Twilight Sensor; Rain Sensor; Temperature Sensor - Siemens SIMATIC HMI KTP400 Manual

3 Mode of Operation
3.1.3

Twilight sensor

The twilight sensor is processed in the LOGO! program in the lighting control.
In automatic mode, all exterior lights are automatically switched off at sunrise
(> 10 lux) and switched on at dusk (< 10 lux) via function block "twilight"
(B187/analog threshold trigger).
Manual switching of lights takes highest priority, even if the automatic mode is
activated.
The function block "twilight" can be called up in parameter assignment mode with
the respective block name using the LOGO! display or LOGO! TDE. This makes it
possible to individually adjust the threshold value for automatic switching off and on
of the lighting.
3.1.4

Rain sensor

The rain sensor is processed in the LOGO! program in the program parts garden
watering and roof hatch.
In automatic mode, if it does not rain, the garden watering is switched on
automatically in the morning at 09:00 a.m. and in the evening at 08:00 p.m. for 10
minutes via the function block "watering" (B104/Weekly Timer).
If automatic mode for the roof hatch has been activated, it will automatically close
when it rains. If it does not rain and the temperature is high, the roof hatch will
open.
The function block "watering" can be called up in parameter assignment mode with
the respective block name using the LOGO! display or LOGO! TDE. This makes it
possible to adjust days and times in the weekly timer for automatic garden
watering.
3.1.5

Temperature sensor

The temperature sensor is processed in the LOGO! program in the program part
roof hatch. In automatic mode, the roof hatch is opened via function block "auto
roof" (B105) at high temperature (here, >28 °C) and closed at low temperature
(here, <25°C).
In automatic mode, all heating is switched off via function block "temp out"
(B195/analog threshold trigger) with >22 °C outside temperature.
The function block "temp out" can be called up in parameter assignment mode with
the respective block name using the LOGO! display or LOGO! TDE. This makes it
possible to individually adjust the threshold value for automatic switching off of the
heating.
