2 Safety instructions
2.1 Symbol description 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-10 hand-held transmitter 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 move-
ments 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-10 hand-held transmitter 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.
2.2 Appropriate use

8
21492044.indd/131107
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 ex-
cluded 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 interrup-
tions may occur, which disrupt the communication and function of a system sup-
plied 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 interference-
free 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 addi-
tional 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-10 hand-held transmitter 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 mainte-
nance 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.
Hand-held radio transmitters that are ready for operation must not be left unat-
tended. 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 in-
structions (see accompanying documents, page 3).
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.

regulations must be observed when operating our products. Important information
and instructions are marked by corresponding symbols. Follow these operating
and safety instructions to avoid personal injury and damage to machinery.
The operating instructions must be kept available at the place where the system is
in use at all times.
They include significant aspects and appropriate excerpts from the relevant guide-
lines, standards and regulations. The owner must instruct his personnel appropri-
ately. If the safety instructions given are not observed in any way, personal injury
or even death can result.
Observe general statutory and other obligatory regulations relating to accident
prevention and environmental protection and basic health and safety requirements
in addition to those included in these operating instructions.
Such requirements may also relate, for example, to the handling of hazardous
materials or the provision/wearing of personal protection equipment.
Comply with these regulations and general accident regulations relevant for the
place at which the system is used and follow the instructions therein when working
with the system.
The system may still constitute a danger to life and limb if it is not installed, oper-
ated, maintained or used appropriately by personnel which have not been trained
or specially instructed.
The safety instructions must, if required, be supplemented by the owner with in-
structions and information (e.g. factory regulations) relating to organization of work,
working procedures, operating personnel, etc. Supervising and reporting obliga-
tions as well as special operating conditions must also be taken into consideration.

disassembly
The system must be taken out of service immediately if functional defects or
irregularities are detected.
In the event of a stoppage (e.g. if defects regarding safe and reliable operation
are detected, in emergency situations, in the event of operating malfunctions, for
maintenance purposes, if damage is detected or after finishing work), the operator/
experienced technician must carry out all prescribed safety measures or observe
that they are automatically carried out.
Personal protective clothing must be worn as necessary or as required by regula-
tions. Personnel must not wear loose clothing, jewellery including rings or long
hair loose. Injury may occur, for example, by being caught or drawn into the
mechanism.
All safety and hazard warnings on the product, its access routes and mains
connection switches must be preserved completely and in legible condition.
Modifications, additions to and conversions of the product which might impair
safety in any way must not be carried out without the approval of Demag.
Safety devices must not be rendered inoperative.
Only genuine Demag spare parts may be used. Observe prescribed deadlines
or those specified in the operating instructions for routine checks/inspections.
•Installation and disassembly work may only be performed by experienced
technicians.
•Installation and disassembly work must be co-ordinated by the person carrying
out the work and the owner within the scope of their responsibility.
•The assembly zone must be made safe.
•The installation must be isolated in accordance with the relevant electrical
regulations.
•Customer-specific regulations must be observed.
•Only appropriate, tested and calibrated tools may be used.
In the case of disassembly, any waste material must be disposed of by the owner
in an environmentally compatible way in compliance with the valid regulations.

11
21492044.indd/131107
2.6 Safety instructions
when first putting the
unit into service after
completing installation
•The working area must be made safe.
•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 unit into service, it may be necessary to perform work in the
danger zone, therefore, it must be ensured that only appropriately trained per-
sonnel are employed for this work.
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 in-
structions of the crane must be applied.
The clear assignment between the DRC-10 hand-held transmitter 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-10 hand-held
transmitter is put into operation. The operating personnel recognises which crane
is controlled by means of the crane identification shown in the display of the hand-
held transmitter.
Before switching on/putting into operation of the crane/machine controlled by the
radio control system with the DRC-10 hand-held transmitter, 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 danger-
ous movement of the crane. For use of the emergency-stop function, in particu-
lar 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 emer-
gency-stop can be unlocked again by entering an electronic 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 opti-
cal). The crane operator can activate this warning device by means of the signal
key in the keyboard of the hand-held transmitter 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 hand-held transmitter and the crane receiver by means of a hand-held trans-
mitter 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 hand-held transmitter. If poor connection
quality is displayed, unintended interruptions of the controlled movements may
occur.

Radio receiver
DRC-DR

DRC-MP
Hand-held transmitter
DRC-10
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-10 hand-held transmitters in applications in connection with DRC-DR or
DRC-MP radio receivers are the subject of these operating instructions.
•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 vari-
able 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-10 hand-held transmitter. 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-10 hand-held transmitter.
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 in-
formation contents are transmitted on several physical channels. This redundant
radio transmission 1) provides for an exceptionally high insensitivity of radio trans-
mission 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.

As standard, all keys on the hand-held transmitter are designated in the factory
with the relevant foil symbols.
If requested by the owner, it is also possible to apply other, for example, country-
specific symbols for the direction keys on the radio control system. The owner then
has to remove the existing symbols and apply symbols required by him. Note that
when the radio control system is used in connection with a DR rope hoist, the func-
tions of the individual keys are pre-defined.
To replace the symbols, proceed as follows:
•The keys must be free from adhesive, dust and grease. Clean, as required, with
spirit or alcohol.
Solvents, benzene, cold sprays, etc. could damage the key mate-
rial. (see fig. 1 for hoist unit functions)
•Remove the symbol required for the assigned function from the symbol sheet.
Attach the adhesive symbols in the relevant function key.

The hand-held transmitter is provided with a display. In the display, all data impor-
tant for operation of the crane to be operated are shown.
The number of information items displayed varies depending on the type of re-
ceiver. The scope of display functions comprises the general displays which are
available for both receiver types and additional information that can only be used
with DRC-DR receivers.
In the case of temperatures below 0 °C, the contrast of the LDC display is reduced
and the time for changing the characters increases.

Every crane with wireless control must be identified by means of an easily visible
crane identification/number. Travel direction symbols on the crane and the travel-
ling hoist must identify the movement directions of the travel motions in line with
the identification of the keys on the hand-held control system.
The coding labels are used for illustration of the crane identification on the
travelling hoist or on the crane. The crane identification illustrated by means of the
coding labels must be identical with the crane identification shown in the display of
the DRC-10 hand-held transmitter.
