Cause
During HCl supply, the level in the reaction tank has
increased too slowly between levels K1 and K2.
Level K2 was not reached in time.
a) Insufficient performance of the HCl pump
– Air in suction hose and/or dosing head.
– Pump is not dosing.
– Discharge hose is leaking, clogged, porous or
bent.
b) HCl pump is not sucking in
– Suction hose is leaking, clogged, porous or
bent.
– Deposits at the foot valve.
– Valve is not installed correctly or clogged.
Crystalline deposits in the valves.
– Diaphragm is broken (leaking).
– Valve tappet is torn out.
– HCl container is empty.
c) Flow in the pump not OK.
d) Pump is not running at all.
e) Cable breakage at the controller.
f) Faulty controller.
g) Float switch in the reaction tank damaged.
During NaClO supply, the level in the reaction tank

has increased too slowly between levels K2 and K3.
Level K3 was not reached in time.
a) Insufficient performance of the NaClO

pump HCl.
During the second addition of water, the level in the
reaction tank has increased too slowly between
levels K3 and K4. Level K4 was not reached in time.
a) See alarm message Timeout H2O supply 1.
After overflow, the level in the reaction tank has
dropped back down to K1 too slowly.
a) Insufficient water supply.
During the third addition of water, no overflow from
the reaction tank into the batch tank was determined.
a) Water supply and solenoid valve.
b) Air bubbles in the overflow pipe.
The temperature at the measuring cell has exceeded
the set measuring range.
a) Faulty temperature sensor.
b) Faulty cable of temperature sensor.
c) Water temperature higher or lower than
measuring range.
d) Temperature measuring range set incorrectly.
Plausibility check of calibration data. Calibration fault
at calibration level.
Auto reading of buffer data. Calibration fault at
calibration level.
Remedy
Check the hose from pump to reaction tank
for assembly faults. Call Service.
Check the discharge hose. Call Service to
replace.
• Check the suction hose and suction
lance.
• Call Service to clean or replace the foot
valve.
• Call Service to clean the valves.
• Call Service to replace the diaphragm.
• Check the fill level of the HCl container.
• If "empty HCl" is signalled, replace the
HCl container.
Vent the system.
