(1) Mounting hole dimensions

Use the mounting fixture provided to avoid the effect of inductive noise.
(2) Caution in choosing the installation place
 Do not use the transmitter in any of the following places to keep the performance.
1) A place where water, oils, particles, dust and/or chemicals may scatter.
2) A place where aqueous vapor, fumes and/or corrosive gases may cause optical signal
attenuation.
Do not use any thinner type solvent for cleaning since the spotlight and acceptance surfaces
consist of plastics.

sensor, they shall be installed at sufficient intervals to prevent optical interference.
Note:
The optical axis deviation due to optical axis adjustment, vibration, impact, etc.
may affect the optical interference. When installing the equipment on a moving
carrier, check before use that the equipment can normally communicate throughout
the communication area after adjustment of the optical axis according to section 9

 1) When using a shield cable, connect it (braided) to FG terminal in either the
machine (optical transmitter) or external device.
 2) For power supply, use one conforming to the specification of this machine.
 3) For the load of aux. output, connect one within the output rating (30VDC, 50mA)
of this machine. When connecting any inductive load including aux. relay, attach a
diode to protect reverse voltage.
 4) As for the cables, pay attention to the following points to prevent noises or surging induction.
 a. Do not bring the cable near any of the main circuit, high-tension power supply and load wires
or bundle it together with any of them. Keep it away from any of them by 100 m or more and
wire it separately.
 b. The same applies to intermediate cables.
 c. The power and signal wires shall not be extended by more than 50 m within the same cable.
 5) As associated with the transmission through space, loss or damage of data frame could occur. For
the communication protocol in the network, use TCP, etc. applicable to re-transmission.
6) When connecting to a hub, a switching hub is recommended.

9. Adjusting of the Optical Axis
During the adjustment of optical axis, damaged data could come out of signal (Ethernet) connector.
Remove the cable from the connector, or make sure that there will be no problem if any damaged data
flows to the network, then start adjustment.
(1) After checking that wires have been correctly connected, turn on the power supply to the main unit.
The power indicator lamp (POW) shows red.
(2) Loosen the main unit mounting screws and move the main unit in the vertical and horizontal directions
until the clear data indicator lamp (CD) on the receiving unit shows red.
<Note> Reception levels at the receiving unit on the main unit will not be displayed if the own unit
reception level fails to be CD or more. First, adjust by referring to the display of reception
level on the receiving unit.
(3) Make further fine adjustment until the reception level indicator lamps on the receiving unit show green
up to LEVEL 3 or higher.
Detailed reception levels are checked by the tester connected to the check terminal of receiving unit.
Reception levels are measured by a tester (input resistance being 10 kΩ/V or higher in DC voltage
range 10V or so). Tester bars of Φ2 shall be inserted into (+) and (-) of check terminal.
(4) Max value of check terminal voltage is 4.2V or so.
In operation, fix at the position of max voltage by referring to 2.2V or higher in the case of the max
transmission distance.
(5) Adjust the receiving unit in the same manner.
(6) When installing either unit on a moving body such as a stacker crane, check that the reception level
indicator lamps up to LEVEL 3 or higher show green at both moving and fixed units across the moving
areas.

(1) The data frame to be transmitted to the receiving unit is sent as soon as it is input to this equipment
from an external device. Data equivalent to 1 frame is not accumulated inside the equipment.
(2) Data frame sent from the receiving unit is sent to an external device as soon as it is received.
(3) Functions of sending data indicator lamp (SD) and receiving data indicator lamp (RD)
 Sending data indicator lamp (SD) blinks in red when sending input is active.
 Receiving data indicator lamp (RD) blinks in green when receiving input is active.
(4)When optical path is shielded, the receive indicator lamp goes off, and no data can be
sent any longer. Reception level is not displayed, either, at the receiving unit.
(5)Functions of link indicator lamp (LINK) and full-duplex indicator lamp (FDX)
Link indicator lamp (LINK) shows green when the network connection with the external device
connected to the signal connector is normal.
Full-duplex indicator lamp (FDX) shows green when the network connection with the external
device connected to signal connector is in full-duplex mode.
(6) Aux. output operates as shown below.

12. Maintenance and Inspection
(1) Check for any stain on the front cover periodically.
The equipment optically transmits data, and stain on the front cover may cause a
communication error. Wipe off the cover with dry cloth or such if stained heavily.
The spotlight and acceptance surfaces consist of plastics. Do not use any toluene-containing
solvent for cleaning it.
(2) Check for any loose or chattering mounting screws. Re-tighten mounting screws if
necessary.
13. Caution in Use
(1)Protection from voltage ripples
Use a power supply unit that satisfies the power supply specifications for the equipment.
When supplying power from a power supply unit for PC (sequencer or such), check that the
equipment functions normally.
(2)Caution in resetting the power
Data cannot be transferred for about 500 ms after supplying power to the equipment.
(Data cannot be transferred for further 2 sec or so because of auto negotiation when such auto
negotiation is effective.)
(3)Optical axis adjustments
Do not fail to adjust optical axis after installing the equipment.
Data can be transferred as far as the clear data indicator lamp (CD) is lit and the data link output
(DL) is on. While the reception level indicator lamp (LEVEL 1) is not lit, the low reception level
signal (ALM) is issued (OFF).
(4) Power wiring
The power cable shall be 50 m or shorter.
Electric noises are induced into the power cable in various ways from electric devices along the
power cable and from power cables to other devices.
The power cable may cause a malfunction even if it is shorter than 50 m.
If any source of such a disturbance exists along the power cable, preventive actions shall be taken
including the following:
1) Keep the power unit for the equipment nearby.
2) Reduce the length of the power cable or separately install it.
3) Change the cable to an electromagnetically shielded one.
