The wiring diagram, above, implements the control strategy inherent in the
independent 3-wire predefined operating mode:
z Logic input I.1 activates a start command and latches logic output O.1.
z Logic input I.4 is the Stop command. A fault response:
z trips logic output O.4, and
z interrupts logic input I.4, thereby disabling the latch, and
z opens logic output I.1

This wiring diagram is intended for use with the example application. For additional

Configuring Parameters

Overview After the wiring connections are made, the next step is to configure parameters.
There are two steps to successful parameter configuration:
1 Enter the operating and protection parameter settings using PowerSuite™ software
running in your PC.
2 Transfer the previously saved configuration file with all parameter settings from
your PC to the LTM R controller.
Because this application example accepts the default factory settings of most
parameters, only a few parameters need to be configured.

Required The following operating and protection parameters must be configured:

Parameters Operating parameters:
Parameter Setting
Motor nominal voltage 400 Vac
Motor full load current 9A

At a Glance

Overview The LTM R controller provides current sensing, metering, and monitoring in support
of the current, temperature and ground fault protection functions. When connected
to an expansion module, the LTM R controller also provides voltage and power
sensing functions. Metering and monitoring can be categorized as follows:
z Measurements: real-time or calculated measurements of current, voltage, or
power provided by analog inputs
z Statistics: protection, diagnostic, motor control, and historical fault and warning
counts stored by the LTM R controller, for analysis of system performance and
maintenance
z System and device faults: faults affecting the LTM R controller’s ability to operate
properly, (internal check, communications, wiring, and configuration errors)
z Motor statistics: historical data describing motor starts and operating time, for
analysis of device operation
z Thermal overload display data: displaying estimates of the time until the next
thermal overload fault and, after a thermal overload fault has occurred, the time
to reset
z System operating status: including the motor state (on, ready, run, fault, warning)
and the time for auto-reset of faults.

Line Currents

Description The LTM R controller measures line currents and provides the value of each phase
in amperes and as a percentage of FLC.

Line Currents The line currents function returns the rms value in amperes of the phase currents
from the 3 CT inputs:
z L1: phase 1 current
z L2: phase 2 current
z L3: phase 3 current
The LTM R controller performs true rms calculations for line currents up to the
7th harmonic.
Single-phase current is measured from L1 and L3.

Ground Current

Description The LTM R controller measures ground currents and provides values in amperes
and as a percentage of FLCmin.
The internal ground current is a measured value and reports 0 when the current falls
below 10% of FLCmin. The external ground current depends on the parameter
settings and reports the calculated value at any current level.

Ground Current The ground current function returns the value of the ground current.
The ground current is either calculated by the LTM R controller from the 3 line
currents measured by the load current transformers (I0Σ) or measured by the
external ground current transformer (I0).

Average Current

Description The LTM R controller calculates average current and provides the value for phase
in amperes and as a percentage of FLC.

Average Current The average current function returns the rms value of the average current.

Average Current The LTM R controller calculates the average current using the measured line
Formulas currents. The measured values are internally summed using the following formula:
Calculated measurement Formula
Average current, three-phase motor Iavg = (L1 + L2 + L3) / 3
Average current, single-phase motor Iavg = (L1 + L3) / 2

Current Phase Imbalance

Description The current phase imbalance function measures the maximum percentage of
deviation between the average current and the individual phase currents.

Formulas The current phase imbalance measurement is based on imbalance ratio calculated
from the following formulas:
Calculated measurement Formula

Thermal Capacity Level

Description The thermal capacity level function calculates the amount of thermal capacity used
and estimates the amount of time remaining until a fault condition is reached (see
p. 111). After a fault, this function estimates the thermal capacity and time required
for the motor to cool calculations (see p. 113). This function uses two thermal
models: one for copper stator and rotor windings of the motor and the other for the
iron frame of the motor. The thermal model with the maximum utilized capacity is
reported.
This function also estimates and displays:
z the time remaining before a thermal overload fault is triggered, and
z the time remaining until the fault condition is cleared–after a thermal overload
fault has been triggered.

Trip Current The Thermal Capacity level function uses one of the following selected trip current
Characteristics characteristics (TCCs):
z definite time
z inverse thermal (default)

Thermal Both copper and iron models use the maximum measured phase current and the
Capacity Models Motor trip class parameter value to generate a non-scaled thermal image. The
reported thermal capacity level is calculated by scaling the thermal image to FLC.

Introducing Fault and Warning Counters

Overview The LTM R controller records the number of faults and warnings that it detects. It
also records the number of times an attempted fault auto-reset was unsuccessful.

Detecting Faults Before the LTM R controller will detect a fault, certain preconditions must exist.
These conditions can include:
z the fault detecting function must be enabled
z a monitored value–for example, current, voltage, or thermal resistance–must rise
above, or fall below, a threshold setting
z the monitored value must remain above or below the threshold setting for a
specified time duration
If all preconditions are satisfied, the LTM R controller detects a fault or warning.

Detecting If a warning detection function is enabled, the LTM R controller detects a warning
Warnings immediately when the monitored value rises above, or falls below, a threshold setting.

Counters When the LTM R controller detects a fault or warning, or when a fault is automatically
reset, the LTM R controller records that fact by incrementing one or more counters.
A counter contains a value from 0 to 65535 and increments by a value of 1 when a
fault, warning or reset event occurs. A counter stops incrementing when it reaches
a value of 65535.
When a fault occurs, the LTM R controller increments at least 2 counters:
z a counter for the specific fault detecting function, and
z a counter for all faults
When a warning occurs, the LTM R controller increments a single counter for all
warnings. However, when the LTM R controller detects a thermal overload warning,
it also increments the thermal overload warnings counter.
When a fault is automatically reset, the LTM R controller increments only the auto-
resets counter.

Clearing All fault and warning counters are reset to 0 by executing the Clear Statistics Command.

All Faults Counter

Description The Faults Count parameter contains the number of faults that have occurred since
the Clear All Statistics Command last executed.
The Faults Count parameter increments by a value of 1 when the LTM R controller
detects any fault.

All Warnings Counter

Description The Warnings Count parameter contains the number of warnings that have occurred
since the Clear All Statistics Command last executed.
The Warnings Count parameter increments by a value of 1 when the LTM R

Auto-Reset Counter

Description The Auto-Reset Count parameter contains the number of times the LTM R controller
attempted–but failed–to auto-reset a fault.
The Auto-Reset Count parameter increments by a value of 1 each time the LTM R
controller unsuccessfully attempts to auto-reset a fault. If an auto-reset attempt is
successful (defined as the same fault not recurring within 60 s), this counter is reset
to zero. If a fault is reset either manually or remotely, the counter is not incremented.
For information on fault management, see p. 254.

Controller Internal Fault

Description The LTM R controller detects and records faults that are internal to the device itself.
Internal faults can be either major or minor. Major and minor faults can change the
state of output relays. Cycling power to the LTM R controller may clear an internal fault.
When an internal fault occurs, the Controller Internal Fault parameter is set.

Major Internal During a major fault, the LTM R controller is unable to reliably execute its own
Faults programming and can only attempt to shut itself down. During a major fault,
communication with the LTM R controller is not possible. Major internal faults include:
z stack overflow fault
z stack underflow fault
z watchdog time out
z ROM checksum failure
z CPU failure
z internal temperature fault (at 100 °C / 212 °F)
z RAM test error

Minor Internal Minor internal faults indicate that the data being provided to the LTM R controller is
Faults unreliable and protection could be compromised. During a minor fault, the LTM R
controller continues to attempt to monitor status and communications, but does not
accept any start commands. During a minor fault condition, the LTM R controller
continues to detect and report major faults, but not additional minor faults. Minor
internal faults include:
z internal network communications failure
z EEPROM error
z A/D out of range error
z Reset button stuck
z internal temperature fault (at 85 °C / 185 °F)
z invalid configuration error (conflicting configuration)
z improper logic function action (for example, attempting to write to a read-only parameter

Controller Internal Temperature

Description The LTM R controller monitors its internal temperature, and reports warning, minor
fault, and major fault conditions. Fault detection cannot be disabled. Warning
detection can be enabled or disabled.
The internal temperature is not cleared when factory default settings are restored
using the Clear All Command, or when statistics are reset using a Clear Statistics
Command.
The controller retains a record of the highest attained internal temperature. For
information about the Controller Internal Temperature Max parameter, see p. 110.

Characteristics The Controller Internal Temperature measured values have the following
characteristics:

Control Command Diagnostic Errors

Description The LTM R controller performs diagnostic tests that detect and monitor the proper
functionality of control commands.
There are four control command diagnostic functions:
z Start Command Check
z Run Check Back
z Stop Command Check
z Stop Check Back

Parameter All four diagnostic functions are enabled as a group. For each function a fault and
Settings warning can be enabled. The configurable parameter settings are:
Parameters Setting range Factory settings
Diagnostic Fault Enable Yes/No No
Diagnostic Warning Enable Yes/No No

Start Command The Start Command Check begins after a Run command, and causes the LTM R
Check controller to monitor the main circuit to ensure that current is flowing. The Start
Command Check:
z reports a Start Command fault or warning, if current is not detected after a delay
of 1 second, or
z ends, if the motor is in Run state and the LTM R controller detects current ≥ 10%
of FLCmin

Run Check Back The Run Check Back begins when the Start Command Check ends. The Run Check
Back causes the LTM R controller to continuously monitor the main circuit to ensure
current is flowing. The Run Check Back:
z reports a Run Check Back fault or warning if average phase current is not
detected for longer than 0.5 seconds without a Stop command, or
z ends, when a Stop command executes

98 1639502 12/2006
 Metering and Monitoring Functions

Stop Command The Stop Command Check begins after a Stop command, and causes the LTM R
Check controller to monitor the main circuit and ensure that no current is flowing.The Stop
Command Check:
z reports a Stop Command fault or warning if current is detected after a delay of 1
second, or
z ends, if the LTM R controller detects current ≤ 5% of FLCmin

Stop Check Back The Stop Check Back begins when the Stop Command Check ends. The Stop
Check Back causes the LTM R controller to continuously monitor the main circuit to
ensure no current is flowing. The Stop Check Back:
z reports a Stop Check Back fault or warning if average phase current is detected
for longer than 0.5 seconds without a Run command, or
z ends, when a Run command executes

it detects incorrect or conflicting external wiring. The LTM R controller can detect the
following 5 wiring errors:
z CT Reversal Error
z Phase Configuration Error
z Motor Temperature Sensor Wiring Error
z Voltage Phase Reversal Error
z Current Phase Reversal Error

Enabling Fault Wiring diagnostics are enabled using the following parameters:

CT Reversal When individual external load CTs are used, they must all be installed in the same
Error direction. The LTM R controller checks the CT wiring and reports an error if it detects
one of the current transformers is wired backwards, when compared to the others.
This function can be enabled and disabled.

Motor When the LTM R controller is configured for motor temperature sensor protection,
Temperature the LTM R controller provides short-circuit and open-circuit detection for the
Sensor Error temperature sensing element.
The LTM R controller signals an error when:
z calculated resistance at the T1 and T2 terminals falls below the fixed short-circuit
tripping threshold, or
z calculated resistance at the T1 and T2 terminals exceeds the fixed open-circuit
tripping threshold
The LTM R controller clears the fault condition when the calculated resistance either
falls below (open-circuit fault) or exceeds (short-circuit fault) a fixed re-closing
threshold. After the fault condition has been cleared, the fault must be reset
according to the configured Reset Mode: manual, automatic or remote.
Short-circuit and open-circuit fault thresholds are factory pre-set, are not
configurable, and have no fault time delay. There are no warnings associated with
the short-circuit and the open-circuit faults.
Short-circuit and open-circuit protection of the motor temperature sensing element
is available for all operating states, for both single-phase and 3-phase motors.
This protection is enabled when a temperature sensor is employed and configured,
and cannot be disabled.
The motor temperature sensor protection function has the following characteristics:

Voltage/Current Both the voltage and current phase reversal function signals a fault when it detects
Phase Reversal that either the voltage or the current phases of a 3-phase motor are out of sequence,
Error indicating a wiring error. Use the Motor Phases Sequence parameter to set the
phase sequence–ABC or ACB–and clear the error.

Note: When the LTM R controller is connected to an expansion module, phase

reversal protection is based on voltage before the motor starts, and on current after
the motor starts.

This protection:
z is active for voltage when:
z the LTM R controller is connected to an expansion module, and
z the LTM R controller is in ready state
z is active for current when the motor is in start state, run state, or fault state
z applies only to 3-phase motors
z has no warning and no timer
This function can be enabled or disabled.

Controller Configuration Checksum

Description To verify that the software configuration has not been accidentally modified, the
LTM R controller re-calculates checksums for the EEROM and FLASH memories.
This check occurs at power-up and periodically thereafter. If the LTM R controller
detects any variation, it reports a Controller Internal Fault.

Metering and Monitoring Functions

Fallback When communication between the LTM R controller and either the network or the
Condition local HMI is lost, the LTM R controller is in a fallback condition. The behavior of logic
outputs O.1 and O.2 following a communication loss is determined by:
z the operating mode (see p. 222), and
z the Network Port Fallback Setting and HMI Port Fallback Setting parameters
Fallback setting selectings can include:
Port Fallback Setting Description
Hold (O.1, O.2) Directs the LTM R controller to hold the state of logic outputs O.1 and
O.2 as of the time of the communication loss.
Run Directs the LTM R controller to perform a Run command for a 2-step
control sequence on the communication loss.
O.1, O.2 Off Directs the LTM R controller to turn off both logic outputs O.1 and O.2
following a communication loss.
O.1, O.2 On Directs the LTM R controller to turn on both logic outputs O.1 and O.2
following a communication loss.
O.1 On Directs the LTM R controller to turn on only logic output O.1
following a communication loss.
O.2 On Directs the LTM R controller to turn on only logic output O.2
following a communication loss.

The following table indicates which fallback options are available for each operating
mode:

Metering and Monitoring Functions

Motor Starts

Description The LTM R controller tracks motor starts and records the data as a statistic that can
be retrieved for operational analysis. The following statistics are tracked:
z Motor Starts Count
z Motor LO1 Starts Count (logic output O.1 starts)
z Motor LO2 Starts Count (logic output O.2 starts)
The Clear Statistics Command resets the Motor Starts Count parameter to 0.

Note: The Motor LO1 Starts Count and Motor LO2 Starts Count parameters cannot
be reset to 0, because these parameters together indicate the usage of the relay
outputs usage over time.

Motor Starts Per Hour

Description The LTM R controller tracks the number of motor starts during the past hour and
records this figure in the Motor Starts Per Hour Count parameter.
The LTM R controller sums starts in 5 minute intervals with an accuracy of 1 interval
(+0/– 5 minutes), which means that the parameter will contain the total number of
starts within either the previous 60 minutes or the previous 55 minutes.
This function is used as a maintenance function to avoid thermal strain on the motor.

Characteristics The motor starts per hour function has the following characteristics:
Characteristic Value
Accuracy 5 minutes (+0/– 5 minutes)
Resolution 5 minutes
Refresh interval 100 ms

Load Sheddings Counter

Description The Load Sheddings Count parameter contains the number of times the load sheddings
protection function has been activated since the last Clear Statistics Command.
For information on the Load Sheddings protection function, see p. 190.

Where:
z H = Hours
z M = Minutes
z S = Seconds

Maximum Internal Controller Temperature

Description The Controller Internal Temperature Max parameter contains the highest internal
temperature–expressed in °C–detected by the LTM R controller’s internal
temperature sensor. The LTM R controller updates this value whenever it detects an
internal temperature greater than the current value.
For information about internal temperature measurement, including the detection of
internal temperature faults and warnings, see p. 96.

Characteristics The Controller Internal Temperature Max parameter has the following
characteristics:

3.6 Thermal Overload Statistics

Time to Trip

Description When a thermal overload condition exists, the LTM R controller reports the time to
trip before the fault occurs in the Time To Trip parameter.
When the LTM R controller is not in a thermal overload condition, to avoid the appearance
of being in a fault state, the LTM R controller reports the time to trip as 9999.
If the motor has an auxiliary fan and the Motor Aux Fan Cooled parameter has been
set, the time to reset is decreased by a factor of 4.

Characteristics The time to trip function has the following characteristics:

3.7 System Operating Status

Overview

Introduction The LTM R controller monitors the motor operating state and the minimum time
required to wait for a:
z reset of a thermal fault
z auto reset delay timeout
z load shed reconnect delay, or
z rapid cycle timer timeout
If more than one timer is active, the parameter displays the maximum timer, which
is the minimum wait for the fault response or the control function to reset.

Access The Motor states can be accessed via:

z rapid cycle
z load shedding
Faults can be assigned to auto-reset groups which have characteristics that control
the time to reset the motor. For more details on the automatic fault reset mode, see
p. 260.
Faults associated with thermal capacity are controlled by the motor characteristics that
affect the time to reset the motor. For more details, see p. 76.
Rapid cycle protects against harm caused by repetitive, successive inrush currents
resulting from too little time between starts. See p. 173 for more details.
Voltage load shedding controls the time to restart the motor following return of voltage
after a load shed event. For more details, see p. 190.

Motor Protection Functions

Predefined The LTM R controller monitors current, ground-current and motor temperature
Functions and sensor parameters. When the LTM R controller is connected to an expansion
Data module, the it also monitors voltage and power parameters. The LTM R controller
uses these parameters in protection functions to detect fault and warning
conditions.The LTM R controller’s response to fault and warning conditions is fixed
for the predefined operating modes. Logic output O.4 activates on a fault, and logic
output O.3 activates on a warning. For more information about pre-defined operating
modes, see p. 222.
You can configure these motor protection functions to detect the existence of
undesirable operating conditions that, if not resolved, can cause motor and
equipment damage.
All motor protection functions include fault detection, and most protection functions
also include warning detection.

Customized In addition to using the protection functions and parameters included in a pre-defined
Functions and operating mode, you can use the Custom Logic Editor in PowerSuite™ software to
Data create a new, customized operating mode. To create a custom operating mode, select
any pre-defined operating mode, then edit its code to meet the needs of your application.
Using the Custom Logic Editor, you can create a customized operating mode by:
z modifying the LTM R controller’s responses to protection faults or warnings
z creating new functions, based on either pre-defined or newly created parameters

Faults A fault is a serious undesirable operating condition. Fault-related parameters can be

configured for most protection functions.
The response of the LTM R controller to a fault include the following:
z output O.4 contacts:
z contact 95-96 is open
z contact 97-98 is closed
z fault LED is On and illuminates a steady red
z fault status bits are set in a fault parameter
z a text message is displayed in an HMI screen (if an HMI is attached)
z a fault status indicator is displayed in the configuration software.
The LTM R controller counts and records the number of faults for each protection function.
After a fault has occurred, merely resolving the underlying condition does not clear the fault.
To clear the fault, the LTM R controller must be reset. See p. 255.

1639502 12/2006 117

Motor Protection Functions

Warnings A warning is a less-serious, though still undesirable, operating condition. A warning

indicates corrective action may be required to prevent a problem condition from
occurring. If left unresolved, a warning may lead to a fault condition. Warning-related
parameters can be configured for most protection functions.
The response of the LTM R controller to a warning include the following:
z output O.3 is closed
z fault LED flashes red 2 times per second
z warning status bits are set in a warning parameter
z a text message is displayed in an HMI screen (if attached)
z a warning status indicator is displayed in the configuration software

Note: For some protection functions, warning detection shares the same threshold
as fault detection. For other protection functions, warning detection has a separate
warning threshold.

The LTM R controller clears the warning whenever the measured value no longer
exceeds the warning threshold—plus or minus a 5% hysteresis band.

Motor Protection Characteristics

Overview The protection functions of the LTM R controller continuously monitor the values of
current parameters. When connected to an expansion module, the LTM R controller
also provides voltage protection and monitors voltage and power parameters.

Operation The following diagram describes the operation of a typical motor protection function.
This diagram, and the following diagrams, are expressed in terms of current.
However, the same principles apply to voltage.

Motor Protection Functions

Settings Some protection functions include configurable settings, including:

z Fault threshold: A limit setting for the monitored parameter that triggers a
protection function fault.
z Warning threshold: A limit setting for the monitored parameter that triggers a
protection function warning.
z Fault timeout: A time delay that must expire before the protection function fault is
triggered. The behavior of a timeout depends on its trip current characteristic profile.
z Trip curve characteristic (TCC): The LTM R controller includes a definite trip
characteristic for all protection functions, except the Thermal Overload Inverse
Thermal protection function, which has both an inverse trip and definite trip curve
characteristic, as described below:
Definite TCC: The duration of the fault timeout remains a constant regardless of
changes in the value of the measured quantity (current), as described in the
following diagram:

 Motor Protection Functions

Inverse TCC: The duration of the time delay varies inversely with the value of the
measured quantity (here, thermal capacity). As the measured quantity increases,
the potential for harm also increases, thereby causing the duration of the time delay
to decrease, as described in the following diagram:

Motor Protection Functions

Hysteresis To improve stability, motor protection functions apply a hysteresis value that is
added to or subtracted from limit threshold settings before a fault or warning
response is reset. The hysteresis value is calculated as a percentage—typically
5%—of the limit threshold and is:
z subtracted from the threshold value for upper limit thresholds
z added to the threshold value for lower limit thresholds.
The following diagram describes the logic result of measurement processing (S)
when hysteresis is applied to an upper limit threshold:

Thermal Overload

Overview The LTM R controller can be configured to provide thermal protection, by selecting
one of the following settings:
z Inverse Thermal (default)
z Definite Time
Each setting represents a Trip Curve Characteristic. The LTM R controller stores the
selected setting in its Thermal Overload Mode parameter. Only one setting can be
activated at a time. See the topics that immediately follow, for information on the
operation and configuration of each setting.
This function applies to both single-phase and 3-phase motors.

Parameter The Thermal Overload function has the following configurable parameter settings,
Settings which apply to every trip current characteristic:
Parameters Setting range Factory setting
Mode z Inverse thermal Inverse thermal
z Definite time

Fault enable Enable/Disable Enable

Warning enable Enable/Disable Enable

Thermal Overload - Inverse Thermal

Description When you set the Thermal Overload Mode parameter to Inverse Thermal and
select a motor trip class, the LTM R controller monitors the motor’s utilized thermal
capacity and signals:
z a warning when utilized thermal capacity exceeds a configured warning threshold.
z a fault when utilized thermal capacity continuously exceeds a calculated fault
threshold, based on the Motor Trip Class setting.

CAUTION
RISK OF MOTOR OVERHEATING
The Motor Trip Class parameter must be set to the thermal heating characteristics
of the motor. Refer to the motor manufacturer’s instructions before setting this
parameter.
Failure to follow this instruction can result in injury or equipment damage.

There is no time delay for the thermal overload warning.

When inverse thermal fault mode is selected, the LTM R controller estimates the:
z Time to Trip: the time until a fault will occur.
z Minimum Wait Time: after a fault has occurred, the time until the LTM R controller
will be automatically reset.
For more information about Time to Trip, see p. 111, and for more information about
Minimum Wait Time see p. 113.
The LTM R controller calculates the Thermal Capacity Level in all operating states.
When power to the LTM R controller is lost, the LTM R controller retains the last
measurements of the motor’s thermal state for a period of 30 minutes, permitting it
to re-calculate the motor’s thermal state when power is re-applied.
Fault and warning monitoring can be separately enabled and disabled.
This function applies to both single-phase and 3-phase motors.

1639502 12/2006 131

Motor Protection Functions

Reset for You can use the Clear Thermal Capacity Level Command—issued from the PLC or
Emergency an HMI—to re-start an overloaded motor in an emergency situation. This command
Restart resets the thermal capacity utilization value to 0 and bypasses the cooling period
required by the thermal model before the motor can be restarted.

WARNING
LOSS OF MOTOR PROTECTION
Clearing the thermal capacity level inhibits thermal protection and can cause
equipment overheating and fire. Continued operation with inhibited thermal
protection should be limited to applications where immediate restart is vital.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.

The Clear Thermal Capacity Level Command will not reset the fault response.
Instead:
z only an action external to the LTM R controller (for example, a reduction in the
motor load) can clear the fault condition
z only a reset command, from the valid reset means configured in the Fault Reset
Mode parameter, will reset the fault response.

WARNING
UNINTENDED EQUIPMENT OPERATION
A reset command may re-start the motor if the LTM R controller is used in a 2-wire
control circuit.
Equipment operation must conform to local and national safety regulations and codes.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.

 Motor Protection Functions

Operation The thermal overload inverse thermal protection function is based on a thermal
model of the motor that combines two thermal images:
z a copper-based image representing the thermal state of the stator and rotor
windings, and
z an iron-based image representing the thermal state of the motor frame
Using measured current and the input motor trip class setting, the LTM R controller
considers only the highest thermal state—iron or copper—when calculating thermal
capacity utilized by the motor, as described below:
θ

θcu
Copper
θfe

1639502 12/2006 133

Motor Protection Functions

When inverse thermal fault mode is selected, the Thermal Capacity Level
parameter–indicating utilized thermal capacity due to load current–is incremented
during both start and run states. When the LTM R controller detects that the thermal
capacity level (q) exceeds the fault threshold (qs), it triggers a thermal overload fault,
as described below:

Starting/Running Fault state - cooling Starting/Running Fault state - cooling

θs

Trip Trip t

Fault and warning monitoring can be separately enabled and disabled. The LTM R
controller will clear a thermal overload fault or warning when the utilized thermal
capacity falls below 95% of the threshold.

Thermal Overload - Definite Time

Description When you set the Thermal Overload Mode parameter to Definite Time, the LTM R
controller signals:
z a warning when measured maximum phase current exceeds a configurable
threshold (OC1 or OC2).
z a fault when the maximum phase current continuously exceeds the same
threshold (OC1 or OC2) for a set time delay.
The thermal overload definite time fault includes a time delay of constant magnitude
- following a start command - before the protection is active and a fault timeout
duration, as described below:
t

Fault - no operation

T2

T1

Is
Is Fault and warning threshold (OC1 or OC2)
T1 Start command
T2 Elapsed time delay
There is no time delay for the thermal overload definite time warning.
Fault and warning monitoring can be separately enabled and disabled.
When the LTM R controller is connected to a 2-speed motor, two thresholds are
used: 1 for low speed (OC1) and 1 for high speed (OC2).
The definite time protection function is disabled following a start by a delay defined
by the Long Start Fault Timeout setting. The LTM R controller, when configured for
overload predefined operating mode, uses the change in state from off to on level
current to begin the Start state. This delay allows the motor to draw current on
startup required to overcome the inertia of the motor at rest.

Current Phase Imbalance

Description The current phase imbalance function signals:

z a warning when the current in any phase differs by more than a set percentage
from the average current in all 3 phases.
z a fault when the current in any phase differs by more than a separately set
percentage from the average current in all 3 phases for a set period of time.

CAUTION
RISK OF MOTOR OVERHEATING
The Current Phase Imbalance Fault Threshold must be properly set to protect the
wiring and motor equipment from harm caused by motor overheating.
z The setting you input must conform to national and local safety regulations and codes.
z Refer to the motor manufacturer’s instructions before setting this parameter.

Failure to follow this instruction can result in injury or equipment damage.

Note: Use this function to detect and guard against smaller current phase
imbalances. For larger imbalances—in excess of 80% of the average current in all
3 phases—use the current phase loss motor protection function.

This function has two adjustable fault time delays:

z one applies to current imbalances occurring while the motor is in start state, and
z one applies to current imbalances occurring after startup while the motor is in run state
Both timers begin if the imbalance is detected in start state.
The function identifies the phase causing a current imbalance. If the maximum
deviation from the 3 phase current average is the same for two phases, the function
identifies both phases.
Fault and warning monitoring can be separately enabled and disabled.
The function applies only to 3-phase motors.

Overview The LTM R controller can be configured to detect ground current:

z internally, by summing the 3-phase current signals from the secondary of the
internal current transformers.
z externally, by measuring the current delivered by the secondary of an external
ground fault current transformer.
Use the Ground Current Mode parameter to select either internal or external ground fault
protection. Only one of these ground current mode settings can be activated at a time.
This function applies to both single-phase and 3-phase motors.

Parameter The ground current protection function has the following configurable parameter
Settings settings, which apply to both internal and external ground current protection:

Internal Ground Current

Description The internal ground current function is enabled when the Ground Current Mode
parameter is set to Internal. When Ground Current Mode is set to External , the
internal ground current function is disabled.

DANGER
IMPROPER FAULT DETECTION
Internal ground current function will not protect people from harm caused by
ground current.
Ground fault thresholds must be set to protect the motor and related equipment.
Ground fault settings must conform to national and local safety regulations and codes.
Failure to follow this instruction will result in death or serious injury.

The internal ground current function sums the current readings from the secondary
of the internal current transformers and signals:
z a warning when the summed current exceeds a set threshold.
z a fault when the summed current continuously exceeds a separately set
threshold for a set period of time.
The internal ground current function has a single fault time delay.
The internal ground current function can be enabled when the motor is in ready
state, start state, or run state. When the LTM R controller is operating in custom
mode, this function can be configured so that it is disabled during start state, and
enabled only during ready state and run state.
Fault and warning monitoring can be separately enabled and disabled.
The function applies to both single-phase and 3-phase motors.

 Motor Protection Functions

Motor Temperature Sensor

Overview The LTM R controller has 2 terminals—T1 and T2—that can be connected to a
motor temperature sensing element to provide protection for motor windings by
detecting high temperature conditions that could lead to damage or degradation.
These protections are activated when the Motor Temp Sensor Type parameter is set
to one of the following settings:
z PTC Binary
z PTC Analog
z NTC Analog
Only one of these motor protection sensing elements can be enabled at a time.

Note: Motor temperature sensor protection is based in ohms. PTC Binary

protection thresholds are pre-set to IEC standards and are non-configurable. PTC
Analog and NTC Analog protection functions may require that you scale the
resistance value to the corresponding threshold level in degrees, based on the
properties of the selected sensing element.

When a sensor type is changed, the LTM R controller’s motor temperature sensing
configuration settings revert to their default values. If a sensor type is replaced with
another sensor of the same type, the setting values are retained.
This function applies to both single-phase and 3-phase motors.

Rapid Cycle Lockout

Description The rapid cycle lockout function prevents potential harm to the motor caused by
repetitive, successive inrush currents resulting from too little time between starts.
The rapid cycle lockout function provides a configurable timer, which begins its
count when the LTM R controller detects On Level Current–defined as 10% of FLC.
At the same time the Rapid Cycle Lockout bit is set.
If the LTM R controller detects a Run command before the rapid cycle lockout has
elapsed, the:
z Rapid Cycle Lockout bit remains set
z LTM R controller ignores the Run command
z HMI (if attached) displays "WAIT"
z LTM R controller Alarm LED flashes red 5 times per second, indicating the LTM R
controller has disabled motor outputs thereby preventing an undesirable
condition caused by starting the motor
z LTM R controller monitors the wait time–if more than 1 timer is active, the LTM R
controller reports the minimum wait time before the longest timer elapses
On power loss, the LTM R controller saves the state of the lockout timer in non-
volatile memory. When the LTM R controller next powers up, the timer restarts its
count and again ignores Run commands until the timer completes the timeout.
Setting the Rapid Cycle Lockout Timeout parameter to 0 disables this function.
The Rapid Cycle Lockout Timeout setting can be edited when the LTM R controller
is in its normal operating state. If an edit is made while the timer is counting, the edit
is effective when the timer finishes counting.
This function has no warning and no fault.

Functional The rapid cycle lockout function includes the following parameters:
Characteristics z 1 time delay:
z Rapid Cycle Lockout Timeout
z 1 status bit:
z Rapid Cycle Lockout

In addition, the Rapid Cycle Lockout function:

Voltage Phase Imbalance

Description The voltage phase imbalance function signals:

z a warning when the voltage in any composed phase differs by more than a set
percentage from the average voltage in all 3 phases
z a fault when the voltage in any composed phase differs by more than a separately
set percentage from the average voltage in all 3 phases for a set period of time

Note: A composed phase is the combined measure of two phases: L1 + L2,

L2 + L3, or L3 + L1.

This function has two adjustable fault time delays:

z one applies to voltage imbalances occurring while the motor is in start state, and
z one applies to voltage imbalances occurring while the motor is in run state, or
when the long start time duration expires
Both timers begin if the imbalance is detected in start state.

Note: Use this function to detect and guard against smaller voltage phase
imbalances. For larger imbalances—in excess of 40% of the average voltage in all
3 phases—use the voltage phase loss motor protection function.

This function is available in start state and run state, when the LTM R controller is
connected to an expansion module.
The function identifies the phase causing a voltage imbalance. If the maximum
deviation from the 3 phase voltage average is the same for two phases, the function
identifies both phases.
Fault and warning monitoring can be separately enabled and disabled.
The function applies only to 3-phase motors.

Voltage Load Shedding

Description The LTM R controller provides voltage load shedding, which you can use to
deactivate non-critical loads if voltage level is substantially reduced. For example,
use voltage load shedding when power is transferred from a main utility supply to a
backup generator system, where the backup generator system can supply power
only to a limited number of critical loads.
With the voltage load shedding function enabled, the LTM R controller monitors the
average phase voltage and:
z reports a load shedding condition and stops the motor when voltage falls below
a configurable load shedding threshold and stays below the threshold for the
duration of a configurable load shedding timer
z clears the load shedding condition when voltage rises above a configurable load
shedding restart threshold and remains above the threshold for the duration of a
configurable load shedding restart timer.
When the LTM R controller clears the load shedding condition:
z in 2-wire (maintained) configuration, it issues a Run command to re-start the motor
z in 3-wire (impulse) configuration, it does not automatically re-start the motor.
If your application includes another device that externally provides voltage load
shedding, the LTM R controller’s load shedding function should not be enabled.
All load shedding thresholds and timers can be adjusted when the LTM R controller
is in its normal operating state. When a load shedding timer is counting at the time
it is adjusted, the new duration time does not become effective until the timer
expires.
This function is available only when your application includes an LTM E expansion module.

Overview Your selection of motor operating mode serves as the primary control function for the
LTM R controller. Select the combination of operating mode and control wiring option
required to start, stop or monitor the state of the motor that the LTM R controller protects.
The topics in this chapter describe the LTM R controller’s:
z operating states, listed below, which determine the objectives of the motor control function:
z energized or de-energized
z configured or not configured
z ready to start a motor
z starting a motor
z running or not running a motor
z warning response
z fault response
z operating modes:
z select from 1 of 10 predefined control programs
z the selected control program monitors inputs, executes commands, and
directs outputs to transition between states according to the specific needs of
common motor starter applications and control sources
z control mode selection, which directs the LTM R controller to respond to
commands that originate from:
- local terminal strip inputs via hard-wired input devices
- local HMI commands via the HMI port
- remote commands from the network via the network port
This chapter also introduces custom operating mode, which you can use to either
tailor a predefined control program or create a new program to meet the needs of
your specific application.

z fault reset mode, which directs the control program to allow fault resets by a
person, a master network controller, or the LTM R control program–depending
upon the type of fault and the authorized control source. Fault reset modes include:
z manual reset: allows resets by a person using a local reset means
z remote reset: adds the ability to reset via commands from the remote master
network controller via the LTM R controller’s network port

Control Modes

Overview The control mode determines which control sources command the LTM R controller
outputs. Control modes include:
Control Mode LTM R controller outputs are commanded by:
Local terminal strip Input devices wired to the input terminals on the front face of the
LTM R controller
Local HMI An HMI device connected to the LTM R controller’s Local HMI port
Network A network PLC connected to the controller network port

Control Mode Control mode is determined by the combination of the:

Selection z state of logic input I.6, and
z Control Local Channel Setting parameter.

When logic input I.6 is: And Control Local Channel Setting is: Control Mode is:
inactive Local terminal strip Local terminal strip
Local HMI Local HMI
active (Not applicable) Network

Note: Regardless of the selected control mode, the LTM R controller will respond
to Stop commands from any local control source.

When logic input I.6 is inactive, the default control mode is Local Terminal Strip.
For a predefined operating mode, only one control source may be enabled to direct
the outputs. You can use the custom logic editor to add one or more additional
control sources.

210 1639502 12/2006

 Motor Control Functions

Local Terminal In Local Terminal Strip control mode, the LTM R controller commands its outputs
Strip according to the state of its inputs. This is the default control mode setting when logic
input I.6 is inactive.
The following conditions apply to Local Terminal Strip control mode:
z Any terminal inputs assigned to start and stop commands control the outputs
according to the motor operating mode.
z When a logic input is active, it sets a bit in the Logic Input number (1 to 6)
parameter for monitoring by the PLC.
z HMI and PLC network start commands are ignored.

Local HMI In Local HMI control mode, the LTM R controller commands its outputs in response
to start and stop commands received from an HMI device connected to the Local
HMI port. via theLocal HMI RJ45 connector on either the LTM R controller or the
expansion module.
The following conditions apply to Local HMI control mode:
z Any HMI start and stop commands control the outputs according to the motor
operating mode.
z All terminal inputs, when active, place bits into the Controller Input number (1 to
6) parameter for monitoring by the PLC.
z Remote network start commands and local terminal start commands are ignored.

Network In Network control mode, a remote PLC sends commands to the LTM R controller
through the network communication port.
The following conditions apply to Network control mode:
z Any network start and stop commands control the outputs according to the motor
operating mode.
z The HMI unit can read (but not write) the LTM R controller parameters.
z All inputs, when active, place bits into the Logic Input number (1 to 6) parameter
for monitoring by the PLC.

1639502 12/2006 211

Motor Control Functions

Bump and Set the Bumpless Transfer Mode parameter to enable bumpless transfer when
Bumpless changing the control mode; clear this parameter to enable bump transfer. The
Control configuration setting for this parameter determines the behavior of logic outputs O.1
Transfers and O.2, as follows:
Bumpless Transfer Mode setting LTM R controller behavior when changing control mode
Bump Logic outputs O.1 and O.2 open (if closed) or remain
open (if already open) until the next valid signal occurs.
The motor stops.
Note: In overload predefined operating mode, logic
outputs O.1 and O.2 are user-defined. The control and
power circuit combine to determine if bumping the
outputs OFF will not stop the motor.
Bumpless Logic outputs O.1 and O.2 are not affected and remain in
their original position until the next valid signal occurs. If
one or more outputs were active and controlling a motor
prior to the transfer, then the motor will not stop as a
consequence of the transfer.

CAUTION
FAILURE TO STOP AND RISK OF UNINTENDED OPERATION
LTM R controller operation cannot be stopped from the terminals when control
mode is changed to Local Terminal Strip control mode if the LTM R controller is:
z operating in Overload operating mode
- and -
z configured for Bumpless transfer of control mode
-and -
z operated over a network using Network control mode
-and -
z operating in Run state
- and -
z configured for 3-wire (impulse) control.

See instructions below.

Failure to follow this instruction can result in injury or equipment damage.

212 1639502 12/2006

 Motor Control Functions

Whenever control mode is changed to Local Terminal Strip control mode, operation
of the LTM R controller cannot be stopped from the terminals because no terminal
input is assigned to a STOP command.
If this behavior is not intended, the control mode must be changed to either Network
control mode or Local HMI control mode to command a STOP. To implement this
change, take one of the following precautionary steps:
z the commissioner should configure the LTM R controller for either bump transfer
of control mode or 2-wire control
z the installer should provide the LTM R controller with a means of interrupting
current to the contactor coil - for example, a push button station wired in series
with the LTM R controller outputs
z the controls engineer should assign a terminal input to disable the Run command
using Custom Configuration Mode assignments.

Fallback The LTM R controller enters a fallback state when communication with the control
Transitions source is lost, and exits the fallback state when communication is restored. The
transition into and out of the fallback state is as follows:
Transition Control source transfer
Entering the fallback state bumpless, when the Control Direct Transition bit is on
Exiting the fallback state determined by the settings for Bumpless Transfer Mode
(bump or bumpless) and Control Direct Transition (on or off)

For a information on how to configure communications fallback parameters, see p. 106.

Operating States

Introduction The LTM R controller responds to the state of the motor and provides control,
monitoring and protection functions appropriate to each of the motor’s operating
states. A motor can have many operating states. Some operating states are
persistent while others are transitional.
A motor’s primary operating states are:
Operating state Description
Ready z The motor is stopped and is not drawing current.
z The LTM R controller:
z detects no fault
z is not performing load shedding
z is not counting down the rapid cycle timer
z is ready to start
Not Ready z The motor is stopped and is not receiving current.
z The LTM R controller:
z detects a fault
z is performing load shedding
z is counting down the rapid cycle timer
Start z The motor begins to receive current.
z The LTM R controller:
z detects that current has reached the On Level Current threshold
z detects that current has not both crossed and re-crossed the
long start fault threshold
z continues to count down the long start fault timer.
Run z The motor continues to receive current.
z The LTM R controller detects that current has both crossed and re-crossed
the long start fault threshold before the LTM R controller fully
counted down the long start fault timer.

Start Cycle

Description The start cycle is the time period allowed for the motor to reach its normal FLC level.
The LTM R controller measures the start cycle in seconds, beginning when it detects
On Level Current—defined as maximum phase current equal to 10% of FLC.
During the start cycle, the LTM R controller compares:
z detected current against the configurable Long Start Fault Threshold parameter,
and
z elapsed start cycle time against the configurable Long Start Fault Timeout parameter.
There are 3 start cycle scenarios, each based on the number of times—0, 1or 2—
maximum phase current crosses the Long Start Fault Threshold. A description of
each scenario is described below.
For information on the statistics the LTM R controller retains describing motor starts,
see p. 65. For information about the long start protection function, see p. 149.

Start Cycle During the start cycle, the LTM R controller transitions through the motor’s operating
Operating States states as follows:
Step Event Operating state
1 LTM R controller receives a start command input signal. Ready
2 The LTM R controller confirms that all startup preconditions Ready
exist (e.g. no faults, load shedding, or rapid cycle timer).
3 The LTM R controller closes the appropriate output contacts Ready
designated as terminals 13-14 or 23-24, thereby closing the
control circuit of the motor starting contactors.
4 The LTM R controller detects that maximum phase current Start
exceeds the On Level Current threshold.
5 The LTM R controller detects that current rises above and then Run
falls below the Long Start Fault Threshold before the Long
Start Fault Timeout timer expires.

5.2 Operating Modes

At a Glance

Summary The LTM R controller can be configured to 1 of 10 predefined operating modes.

Selecting custom operating mode allows you to select one of the 10 predefined
operating modes and tailor it to your specific application, or to create an entirely new
control program.
The selection of a predefined operating mode determines the behavior of all LTM R
controller inputs and outputs.
Each predefined operating mode selection includes a control wiring selection:
z 2-wire (maintained), or
z 3-wire (impulse)

Control Principles

Overview The LTM R controller performs control and monitoring functions for single-phase
and 3-phase electric motors.
z These functions are predefined and fit the applications most frequently used.
They are ready to use and are implemented by simple parameter setting after the
LTM R controller has been commissioned.
z The predefined control and monitoring functions can be adapted for particular
needs using the custom logic editor in PowerSuite™ software to:
z edit protection functions
z change the operation of control and monitoring functions
z alter the default LTM R controller I/O logic

1639502 12/2006 223

Motor Control Functions

Operating The processing of control and monitoring functions has 3 parts:

Principle z acquisition of input data:
z the output of protection function processing
z external logic data from logic inputs
z telecommunication commands (TC) received from the control source
z logic processing by the control or monitoring function
z utilization of the processing results:
z activation of logic outputs
z display of predefined messages
z activation of LEDs
z telecommunication signals (TS) sent via a communications link.

Logic Inputs and The LTM R controller provides 6 logic inputs, 2 logic outputs, 1 warning relay and 1
Outputs fault relay. By adding an expansion module, you can add 4 more logic inputs.
Selecting a predefined operating mode automatically assigns the logic inputs to
functions and defines the relationship between logic inputs and outputs. Using the
custom logic editor, you can change these assignments.

Predefined Operating Modes

Overview The LTM R controller can be configured in 1 of 10 predefined operating modes. Each
operating mode is designed to meet the requirements of a common application configuration.
When you select an operating mode, you specify both the:
z operating mode type, which determines the relationship between logic inputs and
logic outputs, and
z control circuit type, which determines logic input behavior, based on the control
wiring design

Operating Mode There are 5 types of operating modes:

Types
Operating mode type Best used for:
Overload All motor starter applications in which the user defines assignment of:
z logic inputs I.1, I.2, I.3 and I.4
z logic outputs O.1 and O.2
z Aux1, Aux2 and Stop commands from the HMI.

The I/O can be defined using a control program managed by the

master network controller in remote control, by an HMI tool, or by
using custom logic.
Independent Direct-on-line (across-the-line) full-voltage non-reversing motor
starting applications
Reverser Direct-on-line (across-the-line) full-voltage reversing motor
starting applications
Two-Step Reduced voltage starting motor applications, including:
z Wye-Delta
z Open Transition Primary Resistor
z Open Transition Autotransformer

Two-Speed Two-speed motor applications for motor types, including:

z Dahlander (consequent pole)
z Pole Changer

Motor Control Functions

Logic Input When you select an operating mode, you also specify that logic inputs are wired for
Behavior either 2-wire (maintained) or 3-wire (impulse) control. Your selection determines the
valid start and stop commands from the various control sources, and sets the
behavior of the input command following the return of power after an outage:
Control Circuit Type Behavior of logic inputs I.1 and I.2
2-wire (maintained) The LTM R controller, after detecting the rising edge on the input
assigned to start the motor, issues a run command. The run
command remains active only while the input is active. The signal
is not latched.
3-wire (impulse) The LTM R controller:
z after detecting the rising edge on the input assigned to start the
motor, latches the run command, and
z after a stop command, disables the run command to disable
the output relay wired in series with the coil of the contactor
that turns the motor on or off
z following a stop, must detect a rising edge on the input to latch
the run command.

Control logic assignments for logic inputs I.1, I.2, I.3 and I.4 are described in each
of the predefined motor operating modes.

Note: In Network control mode, network commands behave as 2-wire control

commands, regardless of the control circuit type of the selected operating mode.
For information on Control Modes, see p. 210.

226 1639502 12/2006

 Motor Control Functions

In each pre-defined operating mode, logic inputs I.3, I.4, I.5 and I.6 behave as follows:
Logic Input Behavior
I.3 User defined.
I.4 z In 3-wire (impulse) control: a Stop command.
z In 2-wire (maintained) control: a user-defined input that can be
configured to send information to a PLC address over the network.
Note: In Overload operating mode, logic input I.4 is not used and can
be user-defined.
I.5 A Fault Reset command is recognized when this input receives the
rising edge of a signal.
Note: this input must first become inactive, and then receive the rising
edge of a subsequent signal, for another reset to occur.
I.6 Local/Remote control of the LTM R controller’s outputs:
z Active: Remote control by the PLC over the network.
z Inactive: Local control through either the terminal strip or the local HMI
port, as determined by the Control Local Channel Setting parameter.

Logic Output The behavior of logic outputs O.1 and O.2 is determined by the selected operating
Behavior mode. See the topics that follow for a description of the 5 pre-defined operating
mode types and the behavior of logic outputs O.1 and O.2.
When the LTM R controller has lost communication with either the network or the
local HMI, the LTM R controller enters a fallback condition. When it receives a stop
command in a fallback condition, logic outputs O.1 and O.2 behave as follows:
Control Circuit Type Response of logic outputs O.1 and O.2 to a stop command
2-wire (maintained) A stop command overrides the fallback condition and turns off
logic outputs O.1 and O.2 while the stop command is active. After
the stop command is no longer active, logic outputs O.1 and O.2
return to their programmed fallback state.
3-wire (impulse) A stop command overrides the fallback condition and turns off
logic outputs O.1 and O.2. The outputs remain off after the stop
command is removed and do not return to their programmed
fallback state.

For information on configuring fallback-related parameters, see p. 106.

In all operating mode types, the following logic outputs behave as described below:

O.4 Activated by any enabled protection fault:

z Terminals NC 95-96
z Terminals NO 97-98

Control Wiring and Fault Management

Overview When Overload predefined operating mode is selected, the LTM R controller does
not latch logic output commands unless directed by either a PLC master control
program or the LTM R controller’s custom logic program.
For all other predefined operating modes–Independent, Reverser, 2-Step, and 2-Speed–
the predefined control logic in the LTM R controller is designed to meet the the
objectives of many common motor starting applications. This includes managing
motor behavior in response to:
z start and stop actions, and
z fault and reset actions
Because the LTM R controller can be used in special applications–such as fire
pumps that require the motor to run despite a known fault condition–the predefined
control logic is designed so that the control circuit, and not the predefined control
logic, determines how the LTM R controller interrupts current flow to the contactor coil.

Control Logic Predefined control logic acts upon start and stop commands as follows:
Action on Starts z For all 3-wire (impulse) control wiring diagrams, when input 4 is configured as a
and Stops stop command, the LTM R controller must detect input current at logic input I.4 in
order to act on a start command.
z If logic input I.4 is active and a user start action initiates current at logic inputs I.1
or I.2, the LTM R controller detects the rising edge of the current and sets an
internal (firmware) latch command that directs the appropriate relay output to
close and remain closed until the latch command is disabled.
z A stop action that interrupts current at logic input I.4, causes the LTM R controller
to disable the latch command. Disabling the firmware latch causes the output to
open–and remain open–until the next valid start condition.
z For all 2-wire (maintained) control wiring diagrams, the LTM R controller detects
the presence of current at logic inputs I.1 or I.2 as start commands, and the
absence of current disables the start command.

Control Logic Predefined control logic manages faults and reset commands as follows:
Action on Faults z Logic output O.4 opens in response to a fault condition.
and Resets z Logic output O.4 closes in response to a reset command.

1639502 12/2006 229

Motor Control Functions

Control Logic The control circuits, shown in the wiring diagrams in this chapter and in the
and Control Appendix, indicate how the LTM R controller’s control logic and the control circuit
Wiring Together combine to stop a motor in response to a fault:
Managing Faults z For 3-wire (impulse) control circuits, the control strategy links the state of logic
output O.4 to the state of the current at logic input I.4:
z Control logic opens logic output O.4 in response to a fault.
z Logic output O.4 opening interrupts current at logic input I.4, disabling the
control logic latch command on logic output O.1.
z Logic output O.1 opens– due to control logic described above–and stops the
flow of current to the contactor coil.
In order to restart the motor, the fault must be reset and a new start command
must be issued.
z For 2-wire (maintained) control circuits, the control strategy links the state of logic
output O.4 directly with the logic inputs I.1 or I.2.
z Control logic opens logic output O.4 in response to a fault.
z Logic output O.4 opening interrupts current to the logic inputs I.1 or I.2
z Control logic disables the start commands opening logic outputs O.1 or O.2.
In order to restart the motor, the fault must be reset and the state of Start/Stop
operators determines the state of logic inputs I.1 or I.2.
The control circuits needed to run a motor - during a motor protection fault, are not
shown in the wiring diagrams that follow. However, the control strategy is to not link
the state of logic output O.4 to the state of the input commands. In this way, fault
conditions may be annunciated, while control logic continues to manage Start and
Stop commands.

Overload Operating Mode

Description Use Overload operating mode when motor load monitoring is required and motor
load control (start/stop) is performed by a mechanism other than the LTM R controller.

Functional The Overload operating mode includes the following features:

Characteristics z Accessible only in Network control mode.
z Logic output O.4 opens in response to a diagnostic error.
z The LTM R controller sets a bit in a status word when it detects an active signal in:
z logic inputs I.1, I.2, I.3, or I.4, or
z the Aux 1, Aux 2, or Stop buttons on the HMI keypad.
Note: When a bit is set in the input status word, it can be read by a PLC which
can write a bit to the LTM R controller’s command word. When the LTM R controller
detects a bit in its command word, it can turn on the respective output (or outputs).

Note: The LTM R controller does not latch logical output commands unless
directed by a PLC master control program, or a custom logic program.

Two-Speed Operating Mode

Description Use Two-Speed operating mode in two-speed motor applications for motor types
such as:
z Dahlander (consequent pole)
z Pole Changer

Functional This function includes the following features:

Characteristics z Accessible in 3 control modes: Local Terminal Strip, Local HMI, and Network.
z Firmware interlocking prevents simultaneous activation of O.1 (low speed) and
O.2 (high speed) logic outputs.
z Two measures of FLC:
z FLC1 (Motor Full Load Current Ratio) at low speed
z FLC2 (Motor High Speed Full Load Current Ratio) at high speed
z The LTM R controller can change speed in two scenarios:
z The Control Direct Transition bit is Off: requires a Stop command followed by
expiration of the Motor Transition Timeout.
z The Control Direct Transition bit is On: automatically transitions from high
speed to low speed after a time-out of the adjustable Motor Transition
Timeout.
z In local terminal strip control mode, logic input I.1 controls logic output O.1, and
logic input I.2 controls logic output O.2.
z In network or local HMI control modes, when the Motor Run Forward Command
parameter is set to 1 and:
z Motor Low Speed Command is set to 1, logic output O.1 is enabled.
z Motor Low Speed Command is set to 0, logic output O.2 is enabled.
z Logic input I.3 is not used in the control circuit, but can be configured to set a bit
in memory.
z Logic outputs O.1 and O.2 deactivate–and the motor stops–when control voltage
becomes too low.
z Logic outputs O.1, O.2 and O.4 deactivate–and the motor stops– in response to
a diagnostic error.

Note: See Control Wiring and Fault Management, p. 229 for information about the
interaction between:
z the LTM R controller’s predefined control logic, and
z the control wiring, an example of which appears in the following diagrams

Custom Operating Mode

Overview Custom operating mode can be implemented only by using the custom logic editor
in PowerSuite™ software.
To select Custom operating mode, start in the configuration software’s tree control.
Navigate to the Settings → Motor → Motor Operating Mode page and select Custom
as the Operating Mode. This sets the Motor Custom Operating Mode parameter.

Program files Every LTM R controller program consists of two files:

z a configuration file that contains parameter configuration settings
z a logic file that contains a series of logic commands that manage LTM R
controller behavior, including:
z motor start and stop commands
z motor transitions between steps, speeds and directions
z the valid control source and transitions between control sources
z fault and warning logic for relay outputs 1 and 2, and the HMI
z terminal strip reset functions
z PLC and HMI communication loss and fallback
z load shed
z rapid cycle
z starting and stopping LTM R controller diagnostics

When a predefined operating mode is selected, the LTM R controller applies a

predefined logic file that permanently resides in the LTM R controller.
When custom operating mode is selected, the LTM R controller uses a customized
logic file created in the custom logic editor and downloaded to the LTM R controller
from the configuration software.

Transferring files Use the following commands to separately download (from the configuration
software to the LTM R controller) your application’s configuration file and
customized logic file:
To download this file Use this command

Fault Management - Introduction

Overview When the LTM R controller detects a fault condition and activates the appropriate
response, the fault becomes latched. Once a fault becomes latched, it remains latched—
even if the underlying fault condition is eliminated—until cleared by a reset command.
The setting of the Fault Reset Mode parameter determines how the LTM R controller
manages faults. The fault reset mode selections, listed below, are described in the
topics that follow:
z Manual (the default setting)
z Automatic
z Remote
The fault reset mode cannot be changed while a fault remains active. All faults must
be reset before the fault reset mode can be changed.

Fault Reset A Reset command can be issued using any of the following means:
Methods z cycling power
z reset button on the LTM R controller
z reset button on the HMI keypad
z reset command from the HMI engineering tool
z logic input I.5
z a network command
z automatic reset

WARNING
RISK OF UNINTENDED OPERATION
When the LTM R controller is operating in 2-wire control with an active Run
command, a Reset command will immediately restart the motor.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.

1639502 12/2006 255

Motor Control Functions

Fault Specific The LTM R controller’s response to faults depends on the nature of the fault that has
Reset Behaviors occurred and how the related protection function is configured. For example:
z Thermal faults can be reset after the Fault Reset Timeout counts down and the
utilized thermal capacity falls below the Fault Reset Threshold level.
z If the fault includes a reset timeout setting, the timeout must fully count down
before a reset command executes.
z Internal device faults can be reset only by cycling power.
z LTM R controller memory does not retain diagnostic and wiring faults after a
power loss, but does retain all other faults after a power loss.
z Internal, diagnostic, and wiring faults cannot be automatically reset.
z All wiring and diagnostic faults can be manually reset by local reset methods.
z For diagnostic faults, network reset commands are valid only in remote (network)
control mode.
z For wiring faults, network reset commands are not valid in any control mode.

Fault The LTM R controller fault monitoring functions save the status of communications

Manual Reset

Introduction When the Fault Reset Mode parameter is set to Manual, the LTM R controller allows
resets–usually performed by a person–via a power cycle of the control power or by
using a local reset means, including:
z Local Terminal Strip (logic input I.5)
z Reset button on the LTM R controller
z Reset commands from the local HMI
A manual reset provides on-site personnel the opportunity to inspect the equipment
and wiring before performing the reset.

Note: A manual reset blocks all reset commands from the LTM R controller’s
network port—even when the Control Mode is set to Network.

Motor Control Functions

Automatic Reset

Introduction Setting the Fault Reset Mode parameter to Automatic lets you:
z configure the LTM R controller to attempt to reset motor protection and
communications faults without the intervention of either a human operator or the
remote PLC, for example:
z for a non-networked LTM R controller installed at a location that is physically
remote, or locally hard to access
z configure fault handling for each protection fault group in a manner that is
appropriate to the faults in that group:
z set a different timeout delay
z permit a different number of reset attempts
z disable automatic fault resetting

The Control Mode parameter selection determines the available reset methods.
Each protection fault is included in 1 of 3 auto-reset fault groups, based on the
characteristics of that fault, as described below. Each fault group has two
configurable parameters:
z a timeout: the Auto-Reset Group (number 1, 2, or 3) Timeout parameter, and
z a maximum number of permissible fault resets: the Auto-Reset Attempts Group
(number 1, 2, or 3) Setting parameter

WARNING
UNINTENDED EQUIPMENT OPERATION
An auto-reset command may restart the motor if the LTM R controller is used in a
2-wire control circuit.
Equipment operation must conform to local and national safety regulations and codes.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.

260 1639502 12/2006

 Motor Control Functions

Reset Behavior After power is cycled, the LTM R controller clears and sets to 0 the values of the
following parameters:
z Auto-Reset Group number (1, 2, or 3) Timeout and
z Auto Reset Group number (1, 2, or 3) Setting.
On a successful reset, the Number of Resets count is cleared and set to 0. A reset
is successful if, after reset, the motor runs for 1 minute without a fault of a type in the
designated group.

Emergency Use the Clear Thermal Capacity Level Command–in applications where it is
Restart necessary–to clear the Thermal Capacity Level parameter following a Thermal
Overload inverse thermal fault. This command permits an emergency restart before
the motor has actually cooled. It also clears and sets to 0 auto-restart group timeout
and number of auto-resets statistics.

WARNING
LOSS OF MOTOR PROTECTION
Clearing the thermal capacity level inhibits thermal protection and can cause
equipment overheating and fire. Continued operation with inhibited thermal
protection must be limited to applications where immediate restart is vital.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.

Number of Each protection group can be set to manual, 1, 2, 3, 4 or unlimited automatic reset attempts.
Resets Select "0" to disable automatic reset of protection fault groups—and require a manual
reset—even though the Fault Reset Mode parameter is configured for automatic reset.
Select "A" to enable a unlimited auto-reset attempts. After the time delay has expired
the LTM R controller continually attempts to reset every fault in that reset group.

1639502 12/2006 261

Motor Control Functions

Auto-Reset Group 1 faults require a pre-defined cooling time after the monitored parameter
Group 1 returns to and falls below a pre-defined threshold. Group 1 faults include Thermal
Overload and Motor Temp Sensor faults. The cooling time delay is non-configurable.
However, you can:
z add to the cooling time delay by setting the Auto-Reset Group 1 Timeout
parameter to a value greater than 0, or
z disable auto-reset by setting the Auto-Reset Group 1 Timeout parameter to 0
Auto-reset group 1 has the following configurable parameters:
Parameters Setting range Factory setting
Auto-Reset Attempts Group 1 0=manual, 1, 2, 3, 4, A=unlimited A
Setting number of reset attempts
Auto-Reset Group 1 Timeout 0...65535 s 480 s

Auto-Reset Group 2 faults generally do not include a pre-defined cooling time delay before a
Group 2 reset can be executed, but can be reset as soon as the fault condition clears. Many
group 2 faults can result in some motor overheating, depending upon the severity
and duration of the fault condition, which in turn depends upon the protection
function configuration.
You can add a cooling time delay, if appropriate, by setting the Auto-Reset Group 2
Timeout parameter to a value greater than 0. You may also want to limit the number
of reset attempts to prevent premature wear or failure of the equipment.
Auto-reset group 2 has the following configurable parameters:
Parameters Setting range Factory setting
Auto-Reset Attempts Group 2 0=manual, 1, 2, 3, 4, A=unlimited 0
Setting number of reset attempts
Auto-Reset Group 2 Timeout 0...65535 s 1200 s

Auto-Reset Group 3 faults often apply to equipment monitoring and generally do not require a
Group 3 motor cooling period. These faults can be used to detect equipment conditions–for
example, an undercurrent fault that detects the loss of a belt, or an overpower fault
that detects an increased loading condition in a mixer. You may want to configure
group 3 faults in a way that differs significantly from gorups 1 or 2, for example by
setting the number of resets to 0, thereby requiring a manual reset after the
equipment failure has been discovered and corrected.
Auto-reset group 3 has the following configurable parameters:
Parameters Setting range Factory setting
Auto-Reset Attempts Group 3 0=manual, 1, 2, 3, 4, A=unlimited 0
Setting number of reset attempts
Auto-Reset Group 3 Timeout 0...65535 s 60 s

Introduction Setting the Fault Reset Mode parameter to Remote adds resetting faults from the
PLC over the LTM R network port. This provides centralized monitoring and control
of equipment installations. The Control Mode parameter selection determines the

Wiring - General Principles

At a Glance There are six stages in wiring the Controller:

z Wiring the current transformers (see p. 293).
z Wiring the ground fault current transformers (see p. 298).
z Wiring the temperature sensors (see p. 300).
z Wiring the power supply and I/O (see Inputs Wiring and p. 15).
z Wiring the voltage transformers and I/O on the Expansion Module (see Inputs
Wiring and p. 15).
z Wiring the communication port (see p. 306).

Inputs Wiring The controller has 6 digital inputs available via field wiring terminals I.1- I.6. The
input voltage is the same voltage as the controller supply voltage: the controller logic
inputs are internally powered by the control voltage of the controller. Controller
inputs are isolated from the inputs of the expansion module.
The 3 controller terminals for common wiring are not connected to the common of
the LTM R, but are internally connected to the A1 control voltage terminal (see
p. 291).

The 4 digital inputs on the expansion module (I.7 - I.10) are not powered by the
control voltage of the controller. They are externally powered, and the inputs voltage
depends on the expansion module model (24 Vdc, 110 Vac or 220 Vac).

Note: Because the expansion module is powered by the controller, it doesn’t have
a separate control voltage.

For more information on input characteristics, see p. 38.

Wiring - Current Transformers (CTs)

Overview The LTM R controller has 3 CT windows through which you can route motor leads
to contactor load connections.
The CT windows enable you to wire the controller in four different ways, depending
on the voltage and controller model used:
z Internal CT wiring through the windows.
z Internal CT wiring using multiple passes.
z Internal CT wiring using the lug kit (ref. Class 9999 MLPL).
z External Load CT wiring.
This section describes each of these options.

Internal CT Typical wiring using the CT windows for either three-phase or single-phase motors:
Wiring through
the Windows
3 1

L1 L2 L3 L N

1639502 12/2006 293

Installation

Internal CT The controller will physically support up to a maximum of 5 passes of 2.5 mm2 (14 AWG)
Wiring Using wire through the CT windows. There are three looping windows located under the
Multiple Passes CT windows that physically support up to a maximum of 4 wire loops.
You can set the parameter Load CT Multiple Passes to account for the number of
times the motor wires pass through the CT window in order to display the correct
current readings. For more information, see p. 47.
Typical wiring using 2 passes (1 wire loop):
3

L1 L2 L3

Multiply the current by the number of times that the motor wires pass through the CT windows
to determine the amount of current passing through the internal current sensors.
You may add multiple passes for one of the following reasons:
z To increase the current sensed by the internal current sensors to a level that the
controller can properly detect
z To provide a more accurate reading by the internal current sensors

294 1639502 12/2006

 Installation

We recommend that you select a controller with an FLC value range that includes
the motor FLC. However, if the motor FLC is less than the FLC range of the
controller, multiple passes can increase the current level sensed by the internal
current sensors to one that the controller can detect. For example, if you use a
controller with an FLC range of 5 to 100 A, and the motor FLC is 3 A, the controller
cannot properly sense the current. In this case, if you pass the power wiring through
the internal current sensors of the controller 2 times, the internal current sensors of
the controller sense 6 A (2 passes x 3 A), a current level that falls within the FLC
range of the controller.
For more information about controller types, see p. 15.

1639502 12/2006 295

Internal CT The controller accepts the Class 9999 Type MLPL lug-lug kit.

Note: The lug-lug kit is IP0.

For more information on the lug-lug kit, refer to instruction bulletin 30072-013-101
supplied with the kit or available from www.us.SquareD.com (under Technical Library).

296 1639502 12/2006

 Installation

External Load CT The controller can accept 5A and 1A secondary signals from external current transformers.
Wiring The recommended controller model for these currents is the 0.4-8A model. You can also
use multiple passes through the controller CT windows, if required.
External CTs are specified with a transformation ratio. The ratio of the external CT
is the ratio of the motor input current to the CT output current.
Set the parameters Load CT Primary (the first number of the CT ratio), Load CT
Secondary (the second number of the CT ratio), and Load CT Multiple Passes (the
number of times the CT output wires pass through the controller’s internal CT windows)
to enable the controller to adjust the FLC range and display the actual line current.
For more information, see p. 47.
Typical wiring using external CTs:
3

L1 L2 L3

Note: The controller measures current at 47-63 Hz fundamental frequency. Therefore, if

the controller is used with a variable speed drive, the controller must be installed between
the drive and the line. The CTs cannot be used between the drive outputs and the motor
since the drive can output fundamental frequencies outside the 47-63 Hz range.

For a description of external CT characteristics, see p. 15.

1639502 12/2006 297

Installation

Wiring - Ground Fault Current Transformers

Ground Fault The LTM R controller has 2 terminals that can be connected to an external ground
Current fault current transformer (GFCT): Z1 and Z2.
Transformer The following diagram shows typical wiring using a GFCT:
Wiring 3

L1 L2 L3

Note: You must wire the ground fault current transformer before wiring the power supply.

298 1639502 12/2006

 Installation

GFCTs are specified with a transformation ratio. The ratio of the GFCT is the ratio
of the ground fault current sensed to the current which it outputs.
Set the parameters Ground CT Primary (the first number of the GFCT ratio) and
Ground CT Secondary (the second number of the GFCT ratio) to enable the
controller to correctly measure the actual ground fault current flowing in the circuit.
For more information, see p. 317.
For a description of GFCT characteristics, see p. 15.

1639502 12/2006 299

Installation

Wiring - Temperature Sensors

Temperature The LTM R controller has 2 terminals dedicated to temperature sensing protection:
Sensors T1 and T2. These terminals return the temperature value measured by resistance
temperature detectors (RTDs).
One of the following types of motor temperature sensor can be used:
z PTC Binary
z PTC Analog
z NTC Analog

This function applies to both single-phase and 3-phase motors.

The following table shows the maximum wire lengths for temperature sensor elements:

mm2 (AWG) 0.5 (20) 0.75 (18) 1.5 (16) 2.5 (14)

m (ft) 220 (656) 300 (985) 400 (1312) 600 (1970)

Use twisted pair wiring to connect the Controller to the temperature sensor. For the
Controller to accurately measure the resistance of the temperature-sensing
element, you must measure the resistance of the twisted-pair and add it to the
desired resistance for protection. This compensates for the lead resistance.
See p. 59 and p. 115 for more information on temperature sensors.
See p. 289 for an example of a wiring diagram using a temperature sensor.

Commissioning

Introduction

Introduction Commissioning must be performed after the physical installation of the LTM R controller,
expansion module and other hardware devices.
The commissioning process includes:
z initialization of the installed devices, and
z configuration of the LTM R controller parameters that are required for operation
of the LTM R controller, expansion module, and other system hardware
The person performing commissioning must be familiar with the system hardware,
and how it will be installed and used in the application.
Hardware devices can include:
z motor
z voltage transformers
z external load current transformers
z ground current transformers
z communication network
The product specifications for these devices provide the required parameter
information. You need to understand how the LTM R controller will be used to be
able to configure the protection, monitoring, and control functions for the application.
For information about configuring control parameters, see p. 207.
For information about configuring protection parameters, see p. 115.

316 1639502 12/2006

 Commissioning

Initialization The LTM R controller is ready to be initialized after the hardware installation is
complete. To initialize the LTM R controller:
z be sure the motor is off, then
z turn on the LTM R controller

CAUTION
IMPROPER INITIALIZATION
Disconnect power to the motor before initializing the LTM R controller.
Failure to follow this instruction can result in injury or equipment damage.

Neither the LTM R controller nor the expansion module require additional hardware
configuration (for example, turning dials, or setting dip-switches) to be initialized.
When powered up for the first time, the LTM R controller enters an initial state and
is ready for commissioning.

Configuration Identify the configuration control source–and the configuration tool–before

Tools configuring parameters. The LTM R controller and expansion module can be
configured locally using an HMI device or remotely via the network connection.
The LTM R controller can be commissioned using:
z a Magelis® XBTN410 HMI on which a 1-to-1 software application has been installed
z a PC running PowerSuite™ software
z a PLC connected to the LTM R controller’s network port.
The following parameters identify the configuration control source:
Parameter Enables use of this tool Factory setting
Config Via HMI Keypad Enable Magelis XBTN410 device keypad Enabled
Config Via HMI Engineering Tool Enable PC running PowerSuite software Enabled
Config Via Network Port Enable the network port (PLC) Enabled

Note: The Magelis XBTN410 HMI can commission the LTM R controller only if a 1-to-1
software application is installed. If a 1-to-many software application is installed, the
Magelis XBTN410 HMI can operate up to 8 LTM R controllers after commissioning,
but cannot perform commissioning for any LTM R controller. For information on the
use of software application files, see p. 345.

This chapter describes commissioning performed using either the Magelis

XBTN410 HMI in a 1-to-1 configuration, or PowerSuite software.

Commissioning The commissioning process remains the same, regardless which configuration tool
Process you select. This process includes the following stages:
Stage Description
First power-up The LTM R controller initializes, and is ready for parameter
configuration.
Configuring required settings Configure these parameters to move the LTM R controller
out of its initialization state. The LTM R controller is ready
for operations.

First Power-up

Overview First power-up describes the first time power is cycled to:
z a new LTM R controller, or
z an LTM R controller that has been previously commissioned, but whose parameter
settings have been restored to the factory defaults, either as a result of:
z execution of the Clear All Command, or
z a firmware upgrade

On first power-up, the LTM R controller enters a locked, non-configured state–called

the initialized state–and the Controller System Config Required parameter is turned
On. The LTM R controller exits this state only after certain parameters–called
required parameters–have been configured.
Using the Magelis® XBTN410 HMI, configuring the SysConfig menu parameters
clears the Controller System Config Required parameter and brings the LTM R
controller out of initialization.
Using PowerSuite™ software, all parameters–both required and optional–are
configured offline, then downloaded to the LTM R controller in a configuration file. A
successful download clears the Controller System Config Required parameter, and
brings the LTM R controller out of initialization.
In either case, the LTM R controller is no longer locked, and is ready for operations.
For information on operating states, see p. 214.
In a 1-to-1 configuration, the Magelis XBTN410 HMI displays the SysConfig menu
the very first time the LTM R controller powers up. The SysConfig menu contains
parameters that are essential to the operation of the LTM R controller and must be
configured during commissioning.
After the SysConfig menu parameters are configured and saved, the HMI closes the
SysConfig menu and displays the Main menu. The Main menu contains additional
parameters with factory default settings that also must be configured as part of the
commissioning process.

1639502 12/2006 321

Commissioning Using PowerSuite™ Software

Introduction A PC running PowerSuite software can commission the LTM R controller by

configuring required parameters at first power-up.
The procedure to configure parameters using PowerSuite software is the same, both
at first power-up, or at any later time. In all cases, use PowerSuite software to:
1 configure parameters offline
2 save your settings to a configuration file
3 transfer the configuration from your PC to the LTM R controller
For information about configuring parameters using PowerSuite software, see
p. 440.
For information about working with configuration files, including transferring configuration
settings from your PC to the LTM R controller, see p. 434.

Verify Configuration

Overview The final step in the commissioning process is to verify that all configurable
parameters used in your application are properly configured.
When performing this task, you will need a master list of all the parameters you
intended to configure and their desired settings. You must compare the actual
settings of configured parameters against this list.

Tools Only PowerSuite™ software can display all configured parameters, including both required
and optional parameters. These are found in the Settings branch of the tree control.
The Magelis® XBTN410 HMI can display all parameters in its Main menu, but cannot
display all parameters located only in its Sys Config menu.

Process Verifying parameter settings is a 3-part process:

1 Transfer the configuration file from the LTM R controller to the PowerSuite
software running in your PC. This lets you view the LTM R controller’s present
parameter settings.
For information on transferring files from the LTM R controller to your PC, see
p. 435.
2 Compare the master list of intended parameters and settings against the same
settings located in the Settings branch of PowerSuite software’s tree control.
3 Change the configuration settings as desired. Do this using either:
z PowerSuite software, then download the edited file from your PC to the LTM R controller
For information on transferring files from your PC to the LTM R controller, see

Editing Values (1-to-1)

Overview ENTER
Use the , , , and ESC buttons to select and edit settings. There are 2 ways
to edit setting values using the Magelis® XBTN410 HMI in a 1-to-1 configuration:
z selecting an item in a value list
z editing a numerical value one digit at a time

Note: Some settings, although expressed as numerical values, are selected in the
same manner as an item in a value list. For example, a setting with a value that is
expressed in units, but can be incremented or decremented only by tens or
hundreds of units, is edited by scrolling through a value list.

Editing any value requires familiarity with the Magelis XBTN410 menu structure, and
general navigation principles. For information on menu navigation, see p. 359. For
information on the menu structure, see p. 364.

Menu Structure (1-to-1)

Overview In a 1-to-1 configuration, the Magelis® XBTN410 HMI menu structure includes two
configurable menus:
z Sys Config menu
z Main menu
Each menu consists of up to 7 levels of nested parameters. When using the Magelis
XBTN410 HMI to navigate to an editable setting or to a read-only value, you must
be aware of the menu structure and the location of your destination parameter.

Sys Config Menu The Sys Config menu:

z opens on first power-up of the LTM R controller
z contains basic settings for operating the LTM R controller, expansion module,
and equipment
z closes after its settings are saved
The Sys Config menu is configured as part of the commissioning process. For
information on the Sys Config menu, see p. 328.

Main Menu The Main menu:

z appears on power-up of the LTM R controller after the Sys Config menu settings
have been saved, if no fault or warning is active
z contains optional configuration settings for the LTM R controller, expansion
module and equipment
z closes if no key is pressed within 10 seconds
z re-opens by pressing the ENTER key
If the motor is running when the LCD displays the Main menu, some parameters
cannot be re-configured and some commands cannot be executed, including:
z Load CT Ratio
z Motor Operating Mode
z Fault Reset Mode (during a fault condition)
z Clear All Command.

Saving Settings Only configurable parameter settings—the Sys Config menu parameters and the
Main menu’s Settings sub-menu parameters—can be saved to a file and
subsequently downloaded to a replacement LTM R controller. Use PowerSuite™
software to save and download settings.
The Main menu’s Statistics, Services, and Product ID sub-menus are not saved and
therefore cannot be downloaded to a replacement LTM R controller.

Scrolling Parameter List

The LCD display automatically presents a scrolling list of parameters and their
dynamically changing values if:
z there is no fault or warning, and
z parameters have been selected in the HMI Display sub-menu.
The scrolling parameter list:
z presents parameters in the same order they appear in the HMI Display sub-menu
z displays each parameter for 2 seconds, then moves to the next parameter
z returns to the first selected parameter in the list after reaching the end of the list.

HMI Password Use HMI password protection to prevent unauthorized configuration of LTM R controller
parameters from the HMI. The password must be an integer from 0000 to 9999. A
password value of 0000 disables password protection. Password protection is
disabled by default.
The process of entering a password is similar to editing a numerical setting. Editing
any value requires familiarity with the Magelis® XBTN410 menu structure, and
general navigation principles. For information on menu navigation, see p. 359. For
information on the menu structure, see p. 364.

HMI Keypad Control (1-to-1)

Overview In a 1-to-1 configuration, the functionality of the Stop and Reset buttons remain constant,
whereas the functionality of the HMI keypad Aux1 and Aux2 keys depends on the:
z selected operating mode, and
z control wiring.
Remember that the HMI keypad commands the LTM R controller’s logic outputs
only when:
z logic input I.6 is inactive, and
z Control Local Channel Setting parameter is set to Local HMI.

Stop, Reset The functions of the following keys do not vary according to the operating mode
selection in a properly wired configuration:
Key Function
STOP Stops the motor.
RESET Resets the LTM R controller after a fault.

1639502 12/2006 393

Use

Aux1, Aux2 The functions of the Aux1 and Aux2 buttons typically are configured as follows:
Operating mode Aux1 function Aux2 function
2 Speed Run Slow (O.1) Run Fast (O.2)
2 Step Run motor (O.1) Set bits in memory
Independent Control O.1 Control O.2
Overload Set bits in memory Set bits in memory
Reverser Run Forward (O.1) Run Reverse (O.2)

Note: The above key function assignments represent a typical configuration.

However, the actual functionality of any function key depends on wiring choices.

The behavior of the Aux1 and Aux2 keypad buttons varies according to the
operating mode and wiring configuration, as follows:
Key Can be used to:
Aux1 z control the closing of the NO O.1 contacts 13-14 to energize the operating of
a coil or motor
z set a bit in LTM R controller memory but control no logic output.

Aux2 z control the closing of the NO O.2 contacts 23 - 24 to energize either:

z another operating coil on the same motor
z an operating coil on another motor
z set a bit in LTM R controller memory but control no logic output.

Fault Management (1-to-many)

Overview When a fault occurs, the Magelis® XBTN410 HMI automatically opens a fault
display, consisting of 1 page for each active fault. Each page contains the:
z fault name
z address of the LTM R controller experiencing the fault
z total number of unresolved faults

Fault Display A typical fault display page looks like this:

Pages 1 2
1/ 2

THERMAL OVERLOAD 3

Motor-Starter 1 4
1 fault display page number
2 total number of active faults
3 fault name (flashing)
4 address of LTM R controller experiencing the fault (flashing)

If more than 1 fault is active, use the and keypad buttons to move back and
forth through the fault display pages.
Because some fault messages contain more than 4 lines of text, you may need to
use the and keypad buttons to scroll up and down within a fault display page
and display the entire fault message.

Opening / The 1-to-many HMI automatically opens the fault display whenever a fault occurs.
Closing the Fault When you remove the cause of a specific fault and execute a fault reset command,
Display that fault no longer appears in the fault display.

You can also close the fault display by clicking the ESC keypad button. This does
not fix the underlying cause of any fault, nor it does not clear any fault. You can re-
open the fault display at any time by navigating to the Home page, scrolling to the
Faults command line, then clicking the keypad button.
If you open the fault display when no faults are active, the HMI displays the message
"No Faults Present".

File Management

Overview The LTM R controller’s configuration settings are contained in an electronic

configuration file. Use PowerSuite software to manage the LTM R controller’s
configuration files by:
z creating a new configuration file for editing
z transfer configuration settings from the LTM R controller to the configuration
software running on your PC
z opening configuration settings for editing
z saving edited configuration settings to a file on your PC’s hard disk, or to other media
z transferring saved or edited configuration files from your PC to the LTM R controller.

Power-up Every time you open the configuration software, it presents the Load Configuration
dialog. Use this dialog to select the configuration settings that will be displayed when
the configuration software opens. You can select:
z the factory default configuration settings, or
z any previously saved configuration settings file.

Creating Files The recommended way to create a configuration file is to transfer a configuration
from the LTM R controller and save it. When you do this, all of the descriptive
information about the LTM R controller and expansion module is automatically
retrieved and copied to your PC.
When you create a new file using the File menu’s New Configuration command,
you must manually input this information, which is internally stored by the devices
but may not otherwise be readily available.

Note: When you edit the network protocol for either a new configuration file, or for
a configuration file transferred from the LTM R controller, the configuration
software automatically changes network settings to their default values for the
selected network protocol.

434 1639502 12/2006

 Use

File Transfer - To transfer configuration settings from the LTM R controller to the PC and save
Device to PC those settings in a new configuration file:
Step Action
1 Be sure the configuration software is communicating with the LTM R controller:
If the task bar indicates "Disconnected", select Connect in either the icon bar or
in the Link menu.
2 Transfer the configuration from the LTM R controller to your PC. Select Device
to PC in either the icon bar or the Link to File → Transfer sub-menu.
3 After the configuration settings are transferred, use the configuration software
to change configuration settings.
4 After your configuration setting edits are complete, save your work to a file:
z Select the Save command in either the icon bar or the File menu. The Save
As dialog opens.
- then -
z In the Save As dialog, navigate to the desired location and click Save.

Saving Files Save a copy of any configuration file you intend to transfer to the LTM R controller.
A saved copy provides both a record of these settings, and a backup that can be
used to re-transfer configuration settings if the initial transfer fails.
Use the:
z Save command to save your configuration changes to the open configuration file
z Save As command to save a copy of the displayed configuration to a separate file.

Note: If you opened the file containing the factory default configuration settings,
you cannot make and save changes to this file. Instead, you must use the Save As
command to save your changes under another file name.

By default, the configuration software stores saved files in a folder named

"Configurations". This folder is located on your hard drive in the same place the
configuration software was installed.
To designate a different default file storage folder:
Step Action
1 In the Settings menu, select Preferences. The Preferences dialog opens.
2 In the Preferences dialog, open the Configuration tab.
3 In the Configuration tab type in the folder name and path for saving configuration files.
4 Click OK to close the Preferences dialog and save your changes.

1639502 12/2006 435

Use

File Transfer - After you have edited a configuration file, you can transfer the file to the LTM R
PC to Device controller. Before the configuration software can make this transfer, the following
conditions must exist:
z at least one setting in the configuration file must be different than the same setting in the
LTM R controller - i.e., the software only overwrites settings with different values
z current must be less than 10% of FLC - i.e., online current must not be detected.

Note: When you transfer a configuration file from the PC to the LTM R controller,
the software checks to confirm that the LTM R controller and the configuration file
both use the same:
z current range, and
z network protocol

If there is a mismatch, the software asks if you wish to proceed. If you elect to
proceed, the software transfers all matching parameters, excluding parameters
that fail a range check. When the transfer is complete, the software displays the
names and addresses of parameters that failed the range check and were not
transferred.

To transfer a configuration file from the PC to the LTM R controller:

Step Action
1 Be sure the configuration software is communicating with the LTM R controller:
If the task bar indicates "Disconnected", select Connect in either the icon bar or
in the Link menu.
2 Be sure the file to be transferred is in the Main window. To open a file:
z select the Open Configuration command in either the icon bar or the File
menu. The Open dialog opens.
- then -
z in the Open dialog, navigate to the desired location and click Open.

3 Transfer the configuration from your PC to the LTM R controller. Select PC to

Device in either the icon bar or the Link to File → Transfer sub-menu.

General Information on Implementation via Profibus-DP

Overview The Profibus-DP LTM R controller supports a Profibus application profile based on
DP V0 and DP V1 services: Motor Management Starter (MMS).

Cyclic/ Acyclic In general, data is exchanged via cyclic services and via acyclic services.
Services The application profiles define, for the cyclic data:
z manufacturer independent data,
z manufacturer specific data.
The fixed set and defined use of manufacturer independent data enables the
replacement of a module from vendor A by a module from vendor B.

DP V1 Read/ DP V1 read and write services enable access to the data that cannot be accessed
Write Services by cyclic data exchange.

PKW Feature In order to make this data accessible also for DP V0 masters, a special feature,
called PKW (Periodically Kept in acyclic Words), is implemented.
In cyclically exchanged data, there are encapsulated request and response frames.
They provide access to TeSys T system´s internal registers.
See PKW: Encapsulated Acyclic Accesses in DP V0, p. 465.

Note: This feature can be selected or deselected by choosing the relevant item (module)
from the list offered during configuration with any Profibus configuration tool.

1639502 12/2006 451

PKW: Encapsulated Acyclic Accesses in DP V0

Overview Some Profibus masters do not provide DP V1 services. The PKW (Periodically Kept
in acyclic Words) feature is implemented to allow acyclic read or write accesses to
be encapsulated in DP V0.
This feature is enabled in the Profibus-DP configuration tool by selecting the
appropriate module. For each module, a second entry with PKW exists.
The PKW data is added to the cyclic data.

0/1 W_MB_32 b7-b0 b15-b8 b23-b16 b31-b24

Any changes in this object will trigger the handling of the request (except if Function
code [b6..b0] = 0x00).

Note: The highest bit of function code (bit 7) is a toggle bit.

It must change for each consecutive request.

This mechanism allows the request initiator to detect that a response is ready by
polling bit 7 of function code. When this bit in the OUT data becomes equal to the
request's emitted toggle bit in the IN data (when starting the request), then the
response is ready.
To provide versatility, the object address is specified ONLY as a register index (see
Communication Variables tables). The function code must be chosen according to
the addressing mode.
The Periodic registers service function codes are:

If the initiator tries to write a TeSys® T object or register to an unauthorized value,

or tries to access an inaccessible register, an error code is answered (Function code
= toggle bit + 0x4E). The exact error code can be found in bytes 4 and 5. The request
is not accepted and the object or register remains at the old value. This also
happens if an access is requested with an incorrect data type (example: R_MB_16
for reading a 32-bit TeSys® T register).
If you want to re-trigger exactly the same command, you must:
z reset the Function code to 0x00,
z wait for the response frame with the function code equal to 0x00, then
z set it again to its previous value.

This is useful for a limited master like an HMI.

Another way of re-triggering exactly the same command is to:
z invert the toggle bit in the function code byte.

The response is valid when the toggle bit of the response is equal to the toggle bit
written in the answer (this is a more efficient method, but it requires higher
programming capabilities).

Acyclic Data Read/Write via Profibus-DP V1

Overview For Acyclic DP V1 access, a mechanism based on slot/index and length-addressing

is implemented in the LTM R controller.

Note: All accessible registers are described in the Communication variable tables.
They are organized in groups (Identification variables, Statistics variables,...) and
sub-groups, if necessary.

Variables are accessed every 10 registers. You cannot access registers located
between two sub-groups. If the access is not possible, no register is accessed and
an error value (e.g. "not all registers found") will be returned via DP V1.

Reading Acyclic With DS_Read function, the Profibus-DP master can read data from the slave.
Data (DS_Read) Below is the contents of a frame that is to be sent:
Byte Syntax
0 [Function Number] 0x5E [DS_Read Function]
1 [Slot Number] Constant value = 1
2 [Index] Register address / 10
Common access to registers is every 10 registers.
The index is always rounded down to an integer.
3 [Length] Length of data blocks in bytes
(Number of registers) x 2
Maximum number of registers = 20 (40 bytes)
Any length between 2 and 40 bytes is possible.
4 to (length + 3) Block of data bytes to be read.

Sending Acyclic With DS_Write function, the Profibus DP master can send data to the slave.
Data (DS_Write) Before writing a block of data, it is recommended to read a block of data first, in order
to protect data that is not impacted. The whole block will only be written if you have
writing rights, to be checked within each register table in the Communication
variables tables. Column 3 table headers indicate if the variables within each table
are Read-only or Read/Write.

The presentation of an error code and an error class to the user logic depends on
the master implementation (for example, the PLC).
The mechanism only accesses blocks of parameters starting at a dedicated
parameter (MB address). This means that unused parameters (MB addresses) are
also accessed. The data value read from theses parameters is 0x00; but in case of
writing, it is necessary to write the value 0x00 to these parameters. Otherwise, the
complete write access will be rejected.

User Map Details User Map allows you to read values of non-contiguous registers in a continuous way.
Information is organized into 2 tables containing addresses and values.
The first table stores the addresses of registers to be read or written. By default, all
addresses are null, which means that the addresses have not been assigned.

Modbus Register Map - Organization of Communication Variables

Introduction Communication variables are listed in tables, according to the group (such as identification,
statistics, or monitoring) to which they belong. They are associated with an LTM R
controller, which may or may not have an LTM E Expansion Module attached.

Communication Communication variables are grouped according to the following criteria:

Variable Groups
Variable groups Registers
Identification variables 00 to 99
Statistics variables 100 to 449
Monitoring variables 450 to 539
Configuration variables 540 to 699
Command variables 700 to 799
User Map variables 800 to 999
Custom Logic variables 1200 to 1399

Table Structure Communication variables are listed in 4-column tables:

Column 1 Column 2 Column 3 Column 4
Register (in decimal format) Variable type (see p. 478) Variable name and access Note: code for additional

Note The Note column gives a code for additional information.

Variables without a code are available for all hardware configurations, and without
functional restrictions.
The code can be:
z numerical (1 to 9), for specific hardware combinations
z alphabetical (A to Z), for specific system behaviors.

If the note is... Then the variable is available for...

1 the LTM R + LTM EV40 combination
2-9 future combinations

If the note is... Then...

A the variable can be written only when the motor is off
B the variable can be written only in configuration mode
C the variable can be written only with no fault
D-Z the variable is available for future exceptions

Unused Unused addresses fall into 3 categories:

Addresses z Not significant, in Read-only tables, means that you should ignore the value
read, whether equal to 0 or not.
z Reserved, in Read/Write tables, means that you must write 0 in these variables.
z Forbidden, means that read or write requests are rejected, that these addresses
are not accessible at all.

Integer (Int, UInt, Integers fall into the following categories:

DInt, IDInt) z Int: signed integer using one register (16 bits)
z UInt: unsigned integer using one register (16 bits)
z DInt: signed double integer using two registers (32 bits)
z UDInt: unsigned double integer using two registers (32 bits)

For all integer-type variables, the variable name is completed with its unit or format,
if necessary.
Example:
Address 474, UInt, Frequency (x 0.01 Hz).

Word Word: Set of 16 bits, where each bit or group of bits represents command,
monitoring or configuration data.
Example:
Address 455, Word, System Status Register 1
bit 0 System ready
bit 1 System on
bit 2 System fault
bit 3 System warning
bit 4 System tripped
bit 5 Fault reset authorized
bit 6 (Not significant)
bit 7 Motor running
bits 8-13 Motor average current ratio
bit 14 Control via HMI
bit 15 Motor starting (in progress)

Word[n] Word[n]: Data encoded on contiguous registers.

Examples:
Addresses 64 to 69, Word[6], Controller Commercial Reference
(see DT_CommercialReference)
Addresses 655 to 658, Word[4], Date and Time setting (see DT_DateTime).

Identification and Maintenance Functions (IMF)

IM Index Space In order to avoid conflicts with any Profibus-DP devices already installed in the field
and Partitions and to save address space for operational parameters, the I&M proposal follows the
CALL_REQ service defined within IEC 61158-6.
This service, part of the "Load Domain" Upload/Download services, can be used
within any module independent from any directory in a representative module
(e.g. slot 0) of a device. It uses index 255 within any slot and opens a separate
addressable sub-index space. For I&M functions, the sub-index range from 65000
to 65199 is reserved. Sub-index blocks are called IM_Index.

65000 Basic I&M (mandatory)

“CALL” 65004
Index = 255
65005 Basic I&M (reserved)
(I&M) .....

..... I&M
.....
65099
65100 Manufacturer specific
..... I&M
.....
65199
IM_INDEX

Index = 0

Slot x

The CALL_REQ service needs several header bytes, reducing the possible net data
length to 236 bytes.

1639502 12/2006 519

Use

For I&M functions the following block of sub indices (IM_INDEX) will be used:

IM_INDEX Usage
65000 I&M0
65001 I&M1
65002 I&M2
65003 I&M3
65004 I&M4
65005 ... 65015 Reserved for additional general I&M functions
65016 ... 65099 Profile specific I&M functions
65100 ... 65199 Manufacturer specific I&M functions

I&M0 - The The transport of the I&M parameters across the Profibus network via MS1 (optional)
Mandatory or MS2 (mandatory) is supported. Only I&M0 data with IM0_Index = 65000 can be
Record read. No other IM_Indices are supported.
Structure of the I&M0 record:
// structure for I&M0 (mandatory)
typedef struct
{
UBYTE abHeader[10];
UWORD wManufacturerID;
UBYTE abOrderID[20];
UBYTE abSerialNumber[16];
UWORD wHardwareRevision;
UBYTE abSoftwareRevision[4];
UWORD wRevCounter;
UWORD wProfileID;
UWORD wProfileSpecificType;
UBYTE abIMVersion[2];
UWORD wIMSupported;
} sIM0;

During startup of the firmware this structure is initialized with the relevant
information. A Profibus DPV1 master (MS1 or MS2) can read this information at any
time using the CALL_REQ mechanism.

Detecting Problems

Overview The LTM R controller and the expansion module perform self-diagnostic checks at
power-up and during operation.
Problems with either the LTM R controller or expansion module can be detected using:
z Power and Alarm LEDs on the LTM R controller
z Power and Input LEDs on the expansion module
z LCD Display on a Magelis® XBTN410 HMI device connected to the LTM R controller’s
Local HMI port
z PowerSuite™ software running on a PC connected to the LTM R controller’s

Troubleshooting

The LTM R controller performs self-diagnostic tests at power-up and during operation.
These tests, the errors they detect, and the steps to take in response to a problem
are described below:
Type Error Action
Major Internal temperature fault This fault indicates a warning at 80°C, a minor fault at 85°C, and a major
internal fault at 100°C. Take steps to reduce ambient temperature, including:
faults z add an auxiliary cooling fan
z remount the LTM R controller and expansion module to provide more
surrounding free space.
If the condition persists:
1 Cycle power.
2 Wait 30 s.
3 If the fault persists, replace the LTM R controller.
CPU failure These faults indicate a hardware failure. Take the following steps:
Program checksum error 1 Cycle power.
2 Wait 30 s.
RAM test error
3 If the fault persists, replace the LTM R controller.
Stack overflow
Stack underflow
Watchdog timeout
Minor Invalid configuration error Indicates either a bad checksum (Config checksum error) or good
internal Configuration checksum checksum but bad data (Invalid config error). Both caused by hardware
faults (EEROM) error failure. Take the following steps:
1 Cycle power and wait 30 s.
2 Reset the configuration settings to factory defaults.
3 If the fault persists, replace the LTM R controller.
Internal network These faults indicate a hardware failure. Take the following steps:
communications failure 1 Cycle power and wait 30 s.
A/D out of range error 2 If the fault persists, replace the LTM R controller.

Maintenance

Preventive Maintenance

Overview The following protective measures should be performed between major system
checks, to help maintain your system and protect it against irrecoverable hardware
or software failure:
z continuously review operating statistics
z save LTM R controller parameter configuration settings to a backup file
z maintain the LTM R controller’s operating environment
z periodically perform a LTM R controller self test
z check the LTM R controller internal clock to ensure accuracy.

Statistics The LTM R controller collects the following types of information:

z real-time voltage, current, power, temperature, I/O and fault data
z a count of the number of faults, by fault type, that occurred since last power-up
z a time-stamped history of the state of the LTM R controller—displaying measures
of voltage, current, power, and temperature—at the moment that each of the
previous 5 faults occurred.
Use either PowerSuite™ software or a Magelis® XBTN410 HMI to access and
review these statistics. Analyze this information to determine whether the actual
record of operations indicates a problem.

Configuration In the event of irrecoverable LTM R controller failure, you can quickly restore
Settings configuration settings if you saved these settings to a file. When the LTM R
controller is first configured—and every subsequent time any configuration settings
are changed—use PowerSuite software to save the parameter settings to a file.
Using PowerSuite software:
z To save a configuration file:
1. Select File → Print → To File.
z To restore the saved configuration file:
1. Open the saved file: Select File → Open (then navigate to and open the file.)
2. Download the configuration to the new controller:
Select Link → Transfer → Device to PC.

 Maintenance

Environment Like any other electronic device, the LTM R controller is affected by its physical environment.
Provide a friendly environment by taking common-sense preventive measures, including:
z Scheduling periodic examinations of battery packs, fuses, power strips, batteries,
surge suppressors, and power supplies.
z Keeping the LTM R controller, the panel, and all devices clean. An unobstructed
flow of air will prevent dust build-up, which can lead to a short-circuit condition.
z Remaining alert to the possibility of other equipment producing electromagnetic radiation.
Be sure no other devices cause electromagnetic interference with the LTM R controller.

Self Test Perform a self test by either:

z holding down the Test/Reset button on the face of the LTM R controller for more
than 3 seconds and up to 15 seconds, or
z setting the Self Test Command parameter.
A self test can be performed only if:
z motor is off
z no faults exist
z the Self Test Enable parameter is set

Note: Performing a self test when the motor is on triggers a Thermal Overload fault.

The LTM R controller performs the following checks during a self test:
z watchdog check
z RAM check
z recalibration of the thermal memory time constant, which keeps track of time
while the LTM R controller is not powered
If any of the above tests fails, a major internal fault occurs. If not, the self test
continues and the LTM R controller performs:
z expansion module test (if it is connected to an expansion module). If this test fails:
z the LTM R controller experiences a minor internal fault
z the expansion module experiences an internal fault
z internal communication (communication brick) test. If this test fails, the LTM R
controller experiences a minor internal fault
z LED test: turns all LEDs off, then turns each LED on in sequence, then turns all
LEDs on, then returns LEDs to their initial state
z output relay test: opens all relays, and restores them to their original state only after:
z a reset command executes, or
z power is cycled

During a self test, the LTM R controller sets the Self Test Command parameter to 1.
When the self test finishes, this parameter is reset to 0.

1639502 12/2006 527

Maintenance

Internal Clock To ensure an accurate record of faults, be sure to maintain the LTM R controller’s
internal clock. The LTM R controller time stamps all faults, using the value stored in
the Date And Time Setting parameter.
Internal clock accuracy is +/-1 second per hour. If power is continuously applied for
1 year, the internal clock accuracy is +/-30 minutes per year.
If power is turned Off for 30 minutes or less, the LTM R controller retains its internal
clock settings, with accuracy of +/- 2 minutes.
If power is turned Off for more than 30 minutes, the LTM R controller resets its
internal clock to the time when power was turned Off.

Replacing an LTM R Controller and LTM E Expansion Module

Overview Questions to consider in advance of replacing either an LTM R controller or an

LTM E expansion module are:
z is the replacement device the same model as the original?
z have the configuration settings of the LTM R controller been saved, and are they
available to be transferred to its replacement?
Be sure the motor is turned off before replacing either the LTM R controller or the
LTM E expansion module.

Replacing the The time to plan for the replacement of an LTM R controller is:
LTM R Controller z when the LTM R controller settings are initially configured, and
z any time that one or more of its settings are subsequently re-configured
Because setting values may not be accessible when the LTM R controller is
replaced–for example, in case of device failure–you should create a record of setting
values whenever they are made.
Using PowerSuite™ software, all of the LTM R controller’s configured settings—
except for date and time—can be saved to a file. Once saved, you can use
PowerSuite software to transfer these settings either to the original LTM R controller
or to its replacement.

Note: Only configured settings are saved. Historical statistical data is not saved,
and therefore cannot be applied to a replacement LTM R controller.

For information on how to use PowerSuite software to create, save and transfer
configuration setting files, see p. 434.

Replacing the The primary consideration in replacing an LTM E expansion module, is to replace it
Expansion with the same model–24Vdc or 110-240Vac–as the original.
Module

Retiring Devices Both the LTM R controller and the LTM E expansion module contain electronic
boards that require particular treatment at the end of their useful life. When retiring
a device be sure to observe all applicable laws, regulations and practices.

Communication Warnings and Faults

Introduction Communication warnings and faults are managed in a standard way, like any other
types of warnings and faults.
The presence of a fault is signalled by various indicators:
z State of the LEDs (1 LED is dedicated to communication: BF, see p. 331)
z State of the output relays
z Warning
z Message(s) displayed on HMI screen
z Presence of an exception code (such as a report from the PLC)

530 1639502 12/2006

 Maintenance

PLC A communication loss is managed like any other fault.

Communication The LTM R controller monitors the communication with the PLC. Using an
Loss adjustable network idle time (timeout), the LTM R controller watchdog function can
report a network loss (firmware watchdog). In the event of a network loss, the LTM R
controller can be configured to take certain actions. These depend on the control
mode that the LTM R controller was operating in prior to the network loss.
If PLC-LTM R controller communication is lost while the LTM R controller is in network
control mode, the LTM R controller enters the fallback state. If PLC- LTM R controller
communication is lost while the LTM R controller is in local control mode, and then
the control mode is changed to network control, the LTM R controller enters the
fallback state.
If PLC-LTM R controller communication is restored while the control mode is set to
network control, the LTM R controller exits the fallback state. If the control mode is
changed to local control, the IMPR exits from the fallback state, regardless of the
state of PLC-controller communications.
The table below defines the available actions that the LTM R controller may take during a
communication loss that the user may select when configuring the LTM R controller.
Network Communication Loss Actions:
LTM R controller output control Available LTM R actions after PLC - LTM R controller
mode prior to network loss network loss
Local Terminal Strip Fault and Warning control possibilities:
- Signal nothing
- Activate a warning
- Activate a fault
- Activate a fault and warning
Local RJ45 Fault and Warning control possibilities:
- Signal nothing
- Activate a warning
- Activate a fault
- Activate a fault and warning
Remote Fault and Warning control possibilities:
- Signal nothing
- Activate a warning
- Activate a fault
- Activate a fault and warning
- The behavior of the LO1 and LO2 relays depends on the
motor controller mode and on the fallback strategy chosen

Maintenance

HMI The LTM R controller monitors the communication with any approved HMI device.
Communication Using a fixed network idle time (timeout), the LTM R controller watchdog function
Loss can report a network loss. In the event of a communication loss, the LTM R controller
can be configured to take certain actions. These depend on the control mode that
the LTM R controller was operating in prior to the communication loss.
If HMI-controller communication is lost while the LTM R controller is in Local RJ45
control mode, the LTM R controller enters the fallback state. If HMI-LTM R controller
communication is lost while the LTM R controller is not in Local RJ45 control mode,
and then the control mode is changed to Local RJ45 control, the LTM R controller
enters the fallback state.
If HMI-controller communication is restored while the control mode is set to Local
RJ45 control, the IMPR exits from the fallback state. If the control mode is changed
to Local Terminal Strip or Network control, the IMPR exits from the fallback state,
regardless of the state of HMI-controller communications.
The table below defines the available actions that the LTM R controller may take during
a communication loss. Select one of these actions when configuring the LTM R controller.
Local RJ45 Communication Loss Actions:
LTM R controller output control Available LTM R controller actions after HMI -
mode prior to network loss LTM R controller network loss
Local Terminal Strip Fault and Warning control possibilities:
- Signal nothing
- Activate a warning
- Activate a fault
- Activate a fault and warning
Local RJ45 Fault and Warning control possibilities:
- Signal nothing
- Activate a warning
- Activate a fault
- Activate a fault and warning
Remote Fault and Warning control possibilities:
- Signal nothing
- Activate a warning
- Activate a fault
- Activate a fault and warning
- The behavior of the LO1 and LO2 relays depends on the
motor controller mode and on the fallback strategy chosen

Note: For information about a communication loss and the fallback strategy to
follow, see p. 104.

1 A Dahlander application requires 2 sets of wires passing through the CT windows. The
controller can also be placed upstream of the contactors. If this is the case, and if the
Dahlander motor is used in variable torque mode, all the wires downstream of the
contactors must be the same size.
2 The N.C. interlock contacts KM1 and KM2 are not mandatory because the controller
electronically interlocks O.1 and O.2.

active power Also known as real power, active power is the rate of producing, transferring or using
electrical energy. It is measured in watts (W) and often expressed in kilowatts (kW)
or megawatts (MW). For single-phase motors its calculation is:
is:

Active Power = (Apparent Power) x (Power Factor)

For 3-phase motors its calculation is:

is:

Active Power = (Avg. RMS Voltage) × (Avg. RMS Current) × 3 × (Power Factor)

analog Describes inputs (e.g. temperature) or outputs (e.g. motor speed) that can be set to
a range of values. Contrast with discrete.

apparent power The product of current and voltage, apparent power consists of both active power
and reactive power. It is measured in volt-amperes and often expressed in kilovolt-
amperes (kVA) or megavolt-amperes (MVA). Its calculation is:

Apparent Power = (Avg. RMS Current) x (Avg. RMS Voltage)

CANopen An open industry standard protocol used on the internal communication bus. The
protocol allows the connection of any standard CANopen device to the island bus.

CT current transformer.

definite time A variety of TCC or TVC where the initial magnitude of the trip time delay remains a
constant, and does not vary in response to changes in the value of the measured
quantity (e.g. current). Contrast with inverse thermal.

device In the broadest terms, any electronic unit that can be added to a network. More
specifically, a programmable electronic unit (e.g. PLC, numeric controller or robot)
or I/O card.

DeviceNet™ DeviceNet™ is a low-level, connection-based network protocol that is based on

CAN, a serial bus system without a defined application layer. DeviceNet, therefore,
defines a layer for the industrial application of CAN.

DIN Deutsches Institut für Normung. The European organization that organizes the
creation and maintenance of dimensional and engineering standards.

DIN rail A steel mounting rail, made pursuant to DIN standards (typically 35 mm wide), that
allows for easier "snap-on" mounting of IEC electrical devices, including the LTM R
controller and the expansion module. Contrast with screw mounting of devices to a
control panel by drilling and tapping holes.

discrete Describes inputs (e.g. switches) or outputs (e.g. coils) that can be only On or Off.
Contrast with analog.

DPST double-pole/single-throw. A switch that connects or disconnects two circuit

conductors in a single branch circuit. A DPST switch has 4 terminals, and is the
equivalent of two single-pole/single-throw switches controlled by a single
mechanism, as depicted below:

FLA full load amperes. Same as full load current (FLC).

FLC full load current. Also known as rated current. The current the motor will draw at the
rated voltage and rated load. The LTM R controller has two FLC settings: FLC1
(Motor Full Load Current Ratio) and FLC2 (Motor High Speed Full Load Current
Ratio), each set as a percentage of FLC max.

FLC1 Motor Full Load Current Ratio. FLC parameter setting for low or single speed
motors. Setting range: 5...100% of FLC max. Default setting: 25% of FLC max.

FLC2 Motor High Speed Full Load Current Ratio. FLC parameter setting for high-speed
motors. Setting range: 5...100% of FLC max. Default setting: 25% of FLC max.

FLCmax Full Load Current Max. Peak current parameter. Setting ranges from 1...8400 A in
increments of 0.1 A.

FLCmin Minimum Full Load Current. The smallest amount of motor current the LTM R
controller will support. This value is determined by the LTM R controller model, as
follows:
LTM R controller model FLCmin
LTMR08 0.40 A
LTMR27 1.35 A
LTMR100 5.00 A

hysteresis A value—added to lower limit threshold settings or subtracted from upper limit
threshold settings—that retards the response of the LTM R controller before it stops
measuring the duration of faults and warnings.

inverse thermal A variety of TCC where the initial magnitude of the trip time delay is generated by a
thermal model of the motor and varies in response to changes in the value of the
measured quantity (e.g. current). Contrast with definite time.

Modbus® Modbus® is the name of the master-slave/client-server serial communications

protocol developed by Modicon (now Schneider Automation, Inc.) in 1979, which
has since become a standard network protocol for industrial automation.

nominal power Motor Nominal Power. Parameter for the power a motor will produce at rated voltage
and rated current. Setting range: 0.1...999.9 kW, in increments of 0.1 kW. Default
setting: 7.5 kW.

nominal voltage Motor Nominal Voltage. Parameter for rated voltage. Setting range: 200...690 V.
Default setting: 480 V.

NTC negative temperature coefficient. Characteristic of a thermistor—a thermally

sensitive resistor—whose resistance increases as its temperature falls, and whose
resistance decreases as its temperature rises.

NTC analog Type of RTD.

PLC programmable logic controller.

power factor Also called cosine phi (or ϕ), power factor represents the absolute value of the ratio
of active power to apparent power in AC power systems, as
follows:

Active Power -
Power Factor = --------------------------------------
Apparent Power

Profibus An open bus system that uses an electrical network based on a shielded 2-wire line
or an optical network based on a fiber-optic cable.

PTC positive temperature coefficient. Characteristic of a thermistor—a thermally

sensitive resistor—whose resistance increases as its temperature rises, and whose
resistance decreases as its temperature falls.

PTC analog Type of RTD.

PTC binary Type of RTD.

reset time Time between a sudden change in the monitored quantity (e.g. current) and the
switching of the output relay.

rms root mean square. A method of calculating average AC current and average AC
voltage. Because AC current and AC voltage are bi-directional, the arithmetic
average of AC current or voltage always equals 0. The calculations for rms current
and rms voltage
are:

Irms = Imax
------------- Vrms = Vmax

Glossary

RTD resistance temperature detector. A thermistor (thermal resistor sensor) used to

measure the temperature of the motor. Required by the LTM R controller’s Motor
Temp Sensor motor protection function.

TCC trip curve characteristic. The type of delay used to trip the flow of current in response
to a fault condition. As implemented in the LTM R controller, all motor protection
function trip time delays are definite time, except for the Thermal Overload function,
which also offers inverse thermal trip time delays.

TVC trip voltage characteristic. The type of delay used to trip the flow of voltage in
response to a fault condition. As implemented by the LTM R controller and the
expansion module, all TVCs are definite time.
