♦ Environment
• Do not use a mobile phone or a radio phone near this device.
• If there exists a reflective surface in the place where this device is to be installed,
make sure to install this device so that reflected light from the reflective surface does
not enter into the receiver, or take countermeasures such as painting, masking,
roughening, or changing the material of the reflective 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
fluorescent lamp (inverter type), rapid starter fluorescent 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 specified
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 reflection.
• If this device is used in multiple sets, arrange them to avoid mutual interference. For
details, refer to "4. Device Placement."
• Do not use any reflection type or recursive reflection type arrangement.
• The corresponding emitter and receiver must have the same serial No. and be cor-
rectly oriented.
♦ Machine in which this device is installed
• When this device is used in the "PSDI Mode," an appropriate control circuit must be
configured 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, do not use this device as a 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 sec. 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 40.5m by using the exclusive cable. Furthermore, if the cable is extended, the
muting lamp is used, the cable of the emitter or the receiver, each can be extended
up to 30.5m by using the exclusive cable.
• Do not control the device only at one control output (OSSD 1 / 2).
• In order that the output is not turned ON due to earth fault of the control output (OSSD
1 / 2) wires, be sure to ground to 0V side (PNP output) / +V side (NPN output).
• When using this device in Korea with S-mark, be sure to ground to 0V side (PNP output).
