Basic safety instructions Micropilot FMR51, FMR52 HART

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 liquids, pastes and sludge. 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 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.

Micropilot FMR51, FMR52 HART Basic safety instructions
Endress+Hauser 7
Danger of burns due to heated surfaces!
‣For high process temperatures: Install protection against contact in order to prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
2.4 Operational safety
Risk of injury.
‣Operate the device in proper technical condition and fail-safe condition only.
‣The operator is responsible for interference-free operation of the device.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers.
‣If, despite this, modifications are 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 repair of an electrical device.
‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the hazardous
area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the intended
use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of these Instructions.
2.5 Product safety
This measuring 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.
NOTICE
Loss of degree of protection by opening of the device in humid environments
‣If the device is opened in a humid environment, the degree of protection indicated on the
nameplate is no longer valid. This may also impair the safe operation of the device.
2.5.1 CE mark
The measuring system meets the legal requirements of the applicable EC guidelines. These are
listed in the corresponding EC Declaration of Conformity together with the standards applied.
