Priority when dry run and high water signals are present simultaneously

If the system malfunctions, it may happen that both signals are present at the same time. In this case, the priority is dependent upon the selected operating mode and thus the reaction of the switchgear:

• Operating mode “drain”
• 1. Dry-running protection
• 2. High water
• “Fill” operating mode
• 1. Dry-running protection/low water (via “Extern OFF” input)
• 2. High water
• 3. Min. water level
