Basic safety instructions
Requirements for the personnel
The personnel must fulfill the following requirements to carry out the
necessary tasks:
- Are trained, qualified to perform specific functions and tasks.
- Are authorized by the plant owner or operator to perform specific tasks.
- Are familiar with federal or national regulations.
- Have read and understood the instructions in the manual and supplementary documentation.
- They follow instructions and comply with conditions.
Workplace safety
For work on and with the device:
- Wear the required protective equipment according to federal or national regulations.
Operational safety
When performing configuration, testing, and maintenance work on the device,
alternative supervisory measures must be taken to guarantee the operational
safety and process safety.
Ex-area
When using the measuring system in Ex-areas, the appropriate national
standards and regulations must be observed. Separate Ex-documentation, which
constitutes an integral part of this documentation, is supplied with the
device. The installation procedures, connection data and safety instructions
it contains must be observed.
- Make sure that the technical staff has adequate training.
- The special measuring and safety-related requirements for the measuring points must be observed.
Product safety
This measuring device is designed following good engineering practice to meet
state-of-theart 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 is compliant 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.
Incoming acceptance and product identification
Incoming acceptance
Check whether the packaging or content is damaged. Check that the goods
delivered are complete and compare the scope of delivery with the information
in your order.
Product identification
Check nameplate data.
See Operating Instructions→ 2
Storage and transport
For storage and transportation, pack the device to protect it against impact.
The original packing offers the best protection for this. The permitted
storage temperature is –50 to +85 °C (–58 to +185 °F).

General notes and precautions
Filling the silo.
- The filling stream must not be directed onto the probe.
NOTICE
Angle of material flow.
- Take care to the expected angle of the material flow and the outlet funnel when determining the mounting location or probe rod length.
NOTICE
Distance between probes.
- The minimum distance of 500 mm (19.7 in) between the probes must be observed.
NOTICE
Threaded coupling for mounting.
- The threaded coupling must be as short as possible. Condensation or product residue can occur in a long threaded coupling and interfere with the correct operation of the probe.
NOTICE
Heat insulation
- Insulate the external silo wall to avoid exceeding the permitted temperature of the Solicap M housing.
- Insulate the silo wall to prevent the condensation and reduce buildup in the threaded coupling area.
α Angle of the slope
- FTI55
- FTI56
- Distance from the loading point
- Heat insulation
Mounting the sensor
The Solicap M FTI55 can be installed:
- from above
- from the side
NOTICE
Mouting the probe rod in the loading curtain area can cause a incorrect device
operation!
- Mount the probe away from the loading curtain.
NOTICE
The probe rod cannot touch the metal container wall!
- Make sure that the probe rod is insulated from the metal container wall.
1 Mounting examples. Unit of measurement mm (in)
- For maximum level limit detection
- For minimum point level detection
- The protective cover protects the probe rod from collapsing mounds or mechanical strain at the outflow.
- In the event of light buildup on the silo wall, the threaded coupling is welded internally. The probe tip points slightly downwards so that bulk solids slide off more easily.
Installing the probe in a silo with concrete walls
The grounded steel plate forms the counter electrode. The heat insulation
prevents condensation and therefore buildup on the steel plate.The steel plate
can be a round or square shape.
- Sheet metal plate with threaded socket
- Heat insulation
Installing the probe in a silo with plastic walls
If the probe is instaled in the silo with plasic walls, a sheet metal plate
must be attached to the exterior of the silo as a couters elctrode. The plate
can be in square or round shape.
The dimentions of the plate are:
- approximately square of 500 mm (19.7 in) each side or round ⌀500 mm (19.7 in) for thin wall with low dielectric constant
- approximately square of 700 mm (27.6 in) each side or round ⌀700 mm (27.6 in) for thick wall with high dielectric constant
- Electrical HF field
- Sheet metal plate
- Ground connection
Installing the probe in an event of buildup
The buildup on the probe’s rod can cause distortions in the measurement
result. Set the function of an active buildup compensation. Cleaning of the
probe’s rod is not necessary.
Probe length and minimum coverage
For probe length tolerances, see TI01556F.
- To ensure problem-free operation, it is important that the difference in capacitance between the covered and uncovered parts of the probe is at least 5 pF.
- If you do not know the dielectric constant of the material, contact the E+H service.
Pay attention to the dependency between the relative dielectric constant εr and the minimum amount the probe rod that needs to be covered.
Minimum lenght of the probe rod (Lmin) that needs to be covered
- 25 mm (0.98 in) for electrically conductive product
- 100 mm (3.94 in) for nonconductive product εr > 10 nF/m
- 200 mm (7.87 in) for nonconductive product εr > 5 to 10 nF/m
- 500 mm (19.7 in) for nonconductive product εr > 2 to 5 nF/m
Installation instructions
NOTICE
Do not damage the probe insulation during installation!
- Check the rod insulation.
NOTICE
Do not screw the probe using the probe housing!
- Use an open-end wrench to screw the probe
Aligning the housing
The housing can be rotated 270 ° to align the cable entry. To prevent moisture
penetration, route the connecting cable downwards in front of the cable gland
and secure it with a cable tie. This is particularly recommended for outdoor
mounting.
-
Loosen the clamping screw.
-
Align the housing into the needed position.
-
Tighten the clamping screw with torque < 1 Nm (0.74 lbf ft).
Electrical connection
Before connecting the power supply, note the following:
the supply voltage must match the data specified on the nameplate
- switch off the supply voltage before connecting the device
- connect the potential equalization to the ground terminal on the sensor
When using the probe in hazardous areas, the relevant national standards and the information in the safety instructions (XA) must be observed. Use the specified cable gland only
Connecting requirements
Potential equalization
DANGER
Risk of explosion!
- Connect the cable screen on the sensor side only if installing the probe in Ex areas!
Cable specification
Connect the electronic inserts by using commercially available instrument
cables. If a potential equalization is present, and the shielded instrument
cables are used, connect the shielding on both sides to optimize the shielding
effect.
