Basic safety instructions Micropilot FMR67B HART
8 Endress+Hauser
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 primarily in bulk solids. Because of its operating frequency
of approx. 80 GHz, a maximum radiated peak power of 6.3 mW and an average output
power of 63 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 for the following measurements only:
‣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 against which the process-wetted materials
are adequately 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.
Danger of burns from contact with surfaces!
‣For elevated fluid temperatures, ensure protection against contact to prevent burns.

Micropilot FMR67B HART Basic safety instructions
Endress+Hauser 9
2.3 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.
2.4 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 the interference-free operation of the device.
Modifications to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers:
‣If modifications are nevertheless required, consult with the manufacturer.
Repair
To ensure continued operational safety and reliability:
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to the repair of an electrical device.
‣Use only original spare parts and accessories from the manufacturer.
Hazardous area
To eliminate danger to persons or the installation when the device is used in the
hazardous area (e.g. explosion protection, pressure vessel safety):
‣Check the nameplate to verify whether the ordered device can be put to its intended
use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation, which is an
integral part of this manual.
2.5 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.
2.6 Functional Safety SIL (optional)
The Functional Safety Manual must be strictly observed for devices that are used in
functional safety applications.
2.7 IT security
We only provide a warranty if the device is installed and used as described in the
Operating Instructions. The device is equipped with security mechanisms to protect it
against any inadvertent changes to the device settings. IT security measures in line with
operators' security standards and designed to provide additional protection for the device
and device data transfer must be implemented by the operators themselves.

Basic safety instructions Micropilot FMR67B HART
10 Endress+Hauser
2.8 Device-specific IT security
The device offers specific functions to support protective measures by the operator. These
functions can be configured by the user and guarantee greater in-operation safety if used
correctly. An overview of the most important functions is provided in the following section:
• Write protection via hardware write protection switch
• Access code (applies for operation via display, Bluetooth or FieldCare, DeviceCare, ASM,
PDM)

• Please contact the manufacturer's support department for applications with nozzles
that are higher than indicated in the table.
5.3.5 Antenna flush mount 80 mm (3 in) with alignment unit
UNI flanges with an integrated alignment unit are available for the antenna flush mount
80 mm (3 in). An inclination of the antenna axis of up to 15 ° in all directions can be set
with the help of the alignment unit. The alignment unit is used to optimally align the
measuring signal to the bulk solids.

In the case of longer nozzles, reduced measuring performance must be expected.
Please note the following:
• The end of the nozzle must be smooth and free from burrs.
• The edge of the nozzle should be rounded.
• Mapping must be performed.

5.3.6 Purge air connection
In applications with strong dust emissions, the integrated purge air connection can prevent
the antenna from becoming clogged. Pulse operation is recommended.

NOTICE
The housing cannot be unscrewed fully.
‣Loosen the external locking screw by a maximum of 1.5 turns. If the screw is
unscrewed too much or completely (beyond the screw anchor point), small parts
(counter disk) can become loose and fall out.
