2.1 Qualified safety personnel
The safety switch must only be installed, commissioned, and serviced by qualified
s
afety personnel. A person is authorized if he/she…
•
Has sufficient skills in the field of the power-driven machinery to be inspected
based on his/her technical training and experience
and
•
has been instructed by the machine operator in machine operation and the applic‐
able safety guidelines
and
•
Is familiar with all relevant state occupational safety regulations, work safety regu‐
lations, guidelines, and generally accepted technical rules and standards (e.g.,
DIN standards, VDE regulations, technical rules of other power-driven machinery)
to such an extent that he/she is able to evaluate the safe condition of the power-
driven machinery
and
•
Has access to and has read the operating instructions.
These are usually qualified safety personnel of the manufacturer of the protective
device or those persons who were sufficiently trained by the manufacturer of the pro‐
tective device and who are mainly tasked with testing protective devices and have been
commissioned by the operating entity of the protective device.
2.2 Intended use
The safety switch is a transponder safety switch which is activated by a non-contact
ac
tuator and is suitable for the following applications:
•
Movable physical guards
•
Safe position monitoring
The safety switch must only be used within the limits of the prescribed and specified
technical data and operating conditions at all times.
Incorrect use, improper modification or manipulation of the safety switch will invalidate
any warranty from SICK; in addition, any responsibility and liability of SICK for damage
and secondary damage caused by this is excluded.
Before using the safety switch, a risk assessment must be run on the machine.
The safety switch is not suitable for the ambient conditions such as, but not limited, to
the following:
•
Radioactivity (exception: natural radioactivity)
•
Vacuum or high pressure
•
High UV load
•
In the vicinity of low-frequency RFID devices
•
In the vicinity of magnetic fields
The following may impair the function of the safety switch:
•
Metal subsurface or metal in direct proximity (see "Mounting", page 10)
•
Passing metal chips
