The sensor is operated via the four keys of the display and adjustment
module. The individual menu items are shown on the LC display. You
can find the function of the individual keys in the previous illustration.
When the [+] and [->] keys are pressed quickly, the edited value,
or the cursor, changes one value or position at a time. If the key is
pressed longer than 1 s, the value or position changes continuously.
When the [OK] and [ESC] keys are pressed simultaneously for more
than 5 s, the display returns to the main menu. The menu language is
then switched over to "English".
Approx. 60 minutes after the last pressing of a key, an automatic reset
to measured value indication is triggered. Any values not confirmed
with [OK] will not be saved.
After switching on, the SITRANS LG250 carries out a short self-test
where the device software is checked.
The output signal transmits a fault signal during the switch-on phase.
The following information is displayed on the display and adjustment
module during the startup procedure:
