Enter a correct activation code.
10004
10005 System tempera‐
ture too high
Temperature
sensors in the
control cabinet
The temperature in
the control cabinet
or the HV trans‐
former temperature
is too high.
Check that the control cabinet fan is
working correctly. Clean the fan filter.
Lower the ambient temperature,
for instance by installing an air condi‐
tioning system. Set a lower ozone
output.
Only with air conditioning unit: Check
that the air conditioning unit is oper‐
ating correctly.
10008 Ozone alarm Ozone detector Ozone gas leak Read the safety information before
entering the room. Under no circum‐
stance restart the system before the
cause of the ozone alarm has been
localised and eliminated. Locate and
seal the ozone gas leak.
10009 Maintenance

nance exceeded
Perform maintenance on schedule
10011 Guard doors
open.
Monitor the door
switch
The contact in the
door switch has trig‐
gered
Close the control cabinet door.
10012 24 V supply to
the control has
failed
Monitor the
supply voltage
for the control
The supply voltage
at the control inputs
has been lost.
Check the micro fuses on the commu‐
nication PCB and replace as neces‐
sary. Replace the communication
PCB.
10015
11086 Gas flow too low Gas flow sensor The feed gas flow
through the ozone
generator is too
low.
Check the system priming pressure
and increase if necessary. Check for
excessive back pressure in the ozone
generator and, if necessary, lower the
process water pressure. Check that
the solenoid valves in the gas section
are working correctly. Correct the gas
flow at the needle valve (6).
10016
11087 Gas flow too
high
Gas flow sensor The process gas
flow through the
ozone generator is
too high
Check the system priming pressure
and reduce if necessary. Check for
excessively low back pressure in the
ozone generator and, if necessary,
raise the process water pressure.
Correct the gas flow at the needle
valve (6).

generator pres‐
sure sensor
Sensor meas‐
uring signal
Sensors are not
connected or are
emitting an implau‐
sible analogue
signal, e.g. > 21 mA
or < 3.6 mA.
Check the sensors' connection cable,
check the analogue signals, if neces‐
sary replace the connection cable or
the sensors.
10021 No SD card --- Warning: SD card
not inserted or
faulty
Insert the SD card into the SD card
slot or replace the SD card.
