Switch-on phase

After connecting SITRANS LG260 to the bus system, the device first
performs a self-test:
•
Internal check of the electronics
•
Indication of the status message "F 105 Determine measured
value" on the display or PC
•
Status byte goes to fault value
Then the actual measured value is output to the signal cable. The
value takes into account settings that have already been carried out,
e.g. default setting.
