Other than adopting good technical construction methods, the information should be read carefully and
strictly applied. Inobservance of this information could cause risks for the health and safety of people and
economical damage. This information, provided by the Manufacturer in the original language(Italian) is also
available in other languages to satisfy legislative and/or commercial needs. This manual must be kept in good
conditions by a responsible person in an ideal place so that it is always available for consultation. In case this
manual is lost or deteriorates, a replacement should be requested directly from the manufacturer quoting the
manual’s code. This manual reflects the state of skill of the instrument at the time of input on the market:
however the manufacturer reserves the right to make changes, add or improve the manual without giving any
reason to hold the present manual inadequate.

The instrument does not needs a particular maintenance except cleaning to do only with a soft cloth dampen
with ethylic alcohol or water. Do not use hydrocarbon solvents (petrol, diluents, etc.): the using of these
products could affect the proper functioning of the instrument.
Reparations should be done only and exclusively at the FIAMA technical assistance centre.
Calibrations and tests
It is advisable to verify the transducer calibration periodically, once every working year.
Assistance request procedure
For any kind of technical assistance request, contact the sales department of the Manufacturer directly
indicating the information given on the identification plate, the number of hours used and the type of defect.
Manufacturer’s responsibility
The manufacturer declines any responsibility in case of :
• Using the instrument contrary to the national safety and accident-prevention laws.
• Wrong installation, inobservance or wrong procedures of the instructions provided in the present manual.
• Defective electrical power supply.
• Modifications or tampering.
• Operations carried out by untrained or unqualified staff.
The safety of the instrument also depends on the strict observance of the procedures indicated in the
manual: always operate the instrument in its functioning capacity and carry out a careful routine maintenance.
• All phases of inspection and maintenance should be done by qualified staff.
• The configurations provided in the manual are the only ones permitted.
• Do not try to use it anyway contrary to the indications provided.
• The instructions in this manual do not substitute but accomplish the obligations of the current legislation
regarding the safety laws.

Installation
Before installing the instrument, read the following warnings:
a) Connect the instrument strictly following the instructions of the manual.
b) It is the responsibility of the user to check, before using, the correct settings of the parameters of the
instrument to avoid damage to persons or things.
c) The instrument CANNOT function in a dangerous environment (inflammable or explosive).
Description
MAT2 is an absolute position transducer for linear measures without contact with a measure range up to 40
meters: it has to be combined with the absolute magnetic band PA50/10.
Running on the band, the sensor produces a signal which, properly amplified and worked out, is changed into
an absolute position signal.
Transducer MAT2 integrates in the same device a sensor sensible to magnetic fields, an electronic signals
conversion circuit and an output stage. The most importan feature is that this sensor always keeps the quota,
it means that is possible to move the sensor also without power supply and without loosing the quota. There
are available two inputs to define the zero-setting and the direction.
The data exchanging is made through protocol SSI with format Gray or Binary.
Magnetic Band PA50/10: the band consists of a plastic-ferrite strip carried by a stainless steel band with two
magnetic traces, one with alternate poles of 5 mm pitch, the other with an univocal binary.
This system is suitable for a large number of applications within industry: guides and linear transmission
members, pneumatic and oil-pressure cylin-ders, handling systems, automatic shearers, etc.: in any
situations where is necessary an absolute, accurate and repeatable measure without contact and wear-proof.
It can goes with display F1XSSI (reading range -99999, +999999) with interface SSI .

Transducer mounting
For the optimal operating of the system the magnetic sensor, is necessary to observe the quotas mounting
on the following draws, pay attention that the distance between the sensor and the magnetic band doesn’ t
exceed 0,8 mm.
Alignement tolerance magnetic band – transducer:
A color led indicator shows the following state:
1) green: transducer power on ok,
2) red: error condition.

Magnetic band
The band consists of a magnetized plastic ferrite strip with alternate magnetic poles, carried by a
ferromagnetic steel strip. Mechanical protection of the plastic ferrite strip is supplied by a non magnetic steel
strip with tickness 0,2mm.
The magnetic band is assembled by sticking it with a biadhesive tape. The surface has to be smooth, clean
and dry: is advisable to clean it with a degreasing product (isopropyl alcohol, ethyl alcohol, solvents, etc). The
magnetic band has to be sticked holding the plastic ferrite side in the direction of the sensor, which means
the steel side leaned on the stand surface. Fixed the magnetic band, to keep off damages due to abrasions
or grazes of the plasic ferrite strip, is advisable the appliance (always biadhesive) of the non magnetic
protection streep.
The optimal ambient temperature for stick the biadhesive tape is over 10°C. The maximum adherence of the
tape works out after 48 hours (about) of the application and is kept between –10 and 80°C.

Output signals
The transducer must be connected to an instrument which has an SSI 24 bit interface with Gray or Binary
coding (according to the chosen transducer version) with negative numbers represented in both cases in
two’s complement. The following schematic shows the clock and data signals:
The data is read from the MSB to the LSB.
Once the reading cycle has been completed, it is necessary to wait at least tm (15µs) before beginning a new
reading.
Admissible clock frequencies range from 32kHz to 1.5MHz but the actual maximum value depends upon also
the length of the connecting cable. In any case it is recommended to use a shielded twisted pair cable for the
clock and data signals.
In an environment which has noise, it can be useful to implement a verification on transmission errors by
executing a multiple reading cycle, i.e. after the first reading, initiate a second reading before tm has passed to
verify that the value has not changed meaning that both readings are the same. If in one of the two cycles the
value is corrupted by noise, the two values will be different and the reading must be repeated.
The data is a 24 (or 25 bit) right aligned, Binary (or Gray) coded.
Zero point setting
After the transducer has been positioned on the magnetic band, it is necessary to set the value to zero
otherwise the minimum value can be any value within the admissible range.
With the transducer fixed in position and correctly positioned on the magnetic band, by connecting the ZR
input to the positive wire, zero is assigned to the position in which the transducer is currently located. The
zero point that has been set will remain memorized by the system even after the instrument has been turned
off and will remain unvaried until a new point is set. The ZR input must return open (or closed towards GND)
after zeroing the value.
Note: the zeroing procedure must be repeated in case of substitution of the transducer or of the magnetic
band.
Setting the counting direction
Starting from the zero point, the data from the transducer will increase towards the left and decrease towards
the right (refer to the image on page 1). To change the counting direction connect the DIR input to the
positive wire.
