If the floating probe is used for minimum level detection, the control unit trig-
gers an alarm as soon as the liquid level falls below the switching level.
If the floating probe is used for maximum level detection, the control unit trig-
gers an alarm as soon as the liquid level exceeds the switching level.
Operating the product is limited to its regular monitoring:
• The green LED is on.
• The red LED is off.

You can mute the audible alarm by pressing the "Acknowledge" key. Press

restored, the product immediately resumes operation.
