Exclusion of liability

No liability shall be accepted for any damage or 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 authorized by the
manufacturer.
No unauthorized repairs, conversions or modifications are permitted for
reasons of safety and the manufacturer shall not be liable for any damage
resulting therefrom.

Function

A coded magnetic safety sensor with a non-contact activation through a coded
actuator.
(Type 4; low coding level according to EN ISO 14119)
An elobau safety control unit or similar safety processing unit / safety controller
analyses the switching state of the safety sensor.
The safety sensors are suitable for the following elobau safety control units:

Installation

- Safety sensor and actuator
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 safety sensor and the accompanying actuators may only be mounted in
a voltage-free state.
- Ensure that all safety sensor and actuator markings are congruently
opposed to one another.
- The installation position is arbitrary. The safety sensor and actuator must
however be mounted in parallel, facing each other.
- Please note the specified installation tolerances and the approved control
options.
- Since the safety sensor is a non-embeddable proximity switch (in accor-
dance with EN 60947-5-2), the safety sensor and the actuator should be
mounted on non-ferromagnetic material. A free zone of 25 mm is required in
the event that this cannot be avoided.
- Do not attach the safety sensor and actuator to ferromagnetic material. If
necessary, use 20 mm of non-ferromagnetic material to attach the safety
sensor and actuator. The above-mentioned free zone still applies to the
safety sensor and actuator.
- Where possible, the safety sensor and actuator should not be mounted on
ferromagnetic material. Changes to the operating distances are to be
expected.

Version/Version/Version/Versione/Versión: 1.0
- The mounting distance between two safety sensor and actuator systems
must be at least 50 mm.
- Tightly fasten the safety sensor and actuator to the safety device.
- Use only screws made of non-ferromagnetic material the installation of the ac-
tuator (for example, brass countersunk screws in accordance with DIN 963).
- The safety sensor may only be mounted on an even surface as failure to do
so may lead to tension which could damage the safety sensor or alter the
operating distances.
- The connection cable of the safety sensor must be protected against me-
chanical damage.
- During the assembly process, the requirements according to EN 14119
should be taken into consideration.
- Consider the requirements of EN 60204-1 when mounting, in particular with
regard to appropriate laying. It is recommended to conceal the safety sensor
lead.

10 Adjustment

- Always test the correct functionality with one of the approved safety control
units.
- The specified operating distances (see Technical specifications) only apply
for mounting on non-ferromagnetic material and without consideration of
mounting and temperature tolerances if the safety sensor and actuator are
mounted in parallel and facing each other. Other layouts may lead to
deviating operating distances.

11 Electrical connection

- Electrical connection is permitted in voltage-free state only.
- Connect the safety sensor according to the specified wire colours or pin
assignment (see Technical specifications).
For safety sensors with male connectors, suitable cable sets and
connectors for assembly are directly available from elobau.
The control contact is not a safety contact.
It may not be incorporated into a safety circuit.
Use the control contact for non safety-relevant signal and control
functions only.
- 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 safety sensor (series resistor) and in the
connection cable.
- The voltage drop for the internal LED circuit is to be considered additionally
for LED safety sensors (see technical specifications).
If several safety sensors with LED are used, the brightness of the
LEDs can decrease with an increasing number of closed safety
doors.
- 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.

12 Commissioning

When commissioning, the following points must be ensured in advance:
- The safety sensor and actuator are positioned correctly and mounted in a
fixed position.
- The supply line is intact.
- There are no iron filings on the safety sensor and actuator.
The safety sensor and the connected control unit must then be tested for
correct functionality.

13 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 safety sensor and actuator are firmly seated.
