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. Remove dirt and metal shavings.
2. Check enclosure for damage.
3. Check for tight installation of the sensor and coded actuator.
4. Check for alignment of sensor and actuator.
5. Check switching function.
Special conditions and »X« marking
A fuse according to the switching current of the sensor to IEC 60127-2
must be connected to each safety sensor. The fuse can be installed in-
side the supply device or must be connected separately. The fuse oper-
ating voltage must be as high as or higher than the maximum switch-
ing voltage of the safety sensor. The safety-technological maximum
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 a hazardous area, connect the
cable inside an enclosure which meets the requirements of an ap-
proved ignition protection type to EN IEC 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 sen-
sors and actuators. Different arrangements are possible, may lead to
different switching distances, however. The maximum possible offset
between sensor and actuator can be found in the diagram »Axial mis-
alignment«. 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 sensor and actu-
ator must be observed (opening of the safety guard). Verify the correct
function by observing the connected safety module. This also defines
the maximum switching frequency of the sensor. Do not use the device
as mechanical endstop. Any mounting position is possible. Recon-
struction and alterations to the device which might affect the explosion
protection are not allowed. EN 60079-14 has to be applied for the in-
stallation of electrical equipment in hazardous areas. The ATEX test
certificate and the enclosed special conditions have to be observed.
For the integration of the device in the entire system: strictly observe
and respect the control category determined in the risk assessment.
Therefore, a validation according to EN ISO 13849-2 or EN 62061 is
necessary. Furthermore, the Performance Level according to EN ISO
13849-1 and SIL CL Level according to EN 62061 can be lower than
the single level because of the combination of several safety compo-
nents and other safety-related devices, e.g. by serial connection of
sensors. It is the responsibility of the manufacturer of a plant or ma-
chine to guarantee the correct general function. Subject to technical
modifications.

Solution
Align the device correctly.
(See chap. »Alignment of
sensor and actuator«,
»Axial misalignment«,
p. 12.)
Allow safe switch-off
distance. (See chap.
»Switching distances to
EN IEC 60947-5-2«, p. 12.)
Install the device protected
from external magnetic
fields.
Reduce switching fre-
quency. (See technical data,
switching frequency, p. 13.)
Protect the device from
vibrations.
Replace the device.
