Safety Precautions
Refer to
Warranty and Limitations of Liability
.
This product is not designed or rated for ensuring
safety of persons. Do not use it for such purpose.
To ensure safe use of laser products, do not allow the
laser beam to enter your eye. Direct exposure may
adversely affect your eyesight.
Do not connect an AC power supply to the Sensor.
If AC power (100 VAC or more) is supplied to the
Sensor, it may explode or burn.
Be sure to abide by the following precautions for the safe operation of
the Sensor.
●
Operating Environment
Do not use the Sensor in locations with explosive or flammable gas.
●
Wiring
Power Supply Voltage and Output Load Power Supply
Voltage
Make sure that the power supply to the Sensor is within the rated
voltage range. If a voltage exceeding the rated voltage range is
supplied to the Sensor, it may explode or burn.
Power Supply Voltage
The maximum power supply voltage is 26.4 VDC. Applying a voltage
exceeding the rated range may damage the Sensor or cause burning.
Load
Do not use a load that exceeds the rated load.
Load Short-circuiting
Do not short-circuit the load, otherwise the Sensor may be damaged
or it may burn.
Connection without Load
Do not connect the power supply to the Sensor with no load
connected, otherwise the internal elements may explode or burn.
Always connect a load when wiring.
Do not use the product in atmospheres or environments that exceed
product ratings.
●
Laser Warning Labels
Be sure that the correct laser warning label (enclosed) is attached for
the country of intended use of the equipment containing the
Photoelectric Sensor. Refer to the user's manual for details.
●
Usage Environment
Water Resistance
The Sensor is rated IP67. Do not use it in water, in the rain, or
outdoors.
Ambient Environment
Do not install the product in the following locations. Doing so may
result in product failure or malfunction.
•
Locations subject to excess dust and dirt
•
Locations subject to direct sunlight
•
Locations subject to corrosive gas
•
Locations subject to organic solvents
•
Locations subject to shock or vibration
•
Locations subject to exposure to water, oil, or chemicals
•
Locations subject to high humidity or condensation
●
Designing
Power Reset Time
The Sensor is ready to operate 100 ms after the Sensor is turned ON.
If the load and Sensor are connected to independent power supplies
respectively, be sure to turn ON the Sensor before supplying power
to the load.
●
Wiring
Avoiding Malfunctions
If using the Sensor with an inverter or servomotor, always ground the
FG (frame ground) and G (ground) terminals, otherwise the Sensor
may malfunction.
●
Mounting
Mounting the Sensor
•
If Sensors are mounted face-to-face, make sure that the optical
axes are not in opposition to each other. Otherwise, mutual
interference may result.
•
Always install the Sensor carefully so that the aperture angle range
of the Sensor will not cause it to be directly exposed to intensive
light, such as sunlight, fluorescent light, or incandescent light.
•
Do not strike the Photoelectric Sensor with a hammer or any other
tool during the installation of the Sensor, or the Sensor will lose its
water-resistive properties.
•
Use M3 screws to mount the Sensor.
•
When mounting the case, make sure that the tightening torque
applied to each screw does not exceed 0.54 N·m.
Metal Connectors
•
Always turn OFF the power supply to the Sensor before connecting
or disconnecting the metal connector.
•
Hold the connector cover to connect or disconnect it.
If the XS3F is used, always tighten the connector cover by hand. Do
not use pliers.
If the tightening is insufficient, the degree of protection will not be
maintained and the Sensor may become loose due to vibration.
The appropriate tightening torque is 0.3 to 0.4 N·m.
If other commercially available connectors are used, follow the
recommended connector application conditions and recommended
tightening torque specifications.
