Many accidents are caused by poor knowledge and the non-observance of safety regulations,

which must be observed when operating and/or servicing the machine.

Before using or servicing the machine, you should read, understand and observe the

precautions and warnings in this manual, in order to prevent accidents.

In order to identify the safety messages included in this manual, see the words listed below.

WARNING! This indication is used in the safety messages of the manual when

there are possible danger situations that may cause injuries or death if the danger is

not avoided.

This safety messages describe the normal precautions needed to avoid danger.

Ignoring this instructions may cause serious damages to things and/or people.

WARNING! This indication is used in the safety messages for dangers that, if not

avoided, may cause injuries, damages or malfunctioning.

The message can be also used only for few dangers that may cause damages to things

and/or people.

INFORMATION! This term indicates that the message provides useful information

forperforming the current operation, or for explanations or clarifications of procedures.

2 D-PRO Protection relay Technical Manual

1.3

D-PRO is a protection relay for the genset. It includes all the necessary functions to acquire

the measurements of the plant and to activate one or more outputs in order to keep the plant

safe in case of irregular values acknowledged. The system is not equipped by a multifunctional

display, but it requires the connection to the DST4602 controller for a complete use with the

visualization of the faults and the measurements of frequency, voltage, current and power of

the plant. In case of “stand-alone” use (without connection to the DST4602 controller), the D-

PRO protection relay carries out the same basic functions, but the information are displayed

through LEDs.

1.3.1

The following table shows the protections implemented:

1.4

For the appropriate use of this manual it is required knowledge of the use and of the

installation of generator groups.

WARNING!!!

Every operation must be carried out by skilled personnel. There are dangerous voltages on

the terminals of the device; before carrying out any operation on them, ensure you have

opened the mains and genset circuit breakers or removed the related fuses.

D-PRO Protection relay Technical Manual 3

Do not remove or modify any connection during the genset operation.

Do not disconnect the current transformers terminals (C.T.) for any reason.

Wrong interventions on connections can cause the disconnection of the loads from the mains

or the genset.

Please read this manual carefully before using the device.

The device uses a large number of configurable parameters; therefore, it is impossible

to describe all their possible combinations and effects.

In this document, there isn’t a detailed description of all programming parameters: to this

purpose, see [1]. These documents have to be considered as part of this manual.

The devices are supplied with a generic “default” configuration; it is the installer’s

responsibility to adjust the operating parameters to the specific application.

SICES srl carries out a great effort to improve and update its products; therefore, they are

subject to both hardware and software modifications without notice. Some of the features

described in this manual may differ from those present in your device.

1.5

IMPORTANT Both SW1 switches must stay on position OFF.

The SW1 switches allow a reserved access to special functions that usually are not included

in the normal operation of the device.

If the device is supplied with one of the two switches on ON, it does not turn on. In order

to bring the device back to the normal operation, you need to disconnect it, position the

switches on OFF and connect it again.

If the device does not turn on when supplied, check the position of the switch first.

1.5.1

The parameters and the functions can be configured or adjusted exclusively by the PC

program SICES Board Programmer3 [8] (hereinafter called “BoardPrg3”) installed on the

CD supplied together with the device and downloadable for free, after registration, on SICES

Srl websites. www.sices.eu e www.sicesbrasil.com.br.

It considerably simplifies the configuration of the device and allows the file saving of the device

configuration and its following use on other similar devices too.

The program also allows the configuration, saving or loading of the characteristic curves of

non standard analogue sensors with resistive or live output.

BoardPrg3 [8] can be used on all SICES devices; the connection to the PC can be direct via

serial RS232 or USB, or by remote via modem, serial RS845 or Ethernet. For the use of the

program, refer to the proper manual.

1.6

1.6.1

D-PRO is able to report and manage all the faulty conditions occurring during the operation of

the system. The faults are classified in two categories, according to their severity and based

on the actions D-PRO performs to manage them:

4 D-PRO Protection relay Technical Manual

•Warning. This term is used to indicate an anomaly that, under the current

circumstances, doesn’t compromise the operation of the genset: the operator should

take note of it anyway, because sooner or later it could worsen in a more serious

anomaly.

•Alarm. This term is used to indicate an anomaly that requires the stop of genset.

There are immediate risks for the genset, therefore it needs to be stopped

immediately.

1.6.2

AIF It identifies a function for the configuration of the analogue inputs (“Analogue

Input Function”). The number that follows the caption “AIF” is the code to set in

the parameter that configures the function of the desired analogue input.

AOF It identifies a function for the configuration of the analogue outputs (“Analogue

Output Function”). The number that follows the wording “AOF.” is the code to

set in the parameter that configures the function of the desired analogue output.

AVF It identifies a function for the configuration of virtual analogue inputs (“Analogue

Virtual Function”). The number that follows the wording “AVF.” is the code to

set in the parameter that configures the function of the desired analogue input.

DIF It identifies a function for the configuration of digital inputs (“Digital Input

Function”). The number that follows the caption “DIF” is the code to set in the

parameter that configures the function of the desired digital input.

DOF It identifies a function for the configuration with the digital outputs (”Digital

Output Function”). The number that follows the caption “DOF” is the code to set

in the parameter that configures the function of the desired digital output.

EVT It identifies an event in the history log. The number that follows the caption

“EVT” is the numeric code of the event.

ST It identifies a controller status (”Status”). The code the follows the caption “ST.”

indicates a status of a measurement or a condition of the device or of one of its

functions.

AL It identifies an alarm (”Alarm”). The number that follows the caption “AL.”

indicates the alarm numeric code.

1.7

In this manual, the modifications, with respect to the previous version, are signalled by a

vertical bar on the right of the paragraphs. The modifications on the fields of a table are

highlighted with a grey background.

1.8

The software revisions will be described in different part of the manual. These revisions are

referred with the SICES code assigned to it (which is reported on a label on the controller rear

side). The code format is: EB0250247XXYY, where “XX” is the major version number and “YY”

is the minor version number. Thus, the code EB02502470100 refers to the controller software

release "1.00".

INFORMATION! In the codes above, the two letters marked with YY can be replaced

by a number indicating the version. The two final letters XX can be replaced by a

progressive number indicating the product revision or option.
