2 Safety
This optical data transmission system was developed, manufactured and tested in line with the applicable
safety standards. It corresponds to the state of the art.
2.1 Intended use
Devices of the DDLS500 series have been designed and developed for the optical transmission of data in
the infrared range.
Areas of application
Devices of the DDLS500 series are designed for the following areas of application:
• Data transmission between stationary and/or moving devices. The devices must – with respect to the
transmission beam spread - be positioned opposite one another without interruption. A data transmis-
sion path consists of two devices designated with "FrequencyF3" and "FrequencyF4".
• Data transmission between two mutually opposing devices, whereby each device can rotate 360°. The
middle axes of the receiver lenses must – with respect to the transmission beam spread – be posi-
tioned opposite one another without interruption during the rotation.
For rotary transmission, a minimum distance of 500mm is necessary between the two devices.
NOTICE
For information about possible restrictions regarding the transmission of special protocols see
chapter 3.1.2 "Performance characteristics and delivery options".
CAUTION
Observe intended use!
The protection of personnel and the device cannot be guaranteed if the device is operated in a
manner not complying with its intended use.
ÄOnly operate the device in accordance with its intended use.
ÄLeuzeelectronicGmbH+Co.KG is not liable for damages caused by improper use.
ÄRead these operating instructions before commissioning the device. Knowledge of the
operating instructions is an element of proper use.
NOTICE
Comply with conditions and regulations!
ÄObserve the locally applicable legal regulations and the rules of the employer's liability
insurance association.
2.2 Foreseeable misuse
Any use other than that defined under "Intended use" or which goes beyond that use is considered im-
proper use.
In particular, use of the device is not permitted in the following cases:
• in rooms with explosive atmospheres
• for medical purposes
NOTICE
Do not modify or otherwise interfere with the device!
ÄDo not carry out modifications or otherwise interfere with the device. The device must not be
tampered with and must not be changed in any way.
ÄThe device must not be opened. There are no user-serviceable parts inside.
ÄRepairs must only be performed by Leuze electronic GmbH + Co. KG.

WARNING
MAS EtherCAT configuration activated on slave side!
If the MAS EtherCAT configuration is incorrectly activated on the slave side, it may result in an
overflow of the Lost Frames counter of the EtherCAT control.
With the overflow of the Lost Frames counter, all network communication on the EtherCAT
master side is deactivated.
ÄAll sensors and actuators that are operated on the affected EtherCAT master can no longer
be controlled.
ÄIn the case of moving machine or system parts, an emergency stop can result in property
damage and personal injury.
ÄLeuzeelectronicGmbH+Co.KG accepts no liability if the installation and mounting regula-
tions are not observed.
NOTICE
If the MAS EtherCAT configuration is incorrectly activated on the slave side, it may result in an
overflow of the Lost Frames counter, particularly in the following cases:
ÄThe supply voltage of the device on the master side and/or on the slave side is switched off.
ÄThe EtherCAT link of the participants directly connected to the devices is interrupted.
ÄThe optical link between the data transmission devices is interrupted.
In automatic operation, interruption of the optical link can result from incorrect alignment of
the two devices with respect to one another.
2.3 Competent persons
Connection, mounting, commissioning and adjustment of the device must only be carried out by competent
persons.
Prerequisites for competent persons:
• They have a suitable technical education.
• They are familiar with the rules and regulations for occupational safety and safety at work.
• They are familiar with the operating instructions for the device.
• They have been instructed by the responsible person on the mounting and operation of the device.
Certified electricians
Electrical work must be carried out by a certified electrician.
Due to their technical training, knowledge and experience as well as their familiarity with relevant standards
and regulations, certified electricians are able to perform work on electrical systems and independently de-
tect possible dangers.
In Germany, certified electricians must fulfill the requirements of accident-prevention regulations DGUV
(German Social Accident Insurance) provision 3 (e.g. electrician foreman). In other countries, there are re-
spective regulations that must be observed.
2.4 Disclaimer
LeuzeelectronicGmbH+Co.KG is not liable in the following cases:
• The device is not being used properly.
• Reasonably foreseeable misuse is not taken into account.
• Mounting and electrical connection are not properly performed.
• Changes (e.g., constructional) are made to the device.

2.5 Laser safety notices
Laser diode of the transmitter – laser class 1M
ATTENTION
INVISIBLE LASER RADIATION – CLASS 1M LASER PRODUCT
Do not expose users of telescopic optics!
The device satisfies the requirements of IEC/EN60825-1:2014 safety regulations for a product
of laser class1M and complies with 21 CFR 1040.10 except for conformance with IEC 60825-1
Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019.
ÄLooking into the beam path for extended periods using telescope optics may damage the
eye's retina. Never look using telescope optics into the laser beam or in the direction of re-
flecting beams.
ÄCAUTION! Use of controls or adjustments or performance of procedures other than speci-
fied herein may result in hazardous light exposure.
The use of optical instruments or devices (e.g., magnifying glasses, binoculars) with the
product will increase eye danger.
ÄObserve the applicable statutory and local laser protection regulations.
ÄThe device must not be tampered with and must not be changed in any way.
There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
The device emits invisible laser radiation with a wavelength of 785nm (device with designation
"FrequencyF3") or 852nm (device with designation "FrequencyF4") through the laser aperture of the
optical window. The beam spread of the beam cone is ≤1° (± 0.5°).
The power density distribution in the light spot is homogeneous; there is no elevation of power density in
the center of the light spot. The average emitted laser power of the device is <12mW. For transmission of
the data, the emitted laser radiation is amplitude modulated (on-off keying). Pulses and pulse pauses of the
emitted laser light are between 8ns and 32ns long. The laser power emitted during the pulses is <24mW.
