Endress+Hauser 9
2 Basic safety instructions
2.1 Requirements for the personnel
The personnel must fulfill the following requirements for its tasks:
‣
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 starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the application).
‣
Follow instructions and comply with basic conditions.
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 mainly bulk solids. The device can also be freely
mounted outside closed metal vessels (e.g. above basins, open channels or open piles) because
of its operating frequency of about 26 GHz, a maximum radiated pulsed power of 23.3 mW
and an average power output of 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.
Danger of burns due to heated surfaces!
‣
For high process temperatures: Install protection against contact in order to prevent burns.
