1 About this system
Dulcodes A UV systems are used for disinfection and to support
the disinfection of:
nPotable water
nProcess water
nSwimming pool water
In the treatment of swimming pool water, harmful substances, such
as chloramines, can be effectively reduced by UV radiation and
also germs, which are difficult to combat with chlorine, can be
safely killed. UV radiation is proven for the reduction of inorganic
combined chlorine. Organically bound chlorine is generally more
stable and cannot be reduced by UV radiation.
Dulcodes UV systems are supplied ready for connection. They are
available in different designs, defined by their identity code. The
performance data can be found in the data sheet enclosed with the
Dulcodes UV system.
Scope of supply:
nRadiation chamber
nLamp with lamp protection tube
nUV-C sensor
nTemperature switch
nAutomatic wiper
nControl cabinet with control
nDocumentation

5 Function
The water to be treated flows through the stainless steel radiation
chamber past the UV lamp. UV radiation kills the germs and
destroys substances, like chloramines, in the swimming pool water.
The UV medium pressure lamp produces UV-C radiation. The UV
lamp is located in a quartz lamp protection tube with good UV
transparency.
The design of the radiation chamber and the flow of radiation
deliver even irradiation of the entire flow of water.
A control monitors the UV system in conjunction with the UV
sensor.
Shut-off valves and rinse valves do not form part of
the scope of delivery
The shut-off valves and rinse valves do not form
part of the scope of delivery of the UV system and
are provided by the operator on site.

5.1 Commissioning
Once the UV system has been switched on, the UV lamp is ignited.
Following ignition, the UV lamp requires approximately 1 ... 3
minutes until it has reached its operating temperature.
If the safety threshold is not exceeded within the maximum permis‐
sible warm-up time, the controller switches the UV-system off and
goes into fault mode.
The UV-C sensor monitors the UV lamp: As soon as the UV output
has exceeded the warning threshold, the rinse valve opens for the
start rinse.
After the start rinse, the shut-off valve opens and the UV system
starts normal operation.

Function
16

5.2 Normal mode
In normal mode, the UV sensor continues to monitor the UV
output:
If the UV output falls below the warning threshold: a warning is
emitted.
If the UV output falls below the safety threshold: The shut-off valve,
fitted on site, closes, a wiper cycle is triggered and the flushing
valve, fitted on site, opens.
The UV system switches off and enters fault mode
if the safety threshold is still not exceeded after
completion of one wiping cycle.
In this mode, the operator of the UV system has to
ensure, for the purpose of disinfecting the water,
that the flow of water is reliably interrupted and no
unradiated water can be conveyed.
5.3 Controlled operation
UV radiation is automatically adjusted in controlled operation. The
UV sensor measures the UV output and forwards the measured
UV current value to the control. The UV setpoint is either entered
directly in the control (operating mode: control, internal [INT] ) or
using a variable 4 ... 20 mA standard signal (operating mode: con‐
trol, external [EXT] ).
5.4 Automatic wiper
During the wiper process, the warning and safety
thresholds are not monitored, consequently the
shadowing caused by the wiper does not trigger a
false alarm.
If you press the [F3] key [Wiper] in the standard display, then the
wiping process is triggered. This is independent of whether the
system is ‘ON’ or ‘OFF’ .
If you have activated regular wiping, then a wiping cycle occurs
automatically after the set interval has elapsed.
If the interval is set to [0] , then regular wiping is deactivated.
5.5 Temperature Monitoring
The water temperature in the radiation chamber is monitored
throughout the entire time the UV lamp is operating.
As soon as the water temperature exceeds the maximum tempera‐
ture, the UV system goes into fault mode.

Function
17

5.6 Switching off
When the Off button on the UV control is pressed, the UV lamp
switches off once the set post-burning time has elapsed. The fac‐
tory setting is 30 seconds.
If you wish the UV lamp to switch off as soon as you have pressed
the off button, then you need to set the post-burning time to 0 sec‐
onds.
5.7 Cool down
As the UV lamp can only be re-ignited after switching off of the UV
system and sufficient cooling, the system goes into cooling down
mode.
During cooling mode, the UV system cannot be started. After the
pause status has been cleared during cool-down or [START] has
bee pressed during cooling down, the UV system only restarts after
the cooling-down period has ended.
5.8 Behaviour should the supply voltage fail
If the power fails, once the power supply has been reconnected the
UV system returns to the operating status in which it was before
the power failure.
40 seconds are needed to ramp up the HMI. The PLC (Program‐
mable Logic Controller) is ready for operation considerably faster.
To avoid ambiguous operating indicators and operating statuses,
operation is only enabled after 45 seconds.
When operation starts, all pending faults are reset if these faults
are no longer present. If the wiper is not in the home position, it is
moved back. If the power fails while the UV system is in operation,
then the system is always cooled down before being started
regardless of how long the power failure lasted. The cooling-down
phase is not shown on the display, but runs in the background. If
the power failure occurs while the UV system is cooling down, the
cooling down process is continued after the power has been
switched on again.
Should an automatic start not be desirable due to external compo‐
nents, the UV system must be switched from external to pause.
External faults result in a UV system fault, which then has to be
acknowledged. Separate acknowledgement can thereby be
avoided.

6.1 Version
As the electronics and software are continually subject to improve‐
ments, the version number was introduced as a means of identifi‐
cation. This number should be stated in the event of any com‐
plaints. The version number can be called up on the display.
nThe UV medium pressure control, based on a S7-1200, is used
to monitor and control a medium-pressure UV system one to
three medium-pressure lamps.
nThe operating and display unit is an HMI KP 300.
nThe UV lamps are actuated and monitored via an electronic
ballast.
nThe UV power is monitored.
nThe temperature of the radiation chamber and control cabinet
is monitored.
nThe wiper is controlled and monitored.
nSeveral valves can be controlled.
nSeveral additional inputs and outputs are used to operate the
UV system.
nThe lamp power can be controlled.
nOperating actions and events are recorded and saved together
with the date and time.
– The data can be displayed in tabular form on the display.
nThe radiation intensity or the lamp power is recorded and
saved at regular intervals together with the date and time.
– The radiation intensity can be presented as a simple dia‐
gram on the display.
Varying doses of UV may be necessary depending on the applica‐
tion. Often 600 J/m² is used to reduce combined chlorine and
400 J/m² for disinfection. The UV dose is calculated from the trans‐
mission of water and the water flow; refer to the data sheet for your
UV system. When calculating the UV dose, in accordance with the
data sheet, take into account ageing of the lamp and contamination
of the UV system, as well as possible transmission fluctuations in
the water quality.
If the transmission of water is not known, it must be calculated
when commissioning the UV system and checked with the max‐
imum permissible flow at the desired UV dose. The maximum flow,
as stated on the data sheet, must not be exceeded.
The UV system has over two freely adjustable output levels. The
control has a digital contact input to switch between these two
output levels. You can connect a suitable swimming pool controller
to measure the combined chlorine to this digital contact input in
swimming pool water treatment. In normal operation, the UV
system disinfects with with 400 J/m2. Should the swimming pool
controller measure too high a chloramine value, the UV system is
operated at 600 J/m 2, via the digital contact input, until the chlora‐
mine value calls again below the limit value set on the swimming
pool controller. This two-stage controller is not used when disin‐
fecting potable water.

6.2 Display of UV dose and radiation intensity (UV intensity)
The UV sensor monitors the radiation intensity of the UV system.
The radiation intensity (UV sensor signal) is given in W/m2 and is
displayed on the main screen of the HMI.
The UV dose is calculated depending on the:
nUV transmission,
nflow,
nradiation intensity.
The control calculates the UV dose displayed from this value.
