Important
This module is designed for use ONLY as an operating control. Where an
operating control failure would result in personal injury and/or loss of
property, it is the responsibility of the system designer or end user to add
devices (safety, limit controls) or other systems (alarm, supervisory
systems) that protect against or warn of control failure.
Solid state equipment has operational characteristics differing from those
of electromechanical equipment. ‘Application Considerations for Solid
State Controls’ (publication SGI–1.1) describes some important differences
between solid state equipment and hard wired electromechanical devices.
Because of this difference, and also because of the wide variety of uses for
solid state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application is acceptable.
In no event will Allen-Bradley Company be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.
The examples and diagrams in this manual are included solely for
illustrative purposes. Because of the many variables and requirements
associated with any particular installation, Allen-Bradley Company cannot
assume responsibility or liability for actual use based on the examples and
diagrams.
No patent liability is assumed by Allen-Bradley Company with respect to
use of information, circuits, equipment or software described in this
manual.
