Steps
• If there is a cover strip, this is to be removed
first.
• To determine the pole division either use
metal dust, a magnet magnifier or magnetic foil.
• If necessary, use a compass needle to deter-
mine the location of the poles on the magnetic
strip (fig. 8).
• Use a rule and a sharp knife to cut the
magnetic strip at a right angle. Then also cut the
carrier strip accordingly.
• Previous steps are to be repeated with the
other part of strip.
• Check polarity before joining the two parts.
Both ends must attract each other (if necessary,
use compass needle). In case both ends have
the same polarity, shorten one end by a half pole
division (fig. 9).
• Join the two ends closely together and add the
cover strip.
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.
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)
(see chapter 3.1)
• Use of foreign protective strip. Must always
be non-magnetic.
• Sensor not or incorrectly connected (pin con-
nection, see chapter 5).
• Tolerance for the gap between magnetic sen-
sor and magnetic strip not observed over the
total travel distance. Sensor touches strip (see
fig. 6)
• Cable squeezed / interrupted / cut by sharp
edges.
• Sensor’s active side not mounted towards the
magnetic strip (see fig. 6). The active side is
marked by the label "scale side".
• Sensor has not been aligned according to
chapter 3.2.
