DISPLAY AND CONTROL ELEMENTS 4
MHL360 E 4.33
4.5.7 Magnet system (optional)
The magnet system is used for handling fer-
rous materials. It is switched on or off using
the main control display. Magnetiza-
tion/demagnetization is performed using a
button on the left-hand four-way control lever.
For operation purposes, the main control dis-
play offers the option of a normal magnet sys-
tem display or a comfort magnet system dis-
play. Which of the two displays appears de-
pends on what is selected in the display set-
tings menu. The isolation guard (ISO guard)
continually monitors the isolation resistance of
the entire magnet system (generator, elec-
tronics, cabling, magnetic plate).

Structure
The button for the magnet system is marked
with the symbol (59/1). When the ignition is
switched on, the symbol is gray; once the die-
sel engine starts, it is black. When the diesel
engine is running and button (59/1) is activat-
ed, a symbolized LED (59/2) appears. When
the magnet system is ready to operate, the
indicator (59/3) then appears. Its color indi-
cates the status of the magnetic plate.
Green: not magnetized
Yellow: magnetized
Orange: magnetized, generator speed too
low.
Blue: ISO guard function test is running
The appearance of the symbol in the indicator
(59/3) shows the current operating mode. To
change this, activate button (59/1) until the
magnet system operating mode selection
menu appears (Fig. 60). This menu allows
you to select an operating mode and shows
the current isolation resistance measurement
(60/10). If required, you can use button (60/9)
to initiate an ISO guard function test manually.
If this fails, an error message will appear.
