WARNING
Failure of the safety function
w
When used outside of the defined environmental conditions, the
safety-related function of the sensor cannot be guaranteed.
u
Use only in accordance with the defined environmental
conditions (→ Technical data).
Observe the following requirements:
u
Take appropriate measures for a permanent and safe fixing (→ Installation).
u
In case of lateral damping in the area of the safe switch-off distance of < s
ao
,
the target must stay there until the safe state of the complete system is
achieved. Note the response time for safety-related faults of the sensor!
u
The safe fixing must be regularly maintained at suitable intervals (cyclical
inspection). Document maintenance actions (time, persons etc.).
u
Adhere to EN 14,119 for interlocking devices associated with guards.
u
Adhere to the principle of normally closed operation for all external safety
circuits connected to the system.
u
In case of faults within the fail-safe sensor which result in the defined safe
state: Take measures to maintain the safe state when the complete control
system continues to be operated.
u
Replace damaged units.

4 Functions and features
The device detects metal without contact.
Safety-related function SF: The safe state (output stage switched off; Logic "0") is
achieved in case of damping that is shorter than the safe switch-off distance (→ 9
Technical data).
