1. INTRODUCTION

1.1. Description

y EVRC2A with the microprocessor-based digital control technology is designed to provide protective coordination and fault clearance of distribution systems for the continuous best quality of electric service.

y Remote monitoring and control can be provided by RTU(Remote Terminal Unit - Option)

which fundamentally installed. y In order to perform the protection function, line voltage and current signal filtered with

analog filter and digital DFT full-cosin filter is used. y EVRC2A provides protection, control, and monitoring functions with both local and remote.

It also displays the present trip/alarm conditions, and measured system parameters. y Recording of past trip, alarm or control events, maximum demand levels, and energy

metering is also performed. y Users can operate Close and Trip, and also control EVRC2A with key buttons on the user

interface panel; Protection Enabled, Ground Enabled, SEF Enabled, Reclose Enabled, Control Locked, Remote enabled, Alternate-settings, Program 1, Program 2, Hot line tag.

y Users can manage the Recloser interface software using a portable PC for modification of

settings, acquisition of event data, and management of operation history. y EVRC2A contains many T-C characteristic curves developed by IEEE C37.112, IEC255-3,

McGraw Edison, and KEPCO to provide fully protective coordination for the continuous best quality of electric distribution. Users can select any time of current curve simply by programming and modifying.

5.2. Communication

5.2.1. Overview EVRC2A has four ports for communication. The EVRC2A has the front panel RS232 port, the side panel RS232 port, the side panel RS485 port(or RS232 port) and the side panel Ethernet port.

Communication port settings are available as follows in Table 5-1. Communication Ports setting of EVRC2A. Table 5-1. Communication Ports setting of EVRC2A

Port Type Speed Parity bit Data bit Stop bit Location

PORT1 RS-232 57600 bps No parity 8 1 User Interface Front Panel

PORT2 RS-232 1200 - 19200 bps No parity 8 1 User Interface Side Panel

PORT3 RS-485 or RS-232

1200 - 19200 bps No parity 8 1 User Interface Side Panel

PORT4 RJ45 10BASE-T/100BASE-T User Interface Side Panel

PORT1(RS232) A port to interface with Interface Software.

PORT2(RS232) Option The Port2 is a port for a serial communication for MODBUS, DNP3.0 or IEC60870-5-101 protocol. A user can select the protocol and configure the Port2 for the selected protocol by changing baud rate and/or other settings for the Port2.

PORT3(RS485 or RS232) Option The Port3 is a port for a serial communication for MODBUS, DNP3.0 or IEC60870-5-101 protocol. A user can select the protocol and configure the Port3 for the selected protocol by changing baud rate and/or other settings for the Port3. The Port3 type of EVRC2A-N is a fixed RS485 port. However, the Port3 type of EVRC2A can be selected as RS485 or RS232 by a user. In order to use RS485 port for EVRC2A, the Pin4 and Pin5 of RS485 should be connected.



PORT4(RJ-45) Option The Port4 is a Ethernet port for TCP/IP communication (10 BASE-T /100 BASE-T speed) for Modbus, IEC60870-5-104 or DNP3.0 Protocol. A user can select the protocol and configure the Port4 for the selected protocol by changing its settings.

NOTE: From EVRC2A version 5.30, if a setting related with communication is changed and

then saved, the changed setting is applied after rebooting. During IEC60870-5-104 or DNP3.0 communication through Port2, Port3 or Port 4, a user can connect with the Interface Software ETIMS(ENTEC Integration Management Software) and use it.

Please refer to DNP3.0 Protocol Technical Manual, MODBUS Protocol Technical Manual or IEC60870-5-101/-104 Protocol Technical Manual for more information about setting for each protocol.
