2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣Before beginning work, the specialist staff must have read and understood the
instructions in the Operating Instructions and supplementary documentation as well as
in the certificates (depending on the application)
‣Following instructions and basic conditions
The operating personnel must fulfill the following requirements:
‣Being instructed and authorized according to the requirements of the task by the
facility's owner-operator
‣Following the instructions in these Operating Instructions
2.2 Designated use
Application and measured materials
The measuring device described in these Operating Instructions is intended for the
continuous, contactless level measurement of liquids, pastes and sludge. The device can
also be freely mounted outside closed metal vessels because of its operating frequency of
about 26 GHz, a maximum radiated pulsed power of 5.7 mW and an average power output
of 0.015 mW (for the version with advanced dynamics: maximum pulse power: 23.3 mW;
average power: 0.076 mW). Operation is completely harmless to humans and animals.
Observing the limit values specified in the "Technical data" and listed in the Operating
Instructions and supplementary documentation, the measuring device may be used for the
following measurements only:
‣Measured process variables: level, distance, signal strength
‣Calculated process variables: Volume or mass in arbitrarily shaped vessels; flow
through measuring weirs or flumes (calculated from the level by the linearization
functionality)
To ensure that the measuring device remains in proper condition for the operation time:
‣Use the measuring device only for measured materials against which the process-
wetted materials are adequately resistant.
‣Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
‣For special measured materials and cleaning agents, Endress+Hauser is glad to provide
assistance in verifying the corrosion resistance of wetted materials, but does not accept
any warranty or liability.
Residual risk
The electronics housing and its built-in components such as display module, main
electronics module and I/O electronics module may heat to 80 °C (176 °F) during operation
through heat transfer from the process as well as power dissipation within the electronics.
During operation the sensor may assume a temperature near the temperature of the
measured material.
