18/20 Bosch Rexroth AG
RC RE 95203/11.07
• General instructions:
– Reliable operation cannot be guaranteed if samples or prototypes are used in series production machines.
– The suggested circuits do not imply any technical liability for the system on the part of Rexroth.
–
Incorrect connections could cause unexpected signals at the outputs of the controller.
– Dangerous malfunctions may result if the control electronics are opened or modified or the wiring repaired without authorization.
– In addition, the application-specific documents (connection diagrams, software descriptions, etc.) are to be observed.
– To switch off the system in emergencies, the power supply to the electronics must be disconnected with a safety switch.
The safety switch must be installed in an easily accessible position for the operator.
The system must be designed in such a way that actuating the safety switch ensures safe braking.
– System developments, installations and commissioning of electronic systems for controlling hydraulic drives must only be
carried out by trained and experienced specialists who are sufficiently familiar with the components used and with the
complete system.
– Unexpected dangers may be present at the machine during commissioning of the RC. For this reason, before commissioning
the system, you must ensure that the vehicle and the hydraulic system are in a safe condition.
Make certain that no persons are present in the danger zone of the machine.
– No components that are defective or not working properly should be used. If components fail and/or exhibit malfunction,
repairs must be carried out immediately.
– The controller RC warms up above regular ambient temperature during operation. To prevent risks due to high
temperatures, it should be attached and protected before it is touched.
– Incorrect programming of the RC may create potential sources of danger while the machine is in operation.
It is the responsibility of the machine manufacturer to determine dangers of this type in a risk assessment and to bring them
to the attention of the end user. Rexroth assumes no liability for risks of this type.
– Make sure that the controller configuration does not lead to safety-critical malfunctions of the complete system in the event
of failure or malfunction. This type of system behavior may lead to danger to life and/or cause much damage to property.
• Conventional use:
– The controller RC is designed for use in mobile working machines provided no limitations / restrictions are made to certain
application areas in this data sheet.
– Operation of the controller RC must generally occur within the operating ranges specified and released in this data sheet,
particularly with regard to voltage, temperature, vibration, shock and other described environmental influences.
Use outside of the specified and released boundary conditions may result in danger to life and/or cause damage to
components which could result in consequential damage to the complete system.
– Damages which result from improper use and/or from unauthorized, unintended interventions in the device not described
in this data sheet render all warranty and liability claims with respect to the manufacturer void.
• Notes on the installation point and position:
– Do not install the controller near parts which generate considerable heat (e.g. exhaust).
– Install the controller in such a way that the connector is pointing downwards. This ensures that any condensation water
can drain.
– A sufficiently large distance to radio systems must be maintained.
– All connectors must be unplugged from the electronics during electrical welding operations.
– The controller must not be electrostatically charged, e.g. during painting operations.
– Radio equipment and mobile telephones must not be used in the driver's cab without a suitable antenna or
near the control electronics.
– Cables/wires must be sealed individually to prevent water from entering the controller.
• Notes on transport and storage:
– Controllers must be stored in mean relative humidity of 60% at a temperature between -10°C and +30°C.
Briefly, for 100 hours, a storage temperature range of -20°C to +40°C is permissible.
– After a storage time of more than 5 years, the controller must be examined by the manufacturer before it is used.
– The controller must not be used if it has been dropped, as damage that is not visible could still affect its reliability.
