EPOS Motor Management System
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. Refer to chapter 6 for additional information.
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.

1.1.3 Description of the EntelliPro ES Motor Control Module
The EntelliPro ES is used in conjunction with CTs in branch-drawout systems. This system consists of LEDs, fuses,
contactors, and additional components required for the control and switching of the branch. The EntelliPro ES
includes the following input/output capabilities:
Seven to sixteen inputs, depending on the catalog type
Three to eight outputs, depending on the catalog type
The following additional functions are available:
Ov
erload
protection
Thermistor protection
4–20 mA output sensing
EntelliPro ES alarm modules configurable for fault (trip) or warning (alarm)
Eleven predefined starter types
Six predefined controls
Start inhibits
Restart timer
Number of starts
Number of contactor closures (each relay has its own counter)
Operating hours
Non-operating hours
Counters for overload, ground fault, and thermistor faults
Time stamp event
Time stamp analog value
The thermal model uses motor protection curves according to IEC 60947 (IEC Class 5 to 40) and incorporates hot/cold
biasing, unbalance biasing, and exponential cooling.
Figure 1-1 shows an example of a single-line system for EntelliPro ES3 and ES5.

would set the FLA range from 52.5 amps (315/6) to 315 amps. So, 77 amps could be selected.
77 amp example is to use an EntelliPro CT 630 with two primary turns. The nominal CT current = 630 / 2 = 315 amps. This
This case would require using multiple turns on the CT primary (see figure 1-2 and equation below). The solution to the
would result in the lowest FLA setting of 630/6=105 amps, which is too large for this application.
when trying to protect the motor load level at 77 amps, the EntelliPro CT 64 is too small. Considering the EntelliPro CT 630
There may be cases where the available transformer types have inappropriate ranges for the application. For example,
increments.
EntelliPro CT 64 transformer is chosen, the FLA setting can be configured from 64/6=10.7 amps to 64 amps in 0.1 amp
Use of the appropriate transformer will allow the FLA setting to be configured in the range of CT/6 to CT. For example , if the

There are three items that must be considered when configuring the motor load level of the EntelliPro ES. The items to

Range...............................................................................................8A CT: 1.34–8.0A (10 x CT)
Motor rated current X is 32 A and motor inrush current is 9X, that is 288 A. EntelliPro CT 32 must not be used in ATEX area.
Motor rated current X is 25 A and motor inrush current is 9X, that is 225 A. EntelliPro CT 32 can be used in ATEX area.
Use EntelliPro CT 64 in ATEX area.
Motor rated current X is 32 A and motor inrush current is 7X, that is 224 A. EntelliPro CT 32 can be used in ATEX area.
Example
32A CT: 5.30–32A (10 x CT)
64A CT: 10.6–64A (10 x CT)
630A CT: 105–630A (10 x CT)

Accuracy...................................................................................with external CT: ±5% / direct: ±2%
accuracy. If motor protection up to 10 *Ict is desired , the nominal current must be derated per the table below.
The range can be enlarged by feeding multiple primary loops. refer to section 1.1.5.
Table below shows the nominal motor current range that the EntelliPro CTs can be used.
Table 1-2: EntelliPro ES CT types primary current ranges and accuracy
CAUTION: The overcurrent range above 8*Ict cannot be used to protect motors in explosive areas, due to decrease
