Product Overview

When designed by professional personnel for use as a safety product in an
industrial environment, the MatGuard™ safety mat system provides protection
against risks that can be eliminated by the isolation of electrical power when
an operator is in the vicinity of the hazard. This manual covers the installation
and use of all components of the Allen-Bradley® MatGuard Mats system.
Only suitably trained and qualified personnel can conduct all installation
procedures, which must be in accordance with statutory requirements for
safety.
The MatGuard safety mat system is composed of a safety mat control unit, one
or more interconnected pressure sensitive safety mats, active uniting trim,
and perimeter trim, as shown in
When the system includes a suitable safety mat control unit, the control unit
detects a presence on the safety mat, a short circuit, or an open circuit. Under
each of these conditions, the safety control issues a stop command. Multiple
safety mats can combine into one safety mat system with the use of joining
trim.
