Allen-Bradley 440P Installation And Operating Instructions Manual
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.
Improper selection or installation of the devices affect the integrity of the safety
systems.
Personnel injury or death, property damage or economic loss can result.
Comply with ISO 14119 including selection, accessibility to the installation,
arrangement and fastening, possible substitute actuation, access to the escape release,
motivation to defeat, and actuation mode.
Management controls, working procedures, training, and additional protective
measures should be used to minimize the motivation to defeat and to manage the use
and availability of spare actuators.
Comply with ISO13857 and ISO13855 for guard openings and minimum (safe)
distances.
Comply with IEC 62061 or ISO 13849-1 and ISO 13849-2 for functional safety.
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.
ENISO14119 replaces EN 1088 as the harmonized standard for interlocking devices
associated with guards.

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.

Under no circumstances must the switch be actuated beyond
the mechanical travel specified. Serious damage to the device
and property could result.

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.

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
