NOTE: Before installing the device, carefully read par. 8.
NOTA: Before using the device, carefully read this operating manual.
DST4600A board, operating in 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.
Please refer to SICES document EAAM008800 (or following versions) for programming and
default values.
Throughout this document the word BLOCK is used to indicate an alarm that makes generation
function impossible and causes immediate generator shutdown.
The word DISABLE is used to indicate an alarm that makes generation function impossible
and causes the automatic generator shutdown after a proper cooling down cycle.
The word WARNING 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 version is reported in a format like: EB0220040xxyy, where xx is the major
version number and yy is the minor version number. Thus code EB02200400001 refers to
00.01 software release.
For DST4601 boards there are two different SW types:
EB0220040xxyy or EB0220073xxyy or EB0220082xxyy: for standard boards
EB0220057zzyy or EB0220074xxyy or EB0220083xxyy: for boards for parallel application
(DST4601/P).
In this document a vertical bar on the right margin indicates that the chapter or the paragraph
has been emended respect to the last document’s version.
A gray background highlights changes in table’s fields.

Each programming page, used for input/modify a variable value, contains a 3-digit code that
is useful to identify the variable across different language text.
Each menu or page shows, on top right of the display, a number pair. The first one is used to
identify the current page or the selected menu; the second one shows how many items are in
the present menu/list.
Please refer to SICES document EAAM008800 (or following versions) for programming and
default values.
Program access can be restricted by means a password. There are 3 different access level
and password:
1. Maker
2. System (installer)
3. User.
First page of SYSTEM menu (000-Access code) let the user input password, if at least one
of the three passwords is different from 0.
If any password is set to 0, it is not assigned and not required.
As USER it is possible to modify only the User Password.
As INSTALLER it is possible to modify the User and the System Password.
As MAKER it is possible to modify all the three passwords.
Only enabled pages for the access level the operator has gained access to be shown in the
menu, included the password modify pages.
It’s possible that, after password input, menu doesn’t show all the allowed pages. In this case
press EXIT (to go to previous menu) and access again the menu, allowing the board to reload
again the menu.
The keyed access code is kept alive for a time of about 10 minute after the programming
function is ended. After this time, the code should be keyed again, if requested, to gain access
to the same level.
In case of forgotten password, only knowing password of greater level is possible to rescue
the access level. Otherwise and in case of MAKER password the board should be returned to
the factory to reset password level.
Some parameters require text input or modify.
In these cases, pressing ENTER to activate the modify function on the selected variable,
besides the square brackets flashing, it is activated an underline cursor at the first character
string position. Using horizontal scroll keys (left and right arrows), select the character to
modify then use the vertical scroll key (up and down arrows) to scroll allowable values and
select the needed one. Repeat the operation for all the characters that must be modified.
Pressing ENTER, save text and left the function, pressing EXIT the procedure is aborted and
the previous text is restored.

User’s Manual 15
It is possible to directly access the last used page. If the EXIT key is pressed for about 3
seconds, programming function is left and the displayed page is stored. When programming
is again entered, this page is shown at first (then, if required, pressing EXIT it is possible to go
up trough menus).
The same feature is obtained when programming is automatically aborted. Programming is
aborted if for about 60 seconds no operation is carried out on programming functions.
Protections and alarms are normally configurable by means dedicated variables. For quite all
these protections can be specified the delay time. Setting to 0 the delay time of a protection
or alarm function, that function is disabled.

A number and time stamp identify each record.
The number is shown in the upper right position of multifunction display together with the total
number of available records.
Consider that, when the archive is full, a new record overwrite the old one; thus identification
number may change over the time.
This archive store the highest value measured of the following quantities:
1. Total active power and relative engine temperature
2. Phase current L1 and relative power factor
3. Phase current L2 and relative power factor
4. Phase current L3 and relative power factor
5. Maximum engine temperature
6. Minimum board internal temperature
7. Maximum board internal temperature
Each record is filled with timestamp.
In order to clear the archive, press together MODE and EXIT pushbuttons for at least 5
seconds. When the command is executed, the main event log page is recalled. When the
archive is cleared, it records the first measures until greater values are encountered.

DUE TO THE HIGH VOLTAGE CONNECTED TO THE MEASURE INPUTS, THE DEVICE
ENCLOSURE MUST BE CONNECTED TO SAFETY GROUND.
For a proper use of the device, it must be mounted in a fixed way onto a panel or cabinet.
The rear panel of the device must not be accessible without the use of tools or keys.
The device must not be removable without tools.
Safety EARTH connection must be made in a fixed way by means at least one of the
dedicated terminals.
The generator and mains voltage lines connected to the measure inputs of DST4601
Controller must have an over current protection (such as fuse). The input load of the
board is about 1Mohm. A 1A protection threshold is suitable.
The safety heart connection wire must be at least equal in section as wires used to
cable mains and generator voltage lines to the board. Wire section must be conforming
to the over current protection used.
For CAT.IV operation, the negative pole of low voltage supply (GND at JH-48) must be
connected to the SAFETY EARTH. If required operation with GND isolated from SAFETY
EARTH, please ask to S.I.C.E.S. for the allowable operation condition.
For CAT.IV operation the maximum allowable phase to neutral voltage is 300Vac (520 Vac
phase to phase). Maximum allowable input voltage toward SAFETY EARTH is 300Vac.
For CAT.III operation, the maximum allowable phase to neutral voltage is 345Vac (600 Vac
phase to phase). Maximum allowable input voltage toward SAFETY EARTH is 600Vac.
For CAT.IV operation and GCB contactor supplied by generator voltage, L1 phases must be
