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.

Function
A coded magnet safety sensor with a non-contact activation through a coded
magnet system. An elobau safety control unit or a similar safety control 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:
46311.B1. / 47011.B1 / 471EFR.. / 471M41H31 / 485EP..
NO/NC system:
46212.E1. / 462121H... / 46312.B1 / 47012.B1 / 470121H1. / 470221E1U /
471EFR.. / 485EP..

Technical specifications
See 'Technical specifications' on page 9.

Installation
- The safety sensor and switching magnet
do not use as end stops
do not install in strong magnetic fields
do not expose to any strong shocks or vibrations
keep away from iron filings
- The sensor and the accompanying switching magnets may only be mounted
in a voltage-free state.
- Ensure that the safety sensor and switching magnet markings are
congruently opposite one another.
- 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. A non-magnetic spacer with a thickness of at least 8 mm must be
used.
- The mounting distance between two sensor and switching magnet systems
must be at least 50 mm.
- Tightly fasten the safety sensor and the switching magnet to the safety
device.
- Only M4 flat head screws (e.g. M4 cylinder head screws ISO 4762) may be
used for mounting the sensor and switching magnet. Tightening torque
max. 5 Nm. Screws made from 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.

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.
10 Electrical connection
- The electrical connection is only permitted in a voltage-free state.
- Connect the safety sensor according to the specified wire colours or pin
assignment (see Technical specifications).
- Please ensure that the voltage does not fall below the required minimum
input voltage of the downstream safety processing unit. For that reason
observe the voltage drop at the sensor (series resistor) and in the connection
cable.
- For series connection of the safety sensors (verify approval in advance) their
respective NO paths must be connected in series and the respective NC
paths must be connected in parallel.
11 Commissioning
When commissioning, the following points must be ensured in advance:
- the safety sensor and switching magnet are positioned correctly and
mounted in a fixed position
- the supply line is intact
- there are no iron filings on the sensor and switching magnet
The safety sensor and the connected control unit must then be tested for
correct functionality.
12 Maintenance
If the safety sensor is mounted and used correctly, no maintenance measures
are be necessary.
We recommend a visual and functional inspection carried out at regular
intervals:
- check that the sensor and switching magnet are firmly seated
- inspect the connection cable for damage
13 Dismantling
The safety sensor may only be dismantled in a voltage-free state.
14 Disposal
Dispose of packaging and used parts in accordance with the regulations of the
country in which the device is installed.
15 Information on the manufacturing date
- 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.
The control contact is not a safety contact.
It must not be incorporated into a safety circuit.
Use the control contact for non safety-relevant signal and control
functions only.
Damaged or faulty devices must be exchanged with original
replacement parts!
The manufacturing date can be seen on the sensor casing in the
form of "calendar week/year":
e.g. "19/11“ = calendar week 19 / year 2011
