2.3
Mechanical features
The mechanical features described in this chapter are
standard provided on this generator set. For all other
mechanical features, see chapter “Overview of the
mechanical options” on page 76.
2.3.1
Engine and alternator
The alternator is driven by a fluid-cooled diesel
engine. The engine’s power is transmitted through a
direct disc coupling.
The generator set houses a single bearing alternator
with a dedicated voltage regulator.
The synchronous brushless alternator has Class H
rotor and stator windings in an IP21 housing.
2.3.2
Cooling system
The engine is provided with a water cooler. The
cooling air is generated by a fan, driven by the engine.
2.3.3
Safety devices
The engine is equipped with low oil pressure and high
coolant temperature shut-down switches.
2.3.4
Bodywork
The alternator, the engine, the cooling system, etc. are
enclosed in a sound-insulated galvanized bodywork
that can be opened by means of side doors (and
service panels).
The generator set can be lifted by using the lifting eye
integrated in the bodywork (roof). To be able to lift
the QES 60 by means of a forklift, rectangular slots
are provided in the frame.
The earthing rod, connected to the generator set’s
earth terminal is located inside the generator set
behind the alternator.
2.3.5
Control panel
The control panel grouping controller, fuel gauge, and
control switch, is placed at the rear end of the right
side of the generator set.
2.3.6
Data plate and serial number
The generator set is furnished with a data plate
showing the product code, the unit number and the
power output (see chapter “Data plate” on page 108).
The serial number is located at the front end of the
right side of the frame.
2.3.7
Drain plugs and filler caps
The drain holes for the engine oil, the coolant and the
plug for the fuel, are located and labelled on the
frame. The fuel drain plug is located at the rear side,
the others at the service side.
The drain flexible for engine oil can be brought to the
outside of the generator set through the drain hole.
The filler cap for the engine coolant is accessible via
an opening in the roof. The fuel filler cap is located in
the side panel.
2.3.8
Rustproof plastic fuel tank
To store fuel, which is classified as a hazardous
product, the QES Jd generator sets are provided with
a rustproof plastic fuel tank.
To extend the generator set autonomy, an optional
external fuel tank can be installed near the generator
set. See section “External fuel tank connection (with/
without quick couplings)” on page 76.
Also, a 24-hours fuel tank can be optionally provided.
The drain hole can also be used to
guide external fuel tank
connections. When connecting an
external fuel tank, use the 3-way
valves. Refer to chapter
“
fuel tank connection (with/without
quick couplings)”.
