position of mobile safety guards to EN ISO 14119 (EN 1088) type 4 and
EN 60947-5-3. The EN 60947-5-3 standard is only met if the entire sys-
tem consisting of the safety sensor, the actuator and a safety monitor-
ing module is used.
Installation / Mounting / Dismantling
=
DANGER
Live parts. Explosive atmosphere. Explosion haz-
ard! Risk of burns! Ignoring this message will lead
to serious injuries or death. Connecting and discon-
necting only to be performed by qualified and au-
thorised personnel. Connecting and disconnecting
only in non-explosive atmospheres.
The magnetic sensor, as well as the actuator, should be mounted on
an even surface and oppositely according to the marks on sensor and
magnet. The electrical connection may only be carried out by author-
ised personnel. Due to the danger of manipulation: Prevent accessibil-
ity to actuators and spare actuators. Ensure that the device cannot be
moved from its position. Ensure this in case of failure, too. When
mounting actuator and sensor, please observe the requirements of
EN ISO 14119, especially paragraph 7, »Construction to reduce ma-
nipulation of interlocking devices«! For protection against manipula-
tion use oneway safety screws, Torx with pin, riveting, etc. Safety sen-
sor and actuator should not be fixed on ferro-magnetic material, this
leads to strong changes of the switching distances. Do not install the
safety sensor and the actuator in strong magnetic fields. The presence
of ferromagnetic chips may reduce sensitivity. Do not expose the safety
sensor and the actuator to extreme vibrations and shocks. Protected
wiring by cable conduit, armoured conduit or similar measures is re-
quired for the variants Ex RC Si 56 2Ö in order to avoid faults by short-
circuiting. With the variants Ex RC Si 56 1Ö/1S, monitoring of the anti-
valence is required. A mounting distance of min. 50 mm between two
systems must be observed. Depending on the electrical load, the
magnetic sensor must be protected from voltage and current peaks
by suitable protection circuits. It is required to distinguish between
ohmic, inductive and capacitive load. Observe the instructions in the
standards EN ISO 12100 and EN ISO 14120.

Application / Operation

=
DANGER
In case of overloaded contacts too high operation
temperatures. Explosion hazard! Risk of burns! Ig-
noring this message will lead to serious injuries or
death. For short-circuit protection use appropriate
fuse size.
- Use device only within the permitted electrical load limits (see tech-
nical data).
- Use device only within the permitted ambient temperature range (see
product label and technical data).
Cleaning
- Use a damp cloth to clean devices in explosive areas. This prevents
electrostatic charge.
- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Maintenance / Repair / Service
=
DANGER
Live parts. Electric shock hazard! Ignoring this
message will lead to serious injuries or death. Do
not repair defective or damaged devices. Replace
them.
=
DANGER
Explosive atmosphere. Explosion hazard! Risk of
burns! Ignoring this message will lead to serious
injuries or death. Do not rebuild or modify the de-
vice in any way.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a regular maintenance as follows:
1. Check switching function.
2. Check for tight installation of the actuator and the switch.
3. Verification of the alignment of sensor and actuator.
4. Remove dirt and swarfs.
5. Check enclosure for damage.
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 virbations that lead to actuation of the contacts (ex-
ceeding of shock resistance)
- Maximum life time of sensor has expired
Special Conditions / »X« Marking
- 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 maximum values of the switching currents
must be limited to 125 mA and 20 mA with the LED variant by addi-
tional external measurements.
