Intended use

The safety sensor may only be used after it has been selected in accordance with the respectively appli-
cable 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 compe-
tent person.
When selecting the safety sensor it must be ensured that its safety-related capability meets or exceeds
the required Performance Level PL
Listed in the following table are the safety-related characteristic parameters of the SOLID-2SF-M optoelec-
tronic delivery guarding for sheet-fed printing machines.
Type in accordance with IEC/EN 61496

Mission time (T
Table 2.1:
• The safety sensor protects persons at access points or at points of operation of machines and sys-
tems.
• When mounted vertically at entry points to hazard locations, the safety sensor detects the human
body.
• 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 is mandatory.
• 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 tested regularly by competent personnel.
• 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.
2.2.1

Foreseeable misuse

In principle, the safety sensor is not suitable as a protective device in case of:
• 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
2.3

Competent personnel

Prerequisites for competent personnel:
• They have a suitable technical education.
• They know the rules and regulations for labor protection, safety at work and safety technology and
can assess the safety of the machine.
• He knows the instructions for the safety sensor and the machine.
• He has been instructed by the responsible person on the mounting and operation of the machine and
of the safety sensor.
