WELGER RP 435 MASTER E-LINK
3.2
General Information
Attention! Read and heed the operating instruction and safety instructions prior to
commission the machine. In this operating instruction all positions required for safety reasons are
marked with a warning sign. Instruct all other operators in safety instructions! The warning- and
information signs located at the machine give information for safe operation. Watch them for safety
reasons!
• It is not permissible to enter the working range of the machine or to approach the working range of
the machine as long as the electronics are supplied with power.
• Prior to any kind of assembly, adjustment and maintenance work, the control must be disconnected
from power supply: interrupt electrical connection between tractor and machine.
Moreover : Switch off power take-off shaft. Switch off tractor engine and remove ignition key.
Uncouple power take-off shaft of the machine from the drive shaft of the tractor.
• Check correct setting of all sensors regularly and check that all sensors (proximity switches) and
actors (plugs on hydraulic system, plugs on net tying unit or plugs on twine tying unit) are tightened
properly.
• Power supply of the electronics must only be switched on when the machine is to be operated. After
the end of work, the control system must immediately be disconnected from power supply: interrupt
electrical connection between tractor and machine.
• The housing of the control box is moisture-repellent. Nevertheless: in order to avoid malfunctions,
the control box must not be exposed to excessive moisture (e.g. heavy rain, splashing, steam-jet- or
high-pressure cleaning machine).
• Software- or hardware malfunction can never be totally excluded. Therefore the machine has always
to be handled so that no personal or material damages occur.
• Read the pertinent documentation before commissioning the machine. In case of difficulties in
understanding please contact the customer service department.
3.3
Instructions for fire protection
• In certain conditions the harvested crop is easily inflammable.
• Keep baler always free from crop remains or oil pollution. This note counts especially after finishing
baling.
• The present wiring of the control and of the corresponding machine must not be used for electrical
consumers other than mounted or proofed by the manufacturer. Overloading the electrical lines
leads to excessive heating.
• Always keep a working fire extinguisher within reach.
WELGER RP 435 MASTER E-LINK
7
3.4
Protection of the electronic control system
• All assembly work (connection and disconnection of sensors, valves, control box etc., replacement
of fuses) must be carried out with the power supply switched off.
• The control is designed for 12 Volt operation. Operation with other on-board power supplies is not
permissible!
• The correct polarity of the power supply of the
tractor must not be changed, otherwise the
electronic control could be damaged.
• In case of welding work on the baler:
- Do not permit welding current to flow through the control unit;
- Interrupt power supply between tractor and baler;
- Take heat generation at the welding points into account;
if necessary remove sensitive parts (cables, sensors or the like) prior to welding.
3.5
Electromagnetic compatibility (EMC)
The machine is equipped with electronic components and modules; the function of these electronic
components and modules can be influenced by electromagnetic emissions of other equipment. Such
influences can cause risks to persons, if the following safety instructions are not observed:
In case of subsequent installation of electrical and electronic equipment and/or components into the
machine, with connection to the central mains, it is the user's responsibility to check whether the
installation impairs the vehicle electronics or any other components.
Ensure above all that the electrical and electronic components subsequently installed are in
conformity with the EMC directive 89/336/EEC as amended, and that they are provided with the CE.

Standard diagnosis – Actors
Actors are e.g. electro-valves of the hydraulic system.
In the ACTOR DIAGNOSIS, the status of the actor
channels is displayed. The functions can be tested
manually (Diagnosis Manual) or automatically
(Diagnosis Automatic).
Attention, danger of injury!
Standard diagnosis may only be performed after the
machine has been stopped: Switch off tractor engine,
wait until machine has stopped, disconnect hydraulic
supply to the machine.
Note!
The number of the actors shown or of the display
pages depends on the settings in the "Setup" menu
(see chapter 6 "Setup" menu).

Net tying
Twine tying
The extended diagnosis offers a possibility of viewing
the state of sensor and actors during machine
operation.
Operation of the extended diagnosis is identical to
that of the standard diagnosis (see chapter „8.1
Standard diagnosis). In case of extended diagnosis,
however, the service personnel has exclusively the
function of an observer. Any interference in the
sequence of machine operations (e.g. starting of the
automatic actor diagnosis or switching of a selected
actor channel) will immediately stop machine
operation and thus the extended diagnosis.
Indication for extended diagnosis: the symbol
