Destination and use
The safety sensors of series EEx RC Si 56 comply with the European
standards for explosion protection EN 60079-0, EN 60079-18, EN
61241-0 und EN 61241-18 and therefore are designed for the explosive
areas of zone 1 and 2 as well as zone 21 and 22 as per DIN EN 60079-
14 and EN 61241-14. The requirements of EN 61241-14 e. g. regarding
dust deposition and temperature limits must be met. The safety sen-
sor EEx RC Si 56 for safety circuits is used in safety circuits to monitor
the position of mobile safety guards to EN 1088 and EN 60947-5-3. The
EN 60947-5-3 standard is only met if the entire system consisting of
the magnetic safety sensor, the actuator and a safety monitoring mo-
dule is used.
Mounting / Wiring
The electrical connection may only be carried out by authorised per-
sonnel. They must take care that the accessibilty of actuators or spare
actuators because of the danger of manipulation is prevented. The sa-
fety sensor, as well as the actuator should be mounted on an even
surface. Please ensure that, even in case of failure, the safety sensor
cannot be moved from its position. For protection against manipulation
use oneway safety screws, Torx with pin, riveting, etc.. When mounting
actuator and sensor please observe the requirements of DIN EN 1088,
especially paragraph 5.2 and 5.7! Safety sensor and actuator should
not be fixed on ferro-magnetic material, this leads to strong changes
of the switching distances. Do not install the sensor and the actuator
in strong magnetic fields. The presence of ferromagnetic chips may
reduce sensitivity. Do not expose the components to extreme vibra-
tions and shocks. A mounting distance of min. 50 mm between two sy-
stems must be observed. Please also observe the instructions in the
standards EN 292 and EN 953.
Special requirements
A fuse according to the switching current of the sensor per 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
operating voltage must be as high as or higher than the maximum
switching voltage of the Ex safety sensor. The safety-technological ma-
ximum 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
1500 A). The connection cable has to be fixed and laid in a way that it
is protected against mechanical damages (approval condition X). The
cable must be connected inside an enclosure which meets the require-
ments of a degree of protection per EN 60079-0: 2006 and EN 61241-0:
2006, if the connection carried out within a hazardous area.
Notices
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

offset«. It must be observed that protective guards like doors, grids,
etc. change their position / direction in due time because of mechani-
cal wear. The switch-off distance (sar) between safety sensor and ac-
tuator must be more than 23 mm (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 at the sensor -
which might affect the explosion protection - are not allowed. Further-
more DIN EN 60079-14 and EN 61241-14 have to be applied for the in-
stallation of electrical equipment in explosive areas. Moreover the Atex
test certificate and the enclosed special conditions have to be obser-
ved. The described products have been developed in order to assume
safety functions as a part of an entire plant or machine. A complete
safety system normally covers sensors, monitoring modules, indicator
switches and concepts for safe disconnection. For the integration of
the safety switch in the entire system, the control category determined
in the risk assessment must be strictly observed and respected.
Therefore a validation according to
DIN EN ISO 13849-2 or DIN EN 62061. Furthermore the Performance
Level and SIL CL can be lower because of the combination of several
safety components and other safety-related devices, e.g. by serial
connection of sensors than the single level. The responsibility taken
by the manufacturer of a plant or machine implies to secure the cor-
rect general function. Subject to technical modifications. Moreover
steute does not assume any liability for recommendations made or im-
plied by this description. From this description new claims for gua-
rantee, warranty or liability cannot be derived beyond the general
terms and conditions of delivery.
Maintenance
With careful mounting as described above, only minor maintenance is
necessary. We recommend a regular maintenance in the following
steps:
1. Check for the switching function
2. Check for tight installation of the actuator and the switch
3. Remove of dirt

ennent pour l'emploi dans les atmosphères explosibles des zones 1-2
et 21-22 selon DIN EN 60079-14 et EN 61241-14. Les recommandati-
ons concernant les dépôts de poussières et températures limites
doivent être respectées, selon EN 61241-14. Le capteur de sécurité
EEx RC Si 56 est prévu pour l'utilisation dans les circuits de sécurité et
destiné à la surveillance de protecteurs mobiles selon EN 1088 et EN
60947-5-3. Seul le système complet : capteur de sécurité / actionneur
/ module de sécurité, permet de remplir les exigences de la norme EN
60947-5-3.
