♦Machine designer, installer, employer and operator
●The machine designer, installer, employer and operator are solely responsible to en-
sure that all applicable legal requirements relating to the installation and the use in any
application are satised and all instructions for installation and maintenance contained in
the instruction manual are followed.
●Whether this device functions as intended to and systems including this device comply
with safety regulations depends on the appropriateness of the application, installation,
maintenance and operation. The machine designer, installer, employer and operator are
solely responsible for these items.
♦Engineer
●The engineer would be a person who is appropriately educated, has widespread knowl-
edge and experience, and can solve various problems which may arise during work,
such as a machine designer, or a person in charge of installation or operation etc.
♦Operator
●The operator should read this instruction manual thoroughly, understand its contents,
and perform operations following the procedures described in this manual for the cor-
rect operation of this device.
●In case this device does not perform properly, the operator should report this to the per-
son in charge and stop the machine operation immediately. The machine must not be
operated until correct performance of this device has been conrmed.
♦Environment
●Do not use a mobile phone or a radio phone near this device.
● If there exists a reective surface in the place where this device is to be installed, make
sure to install this device so that reected light from the reective surface does not enter
into the receiver, or take countermeasures such as painting, masking, roughening, or
changing the material of the reective surface, etc. Failure to do so may cause the de-
vice not to detect, resulting in death or serious injury.
●Do not install this device in the following environments.
1) Areas exposed to intense interference (extraneous) light such as high-frequency uo-
rescent lamp (inverter type), rapid starter uorescent lamp, stroboscopic lights or direct
sunlight.
2) Areas with high humidity where condensation is likely to occur
3) Areas exposed to corrosive or explosive gases
4) Areas exposed to vibration or shock of levels higher than that specied
5) Areas exposed to contact with water
6) Areas exposed to too much steam or dust
♦Installation
●Always keep the correctly calculated safety distance between this device and the dan-
gerous parts of the machine.
●Install extra protection structure around the machine so that the operator must pass
through the sensing area of this device to reach the dangerous parts of the machine.
●Install this device such that some part of the operator’s body always remains in the
sensing area when operator is done with the dangerous parts of the machine.
● Do not install this device at a location where it can be affected by wall reection.
●When installing multiple sets of this device, connect the sets and, if necessary, install
some barriers such that mutual interference does not occur. For details, refer to “2-3-4
Device Placement” and “3-4 Interference Prevention Function.”
● Do not use this device in a reective conguration.
●The corresponding emitter and receiver must have the same serial No. and be correctly
oriented.

♦Machine in which this device is installed
●When this device is used in the “PSDI Mode,” an appropriate control circuit must be con-
gured between this device and the machinery. For details, be sure to refer to the stan-
dards or regulations applicable in each region or country.
●In Japan and Korea, do not use this device as safety equipment for a press machine.
●Do not install this device with a machine whose operation cannot be stopped immedi-
ately in the middle of an operation cycle by an emergency stop equipment.
●This device starts the performance after 2 seconds from the power ON. Have the control
system started to function with this timing.
♦Wiring
●Be sure to carry out the wiring in the power supply OFF condition.
●All electrical wiring should conform to the regional electrical regulations and laws. The
wiring should be done by engineer(s) having the special electrical knowledge.
●Do not run the wires together with high-voltage lines or power lines or put them in the
same raceway. This can cause malfunction due to induction.
●Do not control the device only at one control output (OSSD 1 / 2).
●In order that the output is not turned to ON due to earth fault of the control output (OSSD
1 / 2) wires, be sure to ground to 0V side (PNP output) / +24V side (NPN output).
♦Maintenance
●When replacement parts are required, always use only genuine supplied replacement
parts. If substitute parts from another manufacturer are used, the device may not come
to detect, result in death or serious injury.
●The periodical inspection of this device must be performed by an engineer having the
special knowledge.
●After maintenance or adjustment, and before starting operation, test this device fol-
lowing the procedure specied in “Chapter 4 Maintenance.”
●Clean this device with a clean cloth. Do not use any volatile chemicals.
♦Others
● Never modify this device. Modication may cause the device not to detect, resulting in
death or serious injury.
● Do not use this device to detect objects ying over the sensing area.
●Do not use this device to detect transparent objects, translucent objects or objects
smaller than the specied minimum sensing objects.

Before the use of this device, construct the control system that satises the following requirements
to secure the safety of the whole system.
●To prevent the loss of the safety function due to a single fault.
Always use two types of control output (OSSD 1 / 2).
●To prevent the loss of the safety function due to the accumulation of the faults.
Construct the control system that can stop a device if discrepancy between control
outputs (OSSD 1 / 2) is detected.
<The example of the way to detect the discrepancy of control outputs>
(Example 1) Use the relay unit or the controller for the light curtain.
(Example 2) Monitor of the control outputs (OSSD 1 / 2) with the safety PLC.
(Example 3) Monitor of the contact point welding in case the safety relay is used.
If one type of control output (OSSD) is used, the auxiliary output connects to PLC to moni-
tor the operation of this device, and construct the control system that can stop a device if
discrepancy between the control output (OSSD) and the auxiliary output is detected. It is
possible to use another type of control output (OSSD) .
