2.1. Version – MPI-R10-RF
The MPI-R10-RF is compatible with Elesa wireless network
that allows magnetic measuring system and indicators to
communicate via radio with a PLC.
Elesa wireless network is made by the following components:
- One control unit UC-RF
- Max 36 electronic position indicators or magnetic measuring
system, such as DD51-E-RF, DD52R-E-RF or MPI-R10-RF.
The control unit UC-RF is provided with a standard interface
for the most common industrial busses to be connected
to the PLC and allows the transmission of the information
between the PLC and the MPI-R10-RF magnetic measuring
system. The UC-RF exchanges information with the MPI-R10-
RF via radio frequency and allows the setting of the target
position and the control of the current position of each
indicator, directly from the PLC.

3.3. Magnetic band installation
To mount the magnetic band follow the instructions below:
- Clean the mounting surface carefully.
- Remove the protective film 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 film from the adhesive tape of the
cover strip.
- Stick the cover strip on the magnetic band. The cover
strip must be put on the magnetic band to protect it from
possible mechanical damages.
- In case of 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

8.5. Additional features
8.5.1. Reset
To reset the device to its factory setup:
- select the voice RESEt from the main menu (see chap. 8.3).
- select YES pressing the key
ORG
.
- press the key
SET
to confirm.
8.5.2. Calibration
The Calibration voice in the main menu activates the
CALIBRATION MODE and the display shows GO .
At this point, the user must slowly move the sensor in one
direction along the magnetic band.
After the GO , a progress bar is displayed that will grow as
long the sensor is moved. The procedure is completed when
the measurement position is shown again by the display.
This operation allows the sensor to be accurately bound to
the magnetic tape and has to be done every time after the
installation of the sensor.
8.5.3. Test LCD
The LcdtESt voice in the main menu allows to switch on all
the display segments.
8.5.4. Correction coefficients
To improve the correctness of the measurement, MPI-R10
allows to set two correction factors that take into account
the differencies between ideal and actual installation of the
magnetic band:
- LinCorr : is the ratio between the actual measurement
and the value measured by the device in linear
measurement.
- AngCorr : is the ratio between the actual measurement
and the value measured by the device in angular
measurement.
To calculate the correction factor, set it to 1 then read the
value measured (M) in a reference point (K). The correction
factor will be equal to K/M.
Verify that the measurement done in the reference point and/
or other known points is correct.
8.5.5. Revision
The release data of the device are shown, starting with the
r letter, as last voice in the main menu. These data can be
scrolled pressing the key
SET
.
Please note these values and communicate them to Elesa in
case of support needed.
9. Battery replacement
The internal lithium 1/2 AA - 3.6 V battery ensures over 3
years battery life (RF version - 2 years).
The symbol is shown on the display when the battery
replacement is required.
The replacement is made by simply removing the cover on
the back.
By replacing the battery in less than 5 seconds, all the
measurements and settings wil not be lost. If more time is
required and the display turns off, the settings of the device
have to be set or verified again.
