The V-belt tension with belt drives is to be examined and,
if necessary, the belts are to be retightened according to
regulation.
Unless otherwise expressly stated, the diesel engine
of the mobile excavator is to be brought up to full
revolutions. The generator then runs within its operating
range. The yellow LED „Ready“ automatically appears on
the multi-function display MFD in the operator‘s cab.
Switching the power supply and/or the load lifting
magnet on and off is usually accomplished with a switch
located in the handle. Depending on the type of device,
this must be energized with a separate switch in the
control console of the mobile excavator. For this purpose
also see the notes in the manual for the mobile excavator.
If the switching-on command is given, then the generator
CG 4 connects the voltage contactless through to the load
lifting magnet. If the command is given to switch off, then
the generator automatically leads to its demagnetization.
During the process of demagnetizing, whereby the
magnet releases its load (approx. 1 sec), no renewed
switching-on command can be given.
Switching-on of the installation is only possible, if a load
lifting magnet is attached to the system.
Switching on the magnet:
Operate the button in the control lever 1 x.
In addition to the yellow LED „Ready“, the green LED
„Power on“ lights up in the multi-function display.
Switching off the magnet:
Operate the same button in the control lever again only
1 x. The already illuminated green LED „Power on“ now
goes out and a red LED with „Power off“ lights up.
After the load has been dropped, this goes out
automatically. The permanently illuminated LED „Ready“
during the shifting processes indicates that a renewed
procedure is now possible and that the power can be
switched on. Breakdowns are indicated by illuminated
red LEDs.
The meaning and elimination of such disturbances are
explained using figurative illustrations and texts under -
Breakdown indicators on the MFD -.
Make sure that ...
•
the person supervising the trial run is qualified
and competent to carry out, and supervise,
the mechanical and electrical installation.
•
the nominal values of the power generator
correspond to the operating conditions.
•
the power generator is securely fixed.
•
the power generator is adequately ventilated.
Safety measures shall be properly adhered to!

Operating instructions
When working with the load lifting magnet, the pertinent
industrial safety and accident prevention regulations are
to be observed.
In addition, lifting magnet operation may only be started,
if the operator knows the „Safety Regulations Magnet
Operation“ (see Table of Contents).
Before start-up of the power supply CG 4, the operator
should ensure that the 230V cable system is in an
optically perfect condition. Plugs and plug connectors are
to be examined for tightness of fit, the anchoring device
of the magnet connecting cable is to be examined for
perfect function.
WARNING
Before start-up, subject the complete
system to a visual inspection!
WARNING
Before start-up, check correct seating
of the V-belts!
WARNING
Connect only lifting magnets to the
system! For other electrical consumers,
operation is not allowed!
WARNING
Before start of all work on the entire
system, shut down the drive motor!
