Fault display
Cause / effect
Measures
1.
Disinfectant (chlorine
container) empty ALARM:
Chlorine container empty
This notification serves for
information purposes only, no
action ensues. The disinfection
dosing and booster pump run
on.
1. Refill chlorine, or change container
2. If the container/hopper is not empty, recalibrate
the empty switch or
3. Renew the empty switch.
2.
Acid empty ALARM:
Acid container empty
The acid dosing stops and the
booster pump runs on.
Caution:
Chlorine dosing with-
out acid may lead to blockage
in the dissolving device.
1. Replace the empty acid container with a full one
2. If the acid container is not empty, the empty
switch is faulty.
3. If the suction lance is new, check the functional
direction of the float
3.
Chemical container level
reserve MESSAGE
This message is only for infor-
mation, there is no action.
Provide for appropriate supplies.
4.
Pressure minimum
ALARM:
The flow pressure at the booster
pump is too low
Dosing is being stopped. The
booster pump has been
deactivated.
1. Supply pressure too low
2. Booster pump faulty
3. Pressure switch faulty
4. Set a lower response pressure at the pressure
switch
5.
Flushing tank level
minimum ALARM:
The water level in the flushing tank
is low; more water is suctioned off
than runs into the flushing tank
through the float valve.
Dosing is being stopped. The
booster pump has been
deactivated.
1. Float valve function:
a)
The water inflow should gently follow the float's
movement. When OK, calibrate the water level.
See OI Dosing unit, section Commissioning
b)
If this is not the case, insert a new membrane in the
float valve.
2. Insert a pinhole aperture with a small drill hole
3. Prefilter (Pos. 9) contaminated
clean
6.
Flushing tank level
maximum ALARM:
The water level in the flushing tank
is too high, less water is being
siphoned off than is flowing into the
flushing tank through the float
valve.
Dosing is being stopped. The
booster pump runs on.
1. If the injector's suction flow is OK:
a)
Float valve function:
The water inflow should gently follow the float's
movement. When OK, calibrate the water level.
See OI Dosing unit, section Commissioning
b)
If this is not the case, insert a new membrane in
the float valve.
2.
If the suction flow is not sufficient, see under
fault display
"Suction line flow minimum
ALARM"
7.
Suction line flow
minimum ALARM:
The water flow in the venturi
suction line is too low. The
switching body of the flow switch
does not rise, the switch LED lights
up.
Dosing is being stopped. The
booster pump runs on.
1.
Check booster pump functioning.
2.
Prefilter dirty
clean (GR only)
3.
Blocked suction opening in the flushing tank
4.
There may be particles in the nozzle or in the
suction line, due to particles entering during
Installation or from the chlorine
5.
Insert a pinhole aperture with a larger drill hole
or remove it entirely
6.
Blocked check valve at the buffer tank
7.
Diffuser worn out, if D > 6.5mm, replace
diffuser
8.
Chlorine dosing monitor
in cyclone ALARM:
The optical sensor on the dissolving
cyclone is activated.
The sensor on the cylcone
indicates that after the 2nd
dosing interval there is
insufficient chlorine in the
cyclone.
1. Fault during dosing:
a)
Clotting in chlorine granulate
b)
Dosing screw blocked due to poor chlorine
quality (too fine, moist)
2. The dosing motor is defective.
3. Calibrate the optical sensor.
9.
Chlorine dosing motor
fuse ALARM:
Supply 24V of sensors- fuse F1
please check indications in the
Log-data
The chlorine dosing stops and
the booster pump runs on.
At blown fuse F1: dosing and
booster pump stops.
Check chlorine motor for blockages, remove
blockage if necessary and replace fuse.
Check acid dosing motor – replace the fuse.
Check sensors “chlorine empty, chlorine missing,
suction flow switch venturi”
