User’s Manual 5
The board DST4600A, included into a special electric switchboard, is able to control the
automatic intervention of a generator set, to monitor it during the operation and to keep it in
the best possible conditions while inactive, in order to assure a quick and safe intervention in
the event of power failure. It works with both three- and single-phase systems.
Throughout this document the word “BLOCK” is used to indicate an alarm that makes
generation function impossible and causes the automatic generator shutdown with the
emergency procedure (without cooling cycle).
The word “DEACTIVATION” is used to indicate an alarm that makes generation function
impossible and causes the automatic generator shutdown with the normal procedure (with
cooling cycle).
The word “ALARM” is used to indicate a warning that requires an operator action but doesn’t
require the automatic generator shutdown.
Throughout this document the words “SOFTWARE” and “FIRMWARE are used as
synonymous if they are referred to the board firmware.
Software code is reported in short format on the board back panel. It is in the form xx.yy.uu,
where xx is the firmware short identified code, yy is the major version number and uu is the
minor version number.
The complete SW identification number for the standard DST4600A is
EB0220008yyuu
reported in back panel as (for example)
8.00.22
.
The complete SW identification number for the DST4600A/P is
EB0220012yyuu
reported in
back panel as (for example)
12.05.22
.
The complete SW identification number for the DST4600A for asynchronous engines is
EB0220029yyuu
reported in back panel as (for example)
29.07.39
.
The minor version is consistent between the two types of software (
uu
field is kept aligned).
The major version for the DST4600A/P is increased by
5
respect the standard version.
The major version for the DST4600A for asynchronous engines is increased by 7 respect the
standard version.
Thus the SWs
08.00.39
,
12.05.39 and 29.07.39
share the same main features and functions.
In this document a vertical bar on the right margin or a gray background indicates that the
chapter or the paragraph has been amended with respect to the last document’s version.
This manual is valid starting from SW
00.38
release; for previous SW release, please check
manual version 09 or previous. Otherwise use this version very carefully checking document
version notes on page ii.
If the SW version number is greater than this, this manual maybe nevertheless consistent;
please in case check for new document release.
