Installation and Operating Instructions
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
This publication does not include all specifications, dimensions, or any special installation
considerations. Refer to the product catalog pages for additional information.
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.
Installation of Allen-Bradley Guardmaster products
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.

Principles, Standards, and Implementation
Before installation in a safety application, perform a risk
assessment to determine whether the specifications of this
device are suitable for foreseeable operational and
environmental characteristics of the machine which is to be
controlled. Only the normally closed set of contacts are
considered safety contacts. When deploying these limit
switches in a safety system application, all applicable
standards for application should be followed. Operating
specifications must be followed. The actuator must be placed
beyond the point where Direct Opening Action occurs.
Do not use these devices to directly control a motor.

ATTENTION
Maintenance
These devices require little maintenance, but routine visual
inspection is recommended to keep foreign debris from
collecting on the exterior actuators and rollers. Removing the
operator head is not recommended as loose internal
components may be lost or improperly re-installed.
Actuation Guidelines
The method of actuation and over travel has significant
influence on the service life of the limit switch. To maximize
the service life, it is recommended to provide an actuator with
a 30° pressure angle and a surface hardness of Rc-45 max.

Wiring Diagram
Lever Positioning
Some rotary switches are supplied with levers that are
mechanically coupled to the actuating shaft. The lever may be
removed and re-installed to adjust cam tracking. See table
below for torque recommendations.
