Service, maintenance, repair

=
DANGER
Live parts. Electric shock hazard! Do not repair de-
fective or damaged devices. Replace them.
=
DANGER
Explosive atmosphere. Risk of burns! Do not re-
build or modify the device in any way.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check switching function.
2. Check for tight installation of the sensor and coded actuator.
3. Check for alignment of sensor and actuator.
4. Remove dirt and metal shavings.
5. Check enclosure for damage.
Special conditions and »X« marking
A fuse according to the switching current of the sensor to IEC 60127-
1-2 must be connected to each safety sensor. The fuse can be installed
inside the supply device or must be connected separately. The fuse op-
erating voltage must be as high as or higher than the maximum
switching voltage of the safety sensor. The safety-technological maxi-
mum values of the switching currents must limited to 125 mA and
20 mA with the LED variant by additional external measurements. The
switch-off capacity of the fuse must be as high as or higher than the
maximum short-circuit current at the place of installation (normally
1,500 A).
- Lay the connection cable securely to protect it from mechanical
damage.
- If the connection is carried out within an explosive environment, con-
nect the cable inside an enclosure which meets the requirements of
an approved ignition protection type per EN 60079-0.
- The maximum short circuit current I k of the supply source may not
exceed the I k value given on the product label.
N.B.
The specified switching distances refer to face-to-face mounted safety
sensors and actuators. Different arrangements are possible, may lead
to different switching distances, however. The maximum possible off-
set between actuator and sensor can be found in the diagram »Axial
misalignment«. It must be observed that protective guards like doors,
grids, etc. change their position / direction in due time because of me-
chanical wear. The switch-off distance (s ar ) between safety sensor and
actuator must be observed (opening of the safety guard). The correct
function should be verified by the connected safety monitoring module.
This also defines the maximum switching frequency of the sensor. Do
not use the sensor as mechanical endstop. Any mounting position is
possible. Reconstruction and alterations to the sensor which might af-
fect the explosion protection are not allowed. Furthermore, EN 60079-
14 has to be applied for the installation of electrical equipment in ex-
plosive areas. Moreover, the ATEX test certificate and the enclosed
special conditions have to be observed. For the integration of the de-
vice into the entire system, the control category determined in the risk
assessment must be strictly observed and respected. Therefore, a vali-
dation according to EN ISO 13849-2 or EN 62061 is necessary. Further-
more, the Performance Level according to EN ISO 13849-1 and SIL CL
Level according to EN 62061 can be lower than the single level be-
cause of the combination of several safety components and other
safety-related devices, e.g. by serial connection of sensors. It is the
responsibility of the manufacturer of a plant or machine to guarantee
the correct general function. Subject to technical modifications. steute
does not assume any liability for recommendations made or implied by
this description. New claims for guarantee, warranty or liability cannot
be derived from this document beyond the general terms and condi-
tions of delivery.
Behaviour in case of failure
No enabling signal indicated with closed protective guard. This can be
triggered by the following:
- alignment of sensor and actuator not correct
- safe switch-off distance not reached
- interference by strong external magnetic fields
- too high switching frequency
- strong shocks or vibrations that lead to actuation of the contacts
(exceeding of shock resistance)
- maximum life time of sensor has expired
