1SafetyInstructions
1.1 Designated use
The Prosonic S FMU95 is a transmitter for up to 10 ultrasonic sensors FDU90, FDU91, FDU91F,
FDU92, FDU93, FDU95 and FDU96. The sensors of the class FDU8x can be connected as well.
Functions:
• display of up to 10 measuring values
• interference echo suppression for each connected sensor
• linearistaion for each sensor individually programmable
• configurable calculation of sums and average values
• measuring value transmission via PROFIBUS DP
1.2 Installation, commissioning, operation
The Prosonic S FMU95 is fail-safe and constructed to the state-of-the-art. It meets the appropriate
standards and EC directives. However, if you use it improperly or other than for its designated use,
it may pose application-specific hazards, e.g. product overflow due to incorrect installation or
configuration. Installation, electrical connection, start-up, operation and maintenance of the
measuring device must therefore be carried out exclusively by trained specialists authorised by the
system operator. Technical personnel must have read and understood these operating instructions
and must adhere to them. You may only undertake modifications or repair work to the device when
it is expressly permitted by the operating instructions.
1.3 Operational safety and process safety
Alternative monitoring measures must be taken to ensure operational safety and process safety
during configuration, testing and maintenance work on the device.
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this Additional documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.
The transmitter may only be installed in suitable areas. Sensors with a certificate for hazardous areas
may be connected to a transmitter without a certificate.
#Warning!
The sensors FDU83, FDU84, FDU85 and FDU86 with an ATEX, FM or CSA certificate are not
certified for connection to the FMU90 transmitter.
For installations in the USA:
Installation should be in accordance with the National Electrical Code NFPA 70 (NEC)
For installations in Canada:
Installation should be in accordance with the Canadian Electrical Code (CEC)

3.2.2 Installation conditions
Weather protection
In order to avoid excessive sunlight exposure, the instrument should be mounted in a position
which is protected against direct sunlight or a protection cover should be applied (ä88,
"Accessories").
Overvoltage protection
In order to protect the Prosonic against overvoltages (especially if mounted outdoors), connection
of an overvoltage protection is recommended (ä88, "Accessories").
Wall mounting
A mounting help for wall mounting is supplied. It also serves as drilling template. The mounting
help should be mounted on a flat surface and may not become distorted.
Pipe mounting
A mounting plate is available for mounting of the field housing to 1" to 2" pipes (ä88,
"Accessories").

3.3.2 Installation conditions
• The DIN-rail housing must be mounted outside hazardous areas in a cabinet.
• The housing is mounted on a DIN rail EN 60715 TH 35x7.5 or TH 37x15.
• Do not install the instrument in the vicinity of high-voltage lines, motor lines, contactors or
frequency converters. The installation regulations for high-voltage lines, motor lines, contactors
or frequency converters must be observed.
• To ensure easy mounting and opening of the housing, a distance of approx. 10 mm (0.39 in)
should be kept between the instruments.
• In order to avoid interference signals, the sensor cables must not be laid parallel to high voltage
or electric power lines.
• The cables may not be laid in the proximity to frequnecy converters.

3.4.4 Adaption plate
If an opening of 138 x 138 mm and the remote display of the Prosonic FMU860/861/862 are
already present, you can use the adaption plate (Order Code: 52027441, (ä88, "Accessories").
It is inserted into the remote display of the FMU860/861/862.
!Note!
The adapter plate is mounted directly in the housing of the old remote display of the FMU86x series.
The housing of the remote display of the FMU86x is the holder for the adapter plate and the new
remote display of the FMU90/FMU95 in the format 96 x 96 mm (3.78 x 3.78 in).

4.1 Terminal compartment
4.1.1 Terminal compartment of the field housing
The field housing has a separate terminal compartment. It can be opened after loosening the four
screws of the lid.

For easier wiring, the lid can be completely removed by unplugging the display plug (1) and loose-
ning the hinges (2):

4.1.2 Cable entries of the field housing
The following openings for cable entries are prestamped on the bottom of the housing :
• M20x1,5 (10 openings)
• M16x1,5 (5 openings)
• M25x1,5 (1 opening)
The required number and types of cable entries depend on the application at hand.
The prestamped openings can be removed by a suitable tool (e.g. knife or boring bit) or by punching
them out cautiously.

Open the catch of the cover (e.g. by a screwdriver).
Pull the cover out by approx. 20 mm (0.79 in) .
The cover can now be opened.
!Note!
• The cables can be inserted into the housing from above or from below.
• If the instruments are mounted next to each other and if the sensor cables run in parallel, the
synchronization terminals (39 and 40) must be interconnected (ä18 "Terminal assignment"
und ä24 "Synchronization line").

#Warning!
When using the public supply mains, an easily accesible power switch must be installed in the
proximity of the device. The power switch must be marked as a disconnector for the device (IEC/
EN 61010)
!Note!
• In order to avoid interference signals, the sensor cables should not be laid parallel to high voltage
or electric power lines.
• The cables may not be laid in the proximity to frequnecy converters.

#Warning!
On wiring, the supply voltage must be switched off.

4.3 Connection to a PROFIBIS DP network
!Note!
Information on the structure of a PROFIBUS DP network can be found in the Operating Instructions
BA 034S ("PROFIBUS PA/DP - Guidelines for planning and commissioning".
4.3.1 Cable specifications
For transmission rates up to 12 MBit/s cable type A according to EN 50170 can be used. The
specifications are summarized in the following table:
Pre-assembled cables are available from Endress+Hauser (ä88, "Accessories").
4.3.2 T-box
It is recommended to connect the Prosonic S to the bus by a T-box.
Suitable T-boxes are available from Endress+Hauser (ä88, "Accessories").
4.3.3 Spurs
Spurs are the connection cables from the bus to the instrument.
"Caution!
Obeserve the following:
• Total length of all spurs < 6.6 m (22 ft), (for a maximum baudrate of 1.5 MBit/s)
• For baud rates > 1.5 MBit/s no spurs should be used. A spur is the cable between the connector
and the bus driver in the field instrument. Plant experience has shown that much care should be
taken when planning the spurs. It can not be guaranteed that the sum of all spurs at 1.5 MBit/s
may be 6.6 m (22 ft). The actual arrangement of the field intruments has a great influence on this.
Therefore it is strictly recommended to use no spurs for transmission rates > 1.5 MBit/s.
• If usage of spurs can not be avoided, these may not have a bus bus termination.
