Does not switch 

No Power 

Check power 

Faulty signal line 

Check signal line 

Faulty electronic Module 

Replace Module 

Density of liquid too low 

Set density to > 0.5 at electronic insert 

Fork encrusted 

Clean fork 

Fork corroded 

Exchange fork and process connection 

Contacts welded together (after 
short-circuit) 

Replace Module; put fuse in contact circuit 

Switches  
incorrectly 

Min- / Max– fail-safe mode set 
wrong 

Set correct mode at electronic insert 

Thick heavy foam, very turbulent 
conditions, foaming liquid 

Mount Resonator Switch in a bypass line 

 
 
 
Sporadic faulty  
switching 

Extreme RFI 

Use shielded cable 

Extreme vibration 

Decouple, damp, turn fork 90° 

Water in housing 

Screw cover and cable gland tight
