The complete package of manuals to a terminal is named users manual (UM). The
8V
HUVPDQXDO
consists of four different manuals:
7KH$SSOLFDWLRQ0DQXDO$0
contains descriptions, such as application and func-
tionality descriptions as well as setting calculation examples sorted per function. The
application manual should be used when designing and engineering the protection ter-
minal to find out when and for what a typical protection function could be used. The
manual should also be used when calculating settings and creating configurations.
7KH7HFKQLFDO5HIHUHQFH0DQXDO750
contains technical descriptions, such as
function blocks, logic diagrams, input and output signals, setting parameter tables and
technical data sorted per function. The technical reference manual should be used as a
technical reference during the engineering phase, installation and commissioning phase
and during the normal service phase.
7KH2SHUDWRUV0DQXDO20
contains instructions on how to operate the protection
terminal during normal service (after commissioning and before periodic maintenance
tests). The operator´s manual could be used to find out how to handle disturbances or
how to view calculated and measured network data in order to determine the reason of
a fault.
7KH,QVWDOODWLRQDQG&RPPLVVLRQLQJ0DQXDO,&0
contains instructions on how to
install and commission the protection terminal. The manual can also be used as a refer-
ence if a periodic test is performed. The manual covers procedures for mechanical and
electrical installation, energising and checking of external circuitry, setting and config-
uration as well as verifying settings and performing a directionality test. The chapters
and sections are organized in the chronological order (indicated by chapter/section
numbers) the protection terminal should be installed and commissioned.
