• Minimum/maximum quiescent current safety can be switched at the electronic insert
• MAX = Maximum safety: When the tuning fork is covered, the output switches in the direction of
demand. Use this for overfill prevention, for example.
• MIN = Minimum safety: When the tuning fork is uncovered, the output switches in the direction of
demand. Use this for dry-running protection of pumps, for example.
