9.1. Symbols used
Safety-related symbols
9.2. General safety instructions
The following basic instructions must be observed in all cases:
• The device must not be placed in service until the manual has been read and under-
stood
• The power device for generating the power supply voltage must be reliably insulated 
electrically by means of double insulation and a safety transformer according to DIN
VDE 0551 (corresponds to IEC 742).
• The device must not be used outside the specification without suitable protective mea-
sures
• No unauthorized tampering with the device is permitted
• Do not point the device directly at the sun or measure into the sun
• Do not remove the warning instructions or rating plates
The radiation emitted by a Class 1 laser is harmless. This type of laser instrument can
be operated by anyone.
The system operator is responsible for planning, assembly, commissioning, operation,
and maintenance of the system.
Installation and commissioning of all devices must only be performed by personnel spe-
cially trained for that purpose.
The protection of the system and operating personnel is not ensured if the module is not
used according to its intended purpose.
Observe the applicable laws and regulations for use and for the intended purpose. The
devices are only approved for proper use in accordance with intended purpose. Any oth-
er use voids all warrantee claims and manufacturer's responsibility.
Use only recommended original accessories.
If you are unable to eliminate malfunctions, take the device out of operation. Secure the
device against accidental operation. Return the device to Pepperl+Fuchs for repair. Own
interventions and modifications are potentially hazardous, and any guarantee and man-
ufacturer's liability shall become void.
Dispose of the useless device in keeping with the applicable national legal regulations.
For example, you can take the sensor to the designated collection point for electronic
scrap.
Danger!
This symbol identifies an immediate and present danger.
Failure to observe this warning may result in personal injury or even
death.
In applications with shelf distances and moving carriages, care must
always be taken to observe the applicable safety regulations. Failure to
do so will result in grave danger to life and limb!

11.1 Function description
The DAD30 is an optical device for wireless serial data transmission up to 19200 bit per
second and up to 100m.
The device contains both transmitter as receiver ; so the user can rise a full duplex trans-
mission line with two devices.
All usual serial interfaces are included.
Details:
Data will be transmitted by modulated infrared/red light. To prevent undesired mutual in-
terference there are two frequency channels with centre frequencies F1 and F2.
The2-colourLED lights upred when the levelof the received signalhas reached the swit-
ching point. The data is only released for transmission after reaching this level. When 3
x the switching point has been reached, the LED lights up green, indicating sufficient
function reserve.
The DAD 30 works on the principle of Frequency Shift Keying. By means of the data, the
transmission frequency is shift keyed via the installed interface. The signal is amplified in
the receicer and led to a Phase Locked Loop (PLL) which evaluates the signal and leads
it to the interface as binary information.

Interface :
Three serial interfaces were installed: RS232, RS422/485 and 20mA current loop.
The outputs were served at once; the appropriate input must be choiced by the user
means of a switch.
In case of using current loop there are the modes active and passive switchable.
An additional switch for the optional data invertion seperately for input and output was
invented. So the user can change the data polarity in case of light beam interruption if
necessary. Normally the interrupt state will take logic high levels at the outputs (-3..15V
for RS232, for RS485 3V Difference in level (A< B) and for the current loop leading with
20mA.
Interruptions of light beam will probable corrupt the data stream.
For data blanking of the receiver there is an additional input; switching-off is signalized
by a red LED. There are also a measuring output and two function reserve outputs for
optimal alignment and control of function security.
The set up of the device will be performed by an eightfold switch inside.
