Micropilot FMR67B PROFIBUS PA Requirements for personnel
Endress+Hauser 5
2 Requirements for 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.
‣Personnel must be authorized by the plant owner/operator.
‣Personnel must 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.
3 Intended use
Application and media
The measuring device described in these Operating Instructions is intended for continuous,
non-contact level measurement primarily in bulk solids. Due to its operating frequency of
approx. 80 GHz, a maximum radiated peak power of <1.5 mW and an average power output
of <70 µW, unrestricted use outside of closed, metallic vessels is also permitted (for example
over heaps). Operation does not pose any danger whatsoever to humans and animals.
If the limit values specified in the "Technical data" and the conditions listed in the instructions
and additional documentation are observed, the measuring device may be used only for the
following measurements:
‣Measured process variables: level, distance, signal strength
‣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 are
sufficiently resistant.
‣Observe the limit values in the "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-intended use.
Avoid mechanical damage:
‣Do not touch or clean device surfaces with pointed or hard objects.
Clarification of borderline cases:
‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in
verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability.
Residual risks
Due to heat transfer from the process as well as power loss in the electronics, the temperature
of the electronics housing and the assemblies it contains (e.g. display module, main
electronics module and I/O electronics module) may rise to 80 °C (176 °F). When in operation,
the sensor may reach a temperature close to the medium temperature.

Workplace safety Micropilot FMR67B PROFIBUS PA
6 Endress+Hauser
Danger of burns from contact with surfaces!
‣For elevated fluid temperatures, ensure protection against contact to prevent burns.
4 Workplace safety
When working on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
‣Switch off the supply voltage before connecting the device.
5 Operational safety
Risk of injury!
‣Operate the device only if it is in proper technical condition, free from errors and faults.
‣The operator is responsible for interference-free operation of the device.
Hazardous area
To eliminate the risk of danger to persons or the facility when the device is used in the
approval-related area (e.g. explosion protection, pressure equipment safety):
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
approval-related area.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of this manual.
6 Product safety
This device is designed in accordance with good engineering practice to meet state-of-the-art
safety requirements, has been tested, and left the factory in a condition in which it is safe to
operate.
It meets general safety standards and legal requirements. It also complies with the EC
directives listed in the device-specific EC Declaration of Conformity. Endress+Hauser confirms
this by affixing the CE mark to the device.
