Safety instructions
- Ensure that the safety sensors are only mounted and put into
operation by specially-trained and authorised personnel.
- Only install and put the device into operation once you have
read and understood the operating instructions and are familiar
with the applicable regulations on occupational safety and
accident prevention.
- The safety sensor may only be activated by the switching
magnet correctly mounted to the safety device. Actuation by a
spare switching magnet that is not mounted to the safety device
is prohibited.
- The safety sensors may only be operated in a perfect
functioning condition.
- Ensure that the safety sensors are exclusively used to protect
against risks.
- Ensure that all of the valid safety regulations for the respective
machine are complied with.
- Ensure that all of the valid laws and directives are complied with.
- Connecting sensors in series can, under certain circumstances,
reduce their performance level according to EN ISO 13849-1
standards due to a lower detection of errors.
- There are no known residual risks if all of the information
contained in these operating instructions is complied with.
5
Warning against misuse
- In case of incorrect or unintended use or manipulation, the use
of the safety sensors does not exclude risks to persons or
damage to machine or system components.
Please also observe the relevant information stipulated in the
DIN EN 1088 / ISO 14119 standards.
- Please ensure that when using safety control units that have not
been supplied by elobau, no current or voltage peaks which are
higher than the specified electrical data of the safety sensor are
generated by these devices. Current or voltage peaks may for
example be generated through capacitive or inductive loads.
- An exceeding of the electrical data of the sensor (e.g. in the
event of incorrect wiring or short-circuits) may cause irreparable
damage to the sensor.
- The sensor may only be activated in the approved control
options (see 'Technical specifications').
A non-compliance with this information may result in a reduced
sensor service life.

Exclusion of liability
No liability shall be accepted for damage and operational faults caused by a
failure to observe these operating instructions. All further liability of the
manufacturer is excluded in the case of damage caused by the use of
replacement and accessory parts that have not been authorised by the
manufacturer.
No unauthorized repairs, conversions and changes are permitted for reasons
of safety and the manufacturer shall not be liable for damage resulting
therefrom.

A coded magnet safety sensor with a non-contact activation through a coded
magnet system. An elobau safety control unit or similar safety processing unit
/ safety controller analyses the switching state of the sensor.
The safety sensors are suitable for the following elobau safety control units:
2-NO system (120262..):
471M41H31
2-NO system (120V62..):
46311.B1. / 47011.B1 / 471EFR.. / 471M41H31 / 485EP..
NO-NC system (120272..):
46212.E1. / 462121H... / 46312.B1 / 47012.B1 / 470121H1. / 470221E1U /
471EFR.. / 485EP..

- The safety sensor and switching magnet
- The sensor and the accompanying switching magnets may only be mounted
in a voltage-free state.
- Make sure that the white marking of the safety sensor and the cross line of
the switching magnet face each other.
- The installation position is arbitrary. The sensor and switching magnet must
however be mounted in parallel, facing each other.
- Please note the specified installation tolerances and the approved control
options.
- Do not attach the sensor and switching magnet to ferromagnetic material. If
necessary, use 20 mm of non-ferromagnetic material to attach the sensor
and switching magnet.
- Where possible, the sensor and switching magnet should not be mounted on
ferromagnetic material. Changes to the switching distances are to be
expected.
- The mounting distance between two sensor and and switching magnet
systems must be at least 50 mm.
- Tightly fasten the safety sensor and the switching magnet to the safety
device.
- For installation of the sensor, only use the supplied fastening nuts. Max.
tightening torque 4 Nm.
- For installation of the switching magnet, suitable screws made of non-
ferromagnetic material (e.g. brass) must be used.
- The safety sensor may only be mounted on an even surface as failure to do
so may lead to tension which could damage the sensor or alter the switching
distances.
- The connection cable of the sensor must be protected against mechanical
damage.
- During the assembly process, the requirements according to DIN EN 1088 /
ISO 14119 standards should be taken into consideration.
10 Adjustment
- Always test the correct functionality with one of the approved safety control
units.
- The specified switching distances (see Technical specifications) only apply
for mounting on non-ferromagnetic material if the safety sensor and
switching magnet are mounted in parallel and facing each other. Other
layouts may lead to deviating switching distances.
