WARNING!
Read and understand this section prior to installing a 4700 system.
A 4700 system is a general purpose presence sensing device designed to guard personnel working
around moving machinery.
Whether a specific machine application and light curtain installation complies with safety regulations
depends on the proper application, installation, maintenance and operation of the light curtain. These
items are the responsibility of the purchaser, installer and employer.
The employer is responsible for the selection and training of personnel to properly install, operate, and
maintain the machine and its safeguarding systems. A 4700 system should only be installed, verified
and maintained by a
qualified
person. A qualified person is defined as “
a person or persons who, by
possession of a recognized degree or certificate of professional training, or who, by extensive
knowledge, training or experience, has successfully demonstrated the ability to solve problems relating
to the subject matter and work
.” (ANSI B30.2-1983)
To use a 4700 series safety light curtain the following requirements must be met:
— The guarded machine
must
be able to stop anywhere in its cycle. Do not use a safety light curtain on
a press with a full-revolution clutch.
— The guarded machine must not present a hazard from flying parts.
— The guarded machine must have a consistent stopping time and adequate control mechanisms.
— Severe smoke, particulate matter and corrosives may degrade the efficiency of a safety light curtain.
Do not use a 4700 system in this type of environment.
— All applicable governmental and local rules, codes, and regulations must be satisfied. This is the
employer’s responsibility.
— All safety-related machine control elements must be designed so that a alarm in the control logic or
failure of the control circuit does not lead to a failure to danger.
— Additional guarding may be required for access to dangerous areas not covered by the 4700 series
system.
— Perform the OMRON STI test procedure at installation and after maintenance, adjustment, repair or
modification to the machine controls, tooling, dies or machine, or the 4700 series system.
— Perform only the test and repair procedures outlined in this manual.
— Follow all procedures in this manual for proper operation of the 4700 series system.
The enforcement of these requirements is beyond the control of OMRON STI. The employer has the
sole responsibility to follow the preceding requirements and any other procedures, conditions and
requirements specific to his machinery.

WARNING!
Despite inherent safe design measures, safeguarding and complementary
protective measures adopted by the user, residual risk may remain in any installation. Potential
risks are strictly under the control of the end user and may include severe injury or death.
