Installation and Operating Instructions
Bulletin 440P Small Metal Safety Position Switches
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.
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.
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 ISO 13857 and ISO 13855 for guard openings and minimum (safe) distances.
Comply with IEC 62061 or ISO 13849-1 and ISO 13849-2 for functional safety.
General Data
• Safety contacts: 1 N.C.

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.

IMPORTANT
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.
EN ISO 14119 replaces EN 1088 as the harmonized standard for interlocking devices associated with guards.

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