9. Malfunctions and remedial measure faultsFaultsFault display control unitHigh water floater 2+ high watersensorWater level in the aeration chamberhas exceeded maximum level.Danger of plant overflowing.Causes- Level set too low- Feed quantity too high- Clear water syphon defective orclogged- Water cannot drain off.BackupElimination- Setting to 150 cm- Checking the plant's feed quantities- Checking the clear water syphon'shydraulic performanceand cleaning it if necessary- Providing free drainage in thesampling duct.Low water sensor:Water level in the aeration chamberhas dropped below the minimumlevel.- Level set too high- Plant not sufficiently filled aftermaintenance- Tank leaky- Setting to 80 cm- Filling the plant with 1.20 m ofwater- Sealing the tankExcess pressure:Exceeding the maximumset pressure of thepressure monitoring system- Pressure set too low- Compressor builds up excessivebackpressure:- Valve block does not switch- Vent hose is kinked- Air syphons are clogged- Aerator spark plug is clogged- Setting to 350 mbar- Checking and if necessary replacingthe valve block- Removing any kinks- Cleaning the air syphons- Cleaning the aerator spark plugNegative pressure:Falling below the maximum setpressure of the pressure monitoringsystem- Pressure is set too high- Compressor does not work orworks only inadequately- Leak inside the INNO-CLEAN ®system- Setting to 10 mbar- Checking the compressor'sefficiency (see chapter"Maintenance")- Checking all connections andhoses for possible leakagesOvercurrent(Current consumption too high)- Value set too low- Defect on the compressor- Setting to 2.0 A- Replacing the electrical componentsand if necessary testing bya qualified electricianUndercurrent(Current consumption too low)- Value set too high- Compressor does not switch on- Defective- Internal microfuse incontrol unit (3.15 A) has tripped- Setting to 0.1 A- Checking the compressor'smains connection on the controlunit- Replacement/ fuseBattery voltage too low- Battery defective or service life exceeded- Replacement battery125
