2.1.1
Intended use
• The safety sensor may only be used after it has been selected in accordance with the respectively ap-
plicable 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 (Necessary competencies). The devices are designed for indoor use only.
• 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 chapter 12.1 "General
• The safety sensor protects persons or body parts at points of operation, danger zones or access points
of machines and systems.
• With the
access guarding
function, the safety sensor detects persons only when they enter the danger
zone but cannot tell whether there are any persons inside the danger zone. For this reason, a start/
restart interlock or a suitable stepping behind protection in the safety chain is essential in this case.
• Maximum permissible approach speeds (see ISO/EN ISO 13855):
• 1.6 m/s for access guarding
• 2.0 m/s for guards of points of operation
• 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 improper repair of the protective device may result in loss of the protective function. Make no re-
pairs to the device components.
• The safety sensor must be inspected regularly by a competent person to ensure proper integration and
mounting (Necessary competencies).
• The safety sensor must be exchanged after a maximum of 20 years. Repairs or the exchange of wear
parts do not extend the mission time.
2.1.2
Foreseeable misuse
Any use other than that defined under the “Approved purpose” or which goes beyond that use is consid-
ered improper use.
In principle, the safety sensor is
not
suitable as a protective device for use in the following cases:
• Danger posed by ejected objects or the spraying of hot or hazardous liquids from within the danger
zone
• Applications in explosive or easily flammable atmospheres
• Applications outdoors or submerged in water or other liquids
2.2
Necessary competencies
The safety sensor may only be configured, installed, connected, commissioned, serviced and tested in its
respective application by persons who are suitably qualified for the given task. General prerequisites for
suitably qualified persons:
• They have a suitable technical education.
• They are familiar with the relevant parts of the operating instructions for the safety sensor and the oper-
ating instructions for the machine.
Task-specific minimum requirements for competent persons:
Configuration
Specialist knowledge and experience in the selection and use of protective devices on machines as well as
the application of technical rules and the locally valid regulations on labor protection, safety at work and
safety technology.
Specialist knowledge in programming safety-related controls SRASW acc. to ISO/EN ISO 13849-1.
Mounting
Specialist knowledge and experience needed for the safe and correct installation and alignment of the
safety sensor with regard to the respective machine.
