5 Configuration
Since the RA100 T consists of two sensors (irradiation and temperature), two sensors must be
programmed:
5.1 Irradiation Sensor
5.1.1 Configuring the Sensor with the Sunny Boy Control Plus
To configure the Sunny Boy Control Plus suitably for the connected irradiation sensor, proceed as
follows:
1. Log in to the Sunny Boy Control Plus as the installer.
2. Select the menu option "Setup > Plus I/O > Anlalog In" in the Sunny Boy Control Plus.
3. Select the input port that is to be configured.
4. Under "Function", select the desired measuring range (± 500 mV).
5. Under "Name", enter the desired sensor name (e.g. RA100T).
6. Under "Unit", enter the desired unit (W/m²).
7. Under "Gain", enter the desired gain. The gain V is calculated from the value specified on the
type plate for the measurement voltage at 1000 W/m² and at 25 °C as follows:
V = 1000 / measurement voltage at 1000 W/m²
8. Under "Offset", enter the value 0.
☑ The sensor is configured.
5.1.2 Configuring the Sensor with the Sunny Central Control
To configure the Sunny Central Control suitably for the connected irradiation sensor, proceed as
follows:
1. Log in to the Sunny Boy Control Plus as the installer.
2. Select the menu option "Device Set-up > Interfaces > Analog In" in the Sunny Central Control.
3. Select the input port that is to be configured.
4. Under "Function", select the desired measuring range (± 500 mV).
5. Under "Name", enter the desired sensor name (e.g. RA100T).
6. Under "Unit", enter the desired unit (W/m²).
7. Under "Gain", enter the desired gain. The gain V is calculated from the value specified on the
type plate for the measurement voltage at 1000 W/m² and at 25 °C as follows:
V = 1000 / measurement voltage at 1000 W/m²
8. Under "Offset", enter the value 0.
☑ The sensor is configured.
