Chapter 1: Introduction

This chapter provides an overview of the EPOS Motor Control System. Additional details are provided in subsequent
chapters.

1.1 Overview

The EPOS Electronics Protection and Object Control System is a motor protection system designed specifically
for low-voltage motor applications. It is comprised of the following modules:

EntelliPro ES: a modular control unit that represents the lowest level in the control
hierarchy of the EPOS system.

EntelliPro CT: a current transformer that is used in conjunction with EntelliPro
ES in a branch-drawout system.

WinESG: a Profibus base programmable software used to configure EntelliPro ES Alarm
handling, read and write parameters.

Optional EntelliPro CP3 or EntelliPro CP5: Modbus-based HMI (human-machine interface). One
HMI is provided as part of the MCC package and is programmed to display metering and other
parameters.
The EntelliPro ES can be programmed as an EntelliPro ES retrofit, where the Profibus telegrams match the ESS
DP device. Alternatively, the EntelliPro ES can be programmed as a non-retrofit unit, where additional Profibus
telegrams are made available.
The EntelliPro ES provides the following key features:

Flexible protection, control, and communication options to suit any low-voltage motor
application.

Small footprint designed specifically for IEC and NEMA MCC applications.

Modular design reduces the number of spare components for maintenance and testing.

DIN rail mounting.

Dual, simultaneous communication protocols (Modbus and Profibus) allow simple integration into
monitoring and control systems.

Multiple inputs and outputs.

Eleven pre-programmed motor starter types.

Programmable custom motor starter logic for complex systems.
