Purpose and use
The safety sensor RC Si M30 Extreme is used in safety circuits to mon-
itor the position of mobile safety guards to EN ISO 14119 and EN
60947-5-3. The EN 60947-5-3 standard is only met if the entire system
consisting of the safety sensor, the actuator and a safety module.

Mounting and wiring

Mount the safety sensor and the actuator on an even surface and op-
posite each other according to the marks on the sensor and actuator.
The electrical connection may only be carried out by authorised per-
sonnel. Due to the danger of manipulation: Prevent accessibility to ac-
tuators 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, observe the requirements of EN ISO 14119, es-
pecially paragraph 7, »Construction to reduce manipulation of inter-
locking devices«! For protection against manipulation use oneway
safety screws, Torx with pin, riveting, etc. Safety sensor and actuator
should not be fixed on ferromagnetic material, this leads to strong
changes of the switching distances. Do not install the safety sensor or
the actuator in strong magnetic fields. The presence of ferromagnetic
chips may reduce sensitivity. Do not expose the components to ex-
treme vibrations and shocks. Protected wiring by cable conduit, ar-
moured conduit or similar measures is required for the variants RC Si
M30 2Ö in order to avoid faults by short-circuiting. With the variants
RC Si M30 1Ö/1S, monitoring of the antivalence is required. A mount-
ing distance of min. 50 mm between two systems must be observed.
For each safety sensor, preconnect a fitting overcurrent protection that
matches with the safety sensor's switching current, as to IEC 60127-1-
2. The fuse may be placed inside the related supply unit or has to be
preconnected separately. Depending on the electrical load, the mag-
netic 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.
N.B.
The specified switching distances refer to face-to-face mounted safety
sensors and actuators. Different arrangements are possible, but may
lead to different switching distances. The maximum possible offset be-
tween 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 (s ar ) between safety sensor and actuator
must be observed (opening of the safety guard). After wiring, a func-
tional test must be carried out by opening and closing the protective
guard. Closing of the protective guard must not lead to an automatic
start of a dangerous machine function. This may only be initiated by a
start command. The connected safety module also defines the maxi-
mum switching frequency of the sensor. The correct function should
be verified by the connected safety monitoring module. This also de-
fines the maximum switching frequency of the sensor. Do not use the
sensor as mechanical endstop. Any mounting position is possible. Re-
construction and alterations at the sensor are not allowed. For the in-
tegration of the switch into the entire system, the control category de-
termined in the risk assessment must be strictly observed and re-
spected. 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
components and other safety-related devices, e.g. by serial connec-
tion of sensors. It is the responsibility of the manufacturer of a plant or
machine to guarantee the correct general function. Subject to techni-
cal modifications. steute does not assume any liability for recommen-
dations made or implied by this description. New claims for guarantee,
warranty or liability cannot be derived from this document beyond the
general terms and conditions of delivery.

Maintenance

With careful mounting as described above, only minor maintenance is
necessary. We recommend 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.
Behaviour in case of failure
A green LED indicator is located in the lid. It lights up when both out-
put relays are switched on. In case of a malfunction, the LED will not
light up. This can be triggered by the following:
- Alignment of sensor and actuator not correct.
- Minimum switching distance not reached.
- Safe switch-off distance not reached.
- Interference caused by strong external magnetic fields.
Cleaning
- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
