Operating behavior
As the trip mode Max or Min are possible, as the operating mode Active or Passive are possible.
Areas of application:
• Trip mode Max, operating mode Active: alarm if the signal is above the trip value, e. g. horn on;
protection against overfilling, e. g. open drain in capacity tank
• Trip mode Max, operating mode Passive: protection against overfilling, e. g. conveyor belt/pump
off; for a large hysteresis Min-Max operation, e. g. conveyor belt/pump on/off
• Trip mode Min, operating mode Active: alarm if the signal is below the trip value, e. g. horn on;
protection against shortfalls in security reserves, e. g. conveyor belt/pump on
• Trip mode Min, operating mode Passive: Protection against shortfalls in security reserves, e. g.
pumping out off; for a large hysteresis Min-Max operation
