Fail-safe mode

MIN-/MAX detection on the electronic insert, switchable.

MIN

The output switches if the probe is uncovered or if the supply voltage is disconnected in a safety-

oriented manner (signal on alarm). Used for dry-running protection and pump protection, for example.

MAX

The output switches if the probe is covered or if the supply voltage is disconnected in a safety-oriented

manner (signal on alarm). Used for overfill protection, for example.
