The engineering manual contains instructions on how to engineer the IEDs using the different
tools in PCM600. The manual provides instructions on how to set up a PCM600 project and
insert IEDs to the project structure. The manual also recommends a sequence for engineering
of protection and control functions, LHMI functions as well as communication engineering for
IEC 60870-5-103, IEC 61850 and DNP3.
The installation manual contains instructions on how to install the IED. The manual provides
procedures for mechanical and electrical installation. The chapters are organized in
chronological order in which the IED should be installed.
The commissioning manual contains instructions on how to commission the IED. The manual
can also be used by system engineers and maintenance personnel for assistance during the
testing phase. The manual provides procedures for checking of external circuitry and
energizing the IED, parameter setting and configuration as well as verifying settings by
secondary injection. The manual describes the process of testing an IED in a substation which
is not in service. The chapters are organized in chronological order in which the IED should be
commissioned.
The operation manual contains instructions on how to operate the IED once it has been
commissioned. The manual provides instructions for monitoring, controlling and setting the
IED. The manual also describes how to identify disturbances and how to view calculated and
measured power grid data to determine the cause of a fault.
The service manual contains instructions on how to service and maintain the IED. The manual
also provides procedures for de-energizing, de-commissioning and disposal of the IED.
The application manual contains application descriptions and setting guidelines sorted per
function. The manual can be used to find out when and for what purpose a typical protection
function can be used. The manual can also be used when calculating settings.
The technical manual contains application and functionality descriptions and lists function
blocks, logic diagrams, input and output signals, setting parameters and technical data sorted
per function. The manual can be used as a technical reference during the engineering phase,
installation and commissioning phase, and during normal service.
The communication protocol manual describes a communication protocol supported by the
IED. The manual concentrates on vendor-specific implementations.
The point list manual describes the outlook and properties of the data points specific to the
IED. The manual should be used in conjunction with the corresponding communication
protocol manual.
The service manual is not available yet.

Although warning hazards are related to personal injury, it is necessary to understand that
under certain operational conditions, operation of damaged equipment may result in
degraded process performance leading to personal injury or death. Therefore, comply fully
with all warning and caution notices.
1.4.2 Manual conventions AMU0600456 v8
Conventions used in IED manuals. A particular convention may not be used in this manual.
• Abbreviations and acronyms in this manual are spelled out in the glossary. The glossary
also contains definitions of important terms.
• Push button navigation in the LHMI menu structure is presented by using the push button
icons, for example:
To navigate between the options, use and .
• HMI menu paths are presented in bold, for example:
Select Main menu/Settings.
• LHMI messages are shown in Courier font, for example:
To save the changes in non-volatile memory, select Yes and press .
• Parameter names are shown in italics, for example:
The function can be enabled and disabled with the Operation setting.
• The ^ character in front of an input or output signal name in the function block symbol
given for a function, indicates that the user can set an own signal name in PCM600.
• The * character after an input or output signal name in the function block symbol given for
a function, indicates that the signal must be connected to another function block in the
application configuration to achieve a valid application configuration.
