LT System General Rules for Implementing
26
Introduction
Before You Begin
The LT controller and related software is used to control various industrial
processes. The type or model of automation equipment suitable for each application
will vary depending on factors such as the control function required, degree of
protection required, production methods, unusual conditions, government
regulations, and so on, in some applications, more than one processor may be
required, as when backup redundancy is needed.
Only the user can be aware of all the conditions and factors present during the
setup, operation, and maintenance of the machine; therefore, only the user can
determine the automation equipment and the related safeties and interlocks that can
be properly used. When selecting automation and control equipment and related
software for a particular application, the user should refer to the applicable local and
national standards and regulations.
In some applications, additional operator protection such as point-of-operation
guarding must be provided. This is necessary if the operator’s hands and other parts
of the body are free to enter pinch points or other hazardous areas and serious injury
can occur. The LT controller and related software products alone cannot protect an
operator from injury. For this reason, this equipment cannot be substituted for or
take the place of point-of-operation protection. Ensure that appropriate safeties and
mechanical/electrical interlocks related to point of operation protection have been
installed and are operational before placing the equipment into service. All interlocks
and safeties related to point-of-operation protection must be coordinated with the
related automation equipment and software programming.
WARNING
UNGUARDED MACHINERY CAN CAUSE SERIOUS INJURY
z
Do not use this controller and related software on equipment that does not have
point-of-operation protection.
z
Do not reach into machinery during operation.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
