Mounting

Additional conditions

• When mounting in the open, a weather protection cover (1) may be installed to protect the device against extreme weather conditions.

• In metallic vessels: Preferably do not mount the probe in the center of the vessel (2), as this would lead to increased interference echoes.

If a central mounting position can not be avoided, it is crucial to perform an interference echo suppression (mapping) after the commissioning of the device.

• Do not mount the probe in the filling curtain (3).

• Avoid buckling the rope probe during installation or operation (e. g. through product movement against silo wall) by selecting a suitable mounting location.

• Check the probe regularly for defects.

Note!

With suspended rope probes (probe end not fixed at the bottom) the distance between the probe rope and internal fittings in the tank must not fall below 300 mm (12 in) during the entire process. A sporadic contact between the probe weight and the cone of the vessel, however, does not influence the measurement as long as the dielectric constant of the medium is at least DC = 1.8.

Note!

When mounting the electronics housing into a recess (e. g. in a concrete ceiling), observe a minimum distance of 100 mm (4 in) between the cover of the terminal compartment/electronics compartment and the wall. Otherwise the connection compartment/electronics compartment is not accessible after installation.

6.1.3 Notes on the mechanical load of the probe

Tensile load limit of rope probes

Feature "Probe" Probe Tensile load limit [kN] Max. rupture load [kN]

Option 2, 3 Rope 4 mm (1/6 in) 316 12 20

Option M, Q Rope 6 mm (1/4 in) 316 30 42

Option N, S Rope 6 mm (1/4 in)

Option R, T Rope 8 mm (1/3 in)

Table 6.1

The ceiling of the silo must be designed to withstand this load.

PA > Steel

Tensile load

Bulk solids exert tensile forces on rope probes whose height increases with:

• the length of the probe, i. e. max. cover

• the bulk density of the product,

• the silo diameter and

• the diameter of the probe rope

12 20

30 42

Since the tensile forces are also heavily dependent on the viscosity of the product, a higher safety factor is necessary for highly viscous products and if there is a risk of cornice buildup. In critical cases it is better to use a 6 mm rope instead of a 4 mm one.

The same forces also act on the silo cover. On a fixed rope, the tensile forces are definitely greater, but this can not be calculated. Observe the tensile strength of the probes.

Options for reducing the tensile forces:

• Shorten the probe.

• If the maximum tensile load is exceeded, check whether it would be possible to use a noncontact ultrasonic or level-radar device.

The following diagrams show typical loads for frequently occurring bulk solids as reference values. The calculation is performed for the following conditions:

• Calculation according to DIN 1055, Part 6 for the cylindrical part of the silo.

• Suspended probe (probe end not fixed at the bottom)

• Free-flowing bulk solid, i. e. mass flow. A calculation for core flow is not possible. In the event of collapsing cornices, considerably higher loads can occur.

• The specification for tensile forces contains the safety factor 2 (in addition to the safety factors already taken into account by DIN 1055), which compensates for the normal fluctuation range in pourable bulk solids.

• 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.

• if otherwise the probe sporadically gets close to a concrete wall (minimum distance

0.5 m/20 in).

• The end of probe can be secured at its internal thread

• rope 4 mm (1/6 in), 316: M14

• rope 6 mm (1/4 in), 316: M20

• rope 6 mm (1/4 in), PA > steel: M14

• rope 8 mm (1/3 in), PA > steel: M20

• Preferably use the 6 mm (1/4 in) rope probe due to the higher tensile strength when fixing a rope probe.

• 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 the case of a grounded fixing the search for a positive end-of-probe signal must be activated. Otherwise an automatic probe length correction is impossible. Navigation: Expert  Sensor  EOP evaluation  EOP search mode Setting: Positive EOP option

• 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  1 cm/(1 m rope length) [0.12 in/(1 ft rope length)].

1. Using an Allen key, loosen the set screws at the end-of-probe weight. 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.

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.

7. Screw the set screws into place. Due to the clamping coating of the setscrews application of a screw locking fluid is not necessary.

Mounting rope probes

Warning!

Electrostatic discharges may damage the electronics.

• Earth the housing before lowering the rope into the vessel.

Figure 6.20

When lowering the rope probe into the vessel, observe the following:

• Uncoil rope and lower it slowly and carefully into the vessel.

• Do not kink the rope.

• Avoid any backlash, since this might damage the probe or the vessel fittings.

Note!

Mounting rope probes in a partially full silo

It is not always possible to empty a silo which is already in operation. If a minimum of 2/3 of the silo is empty, it is possible to install the probe into the partially filled silo. If possible, make a visual check after the installation to see that the rope has not tangled or is lying such that it can knot when the level falls. Before full accuracy is obtained the probe rope must hang fully extended.

8.2.3 Write protection via access code

Using the device-specific access code, the parameters for the measuring device configuration are write-protected and their values can no longer be changed via local operation.

Define access code via local display

1. Navigate to: Setup  Advanced setup  Administration  Define access code  Define access code

2. Define a max. 4-digit numeric code as an access code.

1. Navigate to: Setup  Advanced setup  Administration  Define access code

2. Define a max. 4-digit numeric code as an access code.

Write protection is active.

Parameters that can always be changed

The write protection does not include certain parameters that do not affect the measurement. Despite the defined access code, they can always be modified, even if the other parameters are locked.

If no key is pressed for 10 minutes in the navigation and editing mode, the device automatically locks the write-protected parameters. If the user goes from the navigation and editing mode back to the measured value display mode, the device automatically locks the write-protected parameters after 60 s.

Note!

• If write access is activated via access code, it can be also be deactivated only via the access code.

• In the "Description of Device Parameters" documents, each write-protected parameter is identified with the symbol.

8.2.4 Disabling write protection via access code

If the symbol appears on the local display in front of a parameter, the parameter is writeprotected by a device-specific access code and its value cannot be changed at the moment using the local display.

Disabling write protection

The locking of the write access via local operation can be disabled by entering the devicespecific access code.

1. After you press , the input prompt for the access code appears.

2. Enter the access code.

The symbol in front of the parameters disappears; all previously write-protected

parameters are now re-enabled.

13 Repairs

13.1 General information on repairs

13.1.1 Repair concept

The Pepperl+Fuchs repair concept assumes that the devices have a modular design and that repairs can be done by the Pepperl+Fuchs service or specially trained customers.

Spare parts are contained in suitable kits. They contain the related replacement instructions.

For more information on service and spare parts, contact the Service Department at Pepperl+Fuchs.

13.1.2 Repairs to Ex-approved devices

When carrying out repairs to Ex-approved devices, please note the following:

• Repairs to Ex-approved devices may only be carried out by trained personnel or by the Pepperl+Fuchs Service.

• Comply with the prevailing standards, national Ex-area regulations, safety instructions (SI) and certificates.

• Only use original spare parts from Pepperl+Fuchs.

• When ordering a spare part, please note the device designation on the nameplate. Only replace parts with identical parts.

• Carry out repairs according to the instructions. On completion of repairs, carry out the specified routine test on the device.

• Only Pepperl+Fuchs Service may convert a certified device into a different certified variant.

• Document all repair work and conversions.

13.1.3 Replacement of an electronics module

If an electronics module has been replaced, it is not necessary to perform a new basic setup as the calibration parameters are stored in the HistoROM which is located in the housing. However, after exchanging the main electronics module it may be necessary to record a new mapping (interference echo suppression).

13.1.4 Replacement of a device

After a complete device or electronic module has been replaced, the parameters can be downloaded into the instrument again in one of the following ways:

• Via the display module Condition: The configuration of the old device has been saved in the display module.

•Via PACTware Condition: The configuration of the old device has been saved to the computer via PACTware.

You can continue to measure without carrying out a new setup. Only a linearization and a tank map (interference echo suppression) have to be recorded again.
