Quick Reference
1 Quick Reference
1.1 Tools required
• 7 mm key to fit the M4 nuts of the adjustment device.
• Allen key, size 5 for M6 screws (central attachment, X and Y adjustment)
1.2 Mounting
Attach the wall angle and place the adjustment device in the requested direction.
Tighten the M4 nuts. Do not tighten the M6 screw.
1.3 Adjustment
Make both devices alive. Bus operation is not required!
Using X and Y adjustment for a moderate distance (< 20 m):
• Find contact
--> Fast flashing of the opposite sides stops and switches to slow flashing
• Find maximum
--> Sets the bar graph display of the opposite side to maximum
Check the adjustment at maximum distance, and correct, if and when required.
The adjusted position is secured by tightening the central M6 screw.
For detailed instructions on adjustment, please refer to chapter 6.2.
1.4 Bus connections
We recommend the attachment of the screen to the screw connection of the M12 con-
nector. If this is ensured, Pin5 need not be connected. The pin assignment is printed on
the device. The M12 socket "Bus OUT/Termination" can be used to terminate the bus ca-
ble by means of a PROFIBUS terminator (cf. chapter 13 Accessories).
1.5 Setting the baud rate
Press the button for longer than a second in order to enter the baud rate adjustment
mode. If the LED of the selected baud rate is flashing, it can be changed by pressing
shortly.
(for detailed instructions, please refer to chapter 7.1 Adjusting the bus parameters).
With the locking lever pressed together, place the LS611 and release the lever.
This action can also be carried out when the cables have already been attached.

2 Validity of this instruction manual
Pepperl+Fuchs VISOLUX supplies the LS611 for two different detection ranges.
Table 2.1 Device types
Two identical LS611 devices are required for a data transmission path.
3 Scope of delivery
Check the delivery for completeness after opening the packaging.
• Optical Data Coupler LS611
• Instruction manual
• Grounding set (grounding clip and nut)
4 Principles of operation
The LS611 is a device used for serial data transmission of the PROFIBUS. The data
transmission speed varies between 93.75 kbit/s and 1.5 MBit/s.
The data are transmitted in both directions by means of modulated infrared light.
4.1 PROFIBUS data transmission
All types of PROFIBUS protocols are supported:
• PROFIBUS DP: DP-V0, DP-V1 and DP-V2 (Decentral periphery)
• PROFIBUS FMS (Fieldbus Message Specification)
• Mixed operation FMS-DP
• MPI (Multi Point Interface)
• Profisafe
In order to prevent a disturbance of the connected bus operation in case of a potential
interruption of the light beam, the "Telegram Verification Technology" (TVT) has been im-
plemented. TVT prevents the transmission of invalid telegrams. The signals are regen-
erated according to bits and characters and are sent to the bus by a crystal-controlled
process. This method ensures perfect signal conditioning. The signal quality is electrical-
ly and temporally identical with the original PROFIBUS station.
A switch-on "C1CP" function is used to prevent a collision with the master of the control
system in case of "multi-master operation".
For more information, please refer to chapter 8 "Special instructions when using several
masters".

Safety Instructions
5 Safety Instructions
The LS611 is LED operates and corresponds to the laser protection class 1 in accor-
dance with EN 60825.
If the LS611 is used as intended, the device is not cause any hazards for apparatuses
and operating staff.
6 Initial operation
6.1 Mounting
If existing adjustment and mounting facilities are to be used, M4 inserts can be pressed
into the housing foot fixtures; to be ordered as an accessory (page 27) Pos. 7.
The accessory OMH/LS610-01, a mounting aid for attachment to walls, permits a fast in-
stallation and adjustment.
Illustration 6.1 Mounting aid OMH-LS610-01 for wall attachment
The mounting aid (OMH-LS610-01) consists of a holding angle and a pre-mounted ad-
justment device (X and Y direction). The mounting aid can be used to set the requested
direction of beam (±90° rotation); the two M4 screws and the central M6 screws can be
used for the attachment to the holding angle. The central screw is used for attachment
after the adjustment, which should be tightened only after the adjustment has been com-
pleted.
Do not look into the beam from a short distance! The operating voltage has to be
provided by power supply units with safe electric isolation in accordance with EN
60742 (IEC60742). Interventions in the device are not intended and not permissi-
ble. Damaged devices shall have to be removed immediately. The connection of
the devices as well as any servicing work on them, in particular in live condition,
may be carried out by qualified experts only.

The optical data coupler's feed are placed into the recesses of the adjustment device by
pressing the two bars on the front together. The feet have to lock into place in such a way
that the bars can be pressed to the outside up to the stop; if necessary the optical data
coupler has to be pressed down applying some force from the top to the center. (cf. illus-
tration 6.2)

6.2 Adjustment
6.2.1 Alignment aid / stability control
A clearly visible alignment LED (alignment aid) has been fitted to the adjustment device.
As soon as a receiver recognizes the emitter's light of the opposite device, the flashing
frequency of the alignment aid is reduced. By going off in the end, the alignment LED in-
dicates that the devices are optimally aligned, and that sufficient stability has been en-
sured. For fine adjustment, the optical data coupler has been provided with an additional
bar graph display which permits optimal alignment.
