your measurement loop. Determine the permissible tolerance for the
deviation.
If you have to interrupt the function, you can leave the SITRANS
LG250 in the respective situation.
As long as SITRANS LG250 is powered, the display and adjustment
module remains in the currently set adjustment menu.
To interrupt the function test, you have to push the button "ESC".
If you carry out the function test by means of the "PACTware" soft-
ware, you can store the previously performed tests and continue from
there later on.
Verify parameter
All safety-relevant parameters must be verified after a change. After
the function test, all modified, safety-relevant parameters will be
listed. Confirm the modified values one after the other.
If the described process of parameter adjustment was run through
completely and correctly, the instrument will be locked and hence
ready for operation.
Otherwise the instrument remains in the released and hence unsafe
condition.
If you have to interrupt the function test, you can leave the display and
adjustment module of SITRANS LG250 in its current state.
As long as SITRANS LG250 is powered, the display and adjustment
module remains in the currently set adjustment menu.
To interrupt the function test, you have to push the button "ESC".
If you carry out the function test by means of the "PACTware" soft-
ware, you can store the previously performed tests and continue from
there later on.
Setup - Current output 2 If a supplementary electronics with an additional current output is in-
stalled in the instrument, you can adjust the additional current output
separately.
In menu item"Current output 2" you specify which measured value
the additional current output refers to.
The additional current output cannot be used as an output in the
sense of a safety-instrumented application (SIL).
The procedure corresponds to the previous settings of the standard
current output. See "Setup - Current output".
