6-3. Installation
6-3-1. Drilling dimensions for mounting holes
6-3-2. Caution about the place for installation
In order not to spoil the transmitter performance, the transmitter shall not be installed in a place
where:
(1) it may be directly exposed to splashes of water, oil, dust and/or chemical,
(2) optical signals may be dampened by aqueous vapor, smoke, corrosive gas or the like (the
projector and receiver ports are made of resin and shall not be cleaned with paint thinner
based solvent),
(3) the transmitter may be exposed to temperatures, humidity, vibration and/or impact
exceeding the ratings (the transmitter shall be protected when it is continuously exposed to
vibration or impact even not exceeding the rating),
(4) a device generating a strong magnetic field, e.g. magnet or motor, or a device or power
wire generating strong noises, e.g. inverter, is used nearby,
(5) the sunlight or incandescent light containing strong infrared rays directly enters the receiver
within 10 degrees from the center of the beam path (the transmitter shall be used indoors),
(6) the beam path between the receiver and projector may be interrupted by a passing person
or obstacle or optical signals may be dampened by aqueous vapor or smoke
(communication may be suspended when the beam path is interrupted)
(7) a reflective object or beams coming from another photoelectric switch that may optically
interfere with the transmitter is located above the beam path, or
(8) the beam path to a moving unit, if used, will be inclined by 1 degree or more when the
moving unit is making a zigzag, vibrating or given an impact.

6-3-3. Intervals between adjacent pairs
When installing two or more pairs of SOT units or using a one near another photoelectric
sensor, reserve a sufficient space between them to prevent optical interferences.
Example 1
*1. This setup does not interfere with data transfer but will affect the reception level
indicated on each unit. (When adjusting the beam path or checking the
reception level, turn off the other pair of units.)
Example 2
*2. This setup does not cause interferences unless disturbed by any reflective object.
Example 3
*3. Same condition is applicable as Example 1 when the channel is different.
Caution
Note that the severity of optical interferences depends on the beam path adjustment and
misalignment factors such as vibration or impact. When installing a unit on a moving cart
or the like, adjust the beam path according to 6-5 “Beam path adjustment” and check the
performance before use to ensure normal communication throughout the whole
communication area.

(2) Recommended cable
Use a dedicated CC-Link cable.
The CC-Link system performance cannot be guaranteed if used with a cable other than
dedicated for CC-Link.
For specifications and other details of the dedicated CC-Link cable, see:
CC-Link Partner Association’s homepage: http://www.cc-link.org/

DS4-2731C
- 12 -
6-4-3. Connecting the dedicated CC-Link cables
(1) Use dedicated CC-Link cables of the same type in each segment. Using different types of
cables together does not guarantee normal data transfer.
(2) The intervals required between adjacent dedicated CC-Link cables and the maximum
extension length depend on the data transfer rate and the construction of the equipment
used. For detail, see the User’s Manual for the master unit.
(3) For the units at either ends of each segment, always connect the terminal resistor between
DA and DB. The SOT units themselves contain no terminal resistor.
Use compatible ones of the attached terminal resistors (110Ωand 130Ω) with the cable.

6-4-4. Measures to be taken to comply with the EMC Directive
The measures to be taken to ensure conformity of this optical transmission device with the EMC
Directive are described below.
To ensure conformity of the entire CC-Link system with the EMC Directive, it is necessary to take
all the necessary measures for the peripheral devices, such as the slave unit and power supply,
referring to the appropriate hardware manuals for the sequencer CPU.
(1) Attaching a ferrite core to the CC-Link cable
Attach a ferrite core to the CC-Link cable in the vicinity of the optical transmission device.
This ferrite core must have attenuation characteristics equivalent to those of the TDK
ZCAT3035-1330 ferrite core.
Please note that the measures described above are deemed as the best method based on the
information on the regulatory requirements and standards that is currently available to us.
However, use of the entire system incorporating this optical transmission device after completion
of these measures does not always ensure conformance to the EMC Directive.
It is the responsibility of the system manufacturer to specify the method for ensuring conformity
of the entire system with the EMC Directive and make a final decision on its compliance.

6-5. Beam path adjustment
A data link error occurs during beam path adjustment.
Before starting, remove the cable from the connector or check that no trouble will be caused if a
data link error occurs.
(1) After ensuring correct wiring, turn on the SOT units.
The power indicator (POW) on each unit shows red.
(2) Loosen the unit and fitting mounting screws and move the unit in every direction until the
clear data indicator (CD) on the opposite unit shows red.
Note: The opposite station reception level indicator on the unit only lights when the
monitoring function is used and the reception level at the station is CD or higher.
First, adjust while checking the reception level indicated on the opposite unit.
(3) Finely adjust until the reception level indicator on the opposite unit shows green at level 3 or
higher. The accurate reception level can be measured with a tester connected to the check
terminals on the opposite unit.
Use the DC voltage range of a tester with an input resistance of 10kΩ/V around 10V.
Insert φ2 tester probes into the (+) and (-) check terminals.
(4) The maximum voltage at the check terminals shall be 4.2V.
As a guide, the voltage shall be 2.2V or higher at the maximum transmission distance and
fixed nearly around the maximum level.
(5) Adjust the opposite unit in the same manner.
(6) When installing a unit on a moving object such as stacker crane, check that the reception
level indicators on both the moving and fixed units show green at level 3 or higher
throughout the entire region of motion.
(7) The communication error indicator (ERR) shows red when disturbed by reflected or ambient
light. When installing a unit on a moving object such as stacker crane, check that the
communication error indicators on both the fixed and moving units will not show or blink red
throughout the entire region of motion.
6-6. Monitoring function
The monitoring function communicates the reception status of each SOT unit to the master
station.
When using the monitoring function, it is necessary to specify the station number and set
parameters as remote I/O station.

8. Inspection and maintenance 
(1) Periodically check the front cover for contamination.
The product optically transmits data and may malfunction if the front cover is
contaminated. If it is heavily contaminated, wipe it clean with a dry cloth or the like.
The projector and receiver ports are made of resin and must not be cleaned with toluene
based solvent.
(2) Check for loose or chattering mounting screws and tighten, if any.
9. Caution in use 
(1) Caution about voltage ripples
Use a power supply that meets power specifications for the product.
When supplying from the power unit of a PLC (sequencer), check that the product will
normally function.
(2) Caution about the power reset
Data cannot be transmitted for about two seconds after power-up.
(3) Beam path adjustment
When installing the SOT units, never fail to adjust the beam path.
Data can be transmitted when the clear data indicator (CD) lights and the clear data
output signal (CDO) is on.
When the reception level indicator (level 1) does not light, the low reception level output
(ALM) signal is issued (off).
(4) Power wiring
The power cable length shall not exceed 50m.
Electric noises in various forms are induced into the power cable from electric
appliances on the power circuit and power cables coming from other equipment. They
may cause the units to malfunction even if the power cable is shorter than 50m.
In case the power cable wiring circuit has such disturbing factors:
(1) install the power unit nearby,
(2) shorten or separately wire the power cable, or
(3) use a cable shielded from electromagnetic fields.
