5.2 Magnetic sensor and magnetic strip
5.3 Mechanical installation
Installation may only be carried out in accordance with the specified IP protection. If necessary the system
must be protected against environmental influences, such as sprayed water, solvent, dust, shocks, vibra-
tions, temperature fluctuations.
5.4 Installation magnetic strip
The mounting surface / measuring track must be flat. Buckles or bumps will lead to measuring inaccuracies.
For technical reasons the strip should be approx. 30mm longer than the actual measuring distance.
ATTENTION!
For an optimum of adhesion, all anti-adhesive substances (such as oil, grease, dust etc.) must
be removed by using residue-free (=evaporating) cleaners. Suitable cleansing agents are e.g.
ketones (acetone) or alcohols; Messrs.octite and 3M can both supply such cleansing liquid. Make
sure that the surface to be glued is dry and apply the stop with maximum pressure. Glueing should
preferably be undertaken at temperatures between 20° to 30° Celsius and in dry atmosphere.
INFORMATION
When applying long pieces of magnetic strip do not immediately remove the complete protective foil,
but rather peel back a short part from the end sufficient to fix the strip. Now align the strip. As the protective
strip is then peeled back and out, press the tape firmly onto the mounting surface. (a wallpaper roller wheel
could be used to assist in applying pressure onto the magnetic strip when fixing it in position)

5.4.1 Installation steps
Clean mounting surface (1) carefully.
Remove protective foil (2) from the adhesive side of the magnetic strip (3).
Stick down the magnetic strip (4).
Clean surface of magnetic strip carefully.
Remove protective foil (6) from adhesive tape on the cover strip (5).
Fix cover strip (both ends should slightly overlap).
Secure the overlapping ends of the cover against detachment .
ATTENTION!
Do not expose the system to magnetic fields. Any direct contact of the magnetic strip with
magnetic fields (e.g. adhesive magnets or other permanent magnets) is to be avoided. Sensor
movements during power loss are not captured by the follower electronics.
5.4.2 Installation examples
Mounting with chamfered ends
( Img.5-1:) is not recommended unless the strip is installed in a safe and protected place without envi-
ronmental influences. In less protected mounting places the strip may peel. In such cases are mounting
methods more suitable as shown in  Img.5-2: and
 Img.5-3:. Best protects the assembly in a groove
 Img.5-4: which should be so deep that the magnetic tape can be completely embedded therein.

5.5 Mounting the magnetic sensor
Use two M3 screws to fix the magnetic sensor. We recommend to use washers.
Cable layout should avoid damages due to cable strain or other machine parts. If necessary use a drag
chain or protective hose and provide for strain relief.
Sensor must be aligned correctly with respect to the counting direction. This can be ignored if counting
direction can be changed via the follower electronics.
Img.5-5: Definition of counting direction
Distance measurements between sensor and magnetic tape and angular tolerances, must be main-
tained over the entire test section! ( Img.5-6: to  Img.5-8:)
The max. gap without cover strip is 0.2 mm + 0.1 / -0mm. When using cover strip, the gap is reduced by the
thickness of cover strip including its cover strip. Sensor must not touch the magnetic strip.

5.6 Electrical connection
ATTENTION!
These magnetic sensors have been prepared for connection to DRO5. No modification of the
sensor connection (e.g. cable modification) is permitted.
Check all lines and connections before switching on the equipment.
5.6.1 Interference and distortion
All connections are protected against the effects of interference. The location should be selected to ensure
that no capacitive or inductive interferences can affect the sensor or the connection lines! Suitable wiring
layout and choice of cable an minimise the effects of interference (eg. interference caused by SMPS,
motors, cyclic controls and conductors).
5.6.2 Necessary measures:
The sensor should be positioned well away from cables with interference; if necessary a protective
screen or metal housing must be provided. The running of wiring parallel to the mains supply should be
avoided.
Contactor coils must be wired with spark suppression.
5.7 Maintenance
We recommend cleaning the magnetic strip's surface from time to time with a soft rag. This avoids dirt(dust,
chips, humidity ... ) sticking to the strip.
5.8 Trouble shooting
Below are some typical errors which may occur during installation and operation:
Magnetic strip incorrectly mounted (active surface must be mounted towards the sensor).  "Installa-
tion magnetic strip“ on page 23
To protect the magnetic tape the supplied cover tape was not used. Must always be non-magnetic.
Sensor incorrectly connected. Check connection
Tolerance for the gap between magnetic sensor and magnetic strip not observed over the total
traveldistance ( Img.5-6:).
Cable squeezed / interrupted / cut by sharp edges.
Sensor's active side not mounted towards the magnetic strip (  Img.5-8: and  Img.5-8:) .
Sensor has not been aligned according to  Img.5-5: and  Img.5-7:
