1. GENERAL DESCRIPTION OF THE REMOTE CONTROL SYSTEM.
The Scanreco RC 400 remote control system has been specially developed for hydraulically
driven mobile cranes and machinery. The System is a digital remote control system based on
an extremely advanced micro-processor technologyr Years of exhaustive and demanding
testing have shown that the remote control system can cope with the roughest of environ»
ments.
The remote control system is tested and approved for use in, amongst others, power stations,
with a sky lift for personnel, close to work areas using blasting , on oil platforms, military
establishments or other areas with explosive environments The system is protected against
electromagnetic and radio frequency radiation and can be installed onto all hydraulic valve
types ( voltage, current, pulse width, or protocol steered ) found on the market.
In its basic form the remote control system is comprised of a portable control unit with
manoeuvre levers for proportional control and switches for ON/OFF functions, an electronic-
box with connection cable for driving proportional electro-hydraulic slide controllers.
Digitally coded control information (lever deflection and switch position) is sent from the
control unit via electric cable, opto fibre cable or via radio to the electronicbox,
The control unit and electronicbox translate the magnitude and direction of the manouevre
lever deflections and switch positions to corresponding valve function speed and direction and
thus crane movement.
2. PORTABLE CONTROL UNIT 1 for cable, opto fibre cable, and radio operation 1.
General description of the portable control unit.
The portable control unit is impact and weather resistant and is light weight and compact.
Controls are available for 3, 4, 5 or 6 manoeuvre functions The manoeuvre levers are fully
proportional and have spring return to the zero position. i.e. a "dead—man‘s-handle”. The
control unit has an emergency stop function which will immediately stop all movement .
All manoeuvre levers are protected with a protective frame against unintentional activation
and against mechanical damage. The control unit has multi-step micro-speed operation as
standard enabling instantaneous temporary reduction of speed and it can also be equipped
with a large number of switches for ON/OFF functions. A LED and sound signal are used to
indicate such things as operating and battery status and for a simple and diagnostic fault
finding. ( See picture of control unit).

Portable control unit with battery operation ( radio control oropto fibre cable ).
A battery is located in the control unit for radio control and is very simple to change
- The battery’s effective operation time is about 8 hours on one charge.
- When the battery is approaching time for charging, the control unitbeegs three ( 3 ) times
as a warning and at the same time the LED starts to blink on the control unit,
0 The battery m be used until the LED goes out, after which it can be changed.
If the battery capacity is too LOW the control unit cannot be activated.
. The battery capacity and operational performance is reduced in extremely cold conditions.
( The battery is automatically charged during operation by cable control ).
c In order to reduce battery loading and for safety reasons, the control unit is turned off
automatically, after the unit has been idle for more than approximatelyfifl ( 5 ) minutes.
General system description 2 - 5
A brief description is given now of the component parts of the control unit.
The control unit is comprised of manouevre levers for proportional control, switches for
ON/OFF and function changing, micro—operation and emergency stop. ( See separate headings
below ).

Manoeuvre levers.
The manoeuvre levers give fully variable proportional operation and are sprung loaded to
return to zero position, i.ei "deadvman’s—handle". When the manoeuvre levers are moved from
zero position the respective hydraulic function starts to operate slowly and increases in speed
as the lever is moved further from zero position and vice versa as the lever is moved back
towards zero position. If any levers are not included for a particular installation, a cover plate
can be mounted for the unused lever locations.
( See also trtle ” Micro-speed Control " ).
For safety reason: all manoeuvre lever: M be in they zero/neutral positionr for a start-up 10 be made If any
lever is not in its sew /neu{ralpusilion during start-up the control unit will blmk and beep the same number of
times as the number ufrhe lever ta indicate which manoeuvre lever isfuulty. The cumml unit can be used but the

Switch panel ( Micro-speed, ON/OFF and function change functions ).
The control unit can be equipped with different switch panels, depending upon the particular
installation.
There is a switch for micro-speed operation, i.e. speed control, as standard on all switch
panels, Switch panels are equipped with different types and combinations of switches for
ON/OFF manoeuvring or for function changing.
Alternative One switch can be used to designate tha/ levers n ill give ON/OF F functions (functinn changing).
Micro — Speed control ( reduction of speed ).
This return sprung switch can be used to reduce the operating speed in fig ( 5 ) steps from
100% to 6070, 50%, 40%, 30% and 20% speed by limiting the hydraulic steering. The
regulation of the function‘s speed is still made over the entire lever stroke and with retained
resolution.
- With impulses from the sprung loaded toggle switch to the left, towards ON, speed
reduction can be produced from 100% to 60%, 50%. 40%, 30% and 20% steering,
- Movement of the switch to the right, towards OFF. will produce 100% steering once
again ( See also next item ).
. For safety reasons, a return to 100% steering can only be made if all manoeuvre levers are
in their zero positions.
- NOTE !! If the emergency stop is pressed on the control unit, the control unit will restart
from the normal position, i.e. lOO% steering.
(As visible acknowledgement that micro operation is relected. the control unit': red LED will light/or along
period and then extinguish fur a shortperma', this sequence then betng repeated. Do not mistake lhl: for
”low battery capacity” )

ON/OFF and function changing functions.
ON/OFF switches can be used to manoeuvre electrical, hydraulic or pneumatic ON/OFF
functions.
Examples of functions :
. Stopping and starting of the vehicle’s motor, throttle lever, beep / signal, change—over
valves, function changing for ex, 7th and 8th function.
- Enable parallel running of two or more valves at the same time from one manoeuvre lever.
- Connection of so called hold function, i.e. "lock" 21 function at a specific speed, after
which the speed is kept constant without the lever having to be held ( for example
hydraulically driven drills ) etc. This can be compared to the speed control in a private car.
Make sure that you always know which functions are connected for ON/OFF manoeuvring.
Alternative One swrlch can be used to designate that levers will give eitherpropwiiunnl or ON/OFFfuncrians

Installation instructions for Scanreco RC 400 remote
control system .
When the Scanreco RC 400 is installed an electrically controlled dum valve must, for
reasons of safety, always be connected between the manoeuvre valve and the tank . This
means that during an emergency stop manoeuvre the dump valve will be without power
and will transfer the pump flow directly to the tank thus making the crane entirely
without hydraulic pressure.

Welding.
It is sometimes necessary to weld a truck/machine. During welding the system’s electrical
connections must a ways be disconnected from other equipment, ie. power supply cables ( +
and - ), all valve contacts, the EX cable and radio receiver box contact must be disconnected,
1. Before installation is started, it is recommended that a test run is made of the existing crane
system (movement and functions) in order to discover existing faults or operational
disturbances in the crane, hydraulic valves or other functions. Note these and notify
the customer if any faults are found.
Installation instructions 4 — 3
Installation and mounting instructions.
Electronicbox :
Important: The electronicbox M be mounted in accordance with the recommendations
given below! To ensure the longest possible life for the electronicbox and its cables, the
electronicbox must always be mounted so that the valve contacts are located facing
downwards. The electronicbox must not be mounted so that the cables face upwards The
reason for this is to hinder water from running via the cables towards the electronicbox.
( The cables on the electronicbox are thus Lot subjected to long periods of accumulated water, damp, salt etc. ).
The electroniebox should be mounted in a vibration free location and not close to strong heat
sources ( for example exhaust pipes etcr ). See also page 4.5 - 4.6 !
OK OK WRONG
Radio receiver box :
Important: The radio receiver box M be mounted in accordance with the recommendations
below!
The radio receiver box must be mounted in a vibration free location and not close to strong
sources of heat ( for example exhaust pipes etc. ). See next page !
OK WRONG WRONG
Installation instructions 4 - 4
Mounting of the radio receiver box.
. The connection cable (marked RA ) for the radio receiver box is approximately 2 metres
long which is the maximum mounting distance from the electronicbox.
- For optimum radio communications the radio receiver box should be located as high and
frfi as possible, An antenna screened and surrounded by fixed objects will considerably
impair radio reception
- The antenna pin must not touch any metal object. The radio receiver box should be
mounted horizontally with the antenna pin sticking vertically up. ( See instructions f).
- The radio receiver box should be mounted in a vibration free location and not be
subjected to strong sources of heat ( for example exhaust pipes etc. ).
Control units and electronicboxes with the same serial number have been programmed with a unique "identity
code" when delivered, i.e. they do not need to have their identity codes programmed. See section "Identity code
programming" ifthis is not the case.
NOTE! Marine cranes : The casing of the radio receiver box is grounded and connected to supply voltage
earth. In those special cases where a galvanically isolated earth is required ( for ex. marine use ). the radio
receiver's boxmust be mounted on rubber siand—offslhushes to obtain a galvanically isolated earth,

2. Select a suitable location for the electronicbox on the vehicle / crane.
a The contact for the cable control cable, switches for MANUAL/ 0 / REMOTE and LEDs
for operational status must be located where they are easy to see and reach. Check that
the electronicbox cable contacts ( cable control, ON/OFF, and radio receiver box
connection contacts ) are located so as to be protected from external damage.
0 If the electronicbox is to be mounted in any other manner, the connections and contacts
must n_ot face upwards ! This is to hinder long-term accumulations of water, damp and
corrosive salt in the cables, connections and contacts.
NOTE! Marine cranes : The casing of the electromcbox is grounded and connected to supply voltage earth. In
those special cases Where a galvanically isolated eanh is required ( for ex. marine use ), the radio receiver’s box
must be mounted on rubber stand-offs/bushes to obtain a galvanically isolated earth.
3. Connect the electronicbox valve contacts, as per the schematic in which each valve group
and function can be seen. A valve gasket is mounted under each valve contact and to
prevent future operational disturbances, a weatherproof grease / silicon should be applied
between the valve contact and the manoeuvre valve.
- The valve contacts for the electro—hydraulic slide controller are marked and numbered
1 2 3 up to 8.
(The control unit's Icfl manoeuvre [ever I = valve contact I).
(The control unit”: n‘ghf manoeuvre lever 6 : valve Contact 6 )»
~ The valve contacts for the dump valve are marked M. ( Max. output drive max JAM.)
( Thefimction is automatically cut of/ifluaded by more than 2Amp.. t' e the output tr not damaged ).
- All cable and valve contacts must remain in place even for valve contacts which are not
used. Unused valve contacts should be carefully sea ed with grease and electrical tape
( to keep damp out which could cause operational disturbances / alarms ).

4. Next install any ON/OFF functions required. The ON/OFF cable is marked EX and should
be connected to the "ON—OFF" contact on the electronicbox.
- Non'nal ON/OFF function usage is to drive a signal lbeep function, throttle lever,
changeover valves, motor start/stop etc. See connection recommendations for the
starting of a motor !
Each ON/OFF function can drive a maximum of 1.2 Amperer
. The output function is disconnected automatically if loaded by more than 1.2 Amp., i.e.
the drive output is not damaged.
( For higher output drive an auxiliary relay can be mounted. See connection schematic

Connection of motor start / start lock :
- To protect the starter motor against unintentional re-start attempts after the vehicle motor
has already started, it is recommended that an electric "start lock" is connected in after the
motor start signal from the electronicbox, EX cable pin 2 ( See connection example
below )i
a To be able to find out if the vehicle motor is already started, a signal can be taken, for
example, from the generator. In this way the crane drivercannot activate the starter motor
by mistake.
- Before connection, consult the truck manufacturer, customer and inspector !

Changing the direction of crane movement.
The description which follows describes how to change the direction of movement if the
crane moves in a different direction to that desired.
Example:
After installation and test operation it is found for example that the 3rd and 5th lever move?
ments operate in the opposite direction to that desired. See the example below for how to
change the 3rd and 5th lever movements.
DO AS FOLLOWS!
1.
Remove the battery pack. Connect the cable between the control unit and electronicbox
and test run the crane. Then press the emergency stop on the control unit and emergency
stop on the crane.
. Twist up the emergency stop on the control unit and on the crane.
. Press the control unit's ON/SIGNAL/FREQ.-Sl—IIF1' button.
(The red LED should light continuously).
Press spring return switch MICRO in veg quick succession to the RIGHT in the OFF
direction to produce impulses until the control unit gives a long beep signal. Wait approx.
12 seconds for a new long beep signal then continue with item 5.
Note 1. The red LED will be extinguished each time the control unit gives a beep signal.
Note. 2. If you do not receive the first long beep signal, start again from item 1 and execute items 3. and 4.
quicker. Items 3. and 4. must be executed within max. 5 seconds.
. Now press ON/SIGNAL/FREQ.-Sl-IIFT once.
( The control unit’s built-m beeper wtll give a short beep once every 5 seconds It) confirm that the item:
above have been done correctly [forty other beep signals are heard you must restartfi'om item I again 1.
Now you can easily change the crane direction, see item 6.
Now you can operate the crane. Move the 3rd manoeuvre lever ( which is operating in the
opposite direction to that desired ) away from zero position until the crane just starts to
move and hold it there then give switch MICRO an impulse to the LEFT in the ON
direction. The crane will now change direction and continue with the same selected speed,
in the opposite direction. Do the same with the 5th manoeuvre lever.
Move the 5th manoeuvre lever (which is operating in the opposite direction to that which is
desired) away from zero position until the crane just starts to move and hold it there and
give toggle switch MICRO an impulse to the LEFT in the ON direction.
The crane will now immediately change direction and continue with the same selected
speed in the opposite direction. ( If a direction change has been made earlier/or a particular lever. do
(he same as above but give toggle switch MICRO an impulse to the RIGHT, in the OFF direction).
Operate and check that all crane movement is now in the desired direction.

Functional description.
To simplify service and faultfinding, the portable control unit can be put into internal TEST-
MODE.
This means that the service man can easily control the control unit's switches and manoeuvre
levers, without the need to open the control unit.
When each switch or manoeuvre lever is activated / manoeuvred the control unit gives a
"beep - signal" to confirm that the function is working.
When "TEST - MODE" is selected M transfer of proportional, ON/OFF, or dump valve
functions is made to the electronicbox.

8. PROGRAMMING PARAMETERS AND
SETTINGS.
E H"
The Scanreco RC 400 offers considerable possibilities for system constructors of hydraulically
driven mobile cranes and machines. The program in the control system is very comprehensive,
flexible and has many adaptation possibilities for specific applications. The control system
offers simple programming of a number of functions which can easily be turned on or off or
altered during operation.
To obtain the best manoeuvre characteristics in the simplest way, all programming /calibr~
ation of manoeuvre characteristics is made during operation ( so called on—line ). All prog-
ramming / calibration is made from the portable control unit. Programming is simple and
does not require tools / instruments or any special knowledge.
(Programming can ofcuurse be also madefrom a PC, terminal).
The control system is furnished with and prepared for 2-way (duplex) communications and for
signal handling of functions such as ramp. parallel, lock, ”dead-man’s", hold, double and
overload / lift reduction etc.
THE SYSTEM HAS 4 LEVELS OF AUTHORISATION:
- Authorisation level 1. (Installer),
- Authorisation level 2. ( Well trained installer, well trained service personnel ).
- Authorisation level 3. ( Well trained crane and valve manufacturer, well trained system
constructor ).
- Authorisation level 4. ( Scanreco AB, Sweden ).
- Authorisation level 1: | Installer 1.
LA To change the direction ofthe crane.
If the crane moves in the opposite direction to that which is desired.
- Authorisation level 2: 1 Well trained installer, well trained service personnel 1.
- 2.A Individual changes to the manoeuvre valve star1 speed for A or B ports.
If the manoeuvre valve’s starting value "dead-band” is to be increased or decreased for A or B port.
- LB Individual speed reduction for A or B ports.
Individual maximum manoeuvre speed reduction for a particular critical function ( e.g.
swing function ). Fully variable speed reduction can be made for manoeuvre valves on the A
or B portst This enables the crane driver to pre-set the maximum oil flow for each individual
function ( A or B port ) as required.
- 2.C Individual changes to micro - speed control for A or B ports.
Due to non-symmetry in certain valves hydraulic system or in the crane / machine the micro
speed can be less well defined. If this is the case the micro-speed final speed can be changed
and adjusted (i.e. for max, lever position) for A or B port for all movements,
Nate: After [he completed odjuslmem afthe micro-speed ,
The remaining micro-Speed’s "reduclion steps ” will be proportional to the railing.
Programming parameters and settings 8 — 2
- 2.D Individual delayed start and stop movements ( ramp functions acceleration and
retardation ).
Ramp functions give soft start and stop movements which protects the crane / machine against
overloading during careless manoeuvring.
Start delay, i.e. this is the time required for the manoeuvre valve slide to reach its final
posttion from the time the manoeuvre lever has left its neutral position. The time can be
set individually to between 0 and 5 seconds for A and B ports. ( See tables below ! )
Stop delay, i.e. this is the time required for the manoeuvre valve slide to come to its neutral
position after the manoeuvre lever has been placed in the neutral position The time can be
set individually to between 0 and 5 seconds for A and B ports. ( See tables below ! )
- Authorisation level 3.
( Only a few of the functions are described here) :
- Individually programmable manoeuvre curves.
The basic characteristics of the manoeuvre curves can be varied extensively. The manoeuvre
curve in relation to the manoeuvre lever can be linear, linear with different curve slopes or
with a break point in the manoeuvre curve The appearance and characteristic of the
manoeuvre curve can be individually installed for each valve section ( A or B port ) for
example for a particular critical function.
- Programming for the 7th and 8th valve movements or for serial tandem operation.
- Double function ( different control characteristics depending upon speed, ramps etc. ).
- Hold function: ( i.e. "lock" a function at a particular speed, after which the speed will be
kept constant without the lever needing to be held ).
- Dead-man's function (can be designed to cater for different safety requirements )4
- Individual or common reduction functions. A reduction or stop can be ordered by external
input signals in critical situations if the crane / machine becomes overloaded or / and
overturns External input signals can also cause reduction of speed of all functions to be
made in the case of insufficient pump capacity. With external input signals, when the crane
driver is working from a sky lift. an automatic reduction/decrease of speed can be made.
With external input signals the control system can always drive the support legs down but
upwards only if the pressure in cylinder is so low that the vehicle is standing firmly, etcr
- Automatic dumping: ( an optional time can be set for automatic dumping/unloading, which
means unnecessary heat generation is avoided and a further increase in safety ).
E.t.c.
The Installer/system designer is responsible for seeing that the RC 400 is used correctly
for all applications and is responsible for any re-programming of the system functions
and the characteristics changes caused by this.
See section 2.D. Ramp timesfor various classes are given in the tables below ( Classes t] to 15) :

Changing the direction of m ment of the crane.
This describes how changes in direction ol‘ movement are made if the crane moves in the
opposite direction to that desired.
Example:
After installation and test operation it is found that the 3rd and 5th lever movements operate in
the opposite direction to that desired. See the example below for how to change the 3rd and
5th lever movements.
D0 AS FOLLOWS!
1, Remove the battery pack. Connect the cable between the control unit and electronicbox and
test run the crane. Then press the emergency stop on the control unit and emergency stop
on the crane.
2. Twist up the emergency stop on the control unit and on the crane.
3. Press the control unit’s ON/SIGNAL/FREQ.~SHIF1‘ button.
(The red LED should light continuously).
4. Produce impulses in very quick succession with spring return switch MICRO to RIGHT in
the OFF direction until the control unit gives a long beep signal. Wait approx. 12 seconds
until the next long beep signal then continue with item 5.
Note 1. The red LED will be extinguished each time the control unit gives a beep signal.
Not 2. If you do not receive the first long beep signal, start again from item 1 and execute items 3. and 4.
quicker. Items 3. and 4. must be executed within max. 5 seconds.
5. Now press ON/SIGNAL/FREQ-SHIFT once.
( The control unit's built-in beeper will give a short beep once every 5 seconds to confirm that the item:
above have been dune correctly. Ifuny other beep signals are heard you must restart from [Ian I again ).
Now you can easily change direction, see item 6,
6. Now you can operate the crane. Move the 3rd control lever ( which is operating in the
opposite direction to that desired ) and give switch MICRO an impulse to the LEFT in the
ON direction.
The crane will now change direction and continue With the same selected speed, in the
opposite direction. Do the same with the 5th manoeuvre lever.
Move the 5th manoeuvre lever (which is operating in the opposite direction to that which is
desired) and give toggle switch MICRO an impulse to the LEFT in the ON direction
The crane will now immediately change direction and continue with the same selected
speed in the opposite direction. ( If a direction change has been made earlier for a particular lever, do
the rame as above but give toggle switch MICRO an impulse to the RIGHT, in the OFF direction)
Operate and check that all crane directions go in the desired direction.
7. Press the emergency stop on the CONTROL UNIT.
Programming is now completed and the crane is operating in the directions YOU decided
in item 6.
( Fur radia operation. remove the cable control and test run the crane).
If you are not satisfied with any direction/directions, repeat these. See item 1.
