1. Introduction
1.1. General
The REM 543 rotating machine terminal is part of the PYRAMID®substation automa-
tion system for Distribution Automation and extends the functionality and flexibility of
the concept further. This is possible due to the modern technology applied both in hard-
ware and software solutions.
Increased performance is achieved by utilizing the multiprocessor architecture. Digital
signal processing combined with a powerful CPU and distributed I/O handling facili-
tates parallel operations and improves response times and accuracy. The MMI including
an LCD display with different views makes the local use of the REM 543 rotating
machine terminal safe and easy. The MMI instructs the user how to proceed.

3. Instructions
3.1. Application
The REM 543 rotating machine terminals (referred to as "machine terminals" further
on) are designed to be used as a main protective system of generator and generator-
transformer units in small and medium-power diesel, hydroelectric and steam power
plants, among others. Protection of large and/or important MV synchronous and asyn-
chronous motors used e.g. in pumps, mills and crushers during start-up and normal run
forms another application area.
The functionality of REM 543 protection terminals is based on application-specific
libraries for protection, control, measurement, condition monitoring and communica-
tion. Each library includes a combination of specific function blocks, e.g. for protection.
Compared to the traditional use of separate products, the combination of libraries pro-
vides cost-effective solutions. Application-specific libraries together with the relay con-
figuration (IEC 1131 standard) allow the REM 543 protection terminals to be easily
adapted to different kinds of applications.
By means of the graphic MMI display, the control functions in the machine terminal
indicate the status of disconnectors or circuit breakers locally. Further, the machine ter-
minal allows status information from the circuit breakers and the disconnectors to be
transmitted to the remote control system. Controllable objects, such as CBs, can be
opened and closed over the remote control system. The status information and the con-
trol signals are transmitted over the serial bus. Local control is also possible via the
push-buttons on the front panel of the machine terminal.
The protection functions of REM 543 are designed for selective short-circuit and earth-
fault protection of rotating machines. Further, unlike most other power system compo-
nents, rotating machines also need protection against abnormal operating conditions
such as overcurrent, unbalanced load, overtemperature, overvoltage, underexcitation,
over- and underfrequency and generator motoring. Furthermore, stall protection and
cumulative start-up counter are provided for motor protection start-up supervision.
The REM 543 terminal measures three phase currents and three phase-to-phase volt-
ages, neutral current, residual voltage, frequency and power factors. Active and reactive
power is calculated from measured currents and voltages. Energy can be calculated on
the basis of the measured power. The measured values can be indicated locally and
remotely as scaled primary values.
In addition to protection, measurement, control and condition monitoring functions, the
machine terminals are provided with a large amount of PLC functions allowing several
automation and sequence logic functions needed for substation automation to be inte-
grated into one unit. The data communication properties include SPA bus or LON®*)
bus communication with higher-level equipment. Further, LON communication,
together with PLC functions, minimizes the need of hardwiring between the protection
terminals.
*) LON is a trademark of Echelon Corporation registered in the United States and other countries.

3.2. Requirements
If the environmental conditions differ from those specified in section "Technical data",
as to temperature and humidity, or if the atmosphere around the machine terminal con-
tains chemically active gases or dust, the terminal should be visually inspected in asso-
ciation with the secondary testing. The visual inspection should focus on:
• Signs of mechanical damage to the machine terminal case and terminals
• Dust inside the machine terminal cover or case; remove carefully with compressed
air
• Signs of corrosion on terminals, on the case or inside the machine terminal
For information about the maintenance of machine terminals, refer to section "Service".
Note! Protection relays are measuring instruments and should be handled with care and
protected against moisture and mechanical stress, especially during transport.

3.3. Configuration
The REM 543 machine terminals are adapted to specific applications by using the Relay
Configuration Tool included in the CAP 505 Tool Box. The tool is used for configuring
the basic terminal, protection and logic function blocks, control and measurement func-
tions, timers and other functional elements included in a logic functions library (refer to
section “Relay configuration”).
The MIMIC picture, alarm texts and LED indicators are configured with the Relay
Mimic Editor (refer to section “MIMIC configuration”).
The configuration of LON network is described in section “LON network configura-
tion”. If LON communication is used without LON inputs and outputs (network varia-
bles), the section about LON network configuration is unnecessary.
The configuration procedure starts by configuring the functions of protection, control,
condition monitoring, measurement and logics.
For more detailed information about the configuration, refer to the tool-specific manu-
als and the manual “Configuration Guideline” for RE_ 54_.

4. Technical Description
4.1. Functional description
4.1.1. Functions of the machine terminal
The functions of the REM 543 machine terminal are categorized as:
• protection functions
• measurement functions
• control functions
• condition monitoring functions
• communication functions
• standard functions
4.1.1.1. Libraries
The function blocks available for the REM 543 machine terminal are grouped into
application-specific libraries. There are libraries available for each function category,
e.g. protection libraries, measurement libraries and control libraries. One machine ter-
minal can be purchased with one library of each kind.
Please consult your relay supplier for further information regarding libraries available
for the REM 543 machine terminals.
4.1.1.2. Protection functions
Protection is one of the most important functions of the REM 543 machine terminal.
The protection function blocks (e.g. NOC3Low) are independent of each other and have
their own setting groups, data recording, etc. As an example, the non-directional over-
current protection includes the three stages NOC3Low, NOC3High and NOC3Inst, each
with independent protection functions.
Either Rogowski coils or conventional current transformers can be used for protection
functions based on current measurement (overcurrent). Correspondingly, either voltage
dividers or voltage transformers are used for protection functions based on voltage
measurement (overvoltage).
The protection function blocks are documented on the CD-ROM “Technical Descrip-
tions of Functions” (1MRS750889-MCD).

4.1.1.7. Communication
The REM 543 machine terminal provides the SPA and LON serial communication pro-
tocols.
In a customer-specific machine terminal configuration, special events can be generated
with the EVENT230 event function. EVENT230 is documented on the CD-ROM
“Technical descriptions of Functions” (1MRS750889-MCD).
For more information about communication in the REM 543 machine terminal, refer to
section “Serial communication”.
4.1.2. Configuration
4.1.2.1. Relay configuration
The Relay Configuration Tool is based on the standard IEC 1131-3. The standard
defines the programming language used for relay configuration. The programmable sys-
tem of REM 543 machine terminals allows the output contacts to be operated in accord-
ance with the state of the logic inputs and the outputs of protection, control,
measurement and condition monitoring functions. The PLC functions (e.g. interlocking
and alarm logic) are programmed with Boolean functions, timers, counters, comparators
and flip-flops. The program is written in a function block diagram language by using the
configuration software.
Fig. 4.1.2.1.-1. Example of a machine terminal configuration with the Relay Configura-
tion Tool.

Page 18
REM 543 Protection,
Monitoring and Control Technical Reference Manual Part 1, General
ABB Network Partner
Detailed information about the Relay Configuration Tool is given in the two manuals
for the tool (refer to section “References”).
4.1.2.2. MIMIC configuration
The MIMIC, a picture on the graphic LCD, is designed with the Relay Mimic Editor. In
addition, the editor is used to define the eight programmable LED indicators and the
corresponding alarm texts on the front panel, as well as the alarm modes.
The MIMIC picture may include a single-line diagram, measured values with units, free
texts, etc. The object status indicators (open, closed, undefined) are selected from a
library or drawn according to the customer's requirements. Note that the operation of the
objects themselves is determined by means of the Relay Configuration Tool.
Fig. 4.1.2.2.-1. MIMIC configuration with the Relay Mimic Editor.
All the eight alarm function blocks can be configured in the same alarm view in the
Relay Mimic Editor by defining the ON and OFF state texts and LED colours. Three
colours can be used to indicate the ON and OFF state. The three basic alarm modes
available are:
• non-latched
• latched-steady
• latched blinking
The first line of the alarm view defines the options for the MMIALAR1 function block,
the second line the options for MMIALAR2 and so on.

Interlocking LED texts can also be defined in the same alarm view, but the interlocking
LED colours cannot be changed. An interlocking LED has two special modes, the nor-
mal state of the LED being inactive. The first mode, i.e. a yellow steady lit LED, visual-
izes an interlocking action (operation failed due to interlocking), whereas the second
mode, a red blinking LED, indicates that the interlocking bypass mode (control test
mode) is on.
Fig. 4.1.2.2.-2. Alarm channel configuration.
For more information about the use of the editor, refer to the Relay Mimic Editor man-
ual.
4.1.2.3. LON network configuration
The LON Network Tool is used for binding network variables between RED 500 pro-
tection terminals. Typically, LON is used for transferring status data between the protec-
tion terminals for interlocking sequences running in each unit, see figure below.

locking.
For more information about the use of the tool, refer to the Lon Network Tool - Soft-
ware Manual.
4.1.2.4. Rated frequency
The rated frequency of the relay is set via a dialogue box in the configuration tool. The
set rated frequency can be read via the global control parameter "Rated frequency" of
the relay.
4.1.3. Parameterization
To ensure that a protection function block protects the machine in the desired manner,
the default values of parameters are to be checked and properly set before taking the
function block into use.
The parameters can be set either locally over the MMI or externally via the serial com-
munication.
4.1.3.1. Local parameterization
When the parameters are set locally via the MMI, the setting parameters can be chosen
from the hierarchical menu structure. The desired language for parameter description
can also be selected. Detailed information concerning setting and navigation is found in
the RE_ 54_ Operator’s manual (1MRS750500-MUM).
