3. Installation
3.1 Display installation
1. Drill the panel according to the template dimensions reported.
2. Remove all drilling burrs before fitting the MPI-R10.
3. Fit the lower part of the case into the housing.
4. Press onto the upper part until the case is completely snapped in.
3.2 Sensor installation
Fix the magnetic sensor by using M3 screws (not included in the supply).
During the installation, use a planar spacer (max 1 mm is suggested) to grant the
parallelism between the sensor and the magnetic band.
The maximum distance between the sensor and the magnetic band to ensure a
correct reading of the displacement is 1mm
3.3 Magnetic band installation
To mount the magnetic band follow the instructions below:
• Clean the mounting surface carefully.
• Remove the protective foil from the adhesive tape of the magnetic band.
• Stick the magnetic band on the mounting surface.
• Clean the surface of the magnetic band carefully.
• Remove the protective foil from the adhesive tape of the cover strip.
• Stick the cover strip on the magnetic band. The cover strip must be installed
over the magnetic band to protect it from possible mechanical damages.
• 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.
WARNING
Once the installation is completed, the calibration procedure must be carried out
as shown in cap. 8.5.2.

setting.
To program the targets:
- selet tArGEtS in the main menu (see cap 8.3)
- select PrOG_TG (see cap. 8.4)
- select the wanted memory location ( PtrG 01 to PtrG 32 )
- press the key
SET
to select.
Follow the instruction in cap. 8.1.1 to set the wanted value.
To load a target:
- selet tArGEtS in the main menu (see cap 8.3)
- select LOAd_TG (see cap. 8.4)
- select the wanted target value ( LtrG 01 to LtrG 32 ) using the keys
ABS-REL
and
ORG
- press the key
SET
to select
- the value of the selected target is shown
- press
SET
again to confirm or press
mm-inch
to go back to the target selection list.
If one target is selected, one of the symbols will appear on the top right
of the display, to suggest the direction of movement of the sensor to get to the
target position.
It is possible to set the FLIP_tG parameter (see cap. 8.2) to adapt the target
position indication to the actual sensor configuration.
It is possible to set the tolerance of the target as absolute difference from the set
value by means of the P_tOLL parameter (see cap. 8.2)
The target position indicators will work, depending from the FLIP_tG and P_tOLL
parameters, as in the following table:
FLIP FLIP
M < T - Toll T = set target
T - Toll <= M < T M = measured value
M = T Toll = tolerance (see P_toll)
T < M < = T + Toll
M > T + Toll
