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 only for level and
interface measurement of liquids. Depending on the version ordered the device can also
measure potentially explosive, flammable, poisonous and oxidizing materials.
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 variable: Level and/or interface
‣Calculated process variable: Volume oder mass in arbitrarily shaped vessels (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.
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.
With divisible probe rods, medium may penetrate into the joints between the indivual parts of
the rod. This medium may escape when loosening the joints. In the case of dangerous (e.g.
aggressive or toxic) media this may cause injuries.
‣When loosening the joints between the individual parts of the probe rod: Wear appropriate
protective equipment according to the medium.
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.

Mounting distances
• Distance (A) between wall and rod or rope probe:
– for smooth metallic walls: > 50 mm (2 in)
– for plastic walls: > 300 mm (12 in) to metallic parts outside the vessel
– for concrete walls: > 500 mm (20 in), otherwise the available measuring range may be
reduced.
• Distance (B) between rod or rope probe and internal fittings in the vessel: > 300 mm (12 in)
• When using more than one Levelflex:
Minimum distance between the sensor axes: 100 mm (3.94 in)
• Distance (C) from end of probe to bottom of the vessel:
– Rope probe: > 150 mm (6 in)
– Rod probe: > 10 mm (0.4 in)
– Coax probe: > 10 mm (0.4 in)
For coax probes the distance to the wall and to internal fittings is arbitrary.

2 Mounting kit isolated
• The end of the probe needs to be secured under the following conditions:
if otherwise the probe sporadically comes into contact with the wall of the vessel, the outlet
cone, internal fittings or other parts of the installation.
• The end of probe can be secured at its internal thread
rope 4 mm (1/6"), 316: M 14
• The fixing must be either reliably grounded or reliably insulated. If it is not possible to
mount the probe weight with a reliably insulated connection, it can be secured using an
isolated eyelet, which is available as an accessory.
• In order to prevent an extremely high tensile load (e.g. due to thermal expansion) and the
risk of rope crack, the rope has to be slack. Make the rope longer than the required
measuring range such that there is a sag in the middle of the rope that is ≥ 1cm/(1 m rope
length) [0.12 inch/(1 ft rope length)].

Securing rod probes
• For WHG approvals: For probe lengths ≥ 3 m (10 ft) a support is required.
• In general, rod probes must be supported if there is a horizontal flow (e.g. from an agitator)
or in the case of strong vibrations.
• Rod probes may only be supported at the end of the probe.

6.2 Mounting the device
6.2.1 Required mounting tools
• For mounting thread 3/4": Hexagonal wrench 36 mm
• For mounting thread 1-1/2": Hexagonal wrench 55 mm
• To shorten rod or coax probes: Saw
• To shorten rope probes:
– Allen key AF 3 mm (for 4mm ropes) or AF 4 mm (for 6 mm ropes)
– Saw or bolt cutter
• For flanges and other process connections: appropriate mounting tools
• To turn the housing: Hexagonal wrench 8 mm
6.2.2 Shortening the probe
Shortening rod probes
Rod probes must be shortened if the distance to the container floor or outlet cone is less than
10 mm (0.4 in). The rods of a rod probe are shortened by sawing at the bottom end.
Rod probes of FMP52 can not be shortened as they are coated.
Shortening rope probes
Rope probes must be shortened if the distance to the container floor or outlet cone is less than
150 mm (6 in).
Rope probes of FMP52 can not be shortened as they are coated.

1. Using an Allen key, loosen the set screws at the end-of-probe weight or the clamping
sleeve of the centering disk. Note: The set screws have got a clamping coating in order
to prevent accidental loosening. Thus an increased torque might be necessary to loosen
them.
2. Remove released rope from the weight or sleeve.
3. Measure off new rope length.
4. Wrap adhesive tape around the rope at the point to be shortened to prevent it from
fanning out.
5. Saw off the rope at a right angle or cut it off with a bolt cutter.
6. Insert the rope completely into the weight or sleeve.
7. Screw the set screws into place. Due to the clamping coating of the setscrews application
of a screw locking fluid is not necessary.
