, or any functional entity in the system.
Employing OOD/OOP in the software architecture of the L60 achieves the same features as the hardware architecture:
modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection,
transformer protection, distance protection) is constructed by combining objects from the various functional classes. This
results in a common interface across the UR series.
1.2.4 IMPORTANT CONCEPTS
As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understanding of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in
“elements”. A description of the UR-series elements can be found in the Introduction to elements section in chapter 5.
Examples of simple elements, and some of the organization of this manual, can be found in the Control elements section of
chapter 5. An explanation of the use of inputs from CTs and VTs is in the Introduction to AC sources section in chapter 5. A
description of how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic section in
chapter 5.

window, then click the button for the action they want to perform. The following quick action functions are available:
• View the L60 event record
• View the last recorded oscillography record
• View the status of all L60 inputs and outputs
• View all of the L60 metering values
• View the L60 protection summary
• Generate a service report

1.3.6 SETTING UP CYBERSENTRY AND CHANGING DEFAULT PASSWORD
1
If and when first using CyberSentry security, use the following procedure for set up.
1. Log in to the relay as Administrator by using the Value keys on the front panel or through EnerVista connected serially
(so that no IP address is required). If logging in through EnerVista choose Device authentication. Enter the default
password "ChangeMe1#". Note that the "Lock relay" setting needs to be disabled in the Security > Supervisory
menu. When this setting is disabled, configuration and firmware upgrade are possible. By default, this setting is disabled.
2. Enable the Supervisor role if you have a need for it.
3. Make any required changes in configuration, such as setting a valid IP address for communication over Ethernet.
4. Log out of the Administrator account by choosing None.
Next, device or server authentication can be chosen on the login screen, but the choice is available only in EnerVista. Use
device authentication to log in using the five pre-configured roles (Administrator, Supervisor, Engineer, Operator,
Observer). When using a serial connection, only device authentication is supported. When server authentication is
required, characteristics for communication with a RADIUS server must be configured on the UR. This is possible only
through the EnerVista software. The RADIUS server itself also must be configured. The appendix called RADIUS Server
gives an example of how to setup a simple RADIUS server. Once both the RADIUS server and the parameters for connecting UR to the server have been configured, you can choose server authentication on the login screen of EnerVista.
Figure 1–10: LOGIN SCREEN FOR CYBERSENTRY
During the commissioning phase, you have the option to bypass the use of passwords. Do so by enabling the Bypass
Access setting under
commissioning the device.
You can change the password for any role either from the front panel or through EnerVista.

1.4.2 COMMUNICATIONS
The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ethernet ports. To communicate via the faceplate RS232 port, a standard straight-through serial cable is used. The DB-9 male
end is connected to the relay and the DB-9 or DB-25 female end is connected to the computer COM2 port as described in
the CPU communications ports section of chapter 3.
Figure 1–12: RELAY COMMUNICATION OPTIONS
To communicate through the L60 rear RS485 port from a computer RS232 port, the GE Multilin RS232/RS485 converter
box is required. This device (catalog number F485) connects to the computer using a straight-through serial cable. A
shielded twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the L60 rear communications port. The converter
terminals (+, –, GND) are connected to the L60 communication module (+, –, COM) terminals. See the CPU communica-
tions ports section in chapter 3 for details. The line is terminated with an R-C network (that is, 120 Ω, 1 nF) as described in
the chapter 3.
All messages are displayed on a backlit liquid crystal display (LCD) to make them visible under poor lighting conditions.
While the keypad and display are not actively being used, the display defaults to user-defined messages. Any high-priority
event-driven message automatically overrides the default message and appears on the display.

1.5.7 COMMISSIONING
The L60 requires minimal maintenance after it is commissioned into service. Since the L60 is a microprocessor-based
relay, its characteristics do not change over time. As such, no further functional tests are required. Expected service life is
20 years for UR devices manufactured June 2014 or later when applied in a controlled indoors environment and electrical
conditions within specification.
The L60 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the
Relay Self-tests section in chapter 7). However, it is recommended that L60 maintenance be scheduled with other system
maintenance. This maintenance can involve in-service, out-of-service, or unscheduled maintenance.
In-service maintenance:
1. Visual verification of the analog values integrity, such as voltage and current (in comparison to other devices on the
corresponding system).
2. Visual verification of active alarms, relay display messages, and LED indications.
3. LED test.
4. Visual inspection for any damage, corrosion, dust, or loose wires.
5. Event recorder file download with further events analysis.
Out-of-service maintenance:
1. Check wiring connections for firmness.
2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated
test equipment is required.
3. Protection elements setting verification (analog values injection or visual verification of setting file entries against relay
settings schedule).
4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the
system functional testing.
5. Visual inspection for any damage, corrosion, or dust.
6. Event recorder file download with further events analysis.
7. LED Test and pushbutton continuity check.
Unscheduled maintenance, such as a disturbance causing system interruption:
1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements.
If it is concluded that the relay or one of its modules is of concern, contact GE Multilin for service.

2 PRODUCT DESCRIPTION 2.1 INTRODUCTION
2 PRODUCT DESCRIPTION 2.1INTRODUCTION 2.1.1 OVERVIEW
The L60 Line Phase Comparison System provides a simple phase-comparison principle successfully employed by analog
and static relays for many years along with the significant advantages of a modern microprocessor based relay. The phase
comparison element performs the following calculations:
• Samples and filters three-phase AC currents at a rate of 64 samples per cycle.
• Computes sequence components of the current.
• If two CT/VT modules are employed for breaker-and-a-half applications, the relay sums up two currents and performs
the breaker-and-the-half logic calculations.
• Forms a composite signal from current components according to a user-defined setting.
• Forms local positive and negative squares from the composite signal sent to remote terminal and used locally along
with the channel delay value.
• Samples received from remote terminal squares 64 samples per cycle measuring magnitude of the pulse voltage.
• Processes received samples to compensate for asymmetry and distortions in the signal.
• Detects fault condition with the fault detector.
• Compares coincidence of local and remote squares which indicate the presence of internal or external faults.
• Detects transient conditions to block the phase comparison function.
All processed signals, including transmitted and received pulses, are available in oscillography for commissioning, maintenance, and analysis. The L60 integrates received pulses on a sample-per-sample base, similar to the analog phase-comparison principle, making the relay exceptionally robust on noisy channels. All permissive and blocking schemes, as well as
single and dual phase comparison, are incorporated into a single protection element and can be selected with a relay setting. The L60 supports two and three-terminal applications, can be used for single- and three-pole tripping applications, and
supports breaker-and-a-half applications. Multiple backup functions include three-zone phase and ground distance, directional overcurrent, pilot schemes, and current and voltage elements.
Control features include synchrocheck, autoreclosure, and control for two breakers. Monitoring features include CT failure
detector, VT fuse failure detector, breaker arcing current, disturbance detector and continuous monitor.
Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of storing
up to 64 records with programmable trigger, content and sampling rate, and data logger acquisition of up to 16 channels,
with programmable content and sampling rate. The internal clock used for time-tagging can be synchronized with an IRIGB signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using the Precision Time Protocol
(PTP). This precise time stamping allows the sequence of events to be determined throughout the system. Events can also
be programmed (via FlexLogic™ equations) to trigger oscillography data capture which may be set to record the measured
parameters before and after the event for viewing on a personal computer (PC). These tools significantly reduce troubleshooting time and simplify report generation in the event of a system fault.
Several options are available for communication. A faceplate RS232 port can be used to connect to a computer for the programming of settings and the monitoring of actual values. The RS232 port has a fixed baud rate of 19.2 kbps. The rear
RS485 port allows independent access by operating and engineering staff. It can be connected to system computers with
baud rates up to 115.2 kbps. All serial ports use the Modbus RTU protocol. The 100Base-FX or 100Base-T Ethernet interface provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, Modbus/TCP,
and TFTP protocols, PTP (according to IEEE Std. 1588-2008 or IEC 61588), and allows access to the relay via any standard web browser (L60 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC
60870-5-104 cannot be enabled at the same time. The Ethernet port also supports the Parallel Redundancy Protocol (PRP)
of IEC 62439-3 (clause 4, 2012) when purchased as an option.
Settings and actual values can be accessed from the front panel or EnerVista software.
Typical two-terminal and three-terminal applications are shown below.

2.1.2 SECURITY
The following security features are available:
• Password security — Basic security present in the default offering of the product
• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The feature is available in the default offering of the product and only in the EnerVista software.
• CyberSentry security — Advanced security options available as a software option. When purchased, the options are
automatically enabled, and the default Password security and EnerVista security are disabled.
Changing the password, or any other setting, does not take the relay out of service. The relay is taken out of service when
a settings file is written to it.
a) ENERVISTA SECURITY
The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security management
system is disabled by default to allow the administrator direct access to the EnerVista software after installation. It is recommended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
b) PASSWORD SECURITY
Password security is a basic security feature present in the default offering of the product.
Two levels of password security are provided: command and setting.
The following operations are under command password supervision:
• Operating the breakers via faceplate keypad
2-4 L60 Line Phase Comparison System GE Multilin
Page 37
2 PRODUCT DESCRIPTION 2.1 INTRODUCTION
• Changing the state of virtual inputs
• Clearing the event records
• Clearing the oscillography records
• Clearing fault reports
• Changing the date and time
• Clearing the breaker arcing current
• Clearing energy records
• Clearing the data logger
• Clearing the user-programmable pushbutton states
The following operations are under setting password supervision:
• Changing any setting
• Test mode operation
The L60 supports password entry from a local or remote connection. Local access is defined as any access to settings or
commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote
access is defined as any access to settings or commands via any rear communications port. This includes both Ethernet
and RS485 connections. Any changes to the local or remote passwords enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the corresponding connection password. If the connection is to the back of the L60, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password applies.
Password access events are logged in the Event Recorder.
2
c) CYBERSENTRY SECURITY
CyberSentry Embedded Security is a software option that provides advanced security services. When this option is purchased, the basic password security is disabled automatically.
CyberSentry provides security through the following features:
• An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that
is centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standardsbased strong cryptography for authentication and credential protection.
• A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device oper-
ations and configurations based on specific roles and individual user accounts configured on the AAA server (that is,
Administrator, Supervisor, Engineer, Operator, Observer).
• Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring.
• Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the
National Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems.

Administrator
Engineer
Supervisor
Operator
Observer
Example: Administrative functions can be segmented away from common operator functions, or engineering type access,
all of which are defined by separate roles, as shown in the following figure, so that access of UR devices by multiple personnel within a substation is allowed. Permission for each role are outlined in the next section.
Figure 2–3: CYBERSENTRY USER ROLES
2
There are two types of authentication supported by CyberSentry that can be used to access the UR device:
• Device Authentication (local UR device authenticates)
• Server Authentication (RADIUS server authenticates)
The EnerVista software allows access to functionality that is determined by the user role, which comes either from the local
UR device or RADIUS server.
The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the
"Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the
user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator) as login names and the
associated passwords are stored on the UR device. As such, when using the local accounts, access is not user-attributable.
In cases where user attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication only.
When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication
database to authenticate the user.
No password or security information are displayed in plain text by the EnerVista software or UR device, nor are they ever
transmitted without cryptographic protection.
CYBERSENTRY USER ROLES
CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR
device functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in
role.
Example: Observer cannot write any settings.
The table lists the roles that are supported and their corresponding capabilities.

CYBERSENTRY SERVER AUTHENTICATION
The UR has been designed to automatically direct authentication requests based on user names. In this respect, local
account names on the UR are considered as reserved, and not used on a RADIUS server.
The UR automatically detects whether an authentication request is to be handled remotely or locally. As there are only five
local accounts possible on the UR, if the user ID credential does not match one of the five local accounts, the UR automatically forwards the request to a RADIUS server when one is provided.
If a RADIUS server is provided, but is unreachable over the network, server authentication requests are denied. In this situation, use local UR accounts to gain access to the UR system.

The L60 is available as a 19-inch rack horizontal mount unit or a reduced size (¾) vertical mount unit, and consists of the
following modules: CPU, faceplate, power supply, CPU, CTs and VTs, digital input and outputs, transducer inputs and outputs, and inter-relay communications. Each of these modules can be supplied in a number of configurations specified at the
time of ordering. The information required to completely specify the relay is provided in the following tables (see chapter 3
for additional details of relay modules).
The L60 is specified with two CT/VT modules (8F and 8P). When the L60 is applied in two-breaker configurations (such as
breaker-and-a-half or ring configurations), the currents from the two CTs are summed internally within the relay or externally. If the voltage is not supplies to the relay, some functions (such as distance, undervoltage, and synchrocheck) will not
be available.
Order codes are subject to change without notice. See the GE Multilin ordering page at
http://www.gedigitalenergy.com/multilin/order.htm
for the latest options.
The order codes for the horizontal mount units are shown below.

The power budgets for the 1300 nm ELED are calculated from the manufacturer's transmitter power and
receiver sensitivity at ambient temperature. At
extreme temperatures these values deviate based
on component tolerance. On average, the output
power decreases as the temperature is increased by
a factor 1dB / 5°C.

Normally, cleaning is not required; but for situations where dust
has accumulated on the faceplate display, a dry cloth can be used.
To avoid deterioration of electrolytic
capacitors, power up units that are stored
in a de-energized state once per year, for
one hour continuously.

3.1.2 REAR TERMINAL LAYOUT
3
The relay follows a convention with respect to terminal number assignments which are three characters long assigned in
order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the
first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following
figure for an example of rear terminal assignments.
Figure 3–8: REAR TERMINAL VIEW
Do not touch any rear terminals while the relay is energized.
The small form-factor pluggable ports (SFPs) are pluggable transceivers. Do not use non-validated
transceivers or install validated transceivers in the wrong Ethernet slot, else damage can occur.

Filter networks and transient protection clamps are used in the hardware to prevent damage caused
by high peak voltage transients, radio frequency interference (RFI), and electromagnetic interference
(EMI). These protective components can be damaged by application of the ANSI/IEEE C37.90 specified test voltage for a period longer than the specified one minute.

3.2.3 CONTROL POWER
Control power supplied to the relay must be connected to the matching power supply range of the
relay. If voltage is applied to the wrong terminals, damage can occur.
The L60 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are
well-known to deteriorate over time if voltage is not applied periodically. Deterioration can be avoided
by powering up the relay at least once a year.
The power supply module can be ordered for two possible voltage ranges, and the UR can be ordered with or without a
redundant power supply module option. Each range has a dedicated input connection for proper operation. The ranges are
as shown below (see the Technical specifications section of chapter 2 for additional details):
• Low (LO) range: 24 to 48 V (DC only) nominal
• High (HI) range: 125 to 250 V nominal
The power supply module provides power to the relay and supplies power for dry contact input connections.
The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the
Typical wiring diagram earlier). The critical failure relay is a form-C device that is energized once control power is applied
and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks detect a
critical failure (see the Self-test errors section in chapter 7) or control power is lost, the relay is de-energize.
For high reliability systems, the L60 has a redundant option in which two L60 power supplies are placed in parallel on the
bus. If one of the power supplies become faulted, the second power supply assumes the full load of the relay without any
interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay
of the module also indicates a faulted power supply.

3.2.4 CT AND VT MODULES
A CT/VT module can have voltage or current inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive.
Channels 1 and 5 are intended for connection to phase A, and are labeled as such in the relay. Likewise, channels 2 and 6
are intended for connection to phase B, and channels 3 and 7 are intended for connection to phase C.
Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channel are labelled as
auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neutral and
ground, and are labelled as ground current (IG).
Verify that the connection made to the relay terminals for nominal current of 1 A or 5 A matches the
secondary rating of the connected CTs. Unmatched CTs can result in equipment damage or inade-
quate protection.
To connect the module, size 12 American Wire Gauge (AWG) is commonly used; the maximum size is 10 AWG.
CT/VT modules can be ordered with a standard ground current input that is the same as the phase current input. Each AC
current input has an isolating transformer and an automatic shorting mechanism that shorts the input when the module is
withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 to
50000 A primaries and 1 A or 5 A secondaries can be used.
The above modules have enhanced diagnostics that can automatically detect CT/VT hardware failure and take the relay
out of service.
CT connections for both ABC and ACB phase rotations are identical as shown in the Typical wiring diagram.
The phase voltage channels are used for most metering and protection purposes. The auxiliary voltage channel is used as
input for the synchrocheck and volts-per-hertz features.
The L60 uses a special CT/VT module not available on other UR-series relays. This type 8P module has four current inputs
and special communications inputs/outputs for interfacing with PLCs. The communications interface requires an external
DC source (station battery) to drive inputs/outputs as shown in the L60 channel communications section in this chapter.

3.2.5 CONTACT INPUTS AND OUTPUTS
3
Every contact input/output module has 24 terminal connections. They are arranged as three terminals per row, with eight
rows in total. A given row of three terminals can be used for the outputs of one relay. For example, for form-C relay outputs,
the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a form-A
output, there are options of using current or voltage detection for feature supervision, depending on the module ordered.
The terminal configuration for contact inputs is different for the two applications.
The contact inputs are grouped with a common return. The L60 has two versions of grouping: four inputs per common
return and two inputs per common return. When a contact input/output module is ordered, four inputs per common is used.
If the inputs must be isolated per row, then two inputs per common return should be selected (4D module).
The tables and diagrams on the following pages illustrate the module types (6A, etc.) and contact arrangements that can be
ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot
position and row number. However, since there are two contact inputs per row, these names are assigned by module slot
position, row number, and column position.
Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is open,
and the DC current through the output contact when it is closed. Each of the monitors contains a level detector whose output is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On =
1” when there is a voltage across open contact (the detector allows a current of about 1 to 2.5 mA), and the current monitor
is set to “On = 1” when the current flowing through the closed contact exceeds about 80 to 100 mA. The voltage monitor is
intended to check the health of the overall trip circuit, and the current monitor can be used to seal-in the output contact until
an external contact has interrupted current flow. If enabled, the current monitoring can be used as a seal-in signal to ensure
that the form-A contact does not attempt to break the energized inductive coil circuit and weld the output contacts.
Block diagrams are shown as follows for form-A and solid-state relay outputs with optional voltage monitor, optional current
monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact outputs. Form-A
contact output with or without a current or voltage monitoring option is not polarity sensitive. The polarity shown in the figure
is required for solid-state contact output connection.

Figure 3–13: FORM-A AND SOLID-STATE CONTACT OUTPUTS WITH VOLTAGE AND CURRENT MONITORING
The operation of voltage and current monitors is reflected with the corresponding FlexLogic operands (CONT OP # VON,
CONT OP # VOFF, and CONT OP # ION) which can be used in protection, control, and alarm logic. The typical application of
the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the
control command.
Refer to the Digital elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be
applied for breaker trip circuit integrity monitoring.
Consider relay contacts unsafe to touch when the unit is energized.
USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH IMPEDANCE CIRCUITS
For form-A and solid-state relay output contacts internally equipped with a voltage measuring circuit across the contact, the circuit has an impedance that can cause a problem when used in conjunction with external high input
impedance monitoring equipment such as modern relay test set trigger circuits. These monitoring circuits may continue to read the form-A contact as being closed after it has closed and subsequently opened, when measured as
an impedance.
The solution is to use the voltage measuring trigger input of the relay test set, and connect the form-A contact
through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is used as a
source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the form-A contact or
the resistor can be used to monitor the state of the output.
Wherever a tilde “~” symbol appears, substitute with the slot position of the module; wherever a number sign “#”
appears, substitute the contact number
When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, the FlexLogic operand driving the contact output should be given a reset delay of 10 ms to prevent damage
of the output contact (in situations when the element initiating the contact output is bouncing, at values in the region of the pickup value).

CONTACT INPUTS
A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the power supply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group
has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply
module. When a dry contact closes, a current of 1 to 3 mA flows through the associated circuit.
A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact
is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external source
must be connected to the relay common (negative) terminal of each contact group. The maximum external source voltage
for this arrangement is 300 V DC.
The voltage threshold at which each group of four contact inputs detects a closed contact input is programmable as
17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

Wherever a tilde “~” symbol appears, substitute with the slot position of the module.
There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We recommend
using an external DC supply.

USE OF CONTACT INPUTS WITH AUTO-BURNISHING
The contact inputs sense a change of the state of the external device contact based on the measured current. When external devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to various types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface
of the contacts, sometimes making it difficult or impossible to detect a change of the state. This film must be removed to
establish circuit continuity – an impulse of higher than normal current can accomplish this.
The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation
layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The
impulse has a 5 second delay after a contact input changes state.
3
Figure 3–17: CURRENT THROUGH CONTACT INPUTS WITH AUTO-BURNISHING
Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with autoburnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within 25 to
50 ms, this current is slowly reduced to 3 mA as indicated above. The 50 to 70 mA peak current burns any film on the contacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts
when external device contact bouncing is over.
Another important difference between the auto-burnishing input module and the regular input modules is that only two contact inputs have common ground, as opposed to four contact inputs sharing one common ground (refer to the Contact Input
and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources. Consequently, the threshold voltage setting is also defined per group of two contact inputs.
The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP
switch for each contact, for a total of 16 inputs.

3.2.6 TRANSDUCER INPUTS AND OUTPUTS
Transducer input modules can receive input signals from external DCmA output transducers (dcmA In) or resistance temperature detectors (RTDs). Hardware and software are provided to receive signals from these external transducers and
convert these signals into a digital format for use as required.
Transducer output modules provide DC current outputs in several standard DCmA ranges. Software is provided to configure virtually any analog quantity used in the relay to drive the analog outputs.
Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three terminals per row with a total of eight rows. A given row can be used for either inputs or outputs, with terminals in column "a"
having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/
output channel, the name of the channel is assigned using the module slot position and row number.
Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs
require a twisted-pair shielded cable, where the shield is grounded at one end only. The following figure illustrates the transducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that can be ordered for the relay.
Wherever a tilde “~” symbol appears, substitute with the slot position of the module.

b) RS485 PORTS
RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternating over the same two wires. Through the use of the port, continuous monitoring and control from a remote computer,
SCADA system, or PLC is possible.
To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be
observed. For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–”
terminals connected together. Though data is transmitted over a two-wire twisted pair, all RS485 devices require a shared
reference, or common voltage. This common voltage is implied to be a power supply common. Some systems allow the
shield (drain wire) to be used as common wire and to connect directly to the L60 COM terminal (#3); others function correctly only if the common wire is connected to the L60 COM terminal, but insulated from the shield.
To avoid loop currents, ground the shield at only one point. If other system considerations require the shield to be grounded
at more than one point, install resistors (typically 100 ohms) between the shield and ground at each grounding point. Each
relay needs to be daisy-chained to the next one in the link. A maximum of 32 relays can be connected in this manner without exceeding driver capability. For larger systems, additional serial channels must be added. It is also possible to use commercially available repeaters to have more than 32 relays on a single channel. Avoid star or stub connections entirely.

Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the

3.3DIRECT INPUT AND OUTPUT COMMUNICATIONS 3.3.1 DESCRIPTION
The direct inputs and outputs feature makes use of the type 7 series of communications modules, which allow direct messaging between UR devices. These communications modules are outlined in the table later in this section.
The communications channels are normally connected in a ring configuration as shown in the following figure. The transmitter of one module is connected to the receiver of the next module. The transmitter of this second module is then connected to the receiver of the next module in the ring. This is continued to form a communications ring. The figure illustrates
a ring of four UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to UR4-Rx,
and UR4-Tx to UR1-Rx. A maximum of 16 UR-series relays can be connected in a single ring
Figure 3–26: DIRECT INPUT AND OUTPUT SINGLE CHANNEL CONNECTION
The interconnection for dual-channel type 7 communications modules is shown as follows. Two channel modules allow for
a redundant ring configuration. That is, two rings can be created to provide an additional independent data path. The
required connections are: UR1-Tx1 to UR2-Rx1, UR2-Tx1 to UR3-Rx1, UR3-Tx1 to UR4-Rx1, and UR4-Tx1 to UR1-Rx1
for the first ring; and UR1-Tx2 to UR4-Rx2, UR4-Tx2 to UR3-Rx2, UR3-Tx2 to UR2-Rx2, and UR2-Tx2 to UR1-Rx2 for the
second ring.

Figure 3–27: DIRECT INPUT AND OUTPUT DUAL CHANNEL CONNECTION
The following diagram shows the connection for three UR-series relays using two independent communication channels.
UR1 and UR3 have single type 7 communication modules; UR2 has a dual-channel module. The two communication channels can be of different types, depending on the type 7 modules used. To allow the direct input and output data to cross-
over from channel 1 to channel 2 on UR2, the
DIRECT I/O CHANNEL CROSSOVER setting should be “Enabled” on UR2. This
forces UR2 to forward messages received on Rx1 out Tx2, and messages received on Rx2 out Tx1.

3.3.4 G.703 INTERFACE
a) DESCRIPTION
The following figure shows the 64K ITU G.703 co-directional interface configuration.
The G.703 module is fixed at 64 kbps. The SETTINGS > PRODUCT SETUP > DIRECT I/O > DIRECT I/O DATA
RATE setting is not applicable to this module.
AWG 24 twisted shielded pair is recommended for external connections, with the shield grounded only at one end. Connecting the shield to pin X1a or X6a grounds the shield since these pins are internally connected to ground. Thus, if pin X1a
or X6a is used to ground the shield at one end, do not ground the shield at the other end. This interface module is protected
3
by surge suppression devices.
The following figure shows the typical pin interconnection between two G.703 interfaces. For the actual physical arrangement of these pins, see the Rear terminal assignments section earlier in this chapter. All pin interconnections are to be
maintained for a connection to a multiplexer.

c) G.703 OCTET TIMING
ON → octet timing 8 kHz
S5 = ON and S6 = OFF → internal timing mode
S5 = OFF and S6 = ON → minimum remote loopback mode
S5 = ON and S6 = ON → dual loopback mode
If octet timing is enabled (ON), this 8 kHz signal is asserted during the violation of bit 8 (LSB) necessary for connecting to
higher order systems. When L60s are connected back-to-back, octet timing is disabled (OFF).
d) G.703 TIMING MODES
There are two timing modes for the G.703 module: internal timing mode and loop timing mode (default).
• Internal Timing Mode: The system clock is generated internally. Therefore, the G.703 timing selection should be in
the internal timing mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set for octet timing
(S1 = OFF) and timing mode to internal timing (S5 = ON and S6 = OFF).

• Loop Timing Mode: The system clock is derived from the received line signal. Therefore, the G.703 timing selection
should be in loop timing mode for connections to higher order systems. For connection to a higher order system (URto-multiplexer, factory defaults), set to octet timing (S1 = ON) and set timing mode to loop timing (S5 = OFF and S6 =
OFF).
The switch settings for the internal and loop timing modes are shown below:

e) G.703 TEST MODES
In minimum remote loopback mode, the multiplexer is enabled to return the data from the external interface without any
processing to assist in diagnosing G.703 line-side problems irrespective of clock rate. Data enters from the G.703 inputs,
passes through the data stabilization latch which also restores the proper signal polarity, passes through the multiplexer
and then returns to the transmitter. The differential received data is processed and passed to the G.703 transmitter module
after which point the data is discarded. The G.703 receiver module is fully functional and continues to process data and
passes it to the differential Manchester transmitter module. Since timing is returned as it is received, the timing source is
expected to be from the G.703 line side of the interface.
In dual loopback mode, the multiplexers are active and the functions of the circuit are divided into two with each receiver/
transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data
enters the Differential Manchester receiver module and then is returned to the differential Manchester transmitter module.
Likewise, G.703 data enters the G.703 receiver module and is passed through to the G.703 transmitter module to be
returned as G.703 data. Because of the complete split in the communications path and because, in each case, the clocks
are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing. One
source lies on the G.703 line side of the interface while the other lies on the differential Manchester side of the interface.

3.3.5 RS422 INTERFACE
a) DESCRIPTION
There are two RS422 inter-relay communications modules available: single-channel RS422 (module 7T) and dual-channel
RS422 (module 7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 20-24 twisted shielded pair cable
is recommended for external connections. These modules are protected by optically-isolated surge suppression devices.
The shield pins (6a and 7b) are internally connected to the ground pin (8a). Proper shield termination is as follows:
• Site 1: Terminate shield to pins 6a or 7b or both.
• Site 2: Terminate shield to COM pin 2b.
Match the clock terminating impedance with the impedance of the line.

The following figure shows the typical pin interconnection between two single-channel RS422 interfaces installed in slot W.
All pin interconnections are to be maintained for a connection to a multiplexer.
b) TWO-CHANNEL APPLICATION VIA MULTIPLEXERS
The RS422 interface can be used for single channel or two channel applications over SONET/SDH or multiplexed systems.
When used in single-channel applications, the RS422 interface links to higher order systems in a typical fashion observing
transmit (Tx), receive (Rx), and send timing (ST) connections. However, when used in two-channel applications, certain criteria must be followed since there is one clock input for the two RS422 channels. The system functions correctly when the
following connections are observed and your data module has a terminal timing feature. Terminal timing is a common feature to most synchronous data units that allows the module to accept timing from an external source. Using the terminal
timing feature, two channel applications can be achieved if these connections are followed: The send timing outputs from
the multiplexer (data module 1), connects to the clock inputs of the UR–RS422 interface in the usual fashion. In addition,
the send timing outputs of data module 1 is also paralleled to the terminal timing inputs of data module 2. By using this configuration, the timing for both data modules and both UR–RS422 channels are derived from a single clock source. As a
result, data sampling for both of the UR–RS422 channels is synchronized via the send timing leads on data module 1 as
shown below. If the terminal timing feature is not available or this type of connection is not desired, the G.703 interface is a
viable option that does not impose timing restrictions.

Figure 3–38: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, THREE-TERMINAL APPLICATION
Data module 1 provides timing to the L60 RS422 interface via the ST(A) and ST(B) outputs. Data module 1 also provides
timing to data module 2 TT(A) and TT(B) inputs via the ST(A) and AT(B) outputs. The data module pin numbers have been
omitted in the figure above since they vary by manufacturer.
c) TRANSMIT TIMING
The RS422 interface accepts one clock input for transmit timing. It is important that the rising edge of the 64 kHz transmit
timing clock of the multiplexer interface is sampling the data in the center of the transmit data window. Therefore, it is important to confirm clock and data transitions to ensure proper system operation. For example, the following figure shows the
positive edge of the Tx clock in the center of the Tx data bit.

d) RECEIVE TIMING
The RS422 interface utilizes NRZI-MARK modulation code and; therefore, does not rely on an Rx clock to recapture data.
NRZI-MARK is an edge-type, invertible, self-clocking code.
To recover the Rx clock from the data-stream, an integrated DPLL (digital phase lock loop) circuit is utilized. The DPLL is
driven by an internal clock, which is 16-times over-sampled, and uses this clock along with the data-stream to generate a
data clock that can be used as the SCC (serial communication controller) receive clock.
3.3.6 RS422 AND FIBER INTERFACE
The following figure shows the combined RS422 plus fiberoptic interface configuration at 64K baud. The 7L, 7M, 7N, 7P,
and 74 modules are used in two-terminal with a redundant channel or three-terminal configurations where channel 1 is
employed via the RS422 interface (possibly with a multiplexer) and channel 2 via direct fiber.
AWG 20-24 twisted shielded pair is recommended for external RS422 connections and ground the shield only at one end.
For the direct fiber channel, address power budget issues properly.
When using a LASER Interface, attenuators can be necessary to ensure that you do not exceed
maximum optical input power to the receiver.

The figure below shows the combined G.703 plus fiberoptic interface configuration at 64 kbps. The 7E, 7F, 7G, 7Q, and 75
modules are used in configurations where channel 1 is employed via the G.703 interface (possibly with a multiplexer) and
channel 2 via direct fiber. AWG 24 twisted shielded pair is recommended for external G.703 connections connecting the
shield to pin 1a at one end only. For the direct fiber channel, address power budget issues properly. See previous sections
for additional details on the G.703 and fiber interfaces.
When using a laser Interface, attenuators can be necessary to ensure that you do not exceed the

3.3.8 IEEE C37.94 INTERFACE
The UR-series IEEE C37.94 communication modules (modules types 2G, 2H, 76, and 77) are designed to interface with
IEEE C37.94 compliant digital multiplexers or an IEEE C37.94 compliant interface converter for use with direct input and
output applications. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps,
where n = 1, 2,…, 12. The UR-series C37.94 communication modules are either 64 kbps (with n fixed at 1) for 128 kbps
(with n fixed at 2). The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from
the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit
rate of 2048 kbps.
The specifications for the module are as follows:.
• IEEE standard: C37.94 for 1 × 128 kbps optical fiber interface (for 2G and 2H modules) or C37.94 for 2 × 64 kbps opti-
cal fiber interface (for 76 and 77 modules)
• Fiber optic cable type: 50 nm or 62.5 µm core diameter optical fiber
• Fiber optic mode: multi-mode
• Fiber optic cable length: up to 2 km
• Fiber optic connector: type ST
• Wavelength: 820 ±40 nm
• Connection: as per all fiber optic connections, a Tx to Rx connection is required
The UR-series C37.94 communication module can be connected directly to any compliant digital multiplexer that supports
the IEEE C37.94 standard as shown below.

The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a
non-compliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard, as
shown below.
In 2008, GE Digital Energy released revised modules 76 and 77 for C37.94 communication to enable multi-ended fault
location functionality with firmware 5.60 release and higher. All modules 76 and 77 shipped since the change support this
feature and are fully backward compatible with firmware releases below 5.60. For customers using firmware release 5.60
and higher, the module can be identified with "Rev D" printed on the module and is to be used on all ends of L60 communication for two and three terminal applications. Failure to use it at all ends results in intermittent communication alarms. For
customers using firmware revisions below 5.60, it is not required to match the revision of the modules installed.
The UR-series C37.94 communication module has six switches that are used to set the clock configuration. The functions
of these control switches are shown below.

For the internal timing mode, the system clock is generated internally. Therefore, the timing switch selection should be
internal timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.
For the looped timing mode, the system clock is derived from the received line signal. Therefore, the timing selection
should be in loop timing mode for connections to higher order systems.
The IEEE C37.94 communications module cover removal procedure is as follows:
1. With power to the relay off, remove the IEEE C37.94 module (type 2G, 2H, 76 or 77 module) as follows. Record the
original location of the module to help ensure that the same or replacement module is inserted into the correct slot.
2. Simultaneously pull the ejector/inserter clips located at the top and at the bottom of each module in order to release the
module for removal.
3. Remove the module cover screw.
4. Remove the top cover by sliding it towards the rear and then lift it upwards.
5. Set the timing selection switches (channel 1, channel 2) to the desired timing modes (see description above).
6. Replace the top cover and the cover screw.
7. Re-insert the IEEE C37.94 module. Take care to ensure that the correct module type is inserted into the correct slot
position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis,
engage the clips simultaneously. When the clips have locked into position, the module is fully inserted.

The UR-series C37.94SM communication modules (2A and 2B) are designed to interface with modified IEEE C37.94 compliant digital multiplexers or IEEE C37.94 compliant interface converters that have been converted from 820 nm multi-mode
fiber optics to 1300 nm ELED single-mode fiber optics. The IEEE C37.94 standard defines a point-to-point optical link for
synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94SM communication module is 64 kbps only
with n fixed at 1. The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from
the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit
rate of 2048 kbps.
The specifications for the module are as follows:
• Emulated IEEE standard: emulates C37.94 for 1 × 64 kbps optical fiber interface (modules set to n = 1 or 64 kbps)
• Fiber optic cable type: 9/125 μm core diameter optical fiber

• Fiber optic mode: single-mode, ELED compatible with HP HFBR-1315T transmitter and HP HFBR-2316T receiver
• Fiber optic cable length: up to 11.4 km
• Fiber optic connector: type ST
• Wavelength: 1300 ±40 nm
• Connection: as per all fiber optic connections, a Tx to Rx connection is required
The UR-series C37.94SM communication module can be connected directly to any compliant digital multiplexer that sup-
ports C37.94SM as shown below.
It can also can be connected directly to any other UR-series relay with a C37.94SM module as shown below.
