Introduction
SAFETY PHILOSOPHY
The control system fulls stringent safety
requirements in terms of reliability and
operational safety.
The products are CE-marked and approved
in accordance with machinery directive
2006/42/EG.
The system conforms to ISO 13849-1:2006
category 3 PLd.
Olsbergs radio remote control system has been devel-
oped to provide operators with continual feedback via
its display whenever they activate a lever or button on
the hand controller. The hand controller’s standard
menu selection system utilises the display to provide
the operator with real time information about the
chosen menu, battery status, reception conditions etc.
The hand controller contains a two-way communication
radio enabling information to be sent both to it and from
it. The radio decoder contains a corresponding unit to
handle trac at the other end.
The hand controller utilises bluetooth radio and therefore
operates in the 2.4GHz band, which is a free band that
has been approved practically worldwide. This means
that no license is needed and the radio can in principle be
used everywhere including over national boundaries.
The side displays show the symbol for the function each
lever activates in the chosen menu. When the operator
changes menu, the symbols change to the functions that
become active.
The centre display provides information about which
menu has been chosen, as well as indicating the radio
reception conditions, battery status, fault information,
micro, manual extension and so on.

Controller
The hand controller is the device that the operator
uses to control his crane and his vehicle.
The hand controller has eight levers. The functions of
each lever may be the same or dierent in dierent
menus, however only one function can exist per lever
at any one time.
If a lever is faulty, or if it is deected on starting, it is
disabled. The other levers operate as usual.
Activating the micro-button enables the operator to set
the levers to 50% or 20% of normal speed thus enabling
the crane to be operated with increased precision.

Radio Decoder
The radio decoder contains one of the radio units.
The decoder translates the radio trac, consisting
of lever and button data from the hand controller,
to the CAN bus.
For safety reasons, it is extremely important that data
is not corrupted, therefor the decoder has dual micro-
processors which monitor each other to ensure accu-
racy in the translation. The controller and the decoder
must be “paired” with each other to establish a connec-
tion. A unique code is loaded and stored in each unit.
The pairing procedure is described elsewhere in this
documentation.
A relay box is normally mounted on the bottom
of the decoder. More information regarding
the relay box and its function is provided by
a separate brochure.

Getting started!
The procedure for starting the system is described below.
INSTALLING THE BATTERY
Install a fully-charged battery in the hand controller as
shown on the right. (Figure 1)
The battery must be installed correctly or the hand con-
troller will not start.
A fully-charged 1700mAh battery provides approximately
8 hours of operation.
ACTIVATING THE SYSTEM ON THE CRANE
To turn on the crane’s control unit press the on button
on the Power Display Box, PDB. The LED above the
button will then start to ash. (Figure 2)
Then press the remote control button on the PDB, the
LED above this button will light and stay on. (Figure 3)
The decoder starts when remote control operation is
selected and the decoder’s yellow LED starts to blinks.
The crane’s control unit is now ready to be connected
with the hand controller.
ACTIVATING THE CONTROLLER
To activate the hand controller pull the stop button out
by turning it clockwise. The hand controller is powered
up and starts to establish a radio link with the decoder
on the crane. While radio contact is being established a
ashing hourglass and the text “Wait” is shown on the
centre display. (Figure 4)
Remaining battery power is displayed and the signal
strength symbol ashes when radio communication is
established but the hand controller and decoder are still
exchanging connection data.
Connection time for a cold-start can be up to 5 seconds.
A cold-start occurs when the hand controller or decoder
on the crane have been o for the last 10 minutes. When
restarting within 10 minutes of turning o the hand
controller, the radio link is still established and the hand
controller is ready for use immediately.
The factory setting for the period of time the hand con-
troller maintains contact with the decoder after pressing
the stop button is 10 minutes.

RADIO LINK ESTABLISHED
When the radio connection is established the yellow
LED on the decoder shines steadily and the green
LED blinks rapidly. (Figure 5)
The hourglass symbol on the hand controller disap-
pears and the text “Wait” (Figure 4) is replaced by
“CRANE 1”. (Figure 7)
The radio signal strength is now shown without
blinking.
If the radio connection is disrupted for longer than
0.5 of a second, then “CRANE 1” is replaced by the
“RESTART” symbol and the signal strength symbol
will either disappears or start blinking. (Figure 6)
START MENU
If the hand controller has been turned o it will
always restart in “CRANE 1”. (Figure 7)

Menu system
Olsbergs hand controllers are equipped with a
menu selection system as standard. There are
three main menus which can be easily accessed
via three push buttons.
The main menus are:
the CRANE menu
the EXTRA menu
the ON-OFF menu
In each of the main menus the operator can select sub-menus
by repeatedly pressing the same button, e.g. 1-2-3 and then
back to 1 again.
As standard, up to 4 menus with 8 proportional functions
together with 12 on-o functions, can be programmed.
The system with main menus enables the operator to change
quickly from crane operation to outrigger operation and
back again.
The hand controller always restarts in menu CRANE 1.

”CRANE MENU” BUTTON
The left-hand button in the top row on the bar, facing
towards the operator. When the operator pulls out the
start button on the hand controller, it always starts in
menu CRANE 1.
Left side display Centre display Right side display

Main menu ”CRANE”, proportional functions
The sub-menus in “CRANE” mode are congured
when the crane is tted to the vehicle. The right and
left side displays show symbols representing the
functions controlled by the corresponding levers.
When the crane menu changes, the symbols and
texts change to match the functions available via the
current menu.
The symbols are stored in a symbol library. If the library does
not contain the required symbol, a description of the function
can be written instead. Only Arabic numerals and letters from
the English alphabet can be used.
Symbols and texts can be congured via the safety system if it
is an EU crane. “OS” cranes can be congured by a computer
or delivered with a default conguration set in the factory.

“EXTRA MENU” BUTTON
The centre button in the top row on
the bar facing the operator activates
the EXTRA menu.
Left side display Centre display Right side display
Main menu ”EXTRA”, proportional functions
The “EXTRA” main menu contains additional
hydraulic proportional functions that do not
belong to the crane itself, such as outriggers
front and rear, boat supports, levelling etc.
Here too, there is a symbol or text describing the function
being used; the symbol is logically positioned in relation to
the lever. Only Arabic numerals and the English alphabet
can be used in the descriptions.
The symbols and descriptions are congured in the same
way as the “CRANE” main menu and the same method is
used for stepping between the sub-menus.

The hand controller is prepared for the use of symbols
for the ON-OFF functions. Only Arabic numerals and
the English alphabet can be used in the descriptions.
Left side display Centre display Right side display
The “ON-OFF” main menu contains functions such
as start, stop and throttle.
The functions are congured at the bodybuilder.
No symbols are used for these functions at present,
instead, a description matching the respective function
and lever is shown in the display.

SIGNAL STRENGTH
The number of bars shows the signal
strength. Optimum reception is when
all the bars are lled. When the symbol
ashes the radio is connected but the
start criteria have not been met.
Centre display, view modes
The centre display is the system’s information
centre. It shows information that is not directly
related to the crane’s operation.
The symbols used for this information are described in
detail below.
The image to the right shows the appearance of the
centre display during normal radio controlled operation
of the crane.
FAULT
A symbol of a spanner is shown when the
safety system discovers a fault in the system.
MICRO
Indicates that micro operation has been
selected. Micro operation changes the
sensitivity of the levers as follows:
At full lever deection, μ50% yields 50%
of normal speed and µ20% yields 20% of
normal speed for the crane.
MAIN MENU
The text shows which main menu has been
selected while the number shows which
sub-menu of that main menu applies. The
main menus are:
CRANE, EXTRA and ON-OFF.
NOTE! The rst menu number in EXTRA
is one higher than the highest in CRANE.
ON-OFF is numbered from 1.
ADC (Automatic Duty Control)
Indicates that the ADC function is on.
BATTERY CAPACITY
The battery symbol shows the battery
power remaining. When the system starts
to blink there is only a few minutes of
operation left. Information is sent to
the safety system which can then emit a
warning signal.
If the system is run until the battery
power fails the hand controller will auto-
matically lock.
MANUAL EXTENSION
Manual extension is selected by pressing
the horn and release buttons at the same
time. The safety system acknowledges
by showing this symbol.
SERVICE
Indicates that the crane requires service.
CAGE OPERATION
Indicates that MEWP-mode (operation
from cage) has been selected.
This requires greater stability and lower
speeds for crane movement.
JDC (Jib Duty Control)
Indicates that the JDC function is on.
HDC (Hoist Duty Control)
Indicates that the HDC function is on.

JDC / HDC / MANUAL EXTENSION
When one of the above functions is selected the symbol
is enlarged (Figure 1a) for 3 seconds before returning
to its normal size (Figure 1b) so as to alert the operator
that a change has occurred.
FAULT INDICATION
An enlarged image of the fault symbol (Figure 2a)
appears and the crane stops when a critical fault is
detected. To continue, the fault must rst be con-
rmed by pressing the release button, only then will
the spanner go back to normal size. (Figure 2b)
When a non-critical fault is detected by the safety
system an enlarged image of the spanner is shown
(Figure 2a) for 3 seconds before returning to normal
size. (Figure 2b)
ERROR CODE DISPLAY
The safety system sends error codes to the hand control-
ler. By pressing the info-button on the left hand side
under the display handle (Figure 4) the centre display
changes window to show the error codes. (Figure 3)
Error codes scroll up on the display at the same rate as
the safety system sends them, once every half second.
If there are more than 6 error codes at the same time
the 6 most recent are shown.

Overload protection ”OLP”, warning signals
Figure 1
Olsbergs hand controllers can provide informa-
tion about the pressure in cylinders equipped
with pressure sensors. This information is linked
directly to each function.
The pressure is shown as a percentage of the maxi-
mum pressure permitted, furthermore it also shows
if a particular motion is prohibited or if the crane is
subject to overload protection, (OLP).
There are three types of OLP:
Crane-OLP: means that the crane is under
maximum load.
Outrigger-OLP: means that one of the outriggers
of the crane or vehicle is under
maximum load.
VSL-OLP: means that the stability limit of the
crane or vehicle has been reached.
Overload is shown on the hand controller’s displays
as follows.
CRANE-OLP
Indicated by showing 100% for those functions that
have pressure sensors in the cylinders. Any movement
that would increase the load is blocked. (Figure 1)
OUTRIGGER-OLP
Outrigger-OLP means that one of the outriggers is
under maximum load and a symbol is shown in the
centre display with the actual outrigger crossed.
At outrigger-OLP this symbol is shown irrespective
of which menu is shown in the centre display. Out-
rigger-OLP ”front left” or ”front right” are indicated
at the same spot on the symbol in the centre display.
VSL-OLP
VSL-OLP means that the stability limit of the crane/vehicle
has been reached and VSL is indicated on the centre display.
If outrigger-OLP and VSL-OLP occur at the same time, VSL
is indicated in the same symbol as the outrigger OLP.
At all types of OLP the crane/vehicle stops and all levers
must be moved to neutral position before the crane/vehicle
can be operated out of OLP position and the central display
returns to normal.

Regardless of which menu is active Outrigger – OLP
will be shown. Here outrigger-OLP ”-mid left”.

Button ”Release”
Figure 2
BLOCKING ON MAX LOAD/RELEASE
When a function has been blocked due to an OLP, a
cross is shown in the relevant lever’s display when an
attempt is made to activate it.
If the crane has got stuck the release button must be
activated to enable it to be moved from this position.
(Figure 2)
If the OLP release is accepted this is shown by an un-
locked padlock in the centre display. (Figure 3)
The crane will then operate at reduced speed for a
limited period of time.
Conguration
The hand controller must be congured specically
for the particular crane or vehicle if it is to show the
correct symbol or text.
Default settings for the crane symbols are set in the
factory during nal testing.
Conguration of other functions and tools is conducted
by the coach builder when mounting the crane on the
vehicle.
Cranes that have a safety system can utilise the termi-
nal program to congure the crane. “OS” cranes with-
out a safety system can be congured via a computer
or be adjusted in the factory.
70%
90%
WARNING AT 50%, 70%, 90% and 100%
Some of the crane’s functions are connected to pres-
sure sensors which show the pressure in these cylinders
as a percentage of maximum permitted pressure when
it exceeds 50%.
The percentage is shown as 50%, 70%, 90% or 100%
alternating with the lever’s symbol, once per second.
When a pressure sensor reaches 100% all motions
that would increase the load can be blocked. These
congurations are set by the crane manufacturer.
If the operator attempts to activate a blocked function
a cross replaces the symbol. The cross disappears and
the symbol returns when the lever is returned to the
neutral position. (Figure 4 and 5)

Locking the hand controller
- Press the EXTRA button and the ON-OFF button
when the stop button is pressed in.
- Continue to hold the buttons pressed at the same time
as the stop button is pulled out.
The centre display will now show a locked padlock.
Note!
If battery power drops too low the hand controller will
lock automatically.
Unlocking the hand controller
- Press the EXTRA button and the ON-OFF button
when the stop button is pressed in.
- Continue to hold the buttons pressed at the same time
as the stop button is pulled out.
The hand controller is ready for use.
REPLACING A HAND CONTROLLER OR DECODER
Every system has a unique controller/decoder pair which
only communicates with each other. If one unit has to be
replaced, a special procedure must be followed to make
the new pair communicate. The procedure is as follows:
1. Switch o the PDB’s system.
2. Unscrew the left-hand connector on the decoder and
remove it.
3. Connect the hand controller with the accompanying
cable (E0781) to the decoder.
4. Switch on the PDB and select “remote”.
5. Hold down the release button on the hand controller
while pulling out the stop button.
When the yellow LED on the decoder starts to blink, let
go of the release button. When the procedure is complete,
the yellow LED goes out. If the procedure was successful,
only the green LED remains lit, if not, the red LED is lit.
The procedure can take up to half a minute.
NO SIGNAL FROM THE SAFETY SYSTEM
If a fault develops in communication with the safety
system during operation, the system stops the crane. The
centre display shows the spanner symbol to indicate that
there is a fault. The crane can only be operated manually
under emergency conditions if this occurs.
LOW AMBIENT TEMPERATURE
The LCD-type displays on the hand controller are
somewhat slow in changing state in low temperatures.
At 0°C, it will take approximately 1 second, and at
-20°C it can take up to 8 seconds before the symbols
have completely updated.
For safety reasons, quick shifts within a menu are
not possible at temperatures below -10°C; though
shifting between dierent menus will still be possible
as normal.
To avoid the inconvenience that may be caused by
the above, the hand controller should be stored at a
temperature above +10°C when not in use.
LOCKING/UNLOCKING THE HAND CONTROLLER
The hand controller can be locked to prevent unauthorised
persons, such as children, from starting the hand controller
and operating the crane. (Figure 1)
17
CABLE CONTROL
The hand controller is normally used in radio mode
but it is also possible to operate it via a cable.
A four-metre cable (E0781) is supplied as standard with
the hand controller. The cable is intended to be used for
short-term operation and when pairing in conjunction
with the replacement of hand controllers or decoders.
The cable connects to the vehicle via the decoder’s left-
hand CAN bus connector. (See Figure 3)
If the hand controller is to be wired permanently or for
a long period, an adapter cable (E0837) is run from the
PDB and installed at a suitable location on the vehicle.
To give the operator greater freedom of movement, a
15-metre cable (E0782) is used between the adapter and
the controller. (See Figure 4)
When the cable is connected to the hand controller,
the centre display shows that the controller is in cable
operation mode. The symbols for signal strength (radio)
and battery capacity are replaced with the symbol for
cable operation. (See Figure 5)
Figure 4Figure 3
Figure 5
ENGAGE MANUAL EXTENSION
This function must be activated so that the safety system
can calculate the capacity when manual extension is used.
This is done by pressing the release and horn buttons at
the same time until the manual extension symbol appears
on the centre display.
Use the same procedure to disengage the manual exten-
sion function.
