The exact placement of a zero-sequence CT to detect only ground fault current is shown
below. If the core balance CT is placed over shielded cable, capacitive coupling of phase
current into the cable shield during motor starts may be detected as ground current unless
the shield wire is also passed through the CT window. Twisted-pair cabling on the zero-
sequence CT is recommended.

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 pre-
contactor time. When the pre-contactor timer times out, relay contact output 1 closes and
seals-in, picking up contactor M, which starts the motor. When a stop control is received,
relay contact output 1 drops out, contactor M drops out, and the motor stops. The pre-
contactor is omitted on forced starts (for example, External Start).

used to add more than 32 relays on a single channel. Suitable cable should have a
characteristic impedance of 120 ohms (for example, Belden #9841) 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
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 MM200. 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 MM200 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.

1.2 Setpoints
1.2.1 Understanding setpoints
Setpoints can be modified via RS485, using the EnerVista MM200 Setup program.
CAUTION
CAUTION: Setpoints may be changed while the motor is running; however it is not recommended
to change important protection parameters without first stopping the motor.
Setpoints will remain stored indefinitely in the internal non-volatile memory even when
control power to the unit is removed. Protection parameters are based on the entered
data. This data must be complete and accurate for the given system for reliable protection
and operation of the motor.
1.2.2 Configuration setpoints
The configuration setpoints contains data on motor configuration as well as system setup,
inputs, outputs, communications, and CTs.
• Motor (setpoints related to motor configuration).
• CT (setpoints related to CT configuration).
• Inputs (setpoints related to digital input configuration)
• Outputs (setpoints related to digital output configuration)
• Comms (setpoints related to communications configuration)
• System (setpoints related to MM200 system configuration, such as the faceplate LEDs)
• Counters (setpoints related to the digital counters)
1.2.2.1 Motor setpoints
The MM200 starter function is responsible for executing the motor startup sequence,
including the pre-contactor start warning. The MM200 provides three pre-defined starters.
• Full-voltage non-reversing
• Full-voltage reversing
• Two-speed
NOTE
NOTE: By selecting a pre-defined starter, inputs and outputs are automatically assigned.
1.2.2.2 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.
Starter Type (Mandatory setpoint)
Range: None, FV Non-Reversing, FV Reversing, Two Speed
Default: FV Non-Reversing
This setpoint selects the starter type. The relay is essentially disabled when the value is
set to “None”. Figure 1 illustrates typical starter timing beginning from the stopped state
for all starter types.

14 MM200 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE
SETPOINTS QUICKSTART GUIDE
Motor FLA (Mandatory setpoint)
Range: 0.5 to 1000.0 amps in steps of 0.1
Default: OFF
This setpoint must be specified for motor protection. The value may be taken from the
motor nameplate data sheets.
Supply Frequency (Mandatory setpoint)
Range: 50 Hz, 60 Hz
Default: 60 Hz
This setpoint specifies the nominal system frequency.
Motor Rating (Mandatory setpoint)
Range: 0.3 to 1100.0 kW in steps of 0.1 or OFF
Default: OFF
This setpoint specifies the motor rating (or low speed motor rating for two-speed
starters) in kWs.
The following sections provide additional information for each starter type.

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
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 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 MM200 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.
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.
NOTE
NOTE: This setpoint is displayed only if the phase CT is selected 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
NOTE: This setpoint is displayed only if the phase CT is selected as 1 A secondary or 5 A
secondary and the motor starter type is two-speed.

16 MM200 MOTOR MANAGEMENT SYSTEM – QUICKSTART GUIDE
PROTECTION ELEMENTS QUICKSTART GUIDE
1.3 Protection elements
1.3.1 Thermal protection
The primary protective function of the MM200 is the thermal model. The MM200 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 four key elements.
• Hot/cold biasing that accounts for normal temperature rise.
• 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.
1.3.1.1 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).
Eq. 1
Eq. 2
In the above equation,
• The trip time represents the time (in seconds) for the MM200 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.
•Iav represents the equivalent motor heating current in per-unit values on a full load
current base. The value of Iav is limited in this equation to 8.0 to prevent the overload
from acting as an instantaneous element and responding to short circuits.
