It is recommended that you install a circuit disconnection system for control power, near
the device, which should be easily accessible after installation of the unit. This is in case an
emergency power shut-down of the unit is required.
Figure 2-9: Example of module arrangement
Module and terminal identification
The MM300 input/output and protection modules are labeled with the “IO_” prefix followed
by a one-character identifier as follows.

NOTE:

power supply is used, an appropriate DC voltage source must be used for this power
supply.
.
The full-voltage non-reversing starter type is a full voltage or across-the-line non-reversing
starter.
When a start control is received, the pre-contactor relay (if any) is picked up for the set precontactor time. When the pre-contactor timer times out, relay1 picks up and seals-in,
picking up contactor M, which starts the motor. When a stop control is received, relay1
drops out, contactor M drops out, and the motor stops. The pre-contactor is omitted on
forced starts (for example, UVR Immediate, External Start).
NOTE:
Connect AUX VT to the Control Supply for correct operation of the UV Restart feature and
correct input readings.
RS485 connections
Figure 2-12: Typical RS485 connection
One two-wire RS485 port is provided. Up to 32 MM300 IEDs can be daisy-chained together
on a communication channel without exceeding the driver capability. For larger systems,
additional serial channels must be added. Commercially available repeaters can also be
used to add more than 32 relays on a single channel. Suitable cable should have a
characteristic impedance of 120 ohms and total wire length should not exceed 1200
meters (4000 ft.). Commercially available repeaters will allow for transmission distances
greater than 1200 meters.
Voltage differences between remote ends of the communication link are not uncommon.
For this reason, surge protection devices are internally installed across all RS485 terminals.
Internally, an isolated power supply with an optocoupled data interface is used to prevent
noise coupling.

CAUTION:
To ensure that all devices in a daisy-chain are at the same potential, it is imperative
that the common terminals of each RS485 port are tied together and grounded only
once, at the master or at the MM300. Failure to do so may result in intermittent or
failed communications.
The source computer/PLC/SCADA system should have similar transient protection devices
installed, either internally or externally. Ground the shield at one point only, as shown in
the figure above, to avoid ground loops.
Correct polarity is also essential. The MM300 IEDs must be wired with all the positive (+)
terminals connected together and all the negative (–) terminals connected together. Each
relay must be daisy-chained to the next one. Avoid star or stub connected configurations.
The last device at each end of the daisy-chain should be terminated with a 120 ohm ¼
watt resistor in series with a 1 nF capacitor across the positive and negative terminals.
Observing these guidelines will ensure a reliable communication system immune to
system transients.

Core Balance (Zero Sequence)
The MM300 has three channels for phase current inputs, each with an isolating
transformer. The phase CTs should be chosen so the FLA is not less than 50% of the rated
phase CT primary. Ideally, the phase CT primary should be chosen such that the FLA is
100% of the phase CT primary or slightly less, never more. This will ensure maximum
accuracy for the current measurements. The maximum phase CT primary current is 1000
A.
The ground CT connection can either be a zero sequence (core balance) installation or a
residual connection. Note that only 1 A and 5 A secondary CTs may be used for the
residual connection. The zero sequence connection is shown in the diagram above, and
this is recommended. Unequal saturation of CTs, CT mismatch, size and location of motor,
resistance of the power system, motor core saturation density, etc. may cause false
readings in the residually connected ground fault circuit. Refer to section 2.2.2.1 for CBCT
connection.
Note that if residual ground connection is selected, the CT primary setpoint used by the
Phase CT's will also be used by the residual ground calculations.
CAUTION:
Polarity of the phase CTs is critical for negative-sequence unbalance calculation,
power measurement, and residual ground current detection (if used).
Two CT configurationEach of the two CTs acts as a current source. The current that comes out of the CT on
phase A flows into the interposing CT on the relay marked CT1. From there, the current
sums with the current that is flowing from the CT on phase C which has just passed
MM300 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE11
through the interposing CT on the relay marked CT3. This summed current flows through
the interposing CT marked CT2 and from there, the current splits up to return to its
respective source (CT).
Polarity is very important since the value of phase B must be the negative equivalent of
A
Only one ground connection should be made as shown. If two ground connections are
made, a parallel path for current has been created.
In the two CT configuration, the currents will sum vectorially at the common point of the
two CTs. The diagram illustrates the two possible configurations. If one phase is reading
high by a factor of 1.73 on a system that is known to be balanced, simply reverse the
polarity of the leads at one of the two phase CTs (taking care that the CTs are still tied to
ground at some point). Polarity is important.

NOTE:

Figure 2-14: Two CT connection vector diagram
To illustrate the point further, the following diagram shows how the current in phases A
and C sum up to create phase "B".
Figure 2-15: Two CT connection currents
Once again, if the polarity of one of the phases is out by 180°, the magnitude of the
resulting vector on a balanced system will be out by a factor of 1.73.
On a three-wire supply, this configuration will always work and unbalance will be detected
properly. In the event of a single phase, there will always be a large unbalance present at
the interposing CTs of the relay. If for example phase A was lost, phase A would read zero
while phase B and C would both read the magnitude of phase C. If on the other hand,
phase B was lost, at the supply, phase A would be 180° out-of-phase with phase C and the
vector addition would equal zero at phase B.
Phase voltage inputs (IO_B module)
The MM300 has three channels for AC voltage inputs. There are no internal fuses or ground
connections on the voltage inputs. Polarity is critical for correct power measurement and
voltage phase reversal operation.

Type IO_C module connections
Figure 2-18: Typical wiring for type IO_C module
The IO_C module contains two form-A contact output relays, six digital inputs and control
voltage input.
Contact inputs can be programmed to any of the input functions, such as field stop or
process interlock. The exception is that contactor A status is fixed as the first contact input,
and contactor B status (where used) is fixed as the second contact input.
An AC auxiliary supply must be connected to terminals 12 and 13. This auxiliary voltage
(from slot C only) is also used for actual value indication, for auxiliary undervoltage, and for
undervoltage restart. When three-phase voltages are not available, it is also used to
calculate power quantities and is used as a phase angle reference.
When the IO_C module, located in slot C, senses an interruption to its auxiliary supply, it
raises an AC Low Aux Voltage Inhibit, and forces the input state of the contact inputs to
OFF, as the interruption prevents sensing the actual states.
The two contact outputs can be programmed to follow any one of the digital signals
NOTE:
NOTE:
NOTE:
14MM300 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE
developed by the MM300, such as alarms and status signals. The exception is that the
contactor A relay is fixed as the first contact output, and contactor B relay is fixed as the
second contact output (where used).
Connect AUX VT to the Control Supply for correct operation of the UV Restart feature and
readings of inputs.
All IO_C cards must have the auxiliary input VT wired for proper input sensing. If the
auxiliary voltage on any IO-C module is too low, the contact inputs states for the affected
module will be forced to OFF.

symbol “~” appears in the diagrams above.

Figure 2-20: Typical wiring for type IO_E module
The IO_E module contains two form-A contact output relays, six digital inputs and a
voltage input, which is a required connection. Contact inputs can be programmed to any
of the input functions, such as field stop or process interlock. The exception is that
contactor A status is fixed as the first contact input, and contactor B status (where used) is
fixed as the second contact input.
An AC auxiliary supply must be connected to terminals 12 and 13 of the IO_E module in
slot C. This auxiliary voltage from slot C is used for actual value indication, for auxiliary
undervoltage, and for undervoltage restart. When three-phase voltages are not available,
it is also used to calculate power quantities and is used as a phase angle reference. When
the IO_E module, located in slot C, senses a low auxiliary voltage inhibit and the
Undervoltage restart function is enabled, the states of the contact inputs are forced to OFF.
NOTE:
NOTE:
RTD sensor connections (IO_G module)
16MM300 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE
The auxiliary voltage connection is required on all IO_E modules, both in slot C and in
expansion slots.
The two contact outputs can be programmed to follow any one of the digital signals
developed by the MM300, such as alarms and status signals. The exception is that the
contactor A relay is fixed as the first contact output, and contactor B relay is fixed as the
second contact output (where used).

The MM300 monitors up to six RTD inputs for stator, bearing, ambient, or other
temperature monitoring types. The type of each RTD is 100 ohm platinum (DIN 43760).
RTDs must be three-wire type.
The RTD circuitry compensates for lead resistance, provided that each of the three leads is
the same length. Lead resistance should not exceed 25 ohms per lead. Shielded cable
should be used to prevent noise pickup in industrial environments. RTD cables should be
kept close to grounded metal casings and away from areas of high electromagnetic or
radio interference. RTD leads should not be run adjacent to or in the same conduit as high
current carrying wires.

MM300 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE17
Maintenance
The MM300 requires minimal maintenance. As a microprocessor-based relay, its
characteristics do not change over time. The expected service life of an MM300 is 20 years
when the environment and electrical conditions are within stated specifications.
While the MM300 performs continual self-tests, it is recommended that maintenance be
scheduled with other system maintenance. This maintenance can involve in-service, out-
In-service maintenance
of-service, or unscheduled maintenance.
1.Visual verification of the analog values integrity, such as voltage and current (in
comparison to other devices on the corresponding system).
Page 27
INTERFACING WITH THE MM300CHAPTER 2: INSTALLATION
2.Visual verification of active alarms, relay display messages, and LED indications.
3.Visual inspection for any damage, corrosion, dust, or loose wires.
4.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.
FASTPATH:
To avoid deterioration of electrolytic capacitors, power up units that are stored in a deenergized state once per year, for one hour continuously.
Unscheduled maintenance (system interruption)
•View the event recorder and oscillography for correct operation of inputs, outputs,
and elements.

Introduction to the graphical control panel
The central feature of the graphical control panel is a 3.5-inch 320 by 240 pixel backlit
color LCD screen. The panel also contains keys (pushbuttons) that control the display and
perform commands. In addition, the interface contains START A, START B, and STOP direct
acting control pushbuttons.
The display also contains several LED indicators that provide a summary of the machine
status. Details are displayed on the screen when the user navigates to the appropriate
page.
Figure 2-23: MM300 front panel with example default display
Graphical displayEach display page consists of the three components shown below.
Figure 2-24: Graphical display overview
The header bar (white text on a blue background) displays the hierarchical path name, the
date and time in 24-hour format, and the current password access level. The hierarchical
path is always displayed on the left top side of the graphical display. The present time is
displayed on the right top side. If the test switch is on, the time is replaced with the text

CHAPTER 2: INSTALLATIONINTERFACING WITH THE MM300
•Navigation: soft-keys can be used to traverse across and down the hierarchy of
pages.
•Functional: soft-keys can be used to perform page-specific functions.
•Acknowledgement: soft keys can be used to acknowledge popup windows.
Soft-keys labels change to show relevant selections for the displayed screen. The color of
each soft-key label indicates its functionality. Soft-keys are highlighted for the displayed
page, unauthorized keys are “greyed-out”, and unused keys are not displayed.
The remainder of the screen shows the selected page. Pages are organized in a
hierarchical or tree-based menu structure. To improve readability, some pages are labeled
with rectangular outlines or colored backgrounds. Some pages contain too many fields to
display at once. These pages display arrows bars at the right edge to indicate that the
page continues below the screen. When recalled, scrolled pages are re-positioned at the
top of the page.
Fields display actual value or setting information, and have behaviours that allow help
display, editing, and control.
Each Actual Value analog field displayed on the home page has an associated alarm limit
and changes color to orange when that limit is exceeded. Fields with an associated trip
limit change their color to red when that limit has tripped. Fields that are disabled or
unavailable are greyed-out.
KeypadThe function keys perform the labeled functionality. The summary of function key
operation is shown below.

When the relay is first powered up, the status page lists why the relay is not available for
service. This is not an exhaustive list of setpoints to be configured, but is a list of key items
such as FLA, CT Type, starter type and control Source, that must be configured before the
unit will be available for use. Protection values must still be configured for the motor to be
protected correctly.
Inhibits
These include Process Interlock Stop, and Field Stop.
Trips / Alarms
These trigger depending on the protection setpoints. A typical example would be;
“Overload Trip”.
Information Messages
Information pages are split into two groups
–With navigation (shown above, as an Enter symbol on the right side of the
display)
–Without navigation
When a line showing a message (with navigation) is highlighted, pressing Enter will take
the GCP directly to the page in question, so that the situation can be quickly resolved. A
typical example would be “FLA not set”. Selecting this entry on the page will take you to the
\setpoints\config\motor page.
MM300 programming
techniques
CAUTION:
Basic control panel
To streamline the setting entry process, the graphical control panel omits non-functional
settings from the display.
Settings may be changed while the motor is running. However, appropriate measures
must be taken to limit the consequences of entering unintended or misunderstood
setting values. Consequences of inappropriate settings to the specific application at
hand include loss of protection, loss of control, and undesired starting or stopping.
The MM300 basic control panel provides the basic start and stop panel functionality, as
well as a series of LED indications. The basic control panel is illustrated below.

upgraded since saving the setpoint file, see Upgrading Setpoint Files to a New Revision,
above, for instructions on changing the revision number of a setpoint file.
The following procedure illustrates how to load setpoints from a file. Before loading a
setpoints file, it must first be added to the EnerVista MM300/MM200 Setup
described in the section, Adding Setpoints Files to the Environment.
1.Select the previously saved setpoints file from the File pane of the software main
window.
2.Select the Offline > Edit Settings File Properties menu item and verify that the
corresponding file is fully compatible with the hardware and firmware version of the
target relay. If the versions are not identical, see Upgrading Setpoint Files to a New Revision, above, for details on changing the setpoints file version.
3.Right-click on the selected file and select the Write Settings File to Device item.
4.Select the target relay from the list of devices shown and click Send. If there is an
incompatibility, an "Incompatible Device" error message will occur:

CHAPTER 2: INSTALLATIONUPGRADING RELAY FIRMWARE
NOTE
If there are no incompatibilities between the target device and the settings file, the data
will be transferred to the relay. An indication of the percentage completed will be shown at
the bottom of the main window.
Uninstalling files and clearing data
The unit can be decommissioned by turning off the power to the unit and disconnecting
the wires to it. Files can be cleared after uninstalling the EnerVista software or MM300
device, for example to comply with data security regulations.On the computer, settings
files can be identified by the .m30 extension.
To clear the current settings file do the following:
1.Create a default settings file.
2.Write the default settings file to the relay.
3.Delete all other files with the .m30 extension.
4.Delete any other data files , which can be in standard formats, such as COMTRADE or
.csv.
You cannot directly erase the flash memory, but all records and settings in that memory
can be deleted. Do this using these commands:
DIAGNOSTICS > COMMANDS
•CLEAR LAST TRIP DATA PROMPT
•CLEAR TRIP COUNTERS
•CLEAR MAINTENANCE TIMER
•RESET MOTOR INFORMATION
Upgrading relay firmware
To upgrade the MM300 firmware, follow the procedures listed in this section. Upon
successful completion of this procedure, the MM300
installed with the factory default setpoints.The latest firmware files are available from the
GE Multilin website at
incompatible firmware from being loaded into a MM300 relay.
NOTE:
Before upgrading firmware, it is very important to save the current settings to a file on
your PC. After the firmware has been upgraded, it will be necessary to load this file back
into the MM300 MM300 . Refer to Downloading and Saving Setpoints Files for details on
saving relay setpoints to a file.
NOTE:
All IO_C cards must be connected to aux. voltage during any firmware upgrade procedure.
If aux. voltage is not connected, calibration data from IO_C cards will not be restored
during the upgrade procedure.
Loading new relay firmware
Loading new firmware into the MM300 flash memory is accomplished as follows:
1.Connect the RJ45 port on the relay (labelled "RS485 to Control Panel") to the RS232
port (COM1) on the local PC, using an RS232 (female)-to-RJ45 (male) custom cable (p/n
0804-0180).
MM300 will have new firmware

Common motor
setpoints
Several motor setpoints are dependent on the chosen starter type. The setpoints shown
below are common to all starter types.
Motor Name
Range: up to 20 alphanumeric characters
Default: Motor Name
This setpoint specifies a name for the motor. This name will appear in the actual values,
sequence of events record, and other reports.

Current and voltage transformers
Select the Home > Setpoints > Config > CT-VT page to edit the current and voltage

Figure 4-5: Typical current and voltage transformer setpoints window
The following setpoints are available to configure the current and voltage transformers.
Phase CT Type (Mandatory Setpoint)
Range: None, 1 A Secondary, 5 A Secondary, Direct Connect
Default: Direct Connect
This setpoint specifies the phase CT connection type. The “Direct Connect” value
indicates that no phase CTs are used; instead, motor phase current passes directly
through the relay. The “Direct Connect” selection should never be used where full load
current is greater than 5.0 amps.
NOTE:
If Direct Connect is selected and the FLA is set >5 A, a "FLA too high" message will be
displayed on the Status page.
CT Primary (Mandatory Setpoint)
Range: 5 to 1000 amps in steps of 1
Default: 5 amps
This setpoint specifies the phase CT primary current. It should never be less than the full
load current, and preferably no greater than twice than the full load current.
Standard cut-off default is 20% (0.2pu) of CT primary. At CT primary less then 0.2pu,
primary CT turns are required and an appropriate current cut-off setpoint.
For example: using a 30:1 CT with 6A FLA gives 0.2A CT secondary @ FLA, the cut-off
must be lowered to 0.1A and a minimum of 3 primary turns are required.
NOTE:
This setpoint is displayed only if the phase CT type is set to 1 A secondary or 5 A
secondary.
High Speed CT Primary
Range: 5 to 1000 amps in steps of 1
Default: 5 amps
This setpoint specifies the phase CT primary current when the motor is running at high
speed. It should never be less than the high speed full load current, and preferably no
greater than twice than the high speed full load current.
NOTE:
This setpoint is displayed only if the phase CT type is set to 1 A secondary or 5 A
secondary and the motor starter type is two-speed.
This setpoint specifies the type of ground CT. Select "Residual" if the fourth CT Input on
the IO_A is connected to the residual of the Phase CT. Select 2000:1 if a zero sequence CT
(CBCT) is connected to the ground input on the CPU card.
CT Primary Turns
Range: 1 to 10
Default: 1
For smaller motors where the drawn current is very low, the motor leads may be
wrapped through the CT Primary with several turns thereby increasing the current seen
by the MM300 and as a result increasing the accuracy of the measurement. The value of
this setting should equal the number of turns on the CT Primary to display the correct
current value. Internally the current measurement will be divided by this setting.
Standard cut-off default is 20% (0.2pu) of CT primary. At CT primary less then 0.2pu,
primary CT turns are required and an appropriate current cut-off setpoint.
For example: using a 30:1 CT with 6A FLA gives 0.2A CT secondary @ FLA, the cut-off
must be lowered to 0.1A and a minimum of 3 primary turns are recommended.
Three Phase Voltage Connection
Range: Wye, Delta
Default: Wye
The method in which the IO_B voltage inputs are connected must be entered here. Note
that phase reversal is disabled for single VT operation. All voltages are assumed
balanced.
This setpoint specifies the control transformer connection to the motor supply voltage.
Auxiliary VT Primary
Range: 110 to 690 volts in steps of 1
Default: 415 volts
This setpoint specifies the primary voltage rating of the control transformer.
Auxiliary VT Secondary
Range: 110 to 300 volts in steps of 1
Default: 110 volts
This setpoint specifies the secondary voltage rating of the control transformer.

MM300 Motor Management System
Chapter 5: Protection elements
Thermal protection
Protection elements
The primary protective function of the MM300 is the thermal model. The MM300 integrates
stator and rotor heating into a single model. The rate of motor heating is gauged by
measuring the terminal currents. The present value of the accumulated motor heating is
maintained in the
overload, the motor temperature and thermal capacity used will rise. A trip occurs when
the thermal capacity used reaches 100%. When the motor is stopped and is cooling to
ambient, the thermal capacity used decays to zero. If the motor is running normally, the
motor temperature will eventually stabilize at some steady state temperature, and the
thermal capacity used increases or decreases to some corresponding intermediate value,
which accounts for the reduced amount of thermal capacity left to accommodate
transient overloads.
The thermal model consists of six key elements.
•Unbalance current biasing that accounts for negative-sequence heating.
•Hot/cold biasing that accounts for normal temperature rise.
•RTD biasing that accounts for ambient variation and cooling problems
•An overload curve that accounts for the rapid heating that occurs during stall,
acceleration, and overload.
•Cooling rate that accounts for heat dissipation.
•Thermal protection reset that controls recovery from thermal trips and lockouts.
Each of these categories are described in the following sub-sections.
Overload curve
The overload curve accounts for the rapid motor heating that occurs during stall,
acceleration, and overload. Specifically, the overload curve controls the rate of increase of
Thermal Capacity Used whenever the equivalent motor heating current is greater than
1.01 times the full load current setpoint. The curve is defined by the following equation and
Thermal Capacity Used actual value register. When the motor is in

reflects that overload heating largely swamps the cooling, and this heating is primarily due
to resistive losses in the stator and the rotor windings (said losses being proportional to the
square of the current).
Eq. 1
In the above equation,
•The trip time represents the time (in seconds) for the MM300 to trip, given the motor
starts cold and the current is constant.
•The multiplier represents the value of the Curve Multiplier setpoint. This setpoint can
be used to adjust the curve to match the thermal characteristics of the motor.
•Ieq represents the equivalent motor heating current in per-unit values on a full load
current base. The value of I
is limited in this equation to 8.0 to prevent the overload
eq
from acting as an instantaneous element and responding to short circuits. Equivalent
motor heating current is discussed in the Unbalance biasing section.
For example, a motor with a stall current (also known as locked rotor current) of 8 times its
FLA, with a curve multiplier of 7, if stalled from a cold state, trips in the following amount of
time.
This would respect a safe stall cold time of 10 seconds.
The standard overload curves are displayed below.
