3.9 Installation instructions

3.9.1 Installation

The Solicap M FTI55 (rod probe) can be installed from above and from the side. The Solicap M FTI56 (rope probe) can be installed vertically from above.

Note! The probe may not come into contact with the container wall! Do not install probes in the area of the filling curtain!

3.9.2 General notes

Filling the silo

The filling stream should not be directed onto the probe.

Angle of material flow

Note the expected angle of the material flow or of the outlet funnel when determining the mounting location or probe length.

Distance between probes

When installing several probes in a silo, a minimum distance of

0.5 m between the probes must be observed.

Threaded coupling for mounting

When installing the Solicap M FTI55, FTI56, the threaded coupling should be as short as possible. Condensation or product residue may occur in a long threaded coupling and interfere with the correct operation of the probe.

Heat insulation

In the event of high temperatures in the silo: Insulate the external silo wall to avoid exceeding the permitted temperature of the Solicap M housing. Heat insulation also prevents condensation from forming near the threaded boss in the silo. This reduces buildup and the risk of error switching.

3.9.3 Preparing to install rod probes FTI55

Correct installation

a. For maximum level limit detection, a short threaded coupling is used.

b. For minimum point level detection, a short threaded coupling is used.

The probe tip points slightly downwards so that bulk solids slide off more easily. The protective cover protects the probe rod from collapsing mounds or mechanical strain at the outflow.

c. 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.

Incorrect installation

d. The threaded coupling is too long. This may cause material to settle inside and result in error

switching.

e. Horizontal mounting means a risk of error switching in the event of heavy buildup on the silo

wall. In this case, the Solicap M FTI55 (rod probe) with inactive length is recommended.

f. In areas where product buildup occurs, the device cannot detect if the silo is "empty".

In this case, the FTI56 (rope probe) should be installed from above.

Probe length and minimum coverage

Note!

• When selecting the probe length, pay attention to the dependency between the relative dielectric constant 

and the minimum amount the probe rod needs to be covered (see Table).

• For probe length tolerances see Page 19 ff.

• 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 us for advice.

In this example, the grounded steel plate forms the counter electrode. Heat insulation prevents condensation and therefore buildup on the steel plate.

TI418Fen09

In a silo with concrete walls

When installing in a silo made of plastic, a sheet metal plate must be attached to the exterior of the silo as a counter electrode. This plate can be either square or round.

– Dimensions in the case of a thin silo wall

with a low dielectric constant: approx. 0.5 m along each side or ø0.5 m;

– Dimensions in the case of a thicker silo wall

or wall with a higher dielectric constant: approx. 0.7 m along each side or ø0.7 m.

3.9.4 Preparing to install rope probes FTI56

Correct installation

a. Solicap M FTI55, FTI56 with inactive length in the event of condensation and material

buildup on the silo roof.

b. At the correct distance from the silo wall, the material inlet and the material outlet.

Close to the wall, for reliable switching in the case of a low dielectric constant (not for pneumatic filling). For pneumatic filling, the distance from the probe to the wall should not be too short, as the probe may swing.

Incorrect installation

c. If too close to the material inlet, inflowing bulk solids may damage the sensor.

If close to the center of the material outflow, high tensile forces at this point may cause the probe to break off or subject the silo roof to excessive strain.

d. The threaded coupling is too long. This may cause condensation and dust to settle inside which

may result in error switching.

e. If too close to the silo wall, the probe may swing slightly against the wall or come in contact

with buildup.This can result in error switching.

Silo roof

Ensure that the silo roof is of a sufficiently stable construction. High tensile forces may occur when material is being extracted, particularly in the case of heavy and powdery bulk solids which have a tendency to form buildup.

Coarse-grained bulk solids

In silos with extremely coarse-grained or extremely abrasive bulk solids, the use of a Solicap M FTI55 or FTI56 is recommended only for maximum detection.

Distance between the rope probes

To rule out mutual probe interference, you must maintain a minimum distance of 0.5 m between the rope probes. This also applies if you are installing several Solicap M units in adjacent silos with nonconductive walls.

In the event of condensation:

Use the Solicap M with inactive length. The inactive length (A) prevents moisture and buildup forming between the active part of the probe and the silo roof.

Or: To reduce the effects of condensation (B) and buildup, the threaded coupling (length: max. 25 mm) must project into the silo. Heat insulation reduces condensation and therefore buildup on the steel plate.

Installation in plastic tanks

If buildup on the probe rod can be expected when operating the measuring system, the active buildup compensation function prevents the measurement result from becoming distorted. No cleaning work has to be performed on the probe rod.

BA300Fxx020

When installing in a silo made of plastic, a counter electrode must be mounted on the silo exterior at the same height as the tensioning weight. The length of the edge of the counter electrode should be approximately the same length as the distance between the tensioning weight and the silo wall.

(covered length): For nonconductive bulk solids with a low dielectric constant, the rope probe must be approx. 5 % (but no less than 250 mm) longer than the distance between the tank roof and the required level limit.

• Release the set screws at the tensioning weight and remove the rope.

• Shorten the probe rope to the desired length.

• In the case of insulated ropes with a diameter of 8 mm, the end of the rope has to be stripped so that it can be guided into the tensioning weight.

• Slide the rope back in, as far as the end of the bore, and secure it using the set screws.

A recalibration must be performed before commissioning  ä 53

Note! The maximum connection length between the probe and the separate housing is 6 m. When ordering a device with a separate housing, the desired length must be specified.

If the connecting cable is to be shortened or guided through a wall, it must be disconnected at the process connection. To do so, proceed as follows:

• Unscrew the pressing screw (1) using a 22mm open-end wrench. If necessary, hold the process connection. In doing so, ensure that neither the connecting cable nor the probe is turned in the process.

• Pull the insert seal (2) out of the cable gland (3).

• Using a 22mm open-end wrench, disconnect the cable gland (3) from the adapter disk. If necessary, hold it against the adapter disk (6) using a 34mm open-end wrench.

• Disconnect the adapter disk (6) from the adapter bushing (18).

• Remove the snap ring with a snap ring pliers.

• Grip the nut (M6) on the blade plug with a pliers and pull out the blade plug.

• Then, shorten the connecting cable to the desired length.

• If the separate housing has to be mounted in a different room than the probe, you can now route the connecting cable through the wall.

• You can now reassemble the device by following the reverse order of steps.

Note!

• If you shorten the connecting cable, we recommend reusing all strands with ring terminals.

• If the strands are not to be reused, the crimp connections of the new ring terminals attached must be insulated with a heat-shrinking sleeve tube, for example (danger of short circuit).

• All soldered joints must be insulated. Use heat-shrinking sleeves to do so.

Caution! Before connecting the supply voltage, note the following:

• The supply voltage must match the information specified on the nameplate (see Page 10).

• Switch off the supply voltage before connecting the device.

• Connect the potential equalization to the ground terminal at the sensor.

Note!

• 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.

4.1 Connection recommendation

4.1.1 Potential equalization

Connect the potential equalization to the outer ground terminal of the housing (T13, F13, F16, F17). In the case of the stainless steel housing F15, the ground terminal (depending on the version) can also be located in the housing. For additional safety instructions, refer to the separate documentation for applications in hazardous areas.

4.1.2 Electromagnetic compatibility (EMC)

• Interference emission to EN 61326, Electrical Equipment Class B

• Interference immunity in accordance with EN 61326, Appendix A (Industrial) and NAMUR Recommendation NE 21 (EMC).

4.1.3 Cable specification

The electronic inserts can be connected using the usual commercial instrument cables. When using shielded instrument cables, it is recommended to connect the shielding on both sides to optimize the shielding effect (if potential equalization present).

6.2.2 Setting the measuring range

Note!

• The choice of measuring range (0 to 500 pF and 0 to 1600 pF) depends on the function of the probe.

• If the probe is used as a limit switch, you can retain the factory setting of 0 to 500 pF.

• If the probe is used for two-point control, the following recommendations apply for vertical installation: – Measuring range from 0 to 500 pF for probe lengths up to 1 m – Measuring range from 0 to 1600 pF for probe lengths up to 20 m

Partially insulated probes are only suitable for nonconductive bulk solids (see also  Chap. 8 on  ä 77).

To set the range to 0 to 1600 pF, proceed as follows:

1. Turn the function switch to position 4.

2. Press the "–" key for at least 2 seconds until the green LED 2 lights up.

3. Release the "–" key when the green LED 2 lights up.

Turn the function switch to position 2 to continue the calibration.

Note!

• The empty calibration stores the capacitance value of the probe when the tank is empty. If the measured capacitance value is, for example, 50 pF (empty calibration), a switching threshold of 2 pF is added to this value. The capacitance value of the switch point would, in this case, be 52 pF.

• The switching threshold depends on the value set for the switch point adjustment (for more information, see  ä 59).

To carry out an empty calibration, proceed as follows:

1. Check to make sure that the probe is not covered with product.

2. Turn the function switch to position 2.

3. Press the "–" key for at least two seconds.

4. Release the "–" key when the green LED 1 starts to flash.

The process of saving the empty calibration is finished when the green LED 1 lights up continuously. You can turn the function switch back to position 1 to return to operation.

6.2.4 Carrying out full calibration

Note!

• The full calibration measures the capacitance value of the probe when the tank is full. If the measured capacitance value is, for example, 100 pF (full calibration), a switching threshold of 2 pF is subtracted from this value. The capacitance value of the switch point is thus 98 pF.

• The switching threshold depends on the value set for the switch point adjustment (for more information, see  ä 59).

To carry out a full calibration, proceed as follows:

1. Make sure that the probe is covered by the medium up to the desired switch point.

2. Turn the function switch to position 2.

3. Press the "+" key for at least two seconds.

4. Release the "+" key when the green LED 5 starts to flash.

The process of saving the full calibration is complete when the green LED 5 lights up continuously. You can turn the function switch back to position 1 to return to operation.

6.2.5 Carrying out empty and full calibration

Note!

• An empty and full calibration provides the greatest possible operational security. This is particularly recommended for critical applications.

• The empty and full calibration measures the capacitance values of the probes when the tank is full and when it is empty. If, for example, the measured capacitance value of the empty calibration is 50 pF and that of the full calibration is 100 pF, the average capacitance value, 75 pF, is stored as the switch point.

To carry out an empty calibration, proceed as follows:

1. Check to make sure that the probe is not covered with product.

2. Turn the function switch to position 2.

3. Press the "–" key for at least two seconds.

4. Release the "–" key when the green LED 1 starts to flash.

The process of saving the empty calibration is finished when the green LED 1 lights up continuously. You can turn the function switch back to position 1 to return to operation.

To carry out a full calibration, proceed as follows:

1. Make sure that the probe is covered by the medium up to the desired switch point.

2. Turn the function switch to position 2.

3. Press the "+" key for at least two seconds.

4. Release the "+" key when the green LED 5 starts to flash.

6.2.7 Setting the switch point adjustment

Note!

• If only one calibration (empty or full) was carried out, and if buildup forms on the rod probe while the probe is in operation, the device may no longer respond to changes in level. A switch point adjustment (e.g. 4, 8, 16, 32 pF) compensates for this condition and ensures that you obtain a constant switch point again.

• For media that do not have a tendency to build up, we recommend a setting of 2 pF, as the probe is most sensitive to changes in level at this setting.

• For media with heavy buildup (e.g. plaster), we recommend using probes with active buildup compensation.

• A switch point adjustment can be carried out only if a full or empty calibration has been carried out first.

• A switch point adjustment is not possible if an empty and a full calibration have been carried out.

• The switch point adjustment is disabled if you switch on the two-point control (as described on  ä 60).

To adjust the switch point, proceed as follows:

1. Turn the function switch to position 3.

The green LED 1 lights up (factory setting).

2. Press the "+" key for at least two seconds to switch to the next higher value. If you press and

hold down the "+" or "–" key, the value changes to the next one every two seconds. The active value is indicated by an LED (1 to 5).

After you have carried out the switch point adjustment, turn the function switch to position 1 to return to operation.

6.2.8 Configuring two-point control and buildup mode

Note!

• In the case of non-conductive bulk solids, vertically installed probes can also be used for two-point control. The switchpoints of the empty and full calibration activate, for example, a handling device. If you want to use the two-point control, please note the following: – Set the necessary measuring range. For more information, see  ä 54: "Setting the measuring

range". – Perform empty and full calibration. – Set the failsafe mode (MIN/MAX) in accordance with your requirements. For more

information, see  ä 63.

• If you switch on the two-point control (s mode), the switch point adjustment (as described on

 ä 59) is disabled. The switch points correspond to the calibration points.

• The "Buildup mode" ensures that a safe switch point is output even if the probe is not fully released from the conductive medium (> 1000 μS/cm e.g. gypsum). Deposits or buildup on the rod/rope are compensated for.

To configure the two-point control and/or buildup mode, proceed as follows:

1. Turn the function switch to position 4.

2. Press the "+" key for at least two seconds to switch on the two-point control. The green

LED 5 lights up.

3. Press the "+" key again for at least two seconds to switch on buildup mode. Green LEDs 4

and 5 light up. – Pressing the "+" again for at least two seconds switches off both functions. Green LEDs 4

and 5 are off.

4. After you have configured the desired setting, turn the function switch to position 1 to return

to operation.

You have now completed the settings for the two-point control and buildup mode.

6.2.9 Setting the switching delay

Note!

• The switching delay causes the device to signal the level limit after a delay. This is particularly useful in tanks with turbulent medium surfaces caused, for example, by the filling process or by collapsing mounds. By doing so, you ensure that the filling of the tank does not end until the probe is continuously covered by the medium.

• A switching delay that is too short may, for example, cause the filling process to be restarted as soon as the medium surface settles.

Caution! If too long of a switching delay is set, this can cause the tank to overflow.

To set the switching delay, proceed as follows:

1. Turn the function switch to position 5.

2. Press the "+" key for at least two seconds to select the next higher value. Hold the "+" or "–"

keys down to skip from one value to another. The possible values are signaled by the LEDs 1 to 4.

3. Set the desired value.

You have now set the switching delay and can turn the function switch back to position 1 (operation).

6.2.10 Activating the self-test (function test)

Caution! Make sure that you do not accidentally activate any processes with the self-test! This could result, for example, in overflowing of the tank.

Note! The self-test simulates switching states (probe not covered, probe covered). This allows you to check if the connected devices are activated correctly.

To carry out a self-test, proceed as follows:

1. Turn the function switch to position 6.

2. Press the "+" and "–" keys simultaneously for at least two seconds. The self-test is active when the green LED 5 flashes. The green operational LED 1 is off.

3. After approx. 20 seconds, the test is completed. This is indicated by the lighting up of the operational LED 1.

You have now carried out the self-test and can turn the function switch back to position 1 (operation).

6.2.11 Setting the MIN/MAX and SIL failsafe mode

Note! The SIL mode function is only available in conjunction with electronic insert FEI55.

Note! By selecting the failsafe mode correctly, you ensure that the output always operates safely with quiescent current.

– Minimum failsafe mode (MIN): The output switches if the switch point is undershot (rod/rope

uncovered), a fault occurs or the line voltage fails.

– Maximum failsafe mode (MAX): The output switches if the switch point is exceeded (rod/

rope covered), a fault occurs or the line voltage fails.

To set the MIN or MAX failsafe mode, proceed as follows:

1. Turn the function switch to position 7.

2. Failsafe mode – Press the "–" key for at least two seconds to set the MIN failsafe mode. The green LED 1

starts to light up.

– Press the "+" key for at least two seconds to set the MAX failsafe mode. The green LED 5

6.2.12 Upload/download sensor DAT (EEPROM)

Note!

• The customer-specific settings of the electronic insert (e.g. empty/full calibration, switch point adjustment) are stored automatically in the sensor DAT (EEPROM) and in the electronic insert.

• The sensor DAT (EEPROM) is updated automatically each time a parameter is changed in the electronic insert.

• When replacing the electronic insert, all the sensor DAT (EEPROM) data are transferred to the electronic insert by means of a manual upload. No additional settings are required.

• If, for example, you need to transfer the customer-specific settings of an electronic insert to multiple sensor DATs (EEPROMs), you must carry out a manual download after installing the electronic insert.

– Upload: An upload transfers the saved data from the sensor DAT (EEPROM) to the electronic

insert. The electronic insert does not have to be configured any more, and the device is then operational.

– Download: A download transfers the saved data from the electronic insert to the sensor DAT

(EEPROM).

To carry out a sensor upload/download, proceed as follows:

1. Turn the function switch to position 8.

2. Press the "–" key for at least two seconds to carry out a download (the data from the electronic

insert are transferred to the sensor DAT (EEPROM). During the download, the green LED 1 flashes.

3. Press the "+" key for at least two seconds to carry out an upload (the data from the sensor DAT

(EEPROM) are transferred to the electronic insert). The green LED 5 flashes during upload.

You have now transmitted the data and can turn the function switch back to position 1 (operation).

6.4.2 Performing calibration

Note!

• An empty and full calibration provides the greatest possible operational security. This is particularly recommended for critical applications.

Carrying out empty calibration

To carry out an empty calibration, proceed as follows:

1. Check to make sure that the probe is not covered with product.

2. Before calibrating, select the "uncovered" probe state on DIP switch D.

3. Press keys A and B simultaneously for at least 2 s to save the calibration value.

4. The green LED 1 flashes quickly to indicate that the value has been saved correctly.

The process of saving the empty calibration value is finished once green LED 1 flashes slowly again.

Carrying out full calibration

To carry out a full calibration, proceed as follows:

1. Make sure that the probe is covered by the medium up to the desired switch point.

2. Before calibrating, select the "covered" probe state on DIP switch D.

3. Press keys A and B simultaneously for at least 2 s to save the calibration value.

4. The green LED 1 flashes quickly to indicate that the value has been saved correctly.

The process of saving the empty calibration value is finished once green LED 1 flashes slowly again.

6.4.3 Setting the switch point adjustment

Note the following when selecting switch point adjustment:

• If only one calibration (empty or full) was carried out, and if buildup forms on the rod probe while the probe is in operation, the device may no longer respond to changes in level. A switch point adjustment compensates for this condition and ensures that you obtain a constant switch point again.

• For media that do not have a tendency to build up, we recommend a setting of 2 pF, as the probe is most sensitive to changes in level at this setting.

• For media with heavy buildup (e.g. plaster), we recommend using probes with active buildup compensation and using the setting 10 pF.

6.4.4 Setting the switching delay

Note!

• A switching delay that is too short may, for example, cause the filling process to be restarted as soon as the medium surface settles.

Caution! If too long of a switching delay is set, this can cause the tank to overflow.

6.4.8 Test key C (open circuit)

Caution! This test can be used to activate safety-specific measures in the plant (e.g. alarms)!

Pressing test key C disconnects the supply voltage. If the power supply is disconnected, a supply unit such as Nivotester FTL325N from Endress+Hauser reacts in such a way that the alarm relay outputs an error and appropriate responses are triggered in any slave devices connected.

To perform the function test, proceed as follows:

1. Press test key C for the entire duration of the test.

The power supply from the supply unit is disconnected immediately.

2. All the LEDs go out. The safety functions (e.g. error message alarm) configured for the supply

unit are activated.

3. Release test key C again to end the function test.

7 Maintenance

No special maintenance work is required for the Solicap M point level switch.

Exterior cleaning

When cleaning the exterior of the Solicap M, make sure that the cleaning agent used does not corrode the housing surface or the seals.

Repair

In accordance with the Endress+Hauser repair principle, the devices have a modular design and repairs can be carried out by the customer. Spare parts are grouped logically into kits along with the respective replacement instructions. In Section 9.2 ( ä 79) you will find a list of all spare parts kits, together with their order numbers, that can be ordered from Endress+Hauser and used to repair the Solicap M. For more information about service and spare parts, contact Endress+Hauser Service.

Repairing Ex-certified devices

The following information also has to be taken into account for repairs of Ex-certified devices:

• Ex-certified devices may be repaired only by experienced, skilled staff or by Endress+Hauser Service.

• Applicable standards, federal/national Ex standards and the Safety Instructions (XA) and certificates must be observed.

• Only genuine spare parts from Endress+Hauser may be used.

• When ordering spare parts, please note the device designation on the nameplate. Parts can only be replaced by the same parts.

• Repairs must be carried out according to the instructions. Following the repair, the individual testing specified for the device must be carried out.

• Certified devices can only be converted into other certified devices by Endress+Hauser Service.

• Every conversion and repair made to the device must be documented.

Replacement

After replacing a Solicap M unit or the electronic insert, the calibration values must be transmitted to the replacement unit.

– If a probe is replaced, the calibration values are transferred to the Sensor DAT (EEPROM) by

means of a manual download in the electronic insert.

– If the electronic insert is replaced, the calibration values are transferred to the electronics by

means of a manual upload in the Sensor DAT (EEPROM).

This means that you can restart the device without having to carry out a new calibration (see also  ä 65).

9.1 Fault diagnostics in the electronic insert

Note! In the event of faults during commissioning or operation of the device, you have the ability to carry out fault diagnostics on the electronic insert. This function is supported by the electronic inserts FEI51, FEI52, FEI54, FEI55 (see error table 1 and 2 below).

The electronic inserts FEI53, FEI57S and FEI58 signal two types of faults:

• Faults that can be rectified: The red LED flashes.

• Faults that cannot be rectified: The red LED is lit continuously.

For additional information on fault detection and fault elimination, refer to fault table 2 below.

9.1.1 Activating fault diagnostics FEI51, FEI52, FEI54, FEI55

Note! The diagnostics provide information about the operating status of the device. The results of the diagnostics are displayed by LEDs 1, 2, 4 and 5. If the diagnostics detect multiple faults, these are shown according to their priority. A serious fault (e.g. priority 3) is always displayed before a less serious fault (e.g. priority 5).

To activate the fault diagnostics, proceed as follows:

1. Set the function switch to position 1 (operation).

2. Press the "–" key.

3. "Fault table 1" lists possible causes of faults and information on how to eliminate them.
