Safety
Before using the safety sensor, a risk assessment must be performed according to valid standards (e.g.
EN ISO 12100, EN ISO 13849
-
1, IEC 61508, EN IEC 62061). The result of the risk assessment deter
-
mines the required safety level of the safety sensor (see table 15.1). For mounting, operating and testing,
this document as well as all applicable national and international standards, regulations, rules and direc
-
tives must be observed. Relevant and supplied documents must be observed, printed out and handed to
affected persons.
Before working with the safety sensor, completely read and observe the documents applicable to your
task.
The following national and international legal regulations in particular apply for start-up, technical tests and
handling of safety sensors:
• Machinery Directive 2006/42/EC
• Low Voltage Directive 2006/95/EC
• EMC Directive 2004/108/EC
• Use of Work Equipment Directive 89/655/EEC supplemented by Directive 95/63 EC
• OSHA 1910 Subpart O
• Safety regulations
• Accident-prevention regulations and safety rules
• Betriebssicherheitsverordnung (Ordinance on Industrial Safety and Health) and employment protec
-
tion act
• Product Safety Law (ProdSG)
2.1
Approved purpose
The safety sensor protects persons or body parts at points of operation, danger zones or access points of
machines and systems.
• The safety sensor may only be used after it has been selected in accordance with the respectively
applicable instructions and relevant standards, rules and regulations regarding labor protection and
safety at work, and after it has been installed on the machine, connected, commissioned, and
checked by a competent person (see chapter 2.4).
• When selecting the safety sensor it must be ensured that its safety-related capability meets or
exceeds the required performance level PL
r
ascertained in the risk assessment (see table 15.1).
• With the access guarding function, the safety sensor detects persons only when they enter the dan
-
ger zone but cannot tell whether there are any persons inside the danger zone. For this reason, a
start/restart interlock in the safety chain is essential in this case.
• The construction of the safety sensor must not be altered. When manipulating the safety sensor, the
protective function is no longer guaranteed. Manipulating the safety sensor also voids all warranty
claims against the manufacturer of the safety sensor.
• The safety sensor must be inspected regularly by a competent person to ensure proper integration
and mounting (see chapter 2.4).
• The safety sensor must be exchanged after a maximum of 20 years. Repairs or exchange of wear
parts do not lengthen the mission time.
For safety-related information you may also contact the local authorities (e.g., industrial inspec
-
torate, employer's liability insurance association, labor inspectorate, occupational safety and
health authority).
WARNING
A running machine may result in serious injury!
Make certain that the safety sensor is correctly connected and that the protective function of the pro
-
tective device is ensured.
Make certain that, during all conversions, maintenance work and inspections, the system is securely
shut down and protected against being restarted.
