MOZELT T4002 - Operating Instructions

4.3 Operang instrucons
When working with the load liing magnet, the pernent
industrial safety and accident prevenon regulaons are
to be observed.
In addion, liing magnet operaon may only be
started, if the operator knows the „Safety Regulaons
Magnet Operaon“ (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
opcally perfect condion. Plugs and plug connectors
are to be examined for ghtness of t, the anchoring
device of the magnet connecng cable is to be examined
for perfect funcon.
The V-belt tension with belt drives is to be examined and,
if necessary, the belts are to be reghtened according to
regulaon.
Unless otherwise expressly stated, the diesel engine
of the mobile excavator is to be brought up to full
revoluons. The generator then runs within its operang
range. The yellow LED „Ready“ automacally appears on
the mul-funcon display MFA I in the operator‘s cab.
Switching the power supply and/or the load liing
magnet on and o 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 liing magnet. If the command is given to
switch o, then the generator automacally leads to its
demagnezaon.
During the process of demagnezing, whereby the
magnet releases its load (approx. 1 sec), no renewed
switching-on command can be given.
Switching-on of the installaon is only possible, if a load
liing magnet is aached to the system.
Switching on the magnet:
Operate the buon in the control lever 1 x.
In addion to the yellow LED „Ready“, the green LED
„Power on“ lights up in the mul-funcon display.
Switching o the magnet:
Operate the same buon in the control lever again only
1 x.
The already illuminated green LED „Power on“ now goes
out and a red LED with „Power o“ lights up. Aer the
load has been dropped, this goes out automacally.
The permanently illuminated LED „Ready“ during the
shiing 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 eliminaon of such disturbances are
explained using gurave illustraons and texts under
- Breakdown indicators on the MFA - (see 4.7 page
12/13).
Operaon with load liing magnet:
First place the magnet on the
material and then switch it on.
Swivel the magnet back in a
switched-o state.
