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 technology. 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 deflect-
ions and switch positions to corresponding valve function speed and direction and thus crane
movement.

The portable control unit is impact and weather resistant and is light weight and compact.
Controls are available for 4, 5, 6, 7 or 8 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 ).

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 unit beeps three ( 3 ) times
as a warning and at the same time the LED starts to blink on the control 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 cold conditions.
( The battery is automatically charged during operation by cable control ).
•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 approximately five ( 5 ) minutes.

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 ).
0DQ HXYUHOHYHUV
The manoeuvre levers give fully variable proportional operation and are sprung loaded to
return to zero position, i.e. "dead-man’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 title " Micro-speed control " ).

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. 9th and 10th 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" a 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.

For opto fibre control the remote control system is complemented with an opto fibre cable,
battery pack and battery charger. This means that light is used to send the control information
( not electrical impulses ).
The control unit is connected to the electronicbox via a thin opto fibre cable. The cable has
circular type contacts (Ampehenol / Hirchmann) at each end and the opto fibre electronics is
built in and integrated into the contacts.

The electronicbox is manufactured in aluminium and is provided with attachments and contacts
for connection to the portable control unit, radio receiver box and ON/OFF functions. There are
also connections and contacts for supply voltage, electro-hydraulic converter valves, slide
controls and dump valve. Since the electronicbox can be exposed to very tough environments,
the box is encapsulated to give protection from damp, heat, cold, dust, vibration and corrosive
environments. 
The electronicbox has short circuit proof inputs and outputs and has protection against polarity
reversal, over-voltage and large incoming voltage transients and EMC / RF. Connection of the
electronicbox can therefore be made without risk of damage. The electronicbox is delivered for
supply voltages of +12 / +24 VDC ( +/- 20 % ) with negative ground. There are two standard car
type fuses located inside the electronicbox.
