On safety
This chapter deals with your own safety and the safety of the equipment operators.
b
Please read this chapter carefully before working with the i17S or with the
machine protected by the i17S.
The national/international rules and regulations apply to the installation, commission‐
ing, use and periodic technical inspections of the safety switches, in particular
•
the Machinery Directive,
•
the Low Voltage Directive,
•
the Work Equipment Directive,
•
the safety regulations as well as
•
the work safety regulations/safety rules.
Manufacturers and operators of the machine on which the protective devices are used
are responsible for obtaining and observing all applicable safety regulations and rules.
2.1
Qualified safety personnel
The i17S safety switch must be mounted, installed and commissioned only by qualified
safety personnel. Qualified safety personnel are defined as persons who
•
have undergone the appropriate technical training
and
•
have been instructed by the responsible machine owner in the operation of the
machine and the current valid safety guidelines
and
•
who have access to these operating instructions.
2.2
Applications of the safety switches
Safety switches of the i17S series are electromagnetic switching devices.
They secure moving protective devices with a guard function so that
•
the dangerous state of the machine can only be switched on when the guard is
closed,
•
a STOP command is triggered if the protective device is opened while the machine
is operating.
For the control this means that
•
activation commands that cause dangerous conditions, may only become active
when the guard is in the protective position and the dangerous conditions have
been terminated before the protective position is cancelled.
Prior to the use of safety switches, a risk assessment must be performed on the
machine.
WARNING
If the safety switches are connected in series the Performance Level (PL) may be
reduced due to reduced fault detection, depending on the application (ISO/TR 24119).
