Introduction
!
Note!
For general information about SIL please refer to: /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 FEM55
Level limit measuring system
The measuring system is displayed in the following diagram (example).
Soliphant M with electronics insert FEM55: two-wire connection (8/16 mA H-L edge) for separate switching device with transistor output
Safety function The safety function only applies to MAX safety (overfill protection).The output current is less than 12 mA when:
•The switch point is exceeded (level exceeds response height)•A fault occurs
•The 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)

Permitted versions of the Soliphant M with FEM55 for the safety function The following combinations are permitted for the measuring system:•FTM50-#####5#####•FTM51-#####5#####•FTM52-#####5#####
Permitted instrument types (# = all instrument versions permitted excepting 9 and Y)•Valid FW version (firmware): V01.00.00 or higher •Valid HW version (hardware): V01.00 or higher Safety function data
The mandatory settings and data for the safety function can be found in the Appendix (Page 9).The measuring system reacts in ≤ 0.9 s.
!
Note!
MTTR is set at 8 hours under the condition that the electronics insert is on stock.
Safety systems without a self-locking function must be monitored or set to an otherwise safe state after carrying out the safety function within MTTR.

The following must be available for the measuring system:
Settings and installation instructions
Installation instructions
Please refer to the Compact Instructions (KA) for information regarding the correct installation of Soliphant M with FEM55.
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).

Settings for Soliphant M with FEM55
Connectable load:•The maximum threshold for an alarm is 12 mA
•The monitoring of the current error limits at 3,6 and 21,0 mA must be activated •R = (U - 11 V) / 16.8 mA
•
U = connection DC voltage 11…36 V
!
Note!
The SIL evaluation for the Soliphant M comprises the complete device, including 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 g 2/Hz and light weight bulk solids < 600 gr/l a functional test is recommended!
It is recommended to leave the switching elements following the overfill protection in the safe state until thealarm signal has been acknowledged.
"
Caution!
Changes to the settings at the electronic insert FEM55 after measuring system start-up can impair the safety function!
Switch setting for the safety function:
One switch for safety mode MAX Overfill protection MIN Dry running protection
One switch for switching delay
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

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 to IEC 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 PFD avg 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.
In the case of recurrent tests, each permitted setting must be checked, especially if all the alarm switches at the Nivotester are set to ON.
"
Caution!
Note the following points for the function test:
•Relay contact switching can be checked by using a hand multimeter at the terminals or by observing the overfill protection elements (e.g. horn, adjuster).
•As a positive test result, a covered tuning fork must be detected and trigger the alarm for overfill protection.•If fork covering is not detected during the recurrent test, the monitored process must be set to a safe state by means of additional or other measures and/or kept in the safe state until the safety system is repaired.
