WARNING
♦
Machine designer, installer, employer and operator
•
The machine designer, installer, employer and operator are solely responsible
to ensure that all applicable legal requirements relating to the installation and
the use in any application are satisfied 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 confirmed.
♦
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, mask-
ing, 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.
•
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 “
4
DEVICE PLACEMENT
.”
• Do not use this device in a reflective configuration.
•
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 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 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 specified in “
9
MAINTENANCE
.”
•
Clean this device with a clean cloth. Do not use any volatile chemicals.
♦
Others
• Never modify this device. Modification may cause the device not to detect,
resulting in death or serious injury.
• Do not use this device to detect objects flying over the sensing area.
•
Do not use this device to detect transparent objects, translucent objects or
objects smaller than the specified minimum sensing objects.
