Introduction

TeSys T is a motor management system that provides full motor monitoring, control, and protection when used with short circuit protection and a contactor. TeSys T manages most critical processes while reducing downtime and increasing productivity. TeSys T is a flexible system that integrates seamlessly into your automation system through five major communication protocols. TeSys T predicts what will happen in the process, as it accurately monitors current, voltage, and power over a wide range. TeSys T is a green motor management system with unique power monitoring capabilities for better energy management. TeSys T carries all appropriate and necessary third party certifications.

TeSys T detailed functionalities and possible configuration: Communication: TeSys T is a flexible motor management system that supports six major communication protocols: Modbus™, CANopen, DeviceNet™, Profibus™, Ethernet/IP, and Modbus/ TCP. These communication protocols allow the TeSys T controller to integrate seamlessly into your automation systems. Ethernet/IP and Modbus/TCP provide FDR to enable quick replacement of products and minimize maintenance time. Protection functions: • thermal overload

Motor control modes: 10 predefined motor control modes are incorporated in the controller. Each listed mode is available as 2 or 3 wire control. • overload mode: monitoring of motors whose control is not managed by the controller • independent mode: starting of full voltage non-reversing motors • reverser mode: starting of full voltage reversing motors • 2-step mode: 2-step starting of motors (star-delta, by autotransformer and by resistor) • 2-speed mode: 2-speed starting of motors (Dahlander, pole changer) A custom mode is available to allow the user to create a specific motor control mode that is not predefined in the controller. Custom Logic has the basic functions of a small programmable logic controller (PLC). Programming can be done in Structured Text mode or in Block Diagrams through SoMove™ software. To ensure consistency, the same software used to commission the TeSys T controller is used for Custom Logic programming. Statistical and diagnostic functions: • history of the last five detected faults • motor statistics • controller operations • warning of pending faults

• phase imbalance and phase failure • thermal motor protection via PTC probes • phase reversal • ground fault detection • long starting times and motor stalling • automatic load shedding and restarting • load fluctuations (current, voltage, power) • variations of Cos j (power factor) Metering functions: • Measurements (rms values): – current on the 3 phases – voltage on the 3 phases (shedding) • Values calculated: – average current – frequency – Power factor, power, power consumption Motor control functions: A motor managed by a TeSys T controller can be controlled: • locally, using the logic inputs present on the product, or via the human machine interface (HMI) • remotely, via the network – motor temperature – ground fault sensing
