:
– ClO
2
production is aborted.
– Alarm relay activated.
Level in the reactor increased too slowly
during NaClO
2
supply between contacts K2
and K3. K3 was not reached in time.
Check correct assembly of the hose from
pump to reactor.
Call Service. In TEST RELAY, check the
NaClO
2
pump.
a) Insufficient performance from the NaClO
2
pump.
For other reasons, see alarm message

O supply 2 timeout:
– ClO
2
production is aborted.
– Alarm relay activated.
Level in the reactor increased too slowly
during the second water addition between
contacts K3 and K4. K4 was not reached in
time.
a) See alarm message

Call Service. In TEST RELAY, check the
solenoid valve. Check the water supply.

9. Timeout process:
– ClO
2
production is aborted.
– Alarm relay activated.
After overflow, it took too long for the reactor
level to drop back down to K1.
a) Air bubbles in the overflow pipe.
Ventilate the system.
b) Insufficient water supply. See alarm
message

10. Timeout overflow:
– ClO
2
production is aborted.
– Alarm relay activated.
During the third water addition, no overflow
from the reactor into the reservoir tank could
be determined.
a) Water supply and solenoid valve.
Call Service. In TEST RELAY, check the
water supply and the solenoid valve.
b) Air bubbles in the overflow pipe. Ventilate the system.
11. Temperature error:
– ClO
2
production proceeds.
Temperature at the measuring cell has
exceeded the set measuring range.
a) Problem with the temperature sensor.
Check the temperature sensor.
Call Service to replace (see the installation
and operating instructions for the measuring
cell).
b) Temperature sensor cable. Check the temperature sensor cable.
Call Service to replace.
c) Water temperature higher/lower than
measuring range.
Check the water temperature.
d) Temperature measuring range set
incorrectly.
Call Service to correct the measuring range.
12. Slope error:
– ClO
2
production proceeds.
Plausibility check for calibration data.
Calibration error at calibration level. Repeat the calibration. Call Service. Clean
the cell, or replace the electrodes.
13. Electrode/buffer fault:
– ClO
2
production proceeds.
Auto reading of buffer data.
Calibration error at calibration level. Repeat the calibration. Call Service. Clean
the cell, or replace the pH probe.
14. Symmetry error:
– ClO
2
production proceeds.
Plausibility check for asymmetry potential pH
calibration data.
Calibration error at calibration level. Repeat the calibration. Call Service. Clean
the cell, or replace the pH probe.
15. pH buffer difference error:
– ClO
2
production proceeds.
Alarm was activated by selecting two buffers
(with "other" buffer selection), which have a pH
difference less than 1 pH. Calibration error at
calibration level. Check the buffer solutions.
Repeat calibration, and replace the probe.
16. Calibration time exceeded:
– ClO
2
production proceeds.
Buffer timeout.
A fault occurred during pH and redox
calibration. An alarm is activated if the
calibration process still does not have a stable
measured value once the time has elapsed.
Calibration error at calibration level. Call Service. Check the pH electrode and
replace, if necessary.
17. Offset error:
– ClO
2
production proceeds.
Calibration error at calibration level.
Only during redox calibration. Repeat the redox calibration, or call Service.
Replace the sensor.
18. Calibrate sensor NaClO
2
/redox:
– ClO
2
production proceeds.
Triggered when the set monitoring time is
reached for the next calibration process
(calibration interval). Calibrate or replace the sensor.
