9. Malfunctions and remedial measure faults<br />
Faults<br />
Fault display control unit<br />
High water floater 2+ high water<br />
sensor<br />
Water level in the aeration chamber<br />
has exceeded maximum level.<br />
Danger of plant overflowing.<br />
Causes<br />
- Level set too low<br />
- Feed quantity too high<br />
- Clear water syphon defective or<br />
clogged<br />
- Water cannot drain off.<br />
Backup<br />
Elimination<br />
- Setting to 150 cm<br />
- Checking the plant's feed quantities<br />
- Checking the clear water syphon's<br />
hydraulic performance<br />
and cleaning it if necessary<br />
- Providing free drainage in the<br />
sampling duct.<br />
Low water sensor:<br />
Water level in the aeration chamber<br />
has dropped below the minimum<br />
level.<br />
- Level set too high<br />
- Plant not sufficiently filled after<br />
maintenance<br />
- Tank leaky<br />
- Setting to 80 cm<br />
- Filling the plant with 1.20 m of<br />
water<br />
- Sealing the tank<br />
Excess pressure:<br />
Exceeding the maximum<br />
set pressure of the<br />
pressure monitoring system<br />
- Pressure set too low<br />
- Compressor builds up excessive<br />
backpressure:<br />
- Valve block does not switch<br />
- Vent hose is kinked<br />
- Air syphons are clogged<br />
- Aerator spark plug is clogged<br />
- Setting to 350 mbar<br />
- Checking and if necessary replacing<br />
the valve block<br />
- Removing any kinks<br />
- Cleaning the air syphons<br />
- Cleaning the aerator spark plug<br />
Negative pressure:<br />
Falling below the maximum set<br />
pressure of the pressure monitoring<br />
system<br />
- Pressure is set too high<br />
- Compressor does not work or<br />
works only inadequately<br />
- Leak inside the <strong>INNO</strong>-CLEAN ®<br />
system<br />
- Setting to 10 mbar<br />
- Checking the compressor's<br />
efficiency (see chapter<br />
"Maintenance")<br />
- Checking all connections and<br />
hoses for possible leakages<br />
Overcurrent<br />
(Current consumption too high)<br />
- Value set too low<br />
- Defect on the compressor<br />
- Setting to 2.0 A<br />
- Replacing the electrical components<br />
and if necessary testing by<br />
a qualified electrician<br />
Undercurrent<br />
(Current consumption too low)<br />
- Value set too high<br />
- Compressor does not switch on<br />
- Defective<br />
- Internal microfuse in<br />
control unit (3.15 A) has tripped<br />
- Setting to 0.1 A<br />
- Checking the compressor's<br />
mains connection on the control<br />
unit<br />
- Replacement/ fuse<br />
Battery voltage too low<br />
- Battery defective or service life<br />
exceeded<br />
- Replacement battery<br />
