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 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 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
knowledge 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
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, masking, roughen-
ing, or changing the material of the reflective surface, etc. Failure to do so may cause
the sensor 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 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
7) Areas where the beam-receiving part of this device is directly exposed to light from
high-frequency fluorescent lamp (inverter type) or rapid starter fluorescent lamp.
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.
Do not use this device in a reflective configuration.
The corresponding emitter and receiver must have the same serial No. and be cor-
rectly oriented.
