ADDENDUM
This Addendum contains information that relates to the L60 Line Phase Comparison Relay relay, version 4.9x. This
addendum lists a number of information items that appear in the instruction manual GEK-113209A (revision M2) but are
not included in the current L60 operations.
The following functions/items are not yet available with the current version of the L60 relay:
•N/A
Version 4.0x and higher releases of the L60 relay includes new hardware (CPU and CT/VT modules).
• The new CPU modules are specified with the following order codes: 9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, and 9R.
• The new CT/VT modules are specified with the following order codes: 8F, 8H, 8P.
The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:
The new CT/VT modules can only be used with the new CPUs (9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R), and the old CT/
VT modules can only be used with the old CPU modules (9A, 9C, 9D). To prevent any hardware mismatches, the new
CPU and CT/VT modules have blue labels and a warning sticker stating “Attn.: Ensure CPU and DSP module label
colors are the same!”. In the event that there is a mismatch between the CPU and CT/VT module, the relay will not
function and a DSP ERROR or HARDWARE MISMATCH error will be displayed.

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR
Historically, substation protection, control, and metering functions were performed with electromechanical equipment. This
first generation of equipment was gradually replaced by analog electronic equipment, most of which emulated the single-
function approach of their electromechanical precursors. Both of these technologies required expensive cabling and auxil-
iary equipment to produce functioning systems.
Recently, digital electronic equipment has begun to provide protection, control, and metering functions. Initially, this equip-
ment was either single function or had very limited multi-function capability, and did not significantly reduce the cabling and
auxiliary equipment required. However, recent digital relays have become quite multi-functional, reducing cabling and aux-
iliaries significantly. These devices also transfer data to central control facilities and Human Machine Interfaces using elec-
tronic communications. The functions performed by these products have become so broad that many users now prefer the
term IED (Intelligent Electronic Device).
It is obvious to station designers that the amount of cabling and auxiliary equipment installed in stations can be even further
reduced, to 20% to 70% of the levels common in 1990, to achieve large cost reductions. This requires placing even more
functions within the IEDs.
Users of power equipment are also interested in reducing cost by improving power quality and personnel productivity, and
as always, in increasing system reliability and efficiency. These objectives are realized through software which is used to
perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.
High speed communications are required to meet the data transfer rates required by modern automatic control and moni-
toring systems. In the near future, very high speed communications will be required to perform protection signaling with a
performance target response time for a command signal between two IEDs, from transmission to reception, of less than 3
milliseconds. This has been established by the IEC 61850 standard.
IEDs with the capabilities outlined above will also provide significantly more power system data than is presently available,
enhance operations and maintenance, and permit the use of adaptive system configuration for protection and control sys-
tems. This new generation of equipment must also be easily incorporated into automation systems, at both the station and
enterprise levels. The GE Multilin Universal Relay (UR) has been developed to meet these goals.

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 can communicate over a local area network (LAN) with an operator interface, a programming device, or
another UR device.
Figure 1–2: UR CONCEPT BLOCK DIAGRAM
The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as program-
mable 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.
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.
The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a
dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are con-
nected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilot-
aided 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.
Figure 1–3: UR-SERIES SCAN OPERATION
1.2.3 SOFTWARE ARCHITECTURE
The firmware (software embedded in the relay) is designed in functional modules which 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, Instanta-
neous Overcurrent, Current Differential, Undervoltage, Overvoltage, Underfrequency, and Distance. These objects repre-
sent completely self-contained software modules. The same object-class concept can be used for Metering, Input/Output
Control, HMI, Communications, or any functional entity in the system.
Employing OOD/OOP in the software architecture of the Universal Relay achieves the same features as the hardware
architecture: modularity, scalability, and flexibility. The application software for any Universal Relay (e.g. Feeder Protection,
Transformer Protection, Distance Protection) is constructed by combining objects from the various functionality classes.
This results in a ’common look and feel’ across the entire family of UR-series platform-based applications.
1.2.4 IMPORTANT CONCEPTS
As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understand-
ing 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. An
example of a simple element, and some of the organization of this manual, can be found in the Digital Elements section. 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.

Please refer to Chapter 3: Hardware for detailed mounting and wiring instructions. Review all WARNINGS and CAUTIONS
carefully.
1.4.2 COMMUNICATIONS
The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ether-
net 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 PC COM1 or COM2 port as described
in the CPU Communications Ports section of Chapter 3.
Figure 1–4: RELAY COMMUNICATIONS OPTIONS
To communicate through the L60 rear RS485 port from a PC 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. Refer to the CPU Communications
Ports section in Chapter 3 for option details. The line should be terminated with an R-C network (i.e. 120 Ω, 1 nF) as
described in the Chapter 3.
1.4.3 FACEPLATE DISPLAY
All messages are displayed on a 2 ×20 character vacuum fluorescent display to make them visible under poor lighting con-
ditions. An optional liquid crystal display (LCD) is also available. Messages are displayed in English and do not require the
aid of an instruction manual for deciphering. While the keypad and display are not actively being used, the display will
default to defined messages. Any high priority event driven message will automatically override the default message and
appear on the display.
