If serious faults occur, stop using the device. Secure the device against inadvertent operation. In the event of repairs, return the device to your local Pepperl+Fuchs representative or sales office. General Safety Information Class 1M laser product... - Page 7 LS684* Safety LS68*-DA-F2 Warning! Danger due to visible class 1M laser light If the laser light is pointed at people, especially in the dark, this can lead to irritation and result in the risk of an accident due to glare. If the laser light is viewed through optical instruments (magnifying glasses, microscopes, telescopes, or binoculars, etc.), it may damage the observer's eyes due to a burning lens effect.

Page 9: Product Description
LS684* Product Description Product Description Intended Use The optical data coupler serves as an optical link between two Ethernet devices; ideally, one of these devices is mobile. The opening angle is optimized for operations in high-rack storage. Devices in industrial Ethernet networks (e.g., with PROFINET, EtherNet/IP, and other Ethernet protocol designs) can be connected to the optical data coupler. - Page 10 LS684* Product Description Runtime compensation Real-time Ethernet systems allow cycle times in the microsecond range. Process data is synchronized throughout the system on the basis of a distributed time signal. The transmission paths between the network devices are measured for this purpose.

Status of the overall connection. Lights up in the event of errors (insufficient signal strength to establish the connection, e.g., misalignment, light beam obstructions, extra- neous light in the optical channel). - Page 13 LS684* Product Description If the optical data coupler detects an interruption on one of the sections, this information is displayed immediately with the status "Link Down" on both sides of the LS684 path via the Ethernet cable. As soon as the interruption is resolved, the cable connection on both sides will be restored.

- Page 19 LS684* Installation Assembling the mounting aid and attaching the device To assemble the mounting aid and attach the optical data coupler to the adjustment device, proceed as follows: 1. Place the adjustment device on the mounting bracket in the required direction and tighten the two M4 nuts.

LS684* Installation 6. Now perform the required adjustment. See chapter 5.1. 7. Once you have made the adjustments, tighten the central M6 fixing screw to fix the position in the horizontal direction. Connection Connecting the supply voltage The device conforms to protection class III. Note that the power must be supplied as a protective extra-low voltage (PELV) and must be limited according to UL Class 2 (100 W). -

LS684* Installation 3. Connect the other end of the grounding cable to adjacent metal components (e.g., mounting base, frame, etc.). The device is grounded. Establishing the network The M12 D-coded plug on both devices features the standard assignment for Ethernet. The optical data coupler automatically locates transmitting and receiving lines (Auto-MDIX), meaning there is no need for a crossover cable. -

LS684* Commissioning Commissioning Alignment and Adjustment Warning! Danger due to visible class 1M laser light If the laser light is pointed at people, especially in the dark, this can lead to irritation and result in the risk of an accident due to glare. If the laser light is viewed through optical instruments (magnifying glasses, microscopes, telescopes, or binoculars, etc.), it may damage the observer's eyes due to a burning lens effect. - Page 23 LS684* Commissioning Alignment aids in "unidirectional" display mode To make alignment easier, an alignment LED that is visible from far away is located on the front of the device. As soon as a receiver detects the emitted light of the device opposite it, the flashing frequency of the alignment LED decreases. When the alignment LED goes out, the devices are optimally aligned.
- Page 24 LS684* Commissioning Operating reserve In the "Operating reserve" status (green zone), the received signal strength of the optical data coupler is sufficient for operational purposes. The optical data coupler should operate in the green zone within the nominal range (at least one green LED);...

- Page 26 LS684* Commissioning Aligning using the adjustment aid The beam axis is aligned in the x and y direction using the two adjustment screws (hollow, 5 mm). This position is then fixed by tightening the central M6 fixing screw. Ethernet data communication is not needed for the alignment. Adjusting the optical data coupler The mounting aid is assembled and the optical data coupler is inserted into the adjustment device.
- Page 27 LS684* Commissioning If the alignment LED flashes again, stop turning. Now turn the adjustment screw half the number of turns in a clockwise direction to get it back to the middle. 4. To align the horizontal x-adjustment screw, proceed in the same way as described above.
- Page 28 LS684* Commissioning Note! In parallel light path arrangements, disconnecting one side of an optical data coupler is not permitted. Similarly, the light beam must not be obstructed. Parallel arrangement with distance sensors of type VDM100 The optical data coupler and distance sensors of type VDM100 can be arranged in parallel.
-
Page 29: Topology
LS684* Commissioning Topology The optical data coupler does not contain any address routing logic. As a result, the distribution of the information must always be controlled by an external network switch. The internal Ethernet adapter is permanently set to 100 MBit full duplex, as this is the only format that is converted for the optical transmission. -
