                             The LTM R controller
1                           The controller is the central component in the motor management system.
                            It manages the basic functions such as:
                            b measurement of 3-phase current via integral current transformers from 0.4 to
                            100 A (up to 810 A by external current transformers),
     526381
                             Characteristics
                            As standard, the controller manages the following predefined control mode
                            functions:
                            b overload mode,
              LTM Rpp       b independent mode,
3                           b reverser mode,
                            b 2-speed mode,
                            b 2-step mode,
                            b "Custom" mode.
                            Supply
                            2 types of controller power supply are available:
                            b c 24 V,
4                           b a 100…240 V.
                            Current ranges
                            3 current ranges allow measurement of motor current from 0.4 to 100 A:
                            b 0.4…8 A,
                            b 1.35…27 A,
                            b 5…100 A.
                            For use with external current transformers, choose the 0.4…8 A range (1 or 5 A
5                           current transformer secondary).
                            Inputs
                            b 6 discrete logic inputs.

                            b 2 types of power supply for the inputs: c 24 V and a 100…240 V.
                            A c 24 V controller can be assembled with an a 100…240 V extension module and
                            vice versa.

                                    Human/Machine Interfaces (HMI)
                                   Depending on the application, 2 types of HMI can be used with the LTM R controller.
                                   b The LTM CU operator control unit:
                                                                                                                              1
                                   v Entirely dedicated to the TeSys T range,
                                   v Only for control/monitoring of an LTM R controller.

                                   A language download utility (LangTool), together with all the other languages, are
                                   available on the website “www.schneider-electric.com”.                                     4
                                   This tool allows the languages present in the LTM CU control unit to be adapted.
                                   The LTM CU HMI control unit has an RJ45 port, protected by a flexible cover to
                                   provide a good level of protection (IP54).
                                   This port on the front panel allows connection to a PC, via a connecting cable, in
                                   order to use PowerSuite software.
                                   In this case, the control unit acts as a transmitter and all information can then be       5
                                   viewed in PowerSuite.
                                   XBT L1000 programming software is needed for loading applications into the HMI
                                   terminal.
                                   These applications are available on the website “www.schneider-electric.com”.

                                     Power extension (or Daisy chaining), at bus level, is another connection topology
Star topology                        commonly used in traditional, industrial automation system networks. The cable
                                     segments link several peripherals to each other, constituting the peripheral "section"
                                     of the network cable.

                               Ethernet ring
                               Ethernet rings are generally the main networks in applications where a high level of
2       TeSys T      TeSys T   reliability is required. If a ring topology is required, the switches handling this function
                               must be used.
                               Single ring
                               The first level of redundancy can be achieved by installing a single ring.
                               ConneXium switches can be used to establish main network ring configurations.
                               The ring is created using HIPER-Ring ports.
                               If a section of the line fails, the ring structure (including a maximum of 50 switches)
4                              converts into a line type configuration in less than 0.5 seconds.

                                                             b allow standardisation,

                                                             The functions thus defined can be saved and used to build your function library for

                                                             To create special functions, a logic editor is incorporated in the configurator and
                                                             allows a choice of 2 programming languages:

9    (1) For a Dahlander application, all the power cables must pass through current transformers. The controller can also be placed upstream of the contactor. In this
         case, and if the Dahlander motor is used in "variable torque" mode, all the cables downstream of the contactors must be of identical size.
     (2) Contacts for interlocking KM1 and KM2 are not obligatory because the controller electronically interlocks outputs O.1 and O.2.
