2.2 Basic Safety Instructions
Basic safety instructions always apply to the safe operation of the machine and are summarized in the following
sections.
NOTICE
Failure to observe the safety instructions may endanger persons, the environment or property.
In addition to the basic safety instructions, also observe the special safety instructions listed
in the other chapters of these operating instructions as well as the machine specific safety
instructions.
2.2.1 Electric System
Always disconnect the negative battery terminal before working on the machine's electrical system.
All work on the machine’s electrical system must be carried out by trained electricians.
Touching damaged live parts can cause serious electric shock, injury or death. Damaged insulation and
electrical system components must be repaired immediately by qualified personnel.
Check electrical equipment regularly: Retighten loose connections and replace damaged lines or cables
immediately.
Only use prescribed fuses. The system could be destroyed if stronger fuses are used! Fire hazard!
Be sure to follow the correct sequence when connecting and disconnecting the battery!
oConnecting: first connect the positive terminal, then the negative terminal.
oDisconnecting: first disconnect the negative terminal, then the positive terminal.
The positive terminal must always be covered with the provided protective cover.
Avoid sparks and open flames near the battery. There is a risk of explosion!
The machine is equipped with electronic components and assemblies whose function may be affected by
electromagnetic emissions from other devices. Such affects can be hazardous to personnel if the following
precautions are not followed.
oIf electrical and electronic equipment and / or components are subsequently installed in the
vehicle with a connection to the electrical system, the user must independently verify whether
the installation causes disturbances to the vehicle electronics or other components.
oIt is important to ensure that subsequently installed electrical and electronic components meet
the requirements of the EMV - Directive 89/336/EWG in accordance with the current version
and that they bear the CE symbol.
oFor wiring and installation as well as the max. allowable power use the machine manufacturer's
installation instructions must be followed.
Never equip the machine with unauthorised work lights. The manufacturer assumes no responsibility or
liability for consequential damage to the electrical system.
Learn to operate the terminals properly.
Press the terminal keys with your fingertip. Avoid using your fingernails.
Keep the terminals and accessories in good condition.
Only clean the terminals with a soft cloth moistened with clear water or a bit of glass cleaner.

Operation

3 Operation
The "Operation" chapter contains information on the possible machine controls. It describes the individual
functions, the handling and the procedure for operating the machine using a terminal.
The components and machine functions listed in the operating instructions may differ from the machine
standard equipment and are available as optional equipment in some cases. Since these operating instructions
are general, various equipment options can be listed that are not available for your trailer. This also applies to
the images. Images, drawings and 3D illustrations in these operating instructions do not always represent the
exact machine type. However, the information which refers to the illustrations always corresponds to the
machine type in this document.
WARNING!
Failure to observe the safety instructions may result in serious injury or death.
In order to prevent accidents, the operator of the machine must read and observe the safety
instructions in the "Safety" chapter.
WARNING!
Reaching into the machine can cause crushing, shearing, cutting, severing, being caught,
entangled, pulled in and struck in the machine.
These hazards may arise when
- the unsecured tractor and the trailer unintentionally roll,
- power driven tools are not switched off,
- hydraulic functions are activated unintentionally,
- tools or machine components are in operation,
- the tractor engine is switched on inadvertently,
- raised machine components are lowered inadvertently.
All machine operations are dangerous due to possible unintentional contact with driven,
unsecured parts and raised, unsecured machine components.
Therefore the machine must be secured against unintentional rolling and starting before any
work is done on the machine, e.g. Making adjustments or correcting malfunctions.
For this, the notices and instructions in the operating instructions in section
"Commissioning" under "Securing vehicle against unintentional rolling and
starting" are to be observed.

3.1 Terminal BCT20
The hydraulic functions are operated using the BCT20 terminal. The
terminal is characterized by
- ON/OFF for terminal,
- rotary / push button,
- ergonomically arranged keys,
- back-lit membrane keypad,
- backlit display,
- freely programmable sequence control of individual functions,
- trip counter,
- a variety of functions.
Fig. 2: Terminal BCT20
Additional hydraulic functions without control block connection have no terminal functionality. Such functions
can be operated directly by the tractor control units according to the hydraulic system manual control after
coupling the supply lines to the tractor.
For this, observe the notices and instructions in the operating instructions in chapter "Functions
and Settings" in the “Hydraulics” section.
NOTICE
Protect the terminal from water.
Store the terminal in a dry room if it is not used for a long period (e.g. in winter).
Disconnect the power supply during installation and repair work. Remove all electronic
components (terminal, BSG, ISO-Gate, etc.) during welding work. Overvoltage can damage
the terminal's electronics.
3.1.1 Emergency Control
WARNING!
Danger due to moving components during emergency control!
Ensure third persons leave the vehicle danger area before using the emergency control on
the control block.
NOTICE
In case of a power failure, check the fuses in the tractor and control unit (supply line). Check
cables and connections.
Electrically controlled hydraulic valves which are used for "Emergency control" can be controlled manually.
For this, observe the notices and instructions in the operating instructions in chapter "Functions
and Settings" in the “Hydraulics” section.

Operation

3.1.2 Installing the BCT20 Terminal
NOTICE
The terminal must be mounted in the driver's field of vision and reach so that it is easy to read
and operate. It must not obstruct the view of the tractor's controls or to the surrounding area.
To install the terminal (Fig. 3 / Pos.1) proceed as follows:
Select a suitable position in the tractor cab where you would like to
mount the terminal (Fig. 3 / Pos.1).
Loosen the eyebolts (Fig. 3 / Pos.4) on the bracket (Fig. 3 / Pos.3)
on the back of the terminal (Fig. 3 / Pos.1).
Guide the rod (Fig. 3 / Pos.2) through the holes in the bracket (Fig. 3
/ Pos.3) (the rod is not included, ø22mm).
If the terminal (Fig. 3 / Pos.1) collides with the rod (Fig. 3 / Pos.2)
when moved, the position of the bracket (Fig. 3 / Pos.3) must be
adapted to the terminal (Fig. 3 / Pos.1). For this, loosen the nuts
(Fig. 3 / Pos.5), adjust the terminal (Fig. 3 / Pos.1) and retighten the
nuts (Fig. 3 / Pos.5).
Position the terminal (Fig. 3 / Pos.1) in the desired height. Ensure
that the rod (Fig. 3 / Pos.2) protrudes at least 2cm above the bracket
(Fig. 3 / Pos.3).
Fasten the terminal (Fig. 3/ Pos.1) by tightening the eyebolts (Fig. 3 /
Pos.4) on the rod (Fig. 3 / Pos.2).

3.1.3 Connecting the Terminal
WARNING!
Danger due to incorrect system and supply line connection
Incorrect connection of the supply lines can lead to considerable hazards for persons due to
machine malfunctions.
Before commissioning, check for proper supply line connection.
When connecting the supply lines, ensure that both plugs and sockets are clean and dry. Dirt
and moisture can lead to a short circuits!
Supply lines between tractor and trailer must be laid in such a way that they cannot be
rubbed, clamped, crushed, bent or rub against foreign parts during trailer movement (e.g.
cornering).
