Short product description
The light arrow is suitable for stationary and mobile use on motorways, expressways, federal and rural roads
as well as in inner-city areas. The locally applicable regulations must be observed:
in Germany RSA, TL warning lights, StVO.
The light arrow is equipped with LED lamps. It is available in three versions depending on the construction: with
electric lifting, manual lifting or fixed mounting.
Operation is done via an external remote control. The device can be used universally in 12Volt or 24V on-board
networks. LED lamp monitoring, night reduction of the lamps and deep discharge protection are integrated.
The lamp monitoring indicates a failure in the signal image, depending on the fault, by the yellow or red LED
lighting up in the remote control.
The dimming reduces the luminosity of the LED lamps depending on the ambient luminosity (to protect mo-
torists from dazzling).
The deep discharge protection switches the device off once the battery is discharged (battery protection).
The main control is located in the control box. All electrical connections are spring connected to the main
control, with the exception of the lifting actuator and power supply.
The circuit board can be removed after loosening the fixing screws, removing the spring connectors, loosening
the motor cables and supply cable.

ACOUSTIC ERROR INDICATION
At mobile warning trailers, malfunctions will also be indicated by an acoustic signal.
WIRELESS (RADIO) REMOTE CONTROL
The radio remote control contains a high quality Ni-Mh battery.
As soon as the cable is connected, it is automatically charged via the internal charge controller.
The charging time of the empty battery is about two hours. During operation, the status of the
internal battery is displayed in intervals of approx. 10 seconds in the battery condition display.
This is indicated by flashing of the LED.
Flashing green: Remaining capacity <40 %
Flashing yellow: <20 %
Flashing red: <10 %
In addition, an acoustic warning signal is emitted by the remote control when reaching its low battery capacity.
Operating time with fully charged battery approx. 10 hours (continuous operation).
In radio mode, the remote control switches off after approx. 5 minutes.
In cable mode the remote control does not switch off.
When the cable is plugged in, there is no radio communication with the control unit !
CHARGING INDICATOR (RADIO) / OPERATING STATUS INDICATOR (CABLE)
When the charging cable or data cable is plugged into the remote control during radio operation (with the
remote control and main control switched off!), the LED at the ON/OFF button lights up yellow for approx. 30
minutes. This indicates that the remote control is supplied with power and the charging device is working.
Charging continues automatically even if the yellow LED turns off.
The charging indicator can be reactivated by pressing the ON/OFF button very briefly.
This is for information purposes only!
To switch on the control unit or the remote control in this state, press and hold the
ON/OFF key pressed (see description below).
If no connection can be established, the remote control switches off automatically after a few
seconds in radio operation and after approx. 5 minutes in cable operation.
The internal charging device allows charging between a temperature of +5 C° and +60 C.
This is a technical necessity in order to ensure the long service life and operational safety of the
internal battery. However, the yellow charging indicator continues to light up yellow beyond the
temperature range as described.
CAUTION!
The socket on the remote control must be closed with the supplied protective cap when the cable
is not plugged in.
Otherwise there is a risk of water penetrating the housing and damaging the electronics.
The bayonet lock must always be closed, even when the plug with cable is plugged in.

Self-diagnosis of the main controller and the system
The controller has extensive diagnostic features. Directly after switching on and during operation, the diagno-
sis is carried out continuously.
Cable interruptions, short circuits and undefined states
Cable interruptions of the inductive end position sensors, the proximity switches of the actuators (upright,
rotary arrow or bolt motor) as well as of the lights (directional emitter and long range warning) are detected.
In addition, undefined states (e.g. both end position sensors active) are also detected and displayed accordin-
gly. In certain cases, the light arrow is switched off.
Further error indications
After switching on, in addition to the previously described defects, further malfunctions are displayed via the
LED of the remote control:
Lamps faults:
the keys „Arrow Right“, „Arrow Left“ and „Cross“ flash yellow or red if there is a cable interruption, a short

CAUTION!
The self-monitoring of the security system does however not release you from the duty to con-
stantly ensure that it is functioning properly. This is done by observing the remote control and the
indicators fitted on the housing of the main control unit.
Especially in case of a defect of the microprocessor, error states are likely to occur which do not
cause any warning by the signal horn or the remote control. If the continuous observation is not
carried out, accidents with possibly fatal results may result.
Repairs and maintenance
CAUTION!
Repair and maintenance works should generally only be carried out by qualified
personnel or if possible by the manufacturers on site
„Information for the expert /technical engineer“.
Complete breakdown
Please check:
- the battery terminals
- fuses (on-board)
- the supply voltage at the plug contacts of the main circuit board
- LED indicator lights on the control board (from right to left):
LED 1 lights up: power supply is provided
LED 1 and 2 light up together: power supply provided, CPU is switched on or active
If no error has been detected up to this point, please contact our customer service
Softwareupdate
The software of the main control unit can be installed via the USB socket.
The control unit must be disconnected from the on-board power supply beforehand.
Now connect the control unit to the computer using a standard USB-B connection.
During the update, only LED 2 lights up if no power supply is connected.
Replacing the main circuit board
- disconnect the current supply at the rechargeable battery (first the negative and then the positive pole),
- open the enclosure of the maincontrol - disconnect the power supply cable by removing the flat plugs
- disconnect the multipoint connectors on the circuit board as well as all actuators, making sure that the main
circuit board is not subject to any mechanical stress during this process! If necessary, create counter pres-
sure at the position by holding the board firmly
- loosen the fixing screws of the circuit board and remove it
The installation of the main circuit board is carried out in reverse order.

Activation and de-activation of features
By means of adding or removing cable bridges, features can be activated, respectively de-activated.
Operation without additional MS 340 advanced warning lights
When operating without additional MS340 advanced warning lamps, the input „status right“ and „PWM“ must
be connected with each other (wire bridge).
In this way the control unit recognizes, after switching on, whether additional headlights are connected and
should be controlled. In this case the third LED on the main control unit lights up permanently.
Possibly existing cable feed-through for additional MS 340 LED advanced warning lamps must be sealed
against water penetration.

Operation with additional MS 340 LED advanced warning lights
Any supplied control unit can be retrofitted with additional MS340 advanced warning lamps at any time.
For part no. 210201-15x, 210502-09x and 210501-15x a supplementary set can be ordered.
The additional advanced warning lights are going to be mounted to the lower part of the light arrow, see

Adjusting of the proximity switches (collapsible arrow)
The proximity switches are pre-mounted, but should be checked for tight fit and correct limit switching points.
The proximity switch for the position „Light arrow folded down“ is located at the fixed part of the lifting device
at the height of the mounting plate for the light arrow. It should be adjusted in such a way that it detects (LED
lights up) as soon as the hinged frame touches the rubber stops.
The proximity switch for the position „Light arrow lifted“ is positioned on the hinged frame at the height of
the pivot point. To adjust it, loosen the stop screws below the pivot point and then lift the light arrow until it is
at a right angle to the roadway in 90° position. The angle is determined by the limit switch. The stop screws
are then screwed back in again.
WARNING!
Please note that the motor has a short delay time for all settings - the lighting up of the LED in the
proximity switch does not necessarily indicate an immediate stop of the lifting process.
Mounting on roof racks (Collapsible arrow)
The base frame is bolted to the roof rack by means of vibration absorbers with additional securing straps.
The threaded pieces made of lightweight metal (enclosed in delivery) can be inserted into the crossbars of all
standard roof rack systems of rectangular shape (e.g. Tuhle, Atera, etc.)
For this purpose the crossbar has to be drilled from above, but must not be drilled through.
The distance between holes is determined by the base frame.
For the lifting device part no. 21024 two basic supports are required, for lifting device part no. 21024V three
basic supports are needed.
WARNING!
Minimum distance between the base frame of the lifting device and the roof surface is 80 mm.

Mounting on flatbed vehicles (Vertical sliding arrow)
The vertical sliding arrow has been designed in such a way that it must be adequately secured both to the
crossbars behind the driver‘s cab and to the platform floor.
For this purpose, a sufficient number of fixing holes were drilled in the frame and on the base plate.
The crossbars must be drilled from above for this purpose, but must not be drilled through. The hole spacing
is determined by the base frame.
As the position of the crossbars depends on the individual vehicle manufacturers, the operator or a vehicle
body builder must install a suitable fastening.

Adjusting the proximity switches
The proximity switches are positioned on a holder at the rear of the light arrow. Each proximity switch should
be adjusted in such a way that it detects (LED lights up) when the respective angle (welded to the frame) is in
front of the proximity switches. It is recommended to check this regularly and to readjust the proximity swit-
ches if necessary to avoid damage to the motor. However, the proximity switches must never protrude too far,
otherwise they may be sheared off by the angles.
