ELECTRICAL INSTALLATION CHAPTER 2: INSTALLATION 2.2.2.2 Thermistor connections Either a positive temperature coefficient (PTC) or negative temperature coefficient (NTC) thermistor may be directly connected to the + and - terminals on the CPU module. By specifying the hot and cold thermistor resistance, the MM300 automatically determines the thermistor type as NTC or PTC. Use thermistors with hot and cold resistance values in the range 100 to 30000 ohms.
CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION 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.

CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION 2.2.3.2 Two CT configuration 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.
ELECTRICAL INSTALLATION CHAPTER 2: INSTALLATION 2.2.3.3 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.
CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION 2.2.3.4 RTD sensor connections (I0_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.
ELECTRICAL INSTALLATION CHAPTER 2: INSTALLATION 2.2.4.
CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION 2.2.4.2 Type IO_D module connections The IO_D module contains four form-C contact output relays. In general, contact outputs can be programmed to follow any one of the digital signals developed by the MM300, such as alarms and status signals.

CONFIGURATION SETPOINTS CHAPTER 6: SETPOINTS 6.2.1.2 Full-voltage non-reversing starter If the Starter Type setpoint is programmed to “FV Non-Reversing”, the pre-contactor relay (if any) is picked up for the set Pre-Contactor Time when a start control is received. When the pre-contactor timer times out, the contactor A relay picks up and seals-in, starting the motor. When a stop control is received, the contactor A relay is dropped out and the motor stops.

High Speed FLA Range: 0.5 to 1000.0 amps in steps of 0.
CHAPTER 6: SETPOINTS CONFIGURATION SETPOINTS Pre-contactor is omitted on forced starts (for example, undervoltage restart immediate or external start). Otherwise, contactor A forced starts operate in the same fashion as other contactor A starts, with the transfer to full voltage occurring when the transfer time expires. Contactor B forced starts are not supervised by this starter transfer timer – any external contactor B starting circuit must itself respect full voltage starting restrictions.
CONFIGURATION SETPOINTS CHAPTER 6: SETPOINTS Forced starts (for example, external start) operate in the same fashion as other starts, with the B contactor not calling for the inverter to ramp until the pre-contactor timer times out. If up-to-speed feedback is not received from the inverter via the contactor B status within the setpoint during a start, a Drive Start Failed alarm is generated.
CHAPTER 6: SETPOINTS CONFIGURATION SETPOINTS Ramp Down Time Range: 0 to 125 seconds in steps of 1 Default: 1second This setpoint specifies the time after signalling the inverter starter to ramp down before the main contactor is opened, cutting power to the starter. If speed feed back is still on when this time expires, a Drive Stop Fail alarm is issued. 6.2.1.7 Soft starter The “Soft Starter” type is used with an external soft starter that ramps the motor speed up on start and down on stop.
CONFIGURATION SETPOINTS CHAPTER 6: SETPOINTS Pre-Contactor Time Range: 0 to 60 seconds in steps of 1 Default: 0 seconds This setpoint specifies the time after a start command before the motor is started. Most starters do not use this delay for forced starts such as external start. This setpoint is also used by the inverter starter and the soft start starter to set the amount of time between powering up an inverter or soft starter and sending the ramp-up command.
CHAPTER 6: SETPOINTS CONFIGURATION SETPOINTS 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. This setpoint is displayed only if the phase CT is selected to 1 A secondary or 5 A secondary.
CONFIGURATION SETPOINTS CHAPTER 6: SETPOINTS 6.2.3 Inputs The MM300 digital (contact) inputs are programmed in this menu. A typical input configuration page is shown below. Figure 11: Input configuration setpoint page Inputs are automatically assigned based on typical wiring diagrams, shown in chapter 2, when a pre-defined starter is selected.
CHAPTER 6: SETPOINTS CONFIGURATION SETPOINTS – “Forward Limit”: This value represents a contact which opens at the forward travel limit. Used by the reversing starter type. – “Hard Wired Permissive”: This value represents an open contact that disables hard-wired control.

CHAPTER 6: SETPOINTS CONFIGURATION SETPOINTS Drive Greasing Inteval Range: 100 to 50000 hours in steps of 100 hours, or OFF Default: OFF Enter the interval at which the motor bearings must be lubricated. When the motor running time exceeds this setpoint, a motor greasing interval alarm is generated. To clear the "Motor Running Hours," use the "Clear Maintenance Timers" command and start the motor. If this feature is not required, set this setpoint to OFF.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS 6.3 Protection elements 6.3.1 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.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS • Ieq represents the equivalent motor heating current in per-unit values on an FLA base. • Iavg represents the average RMS current at each motor terminals in per-unit values on an FLA base. • I2 / I1 represents the negative-sequence to positive-sequence current ratio. • k represents the value of the Unbalance K Factor setpoint, used to adjust the degree of unbalance biasing. The value for k may be estimated as follows.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS The MM300 calculates the steady-state thermal capacity used according to the following equation. TCUSS = Ieq ´ (100% - HCR ) Eq. 3 In the above equation: • TCUSS represents the steady-state thermal capacity used expressed as a percentage. • Ieq represents the equivalent motor heating current in per-unit values on an FLA base. Refer to unbalance biasing for additional details.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS 6.3.1.4 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.

CHAPTER 6: SETPOINTS PROTECTION ELEMENTS Figure 26: Thermal protection configuration setpoints The following setpoints are available for thermal protection. Standard Overload Curve Range: 1 to 15 in steps of 1 Default: 4 This setpoint specifies the standard overload curve to the thermal characteristics of the protected motor. Unbalance K Factor Range: 0 to 19 in steps of 1 Default: 0 This setpoint specifies the degree of unbalance biasing used by the thermal model.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS RTD Bias - Center T Range: 0 to 250°C in steps of 1 or OFF Default: OFF This setpoint specifies the stator RTD temperature appropriate for a thermal capacity used value of 100% – Hot/Cold Ratio. If RTD bias is to be deployed, enter the rated full load motor running temperature. A value of “0” or a value greater than the RTD Bias – Maximum T setpoint disables the RTD bias feature.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS 6.3.2 Mechanical protection Select the Home > Setpoints > Protection > Mech page to edit the mechanical protection setpoints. Figure 27: Mechanical protection configuration setpoints The mechanical protection setpoints are divided into the following categories. • Mechanical jam • Undercurrent protection • Underpower protection • Acceleration protection • Open control circuit trip.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS 6.3.2.2 Undercurrent protection When the motor is in the running state, a trip or alarm will occur should the magnitude Ia, Ib, or Ic fall below the pickup level for the time specified by the Undercurrent Alarm Delay. The pickup levels should be set lower than the lowest motor loading during normal operations. The following setpoints are available for the undercurrent protection element.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS Underpower Trip Level Range: 1 to 100% MNR in steps of 1 or OFF Default: OFF This setpoint specifies the underpower trip pickup level. A value of “OFF” disables the underpower trip function. Underpower Trip Delay Range: 1 to 60 seconds in steps of 1 Default: 1 second The setpoint specifies the amount of time the motor power must meet or exceed the trip pickup level to generate a trip.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS 6.3.3 Electrical protection 6.3.3.1 Current unbalance protection When an unbalance or phase current exceeds the setpoints, an alarm or trip condition is generated.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS NOTE: NOTE The ground fault protection pickup setpoints are entered in %FLA if the Ground CT setpoint is selected as "Residual," or in units of primary amps if a 50:0.025 core balance CT is used and the ground CT is selected as “CBCT 2000:1”. Various situations (for example, contactor bounce) may cause transient ground currents during motor starting that exceed the ground fault pickup levels for a very short period of time.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS 6.3.3.3 Load increase alarm The load increase alarm is used to alarm abnormal load increases that may indicate problems with the process. An alarm is enabled only after the acceleration phase is complete and the motor has entered the running phase, and then only if the current has fallen below the set pickup or one minute has elapsed.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS Undervoltage Trip Delay Range: 1 to 60 seconds in steps of 1 second Default: 30 seconds This setpoint specifies the time that the voltage must be less than or equal to, the undervoltage trip level to generate a trip. 6.3.3.5 Auxiliary undervoltage Undervoltage on the motor supply can present problems for both starting and running the motor.
PROTECTION ELEMENTS CHAPTER 6: SETPOINTS The following setpoints are available for the phase overvoltage element. [Path: Home > Setpoints > Protection > Electrical] Overvoltage Alarm Level Range: 101 to 120% of MNV in steps of 1, or OFF Default: OFF This setpoint specifies the overvoltage alarm pickup level as a percentage of the rated voltage.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS VT Fuse Fail Range: Disabled, Alarm, Trip Default: Trip This setpoint selects the fuse failure action. 6.3.4 Sensor protection 6.3.4.1 RTD protection The MM300 can support up to six 100-R RTDs, each of which may be configured to have a trip temperature and an alarm temperature. The alarm temperature is normally set slightly greater than normal running temperature, and the trip temperature is normally set at the insulation rating.

When the measured temperature is greater than 250°C, the RTD is declared failed and a common RTD open circuit alarm is issued. When the measured temperature is less than -50°C, a common RTD short circuit/low temperature alarm is issued.
CHAPTER 6: SETPOINTS PROTECTION ELEMENTS Cold Resistance Range: 0.1 to 30.0 kOHMS in steps of 0.1 Default: 0.1 kOHMS For a PTC thermistor, enter the resistance that the thermistor must drop below before a Thermistor Trip or Alarm can be cleared. For an NTC thermistor, enter the resistance that the thermistor must rise above before a Thermistor Trip or Alarm can be cleared. Hot Resistance Range: 0.1 to 30.0 kOHMS in steps of 0.1 Default: 5.
CONTROL ELEMENTS CHAPTER 6: SETPOINTS 6.4 Control elements 6.4.1 Starter setpoints Select the Home > Setpoints > Control > Starter page to edit the starter setpoints. Figure 28: Starter configuration setpoints 6.4.1.1 Auto/manual control The auto/manual control element manages the auto/manual control mode, consolidates the start A, start B and stop controls from their various sources, and applies auto/manual, test switch and permissive supervision.
CHAPTER 6: SETPOINTS CONTROL ELEMENTS The auto/manual control element includes non-volatile latches that hold the auto and manual mode states. Besides supervising controls from the sources, the latches drive auto and manual indicators on the MM300 control panel. The latches can be controlled either by an external auto switch contact or by the control panel. • When configured for Auto/Man switch contact, auto is on when the contact is closed energizing the input, and manual is on when the contact is open.
CONTROL ELEMENTS CHAPTER 6: SETPOINTS Hard Wired 2W/3W Range: 2W, 3W Default: 3W The setpoint is for two-wire or three-wire control selection. If in the two-wire mode, all hard-wired start contact inputs being open will be treated as a hard-wired stop control. For reversing and two-speed starter configurations, both start inputs open is treated as a hard-wired stop control. Field Start Ctrl Range: Enabled, Disabled Default: Disabled Sets whether start commands are accepted from field start contact inputs.
CHAPTER 6: SETPOINTS CONTROL ELEMENTS Test Manual Mode Range: On, Off, Unaffected Default: On When the test switch is on, this setpoint determines if the manual mode is forced on, forced off, or is unaffected. 6.4.1.2 Stop/start control element An external stop sequence has occurred if the relay detects that either contactor A or contactor B has dropped out without receiving a stop command.
CONTROL ELEMENTS CHAPTER 6: SETPOINTS If an A or B motor contactor is externally energized, the relay will treat this as a start A or B control, and display an External Start A Alarm or an External Start B Alarm message. The stop/start control element also consolidates the various start and stop signals for the convenience of other elements.
CHAPTER 6: SETPOINTS CONTROL ELEMENTS The starts per hour element defines the number of start attempts allowed in any 60 minute interval. Once the set number of starts has occurred in the last 60 minutes, start controls are inhibited until the oldest start contributing to the inhibit is more than 60 minutes old. The starts per hour element assumes a motor start is occurring when the relay measures the transition of no motor current to some value of motor current.
CONTROL ELEMENTS CHAPTER 6: SETPOINTS Starts/Hour Limit Range: 1 to 5 in steps of 1 or OFF Default: OFF This setpoint specifies the number of starts in the last 60 minutes at which count start control is inhibited. A value of “OFF” defeats this feature. Time Between Starts Range: 1 to 3600 seconds in steps of 1 second, or OFF Default: OFF This setpoint specifies the time following a start before a start control is permitted to prevent restart attempts in quick succession (jogging).
CHAPTER 6: SETPOINTS CONTROL ELEMENTS Figure 30: Process interlock timing Not Started: i.e.: Stopped, Stopping, Tripped, Locked Out, Blocked, Starts Inhibited or Restart In Progress Started i.e.: Pre-contactor, Starting or Running Startup Override == 0, Running Override == OFF Healthy state irrelevant once started Unhealthy starts inhibited Startup Override == 0, Running Override == 0...
CONTROL ELEMENTS CHAPTER 6: SETPOINTS IL A Startup Override Range: 0 to 3600 seconds in steps of 1 Default: 0 seconds This setpoint specifies the time provided for the process interlock switch to reach the healthy state, measured from the moment a start control is received. This includes any pre-contactor time. A value of “0” inhibits starts if the switch state is unhealthy.
CHAPTER 6: SETPOINTS CONTROL ELEMENTS If the motor was not running at the start of the dip, no restart sequence will be initiated. Start controls are ignored while the UVR delay is timing out. While the UVR timer is counting down, the status will change to "UVR Pending". During UVR Pending, any stop or trip will immediately cancel the restart sequence. With control voltage derived from the incoming motor supply, the MM300 will experience the same interruption as the motor.
CONTROL ELEMENTS CHAPTER 6: SETPOINTS UVR Med Dip Time Range: 0.1 to 10.0 s in steps of 0.1 seconds Default: 2.0 s This setpoint represents the maximum duration of medium dips. UVR Long Dip Time Range: 0.5 to 60 min. in steps of 0.5 min., or OFF Default: OFF This setpoint represents the maximum duration of long dips. A value of Off disables restarts after long dips. UVR Med Dip Delay Range: 0.2 to 60.0 seconds in steps of 0.2 seconds Default: 2.0 s This setpoint represents the UV restart medium delay.
CHAPTER 6: SETPOINTS SYSTEM SECURITY 6.5 System security Hardware and passcode security features are designed to restrict user access. This can deter inappropriate employee action and curtail errors. Security against hackers or others with malicious intent should be provided by other means. Security for the external hardwired and field controls should also be externally provided as required. Three security levels above the default level are recognized.
SYSTEM SECURITY CHAPTER 6: SETPOINTS Passcode Level 1, Passcode Level 2, Passcode Level 3 Range: any five-digit number using digits 1 through 5 only or Disabled Default value: 11111 (level 1), 22222 (level 2) Access is granted if a passcode has been correctly entered matching the value of this setpoint. Access Switch Level Range: 1, 2, 3 Default value: 1 Sets the access level provided by the access switch being closed. The contact input for the access switch is configured on the contact inputs page.
