3.5 Other connectors
3.5.1 J203 (Power supply)
J203 connector is the power supply connector of the device. Connect a DC source having a
voltage value between 7 and 32 Vdc. The negative terminal (GND) should be connected to
the protective ground. For application that requires isolation between GND and protection
ground, ask SICES for the rated condition.
3.5.2 J209 (RS232)
J209 connector is used to interface an external device equipped by a RS232 interface for
data communication. A PSTN or GSM modem can be directly connected to this terminal.
For more information about related functions and protocols, please refer to the EAAS0108xx
document.

4. Programming remarks
The board programming is a special function that can be carried out only when the engine is
dead. To gain access to these functions, it is required to press the VIEW key while the keylock
selector is in OFF/RESET-PROGRAM position.
Once in programming mode, it is no possible to control the engine and the generator.
If a menu list is show, using START and STOP keys, it will be possible to scroll the list to
select the required menu item. Press MODE to enter the selected menu.
If a parameter is show, using START and STOP keys, it will be possible to scroll the
parameter list to select the required one. To go back up to the menu list, press the VIEW
key.
The parameter value is enclosed in square brackets such as:
[400]
To modify the value, press MODE key, brackets will start to flash: using START and STOP
keys will be possible to change the value. Then press MODE to confirm the changing or
VIEW to abort it.
Each parameter page is identified by means a three digit code that is consistent in all the
configured language.

4.1 Access codes
Program access can be restricted by means a password. There are 3 different access levels
and passwords:
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, are 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 VIEW (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. EAAM013301I.doc
DST4400 Operating Manual - 28/01/2005 - pag. 11
In case of forgotten password, only knowing password of greater level is possible to rescue
the access level. Otherwise and in case of lost MAKER password the board should be
returned to the factory to reset password level.
4.2 How to modify string parameters
Some parameters require text input or modify.
In these cases, pressing MODE 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 KR/KG key, it is possible to select the character to be changed. Then
use the START and STOP keys to scroll allowable values and select the needed one.
Repeat the operation for all the characters that must be modified.
If the string has more than 14 characters, left or right (or both) arrows will be displayed. In
this case, if the cursor selects the last character before the arrow, pressing KR/KG will scroll
the text of one character to show the next one.
MODE confirms the changes and VIEW aborts.
4.3 Direct access to the last used programming page
It is possible to directly access the last used page. If the VIEW key is pressed for about 4
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 VIEW it is possible to
go up through 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 or if
the key switch is move in MAN or AUTO position.
4.4 Protection and alarm parameters
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.EAAM013301I.doc

5. Other functions
5.1 Peak archive
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.
It can be cleared only by serial port.
When the archive is cleared, it records the first measures until greater values are obtained.
5.2 Real time clock
The device has an internal real time clock calendar.
There are two different type of RTCs; the board can be equipped either with one or the
other.
• Software RTC
• Hardware RTC
The first type is supplied as standard for all the DST4400 boards. It lacks of backup supply,
thus every time the supply is disconnected, it will stop and it will lost the date and time.
The second type is supplied as option and has an internal rechargeable backup supply
source that let the RTC work for more than 2 days.
If the key-lock is in OFF/RESET position, the display shows the date and time. At the top
right of the display the message SW identifies the standard supplied RTC. The message HW
identifies the installed hardware RTC option. EAAM013301I.doc

6. Special settings
6.1 Language selection
DST4400 board can shows text strings in different languages.
To select a different language, supply the board while pressing (at the same time) the
pushbuttons START and STOP. Keep them pressed until the following screen is shown:
Special Function
Func: [LANGUAGE]
Press MODE and use scroll keys, if needed, to select LANGUAGE. Press MODE once
again. If [LANGUAGE] is already shown, press MODE twice.
At this point board will require the password.
If the keyed password is correct, a page that allows selecting the operating language will be
shown. To make effective the new language switch off and on the board.
The value required for this password is 1.
6.2 Fuel level sensor calibration
Before start the calibration procedure, connect the sensor that must be mounted in a way
that let the floater be manually operated.
Supply the board while pressing (at the same time) the pushbuttons START and STOP.
Keep them pressed until the following screen is shown:
Special Function
Func: [LANGUAGE]
Press MODE and use scroll keys, if needed, to select [FUEL LEV]. Press MODE once
again.
At this point board will require the password.
If the keyed password is correct, a page that shows the current measured fuel level will be
shown. To calibrate the sensor, follow displayed instructions.
The value required for this password is 135.
Follow the instruction that display will shown.
6.3 Counter clearing
By this procedure, it is possible to clear the following counter:
• Active and reactive counter
• Start counter
• Clearable engine hour counter
Supply the board while pressing (at the same time) the pushbuttons START and STOP.
Keep them pressed until the following screen is shown: EAAM013301I.doc
