Range of Application
The MOZELT power supply system with synchronous
generator is designed to supply and activate load lifting
magnets on mobile excavators.
At present it is available with the output sizes 13, 20 and
30 kW.
Due to the duty rating of 100% (ED), the generators are
the optimal solution for loading and handling in the
industrial scrap metal industry.
The maintenance-free and compactly designed generator
system is powered by the diesel engine of the excavator
or the hydraulic system.

General information
MOZELT does not take any liability for the consequences
resulting from inappropriate, negligent or incorrect
installation or operation of the synchronous generator
with integrated electronics.
The conditions of guarantee of MOZELT in the valid
version at the time of purchase shall apply for the
equipment.
The content of the present manual is considered correct
at the time of printing for the indicated generator
version. MOZELT reserves the right to make changes
which represent a technical advantage.
Any change to the generators which is not performed by
us, including the installation of additional devices, can
lead to a change of the technical specification and the
content of the documentation and manual and therefore
leads to an exclusion of our liability, also from the
guarantee.
CAUTION

CAUTION
CAUTION
The rated speed of a generator of the
CG 4-series is around 3000 rpm*.
In this connection, the range from
2700 rpm to 3400 rpm is to be
regarded as the tolerance range.
It is particularly important that the
rotational speed remains constant
and no fluctuations occur!
The most important operating and switching states
are indicated in a multi-function display (MFD) in the
operator‘s cab.
1.4
Function mode
The transformation of brushless three-phase voltage into
DC voltage in the generator and its contactless delivery
after activating the generator provides the operator with
comfort and the highest safety.
The generator CG 4 is practically maintenance-free. The
abolition of contactors or relay circuits in the external
electrical plant area, as well as the absence of adjustment
buttons or potentiometers, protects this installation
system against faulty operation.
Important!
The electronic modules are equipped
with electrostatically sensitive CMOS
and MOS components.
It is absolutely necessary to observe the following
instructions since otherwise these switching circuits
can be destroyed.
• For servicing work, first equipotential bonding (static
charging) is to be ensured between electronic modules,
tools, measuring devices and personnel.
• Grasp electronic modules by the edges only, do not
touch components and their connections.
