Principles, Standards, and Implementation
Operating specifications must be followed. Actuators should
be displaced beyond the point where direct opening action
occurs. If adjustable actuators become loose they may defeat
the direct opening action feature of the limit switch. These
devices are not to be used to directly control a motor.
ATTENTION To avoid electrical shock and unintended operation of
equipment, disconnect all power to the limit switch and
the controlled equipment before proceeding with any
repair or adjustment of the limit switch.
ATTENTION
Installation of Allen-Bradley limit switches should be in
accordance with local and/or national codes. Servicing
energized industrial control equipment can be
hazardous if not in accordance with recommended
safety procedures.
For safety applications, Rockwell Automation
recommends replacing the complete limit switch.
