1.1.1 CAUTIONS AND WARNINGS
Before attempting to install or use the device, review all safety indicators in this document to help prevent injury, equipment
damage, or downtime.
The following safety and equipment symbols are used in this document.
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a hazardous situation which, if not avoided, could result in minor or moderate
injury.
Indicates practices not related to personal injury.
a) GENERAL CAUTIONS AND WARNINGS
The following general safety precautions and warnings apply.
Ensure that all connections to the product are correct so as to avoid accidental risk of shock
and/or fire, for example such as can arise from high voltage connected to low voltage termi-
nals.
Follow the requirements of this manual, including adequate wiring size and type, terminal torque settings, voltage,
current magnitudes applied, and adequate isolation/clearance in external wiring from high to low voltage circuits.
Use the device only for its intended purpose and application.
Ensure that all ground paths are uncompromised for safety purposes during device operation and service.
Ensure that the control power applied to the device, the AC current, and voltage input match the ratings specified
on the relay nameplate. Do not apply current or voltage in excess of the specified limits.
Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety cau-
tions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.
Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage
transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to
attempting work on the device.
Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that
current transformer secondary circuits are shorted out before making or removing any connection to the current
transformer (CT) input terminals of the device.
For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to
such equipment and that trip and close commands to the circuit breakers or other switching apparatus are iso-
lated, unless this is required by the test procedure and is specified by appropriate utility/plant procedure.
When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching
apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are
working on or around this primary equipment to prevent any inadvertent command from this device.
Use an external disconnect to isolate the mains voltage supply.
LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class 1M.
Class 1M devices are considered safe to the unaided eye. Do not view directly with optical
instruments.
This product is rated to Class A emissions levels and is to be used in Utility, Substation Industrial
environments. Not to be used near electronic devices rated for Class B levels.

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.
Figure 1–2: UR 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 are used to
control field devices.
The unit and software 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 are 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 oper-
ands 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 intelligent
electronic devices (IEDs) over dedicated fiber, RS422, or G.703 interface. No switching equipment is required as the IEDs
are connected 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.
1.2.3 SOFTWARE ARCHITECTURE
Firmware is the software embedded in the relay 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 data.” A class is the generalized form of similar objects. By using this approach, 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 com-
pletely 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 B90 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.
