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.
