2 Basic safety instructions
2.1 Requirements for 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.
‣
Personnel must be authorized by the plant owner/operator.
‣
Be familiar with federal/national regulations.
‣
Before starting work: personnel must read and understand the instructions in the
manual and supplementary documentation as well as the certificates (depending on
the application).
‣
Personnel must follow instructions and comply with general policies.
The operating personnel must fulfill the following requirements:
‣
Personnel are instructed and authorized according to the requirements of the task by
the facility's owner-operator.
‣
Personnel follow the instructions in this manual.
2.2 Intended use
Application and media
The measuring device described in these Operating Instructions is intended for continuous,
non-contact level measurement of solids. Because of its operating frequency of approx.
26 GHz, a maximum radiated pulsed power of 5.7 mW and an average power output of
0.015 mW, use outside of closed, metallic vessels is also permitted. If operated outside of
closed vessels, the device must be mounted in accordance with the instructions in the
"Installation" section. The operation of the devices does not present any health risk.
If the limit values specified in the "Technical data" and the conditions listed in the manual
and additional documentation are observed, the measuring device may be used for the
following measurements only:
‣
Measured process variables: distance
‣
Calculable process variables: volume or mass in any shape of vessel
To ensure that the measuring device remains in proper condition for the operation time:
‣
Use the measuring device only for media to which the process-wetted materials have
an adequate level of resistance.
‣
Observe the limit values (see "Technical data").
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Clarification of borderline cases:
‣
With regard to special media and media used for cleaning, please contact the
manufacturer. Hauser will be happy to assist in clarifying the corrosion-
resistant properties of wetted materials but does not accept any warranty or liability.
Residual risks
Due to heat transfer from the process as well as power dissipation within the electronics,
the temperature of the electronics housing and the assemblies contained therein may rise
to 80 °C (176 °F) during operation. When in operation, the sensor can reach a temperature
close to the medium temperature.
Danger of burns from contact with surfaces!
‣
In the event of elevated medium temperatures, ensure protection against contact to
prevent burns.
