Protection &  Control

The 369 is a digital motor protection system designed to protect and manage medium sized AC motors and their driven equipment. It contains a full range of selectively enabled, self contained protection and control elements as detailed in the Functional Block Diagram and Features table.

Motor Thermal Model The primary protective function of the 369 is the thermal model with six key elements: • Overload Curves • Unbalance Biasing • Hot/Cold Safe Stall Ratio • Motor Cooling Time Constants • Start Inhibit and Emergency Restart • RTD Biasing

Inputs and Outputs 

 The 369 features a variety of digital input and output channels.  Any of the               

 programmable digital inputs may be selected and programmed as a separate General Switch, Digital Counter, or Waveform Capture Input. In addition the programmable digital inputs may be selected and programmed to perform one of the following functions: Emergency Restart, Differential Switch, Speed Switch, or Remote Reset as described below
