TeSys T MMC Devices

System Overview

The TeSys T Motor Management Control (MMC) system consisting of controller and

expansion module devices, provides protection, control, and monitoring capabilities

for single-phase and 3-phase AC induction motors.

The system offers diagnostic and statistical functions, as well as configurable

warnings and faults. These features allow better prediction of component

maintenance, and provide data to continuously improve the entire system.

The system can be configured and controlled using an HMI device, a PC with

PowerSuite configuration software, or remotely over the network using a PLC.

Components such as external load current transformers and ground current

transformers provide additional range to the system.

Main Components

The two main hardware components of the TeSys T system are:

 LTMR controller

 LTME expansion module

The microprocessor-based LMTR controller is the central component in the system

and the expansion module provides additional functionality when it is installed with

the controller.

LMTR Controller

The microprocessor-based LMTR controller manages the control, protection and

monitoring functions of single-phase and 3-phase AC induction motors.

The LMTR control functions include:

 control channels (local/remote control source selection)

 operating modes

 fault management

The LMTR protection functions include:

 thermal motor protection

 current motor protection

 voltage and power motor protection

The LMTR metering and monitoring functions include:

 measurement

 fault and warning counters

 system and device monitoring faults

 motor history

 system operating status
