IMPORTANT!
Once the enable code has been entered correctly, it is no longer necessary to re-enter the
code during further programming procedures. The flashing values or settings appear
directly when the ENTER key is pressed.
The enable is deleted automatically 5 minutes after the last time a key is pressed or after
returning to the trend or standard display.
4.3.1 Trend Display
The trend display serves the purpose of monitoring the lamp ageing process, the formation of a
coating on the protective tubes or changes in the water quality.
The progression of the UV sensor signal is displayed in a time window. Horizontal lines denote
the safety threshold and warning threshold. The short vertical lines indicate switch-on operations
of the UV disinfection system. The display range of the UV sensor signal is between 0 W/m
2
(or %) and the value that was assigned to the analogue output value of 20 mA (see 4.3.11). The
time window is adjustable (see 4.3.8) and provides a continuous display: After the selected time
has elapsed, the oldest value is deleted and the new value displayed.
IMPORTANT!
• Each calibration of the UV-C sensor is documented by a solid vertical line in the trend
display.
• The content of the trend display is deleted when the display range is changed and when
the operating hours counter is reset.
