469 Quick Reference Guide
Overview
OVERVIEW
This Quick Reference Guide takes you through the installation and setup of your GE Multilin
469 Motor Management Relay, and helps you get setup and running as quickly as possible.
The following topics are covered:
• Installing the 469 relay
• Installing the EnerVista 469 Setup software
• Configuring the 469 relay
This guide contains only basic instructions. For complete information, refer to GE
publication GEK-106474C: 469 Motor Management Relay Instruction Manual.
DESCRIPTION
The 469 Motor Management Relay is a microprocessor-based relay designed for the
protection and management of medium and large horsepower motors and driven
equipment. The 469 is equipped with six (6) output relays for trips, alarms, and start blocks.
Motor protection, fault diagnostics, power metering, and RTU functions are integrated into
one economical drawout package.
Typical applications include: pumps, fans, compressors, mills, shredders, extruders,
debarkers, refiners, cranes, conveyors, chillers, crushers, and blowers. Some of the
protection highlights are detailed here; a complete list is shown below.
Four assignable digital inputs may be configured for a number of different features
including tachometer or generic trip and alarm with a programmable name. The thermal
model incorporates unbalance biasing, RTD feedback, and exponential cooling. In addition
to the 15 standard overload curves, there is a custom curve feature and a curve specifically
designed for the starting of high inertia loads (where the acceleration time exceeds the safe
stall time). A second overload curve is provided for two-speed motors. Ground faults or
earth leakage as low as 0.25 A may be detected using the GE Multilin 50:0.025 ground CT.
CT inputs for phase differential protection are also provided. The 12 RTD inputs provided
may be individually field programmed for different RTD types. Voltage transformer inputs
allow for numerous protection features based on voltage and power quantities. Four 4 to
20 mA analog inputs may be used for tripping and alarming on any transducer input such
as vibration, pressure, flow, etc.
Each relay provides protection, control, and monitoring functions with both local and
remote human interfaces. They also display the present trip/alarm conditions, and
measured system parameters. Recording of past trip, alarm or control events, maximum
demand levels, and energy consumption is also performed.
To aid new users in getting basic protection operating quickly, setpoints are set to typical
default values and advanced features are disabled. These settings can be reprogrammed
at any time.

469 Quick Reference Guide
Mechanical installation
Programming can be accomplished via the front panel. To simplify programming and
provide a more intuitive interface, setpoints can also be entered with a PC running the nocharge EnerVista 469 setup software provided with the relay. Actual values and setpoints
can be displayed, altered, stored, and printed. If settings are stored in a setpoint file, they
can be downloaded at any time to the front panel program port of the relay via a computer
cable connected to the serial port of any personal computer.
MECHANICAL INSTALLATION
Drawout case
The 469 is packaged in the standard SR-series arrangement, which consists of a drawout
relay and a companion case. The case provides mechanical protection for the drawout
portion and is used to make permanent electrical connections to external equipment.
Where required, case connectors are fitted with mechanisms, such as automatic CT
shorting, to allow the safe removal of the relay from an energized panel. There are no
electronic components in the case.
Figure 1: Case Dimensions
Installation
The 469 can be mounted alone or adjacent to another SR-series unit on a standard 19-inch
rack panel. The dimensions of the panel cutout are shown below. When planning the
location of the panel cutout, ensure provision is made for the front door to swing open
without interference to or from adjacent equipment.
469 Quick Reference Guide

Mechanical installation
Figure 2: Single and double unit panel cutouts
Before mounting the 469 in the supporting panel, remove the unit from the case.
From the front of the panel, slide the empty case into the cutout. To ensure the front bezel
sits flush with the panel, apply pressure to the bezel front while bending the retaining tabs
90°. These tabs are located on the sides and bottom of the case and appear as shown
below. After bending all tabs, the case will be securely mounted and the relay can be
inserted. The SR unit is now ready for panel wiring.

Unit withdrawal
Turn off control power before drawing out or reinserting the relay to prevent
maloperation!
CAUTION
CAUTION
If an attempt is made to install a relay into a non-matching case, the case's
configuration pin will prevent full insertion. Applying a strong force in this
instance will result in damage to the relay and case.
To remove the unit from the case:
1. Open the door by pulling from the top or bottom of its right side. It will rotate to the left
about its hinges.
2. Press upward on the locking latch, which is located below the handle, and hold in its
raised position. The tip of a small screwdriver may prove helpful in this operation.
Figure 4: Press latch up and pull handle
3. With the latch raised, pull the center of the handle outward. Once disengaged, continue
rotating the handle up to the stop position.
Figure 5: Rotating handle to stop position

Mechanical installation
4. When the stop position is reached, the locking mechanism will release. The relay will
now slide out of the case when pulled from its handle. To free the relay, it may
sometimes be necessary to adjust the handle position slightly.
Unit insertion
To insert the unit into the case:
1. Ensure that the model number on the left side of the relay matches the requirements of
the installation.
2. Raise the locking handle to the highest position.
3. Hold the unit immediately in front of the case and align the rolling guide pins (near the
hinges of the relay's handle) with the case's guide slots.
4. Slide the unit into the case until the guide pins on the unit have engaged the guide slots
on either side of the case.
5. Once fully inserted, grasp the handle from its center and rotate it down from the raised
position towards the bottom of the relay.
6. Once the unit is fully inserted the latch will be heard to click, locking the handle in the
final position. The unit is mechanically held in the case by the handle rolling pins, which
cannot be fully lowered to the locked position until the electrical connections are
completely mated.
No special ventilation requirements need to be observed during the
installation of the unit. The unit does not require cleaning.

Electrical installation
Get familiarized with the Installation Section of this manual. Make sure that the relay is
properly connected, paying special attention to the following:
Ratings and polarities:
• Control voltage matches the ratings and polarities of the relay power supply. Control
power supplied to the relay must match the installed power supply range. All grounds
must be connected for normal operation regardless of control power supply type. The
label found on the left side of the relay specifies its order code or model number. The
installed power supply's operating range will be one of the following.
LO: 20 to 60 V DC or 20 to 48 V AC
HI: 88 to 300 V DC or 70 to 265 V AC
• The relay ground connections should be connected directly to the ground bus, using the
shortest practical path. A tinned copper, braided, shielding and bonding cable should be
used. As a minimum, 96 strands of number 34 AWG should be used. Belden catalog
number 8660 is suitable.
• Current transformer input ratings and polarities match the secondary ratings of the
corresponding CT. For the correct operation of many relay features, the instrument
transformer polarities shown Figure 7 on page 7 must be followed.
IMPORTANT: The phase and ground current inputs will correctly measure to 20 times
the current input's nominal rating.
• The phase sequence is user programmable to be either ABC or ACB rotation.
• Voltage transformer input ratings match the secondary ratings of the VT. The 469 relays
have four channels for AC voltage inputs, each with an isolating transformer. The nominal
secondary voltage must be in the 50 to 240 V range. The three phase inputs are
designated as the ‘bus voltage’. The Bus VT connections most commonly used, delta (or
open delta), is shown in Figure 7 on page 7. Be aware that these voltage channels are
internally connected as wye. This is why the jumper between the phase B terminal and
the Vcom terminal must be installed with a delta connection.
Digital inputs:
• Digital inputs are connected as indicated below. Ensure correct polarity and do not
connect any logic input circuits to ground or else relay hardware may be damaged.

Accessing setpoints via the front panel
Analog inputs and outputs:
• Analog outputs are connected as indicated in Figure 7 on page 7. Also refer the following
figure. Note that the shield of the cable shall be grounded at one point only, usually at
the PLC/computer end only.
Figure 9: Analog outputs connection
• Analog inputs are connected as indicated in Figure 7 on page 7. Also refer to the figure
below. Note that the shield of the cable shall be grounded at one point only, usually at
the 469 end only.
Figure 10: Analog inputs connection
ACCESSING SETPOINTS VIA THE FRONT PANEL
Refer to the Changing setpoints section in chapter 1 of the 469 Instruction Manual. Note
that to have access to the relay setpoints, you must install a hardware jumper across
terminals C1 and C2 at the back of the relay case. Attempts to enter a new setpoint without
this electrical connection will result in an error message. Important additional information is
provided in the same section regarding passcode, and accessing information via the serial
ports of the relay.

Typical application setup
TYPICAL APPLICATION SETUP
The relay leaves the factory with setpoints programmed to default values, and it is these
values that are shown in all the setpoint message illustrations. Many of these factory
default values can be left unchanged.
At a minimum, the S2 SYSTEM SETUP setpoints must be entered for the system to function
correctly. To safeguard against the installation of a relay whose setpoints have not been
entered, the “Warning, 469 Not Programmed” self-test warning is displayed. In addition, the
5 Block Start relay will be energized, and the “469 In Service” LED will be off. Once the relay
programming is complete, the relay should be in the Service state.
For a typical example on how to set the 469 for motor protection, refer to the Application
Example on page 42. In addition to providing typical wiring diagrams, the example covers
the procedure to set the following features of the 469:
System setup for phase, neutral and ground CTs:
• CT primary ratings
• CT secondary ratings
• CT turn ratio
System setup for VTs:
• VT primary ratings
• VT secondary ratings

WORKING WITH SETPOINT FILES
File support
Opening any EnerVista 469 Setup file will automatically launch the application or provide
focus to the already opened application. If the file was a setpoints file (that is, it has a '469'
extension), which had been removed from the settings list tree menu, it will be added back
to the settings list tree menu.
New files will automatically added to the tree, which is sorted alphabetically with respect to
settings file names.
Setpoints files overview
The EnerVista 469 Setup software interface supports three ways of handling changes to
relay Setpoints:
• In off-line mode (relay disconnected) to create or edit relay setpoints files for later
download to communicating relays.
• Directly modifying while connected to a communicating relay then saving the setpoints
when complete.
• Creating/editing setpoints files while connected to a communicating relay, then saving
the setpoints when complete.
Setpoints files are organized on the basis of file names assigned by the user. A setpoints file
contains data pertaining to the following types of relay setpoints:
• Device definition
• Product setup
• System setup
• Digital inputs
• Output relays
• Protection elements
• Monitoring functions
• Analog inputs and outputs
• Relay testing
• Settings for two speed motors
• User memory map setting tool
Factory default values are supplied and can be restored after any changes.
The EnerVista 469 Setup software displays relay setpoints with the same hierarchy as the
front relay panel display. For specific details on setpoints, refer to chapter 5 of the 469
Instruction Manual.

APPLICATION EXAMPLE
Description
The 469 Motor Management Relay contains many features designed to accommodate a
wide range of motor management applications. This chapter is provided to guide you, the
first time user, through a real-world application.
The following is typical example of how to determine the relay setpoints for a specific
motor that has been applied conservatively. This is only an example and may not address
all issues relating to your specific application. It is recommended that your local protection
engineer determine the setpoints for your motor protective relaying application. Refer to
figures 1 to 3 for schematic diagrams related to this example.
Important points to keep in mind before developing settings for any multifunction
numerical device like the 469 Motor Management relay:
42
469 Quick Reference Guide
Application Example
Gather system data, including, but not limited to:
• CT primary and secondary ratings for all the CTs that will be used to feed the relay
• Motor nameplate data.
• Motor operating curves. The following is a typical set of motor operating curves:
1000.000
Time (sec.)
100.000
10.000
1.000

500
1,000
1,500
Current (Amps)
2,000
2,500
806553A1.CDR
• VT primary and secondary ratings
• System frequency
• System phase sequence
• Define the Protection Elements that will be enabled. Prepare a list of protection functions
including the following information. By default, all the protection functions must be
assumed Disabled:
• Pick-Up parameter
• Operating curve, if applicable
• Time dial or multiplier
• Any additional intentional time delay
• Directionality, if applicable
469 Quick Reference Guide
43
Application Example
• Define how many output contacts will be energized in response to a given protection
function. Note that the 469 relay can be programmed to TRIP or ALARM and, at the same
time, to energize one, a combination, or both auxiliary relays during the process.
• Define if the output relays will be set as failsafe type.
• Define if the 469 will be used to start the motor. If that will be the case, gather
information on the conditions that will be used to execute the command.
• Define if the 469 will be involved in the process of starting the motor, particularly for
reduced voltage start applications.
• Define if the 469 will be applied a multi speed applications.
• Define if the relay will be used to monitor the status of the starter or breaker. It is strongly
recommended that the 469 be always programmed to monitor the status of the
disconnecting device, by means of a dry contact connected to one of the digital inputs of
the relay. Use an auxiliary contact from the breaker or starter either a normally open
contact, 52a, which is normally in open position when the disconnecting device is open,
or a normally closed contact, 52b, which is in close position when the breaker or starter
is open.
• If the relay will be used to respond to digital inputs, prepare a list of them including:
• Logic Input name.
• Condition by which the logic input would be considered asserted.
• Function that the logic input will initiate within the 469.
• If the relay will be used to perform Monitoring functions and act upon certain conditions,
gather information such as:
• Minimum and maximum values
• Alarm and trip values
• Time delays
It is important to familiarize yourself with the relay protection and control functions before
setting up the relay.
To start, simply power on the unit, and follow the instructions in this tutorial. The example
assumes the following system characteristics. It also assumes that relay setpoints are
unaltered from their factory default values.
Refer to the following figures for schematics related to this application example.

The above data will be used to set the output relays to achieve breaker control by setting
digital inputs for breaker status, remote operations, remote status, and alarm indication.
The example assumes that the communications between the station and the Master
Control center will be done by the RTU. Alarms, status indication, and breaker commands
will be hardwired from the relay to the RTU. Similar information could be exchanged
between the RTU and the relay via an RS485 or RS422 Serial Link using Modbus RTU
protocol. Refer to GE Publication GEK-106491: 469 Communications Guide for additional
information.
Instrument Transformer Data
Voltage Transformers:
3 × Delta connected, ratio = 600:120 V
Motor System Voltage = 575 V
Phase CTs:
The phase CT should be chosen such that the FLC is 50% to 100% of CT primary. Since the
FLC is 347.5A a 350:5 or 400:5 CT may be chosen; 400:5 is a standard available size and so
would probably be selected.
Ground CT:
For high resistive grounded systems, sensitive ground detection is possible with the
50:0.025 CT. On solidly grounded or low resistive grounded systems where the fault current
is much higher, a 1A or 5A secondary CT should be used. If residual connection is used,
pickup levels and timers must be set with respect to the acceleration time. The chosen zero
sequence CT needs to be able to handle all potential fault levels without saturating. In this
example, 50:5A CT is selected.
Motor FLC:
Set the Motor Full Load Current to 348A, as specified by the data sheets.
50
469 Quick Reference Guide
Application Example
The above data will be used to set the relay System Parameters, such as CT and VT
connections, VT secondary voltage, and CT and VT primary to secondary ratios.
Motor Protection
Overload Pickup:
The overload pickup is set to the maximum allowed by the service factor of the motor. Since
this motor has RTDs and the relay will be using the RTD bias feature for enhanced
protection. In this case, it would be set to the highest setting of 1.25 x FLC for the motor
service factor of 1.15. If service factor is unknown we must assume 1.0.
Overload Curve:
The standard overload curve to be just below the cold thermal limit to give maximum
process uptime, without compromising protection. The best fitting curve is curve 7.
Short Circuit Trip:
The short circuit trip should be set above the maximum locked rotor current but below the
short circuit current of the fuses. The data sheets indicate a maximum locked rotor current
of 630% FLC or 6.3 x FLC. A setting of 7 x FLC with an instantaneous time delay will be ideal
but nuisance tripping may result due to the asymmetrical starting currents and DC offset. If
asymmetrical starting currents limits the starting capability, set the S/C level higher to a
maximum of 11 x FLC to override this condition (1.7x6.3=11.7 where 1.7 is the maximum DC
offset for an asymmetrical current).
Ground Fault:
Unfortunately, there is not enough information to determine a ground fault setting. These
settings depend on the following information:
1. The Ground Fault current available.
2. System Grounding - For example high resistive grounding, or solidly grounded.
3. Ground Fault CT used.
4. Ground Fault connection, which could be zero sequence or Residual connection.
For the purpose of this example, we will assume a fault current of 10 Amps or 10/50 = 0.2 x
CT, no intentional time delay.
Unbalance Alarm and Trip:
The unbalance settings are determined by examining the motor application and motor
design. The heating effect of unbalance will be protected by enabling unbalance input to
thermal memory; described in details in Chapter 5, Thermal Model. A setting of 10% for the
Unbalance Alarm with a delay of 10 seconds would be appropriate and the trip can be set
to 20% with a delay of 5 seconds.
469 Quick Reference Guide
51
Application Example
Stopped and Running Cool Times:
The motor manufacturer usually supplies this information as either cooling times, or
cooling time constants. In this case they are not part of the data that was given with this
motor. Since RTDs are present and will be wired to the relay, biasing of the thermal model
will be used so it is not critical to have these cooling times from the manufacturer. The
default values of motor cooling time constants are 15 and 30 minutes, and can be used for
the running and stopped cool times respectively. If the manufacturer provides cooling
times instead, the approximate values of the cooling time constants is 1/5 the cooling times
provided by the manufacturer.
Acceleration Trip:
This setpoint should be set higher than the maximum starting time to avoid nuisance
tripping when the voltage is lower or for varying loads during acceleration. If reduced
voltage starting is used, according to the acceleration curves, a setting of 18 seconds would
be appropriate, or if across the line starting is used, a setting of 13 seconds would be
appropriate.
Enable Start Inhibit:
This function will limit starts when the motor is already hot. The relay learns the amount of
thermal capacity used at start. If the motor is hot, thus having some thermal capacity used,
the relay will not allow a start if the available thermal capacity is less than the required
thermal capacity for a start.
Starts/Hour:
Starts/Hour can be set to the # of cold starts as per the data sheet. For this example, it is not
given.
Time Between Starts:
In some cases, the motor manufacturer will specify the time between motor starts. In this
example, this information is not given so this feature can be disabled. However, if the
information is given, the time provided on the motor data sheets should be programmed.
Stator RTDs:
RTD trip level should be set at or below the maximum temperature rating of the insulation.
This example has a class F insulation which has a temperature rating of 155°C, therefore
the Stator RTD Trip level should be set to between 140°C to 155°C, with 155°C being
maximum. The RTD alarm level should be set to a level to provide a warning that the motor
temperature is rising. For this example, 135°C would be appropriate since this motor is
designed for class B rise, 130°C is it's normal hot operating temperature.
Bearing RTDs:
The Bearing RTD alarm and trip settings will be determined by evaluating the temperature
specification from the bearing manufacturer.
52
469 Quick Reference Guide
Application Example
Unbalance Bias Of Thermal Capacity:
Enable the Unbalance Bias of Thermal Capacity so that the heating effect of unbalance
currents is added to the Thermal Capacity Used.
Unbalance Bias K Factor:
The K value is used to calculate the contribution of the negative-sequence current flowing
in the rotor due to unbalance. It is defined as:
R r2
K = -------R r1
(EQ 1)
where: Rr2 = rotor negative-sequence resistance and Rr1 = rotor positive-sequence
resistance.
A formula based on empirical data states that K is equal to 230 divided by the per-unit
locked rotor current squared.
From the data sheet, the locked rotor amps = 631% FLA or 6.31 × FLA. Therefore,
230
230
K = ---------------------------------------------------------------------------- = ----------- ≈ 6
2
6.31
(per-unit locked rotor amps)
(EQ 2)
Hot/Cold Curve Ratio:
The hot/cold curve ratio is calculated by simply dividing the hot safe stall time by the cold
safe stall time or use the motor thermal limits curve. For this example, both are available.
Using the data sheets the, safe stall time H/C or Hot/Cold Curve Ratio is given as 16/18 =
0.89
Enable RTD Biasing:
This will enable the temperature from the Stator RTD sensors, to be included in the
calculations of Thermal Capacity. This model determines the Thermal Capacity Used based
on the temperature of the Stator and is separate from the overload model for calculating
Thermal Capacity Used. RTD biasing is a back up protection element, which accounts for
such things as loss of cooling or unusually high ambient temperature. This measured
temperature is used to bias or modify the thermal capacity value stored in the relay.
RTD Bias Minimum:
Set to 40°C, which is the ambient temperature, obtained from the data sheets.
RTD Bias Mid Point:
The center point temperature is set to the motor's hot running temperature and is
calculated as follows:
Temperature Rise of Stator + Ambient Temperature.
The temperature rise of the stator is 80°C + 10% hot spot allowance, obtained from the data
sheets. Therefore, the RTD Center point temperature is set to 90°C + 40°C or 130°C.
469 Quick Reference Guide
53
Application Example
RTD Bias Maximum:
This setpoint is set to the rating of the insulation or slightly less. A class F insulation is used
in this motor that is rated at 155°C, so setting should be 155.
806550A1.CDR
You should now be familiar with maneuvering through and editing setpoint messages. As
such, we will now limit our discussion to just the values that must be programmed, in order
to meet the requirements of the example application. Any setpoints not explicitly
mentioned should be left at the factory default value.
System Setpoints
The S2 setpoints page contains setpoints for entering the characteristics of the equipment
on the motor electrical system. In our example, these characteristics are specified under
the Power System Data and Instrument Transformer Data headings in the previous subsection. From this information and the resulting calculations, program the page S2
setpoints as indicated.
For current transformers, make the following change in the S2 SYSTEM SETUP Z CURRENT
SENSING setpoints page:
PHASE CT PRIMARY: “400 A”
MOTOR FULL LOAD AMPS FLA: “348 A”
GROUND CT: “5 A Secondary”
54
469 Quick Reference Guide
Application Example
GROUND CT PRIMARY: “50 A”
PHASE DIFFERENTIAL CT: “None”
ENABLE 2-SPEED MOTOR PROTECTION: “No”
For current transformers, make the following change in the S2 SYSTEM SETUP ZV
VOLTAGE SENSING setpoints page:
VT CONNECTION TYPE: “Open Delta”
ENABLE SINGLE VT OPERATION: “Off”
VOLTAGE TRANSFORMER RATIO: “5 : 1”
(for a 600 V system, 600/120 V = 5, where 5 is the VT ratio)
MOTOR NAMEPLATE VOLTAGE: “575 V”
The 469 Motor Management Relay was designed with the ability to display primary system
values. Current and voltage measurements are performed at secondary levels, which the
relay transforms to primary values using CT and VT ratios, system voltage, as well as the
nominal secondary values.
In the case of the phase CTs, configuring the relay for current measurements is simple and
it only requires inputting the CT primary current. Phase CT inputs can be 1 A or 5 A, and
they must be specified when the relay is purchased.
There is more flexibility with regards to Ground CT inputs, as well as VT inputs, where
nominal values are not required ahead of time, before the relay is ordered; therefore more
settings are needed to set the relay for measurements.
Make the following change in the S2 SYSTEM SETUP ZV POWER SYSTEM setpoints page to
reflect the power system:
NOMINAL SYSTEM FREQUENCY: “60 Hz”
SYSTEM PHASE SEQUENCE: “ABC”
The example calls for remote control via serial communications, received from the master
station, through the RTU. Motor starting and stopping is possible via any of the three 469
communication ports.
When a start command is issued, the auxiliary relay assigned for starting control is
activated for 1 second to complete the close coil circuit for a breaker application, or
complete the start control circuit for a contactor application. A contactor sealing contact
would be used to maintain the circuit. For details on issuing a start or stop command via
communications, refer to the GE Publication GEK-106491: 469 Communications Guide.
Make the following changes to the communications settings in the S2 SYSTEM SETUP ZV
SERIAL COMM. CONTROL page.
SERIAL COMMUNICATION CONTROL: “On”
ASSIGN START CONTROL RELAYS: “Auxiliary2”
The Auxiliary 2 relay will be used to start the motor. Note that this auxiliary relay can not be
used for any other application.
469 Quick Reference Guide
55
Application Example
Once the signal is received the motor will be started across the line. Therefore, the following
setpoints are left with their default values. In the S2 SYSTEM SETUP ZV REDUCE VOLTAGE
STARTING setpoints page:
REDUCE VOLTAGE STARTING: “Off”
ASSIGN CONTROL RELAYS: “Auxiliary3” (available for other use)
TRANSITION ON: “Current Only”
ASSIGN TRIP RELAYS: “Trip”
REDUCE VOLTAGE START LEVEL: “100% FLA”
REDUCE VOLTAGE START TIMER: “200 s”
Digital Inputs Setpoints
The S3 setpoints page is for entering the characteristics of the digital inputs. In our example,
these characteristics are specified under the Control System Requirements heading.
Program the S3 setpoints as indicated.
Some of the functions assigned to the digital inputs of the 469 Motor Management Relay
are pre-defined functions, which can be selected from a list. There are four user-defined
functions, called General Switch A to D, associated to the assignable inputs. Set these inputs
to operate output relays, with or without delay, responding to the status change of dry
contacts connected to the digital input terminals. Use the following procedure to set these
functions:
1. Change the default names to meaningful values so they can be easily identified, either
via the LCD or when reviewing event reports.
2. Identify their asserted logic.
3. Define the functionality of the digital inputs.
All the other assignable input functions are pre-defined, and when selected, they can be set
to generate Trip or Alarms, as well as to energize auxiliary outputs as needed.
For breaker position monitoring, set the following pre-defined Digital Input called “Starter
Status”. As per the information provided above, a 52b contact will be used, and must be
connected between terminals D16 to D23:
S3 DIGITAL INPUTS ZV STARTER STATUS Z STARTER STATUS SW: “Starter Auxiliary b”
To set the relay to monitor access to the station, use Assignable Input 1 as “General Switch
A”, as follows. To define the digital input, enter the following data in the S3 DIGITAL INPUTS
ZV ASSIGNABLE INPUT 1 setpoints page.
To identify the digital input:
INPUT 1 FUNCTION: “General Sw. A”
SWITCH NAME: “Stn. Monitor”
To define the asserted logic:
GENERAL SWITCH A: “Normally Open”
To define the functionality:

469 Quick Reference Guide
59
Application Example
There is not information available to set Starts/Hour, Time Between Starts, or the Restart
Block features. Therefore, the following setpoints must be disabled:
JOGGING BLOCK: “Off”
RESTART BLOCK: “Off”
RTD Temperature Setpoints
The S8 RTD Temperature page contains the setpoints for the twelve (12) field programmable
RTDs that are normally used for temperature monitoring. The temperature measured by
each RTD can be compared to pickup values, and set to energize Trip or Alarm outputs.
For proper temperature monitoring, enter the RTD types in the S8 RTD TEMPERTURE Z RTD
TYPES page. Press the MESSAGE T key after each setpoint is completed to move to the next
message.
STATOR RTD TYPE: “100 Ohm Platinum”
BEARING RTD TYPE: “100 Ohm Platinum”
AMBIENT RTD TYPE: “100 Ohm Platinum”
OTHER RTD TYPE: “100 Ohm Platinum” – default value
As per the information provided above, there will be six RTDs, two per phase located in the
Stator, and two Bearing RTDs, one to monitor the ambient temperature.
For Stator Overtemperature protection, enter the following setpoints in the S8 RTD
TEMPERTURE ZV RTD 1 to RTD6 menus:

Undervoltage Protection:
In addition to the settings illustrated above, there will be cases in motor applications where
additional settings will be required, to monitor other system parameters such as voltage
levels.
The following sub-section will illustrate the procedures to set the 469 Motor Management
Relay to meet those requirements.
60
469 Quick Reference Guide
Application Example
Using the same system information, the following example illustrates the steps to set the
469 for Undervoltage protection.
The following setpoints are provided:
Pickup: 70% of nominal voltage – starting
80% of nominal voltage – running
Time Delay: 13.0 s
Other Considerations:
• The function will be active only if there is voltage in the line feeding the motor, to avoid
nuisance trips due to the lack of voltage. The 469 will consider the bus energized only if
the measured voltage is greater than 20% of nominal voltage. A trip condition will be
initiated only if undervoltage is detected in all the phases.
• In order to monitor for VT Fuse Failure or to monitor for undervoltage in one phase only,
set an Alarm when the voltage is 90% of nominal voltage both during start and running.
For the Undervoltage element, enter the following values in the S9 VOLTAGE ELEMENTS
ZV UNDERVOLTAGE setpoints page. Press the ENTER key to save, and then the MESSAGE T
key, after each setpoint is completed, to move to the next message:
U/V ACTIVE ONLY IF BUS ENERGIZED: “Yes”
UNDERVOLTAGE ALARM: “Unlatched”
ASSIGN ALARM RELAYS: “Alarm”
UNDERVOLTAGE ALARM PICKUP: “0.9 x RATED”
STARTING U/V ALARM PICKUP: “0.9 x RATED”
UNDERVOLTAGE ALARM DELAY: “0.0 s”
UNDERVOLTAGE ALARM EVENTS: “Yes”
UNDERVOLTAGE TRIP: “Latched”
UNDRVOLTAGE TRIP MODE: “3-Phase”
ASSIGN TRIP RELAYS: “Trip”
UNDERVOLTAGE TRIP PICKUP: “0.8 x RATED”
STARTING U/V TRIP PICKUP: “0.7 x RATED”
UNDERVOLTAGE TRIP DELAY: “13.0 s”
Installation:
Now that programming for the sample application is complete, the relay should be in the
Service state. Note that the relay is defaulted to the Not Ready state when it leaves the
factory. A minor self-test warning message informs the user that the 469 Motor
Management Relay has not yet been programmed. If this warning is ignored, protection will
be active, using factory default setpoints. The Relay In Service LED Indicator will be on.
By now, once you have completed all the steps illustrated on this typical example, you
should be able to set the GE Multilin 469 Motor Management relay for a typical feeder
application.
