Fig. 3: Type NB 220 H, Type NB 220 QS and Type NB 220 QSF transducers

Type NB 220 H transducer

With the Type NB 220 H transducer a relay drop-out is indicated by the yellow Sensor lamp ("Geber") going out (see Fig. 3).

Type NB 220 QS transducer

With the Type NB 220 QS transducer a relay drop-out is indicated by the yellow Sensor lamp ("Geber") going out, an audible signal and a visual signal. The audible signal can be cancelled by pressing the Acknowledge button ("Quittierung"). The visual signal (red "Alarm" lamp) remains on for the time being and goes out if the level detector emerges or a fault has been remedied (short circuit, open circuit between the level detector and the transducer). The Overfill Protection System is primed again when the red lamp goes out (see Fig. 3).

The above-mentioned alarm indicators can also be connected externally.
