2 Safety instructions
2.1 Symbol description
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-MP radio receiver is intended to be used as a receiver unit for DRC-10
and DRC-J radio transmitters. The scope of functions is preferably designed for
the wireless control of crane installations, travelling hoist units, chain and rope
hoists, transfer carriages and similar applications.
Thus for these applications, the conventional permanently wired control equipment
(control pendant) can be dispensed with. The operator can position himself as
required. He can freely move loads and control equipment from a safe distance in
line with the local conditions.
The unit to be controlled must be provided with a contactor control system.
The outputs of the DRC-MP radio receiver are relay contacts that are connected
to the contactor control system of the system to be controlled. The DRC-MP radio
receiver is supplied by the control voltage source of the contactor control system.
The voltage and frequency of the contactor control system must match the data
specified on the rating plate of the DRC-MP radio receiver. The specified power
consumption of the receiver must also be taken into account.
DRC-MP radio receivers are exclusively intended for single-transmitter operation;
i.e. there is always a clear assignment to a specific transmitter (DRC-10 or
DRC-J).
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.
6
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.
Radio remote control systems of the DRC range 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.
For appropriate use, the information in the operating instructions for the radio
transmitter used (DRC-10/DRC-J) and the machine/crane installation to be
controlled must be complied with in addition to the information contained in these
operating instructions (see accompanying documents, page 2).
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.

3.2 Transmission method
The DRC-MP radio receiver can either be used with a DRC-10 hand-held transmitter or with a DRC-J joystick control system.
Radio receiver
DRC-MP
Hand-held transmitter
DRC-10
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 its corresponding radio receiver.
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.
Joystick control
system DRC J

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.

In conjunction with the specified radio transmitters, the DRC-MP radio receiver
complies with the relevant European directives and fulfils the requirements of the
standards for cranes and hoists: EN 13557; EN 60204-32. The stop function fulfils
safety category 3 to EN 954-1.
All components are designed for operation in industrial environments.
The requirements of the EC EMC directive are complied with in terms of the limit
values for industrial environments.
In the Federal Republic of Germany, the BGV D6 and ZH1/547 regulations must
be complied with for operation of a crane with radio-remote control.
To comply with the EMC requirements, the following points must be considered for
integration into overall systems:
Integration of electronic components to meet EMC requirements
Use of prescribed or approved cables, screened cables, if required.
Adherence to minimum distances for the application of cables and wiring with
different potentials.

5 Putting the DRC-MP radio receiver into operation for the first
time
5.1 Assembly and
connection of the
radio receiver
Fitting the radio receiver:
Bolt radio receiver housing to location where the receiver is to be mounted (switch-
gear cabinet, wall, etc.).
Connect the receiver to the installation to be controlled by means of the connected
multi-pole connection cable.
Power supply to the radio receiver is via a connection cable (control voltage).
42365144.eps
42365244.eps
Observe operating voltage of the radio receiver.
Mount the radio receiver only in an upright position (cable out downwards).
Do not fit radio receiver inside switchgear cabinets or in recesses.
All contacts/potentials are provided acc. to connection diagram section 5.4 via one
multi-pole cable that must be connected.
The DRC-MP radio receiver must be connected to the control system in accordance with the circuit diagram of the supplier of the installation/machine or equipment.
The block wiring diagram in chapter 6 shows the example of an overhead travelling
crane control system with connected DRC-MP radio receiver.
The DRC-MP radio receiver is supplied without connection cable as standard.
For connecting the DRC-MP radio receiver, a cable of type HYSLY-JZ with a con-
ductor cross section of 0,75 mm² must be used. The connection cable must be
rated in accordance with the circuit diagram.
If required, a pre-fabricated 42-pole connection cable may be ordered from
Demag. Part no. 773 429 44
This connection cable is already provided with the appropriate connectors that
make easy connection to the DRC-MP radio receiver possible.
Ensure that the installation/machine is at zero voltage according to the regulations
and is secured against accidental restoration of the power supply for connection of
the DRC-MP radio receiver.
When the control voltage has been switched on, the radio control system can be
put into operation in accordance with the operating instructions of the transmitter
used (DRC-10 or DRC-J).
For the first function test, we recommend that the main current supply to the drive
motors be switched off.
When delivered, the DRC-MP radio receiver has crane identification "NOID#. All
crane movements are blocked. This block is removed when the unit is put into operation by assignment of a valid crane identification to the receiver in accordance
with the operating instructions of the relevant transmitter (DRC-10 or DRC-J).
13
When fitting the receiver, make sure that the aerial is free to the extent possible
(see figure in section 5.1).
Any shadows, in particular those caused by metallic parts in the direct
vicinity of the aerial, have a negative effect on the max. possible range as
well as on the stability of the radio connection between transmitter and
receiver.
A "free view to all sides# from the point of view of the receiver aerial on the working
range of the assigned transmitter is optimal.
If the mounting location of the receiver does not permit optimal placement of the
aerial, we recommend that an aerial offset from the receiver be used.

5.5 Activating and
adjusting special
functions
DRC-MP radio receivers are provided with adjustable special functions to adapt
the sequence of switching processes for the control of the drive motors to the application and to feedback information on operating conditions of the installation to
the transmitter. The following functions can be set:
!BE function brake application control for travel motors, see section 5.5.1.
!Feedback channel information display of feedback channels, see section 5.5.2.
!SDGM function start-up control for pole-changing hoist motors, see sec-
tion 5.5.3.
!LIFT-FAST relay selection of the contactor control variant for pole-changing
hoist motors, see section 5.5.4.
When delivered, the DRC-MP radio receiver has the following settings:
Brake application control is switched off.
Display of feedback channel information un-encoded, i.e. I or I + II or II and
Start-up control for pole-changing hoist motors is switched off.
Selection of the contactor control variant with joint quick contactor (3-contactor
variant)

5.5.1 BE function general
When pole-changing squirrel cage rotor travel motors are switched down from fast
to slow speed, unwanted loads on mechanical components and load sway result.
It is therefore recommended to use the integral BE (brake application) function in
conjunction with the DRC-MP radio remote control system. This ensures that mechanical braking is started when the fast travel speed has been switched off. Only
after expiration of an adjustable delay time can the slow travel speed be switched
on again.

Description of BE function
If required, this function is activated for the travel axes by setting the DIP switches
on the board of the radio receiver (Default: switches 1 - 5 OFF).
After fast speed (V2) signal has been switched off, the fast and the slow speed
(V1) contacts open and thus generate mechanical braking. Upon expiration of
the time interval set and if the control signal (slow) is available, the slow speed is
switched on again for the drive unit.
If V2 is switched on again during the braking time, the contacts for V1 and V2
close without delay, i.e. the fast speed is switched on again.
Time intervals which can be set: 1 - 2 - 2,5 - 3 seconds and de-activation (by
means of a switch in the receiver).
Select time interval so that upon expiration of this braking time the travel drive has
been braked from V2 to V1.

5.5.2 Feedback channel information
DRC-10 hand-held transmitters and DRC-J joystick control systems are provided
with an integrated display, which can also be used for the display of feedback
channel information.
To implement this function, the DRC-10/DRC-J transmitter and the DRC-MP radio
receiver operate as bi-directional radio systems.
This means, that the DRC-MP radio receiver can also send data/information to a
DRC-10/DRC-J transmitter.
For this purpose, the DRC-MP is provided with three feedback channels on the
radio receiver side that are activated by means of an NO contact.
See connection diagram, section 5.4.
Two different display modes can be activated via DIP switch 6 (!encoded $ un-
encoded display ).
Setting for encoded
(DIP switch 6 on ON)
Setting for un-encoded
(DIP switch 6 on OFF,
default setting)
In this display mode, the three feedback channels are evaluated as a binary code
and displayed as number information on the display of the transmitter.

0005 1 0 1
0006 1 1 0

In this display mode, the status is displayed with the feedback contacts for control

IN3 closed Display of the !"warning# symbol
The meaning of the warning symbol must be defined in line with the application.
5.5.3 SGDM function
The SGDM function has been developed for high-performance, pole-changing
hoist motors to avoid overloads caused by frequent start-up and braking cycles.
1. Starting
This function ensures that the motor is always started by means of the winding
with the higher number of poles. As a consequence, switchgear and wiring can be
of a less expensive design. It is important that, when switching over to the winding with the lower number of poles, this is switched on before the winding with the
higher number of poles is switched off.
2. Braking
An important factor for the service life of brake linings is the speed at which braking begins. The speed ratio is used as a quadratic value for the calculation of the
service life of the brakes. For pole-changing hoist motors with a speed ratio of
1 : 6 this means that, when braking at the lower speed, the service life of the brake
linings is 36 times longer than that obtained when braking at the higher speed. The
SGDM function ensures that the hoist motor is always braked electrically when it
is switched from the main hoist speed to the creep hoist speed. This can be taken
into account when calculating the brakes, above all for larger hoist unit motors.
3. Functional sequence
3.1 Starting
When the appropriate button on the control pendant is pressed to the first step,
the direction of movement (creep lifting or creep lowering) is switched on immediately. If the button is pressed directly to the second step, the creep lifting speed
is switched on first and then, after approx. 0,4 seconds, the main lifting speed.
To prevent flick-switching during operation at main lifting speed, the SGDM stops
the hoist being switched on again for 2,5 seconds after the main lifting speed is
switched off. The delay times are preset at fixed values.
Changing the settings for the
SGDM function
3.2 Braking
When switching back from the second step directly to 0, the creep lifting speed is
automatically switched on for approx. 0,5 seconds. This delay time, too, is preset
as a fixed value.
If required, this function is activated for the lifting axis by setting the DIP switches
(Default:OFF).

5.5.4 LIFT-FAST relay
In the default setting, the contact of #LIFT-FAST# performs the #FAST# function (for
LIFTING and LOWERING).
The contact of #LIFT-FAST# always remains switched off.

When the lifting/lowering or lowering/lifting direction is changed, the corresponding
changes on the output relays on the receiver side are made with a fixed delay time
of 250 ms.
This delay is also effective when the SGDM functions is not activated.
For controlling pole-changing hoist motors with contactor control, two basic vari-
ants are used:
One variant with 3 coils and a joint contactor for the fast speed for lifting and lower-
ing (left figure) and a variant with 4 contactors so that for lifting and lowering, two
separate contactors for LIFT-FAST and LOWER-FAST are controlled (right figure).

5.6 Function check after
installation
A general function check of the receiver is possible by means of the light diodes in
the window of the cover, see also section 5.3.
The yellow LED flashes, when the receiver is supplied with current and no
hand-held transmitter has been assigned yet. In addition, the red LED flashes,
when radio telegrams of transmitters that have not been assigned are received.
The green LED flashes, when the receiver is supplied with current and radio
telegrams of an assigned hand-held transmitter are received. When this handheld transmitter is in Stop mode, the flashing sequence is approx. 5/sec. When
the hand-held transmitter is in Run mode, the flashing sequence changes to
rapid 10/sec.
Further function checks are only possible by operation of a suitable radio transmitter (DRC 10 or DRC J). Proceed in accordance with the operating instructions of
the radio transmitter and the crane installation.
A qualified electrician can check the status of the output contacts by means of
suitable measuring equipment based on the connection diagram, section 5.4. In
the receiver housing, activation of the output relays is indicated by the associated
LED. These checks may only be carried out by a qualified electrician, if measures
to protect against contact with live parts have been taken.
