The magnetic band M-BAND-10 is made of two separate parts: the
magnetic band and the cover strip. The magnetic band is made of
a magnetic tape, a carrier strip and an adhesive tape (Fig. 2). The
cover strip is made of a protection strip and an adhesive tape (Fig. 1).
3. Installation
3.1 Display and battery case installation
1) Make a drilling of 42
+0.2/+0.5
mm x 90
+0.2/+0.5
mm in the metal sheet
for the installation of the display.
2) Fix the display to the panel by using the specific mounting bracket
(the screw is included in the supply).
3) Make a drilling of diameter 34
+0.2/+0.5
mm in the metal sheet for the
installation of the battery case.
4) Fix the battery case to the panel by using the specific nut.
5) Fix the magnetic sensor by using M3 screws (not included in the
supply). Distance between sensor and magnetic tape to ensure a
correct reading of the displacement: max 2.5 mm.
The cable layout should be outlined to prevent damages due
to cable strain or contacts of the cable with other machine
components. It is recommended that the cable is installed sufficiently
far from magnetic / electromagnetic sources.
Battery type
Batteries are not supplied together with the MPI-15. The following
standard battery is recommended: 1 x C battery
Battery substitution
When the display shows the battery symbol, the battery should be
replaced as soon as possible. After the removal of the battery, the
display memory is buffered for approximately 60 seconds. Substitute
the battery within this time frame.
3.2 Magnetic band installation
The cover strip must be installed over the magnetic band to protect it
from possible mechanical damages.
1) Clean the mounting surface carefully.
2) Remove the protective foil from the adhesive tape of the magnetic
band.
3) Stick the magnetic band on the mounting surface.
4) Clean the surface of magnetic band carefully.
5) Remove the protective foil from the adhesive tape of the cover
strip.
6) Stick the cover strip on the magnetic band.
7) In the absence of a seat for the housing of M-BAND-10, secure
the ends of the cover strip to prevent unintentional peeling.
The mounting surface must be flat. Buckles or bumps will
lead to measuring inaccuracies.
To guarantee an optimal adhesion of the adhesive tapes, the
mounting surfaces must be perfectly cleaned, dry and smooth.
The following surface roughness is recommended: Ra <= 3,2 N8
(Rz <= 25). To maximize the adhesion install the strip applying
pressure. Gluing should preferably be carried out at temperatures
between 20 °C to 30 °C and in dry atmosphere.
Once the installation is completed, the calibration procedure must be
carried out as shown at Paragraph 7.
