Determining the Safety

Integrity Level (SIL)

The achievable Safety Integrity Level is determined by the following safety-related parameters:

• Average Probability of Failure on Demand (PFDAVG)

• Hardware Fault Tolerance (HFT) and

• Safe Failure Fraction (SFF).

The specific safety-related parameters for the RMA422, as a part of a safety function, are listed in the "Safety-

related parameters" chapter.

The following table displays the dependence of the "Safety Integrity Level" (SIL) on the "Average Probability of

Failure on Demand" (PFDAVG). Here, the "Low demand mode" has been observed, i.e. the requirement rate for

the safety-related system is maximum once a year.

Sensor, process transmitter, logic unit and actuator together form a safety-related system, which performs a

safety function. The "Average Probability of Failure on Demand" (PFDAVG) is usually divided up into the sensor,

process transmitter, logic unit and actuator sub-systems as per Figure 1.

Fig. 1: Share of the process transmitter in the "average probability of dangerous failure on demand" (PFDAVG

This documentation considers the RMA422 as a component of a safety function.

Dangerous

failure

Failure with the potential to put the safety-related system in a dangerous or non-functional

condition.

Safety-related system A safety-related system performs the safety functions that are required to achieve or

maintain a safe condition e.g. in a plant. Example: temperature measuring device – logic

unit (e.g. limit signal generator) – valve form a safety-related system.

Safety function Defined function, which is performed by a safety-related system with the aim of achieving

or maintaining a safe condition for the plant, considering a specified dangerous incident.

Example: limit temperature monitoring

Safety Integrity Level RMA422 (Type B)

The following table displays the achievable "Safety Integrity Level" (SIL) of the entire safety-related system for

type B systems depending on the "Safe Failure Fraction" (SFF) and the "Hardware Fault Tolerance" (HFT). Type

B systems are, for example, sensors with complex components such as ASICs (→ see also IEC 61508, Part 2).

one (values in brackets), if the following conditions are true for devices using sensors and actuators with complex

components:

– The device is "proven in use".

– The device allows adjustment of process-related parameters only, e.g. measuring range, upscale or downscale

failure direction, etc.

– The adjustment level of the process-related parameters of the device is protected, e.g. by jumper, password (here:

numeric code or key combination)

– The function has a "Safety Integrity Level" (SIL) requirement less than 4.

All conditions are true for the RMA422.

G09-RMA422xx-14-00-xx-en-001

Fig. 3: Safety function with relay

The sensors, powered by the RMA422 process transmitter, generate an analog signal (4 to 20 mA) in proportion

to the measured value. Mathematic functions allow the formation of a new process variable. The process

transmitter makes the analog signals in proportion to the new process variable available to a downstream logic

unit, such as a PLC. The limit values can also be monitored directly with the RMA422 by means of 2 change-

over contacts.

Safety function data

" Caution!

The data for the safety functions are listed in the "Safety-related parameters" chapter.

! Note!

MTTR is set at eight hours.

Safety-related systems without a self-locking function must be monitored or set to an otherwise safe state after

carrying out the safety function within MTTR.

Supplementary device

documentation RMA422

Depending on the version, the following documentation must be available for the Process transmitter RMA422:

" Caution!

• The installation and setting instructions, and the technical limit values must be observed in accordance with

the Operating Instructions (BA103R).

• For devices which are used in explosion-hazardous, the supplementary documentation (XA) resp. Control

Drawings must also be used in accordance with the table.

Commissioning and iterative tests

Using the RMA422 for

continuous measurements

The operability of the safety installation must be tested at appropriate time intervals. It is the responsibility of

the user to select the type of check and the intervals in the specified time frame. The test must be completed

in such a way that the fault free function of the safety installation combined with all components can be

validated.

Settings

Settings It is possible to set up on the RMA422. When used as part of a safety function, an analog signal or a limit relay

can be used. Please refer to the following table for information on the settings which are permitted or not when

using the RMA422 in a safety-related application.

RMA422 with current output:

RMA422 with relay:

For further information see the BA103R operating instructions.

" Caution!

Check the safety function after entering all the parameters.

Locking Device operation has to be locked to protect the process-related parameters from being altered. This is done

using a code which is selected by the user.
