This chapter describes the use of pressure-sensitive protective devices
(safety mats and safe edges) with the PNOZmulti.
Please refer to the following:
 The operating manuals provided with the PNOZmulti units
 The PNOZmulti technical catalogue
 The certificate showing approved pressure-sensitive protective de-
vices
 The installation manual and user information provided by the safety
mat/safe edge manufacturer (see "Intended use").
Schaltmatte_Definition
Safety mat
A safety mat is a protective device which detects a person standing on
it or stepping on to it. The safety mat comprises a sensor which re-
sponds to the application of pressure, a control unit and an output signal
switching device.
With a safety mat, the effective sensing area is deformed locally when
the sensor is operated.
Safe edge
A safe edge is a protective device which is designed to detect contact
from a person or any part of a person's body. It comprises:
 A sensor, which generates a signal when pressure is applied to part
of its surface, whereby:
– Its length is greater than its width
– Its cross section is constant across its length
– Cross-sectional width is greater than 8 mm
– The effective sensing area is deformed locally to actuate the sensor
 A control unit that responds to a signal from the sensor and generates
an output signal that it sends to the machine control system.
