Safety laser scanner safeguards large work zones

Safety laser scanner is a fast, highly effective and convenient method of providing safeguarding for industrial personnel in stationary and mobile applications over large work areas.
Allen Bradley Guardmaster's SafeZone safety laser scanner is a fast, highly effective and convenient method of providing safeguarding for industrial personnel in stationary and mobile applications over large work areas up to 6m in radius.
The SafeZone enables users to configure and protect even the most irregular shaped warning and safety zones, simply and quickly, using Windows-based click and drag software.
The SafeZone provides a two-dimensional detection zone over a 300deg angular range, detecting the access of personnel into dangerous areas and immediately stopping hazardous movement of machinery.
A safety category Type 3 device (to EN61496-1), it can be used in stationary applications for horizontal detection in a defined protection zone, in vertical applications for whole body access and on mobile safeguarding applications - typically Automated Guided Vehicles (AGVs).
The SafeZone offers the user advantage of two zones, a Safety Zone (6m radius) and a Warning Zone (7.5m radius), both of which are created within the maximum scanning range of the SafeZone using Allen Bradley Guardmaster's SCD (Safety Configuration and Diagnostics) Windows-based software.
The zones are easily configured using a PC mouse to simply click and drag points along the perimeter of the zone to match any particular contours.
The benefit of the Warning Zone is in preventing unnecessary machine stoppages and lost production.
If a person enters the warning field, the SafeZone switches a relay contact at its signal output, which can be used to provide acoustical or optical warnings.
These warning indicate that the hazardous area is to be vacated immediately, before the protective field is activated and the SafeZone unit issues a machine stop signal.
In the event that a person or object enters the protection zone, the SafeZone scanner switches two independent relay contacts, which results in an immediate switch off of the machine or machines within that zone.
Designed to provide high levels of reliability in operation, the SafeZone is mounted in a robust IP65 rated housing and is tested against both vibration and shock.
The unit is also completely eye safe, conforming to IEC 60825 Laser Class 1.
Allen-Bradley Guardmaster is a world leader in the design and manufacture of machinery interlocking and safety monitoring systems.
As a member of EJA, which is part of Rockwell Automation, Allen-Bradley Guardmaster is able to offer complete and integrated safety and control systems, including guards, safety mats and machine interlocks, all of which find application in a wide range of industries world-wide.
