3.2 General description of Scanreco RC-400The Scanreco RC 400 remote control system has been especially developed forhydraulically driven mobile cranes and machinery. The system is a digital remotecontrol system based on an extremely advanced microprocessor technology. Years ofexhaustive and demanding testing have shown that the remote control system cancope with the roughest of environments.

The system is protected against electromagnetic and radio frequency radiation andcan be installed onto all hydraulic valve types (voltage, current pulse width, orprotocol steered) found on the market.

In its basic form the remote control system is comprised of a portable control unitwith manoeuvre levers for proportional control and switches for ON/OFF functions, acentral unit with connection cable for driving proportional electro-hydraulic slidecontrollers.

Digitally coded control information (lever deflection and switch position) is sent fromthe control unit via electric cable or via radio to the central unit. The control unit andcentral unit translate the magnitude and direction of the manoeuvre lever deflectionsand switch positions to corresponding valve function, speed and direction and thuscrane movement.

Important notice:

The Scanreco Remote control system RC-400 described in this instruction manualshould be distinguished from the similar Scanreco remote control systems RC-400 G4as the main components in these two system types product family (Portable controlunits and central units) are not compatible with each other and varies in appearanceand functionality.

3.3 The Portable Control Unit (PCU)The Portable Control Unit is impact, weather resistant, light weight and compact. Theportable control units can be with linear levers or with joysticks (see figure 3.2below).

Figure 3.2 The available range of portable control units.

No Description

1 MAXI-Joystick is available for 1-8 (Setup: 2-0-2 / 2-2-2 / 2-3-2 / 3-2-3 / 3-0-3).

2 MAXI-Linear is available for 1-8 linear levers

3 MINI-Joystick is available for 1-6 (Setup: 2-0-2 / 2-2-2).

4 MINI-Linear is available for 1-6 linear levers

The manoeuvre levers and joysticks are fully proportional and have spring return tothe zero position, i.e. a «dead-man’s-handle». The control units have a stop functionwhich will immediately stop all movement.

All manoeuvre levers/joysticks are protected with a protective frame againstunintentional activation and against mechanical damage. The control unit has multi-step micro-speed operation as standard enabling instantaneous temporary reductionof speed. It can also be equipped with a large number of switches for ON/OFFfunctions. A LED and sound signal are used to indicate such things as operating andbattery status and for a simple and diagnostic fault finding (see Figure 3.4).

3.3.1 Battery operation

A battery is located in the lower part of the control unit for radio control operationand is very simple to change.

• The effective operation time of the battery is about 8 hours on one charge.

• When the battery is approaching time for charging, the control unit beeps three(3) times as a warning and at the same time the LED starts to blink on thecontrol unit.

• The battery must 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 coldconditions. The battery is automatically charged during operation by cablecontrol.

• In order to reduce battery loading and for safety reasons, the control unit isturned off automatically, after the unit has been idle for more than approximatelyfive (5) minutes.

3.3.2 Manoeuvre levers / joystickThe control unit is comprised of manoeuvre levers for proportional control, switchesfor ON/OFF, micro-operation and stop function (see separate headings below).

3.3.3 Stop function panelThere is a red stop function switch (STOP) with a manual twist reset, a push buttonand a red LED on the control unit’s stop function panel, see figure 3.4.

The control unit is started with the spring reset push button ( )

All movement of the crane is stopped if the stop function is activated on the controlunit. The red LED indicates operating and battery status.

Figure 3.4 View of a stop function panel.

3.3.4 Changing radio channelsIt is possible to change the radio channel by quickly pressing the button markedtwice. There are 10 different radio channels to switch between by pressing thisbutton in sequence.

Important notice:

Scanreco will introduce an automatic frequency management to the RC400 systemsin end of 2009 making the above described function; chapter 3.3.4 changing radiochannels, obsolete.

The automatic frequency management ensures a more reliable radio transmissionhighly resistant to radio interference thanks to intelligent frequency hoppingtechnology automatically handling frequency changes.

The operator then no longer needs to manage radio frequency and the risk ofinterference is minimized.

This user manual is printed prior to the introduction of the automatic frequencymanagement, for further information; please consult your distributor.

3.3.6 Micro-speed control

This return spring switch can be used to reduce the operating speed in five (5) stepsfrom 100% to 60%, 50%, 40%, 30% and 20% speed by limiting the hydraulicsteering. The regulation of the function’s speed is still made over the entire leverstroke and with retained resolution.

• With impulses from the spring loaded toggle switch to the left, towards the turtle, speed reduction can be produced from 100% to 60%, 50%, 40%, 30%

and 20% steering.

• Movement of the switch to the right, towards the rabbit , will produce 100%steering once again.

• For safety reasons, a return to 100% steering can only be made if all manoeuvrelevers are in their zero positions.

• When the green LED is blinking, the Micro-speed function is activated. Thenumber of blinks indicates the operating speed as defined in the table below. Ifthe stop function is pressed on the controller unit, the controller unit will startfrom the last chosen speed.

Green LED Indication

not lit 0 to 100 % speed (normal speed)

1 blink every third second 0 to 60 % speed

2 blink every third second 0 to 50 % speed

3 blink every third second 0 to 40 % speed

4 Safety regulations and operatinginstructions

4.1 Safety regulationsThese instructions cover those special regulations which apply for remotely controlledcranes (cable or radio). The driver must be aware of the contents of these safetyregulations.

Remote controlled cranes may only be operated by trained personnel. The portablecontrol unit must never be passed over to any person who has not received trainingfor remote controlled cranes. If these instructions are not followed, serious accidentscan occur.

THE OPERATOR MUST:

• Check that the control unit matches the crane / machine which he is to operate.

• Acquaint himself with the symbols and positions for operating functions anddirections.

• Every time before starting work, check the stop function on the portablecontroller unit by doing the following:

1. Operate a crane / machine function and press the stop button on the portablecontroller unit. The crane must immediately come to a standstill. No furthercrane movements are possible.

2. If the cranes movement is not interrupted, crane operation must be stoppedimmediately and a service workshop visited.

• During operation, walk or stand at a suitable distance from the crane to be ableto get a good view of the operation. No unauthorised persons may be within thecrane’s working area.

• Be aware that it is forbidden to convey loads over himself or fellow workers.

• Release all manoeuvre levers (dead-man’s-handles) if crane movement control islost and then immediately press the stop function on the control unit and theemergency stop on the crane.

• The stop function on the control unit should always be in the depressed positionwhenever the unit is not in use. This applies even for short stoppages, forexample, if the driver wishes to move.

• After a completed run, press the stop function on the control unit and on thecrane. The control unit must be kept out of reach of unauthorised persons.

• Always report equipment faults or shortcomings to the person responsible for thecrane.

• Check that none of the safety devices have been altered or removed.

• Refer to the current regulations / instructions regarding «Personnel lifting withcranes”, “Overloading/overload protection «, «Visible signals during the operationof cranes» and «The location of cranes close to airports and high-tension powerlines».

• Be aware of any other pertinent regulations and of any local regulations whichmay apply. These are to be found in the relevant safety regulations regardingcrane transport.

• Be aware of the contents in «OPERATING INSTRUCTIONS» and the handling andmethod of working of the remote control system. See next section «Operatinginstructions».

4.2 Operating instructionsBefore operation, the driver must make himself aware of the contents in the «SAFETYREGULATIONS» for remotely controlled cranes. The driver must be aware of thefunction of all manoeuvre levers and switches.

1. For remote control: Place the central unit operational mode switch into REMOTE.

2. For manual/emergency operation: Place the central unit operational mode switchinto MANUAL. Power is now only supplied to the dump valve and the crane’sfunctions can be manoeuvred directly from the valve’s hand levers.

3. Twist up the emergency stop switches on the crane and on the control unit.

4. Cable operation: Connect the control cable between the control unit and thecentral unit (crane).

5. Radio operation: Place a newly charged battery in the control unit’s batteryholder.

5 Installation Instructions

5.1 General schematic of the RC 400When the Scanreco RC 400 is installed an electrically controlled dump valve must, forreasons of safety, always be connected between the manoeuvre valve and the tank.This means that during an emergency stop manoeuvre the dump valve will bewithout power and will transfer the pump flow directly to the tank thus making thesystem entirely without hydraulic pressure.

Figure 5.1

5.2 Important notice during weldingImportant: It is sometimes necessary to weld a truck/machine. During welding thesystem’s electrical connections must always be disconnected from other equipment,i.e. power supply cables (+ and -), all valve contacts, the EX cables contact must bedisconnected.

5.3 Locating the central unitImportant: The central unit must be mounted in accordance with therecommendations given below (see figure 5.2). To ensure the longest possible life forthe central unit and its cables, the central unit must always be mounted so that thevalve contacts are located facing downwards. The central unit must not be mountedso that the cables face upwards. The reason for this is to hinder water from runningvia the cables, towards the central unit

(The cables on the central unit are thus not subjected to long periods of accumulatedwater, damp, salt etc). The central unit should be mounted in a vibration freelocation and not close to strong heat sources (for example exhaust pipes etc).

7 Programming parameters and settings

7.1 General descriptionThe Scanreco RC 400 offers considerable possibilities for system constructors ofhydraulically driven mobile cranes and machines. The program in the control systemis very comprehensive, flexible and has many adaptation possibilities for specificapplications. The control system offers simple programming of a number of functionswhich can easily be turned on or off or altered during operation.

To obtain the best manoeuvre characteristics in the simplest way, all programming / calibration of manoeuvre characteristics is made during operation (so called on-line).All programming / calibration are made from the portable control unit. Programmingis simple and does not require tools / instruments.

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 levels of authorisation are divided into four main groups:

• Authorisation level 1 (Installer)

• Authorisation level 2 (Well trained installer, well trained service personnel)

• Authorisation level 3 (Well trained crane and valve manufacturer, well trainedsystem constructor)

• Authorisation level 4 (Scanreco AB, Sweden).

7.2 Authorisation level 1

7.2.1 Changing direction of movement

This describes how changes in direction of movement are made if the crane moves inthe opposite direction to that desired.

Example:

After installation and test operation it is found that the 3rd and 5th lever movementsoperate in the opposite direction to that desired. See the example below for how tochange the 3rd and 5th lever movements.

DO AS FOLLOWS

1. Remove the battery pack. Connect the cable between the Portable ControlUnit and Central Unit and test run the crane. Then press the stop button onthe Portable Control Unit and emergency stop on the crane.

2. Twist up the stop on the Portable Control Unit and on the crane.

3. Press the Portable Control Unit’s ON-button. The red LED should lightcontinuously.

4. Produce impulses in very quick succession with spring return switch MICRO toRIGHT in the OFF direction until the Portable Control Unit gives a long beepsignal. Wait approx. 12 seconds until the next long beep signal then continuewith no 5 below.

Note 1. The red LED will be extinguished each time the Portable Control Unitgives a beep signal.

Note. 2. If you do not receive the first long beep signal, start again from no 1above and execute no 3 and no 4. quicker. No 3 above and no 4. must beexecuted within max. 5 seconds.

5. Now press ON-button once.

The Portable Control Unit’s built-in beeper will give a short beep once every 5seconds to confirm that the items above have been done correctly. If anyother beep signals are heard you must restart from item 1 again. Now youcan easily change direction, see no 6 below.

6. Now you can operate the crane. Move the 3rd control lever (which isoperating in the opposite direction to that desired) and give switch MICRO animpulse to the LEFT in the ON direction.

The crane will now change direction and continue with the same selectedspeed, in the opposite direction. Do the same with the 5th manoeuvre lever.

Move the 5th manoeuvre lever (which is operating in the opposite direction tothat which is desired) and give toggle switch MICRO an impulse to the LEFT inthe ON direction. The crane will now immediately change direction andcontinue with the same selected speed in the opposite direction. If a directionchange has been made earlier for a particular lever, do the same as abovebut 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 stop button on the Portable Control Unit

Programming is now completed and the crane is operating in the directionsyou decided in item 6. For radio operation, remove the cable control and testrun the crane.

If you are not satisfied with any direction/directions, repeat the above actions.
