4. In the context menu, select [Starting the installation assistant].
5. Select [Save and next] until you reach the Irradiation temperature step.
6. Under Module temperature and External temperature, select the required setting value
for the temperature display in the event of an error.
7.3 Configuring the Irradiation Sensor
You must set the irradiation sensor to current or voltage operation depending on the connection
type (current or voltage) and configure the characteristic curve of the irradiation sensor.
You can set the current or voltage operation and configure the characteristic curve via the device
parameters or using the installation assistant.
