Prosonic S FMU90 - flow measurement - HART Safety Instructions
5
1SafetyInstructions
1.1 Designated use
The Prosonic S FMU90 is a transmitter for the ultrasonic sensors FDU91, FDU91F, FDU92, FDU93,
FDU95 and FDU96. The sensors of the former class FDU8x can be connected as well.
The transmitter version for level measurements (product structure according to section 2.3:
FMU90 - *1**********) can be applied for different measuring tasks, e.g.:
• level measurement in tanks and silos
• conveyor belt measurement
• level limit detection
• (alternating) pump control
• screen and rake control
The version for level and flow measurements (product structure according to section 2.3:
FMU90 - *2**********) is usable for further measuring tasks, e.g.:
• flow measurement at open flumes and weirs
• (non-resettable) totalizers and (resettable) counters
• control of samplers by time or counting pulses
• backwater and dirt detection in flumes
• simultaneous measurement of level and flow in a stormwater overflow basin with only one sensor
1.2 Installation, commissioning, operation
The Prosonic S FMU90 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 Hazardous area
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 supplementary documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local standards and 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. (Certificate is pending.)
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 (s. chapter
"Accessories").
Overvoltage protection
In order to protect the Prosonic against overvoltages (especially if mounted outdoors), connection
of an overvoltage protection is recommended (s. chapter "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" - 2" pipes (s. chapter
"Accessories").

3.3 Mounting the DIN-rail housing
3.3.1 Dimensions of the DIN-rail housing
The dimensions of the DIN-rail housing depend on the instrument version. The version determines,
which terminal areas the Prosonic S contains. The dimensions are influenced by the following
features of the product structure (see chapter 2.3):
• 60: Level Input
• 70: Switch Output
• 80: Output
In order to determine the dimensions of a specific version, perform the following steps (see the
example on page 15):
1. Using the product structure, determine the options of the features 60, 70 and 80 of the
instrument version in question.
2. Using the following table, determine how many optional terminal areas this instrument version
contains.
3. The appropriate dimensions are given in the following diagram:

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. 1 cm should be kept
between the instruments.
• 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.

3.4 Mounting the remote display and operating module
3.4.1 Scope of delivery
If the Prosonic S is ordered with the display for cabinet door mounting, the following is contained
in the scope of delivery:
• Display and operating module, 96x96 mm
• 4 retainers (with nuts and screws)
• Connection cable (3 m) for connection to the transmitter FMU90
(preassembled with suitable plugs; can not be extended).
3.4.2 Dimensions of the separate display and operating module

3.4.4 Adaption plate
If an opening of 115 mm x 115 mm and the remote display of the Prosonic FMU860/861/862 are
already present, you can use the adaption plate (Order Code: 52027441, s. chapter "Accessories").
It is inserted into the remote display of the FMU860/861/862.

(a): Remote display of the FMU90 with adaption plate; (b): Remote display of the FMU 860/861/862
3.5 Mounting of the sensors
Information on the mounting of the sensors can be found in the following documents:
• Technical Information TI 189F (for FDU8x)
• Technical Information TI 396F (for FDU9x)
These documents are supplied with the sensors.
"Caution!
Observe the mounting distances of the sensor as specified in chapter 15.1 ("Pre-programmed flow
curves")
3.6 Installation check
After installing the device, carry out the following checks::
• Is the device damaged (visual inspection)?
• Does the device correspond to the meausring point specifications such as process temperature,
process pressure, ambient temperature, measuring range etc?
• If available: Are the measuring point number and labelling correct?
• Is the instrument sufficiently protected against rainfall and direct sunlight?
• For the field housing: Are the cable glands tightened correctly?
• Is the instrument securely mounted to the DIN rail or the mounting help (visual inspection)?
• For the field housing: Are the screws of the terminal compartment cover securely tightened
(visual inspection)?

#Warning!
The instrument may only be installed if the supply voltage is switched off.
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.
L00-FMU90xxx-04-00-00-xx-002
For easier wiring, the lid can be completely removed by unplugging the display plug (1) and pulling
off the hinges (2):
L00-FMU90xxx-04-00-00-xx-009
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.

4.2 Terminal assignment
Pluggable spring-force terminals for connection of the cables are supplied in the terminal
compartment. Rigid conductors or flexible conductors with cable sleeve can directly be inserted and
are contacted automatically.
The terminal configuration depends on the instrument version ordered. There is a basic terminal
area, which is present in every instrument version. Additonal optional terminal areas are only
present if the respective option has been selected in the product structure.
L00-FMU90xxx-04-00-00-xx-001
Terminals of the Prosonic S; the terminals depicted in grey are not present in every instrument version.
A: Basic terminal area; B-D: Optional terminal areas (present if the respective option has been selected in the product
structure)
!Note!
The depticted switching states of the relays refer to the de-energized state.
Conductor cross section 0,2 mm2- 2,5 mm2
Cable and sleeve cross section 0,25 mm2- 2,5 mm2
