Presentation of the LTMCU Control Operator Unit

Aim of the Product

The LTMCU Control Operator Unit is a remote operator terminal that enables the configuration, monitoring and control of the LTMR controller, as part of the TeSys^® T Motor Management System. The LTMCU has been specially developed to act as the Human Machine Interface (HMI) of the LTMR controller, and is internally powered by the LTMR.

The diagram below shows the LTM CU front face:

LTMCU Functions

The LTMCU can be used to:

configure parameters for the LTMR controller,
display information about the LTMR controller configuration and operation,
monitor trips and alarms by the controller,
control the motor locally using the local control interface.

LTMCU Languages

The LTMCU can display languages thanks to an embedded dictionary. The default (factory) language is English. You can also download and install 2 other languages via www.se.com. For more information on downloading languages, see Language Management.

Configuring the LTMR Controller Using SoMove™ with the TeSys T DTM

The LTMR controller can be configured using the LTMCU or a PC running SoMove with the TeSys TDTM..

SoMove software is a Microsoft^® Windows^®-based application, using the open FDT/DTM technology.

SoMove contains many DTMs. The TeSys T DTM is a specific DTM that enables the configuration, monitoring, control, and customization of the control functions of the LTMR controller, as part of the TeSys^® T motor management system.

LTMCU Assembly

There are 2 ways to use the LTMCU:

as a fixed HMI device, flush mounted in a panel and continuously connected to one LTMR controller Flush Mounting the LTMCU, or
as a portable HMI device, used from time to time to set and monitor several LTMR controllers. A separate kit (reference LTM9KCU) can be used to mount the portable LTMCU.

More Information in LTMR User’s Manuals

The User's Manual of the LTMR controller used is complementary to the present manual and needed for the system implementation. It contains the following information:

description of the functions (metering and monitoring, protection and control),
parameter values (including factory default),
installation and commissioning.
