3.1. Symbols used
Safety-related symbols
3.2. 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!

4.1 Technical Description
The DAD 10-8P unit allows for bidirectional data transmission of 8 bit data words. A pair
of units is required to create the transmission path. One of the units is set upas the MAS-
TER(High-level atinputMaster/ Slave)and thesecond asthe SLAVE(Low-level atinput
Master / Slave).
All parallel binary control signals connected to the inputs D1 to D8 are converted into an
8 bit serial sequence. This serial data is transmitted by light beam to the receiver where
it is converted back to parallel data available at the outputs D1 to D8. Frequency shift
keying is used to provide secure transmission of the binary data. The total response time
is 3ms during which both 8 bit words are transmitted, one in each direction, in timed mul-
tiplex mode.
This provides a transmission speed of 2400 baud. A feature of the timed multiplex mode
is that the last data message is always stored at the output until the next message is
transmitted.
4.2 Action on light beam interruption:
The action required in case the light beam is interrupted can be controlled by a switch.
Switch position 1: data outputs are switched off, when the light beam is interrupted.
Switch position 2: The data received last is still available at the outputs, when the light
beam is interrupted.
4.3 Switching off the transmitter:
For operating the DAD10-8P a High-level is necessary at the ENABLE input. If the EN-
ABLE-input is at low level, the transmitter is switched off.
If the transmitter is switched off at the MASTER, the SLAVE -transmitter is also switched
off automatically. If the SLAVE is switched off, the MASTER still transmits data, that the
SLAVE receives.

4.4 In- and Outputs, receiving signals:
The inputs of the DAD10-8P are isolated by optocoupler from the other switches. The
status of data in- and output is displayed by various LEDs. A high level at the input is in-
dicated by a red LED. A green LED indicates an active output.
A yellow or green LED and the output EMPF.-ANZEIGE (receiver display) gives a suffi-
cient optical signal of receiving.
(yellow LED==> standard function reserve;
green LED ==> triple function reserve)
The SYNC-output marks at the MASTER device the times, when data input is received
(rising edge) or when the output data are valid (falling edge).
