Supplementary fresh
water active
The fresh water injection to supplement
water loss in the system is active.

Cause
Rectification
Unit motor protection
Overload of an electrical unit.
1 Activate the motor protection circuit breaker.
2 If this is unsuccessful then contact the Service agency
responsible.
Control air failure
The control air supply to the control cabinet
has failed.
1 Search for the cause of the absent compressed air sup-
ply.
Min. tank level
The tank has reached its minimum filling
level.
1 Contact customer service to determine the possible
cause of the min. filling level.
Max. tank level
The tank has reached its maximum filling
level.
1 Contact customer service to determine the possible
cause of the overfilling of the tank.
Level sensor error
The sensor used for measuring the level /
pH / conductivity has a malfunction.
1 Contact the service agency responsible.
UV system malfunction
1 Search for the cause of the malfunction at the control
cabinet for the UV system.
2 Contact the service agency responsible.
Battery faulty
The charge state of the battery is 0 %.
1 Replace the battery.
All stored data is lost if a controller with a faulty battery
is switched off.
Immersion pump check
The pump no longer provides the neces-
sary pressure for operating the system.
1 Contact the service agency responsible.
Sludge trap oil alarm
Too much oil is present in the sludge trap
(oil layer).
1 Have the oil layer disposed of by an approved disposal
company.
Fault
Rectification
The processed water is
cloudy despite no malfunc-
tion messages on the device.
1 Check the cleaning agents for biological compatibility and correct dosage. Contact the service
agency responsible regarding this.
2 Check that the fresh water injection has been set to 20-25 l fresh water per vehicle. Contact the
manufacturer of the washing facility regarding this.
3 Check if servicing of the tank is due and perform this if necessary.
Water backing up in the
sludge trap.
1 Clean the insertion-sieve box (see Chapter Insertion-sieve box servicing (standard version)).
Odours are generated despite
no malfunction messages on
the device.
1 Check the aeration in the aeration tank. A fine bubbled, evenly distributed aeration should be visible
on the surface.
2 Check the aerator unit and perform maintenance if necessary (see Chapter Aerator servicing).
3 Check the aerator lines for damage that may result in a loss of air.
The immersion pump is not
pumping water into the
above-ground tank, despite
no malfunction messages on
the device.
1 Check that water is present in the sludge trap being used as a water removal tank.
2 Check if any pipes in the system are clogged.
3 Check if backwater has occurred in the sludge trap chain. In particular, the light liquid separator and
coalescence separator and insertion-sieve box are to be checked (see Chapter Sludge trap ser-
vicing). If no backwater is present then have the agreed minimum fresh water injection at the last
flushing operation confirmed by the manufacturer of the washing facility.
4 It the minimum fresh water intake volume is correct then check the sludge traps for leaks.
The system has been com-
pletely switched off.
1 Stop washing operations because only enough processed water for a single wash remains.
Note
Odours can develop if the system is switched off for several days without draining water from the
tanks.
1 Switch on the system.
If the system is switched on after a longer standstill period, it will take a few days before the original
cleaning performance is reached. When switched on, the control system assumes control of the
coordination of the system.
2 Acknowledge the malfunction messages and emission of the acoustic horn signal occurring in the
case of insufficient water in the processed water tank.
