5.2 The indicators and operating functions of the control panel
The control panel of the MLS 508 contains all the keys necessary for the expanded
handling of the system, several indicator lights and a graphic display which indicates
the current status of the system at any time.
The front of the control panel is divided into 3 main function groups:
The graphic display:
During normal operations, the 240 x 64 pixel backlit graphic display indicates the
sensor types used for the two control loops “left” and “right” along with their target
values and actual values. In the configuration menu, the display shows parameters,
notices regarding the system and instructions on the various settings.
The function keys:
The assignment of the function keys F1 to F4 (from left to right) differs depending on
the current menu.
The specific function of a key is described in the graphic display above it by means
of an abbreviation which allows a clear and simple navigation among the different
menus.

The control loops “left” and “right”:
Presently, the MLS 508 offers three separate control loops for valve actuation.
Depending on the individual application, the control loops can be operated with
different sensors and be enabled or disabled independently.
The control loops “left” and “right” are used to control the grade and slope of a tool
(e.g. a milling drum).
The operator elements of the control loops in detail:
A
MThe A/M key is used to switch
between the selected control
loop’s 2 operating modes –
manual mode and automatic
mode.
The UP/DOWN keys are used to
change the target value of the
respective control loop. In the
configuration menu, they are
used to select menu points or to
set
p
arameters.
The automatic lights indicate
which operating mode has been
chosen for a specific control loop
with the help of the A/M key (also
refer to “7.2 Definition of terms“).
Light off = manual mode
Light on = automatic mode
The sensor change key directly
accesses the menu in which the
sensor type for the specific
control loop can be selected
(also see “6.6 Sensor
selection”). In automatic mode
via this key the sensor can be
directly changed.
The valve lights indicate the
direction in which the hydraulic
cylinders of a specific control loop
have to be moved to reach the
preset target value (also refer to
“7.2 Definition of terms”).

This chapter will provide you with information on the start-up of the system, on the
setting of contrast and on sensor selection. In addition, you will find a description of
the symbols and displays used in the working window as well as instructions on how
to navigate within the configuration menu and set parameters.
6.1 Before starting-up
Before first starting-up the MLS 508 it has to be visually inspected.
Check all system components referring obvious damages, all cable connections for
securely fitted position and all sensors for secure and accurate assembly.
When starting-up the MLS 508 ensure that no persons or objects are located in the
tool’s area or the range of moving parts for the tool’s control.
6.2 Starting up the MLS 508
Switch on the supply voltage of the MLS 508. Depending on the system installation,
this can be done by turning the machine’s ignition key or by activating a separate
switch on the dashboard.
For 3 seconds the following power-on message is displayed, with the system
designation, the manufacturer’s logo and 3 information lines, which are editable in
the configuration menu (e.g. company name, machine model, driver’s name, etc.).
