– Combined and setpoint
controller stop, and restart
after fault elimination.
21. Cleaning motor fault:
– ClO production proceeds.
2
– Alarm relay activated.
– Combined and setpoint
controller stop, and restart
after fault elimination.
22. "dosing time ClO2 exceeded":
– ClO production proceeds.
2
– Alarm relay activated.
– Controller stops the ClO dosing

pump, until the fault is
eliminated.
Cause
Plausibility check the calibration data for asymmetry
potential of pH. Calibration fault at calibration level.
Two buffers with a pH difference of less than 1 pH
were selected with buffer selection "other".
Calibration fault at calibration level.
Buffer timeout. Fault during pH and ORP calibration.
An alarm is activated, if the calibration process does
not have a stable measured value, if the time has
elapsed. Calibration fault at calibration level.
Calibration fault at calibration level. Only during ORP
calibration.
The set monitoring time is reached for the next
calibration process (calibration interval).
a) The float of the measuring cell is above the water
sensor. The flow is too big.
b) The float of the measuring cell float is below the
water sensor. The flow is too small.
c) The sample-water extraction device or the hose
to the measuring cell is clogged or leaking.
d) No sample-water flow in the measuring cell.
Filter clogged.
e) Lack of water at the sample-water extraction
device.
f) Faulty water sensor.
g) Faulty cable from the measuring cell to the
controller.
h) Faulty controller.
i) Setting in the "maintenance > water sensor >
N.C./N.O." menu does not correspond with
terminal connections.
Cleaning motor monitoring in the measuring cell
indicates a fault.
a) Faulty cleaning motor.
b) No power supply to the cleaning motor.
Cable breakage.
c) Gas bubbles in the measuring cell.
The controller predefines maximum capacity for a
longer period than the set time.
a) After a power supply failure, the solution in the
batch tank has been diluted too much after
flushing (setpoint and combined controllers).
b) Poor water quality (setpoint and combined
controllers).
c) Faulty water flow meter, or wrong setting of
water flow meter (proportional and combined
controllers).
d) Faulty measuring cell cable or measuring cell.
e) HCl or NaClO container contains only water.

Controller is set incorrectly.
Remedy
Repeat the calibration. Call Service to
clean the measuring cell or to replace the
pH electrode.
Check the buffer solutions. Repeat the
calibration, and call Service to replace the
electrode.
Check the pH electrode and call Service to
replace, if necessary.
Repeat the ORP calibration, or call Service
to replace.
Calibrate or call Service to replace the
electrode.
Stop the controller.
Reduce the flow with the adjustment
spindle of the measuring cell.
Increase the flow with the adjustment
spindle of the measuring cell.
Check the sample-water extraction device
and the hose to the measuring cell.
Clean the filter of the measuring cell.
Check the flow in the main line at the
sample-water extraction device.
Call Service to replace the water sensor.
Call Service to replace the cable.
Call Service.
Setting can only be corrected with the
super user code.
Stop the system.
Check the power supply of the cleaning
motor. Call Service to replace the cleaning
motor.
Check the cable. Call Service to replace the
cable.
Vent the measuring cell.
Continue operation after flushing.
Measure the water quality and the chlorine
dioxide concentration in the main line.
Call Service to replace.
Check the measuring cell cable.
Call Service to replace.
Replace the HCl or NaClO container.
