1SafetyInstructions
1.1 Designated use
The Prosonic S FMU90 is a transmitter for the ultrasonic sensors FDU90, FDU91, FDU91F, FDU92,
FDU93, FDU95 and FDU96. The sensors of the class FDU8x can be connected as well.
The transmitter version for level measurements (ä8, "Product structure":
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 (ä8, "Product structure":
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 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)

3.3 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 (ä8):
• 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 ä13):
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
