3.2 Principle of operation
VEGAMET 391 mit SIL-Qualikation is a universal signal conditioning
instrument for a variety of applications such as level, gauge and pro-
cess pressure measurement. At the same time, it can serve as power
supply unit for connected sensors. VEGAMET 391 mit SIL-Qualika-
tion is designed for connection of any 4 … 20 mA sensor.
Due to the SIL qualication, the instrument can be used in a safety-
relevant protective function. With single channel architectur, SIL2 is
reached, with multiple channel, diversitary architecture, SIL3. Take
note of the specications and requirements of the "Safety Manual".
The VEGAMET 391 mit SIL-Qualikation signal conditioning instru-
ment can power the connected sensor and process its measurement
signals.The requested parameter is shown on the display and also
outputted to the integrated current output for further processing. The
measurement signal can thus be transferred to a remote display or a
superordinate control system. Operating relays for control of pumps or
other devices are also integrated.

VEGAMET 391 • With SIL qualication
38704-EN-170907
6 Functional safety (SIL)
6.1 Directive and scope
In case of dangerous failures, processing facilities and machines can
cause risks for persons, environment and property. The risk of such
failures must be judged by the plant operator. Dependent thereon are
measures for risk reduction through error prevention, error detection
and fault control.
The part of plant safety depending on the correct functioning of
safety-related components for risk reduction is called functional
safety. Components used in such safety-instrumented systems (SIS)
must therefore execute their intended function (safety function) with a
dened high probability.
The safety requirements for such components are described in
the international standard IEC 61508, which sets the measure for
unique and comparable judgement of instrument safety and hence
contributes to worldwide legal certainty. Depending on the degree
of required risk reduction, we distinguish between four safety levels,
from SIL1 for low risk to SIL4 for very high risk (SIL = Safety Integrity
Level).
6.2 SILqualication
In the development of instruments used in safety-instrumented sys-
tems, avoiding systematic errors as well as determining and correct-
ing random errors is given great importance.The operator also gets
information that helps him full the requirements on the functional
safety of his system.
Here the most important characteristics and requirements from the
perspective of functional safety according to IEC 61508:
• Internal monitoring of safety-relevant circuit parts
• Extended standardization of the software development
• In case of failure, switching of the safety-relevant outputs to a
dened safe state
• Determination of the failure probability of the dened safety func-
tion
• Reliable parameterization with non-safe user environment
• Recurring function test
The SIL qualication of components is specied in a manual on func-
tional safety (Safety Manual). Here, you can nd all safety-relevant
characteristics and information the user and the planner need for
planning and operating the safety-instrumented system.This docu-
ment is attached to each instrument with SIL rating and can be also
found on our homepage via the instrument search.
6.3 Application area
The signal conditioning instrument is used in combination with a SIL
qualied 4 … 20 mA sensor if safety-relevant protective functions are
required.
Additional characteristics
and requirements

18
6 Functional safety (SIL)
VEGAMET 391 • With SIL qualication
38704-EN-170907
The following inputs/outputs are permitted:
• 4 … 20 mA sensor input with transmitter power supply
• Relay outputs 3/4
• 4 … 20 mA current output
Note:
The following inputs/outputs are not permitted for safety-relevant
applications:
• Digital input 1/2
• Relay output 1/2
• Measured value transmission via the communication interfaces
(USB/HART)
6.4 Safety concept of the parameterization
The following tools are permitted for parameterization of the safety
function:
• The integrated display and adjustment unit for on-site adjustment
• The DTM suitable for the signal conditioning instrument in con-
junction with an adjustment software according to the FDT/DTM
standard, e. g. PACTware
Note:
For operation of the VEGAMET 391 mit SIL-Qualikation the DTM
Collection 06/2011 or higher is required. The modication of safety-
relevant parameters is only possible with active connection to the
instrument (online mode).
To avoid possible errors during parameterization in a non-safe user
environment, a verication procedure is used that makes it possible
to detect parameterization errors reliably. For this, safety-relevant
parameters must be veried before they are stored in the device. In
normal operating condition, the instrument is also locked against
parameter changes through unauthorized access.This concept ap-
plies to the adjustment on the instrument but also to adjustment with
PACTware with DTM.
All safety-relevant parameters must be veried after a change and
conrmed by a character string comparison. The following parameters
of the relays 3/4 are judged as safety-relevant:
• Mode relay output
• Relay switching point Hi
• Relay switching point Lo
The parameter settings of the measurement loop must be document-
ed. For this purpose, the document "SIL device settings" is attached
to each instrument already listing all safety-relevant parameters in
the shipping status as well as containing free space for own notes.
This document is also available via the instrument search on our
homepage. In addition, a list of the safety-relevant parameters can be
stored and printed via PACTware/DTM.

6 Functional safety (SIL)
VEGAMET 391 • With SIL qualication
38704-EN-170907
For each parameter change, the instrument must be unlocked via
a PIN (see chapter "Setup steps - Unlock adjustment"). The device
status is indicated via the symbol of an unlocked or locked padlock.
Warning:
If the instrument is unlocked, the safety function must be classied as
unsafe. This applies until the parameterization is terminated correctly.
If necessary, other measures must be taken to maintain the safety
function.
All parameters changed by the operator are marked automatically so
that they can veried in the next step.
For the verication the PIN must be entered rst and a comparison of
two character strings must be carried out. The user must conrm that
both character strings are identical, this is used to check the charac-
ter representation and the communication channels. The verication
texts are provided in German and with all other menu languages in
English.
In a second step, all the modied, safety-relevant parameters that are
listed must be conrmed. After this process is nished, the adjust-
ment mode will be locked automatically and the safety function is
guaranteed again.
Warning:
If the described process was not carried out completely or correctly
(e.g. interruption or voltage loss), the instrument remains in unsafe
and unlocked status.
Warning:
In case of a reset to basic settings, all safety-relevant parameters will
also be reset to default. Therefore all safety-relevant parameters must
be checked or readjusted.
