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 T 4002, the operator
should ensure that the 220V 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.
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 MFA I 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
T 4002 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 MFA - (see 4.7 page
12/13).
Operation with load lifting magnet:
First place the magnet on the
material and then switch it on.
Swivel the magnet back in a
switched-off state.
