3 Basic safety instructions

3.1 Requirements for personnel

The personnel must fulfill the following requirements for its tasks:

‣Trained, qualified specialists must have a relevant qualification for the specific function

and task

‣Are authorized by the plant owner/operator

‣Are familiar with federal/national regulations

‣Must have read and understood the instructions in the manual and supplementary

documentation

‣Follow instructions and comply with conditions

3.2 Intended use

Application and media

The measuring device described in this manual is intended only for the level and interface

measurement of liquids. Depending on the version ordered, the measuring device can also

measure potentially explosive, flammable, poisonous and oxidizing media.

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: level and/or interface height

‣Calculable process variables: volume or mass in any shape of vessel (calculated from the

level by the linearization functionality)

Levelflex FMP51 Modbus Basic safety instructions

Endress+Hauser 5

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 in the "Technical data".

Incorrect use

The manufacturer is not liable for damage caused by improper or non-intended use.

Verification for 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 contained therein (e.g. display module, main

electronics module and I/O electronics module) may rise up 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!

‣In the event of high medium temperatures, ensure protection against contact to prevent

burns.

3.3 Workplace safety

When working on and with the device:

‣Wear the required personal protective equipment according to federal/national

regulations.

With divisible probe rods, medium may penetrate the joints between the individual parts of

the rod. This medium may escape when the joints are loosened. This can cause injuries in the

case of dangerous (e.g., aggressive or toxic) media.

‣When loosening the joints between the individual parts of the probe rod, wear appropriate

protective equipment according to the medium.

3.4 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.

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.

3.5 Product safety

The measuring system meets the legal requirements of the applicable EU directives. These are

listed in the corresponding EU Declaration of Conformity together with the standards applied.

The manufacturer confirms successful testing of the device by affixing to it the CE mark.

3.5.2 EAC conformity

The measuring system meets the legal requirements of the applicable EAC guidelines. These

are listed in the corresponding EAC Declaration of Conformity along with the standards

applied.

The manufacturer confirms successful testing of the device by affixing to it the EAC mark.

(www.endress.com/deviceviewer)

 All of the information on the measuring device and on the scope of the technical

documentation pertaining to the device is displayed.

‣Enter the serial number from the nameplate in the Endress+Hauser Operations app or scan

the 2-D matrix code on the nameplate with the camera

 All of the information on the measuring device and on the scope of the technical

documentation pertaining to the device is displayed.

4.3 Storage and transport

4.3.1 Storage temperature

• Permitted storage temperature: –40 to +80 °C (–40 to +176 °F)

• Use original packaging.

• Option for FMP51 and FMP54: –50 to +80 °C (–58 to +176 °F)

This range applies if the option JN "Transmitter ambient temperature" –50 °C (–58 °F) was

selected in order code 580 "Test, Certificate". If the temperature is permanently below

–40 °C (–40 °F), higher failure rates can be expected.

4.3.2 Transporting the product to the measuring point

LWARNING

Housing or rod may become damaged or pull off.

Risk of injury!

‣Transport the measuring device to the measuring point in its original packaging or by the

process connection.

‣Always secure lifting equipment (slings, eyes, etc.) at the process connection and never lift

the device by the electronic housing or probe. Pay attention to the center of gravity of the

device so that it does not tilt or slip unintentionally.

‣Follow the safety instructions and transport conditions for devices weighing more than 18

kg (39.6 lbs) (IEC 61010).
