2 Safety instructions
2.1 Symbols
2.2 Appropriate use
These symbols are used to warn against potential safety hazards or causes of
damage or provide useful information.
Hazard warning
This symbol appears in the operating instructions next to all instructions relating to
safety at work wherever a potential danger to life and limb exists.
Follow these instructions at all times and be particularly vigilant and cautious.
Pass on safety instructions to all persons entrusted with working on the product
including the power supply.
In addition, observe all general safety regulations at all times.
Warning against dangerous electrical voltage
Contact with live parts can result in immediate death. Protective covers (e.g.
covers and enclosures) marked with this sign may only be opened by qualified
electricians. Before opening, all relevant operating, control, feed or other voltages
must be disconnected.
Operating hazard for the installation
This symbol in the operating instructions indicates all warnings which, if not
complied with, may result in damage to the product.
The DRC-J joystick control system is intended to be used as an operating unit and
transmitter station for the DRC-DR and DRC-MP radio receivers. The scope of
functions is preferably designed for wireless control of crane installations, travelling
hoist units, chain and rope hoists, transfer carriages and similar applications.
The operator can position himself as required. He can control loads and movements from a safe distance. He must always select a location to ensure that all
movements of the load and the crane can be monitored and any hazardous movement can be switched off within an appropriate time. Before starting a crane movement by actuating the operating element, the operator must determine which crane
is being controlled. The display of the DRC-J joystick control unit shows the identification/crane number of the controlled crane. The radio-controlled crane must be
identified by means of the identification/crane number in a way clearly visible to the
operator.
If required, a signal must be actuated prior to a crane movement for acoustic
control.
7
DRC transmitters and receivers meet the requirements of the standards and
regulations listed in the EC conformity declaration. The specified EC conformity
declaration is an integral part of the relevant operating instructions.
Transmitters and receivers of the DRC range can be operated without any
registration or operating fee. The benefits that this provides for the user are also
utilised by some other manufacturers of devices for communications and telemetry
applications. The consequence of this is that the relevant approved frequency
ranges may be used by many transmitters at the same time, depending on the
time and location.
The transmission method used by Demag is designed for the most robust and
interference-resistant radio transmission between the transmitters and receivers
of the DRC range.
The state-of-the-art transmission method is provided with technical features (e.g.
frequency hopping) which are intended to ensure a minimum of conflicts for radio
operation together with other transmitter and receiver devices which use the same
frequency range.
Despite all of the technical precautions taken by Demag, it cannot be entirely excluded that the transmission characteristics of other radio systems are impaired,
in particular devices supplied by other manufacturers that use the same frequency
range, or that the transmission characteristics of the system supplied by Demag
are negatively affected. In such cases, interference or radio connection interruptions may occur, which disrupt the communication and function of a system supplied by Demag or other manufacturers. Such impairment or interference does not
constitute a defect on the part of DRC transmitters and receivers. Demag will only
accept liability for wilful or grossly negligent behaviour on its part.
The number of transmitters that operate without any interference in a given area
depends on the relevant radio solution design of all systems and the selectivity of
each individual system.
If this limit is exceeded continuously or for certain periods, additional technical
measures may be necessary in order to ensure simultaneous and interferencefree operation of the radio systems. Whether and to which extent such measures
are required can only be determined by means of suitable measurements on site
or when the system is put into operation. Demag is not responsible for such additional technical measures.
Radio remote control systems of the DRC range are exclusively intended for
single-transmitter operation; i.e. there is always a clear assignment between a
specific transmitter and the corresponding receiver.
The DRC-J joystick control system may only be operated when in perfect working
order by trained personnel in accordance with the relevant safety and accident
prevention regulations. This also includes compliance with operating and maintenance conditions specified in the operating instructions.
In Germany, the owner of a crane installation with radio control system is
responsible for compliance with accident prevention regulations BGV D6.
DRC-J joystick control units that are ready for operation must not be left
unattended They must be protected against unauthorized use.
For appropriate use, the information in the operating instructions for the receiver
used (DRC-DR/DRC-MP) and the machine/crane installation to be controlled
must be complied with in addition to the information contained in these operating
instructions.
Serious personal injury or damage to property may occur in the event of:
unauthorized removal of covers,
inappropriate use of the product/system,
incorrect operation,
insufficient maintenance,
working on live parts.

First check that the voltage and frequency specified on the type plates match
the owner s mains power supply.
In the course of putting the product into service, it may be necessary to render
safety devices or features inoperative when carrying out adjustments or function
checks.
When putting the machine into service, it may be necessary to perform work in
the danger zone, therefore, it must be ensured that only appropriately trained
personnel are employed for this work.
2.7 Safety instructions for
operation
Before putting the crane into operation, the operating personnel must be satisfied
that the radio control system is in safe and correct operating condition.
In addition, the safety instructions and measures contained in the operating instructions of the crane must be applied.
The clear assignment between the DRC-J joystick control system to the radio
receiver (DRC-DR/DRC-MP) on the crane is the precondition for safe wireless
remote control of a crane. This unique assignment is created by the exchange
of the address features between transmitter and receiver when a DRC-J joystick
control system is put into operation. The operating personnel recognises which
crane is controlled by means of the crane identification shown in the display of the
joystick control unit.
Before switching on/putting into operation of the crane/machine controlled by the
radio control system with the DRC-J joystick control system, it must be ensured
that nobody is endangered by operation of this crane.
If the operator notices persons who may be exposed to a risk to health or personal
safety by operation of the equipment, he must suspend operation immediately and
may not resume operation again until the persons are outside the danger zone.
STOP key function
Actuation of the red STOP key activates the emergency-stop function in the radio
receiver on the crane. The emergency-stop function stops any potentially dangerous movement of the crane. For use of the emergency-stop function, in particular the instructions contained in the operating instructions of the crane must be
complied with. When the STOP key has been actuated, the radio system is in the
!STOP" operating mode. No movement commands are transmitted. The STOP
key latches when actuated. To quit the EMERGENCY stop function, first turn the
STOP key to unlock it and then actuate the Start/Horn key. This may only be done
after the operator has made sure that the hazardous situation which resulted in
actuation of the STOP key has been eliminated.
Warning device function
Radio-controlled cranes must be provided with a warning device (acoustic or
optical). The crane operator can activate this warning device by means of the
horn key to warn persons in the vicinity of the crane and/or load before starting
the crane movements. The warning device must also be used if the crane operator
intends to check the assignment between the joystick control unit and the crane
receiver by means of a joystick control command.
Range of the radio remote control system
The crane operator may only use the range of the radio control system to the extent that he can freely monitor the danger zone of the crane movements.
The range of the hand-held radio transmitter is limited and can be additionally
reduced by ambient conditions. The range may also be limited by utilization of
the available frequency range by other radio transmitters. The quality of the radio
signal is shown in the display of the joystick control unit. If poor connection quality
is displayed, unintended interruptions of the controlled movements may occur.

3 General description
3.1 Transmitter/receiver
interface
Demag DRC radio control systems are designed for wireless control of hoist units
and cranes. They are the interface for manually controlled crane installations. The
applicable EC directives and standards are complied with for this application.
Demag DRC radio control systems consist of a radio transmitter/operating unit and
a radio receiver with interface to the crane control system.
DRC-J joystick control systems in applications in connection with DRC-DR or
DRC-MP radio receivers are the subject of these operating instructions.
Radio receiver
DRC-DR
The Demag DRC-DR radio receiver is a pluggable PCB for installation in the
electrical equipment cover of the DR hoist unit. The interface of this receiver
component to the crane control system and power supply by the DR electrical
equipment is the CAN safety bus. The DRC-DR radio receiver is exclusively
suitable for operation with a DR hoist unit.
The Demag DRC-MP radio receiver is a complete unit with its own enclosure
and power supply from the control voltage network of the crane installation.
Relay contacts for the individual control commands and the EMERGENCY stop
circuit form the interface of this unit to the crane control system. An additional
semiconductor output with pulse width modulation is provided for infinitely variable crane drives. The DRC-MP radio receiver is suitable for a wide range of
applications.
Demag radio receivers are provided for duplex operation and transmit information
to the DRC-J joystick control system. This increases safety of the radio system.
Status information of the crane control system and the receiver are shown in the
display of the DRC-J joystick control unit.

3.2 Transmission method
12
The so-called ISM band (433 MHz) is used for transmitting the radio signals
between transmitter and receiver. Witin the ISM band 30 frequencies are used
alternately in a defined sequence (so-called frequency hopping). A random-check
generator detemines the sequence of the frequencies when radio transmission is
started. In order to increase transmission reliability, the information is transmitted
several times. This method in connection with frequency hopping provides for a
very high immunity to interference.
Frequency hopping is used for the first time with Demag DRC radio control system
types D1-FH and D2. In the case of the D1 type, the frequency of the radio signal
is not changed during a transmission cycle.
A decisive advantage of the frequency hopping transmission is that existing information contents are transmitted on several physical channels. This redundant
radio transmission 1) provides for an exceptionally high insensitivity of radio
transmission against other transmitters or electromagnetic interference.
1) Certain information contents are transmitted on up to 5 different frequencies. Only if (theoretically)
all frequencies used were occupied or disturbed by other radio systems, communication would be
interrupted.
