Intended Use; Introduction; Control Of Id Plate; Operating Principle And Characteristics Of Voltage Regulation System - Sincro SK160 Serie Manual De Uso

2. INTENDED USE

All generators are supplied with a declaration of
incorporation in accordance with European rules and
regulations as provided in final pages of this manual.
Furthermore generators are supplied on the following
basis:
• they shall be used as power generators or for related
functions;
• they shall be used in one of the following applications:
- mobile (with or without canopy - for temporary power
supplies);
- onboard (marine use); after certification
- on commercial vehicles (freight transport / cold
storage, etc.);
- on rolling track (auxiliary power);
- on industrial vehicles (earth handling, hoisting, etc.);
- stationary installation (industrial, factory / plant);
- stationary installation (residential, commercial and
light industry, house / office / hospital);
- e nergy management (cogeneration, peaks shaving);
- alternative energy schemes;
• the standard generators are designed to satisfy
"industrial" electromagnetic emission limits and
immunity standards. In the event that generators have
to comply with electromagnetic emission limitations
for residential, commercial and light industrial zones,
some additional accessories may be necessary;
• the installation wiring diagram requires that the
generator housing is connected to the earth conductor,
using an adequately sized cable with a minimum
length possible;
• the use of any spare parts that are not genuine or
not expressly authorised shall free Sincro from any
warranty liability and any responsibility concerning
conformity to regulations and relevant consequences;
• installation, aftersales assistance and maintenance
must be carried out by properly trained staff with a
knowledge of the provisions of EC directives.

3. INTRODUCTION

On delivery inspect the generator to check it has not
been damaged during transport or that no parts are
missing.

3.1 Control of ID plate

The generators can be identified by their ID plate. The
ID plate must be checked and compared with order
specifications.
The Sincro Technical Office is always available for
any clarification.
4. OPERATING PRINCIPLE AND
CHARACTERISTICS OF VOLTAGE
REGULATION SYSTEM
The BL4-U AVR (Automatic Voltage Regulator) of
SK160 series, is supplied by the auxiliary winding. AVR
acts on the exciter stator, directly controlling the field
generated by the main rotor by means of the sequence
exciter rotor - diode bridge - main rotor.
The voltage regulator controls and keeps constant the
voltage of one phase.
Alternatively, the generator can be equipped with
a digital regulator type (AVR RD2). The RD2 AVR
regulator controls and maintains constant the average
voltage of all three phases.
A frequency control progressively deactivates the
machine when the drive engine speed drops below a
pre-set, adjustable threshold, preventing over-excitation
at low operating speeds and reducing the load engage
effects on the engine.
5. GENERAL MECHANICAL AND
ELECTRICAL SPECIFICATIONS
FOR COUPLING WITH ENGINE
As an independent unit, designed to be built into a
generating set, it is impossible to apply all the signal
decals on the generator during production. These
decals, indicating a potential hazard or risk due to live
components are supplied loose and have to be applied
by the constructor of the generating set.
This generators are designed to operate at a temperature
between -20°C and 40°C and at a maximum altitude of
1000m a.s.l.
The nominal performance indicated on the plate refers
to operation within these temperature and altitude limits.
Contact Sincro Technical Office for operate outside
these parameters.

At temperatures over 40°C and/or altitudes above
1000m a.s.l. a derating should be applied (see table).
For all "CSA/UL" generators, don't consider these data
and contact the Sincro Technical Office.
The generators are fitted with an air ventilation system,
protective guards and drip-proof covers; they are not
suitable for outdoor installation unless an adequate
protective shelter is provided. When under storage,
awaiting installation or in standby, it is advisable to use
anticondensation heaters to protect the windings from
damp.
In the event of installation inside a closed housing, make
sure that the cooling air temperature for the generator
does not rise above standard.
The canopy must be constructed so that the engine
air vent in the canopy is separate from the generator
air vent, especially if the air inlet in the canopy has
to be supplied by the cooling fan. What's more, the
generator air vent should be constructed to prevent
damp from entering by fitting suitable protections. The
canopy should be designed so that there is a minimum
clearance of 50mm between the generator air vent and
any flat surface.
