LTMR Controller

LTMR27EBD The controller is the central component in the motor management system. It manages the basic functions such as: • measurement of 3-phase current via integral current transformers from 0.4 to 100 A (up to 810 A by external current transformers) • measurement of ground current internally or external ground sensors • measurement of motor temperature • inputs and outputs for the various motor control modes, detected fault management, and other functions Characteristics As standard, the controller manages the following:

Control Modes • overload mode • independent mode • reverser mode • 2-speed mode • 2-step mode • custom mode Inputs/Outputs • 6 discrete logic inputs

16 NEMA AND DEFINITE PURPOSE CONTACTORS AND STARTERS

• 3 relay logic outputs (1 N.O. contact each) • 1 relay output for detected fault signaling (1 N.O. + 1 N.C.) overload relay • Measurements • connection for a thermistor probe • connections for a ground sensor
