2.2 Applications of the non-contact
safety switch
The T4000 Multi non-contact safety switch is a
safety system which can protect movable guards,
for example, with the help of the corresponding
machine or equipment controller so that
the dangerous state of a machine or system can
only be switched on when the protective devices
are closed
or
a stop command is triggered if a protective device
is opened with the machine or system running.
For the control this means that
switch on commands that produce dangerous
states are only allowed to become effective when
the protective devices are in the protective posi-
tion
or
dangerous states must be terminated before the
protective position is left.
Prior to the use of the safety sensor, a risk assess-
ment must be performed on the machine or system
in accordance with:
EN ISO 13849-1, Safety-related parts of control
systems,
EN 14121-1, Safety of machinery, principles of
risk assessment,
EN 12100, Safety of machinery, principles of risk
assessment, basic concepts.
Correct use includes observance of the applicable
requirements on installation and operation, in parti-
cular
