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.
n
The 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.
n
The operating and display unit is an HMI KP 300.
n
The UV lamps are actuated and monitored via an electronic
ballast.
n
The UV power is monitored.
n
The temperature of the radiation chamber and control cabinet
is monitored.
n
The wiper is controlled and monitored.
n
Several valves can be controlled.
n
Several additional inputs and outputs are used to operate the
UV system.
n
The lamp power can be controlled.
n
Operating actions and events are recorded and saved together
with the date and time.
– The data can be displayed in tabular form on the display.
n
The 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/m 2 . 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.
