Technical Information DFS 700 / 04.2009 2-3
otes on certain types of danger
Electrical power
( ) To connect the DFS 700 to the public power supply outdoors, a connection must be
available that satisfies the local electrical guidelines and safety requirements.
The power supply line phase brown/black wire] must be secured with a suitable
fuse, typically 4 to 6 A. Otherwise the electronics in the DFS 700 may be damaged
or destroyed in case of over-current.
When the DFS 700 is in a fixed installation, e.g. to street lights, a disconnectable
over-current protective device (max. 6A) according to EN60950 must be installed
between the power supply line and the DFS 700. For service work on the DFS 700
the power supply must be disconnected via the over-current protective device.
The over-current protective device is to be installed in accordance with the local
electrical guidelines and safety requirements. Therefore in Scandinavia, for
example, a cut out must have a 2-pole connection against grounding.
(2) The electrical connections must always be produced in accordance with the
requirements for the intended location. In the case of fixed installations the plug on the
power supply unit or the Charger may have to be removed. If the plug is still to be used,
then an adequately waterproof, weather-resistant, and properly mounted socket with
protection to the power line as specified above is to be provided.
(3) Only use fuses of the prescribed rating. In the event of faults in the power supply shut
the equipment down immediately.
(4) Work on the electrical equipment or fittings (e. g. Charger) must only be carried out by a
qualified electrician or by trained personnel under the management and supervision of a
qualified electrician in accordance with electrical engineering rules.
(5) Parts, on which tests, maintenance and repair are being carried out, must have the
power to them disconnected. The disconnected parts must be initially tested for zero
voltage then grounded and shorted. Adjacent parts with power still connected to them
must be isolated!
(6) The electrical equipment on the DFS 700 is to be checked regularly. Defects, such as
loose connections or burnt cables, must be removed immediately.
OTE

Technical Information DFS 700 / 04.2009 2-4
(7) If work is required on disconnected parts, take a second person along who can trigger a
power-down in an emergency.
(8) Use only insulated tools!
Power Supply Unit Box (if available)
( ) As a basic principle the Power Supply Unit box is provided for use on the DFS 700 (on
the frame or in the Battery- & Mounting Box), but can also be used separately
considering the vertical alignment when placed indoors (workshop, office) or outdoors
(next to mounting location).
(2) Do not open/disassemble the Power Supply Unit box. Completely replace damaged or
non-functioning Power Supply Unit boxes, including the two cables. This also applies to
cable damage.
Battery (if available)
( ) Do not remove the Battery pole caps. A short circuit, which can destroy the Battery, is
created by bridging the positive and negative poles with metal. There is a risk of injury as
a result of parts heating up or arcing voltages.
(2) The Battery cable and poles should be undamaged; otherwise the Battery is to be
replaced.
(3) As a basic principle charge the Battery used in the Battery- & Mounting Box using the
Charger.
(4) Only charge and discharge removed Batteries in ventilated areas, as charging causes
poisonous and flammable gases to develop. No Smoking! Keep children away!
(5) Do not cover the Battery and do not place on radiators, heaters or open fires. Avoid
contact with water.
The optional Battery- & Mounting Box is the best location for the Battery while
charging and in use.
OTE

Technical Information DFS 700 / 04.2009 2-5
(2) The Battery fluid is corrosive! On contact with skin, the eyes or clothing, wash the area
affected in plenty of water. On physical contact consult a doctor (contact with sulphuric
acid).
(3) The Battery must be recycled or properly disposed of. Disposing of the Battery in
domestic waste is prohibited.
(4) The Battery may not be beaten, disassembled, damaged, dumped or burned in an open
fire. The danger of an explosion otherwise exists.
(5) Only transport Batteries wearing eye protection and acid-resistant gloves.
(6) Only work on Batteries wearing eye protection and protective clothing.
Battery Charger (if available)
( ) The Battery Charger is exclusively approved for charging the DFS 700 Battery.
(2) As a basic principle the Charger is provided for indoor use (workshop, office) but inside
the Battery- & Mounting Box it can also be used outdoors. To avoid overheating, do not
cover the Charger during a charging cycle.
(3) The epoxy resin-filled Charger is spray-proof, but must not be immersed in water for long
periods (IP67).
(4) The mains socket or a power disconnect must be easily accessible. If an operating fault
occurs, remove the plug from the socket immediately or disconnect the power.
(5) Hazardous voltages exist inside the Charger. Do not open/dismantle the Charger. Avoid
damage.
(6) The charging cycle can cause explosive gases to develop. Avoid sparks and open
flames. Ensure there is adequate ventilation during a charging cycle. The Charger may
not be used in the immediate vicinity of combustible anaesthetic gases. The plastic
casing should not come into contact with oil or grease etc., as it can be dissolved by
chemicals and solvents.
The optional Battery- & Mounting Box is the best location for the Charger while
charging and in use.

4 Technical Description
4.1 Intended use
The DFS 700 (Figure 3- ) is used to measure and display the speeds of vehicles driving into
the radar beam. These measurements are displayed to the vehicle, recorded and can be
evaluated statistically by the user program DFS-CAS.
The monitoring of traffic speeds in flowing traffic is particularly usefull for the following traffic
zones:
•Traffic zones with particular speed limits; e.g. residential areas, inner-city areas and
building sites.
•Dangerous traffic spots, such as curves, bridges and tunnels.
•Traffic zones that have to be driven carefully, e.g. in front of hospitals, schools, bus-stops,
streets with surfaces that are dirty or produce noise.
The spray-protected DFS 700 can be used outdoors permanently independent of weather
given the appropriate power supply. As a result of the reflective sheet on the frame (Figure 3-
Item ) the DFS 700 can be easily spotted by drivers during the day and especially in the dark
due to reflection from the vehicle's headlamps. If necessary, additional information can be
attached to the reflective area of the frame (Figure 3- Item ).
4.2 Functionality
In the ready-to-use state (power supply created, switched on and initial settings made by the
user program DFS-CAS), the radar sensor (Figure 3- Item 4) measures the speed of an
approaching vehicle. The radar sensor (Figure 3- Item 4) is located in the lower field of the
central figure.
In normal operation the vehicle’s speed is displayed in LED-digits (Figure 3- Item 5) on the
speed display (Figure 3- Item 3). The colour of the digits can be set to green or red.
As a rule, speeds set as permissible are displayed in green, speeds exceeding the speed limit
in red.
The LED-digits adapt their intensity to the ambient light conditions.

Technical Information DFS 700 / 04.2009 4-2
A corresponding light sensor (Figure 3- Item 2) is located in the upper field of the central
figure.
With two independent thresholds the display can also be set to flashing and an additional
external device, e.g. a flashing warning light, can be switched on for an additional warning
The speed-display unit can store up to 00,000 measurements. If the memory is full additional
measurements will overwrite the oldest measurements first.
All the settings for operation of the speed-display unit are made using the DFS-CAS user
program. The DFS-CAS user program can be installed on a PC running the Windows XP/2000
operating system and/or on a PDA running Windows Mobile 5.0.
The connection from the display unit to the PC is created using the USB-cable supplied
(Figure 3-2 Item 7) or, after activating the supplied Bluetooth adapter (Figure 3-2 Item 6) on
the PC by wireless connection. A Bluetooth-capable PDA can also be connected wireless to
the display unit.
Where the optional GSM-Modem (Figure 3-3 Item 4) is used, additional radio communication
is possible via the GSM network (mobile communication). To that end a modem is needed in
the PC and a GSM-SIM-card (Figure 3-3 Item 4B) is required in the GSM-modem (see also
4.5).
The speed display unit has a 2 /2 LED digital display, which can display the maximum value
99. It comprises a total of 27 light segments homogenously tuned to each other ( 3
segments per number, segment for the leading ). Under optimum environmental conditions
the digits can be read at a distance of over 00 m.
The operating elements and electrical connections (see Figure 4- ) are located on the back of
the speed display unit under a two-part service cover (Figure 3- Items and 2).
The connected cables are held in place by a foam rubber seal after the service covers are in
place.
The speed display unit has passive internal ventilation provided by two add-on vents (Figure
3- Item 8). The vents must always be kept uncovered.

Technical Information DFS 700 / 04.2009 4-4
The speed display unit (Figure 3- Item 2) is attached to the frame with screws (Figure 3-
Item ). Its breakthrough on the front of the display unit is sealed with black silicone.
The frame can be changed if desired. To that end, eight securing bolts on the speed display
unit casing are to be unscrewed and the silicone seal broken. The new frame is to be bolted
through the same holes and should be sealed with black silicone again.
The optional 230V Power Supply Unit box (Figure 3- Item 7) establishes the power supply
between the mains connection ( 00 V - 240 V) and the speed display unit ( 2 V) via its two
cables. The box is maintenance-free, weather-tight and not to be opened. The two add-on
vents (Figure 3- Item 8) must always be kept free.
As a basic principle, the Power Supply Unit box is to be mounted on its mounting plate above
the speed display unit on the frame.
If required, however, the Power Supply Unit box can also be set up separately considering the
vertical alignment.
The DFS 700 is mounted on a ∅ 60 mm pole via the mounting brackets (Figure 3- Item 6).
4.3 Possible applications
The DFS 700 can be used in its standard model and with the optional accessory fittings using
different possible power supplies.
Follow installation advices and electrical connections as specified in Section 6!
•Fixed installation with permanent power supply (mains operation)
The standard model of the DFS 700 is used in a fixed location and is connected to the
public electricity supply through the Power Supply Unit.
Additionally the optional Battery- & Mounting Box can be used for this kind of installation.
•Fixed installation with Battery and mains power supply (Battery buffer mode)
The DFS 700 can be operated with the Battery and the Charger in the Battery- & Mounting
Box. In case the power supply is switched off or fails the equipment is still powered by the
Battery.
The Charger recharges the Battery when the power supply is switched on again.
•Independent Installation (Battery mode)
The DFS 700 can be powered with one or two Batteries in the Battery- & Mounting Box
independent of public power supply. Alternatively, it can also be powered by solar power,
however this is not included in the delivery package of the DFS 700 and must be obtained
from other suppliers.
•Customer-specific Design
After removing the frame (Figure 3- Item ) the speed display unit can be fitted into other
frames or cases, which are equivalent to the original parts in terms of quality
(weatherproofness, ventilation).
