2 Basic safety instructions

2.1 Requirements for the 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

‣Are authorized by the plant owner/operator

‣Are familiar with federal/national regulations

‣Before beginning work, the specialist staff must have read and understood the

instructions in the Operating Instructions and supplementary documentation as well as

in the certificates (depending on the application)

‣Following instructions and basic conditions

The operating personnel must fulfill the following requirements:

‣Being instructed and authorized according to the requirements of the task by the

facility's owner-operator

‣Following the instructions in these Operating Instructions

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 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.

Basic safety instructions Micropilot FMR51, FMR52 FOUNDATION Fieldbus

8 Endress+Hauser

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 they are 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.
