1.2
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.
To prevent accidents, before using or servicing the machine you should read, understand and
observe the precautions and warnings in this manual.
This manual contains the following indications:
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 these
precautions can cause serious damage to property and/or injury to persons.
ATTENTION! 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 includes useful information
for the development of the operation or procedures clarifications.

EAAM057608EN GC250 Technical Manual 13
1.3
For the appropriate use of this manual it is required knowledge of the use and of the
installation of generator groups.
WARNING!!!
Every intervention must be carried out by skilled personnel. There are dangerous voltages
on the terminals of the device; before carrying out any operation on them, make sure to open
the mains and genset circuit breakers or to open the related fuses.
Do not remove or change any connection when the genset is running.
Do not disconnect for any reason the terminals of the current transformers (CT)
Wrong operations on the 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 and it is therefore
impossible to describe all their possible combinations and effects.
In this document, there isn’t a detailed description of all the programming parameters: to this
purpose, see documents [1]; these documents are to be considered as part of this manual.
The devices are supplied with a generic “default” configuration; it is at the installer’s
care 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 therefore differ from those present in your device.
1.4
Although most of the parameters and features can be accessed and configured by directly
operating on the device, some particular features or configurations, due to their nature,
can only be set or changed through the PC program SICES Board Programmer3
(hereinafter called “BoardPrg3”), which can be downloaded for free after registration on the
SICES Srl website www.sices.eu www.sices.eu and www.sicesbrasil.com.br/
It simplifies a lot the configuration of the device and its use is strongly suggested. It also allows
you to save the current configuration of the device on a file and to reuse it on other identical
devices,
The program also allows the configuration, saving or loading of the characteristic curves of
non standard analogue sensors with resistive or live output.
BoardPrg3 is usable on every SICES device; the connection to the PC is only possible via
USB serial port; by connecting the USB port to the PC, the device automatically turns on and
it is therefore possible to modify the parameters without other supply sources. For the use of
the program, refer to the document [2].
1.5
In this document, the word “ALARM” is used to indicate a fault that makes the genset
operation impossible and causes the automatic and immediate turning off of the engine with
emergency procedure (without cooling period).

14 GC250 Technical Manual EAAM057608EN
The word “DEACTIVATION” is used to indicate a fault that makes the genset operation
impossible and causes the automatic and immediate turning off of the engine with standard
procedure (with cooling period). The controller immediately opens the GCB circuit breaker
when this kind of fault arises.
The word “WARNING” is used to indicate a fault that requires an operator action but doesn’t
require the automatic shut-down of the genset.
The codes that identify functions for input, output, status or other functions are preceded by
the following acronyms:
DIF (“Digital Input Function”): the following is a code for the configuration of the digital inputs.
DOF (“Digital Output Function”): the following is a code for the configuration of the digital
outputs.
AIF (“ANALOGUE Input Function”): the following is a code for the configuration of the
ANALOGUE inputs.
AOF (“ANALOGUE Output Function”): the following is a code for the configuration of the
ANALOGUE outputs.
AVF (“ANALOGUE Virtual Function”): the following is a code for the configuration of the virtual
ANALOGUE inputs.
EVT (“Event”): the following is an event code
ST (“Status”): the following code shows the status of a dimension or a condition of the device
or of one of its functions.
AL (“Event”): the following is an anomaly code.
1.6
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.
1.7
Several parts of this manual refer to the controller's software revisions. These revisions are
marked with the assigned SICES code (shown on the rear panel of the controller). The format
of the code is: EB0250256XXYY, where “XX” is the main version and “YY” is the minor version.
Thus, the code EB02502560100 refers to the controller software release "1.00". The software
revision is also displayed on page “S.04” of the LCD display.
The software code available at the release date is:
▪EB0250256xxyy GC250.

4.1
The device has to be mounted permanently on a panel. The rear panel of the device must be
accessible only by keys or tools and only by authorized personnel for maintenance operations.
It must be impossible to remove the controller without tools. The electric control panel has to
guarantee an adequate protection against bad weather.
The mounting dimensions for the installation are 118x92mm. The mounting is carried out by
four hooks with screws: once the device is positioned, insert the hooks in the holes on the
sides and tighten the screws. Pay attention not to tighten excessively the screws in order not
to damage the hook on the device.
WARNING !: Operating temperature within the panel may vary between -30 ° C and + 70 ° C;
The outdoor operating temperature (ambient) may vary between -30 ° C and + 60 ° C.
4.2
Due to the high voltages connected to the measurement circuits of the controller, all
conductive parts of the electrical panel should be connected to the protective earthing
through permanent connections.
The installation of an overcurrent protection device is required for each phase of the mains
and generator voltage inputs. You can use 1A fuses.
The section of the protective earthing conductor should be at least equal to the section of
cables used to wire mains or generator voltage to the control panel. In addition, it must comply
with the limit value of the overcurrent protection used.
For CAT.III applications, the maximum phase-to-neutral voltage allowed is 300Vac, while the
phase-to-phase voltage is 520Vac. The maximum voltage related to the protective earthing is
300 Vac.
The device can operate in CAT.III only if the supply minus terminal of the device and the
neutral terminal of the generator are connected to the protective earth.
