Role Based Access Control (RBAC)

Efficiently administrate users and roles

within UR devices. The new and advanced

access functions allow users to configure

up to five roles for up to eight configurable

users with independent passwords.

The standard “Remote Authentication

Dial In User Service” (Radius) is used for

authentication.

Event Recorder (Syslog for SEM)

Capture all cyber security related events

within a SOE element (login, logout, invalid

password attempts, remote/local access,

user in session, settings change, FW

update, etc), and then serve and classify

data by security level using standard

Syslog data format. This will enable

integration with established SEM (Security

Event Management) systems.

Fault and Disturbance Recording

The advanced disturbance and event

recording features within the M60 can

significantly reduce the time needed for

postmortem analysis of power system

events and the creation of regulatory

reports. Recording functions include:

• Sequence of Event (SOE)  – 1024 time stamped events

• Oscillography – 64 digital & up to 40 analog channels – Events up to 45s in length

• Data Logger and Disturbance Recording –  16 channels up to 1 sample/cycle/channel

The very high sampling rates and the large

amount of storage space available for

data recording in the M60 can eliminate

the need for installing costly stand-alone

recording equipment.

Advanced Motor Diagnostics

The Multilin M60 provides advanced motor

diagnostics including a broken rotor bar

detection function.  The broken rotor bar

detection is a condition maintenance

function that continuously monitors the

motor’s health while in operation.  The

advanced Motor Current Signature Analysis

(MCSA) continuously analyzes the motor

current signature and based on preset

algorithms, will determine when a broken

rotor bar is present in the motor. With fully

programmable alarms, the broken rotor bar

function will provide early detection of any

rotor problems and advise maintenance

personnel of the impending issue, allowing

for predictive maintenance of the motor and

prevention of catastrophic motor failures.

By providing early indication of potential

rotor problems, serious system issues,

such as reduced starting torque, overloads,

torque and speed oscillation and bearing

wear, can be avoided.  With the advanced

broken rotor bar detection system,

advanced warning of impending problems

reduces catastrophic failures, maximizing

motor life and system uptime.

Advanced Device Health Diagnostics

The M60 performs advanced motor health

diagnostics and records this information

for each of the last 250 consecutive motor

starts.  Analyzing this diagnostic information

for operating parameters that have changed

over these successive starts can indicate

maintenance requirements before damage

occurs and costly repairs are required.

For each motor start, the M60 will provide

a record that contains the following information:

• Date of each motor start

• Motor acceleration time

• Motor starting current

• Motor thermal capacity used during starts

• Average motor load

• Running time after a start

By providing early indication of potential

rotor problems, serious system issues,

such as reduced starting torque, overloads,

torque and speed oscillation and bearing

wear, can be avoided.  With the advanced

broken rotor bar detection system,

advanced warning of impending problems

reduces catastrophic failures, maximizing

motor life and system uptime.

Scalable Hardware

The M60 is available with a multitude

of I/O configurations to suit the most

demanding application needs. The

expandable modular design allows for

easy configuration and future upgrades.

• Multiple CT/VT configurations allow for

the implementation of many protection

schemes, including applications with

high-impedance machine grounding

• RTD inputs allow biasing of the

motor thermal model, as well as

overtemperature protection of the

stator, bearings, and other heat

sensitive components of the motor

• Types of digital outputs include trip

rated Form-A and Solid State Relay

(SSR) mechanically latching, and

Form-C outputs

• DCmA inputs are available to monitor

equipment and process parameters

Monitoring and Metering

The M60 includes high accuracy metering

and recording for all AC signals. Voltage,

current, and power metering are built into

the relay as a standard feature. Current and

voltage parameters are available as total

RMS magnitude, and as fundamental

frequency magnitude and angle.

IEC 61850 Process Bus

The IEC 61850 Process Bus module is

designed to interface with the Multilin

HardFiber System, allowing bi-directional

IEC 61850 fiber optic communications. The

HardFiber System is designed to integrate

seamlessly with existing UR applications,

including protection functions, FlexLogic™,

metering and communications. The Multilin

HardFiber System offers the following benefits:

• Communicates using open standard

IEC 61850 messaging

• Drastically reduces P&C design,

installation and testing labor by

eliminating individual copper terminations

• Integrates with existing M60’s by

replacing traditional CT/VT inputs with

the IEC 61850 Process Bus module

• Does not introduce new cyber security concerns

Advanced Automation

The M60 incorporates advanced automation

features including powerful FlexLogic

programmable logic, communication, and

SCADA capabilities that far surpass what is

found in the average motor protection relay.

The M60 integrates seamlessly with other

UR relays for complete system protection,

including the adjacent motors, feeders and

other balance of plant protection.

FlexLogic

FlexLogic is the powerful UR-platform

programming logic engine that provides

the ability to create customized protection

and control schemes, minimizing the

need and associated costs of auxiliary

components and wiring. Using FlexLogic,

the M60 can be programmed to provide

the required tripping logic along with

custom scheme logic for motor breaker

control (including interlocking with internal

motor start supervision and synchrocheck),

interlocking schemes with adjacent

protections (for example, preventing

sympathetic tripping of healthy feeders),

and dynamic setting group changes.

Two-Speed Motor Protection

The two-speed motor protection feature

allows for the protection of motors that

can operate at two different speeds and

have different full load capacity levels at

each speed. This feature can be used on

motors that have two sets of windings

on each stator, where each set is used to

operate the motor at a different speed.

Underpower Protection

The underpower protection feature

provides for sensitive detection of a

loss of load condition.  The underpower

protection element can be more sensitive

for detecting loss of load conditions

caused by process-related problems than

is possible using a standard undercurrent

element.

Reduced Voltage Starting

The reduced voltage starting feature

provides the controls for signaling the

motor to switch over from a reduced

voltage (that is used during startup) to the

full voltage for motor running operation.

This feature can issue the command

to switch to full operating voltage, by

detecting: a) if the motor load has reached

a preset current level, or b) if a time delay

has elapsed (after starting), or c) both of

these conditions combined.

Under/Over Frequency Protection

The under/over frequency protection element detects when the motor is

operating at off-nominal frequencies (which can damage the process) or signals

to upstream protection or control to implement load-shedding actions.

RTD Protection (Module Option 5C)

The M60 RTD option provides 8 programmable RTD inputs per module that

are used for monitoring the stator, bearing and ambient temperatures. Each RTD input

has 2 operational levels: alarm and trip. The M60 supports RTD trip voting and provides

open RTD failure alarming. Alternatively, a remote RTD module “RRTD”, which

supports 12 RTD inputs, can also be used with the M60 for temperature monitoring.

The RRTD provides cost savings compared with standard RTD wiring.

Start Inhibit

The start inhibit function prevents the starting of a motor when the motor is too

hot and does not have a sufficient amount of thermal capacity available to allow a

start without being tripped offline.

Breaker Failure Protection

The breaker failure protection element monitors for timely operation of the

connected breaker. If a trip command is not successful in operating the breaker

and clearing the fault, the breaker failure element can be used to send trip signals to

upstream breakers to clear the fault.

Undercurrent Protection

The undercurrent protection element provides the ability to trip the motor due

to external conditions that can cause the load being pulled by the motor to drop

below a preset level.  This element is useful when the loss of the load results in a loss

of cooling which will cause the asset to overheat.

Under/Over Frequency Protection

The under/over frequency protection

element detects when the motor is

operating at off-nominal frequencies

(which can damage the process) or signals

to upstream protection or control to

implement load-shedding actions.

RTD Protection (Module Option 5C)

The M60 RTD option provides 8

programmable RTD inputs per module that

are used for monitoring the stator, bearing

and ambient temperatures. Each RTD input

has 2 operational levels: alarm and trip. The

M60 supports RTD trip voting and provides

open RTD failure alarming. Alternatively,

a remote RTD module “RRTD”, which

supports 12 RTD inputs, can also be used

with the M60 for temperature monitoring.

The RRTD provides cost savings compared

with standard RTD wiring.
