Introduction

! Note! For general information about SIL please refer to: www.endress.com/sil

and in the Competence Brochure CP002Z "Safety in the Process Industry – reducing risks with SIL"

Structure of the measuring system with Soliphant M with FEM57 + Nivotester FTL325P

Level limit measuring system The measuring system is displayed in the following diagram (example).

L00-FTM5xxxx-16-06-xx-en-002

Safety function The safety function applies to all settings in MAX safety (monitoring of the covered state) and use of the NO contacts of the level relays.

The MAX safety setting has the effect that the level relay always works in quiescent current safety; i.e. the relay contact opens when:

• the switch point is exceeded (level exceeds response height)• a fault occurs• mains voltage fails

In addition to the level relay, the alarm relay works in operating current safety and closes the contact, when:

• one of the following faults occurs:– the sensor connection is interrupted– the sensor connection short circuits– the sensor identifies corrosion at the vibration system

• mains voltage fails

The measuring range of Soliphant M depends on the medium, mounting location and fork length.

The detection range is within the length of the fork and depends on the weight of the medium and the resulting type of fork:

• Standard fork with a length of 155 mm (Density of medium ≥ 10 g/l) and• Short fork with a length of 100 mm (Density of medium ≥ 50 g/l)

Supplementary device documentation

The following must be available for the measuring system:

Settings and installation instructions

Installation instructions The ambient conditions for the Nivotester FTL325P must correspond to IP54 (as per EN 60529).

Please refer to the Compact Instructions (KA) for information regarding the correct installation ofSoliphant M with FEM57. Since the application conditions have an effect on the safety of the measurement, pay attention to the notes in the Technical Information (TI) and Compact Instructions (KA).

Refer to the following documentation for instructions on setting the instruments:

Settings for Soliphant M with FEM57

The density switch setting has an influence on probability of failure and function test type (see Chapter "Appendix").The test mode setting has influence on the function test (see Chapter "Recurrent function tests of the measuring system").

! Note! The SIL evaluation for the Soliphant M comprises the complete device, including the Nivotester, the electronics insert, the tuning fork with piezo drive, the process connection and the internal wiring.

In applications with extremely strong external vibrations > 0.05 g2/Hz and light weight bulk solids < 600 gr/l a functional test is recommended!

" Caution! Changes to the settings at the electronic insert FEM57 after measuring system start-up can impair the safety function!

Settings for Nivotester FTL325P-#3#3 (3 channel)

It is recommended to leave the switching elements following the overfill protection in the safe state until the alarm signal has been acknowledged.

One switch for switching delay

0.5 s when covered, 1.5 s when uncovered (short fork 1 s)

5 s when covered, 5 s when uncovered

One switch for bulk density/density setting

≥ 50 g/l standard fork, ≥ 200 g/l short fork (high bulk density)

≥ 10 g/l standard fork, ≥ 50 g/l short fork (low bulk density)

One switch for diagnosis

OFF Diagnosis of abrasion and build-up switched OFF. ON Diagnosis of abrasion and build-up switched ON.

• For additional density setting to high bulk density: abrasion and build-up are indicated per LED at the electronic insert only

• For additional density setting to low bulk density: output of "signal on alarm" for abrasion and build-up

" Caution! Observe the following for the Nivotester FTL325P:The operator must use suitable measures (e.g. current limiter, fuses) to ensure the relay contact characteristics are not exceeded:

• U ≤ 253 V AC 50/60 Hz , I ≤ 2 A, P ≤ 500 VA at cos ϕ ≥ 0.7 or• U ≤ 40 V DC, I ≤ 2 A, P ≤ 80 W

" Caution! Changes to the measuring system and settings after start-up can impair the protection function!

Response in operation and failure

The response in operation and failure is described in the following documentation:

Failure rates of electrical components

The underlying failure rates of electrical components are specified for the useful lifetime according toIEC 61508-2 Section 7.4.7.4. Note 3.

Repair

If a SIL-marked device that has been operated in a functional safety application fails, the "Declaration of Hazardous Material and De-Contamination" form containing the appropriate information "Used as a SIL device in a Safety Instrumented System" must be enclosed with the defective device when it is returned.

Recurrent function tests of the measuring system

The operativeness of the overfill protection must be checked periodicaly if the PFDavg values given in the Appendix are used. The check must be carried out in such a way that it is proven that the overfill protection functions perfectly in interaction with all components. This is guaranteed when the response height is approached in a filling process. If it is not practical to fill to the response height, suitable simulation of the level or of the physical measuring effect must be used to make the level sensor respond. If the operativeness of the level sensor/transmitter can be determined otherwise (exclusion of faults that impair function), the check can also be completed by simulating the corresponding output signal.

" Caution! Note the following points for the function test: • Test each channel individually by pressing the associated test key.• Check the electrical switching of relay contacts, e.g. using a hand multimeter connected to the terminals.• In multi-channel devices, all channels which do not carry out a safety function must be included in the

recurrent function tests if faulty functioning cannnot be detected by any other means - e.g. by means of independent protective measures or changing the response of the measuring point.

• A positive test result is optained when the system reaction corresponds to the description.• If the system reaction does not correspond to the described procedure, the monitored process

must be kept in a safe state by additional or different measures until the safety system is repaired.
