CHAPTER 2: INSTALLATION
NOTE:
NOTE
ELECTRICAL INSTALLATION
The above drawing applies only to a high-voltage power supply. If a low-voltage (DC)
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).
Connect AUX VT to the Control Supply for correct operation of the UV Restart feature and
correct input readings.

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.
MM300 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE

ELECTRICAL INSTALLATION
CHAPTER 2: INSTALLATION
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.
CAUTION:
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.
The uncovered communications cable shield connected to the common terminal should
not exceed 1” (2.5 cm) for proper EMC shielding of the communications cable.

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).
MM300 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE

ELECTRICAL INSTALLATION
Two CT configuration
CHAPTER 2: INSTALLATION
Each 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
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 + C in order for the sum of all the vectors to equate to zero.
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.
Change CT wiring only if the system is de-energized!

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.

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
developed by the MM300, such as alarms and status signals. The exception is that the

RTD sensor connections (IO_G module)
The type IO_G module contains three PT100 RTDs and associated protection functionality.
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.
The uncovered communications cable shield connected to the common terminal should
not exceed 1” (2.5 cm) for proper EMC shielding of the communications cable.

MAINTENANCE
CHAPTER 2: INSTALLATION
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, outof-service, or unscheduled maintenance.
In-service maintenance

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.

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 relay. Refer to Downloading and Saving Setpoints Files for details on saving
relay setpoints to a file.
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).
If there is no RS232 port on your PC:
1.1.
If you are using the MM300 Graphical Control Panel (GCP) or Hand Held
Device (HHD), connect the USB port on the front of the MM300 relay, to the USB
port on the local PC, using a USB 2.0 type A to mini B cable. This configuration
(1) is shown below.
1.2.
If you are using the Basic Control Panel (BCP), and your PC has an RS232 port,
disconnect the existing RJ45 cable from the side of the base unit (labelled
"RS485 to Control Panel"), and connect an RS232-to-RJ45 cable from the PC to
that same RJ45 port on the side of the base unit. This configuration (2) is shown
below.
1.3.
If you are using no control panel, and your PC has an RS232 port, connect an
RS232-to-RJ45 cable from the PC to the RJ45 port on the side of the base unit
(labelled "RS485 to Control Panel"). This configuration (2) is shown below.
Note 1: If your PC does not have an RS232 port, you will have to use a USB-to-serial
converter cable (p/n 0100-0001), available at the GE Online Store (http://
www.gegridsolutions.com). This configuration (3) is shown below.
Note 2: If the unit does not have Graphical Control Panel (GCP), you will have to use a

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.
If Direct Connect is selected and the FLA is set >5 A, a "FLA too high" message will be
displayed on the Status page.
NOTE:
NOTE
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.
This setpoint is displayed only if the phase CT type is set to 1 A secondary or 5 A
secondary.
NOTE:
NOTE
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.
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.

Ground CT Type
Range: None, Residual, CBCT 2000:1
Default: CBCT 2000:1
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.
Auxiliary Voltage Connection (Mandatory Setpoint)
Range: VabVT, VbcVT, VcaVT, VanVT, VbnVT, VcnVT, VanDirect, VbnDirect, VcnDirect
Default: Vab VT
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.

Chapter 5: Protection elements
Protection elements
Thermal protection
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 Thermal Capacity Used actual value register. When the motor is in
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.

CHAPTER 5: PROTECTION ELEMENTS
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
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).
Trip time =
Curve Multiplier ´ 2.2116623
2
0.02530337 x (Pickup - 1) + 0.05054758 x (Pickup -1)
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 Ieq is limited in this equation to 8.0 to prevent the overload
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.
Eq. 2
This would respect a safe stall cold time of 10 seconds.
The standard overload curves are displayed below.
