6 Functional safety (SIL) 6 Functional safety (SIL) 6.1 Objective In case of dangerous outages, processing facilities and machines can cause risks for persons, environment and property. The risk of such outages 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 security depending on the correct functioning of safety-related components for risk reduction is called functional safety.
6 Functional safety (SIL) • Tool for operation and parameterization 4 … 20 mA current output 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 conjunction with an adjustment software according to the FDT/DTM standard, e. g. PACTware Note: For operation of the VEGAFLEX 83 the DTM Collection version 1.
6 Functional safety (SIL) Change parameter All parameters changed by the operator are automatically stored temporarily so that they can be verified in the next step. Verify parameters/Lock adjustment After setup, the modified parameters must be verified (confirm the correctness of the parameters). To do this, you first have to enter the PIN. Here the adjustment is locked automatically. Then you carry out a comparison of two character strings. You must confirm that the character strings are identical.
6 Functional safety (SIL) Setup is then finished. Function test required Should a function test be necessary, the following message is displayed on the display and adjustment module. The adjustment software also signals that a function test is required. If a function test is required, the switching point or the range must be controlled with the original medium. For this purpose, you have to decide for your application which condition is potentially critical.
6 Functional safety (SIL) Measure the current output and compare the value with the calculated current value. You have to determine the permissible deviation of the values yourself. This deviation depends on the the accuracy requirements of your measurement loop. Determine the permissible tolerance for the deviation. Mode "Range monitoring" If both levels are important for the safety function, you have to proceed according to the mode "Range monitoring". 1.

With the "+" key you change the sign and with the "->" key you jump to the next position. You can enter names with max. 19 characters.
7 Set up with the display and adjustment module Note: The selection of the application has a considerable influence on all other menu items. Keep in mind that as you continue with the parameter adjustment, individual menu items are only optionally available. You have the option of choosing the demonstration mode. In this mode, the sensor ignores the parameters of the application and reacts immediately to any change.
7 Set up with the display and adjustment module You can enter the dielectric constant of the upper medium directly or have the value determined by the instrument. To do this you have to enter the measured or known distance to the interface. Setup - Max. adjustment Level In this menu item you can enter the max. adjustment for the level. With interface measurement this is the maximum total level. Adjust the requested percentage value with [+] and store with [OK].
7 Set up with the display and adjustment module Setup - Max. adjustment - This menu item is only available if you have selected interface measInterface urement under the menu item "Application". You can accept the adjustment of the level measurement also for the interface measurement. If you select "Yes", the current setting will be displayed. If you have selected "No", you can enter the adjustment for the interface separately. Enter the requested percentage value.
7 Set up with the display and adjustment module The default setting is a damping of 0 s. Setup - Linearization A linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. a horizontal cylindrical or spherical tank, when the indication or output of the volume is required. Corresponding linearization curves are preprogrammed for these vessels. They represent the correlation between the level percentage and vessel volume.
D -h +h 7 Set up with the display and adjustment module Fig. 28: Vessel height und socket correction value D Vessel height +h Positive socket correction value -h Negative socket correction value Since scaling is very extensive, scaling of the level value was divided into two menu items. Setup - Scaling Level 1 In menu item "Level 1" you define the scaling variable and the scaling unit for the level value on the display, e.g. volume in l.
7 Set up with the display and adjustment module Setup - Scaling Level 2 Since scaling is very extensive, scaling of the level value was divided into two menu items. In menu item "Level 2" you define the scaling format on the display and the scaling of the measured level value for 0 % and 100 %. Setup/Scaling Interface Since scaling is very extensive, scaling of the interface value was divided into two menu items.
7 Set up with the display and adjustment module Setup - Current output mode In the menu item "Current output mode" you determine the output characteristics and reaction of the current output in case of failure. The default setting is output characteristics 4 … 20 mA, failure mode < 3.6 mA. Setup - Current output Min./Max. In the menu item "Current output Min./Max.", you determine the reaction of the current output during operation. The default setting is min. current 3.8 mA and max. current 20.5 mA.
7 Set up with the display and adjustment module In the menu "HART variables 1" you can have the first HART value PV (primary value) and the second HART value SV (secondary value) of the sensor displayed. The values cannot be changed in the display and adjustment module. To change these values, you have to use the adjustment software PACTware. HART functions are not relevant for SIL applications.
7 Set up with the display and adjustment module Note: Check the distance to the product surface, because if an incorrect (too large) value is entered, the existing level will be saved as a false echo. The filling level would then no longer be detectable in this area.
7 Set up with the display and adjustment module In this case, you have to carry out a function test. Function test During a function test, you have to test the safety function of the instrument in the vessel with the original medium. For this purpose, you should know the filling height of the vessel as well as the min. and max. levels respectively for 4 and 20 mA. You then can calculate the respective output current.
7 Set up with the display and adjustment module To interrupt the function test, you have to push the button "ESC". If you carry out the function test by means of the "PACTware" software, you can store the previously performed tests and continue from there later on. Display In the main menu point "Display", the individual submenu points should be selected subsequently and provided with the correct parameters to ensure the optimum adjustment of the display options.
