to ensure 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 de-
vice 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 correct operation of this device.
•
In case this device does not perform properly, the operator should report this to
the person 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, mask-
ing,roughening,orchangingthematerialofthereectivesurface,etc.Failureto
do so may cause the device 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uorescent
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 dangerous 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 “ 4DEVICE PLACEMENT.”
• 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 standards or regulations applicable in each region or country.
• In Japan and China, 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
immediately in the middle of an operation cycle by an emergency stop equip-
ment.
• 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.
• In case of extending the cable of the emitter or the receiver, each can be
extended up to 50m by using the exclusive cable. Extending the cable longer
than 50m may cause malfunction, which can result in death or serious injury.
• Use both control output (OSSD) and lockout output (SSD).
• In order that the output is not turned ON due to earth fault of control output
(OSSD 1 / 2), be sure to ground to 0V side (PNP output) / +24V side (NPN
output).
♦Maintenance
• When replacement parts are required, always use only genuine supplied re-
placement 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 de-
vicefollowingtheprocedurespeciedin“ 9MAINTENANCE.”
• 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.

6WIRING
WARNING
●Earth the machine or the support where the device is mounted on to frame
ground (F.G.). Failure to do so could cause the malfunction of the device by
noise, resulting in death or serious injury. Furthermore, the wiring should be done
in a metal box connected to the frame ground (F.G.).
●Take countermeasure against the system to be applied for this device so as not
to carry out the dangerous performance caused by the earth failure. Failure to do
so could cause invalid for the system stop, resulting in death or serious injury.
●In order that the output is not turned ON due to earth fault of control output
(OSSD), be sure to ground to 0V side (PNP output) / +V side (NPN output).
CAUTION
Make sure to insulate the ends of the unused lead wires.
<Reference>
Use a safety relay unit or an equivalent control circuit in safety for FSD.
●Power Supply Unit
CAUTION
Wire correctly using a power supply unit which conforms to the laws and standards
of the region where this device is to be used. If the power supply unit is non-con-
forming or the wiring is improper, it can cause damage or malfunction of this device.
<Reference>
A specialist who has the required electrical knowledge should perform the wiring.
The power supply unit must satisfy the conditions given below.
1) Power supply unit authorized in the region where this device is to be used.
2) Power supply unit SELV (safety extra low voltage) / PELV (protected extra low
voltage) conforming to EMC Directive and Low-voltage Directive.
(only for requiring CE marking conformation)
3) Power supply unit conforming to the Low-voltage Directive and with an output of
100VA or less.
4) The frame ground (F.G.) terminal must be connected to ground when using a
commercially available switching regulator.
5) Power supply unit with an output holding time of 20ms or more.
6) In case a surge is generated, take countermeasures such as connecting a surge
absorber to the origin of the surge.
7) Power supply unit corresponding to CLASS 2 (only for requiring CTÜVUS Mark
conformation).
