3.1.2 Overall status
Should general monitoring of all sensor signals via a single remote line
("OR-gate") be desired, remote line 2 can be switched on for monitoring
the overall status. Switch on DIP switch 2 for this purpose. This causes
remote line 2 to be activated as soon as a Level Full or Level Empty
status is reached.
Remote line 2 is activated whenever a random sensor signal reacts to
overflow or empty running.
3.1.3 Selective operating mode
The individual remote lines can be switched off selectively if they are not
required for monitoring purposes, i.e. when not all sensor connections are
assigned.
Example:
Monitoring overflow and empty level (incl.
overall status)
Level Empty 1
Level Full 1
Overall status
Example:
Monitoring overflow in two containers (incl.
overall status)
